DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031] FIG. 1 is a structural diagram of a dismountable hand grip of the present invention. As shown in the figures: the dismountable hand grip comprises a connection block 1, a hand grip 2, two locking pieces 3, an elastic component 4 and two pins 5. There is a connection chamber at a front part of the hand grip 2. The two locking pieces 3 are set inside the connection chamber and are symmetrically connected to the front part of the hand grip 2 through the pins 5, in order to enable the locking piece 3 to rotate around pins 5 inside the connection chamber. There is a clip unit 31 at the front part of the locking pieces 3, and a pressing unit is provided at a back part of the locking pieces 3 and is connected with the hand grip 2 via the elastic component 4. At the back part of the connection block 1, there is a connection unit which is able to be inserted into the connection chamber. The connection unit is provided with a clip slot 12 which corresponds with the clip unit 31.

[0032] During a process of assembly, use two fingers of one hand (such as the thumb and the index finger) to press pressing areas of the two locking pieces 3 (back end) respectively. At this moment, the elastic component 4 between the pressing areas contracts towards a central axis of the hand grip 2, and also the front parts of the two locking pieces 3 assume an opening state at the same time. Then, wrap the back part of the connection block 1 into the connection chamber of the front part of the hand grip 2, and then release the pressing area. At this moment, through an elastic restoring force of the elastic component 4, the two clip units 31 at the front part of the locking pieces 3 will be blocked inside of the clip slot 12 of the connection unit at the back of the connection block 1 respectively. Therefore, assembling hand grip 2 and connection block 1 are able to be realized by one hand effortlessly and conveniently.

[0033] During a process of disassembly, use two fingers of one hand (such as the thumb and the index finger) to press the pressing areas of the two locking pieces 3 (back end) respectively. At this moment, the elastic component 4 between the pressing areas contracts towards the central axis of the hand grip 2, and the front parts of the two locking pieces 3 assume an opening state. At this moment, the clip units 31 at the front part of the two locking pieces 3 separate from the clip slot 12 of the connection unit at the back part of the connection block 1 respectively. Next, separate the back end of the connection block 1 from the connection chamber at the front end of the hand grip 2. Consequently, disassembling hand grip 2 and connection block 1 are able to be realized by one hand effortlessly and conveniently.

[0034] While realizing simple operation by one hand, it has also been found that both the locking pieces 3 of the present invention are located inside the connection chamber at the front end of the hand grip 2 (the front end of the locking pieces 3 would slightly reveal hand grip surface only during pressing). Compared to the technology in prior art, not only a volume of the hand grip 2 of the present invention is not increased, but also an aesthetic value of a product has not been reduced.

[0035] FIG. 2 shows a preferred embodiment of the present invention. Said elastic component 4 (such as the spring) is provided at both sides of the central axis of the hand grip 2 respectively. In this way, the pressing force will be more balanced when the locking piece 3 is operated. In addition, the entire outer end of the elastic component 4 is connected with the back part of the locking piece 3, and the entire inner end of the elastic component 4 is fixed to a fixation area of both sides of the central axis on the hand grip 2. At the back part of the locking piece 3, the fixing hole 31 of the elastic component 4 is able to be provided for connecting the outer part of the elastic component 4. The fixing hole 24 of the elastic component 4 is also provided on both sides of the hand grip 2 for connecting the inner end of the elastic component 4.

[0036] As an option, the fixing holes 24 and 31 of the elastic component are also able to be replaced with a fixing column, or other fixing structures.

[0037] Of course in case only one elastic component 4 is used, and meanwhile both sides of the elastic component 4 are fixed on the back part of both locking pieces 3, the objective of the present invention can also be realized. The only thing should be concerned is that while pressing, the balance of the pressing force shall be considered. If the balance needs to be achieved, it is apparent that requirements for the elastic component 4 are relatively high.

[0038] According to FIG. 2, both sides of the front part of the hand grip 2 are provided with a pin hole 22 for inserting the pin 5. In addition, there is the fixing hole 21 and a locating slot 25 of the locking piece 3 for assembling and locating the locking piece 3.

[0039] A convenient implementation structure for assembling and disassembling of the present invention is described as above. Based on the above-mentioned implementation structure, waggle problem between the hand grip and the connection block is also further considered, detailed implementation structure is as blow:

[0040] As mentioned above, the clip units 31 at the front part of the two locking pieces 3 are blocked inside the clip slot 12 on the connection unit at a back of the connection block 1, which realizes the first clip fastening structure between the hand grip 2 and the connection block 1. However, problems like unstable fastening and waggling in prior art still exist. These problems are solved as follows:

[0041] Additional fastening unit one: according to FIGS. 1, 2 and 3, two guiding slots 25 of the connection block 1 are provided at the front part of the hand grip 2, and the two guiding slots 25 of the connection block 1 are separated by utilizing a reinforcing plate 26. Correspondingly, two guiding orientation columns 11 which match with the two guiding slots 25 of the connection block 1 are located behind the connection unit of the connection block 1 (clip slot 12 is set outside such guiding orientation columns 11 respectively). Between the two guiding orientation columns 11, there is a fixing gap for the reinforcing plate 26 to insert. During usage, the reinforcing plate 26 at the front part of the hand grip 2 is inserted into the fixing gap between two guiding orientation columns 11 of the connection block 1, so as to enhance the degree of combining steadiness between the hand grip 2 and the connection block 1.

[0042] Functions of such reinforcing plate 26 are mainly reflected in: (1) The reinforcing plate 26 separates the two guiding slot 25 of the two connection blocks. (2) The reinforcing plate 26 is provided inside the connection chamber in order to enhance the strength of the connection chamber. (3) The reinforcing plate 26 plays a guiding role for the orientation column 11 to insert into the guiding slot of the connection block.

[0043] As a preferred embodiment: The reinforcing plate 26 is provided with a slope on both sides. A form between the two slopes is narrow outside and wide inside. Correspondingly, the fixing gap between the guiding orientation columns 11 is also narrow outside and wide inside. In this way, the degree of combining steadiness between hand grip 2 and the connection block 1 is able to be further reinforced.

[0044] Additional fastening unit two: According to FIGS. 1, 2 and 3, the outside of the two guiding slots 25 of the connection block of the hand grip 2 are provided with the fixing step 27. Such fixing step 27 matches with an edge of the connection block 1 to reinforce the degree of combining steadiness.

[0045] Additional fastening unit three: According to FIGS. 1, 3 and 4, a fastening convex unit 34 is located at a root of the clip unit 31 of the locking piece 3. The fastening convex unit 34 cooperates with the fastening slot 13 around the clip slot top of the connection block 1 to reinforce the degree of combining steadiness between the hand grip 2 and the connection block 1.

[0046] Additional fastening unit four: According to FIGS. 1, 3 and 4, the outside of the top of the two guiding orientation columns 11 is provided with the fastening slope 14. The fastening slope 14 cooperates with the fastening slope 35 at a pin joint on the locking piece 3 to reinforce the degree of combining steadiness between the hand grip 2 and the connection block 1.

[0047] During practical usage, the four additional fastening units mentioned above are able to be used separately or in combination. No matter under what kind of situation, they will play a role in solving the waggle problem between the hand grip and the connection block. Generally, the additional fastening unit one will be mainly considered to be used together with the additional fastening unit two, or the additional fastening unit three will be considered to be used together with the additional fastening unit four. Through tests, it is found that a best implementation mode for the present invention is to use the four additional fastening pieces mentioned above altogether.
