The top of the base plate 1 is provided with a rotating assembly, which is used to realize the rotating adjustment function of the specific part of the tool. The rotating assembly includes a first motor 10 fixedly connected with the top of the base plate 1, which serves as a power source to provide power for the operation of the whole rotating assembly, and its output end rotates after starting. The output end of the first motor 10 is fixedly connected with a first worm 11, which rotates under the driving of the output end of the first motor 10, and transmits power through the worm transmission principle. The top of the base plate 1 is fixedly connected with a support frame 2, which is used to support and fix other components, and ensure the stability of the installation position.
