A third transmission wheel 16 is rotatably connected to the front side of the moving block 1504.

[0034] The first transmission wheel 702 , the second transmission wheel 9 and the third transmission wheel 16 are sleeved with the same set of transmission belts 13 .

[0035] In this embodiment, the steel wire rope is passed between the two sets of working plate mechanisms 3, and then the hydraulic rod 5 is activated to adjust the position of the working plate mechanism 3 located on the upper side, and the steel wire rope is fixed between the two sets of fixed rollers 701 and the two sets of movable rollers 12, which can meet the needs of fixing steel wire ropes of different thicknesses;

[0036] The drive motor 4 is started to drive the shaft 7 to rotate, thereby driving the fixed roller 701 to rotate, and the shaft 7 drives the second transmission wheel 9 to rotate synchronously through the transmission belt 13 on the first transmission wheel 702, the second transmission wheel 9 drives the driving gear 10 to rotate, the driving gear 10 drives the driven gear 11 to rotate, thereby driving the moving roller 12 to rotate, and because the gear ratio of the driving gear 10 is greater than the gear ratio of the driven gear 11, the rotation speed of the driven gear 11 will be greater than the rotation speed of the driving gear 10, and then the rotation speed of the moving roller 12 is greater than the rotation speed of the fixed roller 701, so that the steel wire rope between the moving roller 12 and the fixed roller 701 is tensioned and straightened;

Since the length of the transmission belt 13 is fixed and the position of the first transmission wheel 702 is fixed, as the third transmission wheel 16 gradually moves away from the plate body 6, the transmission belt 13 will drive the slider 8 to slide along the slide hole 601 to the side close to the first transmission wheel 702 through the second transmission wheel 9, and compress and deform the connecting spring 14 to generate energy storage, thereby shortening the distance between the moving roller 12 and the fixed roller 701, meeting the straightening requirements for steel wire ropes of different lengths and increasing the applicability of the device.

[0038] Similarly, starting the push assembly drives the moving block 1504 to approach the plate body 6, and the energy released by the compression deformation of the connecting spring 14 drives the slider 8 to slide toward the side away from the first transmission wheel 702, thereby increasing the distance between the moving roller 12 and the fixed roller 701.

[0040] When the moving block 1504 is limited by the sliding hole 601 , starting the servo motor 1503 to drive the threaded screw 1502 to rotate will drive the moving block 1504 to move, thereby adjusting the use position of the third transmission wheel 16 .

[0041] Optionally, the slider 8 includes a first side block 801 and a second side block 802 that are movably connected, the first side block 801 and the second side block 802 are both slidably connected to the slide hole 601, a limit spring 803 is arranged between the first side block 801 and the second side block 802, one end of the limit spring 803 is fixedly connected to the first side block 801, and the other end is fixedly connected to the second side block 802, the moving roller 12 and the driven gear 11 are arranged on the first side block 801, the second transmission wheel 9 and the driving gear 10 are arranged on the second side block 802, and an electromagnet assembly is arranged at one end of the slide hole 601 away from the shaft 7;

Then, the servo motor 1503 is started to drive the threaded screw 1502 to rotate and drive the moving block 1504 and the third transmission wheel 16 away from the plate body 6. At this time, the transmission belt 13 drives the second side block 802 away from the first side block 801 through the second transmission wheel 9, and stretches the limit spring 803 to deform and generate energy storage;

[0047] As the first side block 801 and the second side block 802 move away from each other, the transmission teeth 1003 and the transmission teeth 1003 wheel are released from meshing relationship, and at this time, the electric push rod 1004 is started to push the connecting plate 1005 to move, and the connecting plate 1005 drives the sliding rod 1002 to slide on the transmission rod 1001, so that another set of transmission teeth 1003 with different gear ratios and the transmission teeth 1003 wheel are kept on the same horizontal plane;
