A rotating shaft 4 is rotatably connected inside the protective frame 1. A first gear 5 that meshes with the first rack 3 is fixedly connected to the outside of the rotating shaft 4. A relief groove is formed inside the protective frame 1. The upper and lower walls of the relief groove are both slidably connected with a connecting plate 6. Second racks 7 are fixedly connected to the opposite sides of the two connecting plates 6. A second gear 8 that is located inside the relief groove and meshes with the two second racks 7 is fixedly connected to the outside of the rotating shaft 4. Extension plates 9 are fixedly connected to the right sides of the two connecting plates 6. Mounting plates 10 are fixedly connected to the right sides of the two extension plates 9 through fasteners. Clamping devices 11 are arranged on the right sides of the two mounting plates 10. The inside of the two clamping devices 11 is connected to a sandpaper 12.

[0028] Among them, the moving device 2 includes a motor 21 fixedly connected to the inside of the protective frame 1, a reciprocating screw 22 fixedly connected to the inside of the protective frame 1 for rotation is provided on the outer side of the output shaft of the motor 21, a transmission block 23 fixedly connected to the first rack 3 is provided on the outer side of the reciprocating screw 22 through a threaded transmission, and a limit rod 24 slidably connected to the transmission block 23 is fixedly connected to the inside of the protective frame 1.

[0029] In this embodiment, during actual use, the start of the motor 21 will drive the reciprocating screw 22 to rotate, and the transmission block 23 will move under the action of the thread, and its moving direction will be stabilized under the action of the limit rod 24.

[0030] The upper and lower walls of the inner part of the clearance groove are both provided with sliding grooves, and the opposite sides of the two connecting plates 6 are fixedly connected with sliding plates 13 which are slidably connected to the two sliding grooves respectively.

[0031] In this embodiment, during actual use, when the two connecting plates 6 are moving, the slide plate 13 will slide in the two slide grooves, and the slide grooves provide movement space for the slide plate 13 while limiting its movement direction.

[0032] The two extension plates 9 are provided with a plurality of first threaded holes distributed vertically, and the two mounting plates 10 are threadedly connected with first bolts 14 respectively threadedly connected to the first threaded holes.

[0033] In this embodiment, during actual use, the fixed position of the mounting plate 10 on the extension plate 9 can be changed by connecting the first bolt 14 with the first threaded holes at different height positions, thereby changing the relative distance between the two mounting plates 10 and even changing the relative distance between the two sets of clamping devices 11.

[0034] Among them, the two clamping devices 11 include a first fixing plate 111 fixedly connected to the right side of the two mounting plates 10 respectively, and the opposite sides of the two first fixing plates 111 are fixedly connected to the second fixing plates 112 by fasteners, and the inner sides of the two first fixing plates 111 and the two second fixing plates 112 are provided with wavy patterns.

[0035] In this embodiment, in actual use, the two fixing plates can clamp and fix the sandpaper 12, and the corrugated arrangement makes the fixation of the sandpaper 12 by the two fixing plates more stable.

[0036] A plurality of second threaded holes are formed inside the two first fixing plates 111 and the two second fixing plates 112 , and the second bolts 15 are threadedly connected inside the plurality of second threaded holes.

[0037] In this embodiment, during actual use, the docking of the second threaded hole and the second bolt 15 enables the two first fixing plates 111 to be fixedly connected to the two second fixing plates 112 respectively. The fixing of the second bolt 15 makes the sandpaper 12 not easily fall off during grinding.

[0038] Working principle:

[0039] First, according to the thickness of the door and window frame, adjust the relative positions of the two mounting plates 10 through the first bolt 14. Then, bypass the door and window frame with the sandpaper 12 and fix the sandpaper 12 by connecting the second bolt 15 with the second threaded hole. Start the motor 21. The reciprocating movement of the first rack 3 will drive the first gear 5 to rotate back and forth, so that the rotating shaft 4 drives the second gear 8 to rotate back and forth. At this time, the two connecting plates 6 will move forward and backward under the limitation of the sliding groove, and the sandpaper 12 will grind the inner side of the door and window frame back and forth. The soft sandpaper 12 just fits the corner arc and the rear side of the door and window frame. At this time, the position of the sandpaper 12 for grinding can be changed by manually moving the door and window frame or by using an electric device such as a push rod. The grinding position can be changed by manually or electrically rotating the door and window frame. The sandpaper 12 can be replaced or the door and window frame can be removed by disassembling the second bolt 15.
