Detailed ways

The specific implementation, structure, features and functions of the puller of the quick release device according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

Please refer to Fig. 1, Fig. 2 and Fig. 3, the first embodiment of the puller of the quick release device of the present invention has a main body 10 and two reinforcing bodies 20, wherein:

The main body 10 is prolate and has a head 12 in the shape of a circular arc notch, and a body 13 for providing the pulling member of the utility model. The two sides of the main body 10 are respectively concave. A groove 11 is provided. In a preferred embodiment of the present invention, the body 10 is made of a plastic material, such as plastic material or light steel, so as to effectively reduce the weight of the triggering member.

Each reinforcing body 20 is made of rigid material, and is glued in the grooves 11 on both sides of the main body 10 respectively. 13 and slightly smaller than the fitting portion 23 of the body 10 body 13 . The cam portion 22 of each reinforcing body 20 is provided with an eccentric through hole 21 , so that the center of the through hole 21 has a maximum distance from the outer peripheral edge of the head of the cam portion 22 . Each reinforcing body 20 is embedded and glued in the groove 11 in a tightly fitting manner. In a preferred embodiment of the present invention, the reinforcing body 20 is made of rigid material, such as aluminum.

When the two reinforcing bodies 20 are respectively accommodated in the groove 11 of the main body 10 , a slot is formed between the cam portions 22 of the two reinforcing bodies 20 for passing through the C-shaped collar connected with the quick release device.

Since the body 10 made of plastic material is light in weight, the reinforcing body 20 made of rigid material is arranged in the grooves 11 on both sides of the body 10, so that the overall weight of the triggering member can be effectively reduced. And when the main body 10 is made of plastic material, the reinforcement body 20 on both sides can be directly coated to form the trigger during processing and molding. Therefore, the trigger of the present invention has the advantages of light weight and easy processing.

Please refer to FIG. 4 again, which is a plane cross-sectional view of the second embodiment of the puller of the quick release device of the present invention. The main body 10' of the present utility model can further form a flange 101 in the shape of covering the reinforcing body 20 on the two outer edges of the groove 11' accommodating the reinforcing body 20, so that the reinforcing body 20 will not separate from the main body. 10' drop in groove 11'.

Please refer to FIG. 5 , which is an exploded perspective view of the third embodiment of the trigger member of the quick release device of the present invention. In an embodiment, the utility model can be provided with a groove 11" on one side of the body 10", and the head of the body 10" is formed as a cam-shaped head 12" of the reinforcing body 20", and the head 12" An eccentric perforation is respectively formed on the top, which can also achieve the purpose of the utility model. The groove 11" on the body 10" is formed to the rear of the cam-shaped head 12".

Please refer to FIG. 6 , which is a schematic diagram of the use state of the trigger member of the quick release device of the present invention. When the trigger of the utility model is used with the quick release device, when the trigger is relatively close to the C-shaped collar of the quick release device, the trigger is from the center of the through hole 21 of the reinforcing body 20 to the head 22 The maximum distance between the puller and the C-ring of the quick-release device is relatively far away from the C-ring; the maximum distance from the through hole 21 to the head 22 of the puller is far away from the C-ring, so C-rings can be loosened.

The trigger part of the quick release device of the present utility model has the convenience of processing because the plastic material of the molding body 10 is light in weight and can be injection molded in large quantities; in addition, the metal reinforcing body 20 is embedded in the body 10, However, the required strength can be provided when using the wrench, so the overall weight of the wrench can be reduced, and it is convenient for processing and manufacturing.

The above are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any Those skilled in the art, without departing from the scope of the technical solution of the present utility model, can use the structure and technical content disclosed above to make some changes or modify equivalent embodiments with equivalent changes, but all without departing from the utility model The content of the new technical solution, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the utility model.
