Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2 The utility model provides a technical solution: a waste cardboard clamping tool, comprising a left frame 1 and a right frame 2, a fixed pedestal 3 is installed at the center of the top end of the left frame 1 and the right frame 2, the fixed pedestals 3 at the top ends of the two frames are connected by a telescopic rod 4, and ears 5 are welded on the left and right sides of the fixed pedestal 3, a slide groove 6 is arranged on the inner bottom surface of the left frame 1 and the right frame 2, a clamping plate 7 is slidably installed in the slide groove 6, a transverse axial screw nut mechanism is installed in the slide groove 6, the screw nut mechanism includes a screw 14 and a nut 15, wherein one end of the screw 14 in the screw nut mechanism passes through the clamping plate 7 and is rotatably connected to the inner wall of the slide groove 6 through a bearing, a rotating gear 8 is installed at the bottom of the outer surface of the left frame 1 and the right frame 2, and the other end of the screw 14 in the screw nut mechanism passes through the frame and is connected to the rotating gear 8;

[0016] The clamping plate 7 is provided with a plurality of rubber racks 9 with equal spacing from top to bottom. A first hand wheel 10 is rotatably mounted on the top surface of the left frame 1 and the right frame 2. A tooth is provided on the inner side of the first hand wheel 10. A lifting screw 11 is rotatably connected inside the first hand wheel 10. The bottom end of the lifting screw 11 passes through the frame and is connected to a pressing plate 12.

[0017] A second hand wheel 13 meshing with the rotating gear 8 is installed on the outer surface of the bottom of the left frame 1 and the right frame 2 .

[0018] The nut in the screw-nut mechanism is fixedly connected to the clamping plate 7.

[0019] The second hand wheel 13 drives the screw rod 14 to rotate in the slide groove 6 by rotating the gear 8 .

[0020] Working principle:

[0021] When using the present solution, firstly, one of the frames is manually held and stretched according to the length of the waste cardboard, and the left-right distance between the left frame 1 and the right frame 2 is adjusted by the telescopic rod 4, and then the left and right ends of the waste cardboard are respectively placed on the inner bottom surface of the frame;

[0022] Then manually rotate the second hand wheel 13, the outer surface of which has meshing teeth that match the rotating gear 8, so that the second hand wheel 13 drives the rotating gear 8 to rotate, so that the screw rod 14 can rotate in the slide groove 6. When the screw rod 14 rotates, its nut will move laterally on the screw rod 14. The nut and the clamping plate 7 in the screw rod nut mechanism are fixed structures, thereby driving the clamping plate 7 to move in the direction of the rotating gear 8. The multiple rubber racks 9 on the outer surface of the clamping plate 7 can be used to increase the friction with the waste cardboard. After the clamping plate 7 moves, one side of the waste cardboard is limited and resisted, and the other side of the waste cardboard is attached to the inner wall of the frame;

[0023] Then manually turn the first hand wheel 10. There is a rack matched with the lifting screw 11 on the inner wall of the annular hole of the first hand wheel 10. The first hand wheel 10 and the lifting screw 11 are threadedly connected. When the first hand wheel 10 is turned, the lifting screw 11 can be driven to move downward, and the waste cardboard in the frame can be pressed by the pressure plate 12 at the bottom, which can play a role in compacting the waste cardboard and facilitate the sorting, packaging and transportation of the waste cardboard. Lifting ears 5 are provided on the left frame 1 and the right frame 2, which are convenient for connection through ropes or manual lifting. The whole structure provides convenience for the recycling of waste cardboard.
