Invention Description: TECHNICAL FIELD The present invention relates to the technical field of hand tools, and more particularly to a sleeve for a convenient disassembly tool head which is simple in structure and can be made in a low cost. [Prior Art] Taiwan Patent Publication No. 433121 discloses a conventionally detachable tool head. The utility model is provided with a U-shaped elastically contractible and enlarged pressing body in the positioning groove of the head end of the shank for clamping the tool head to prevent the tool head from being detached when the tool head is inserted into the positioning groove. However, it is very laborious to apply the tool head to the positioning groove by applying a force greater than the clamping force of the pressing body. In particular, the general part of the tool head that protrudes outside the positioning groove is a sharp-edged cross-head, a screwdriver or an awl. Therefore, when the force is pulled out, the force is removed. In the case of a very sharp knife, the part of the tool head that protrudes outside the positioning groove is pulled out. Moreover, after the pressing body is used for a period of time, it is prone to elastic fatigue and the function of holding the tool head is lost. " . Bay Patent Publication Nos. 334,895 and 461,368 each show a sleeve structure of a conventional removable tool head. The use of the control sleeve, c 1352650 • buckle and spring and other components to achieve the structure of the guard in the sleeve or released from the sleeve, the system is very complicated and the parts are more The cost of assembly and assembly has increased significantly, and the overall volume is also large.

The fixing portion 31 is annular and coupled to the rod wall of the driving rod 20. The embedding portion 32 is elastically stretchable. The positioning hole 22 of the driving rod 20 is inserted into the fitting groove 11 of the tool head 1. The force applying section 33 is connected to the fixing section 31 and the insertion section 32 and protrudes from one side of the driving rod 20. The manner in which the fixing portion 31 is coupled to the driving rod 20 can be screwed to the screw, the nailing or the welding, etc., which is not described again. In this embodiment, the urging section is bent obliquely upward by the side of the fixing section 31 along the outer wall of the driving rod 2, and then horizontally bent above the positioning hole 22 to make it convenient. The user applies force to pull it outward from the driving rod 20 - the side of the insertion portion 32 extends downward from the end of the force applying portion 33 above the positioning hole 22 into the positioning hole 22, and the insertion portion 32 is caused. One side is embedded in one side of the slot 11 of the tool head 1. The third and fourth figures show that when the joint section 10 of the tool head 1 is inserted into the polygonal hole 21 of the drive rod 20, the elastic member 3 is subjected to the joint section of the tool head by the insert section 32. Pushing and swinging an angle outward. Until the coupling section 1 is inserted into the polygonal hole 21 to a certain depth, the elastic member 30 is returned to the original position by its own elastic force, and the insertion section 32 is embedded in the insertion groove 11 of the coupling section 1 In order to prevent the tool head 1 from easily coming off the polygonal hole 21. On the contrary, when the user pulls the urging portion 33 of the elastic member 3 向外 outward from the side of the driving rod 20, the embedding portion 32 is separated from the slot 11 ′ on the coupling portion 10, so that the user can easily The tool head 分离 is separated by the drive rod 20. The fifth and sixth figures are the second aspect of the elastic member 3 of the present invention. The joint section 1 of the tool head cymbal referred to in the figure has a plurality of circular recesses 11. The clamping hole 22 is a circular hole which is opened to the polygonal hole 21 by the driving rod 2 〇 sidewall. The urging section 33 of the elastic member 3 is bent obliquely upward by the side of the fixed section 31 along the outer wall of the driving rod 2, and then horizontally bent above the positioning hole 22, the embedding section 32 is bent downwardly along the outer wall of the driving rod 2〇 by the force applying section 33 and then inserted into the positioning hole 22 horizontally to be inserted into the fitting groove 1 of the tool head 1 in. The seventh drawing is a third aspect of the elastic member 3 of the present invention. The force applying section 33 indicated in the figure is bent obliquely from the side of the fixing section 31, and then horizontally bent to the upper side of the positioning hole 22. The shackle #3 is extended from the urging section 3 3 to the positioning hole 22, and then extends downward into the positioning hole 22, and the side of the insertion section 32 is embedded in the tool head i The side is embedded in the slot u. The eighth figure is a fourth aspect of the elastic member 30 of the present invention. The force applying section 33 indicated in the figure is bent obliquely upward by an angle from the side of the fixing section 31, and then horizontally bent to the upper side of the positioning hole 22. The insertion section 32 extends downward from the force applying section 3 3 to the outside of the positioning hole 2 2 , and then is horizontally bent and inserted into the positioning hole 22 so that the end portion thereof is embedded in the slot 11 of the tool head 1 . in. From the above description, it can be understood that the sleeve structure of the present invention can not only facilitate the quick and easy removal of the guard head, but also has a simple structure and a relatively simple assembly and assembly, and can greatly reduce the manufacturing cost, and the whole 1352650 body. The volume is not large. In any case, anyone can obtain sufficient teaching from the description of the above examples and understand that the present invention does have industrial applicability. Further, the same technique as the present invention is not seen, so the present invention is novel. Further, the technique similar to the present invention is not seen, so the present invention is advanced. Thus, the present invention complies with the requirements of the invention patent and submits an application in accordance with the law.
