[0023] Please refer to Figs. 1-3In the embodiment, the anti-skid pads 103 are installed on the outer side of the device shell 1, and the mounting grooves for installing the anti-skid pads 103 are formed on the outer side of the device shell 1. The presence of the anti-skid pads 103 significantly increases the friction between the hands and the device shell 1, which can effectively reduce the risk of safety accidents caused by accidental sliding of the device in dry or humid working environments. The control button 104 is installed on the top end of the device shell 1 near the edge of one end. The mounting groove for installing the control button 104 is formed through the top end of the device shell 1. The control button 104 is installed on the top end of the device shell 1 near the edge of one end, which conforms to the natural placement and operation of the fingers when the operator holds the device. During use, the operator does not need to significantly change the hand holding posture or perform unnatural actions such as excessive stretching and bending of the fingers to easily reach the control button 104.

[0024] Please refer to Figs. 1-3 In the embodiment, the handle 101 is installed at the bottom end of the device shell 1. The battery compartment 107 is formed at the bottom end of the handle 101 near the edge of one end of the control button 104. The battery cover plate is installed in the battery compartment 107. The auxiliary illuminating lamp 102 is installed at the center of the side of the handle 101 near the battery compartment 107. The auxiliary illuminating lamp 102 installed at the center of the side of the handle 101 near the battery compartment 107 plays an important role in the door and window welding point polishing operation. When the working environment is relatively dark or some parts of the door and window are in the shadow area, the auxiliary illuminating lamp 102 can provide local illumination. The mounting hole 108 for installing the polishing assembly is formed at the front end of the device shell 1.
