DETAILED DESCRIPTION

[0020] With reference to FIGS. 1-5, a handle structure of a trolley according to a first embodiment of the present invention comprises: two grips 10 symmetrically mounted on a trolley 20, and the trolley 20 includes a holder 21 configured to hold objects, at least one rack 22 connected on a side of the holder 21, and multiple rollers 23 fixed on a bottom of the holder 21, wherein the at least one rack 22 includes two columns 221 spaced from each other and extending uprightly, a cross-section of a respective one column 221 is in a D shape, and a respective one grip 10 includes a first fixing portion 11, a second fixing portion 12, and a body 13.

[0021] The first fixing portion 11 is a sleeve with a D-shaped cross-section and is configured to be fitted on a top of the respective one column 221, wherein the first fixing portion 11 of the respective one grip 10 is screwed with the trolley 20 by using at least one screw element 14.

[0022] The second fixing portion 12 is a sleeve with a D-shaped cross-section and is configured to be fitted on the top of the respective one column 221 and located below a bottom of the first fixing portion 11, wherein the second fixing portion 12 of the respective one grip 10 is screwed with the trolley 20 by using the at least one screw element 14, and the first fixing portion 11 and the second fixing portion 12 are on an axial line A1.

[0023] The body 13 is a hollowly circular tube and is defined between the first fixing portion 11 and the second fixing portion 12, wherein a first end of the body 13 is connected with an outer side of the first fixing portion 11, and a second end of the body 13 is connected with a rear side of the second fixing portion 12. The body 13 includes a first extending portion 131, a first connection portion 132, a second extending portion 133, a second connection portion 134, and a third extending portion 135. In this embodiment, the first extending portion 131 extends outward from the first fixing portion 11, the first connection portion 132 extends from the first extending portion 131, the second extending portion 133 extends from the first connection portion 132, the second connection portion 134 extends downward from the second extending portion 133, and the third extending portion 135 extends downward from the second connection portion 134, wherein the third extending portion 135 is connected with the second fixing portion 12, the first extending portion 131 and the second extending portion 133 are horizontal, the third extending portion 135 is inclined, and the first connection portion 132 and the second connection portion 134 are curved, wherein an angle of the second portion 134 is more than an angle of the first connection portion 132, a connection position of the body 13 and the first fixing portion 11 is not different from a connection position of the body 13 and the second fixing portion 12, a connection direction of an end of the body 13 and the first fixing portion 11 is different from a connection direction of the other end of the body 13 and the second fixing portion 12, an offset angle is defined between the first extending portion 131 and the axial line A1 with respect to the third extending portion 135 and the axial line A1, and the offset angle is within 30 degrees to 135 degrees. Preferably, the offset angle is within 65 degrees to 85 degrees.

[0024] Thereby, the handle structure of the present invention is configured to have various changes of angles and heights of the respective one grip by way of the first extending portion 131, the first connection portion 132, the second extending portion 133, the second connection portion 134 and the third extending portion 135 based on a height and a desired holding position of a user, hence the user pushes or pulls the trolley 20 by gripping the body 13 on a desired angle and height.

[0025] Referring to FIG. 6, when the trolley 20 is placed on a ground, the second connection portion 134 of the body 13 abuts against the ground to support and erect the trolley 20.

[0026] As shown in FIG. 7, a difference of a second embodiment is that the first embodiment comprises the first fixing portion 11 and the second fixing portion 12 being located on a tube A2, wherein the first fixing portion 11 and the second fixing portion 12 are one-piece formed.

[0027] As illustrated in FIGS. 8 and 9, a difference of a third embodiment from that of the second embodiment comprises: the body 13 including a first spaced section 13A and a second section 13B which are separated on a middle portion of the body 13, wherein the first spaced section 13A is connected with the first fixing portion 11, the second spaced section 13B is connected with the second fixing portion 12, and the middle portion of the body 13 separated from the first spaced section 13A and the second spaced section 13B are cut flatly.

[0028] Therefore, the handle structure of the trolley has the following advantages:

[0029] The body 13 includes a first extending portion 131, the first connection portion 132, the second extending portion 133, the second connection portion 134, and the third extending portion 135 so as to have the various changes of the angles and heights of the two grips 10 based on the height and the desired holding position of the user, and the user pushes or pulls the trolley 20 by gripping the body 13 on the desired angle and height easily.

[0030] While the first embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. The scope of the claims should not be limited by the first embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
