Description

Hand tools that can automatically respond to card arrivals

technical field

The present invention relates to a hand tool, in particular to a hand tool which can have at least two socket parts on the same drive head which can be selectively socketed with a work object and which can be engaged correspondingly by itself.

Background technique

When workers work with hand tools, take a fixed wrench (torx wrench or open-end wrench) or a socket wrench (fixed or ratchet) as an example. When choosing a hand tool of appropriate size, usually do not use The measuring tool first measures the size specification of the work object (such as a screw head), and directly measures the approximate ruler of the work object by visual inspection, and then determines the size of the applicable hand tool. However, due to two similar It is easy to misjudge the size of the size, so it is difficult to directly and accurately select the correct size of the hand tool by visual inspection alone. Therefore, it is often time-consuming to select the hand tool because the size of the hand tool cannot be accurately determined during work.

Please refer to Fig. 10, it is a kind of existing hand tool, and it has a body 90, and has a drive head 91 at this body 90 one end, and this body 90 is provided with the sleeve 92 of several different sizes, for driving When a work object (not shown in the figure), can select the sleeve 92 of applicable dimension specification on this body 90 to be connected on this driving head 91 and drive this work object; The convenience of carrying sleeves 92 of various sizes and specifications with you, however, still has the problem of being unable to directly confirm the size as mentioned above, and when there are more sizes and specifications of each sleeve 92, the size of the main body 90 must be relatively increased in order to The required corresponding number of sleeves 92 are accommodated, but in this way, the volume of the wrench will be too large, which is not conducive to use when working in a narrow space.

In addition, there is also an existing wrench structure, as shown in FIG. 11 , which is a wrench drive head 91A with several sleeves 92A that are relatively movable and telescopic with different sizes. The size of the sleeve 92A is different, so as to achieve the purpose of being suitable for working objects of various sizes; and each sleeve 92A of the wrench with this structure can only be respectively socketed on a fixed-size working object, so when When the outer diameter of the working object is worn out through repeated disassembly, there will still be a situation where the sleeve 92A cannot engage with the working object; moreover, this kind of wrench structure cannot display the working object after being sleeved. Corresponding to the size specification of the socket part, therefore, in addition to the need to test the fit separately, which is quite troublesome and time-consuming, it will not be conducive to future replacement due to the inability to quickly know the actual outer diameter of the working object Work.
