Advantages of the present invention: The multifunctional wrench described in the present invention is suitable for the disassembly of most bolts or nuts, and does not need to adjust the wrench, and can be used directly, saving a lot of time, and has a good application prospect.
[0004] In order to pursue diversified functions, existing wrenches often destroy the structure of the wrench body to the extreme when used, which reduces its load-bearing capacity. Although it can adapt to various styles of nuts by opening multiple holes, its adaptability is still small due to the limited area of the main structure.
[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an integrated multifunctional wrench for mechanical processing and manufacturing is provided, in order to achieve the purpose of having more practical value. Summary of the invention

[0014] 1. Since a T-shaped rail groove is horizontally opened in the right side wall of the multifunctional base, the front end structure of the combination wrench is slidably built into the T-shaped rail groove, and a limit screw cap is vertically screwed at a position corresponding to the middle of the T-shaped rail groove on the front side wall of the multifunctional base. The combination wrench part can be slidably inserted in the T-shaped rail groove and the accommodating hole, which is convenient for combination. It can be used in the combined state or disassembled separately for use, and is suitable for a variety of environments.
[0015] 2. Since a locking block adapted to the sliding of the T-shaped rail groove is fixedly installed vertically forward at the end of the right half of the combination wrench, a locking slot hole adapted to the limiting screw nut is opened in the middle of the front end side wall of the locking block, and a screw head is provided at the left end of the bone wrench body through a sleeve, and the screw head is inserted into the accommodating hole. The bone wrench body can be used to operate a variety of nuts, and it can be used in two ways: detachable and combined. When disassembled for use, the screw head can also be used. One wrench is equivalent to multiple wrenches, and there will be no interference with each other during use.
