DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(8) In order to make people have a direct and complete understanding of the technology scheme of the present invention, here the following unlimited instructions are given combined with the appended figures.

(9) As shown from FIG. 1 to FIG. 6, the gecko gun includes a housing 100 with a left handle 1 on the bottom and a right handle 2. The left handle 1 and right handle 2 are all covered by a handle housing 3 and 4. The housing 100 is installed with a U-shaped seat 5 at the top end. The top end of the right handle 2 is rotated with the top, end of the housing 100 through a spindle 6. The top end of the right handle 2 is installed with a link mechanism 7, which is covered by the housing 100 and fixed to the housing 100 via screws. The link mechanism 7 includes a first linkage assembly 71 linked to the top end of the right handle 2 and a second linkage assembly 72 connected to the first linkage assembly 71, and the second linkage assembly 72 is used to drive the U-shaped seat 5 to shift forward and backward.

(10) The first link assembly 71 comprises two paralleled first link rods 711 with the same shape and size. One end of the first link rod 711 is fixed to the top end of the right handle 2. The second link assembly 72 comprises two second link rods 721 which are fixed to the top end of the right handle 2 by one end and below the first link rods 711 and a connecting rod assembly 722 installed on one end of the second links 721 to drive the U-shaped seat 5 to shift forward and backward. The two first link rods 711 are installed with a first pin 8 on one end, and a long chute 9 on the other end. The top end of the right handle 2 is provided with a first pin hole 10 for the first pin 8 to be inserted by upper and lower ends. The two second link rods 721 are installed with a second pin 11 on one end, and a short chute 12 on the other end. The top end of the right handle 2 is provided with a second pin hole 13 for the second pin 11 to be inserted by upper and lower ends. The connecting rod assembly 722 comprises two connecting rods 7221, and the first concave boss 7222 and second concave boss 7223 fixed to two ends of the connecting rod 7221. The mentioned first concave boss 7222 will go through the long chute 9 and slide with the long chute 9. The second concave boss 7223 will go through the short chute 12 and slide with the short chute 12. The connecting rod 7221 is, provided with a positioning axis 14, the top and bottom ends of which 14 are fixed to the top end of the housing 100. On the top end of the housing 100, there is a fixing hole 27 for the fixation of the positioning axis 14.

(11) The distance between the positioning axis 14 and the first concave boss 7222 is longer than the distance between the positioning axis 14 and the second concave boss 7223. When the connecting rod moves, since the position of the positioning axis 14 and the housing 100 will not change when fixed, there will be an arm of force between the positioning axis 14 and the first concave boss 7222, while another arm of force will also be formed between the positioning axis 14 and the second concave boss 7223. Since the short chute 12 is much shorter than the long chute, the distance between the positioning axis 14 and the first concave boss 7222 is two times longer than the distance between the positioning axis 14 and the second concave boss 7223.

(12) In order to facilitate the connection between the U-shaped seat 5 and the first concave boss 7222, a punching hole is installed on the inner side of the U-shaped seat 5. The upper and lower ends of first concave boss 7222 are fixed in the punching hole 15, and a positioning slot 16 is provided on the other end of the U-shaped base 5. The housing 100 is provided with a neck 17 on one side of the top end corresponding to the positioning slot 16. When installing the gecko peg, lock the inner end of the peg in the neck 17, and the core of the peg will be locked in the positioning slot 16. When riveting gecko peg, pull the core of the peg through the U-shaped seat 5, so as to rivet the peg exposed outside of the housing 100.

(13) The top end of the right handle 2 is further provided with a third pin hole 18, and the first pin hole 10, third pin hole 18 and second pin hole 13 are set from top to bottom. The spindle 6 is set through the third pin hole 18. The top end of the housing 100 is provided with a positioning hole 19 for the upper and lower ends of the spindle 6 to be locked into. The spindle 6 is covered by a torsion spring 20. The torsion spring 20 has two bifurcations 201, wherein one of the bifurcation 201 abuts against the second pin 11 and its 201 lower end locks into the left handle 1; the other bifurcation 201 abuts the connecting rod 7221, and its 201 lower end locks into the right handle 2. The distance between the first pin hole 10 and the third pin hole 18 is shorter than the distance between the second pin hole 13 and the third pin hole 18, so there will be an arm of force formed between the first pin 8 and the spindle 6 and an arm of force formed between the second pin and spindle 6. In order to make it most energy-saving when pulling or pressing right handle 2, the distance between the second pin 11 and the spindle 6 shall be two times longer than that between the first pin 8 and the spindle 6 at least.

(14) The top end of the left handle housing 3 is provided with a hook 21, and one end of the hook 21 locks on the outer wall of the right handle 2. The set of the torsion spring 20 will facilitate the opening of right handle 2. In order to close up two handles, right handle 2 and left handle 1, people can only cover the outer wall of the right handle 2 with the hook 21.

(15) In order to achieve a stable fixation of the housing 100 and the connecting rod assembly, housing 100 is provided with a long cover plate 22 and short cover plate 23 on two sides of the top end. The long cover plate 22 has a cylinder 24 with threaded hole. The housing 100 is provided with a through hole 25 on the top end for the cylinder 24 to go through. The cylinder 24 goes through the through hole 25 and then will be fixed to the short cover plate 23 by a fastening screw (26).

(16) As shown in FIG. 5 and FIG. 6, FIG. 5 is the schematic diagram of the folding state of link mechanism, and FIG. 6 is a diagram of the opening state of link mechanism. When using, open the right handle 2 first and it will drive the first link rod 711 to move forward, while the second link rod will be driven to move backward, thus the U-shape seat will be driven to move forward. At first, the first concave boss 7222 stays at the end of the long chute 9, and when the second concave boss 7233 is slid to the front end of the short chute 12, the connecting rod 7221 interferes. Since the second concave boss 7233 is always pulled backward by the second link rod 721 the end of the connecting rod 7221 which is equipped with the second concave boss 7233 will move backward, while the other end of the connecting rod will move forward, thus making the first concave boss 7222 drive U-shaped seat 5 to move forward. Therefore, there will be 2 driving forces when U-shaped seat 5 moves, and the opening of right handle 2 is energy-saving. Finally, the first concave boss 7222 will be led to the front end of the long chute 9 by the connecting rods 7222.

(17) Similarly, when riveting gecko peg, hold left handle 1 and right handle 2. Press right handle 2 tightly. Firstly, the right handle 2 will drive the first link rod to move backward and the second link rod to move forward, thus the U-shaped seat 5 will be driven to move backward. At first, the first concave boss 7222 stays at the end of the long chute 9, and when the second concave boss 7233 is slid to the front end of the short chute 12, the connecting rod 7221 interferes. Since the second concave boss 7233 is always pushed forward by the second link rod 721, the end of the connecting rod 7221 which is equipped with the second concave boss 7233 will move forward, while the other end of the connecting rod 7221 will move backward, thus making the first concave boss 7222 drive U-shaped seat 5 to move backward. Therefore, there will be 2 driving forces when U-shaped seat 5 moves, and the closing of right handle is energy-saving.

(18) Of course, these are only preferred embodiment of the invention, and the patent scope of this invention shall not be confined by that. All applications using the instructions and drawings of the present invention with just simple modifications and equivalent structure changes shall be included in the scope of the patent protection of the present invention.
