[0025] The mounting arm 2 is provided with a controllable mounting frame 4, and the mounting frame 4 is controlled to be lifted and lowered by an electric push rod 6 installed on the mounting arm 2. The housing of the electric push rod 6 is fixedly connected to the mounting arm 2, and the output rod of the electric push rod 6 penetrates the mounting arm 2 and is fixedly connected to the mounting frame 4. The lifting and lowering of the mounting frame 4 can be controlled by controlling the extension and retraction of the output rod of the electric push rod 6. An angle-adjustable inclined rod 5 is installed on the mounting frame 4, and a grinding layer is installed on the lower side of the inclined rod 5. When grinding is required, the output rod of the electric push rod 6 can be extended to make the inclined rod 5 descend until the grinding layer on the lower side of the inclined rod 5 fits with the surface to be trimmed of the grinding wheel. At this time, the control motor 3 is started, so that the grinding of the grinding wheel can be realized.

[0026] The motor 3 and the electric push rod 6 are respectively connected to an external power source through cables, and the start and stop of the motor 3 and the electric push rod 6 can be controlled by turning on and off the control circuit.

[0027] The mounting frame 4 is in the shape of a "┌" shape, and its lateral side walls are connected to the electric push rod 6, and the vertical side walls are connected to one end of the inclined rod 5. The vertical side walls of the mounting frame 4 are located above the center position of the base 1, and the angle of the inclined rod 5 can be adjusted by adjusting the height of the end of the inclined rod 5 away from the center position of the base 1. An adjusting portion for adjusting the angle of the inclined rod 5 is installed on the lateral side walls of the mounting frame 4, and the adjusting portion is located at the outer end of the inclined rod 5, that is, the end of the inclined rod 5 away from the center position of the base 1.
