[0030] Reference Figure 1-5 As shown, the clamping device 6 includes two U-shaped plates 61, one of which is fixedly connected to the base 1, and the other is fixedly connected to the bottom of the movable plate 4. A screw 62 is threadedly connected to the surface of the U-shaped plate 61, and one end of the screw 62 located outside the U-shaped plate 61 is fixedly connected to a pad 63, and one end of the screw 62 away from the pad 63 is rotatably connected to a clamping plate 64, and a first rubber pad 65 is fixedly connected to the side of the clamping plate 64 away from the screw 62, and a second rubber pad 66 is fixedly connected to the inner wall of the U-shaped plate 61. Before the bran paper needs to be stretched, first, the two ends of the bran paper are respectively inserted into the interior of the two U-shaped plates 61, and then the pad 63 is rotated, and the pad 63 rotates with the screw 62, and the screw 62 moves the clamp 64 and the first rubber pad 65 to the other side of the U-shaped plate 61, and finally the first rubber pad 65 and the second rubber pad 66 on the U-shaped plate 61 squeeze the bran paper together, thereby achieving the effect of fixing the bran paper, and then the cylinder 3 on the bracket 2 is opened, and the cylinder 3 moves the movable plate 4 in the movable groove 5, and the bran paper is stretched. At this time, the first rubber pad 65 and the second rubber pad 66 increase the friction between the clamp and the bran paper to prevent the bran paper from sliding, and the effect of fixing the bran paper is achieved through the clamping device 6, thereby preventing the bran paper and the clamp from sliding, thereby improving the practicability of the stretching equipment.
[0031] Reference Figure 1-5As shown, the cross-section of the first rubber pad 65 and the second rubber pad 66 is serrated, and the serrations on the first rubber pad 65 and the second rubber pad 66 are interlaced. The first rubber pad 65 and the second rubber pad 66 clamp the leather bran paper inside the serrated groove, increase the contact area between the rubber pad and the leather bran paper, and further improve the anti-slip effect of the leather bran paper. The upper surface of the clamping plate 64 is fixedly connected with a fixed plate 67, and the surface of the fixed plate 67 is slidably provided with a limit plate 68, and the two ends of the limit plate 68 are fixedly connected to the inner wall of the U-shaped plate 61.

Both arms of the U-shaped plate 61 are fixedly connected with an inclined plate 69, and the two inclined plates 69 are symmetrically arranged. By setting two inclined plates 69, it is convenient for the staff to place the leather bran paper inside the U-shaped plate 61, which brings convenience to the staff.
[0032] Reference Figure 1-5 As shown, the surface of the pad 63 is provided with an auxiliary device 7, and the auxiliary device 7 includes a clamping groove 72, which is provided on the side of the pad 63 away from the screw 62, and the pad 63 is slidably connected with the clamping plate 71 by means of the clamping groove 72. When the pad 63 and the screw 62 need to be moved, the clamping plate 71 is firstly moved out of the clamping groove 72 of the pad 63, and then the clamping plate 71 is rotated, and the clamping plate 71 moves with the pad 63, and the clamping plate 71 increases the rotation force arm of the pad 63, thereby facilitating the staff to rotate the pad 63. By increasing the rotation force arm of the pad 63 through the auxiliary device 7, it is convenient for the staff to rotate the pad 63 with less force, which brings convenience to the staff.

By moving the slider 73 in the slide groove 74, the maximum displacement of the card plate 71 is limited to prevent the card plate 71 from being separated from the pad 63. A control block 77 is fixedly connected to the surface of the card plate 71, and the surface of the control block 77 is provided with anti-slip grooves. By setting the control block 77, the contact area between the staff's hand and the card plate 71 is increased, so that it is convenient for the staff to rotate the card plate 71, which brings convenience to the staff. A first magnet 75 is fixedly connected to the surface of the card plate 71, and a second magnet 76 is fixedly connected to the surface of the pad 63, and the first magnet 75 and the second magnet 76 attract each other. When the card plate 71 is not in use, the card plate 71 automatically enters the interior of the pad 63 under the mutual attraction of the first magnet 75 and the second magnet 76, so that the card plate 71 is convenient to hide.
[0034] Working principle: before the bran paper needs to be stretched, first insert the two ends of the bran paper into the inside of the two U-shaped plates 61 respectively. At this time, the control block 77 is used to move the card plate 71 out of the card slot 72 of the pad 63 to increase the turning force arm of the pad 63. Then the control block 77 is rotated, and the control block 77 rotates with the pad 63, and the pad 63 rotates with the screw 62. The screw 62 moves the clamping plate 64 and the first rubber pad 65 to the other side of the U-shaped plate 61. Finally, the first rubber pad 65 and the second rubber pad 66 on the U-shaped plate 61 squeeze the bran paper together to achieve the effect of fixing the bran paper. The staff loosens the control block 77, and the card plate 71 is in the first magnet 7 5 and the second magnet 76, the card plate 71 automatically enters the interior of the pad 63, which is convenient for hiding the card plate 71. The auxiliary device 7 increases the turning force arm of the pad 63, which is convenient for the staff to rotate the pad 63 with a smaller force, bringing convenience to the staff. Finally, the cylinder 3 on the bracket 2 is turned on, and the cylinder 3 moves with the moving plate 4 in the moving groove 5, and the bran paper is stretched. At this time, the first rubber pad 65 and the second rubber pad 66 increase the friction between the clamp and the bran paper to prevent the bran paper from sliding. The clamping device 6 achieves the effect of fixing the bran paper, preventing the bran paper and the clamp from sliding, and improving the practicality of the stretching equipment.
