[0003] At present, when processing paper, a holding vehicle is needed to clamp and lift the stacked paper. However, the existing holding vehicle generally only clamps the paper by clamping arms on both sides when in use, and no supporting structure for the paper is provided. Since the stacked paper is heavy, after the paper is clamped, a large friction resistance is formed between the paper and the clamping arms, resulting in wrinkles or even damage to the paper close to the clamping arms, thereby causing waste of paper.

[0004] A paper processing and conveying trolley is proposed in the patent document with publication number CN216472096U. The device includes a carrying plate with an extension plate centrally constructed, a movable groove is centrally provided in the carrying plate and the extension plate, a No. 2 motor is centrally fixedly installed on the upper end surface of the extension plate, the No. 2 motor is connected to a threaded wire shaft rotatably installed in the movable groove through a motor shaft, a rectangular block is symmetrically threadedly installed on the outer edge surface of the threaded wire shaft, two rectangular blocks are symmetrically arranged, and a No. 2 clamping arm is fixedly connected to the side of the rectangular block away from the carrying plate, an adjustment groove is centrally provided on both sides of one side of the carrying plate, and a No. 1 motor is centrally fixedly installed on both sides of the carrying plate, the No. 1 motor is connected to a threaded wire rod rotatably installed in the adjusting groove through the motor shaft, the paper processing and conveying trolley has a reasonable structure, reduces the situation in which paper is easily wrinkled and damaged by clamping paper only by clamping arms on both sides, is conducive to reducing waste, and has strong practicality.

[0005] However, the device does not have relevant high-pressure hydraulic protection.
