[0040] Specifically, the workpiece to be bent is inserted into the inner side of the limiting plate 5 along the outside of the mounting block 1, and then the bending roller 4 is rotated along the positioning plate 3 to bend the workpiece. When bending, the elastic potential energy of the spring telescopic rod 7 is used to drive the fixing plate 8 and the rotating roller 10 thereon to move and rotate, and the workpiece is positioned by the rotating roller 10.

[0041] Referring to Figure 1 , Figure 2 and Figure 3 , the positioning mechanism 2 includes a bidirectional threaded rod 201. The bidirectional threaded rod 201 is rotatably connected inside the mounting block 1. Moving blocks 204 are threadedly connected to both the upper and lower sides of the outer wall of the bidirectional threaded rod 201.

[0042] Specifically, rotating the bidirectional threaded rod 201 can drive the moving block 204 and the moving plate 202 thereon to move, so as to drive the moving plate 202 and the connecting rod 206 thereon to move, and drive the rubber plate 203 to move up and down along the card slot 205, so as to facilitate the fixing of workpieces of different specifications.

[0043] Referring to Figure 1 , Figure 3 and Figure 4 , fixed blocks 23 are fixedly connected to the peripheries of the right ends of the mounting blocks 1.

[0044] Specifically, through the fixed blocks 23 and the brackets 22 thereon, the firmness of the fixation between the mounting blocks 1 and the positioning plates 3 can be improved. By rotating the torsion rod 17, it is convenient to drive the bending roller 4 to rotate. Through the grip 18, it is convenient to drive the torsion rod 17 to rotate. Through the engagement of the plug-in slots 19 and the plug-in blocks 20, the firmness of the fixation between the mounting blocks 1 and the positioning plates 3 can be improved through the connecting plate 21. At the same time, through the connecting plate 21, it is convenient to clamp the device through the workpiece.

[0045] Referring to Figure 2 , Figure 3 and Figure 4 , a mounting plate 13 is arranged on the front side of the limiting plate 5. Mounting grooves 14 are formed in the peripheries of the outer walls of the limiting plate 5, and the mounting plate 13 is engaged with the limiting plate 5 through the mounting grooves 14; a positioning groove 15 is formed in the front side of the mounting plate 13, and a slider 16 is fixedly connected to the inside of the positioning groove 15; a knob 24 is rotatably connected to the middle of the top of the mounting block 1, and the bottom of the knob 24 penetrates through the mounting block 1 and is fixedly connected to the bidirectional threaded rod 201;

[0046] Specifically, through the fixation of the mounting plate 13 and the mounting grooves 14, the firmness of the clamping of the workpiece by the limiting plate 5 can be improved. Through the slider 16 in the positioning groove 15 thereof, when the bending roller 4 rotates, the rotation of the limiting plate 5 can be prevented from being obstructed by the rotating roller 10 and the rotating roller 10 through the sliding of the slider 16.

[0047] Working principle: Before using the device, first insert the workpiece along the outside of the mounting block 1 into the inside of the limit plate 5, and then rotate the bending roller 4 to bend the workpiece. During the bending process, utilize the elastic potential energy of the spring telescopic rod 7 to drive the fixed plate 8 and the rotating roller 10 thereon to move and rotate, and position the workpiece with the rotating roller 10. At the same time, the elastic action of the positioning spring 11 causes the rotating plate 6 and the positioning roller 12 thereon to also start rotating. During the bending of the workpiece, the contact and interaction between the rotating roller 10 and the positioning roller 12 can help reduce and relieve the stress and damage to the workpiece during bending;

[0048] By rotating the bidirectional threaded rod 201, the moving block 204 and the moving plate 202 thereon are driven to move, thereby driving the connecting rod 206 and the rubber plate 203 thereon to move up and down along the card slot 205.
