[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model moves the device to the shovel teeth so that the first sleeve is sleeved on the outside of the pin. After the device is fixed, the electric push rod drives the knocking block to knock the pin to remove the shovel teeth, which saves effort and avoids the force rebounding to the user's hands to make the hands feel sore.

[0013] 2. The utility model fixes the device on the ground by means of a brake roller and a stop plate, thereby preventing the device from shaking significantly during operation and thus affecting the use of the device. In addition, the height of the first sleeve can be adjusted by rotating the first bolt, thereby better adapting to shovel teeth at different heights. BRIEF DESCRIPTION OF THE DRAWINGS
