Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that the following descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any modifications or changes based on the spirit of the present invention should still be included in the present invention. within the scope of the invention.

[0016] The present invention is a hexagonal wrench that can handle chamfered screws, please refer to Figure 1 and Figure 2, it is composed of a sleeve 10 and a sleeve shaft 20, wherein the sleeve 10 can be used by the user to use a ratchet Type socket wrench or open-ended wrench or ring wrench etc., the present invention is mainly described with the ratchet type socket wrench as an embodiment.

[0017] Regarding the detailed structure of the preferred embodiment of the present invention, as shown in Fig. 1...

Abstract

The invention relates to a hex wrench dealing inverted screw, particularly a hex wrench with simple structure and high clamping stability, with one sleeve barrel end inserted into a matching shaft whose edge side forming into a semi circular cross section containing arc slot with a pair of clamps shoring against an elastic part at one side that is tilt up, protruding the edge of the matching shaft. When the matching shaft embedded into the inverted screw hex hole, it can use the protruded clamp stopping the falling of the corresponding angle of the hex hole to prevent the relative slippery to improve the clamping result in order to assist the effective drawing back of the inverted screw.

Description

technical field [0001] The invention relates to a wrench, in particular to a hexagonal wrench for handling chamfered screws. Background technique [0002] A screw is a part used to combine and fix objects. According to the needs of the environment and different needs, the screw head can be divided into a hexagonal head for jaws or sleeves or an inner hexagonal hole for a hexagonal wrench. Among them, the inner hexagonal If the hole-type screw is repeatedly rotated for a long time or due to factors such as excessive reaction force, the corners of the inner hexagon hole are curved and chamfered due to wear, which will cause the problem that the general hexagonal wrench cannot withdraw from the screw. Because it is not like a screw with a hexagonal head, it is designed with a variety of tools that can be withdrawn directly, such as the "impact driver and tie removal device" of Taiwan Patent Publication No. I250922, the "forced loosening device" of the Publication No. 584587 Sc...
