[0011] In the figure, the present utility model is provided with a pressure roller device 3. One end of the pressure roller device 3 is rotatably connected to one end of the rotating bracket 2, and the other end of the rotating bracket 2 is hinged to the locking device 1. A counterweight device 4 is installed on the pressure roller device 3; the locking device 1 includes a locking handle 1-1, a locking bolt 1-2, and a locking nut 1-3. The locking handle 1-1 is welded to the locking bolt 1-2, and the locking nut 1-3 is welded to the rotating bracket 2. By rotating the locking handle 1-1, the rotating bracket 2 can be fixed to the equipment to realize the positioning function of the rotating bracket 2; the rotating bracket 2 includes a rotating ring 2-1 and side plates 2-2. The rotating ring 2-1 is sleeved on the output shaft of the equipment, and the locking nut 1-3 is welded on one side of the rotating ring 2-1. The side plates 2-2 are welded on both sides of the rotating ring 2-1, and the lower ends of the side plates 2-2 are provided with holes to connect the pressure roller device 3; the pressure roller device 3 includes a rotating bearing 3-1, a pin shaft 3-2, a pressure roller support plate 3-3, a lock hook 3-4, a pressure roller shaft 3-5, a pressure roller 3-6, a pressure roller set screw 3-7, and a fixed rope 3-8. The rotating bearing 3-1 is fixed between the side plates 2-2 by the pin shaft 3-2. One end of the pressure roller support plate 3-3 is connected to the rotating bearing 3-1, and free rotation can be realized through the rotation of the rotating bearing 3-1. The pressure roller shaft 3-5 is fixed to the other end of the pressure roller support plate 3-3, and the pressure roller 3-6 is installed on the pressure roller shaft 3-5 for free rotation. A pressure roller set screw 3-7 is installed on the pressure roller 3-6. After the pressure roller set screw 3-7 is tightened, the pressure roller 3-6 can be prevented from moving and shifting. A lock hook 3-4 is welded on the pressure roller support plate 3-3. The lock hook 3-4 is connected to one end of the fixed rope 3-8, and the other end of the fixed rope 3-8 is fixed to the output shaft of the equipment. When the pressure roller device 3 is not operating, the fixed rope 3-8 pulls the lock hook 3-4 to lift the pressure roller device 3; the counterweight device 4 includes a counterweight block 4-1 and a baffle 4-2. The counterweight block 4-1 is sleeved on the pressure roller support plate 3-3, and baffles 4-2 are welded above and below the pressure roller support plate 3-3 to prevent the counterweight block 4-1 from shifting.
