[0026] Specifically, the screw rod 12 is rotated by turning the handle, so that the frame 4 at the right end is driven, and then it is displaced under the drive of the screw rod 12, and at the same time it is limited by the slide bar 3 to prevent it from rotating after being driven by the screw rod 12, and the distance between the two frames 4 is adjusted to adapt to the length of the material. The interior of the limit frame 9 corresponds to the shape of the bottom end of the mobile frame 12, and can limit the bottom end of the mobile frame 12 to prevent the mobile frame 12 from rotating under the drive of the screw rod 2 10. Through the drive of the motor 2 11, the screw rod 2 10 will rotate and drive the mobile frame 12 to move to adjust the grinding position. At the same time, through the push of the bottom driving end of the electric push rod 13, the electric grinding head 14 will abut against the surface of the material for grinding.

[0027] Two turntables 5 are located on the side close to the two frames 4, one side of the turntable 5 is connected to the frame 4, and the other side of the turntable 5 is slidably connected to two clamping members 8. The inside of the turntable 5 is rotatably connected to a bidirectional screw 7, one end of the turntable 5 is threadedly connected to the outer wall of the bidirectional screw 7, and the other side of the two turntables 5 is provided with anti-slip protrusions. The driving end of the motor 1 6 is fixedly connected to the left middle end of the left turntable 5, and one end of the bidirectional screw 7 passes through the outer wall of the turntable 5 and is fixedly connected to a rotating bolt;

[0028] Specifically, the bidirectional screw 7 is rotated by a rotating bolt, so that the two clamping members 8 connected to the bidirectional screw 7 move toward each other, and then the two ends of the material placed on the side close to the two turntables 5 are clamped and fixed, and the stability of the clamping is further increased by cooperating with the rubber anti-slip protrusions. Driven by the driving end of the motor 6, the driven turntable 5 at the left end will drive the material to rotate, and then the turntable 5 at the other end of the material will rotate synchronously, so as to adjust the fine grinding angle of the material, so that there is no need to manually adjust the angle, which improves the work efficiency.

[0029] A through slot is provided at the middle end of the base 1, a suction fan 15 is installed at the bottom end of the inner wall of the through slot, a screen 17 is provided on the top side of the screen 16 located on the top side of the suction fan 15, the outer wall of the screen 16 is fixedly connected to the inner wall of the through slot, the left and right ends of the screen 17 are fixedly connected with ear plates 18, the left and right sides of the top of the through slot are provided with limiting slots, the ear plates 18 are located inside the limiting slots, and the top side of the ear plates 18 is fixedly connected with a lifting handle;

[0030] Specifically, the suction fan 15 can generate attraction through the air inlet on the top side, through the screen 16 and the screen 2 17, so that the debris generated by grinding is adsorbed on the screen 2 17. Since the sieve holes on the screen 16 and the screen 2 17 are staggered with each other, the debris is double-blocked, thereby preventing the debris from passing through the screen and accumulating on the suction fan 15, thereby ensuring the normal operation of the suction fan 15. The ear plate 18 stuck in the limit groove can be lifted together with the screen 2 17 by lifting the handle, thereby recovering the grinding debris accumulated on the screen plate 2.

[0031] Working principle: Before grinding, the material needs to be fixed, and the screw rod 2 is rotated by turning the handle, so that the frame 4 at the right end is driven, and then it moves under the drive of the screw rod 2, and the distance between the two frames 4 is adjusted to adapt to the length of the material. Then the material is placed between the two clamps 8, and the two-way screw rod 7 is rotated by the rotating bolt, so that the two clamps 8 connected to the two-way screw rod 7 move toward each other, and then the two ends of the material placed on the side close to the two turntables 5 are clamped and fixed. Then start grinding, through the push of the bottom driving end of the electric push rod 13, the electric grinding head 14 will abut against the surface of the material for grinding. Under the drive of the motor 11, the screw rod 10 will rotate and drive the moving frame 12 to move to adjust the grinding position. When the grinding angle needs to be adjusted, the left end driven turntable 5 will drive the material to rotate under the drive of the motor 6, and then the turntable 5 at the other end of the material will rotate synchronously, so as to adjust the fine grinding angle of the material and the debris generated during grinding. The waste material can be sucked onto the screen 2 17 by the suction fan 15 through the air inlet on the top side and through the screen 1 16 and the screen 2 17 to generate suction. Since the sieve holes on the screen 1 16 and the screen 2 17 are staggered with each other, a double layer of blocking is performed on the debris, thereby preventing the debris from passing through the screen and accumulating on the suction fan 15, thereby ensuring the normal operation of the suction fan 15. The ear plate 18 stuck in the limit groove can be lifted together with the screen 2 17 by lifting the handle, thereby recovering the grinding debris accumulated on the screen plate 2.
