The lower end of the edge grinding mechanism 2 is fixedly connected to the upper end of the base plate 1, and the upper inner wall of the base plate 1 is embedded and connected with the outer wall of the movable groove 3.

[0027] like Figure 2As shown, the edge grinding mechanism 2 includes a fixed plate 21, the lower end of the fixed plate 21 is fixedly connected to the upper end of the base plate 1, an electric push rod 22 is arranged on the outer side of the fixed plate 21, a mobile frame 23 is arranged at the telescopic end of the electric push rod 22, a lifting plate 24 is slidably connected to the inner wall of the mobile frame 23, a screw 25 is threadedly connected to the inner wall of the lifting plate 24, a guide rod 26 is slidably connected to one side of the inner side of the lifting plate 24, a motor 27 is fixedly connected to one side of the lifting plate 24, a rotating rod 28 is fixedly connected to the transmission end of the motor 27, and a grinding wheel 29 is fixedly sleeved on the outer wall of the rotating rod 28;

[0028] The outer side of the fixed plate 21 is detachably connected to the inner side of the electric push rod 22, and the telescopic end of the electric push rod 22 is fixedly connected to one side of the moving frame 23;

[0029] The outer surface of the screw rod 25 is provided with symmetrical threads which match with the inner wall threads of the two corresponding lifting plates 24 .

[0030] As can be seen from the above, a pulley is fixedly connected to the bottom of the movable frame 23. The provision of the pulley is beneficial to the stability of the movable frame when it moves, thereby preventing deviation during the edging process.
