Description

Technical Field

[0001] The utility model relates to the technical field of manual hardware tools, in particular to a split pin wrench. Background Art

[0002] Currently, the opening pliers available on the market are time-consuming and laborious to use. Summary of the invention

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned technology and to provide a split pin wrench which has reasonable design, is easy to manufacture and can be quickly split.

[0004] The technical scheme adopted by the utility model to solve the technical problem is: a split pin wrench, comprising a fixed handle, a movable handle, a slider, an A cone pin, a B cone pin, a C cone pin, a fixed shaft and a fastening screw, wherein the front end of the fixed handle is provided with an A positioning hole and a B positioning hole, the A cone pin is connected with the A positioning hole, the B cone pin is connected with the B positioning hole, the lower end of the slider is provided with a C positioning hole, the C cone pin is connected with the C positioning hole, the upper end of the slider is provided with a fastening screw hole, the fastening screw is connected with the fastening screw hole, the fixed handle and the movable handle are connected through the fixed shaft at the A fixed shaft hole and the B fixed shaft hole, and the utility model is characterized in that the front end of the fixed handle is provided with an A cone pin and a B cone pin, the movable handle is provided with a slider, the upper end of the slider is provided with a fastening screw to fix the slider, the lower end of the slider is provided with a C cone pin, when in use, the A cone pin is inserted into the closed end of the cotter pin, the B cone pin blocks the middle position of the cotter pin, the C cone pin first opens the long leg of the cotter pin open end, then the B cone pin is placed on the other side of the middle position of the cotter pin, the C cone pin then opens the short leg of the cotter pin open end, and finally the cotter pin is opened.

[0005] When splitting the cotter pin, insert the A cone pin into the closed end of the cotter pin, block the middle position of the cotter pin, first open the long leg of the cotter pin's open end with the C cone pin, then place the B cone pin on the other side of the middle position of the cotter pin, and then open the C cone pin's short leg at the open end of the cotter pin, and finally open the cotter pin.

[0006] In summary, the utility model provides a practical tool which is accurate, easy to operate and can quickly split cotter pins. The tool is very convenient to use and greatly reduces the labor intensity of the operator. BRIEF DESCRIPTION OF THE DRAWINGS
