However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

An electric telescopic rod 5 is arranged on the top of the fixed frame 1, and the telescopic end of the electric telescopic rod 5 slides through the top of the fixed frame 1, and the telescopic end of the electric telescopic rod 5 is fixedly connected with a connecting rod 8, and the bottom of the connecting rod 8 is fixedly connected with a connecting frame 4, and a pressure roller 3 is rotatably connected between the inner surface walls of the connecting frame 4, and a plurality of connecting columns 209 are equidistantly fixedly connected to the inner surface of the fixed ring block 202, and the outer surfaces of the plurality of connecting columns 209 are all fixedly connected to the outer surface of the mounting roller 201, and the outer surfaces on both sides of the mounting roller 201 respectively penetrate the outer surfaces on both sides of the fixed frame 1, and the mounting roller 201 is rotatably connected to the fixed frame 1.

[0025] The effect achieved by the entire embodiment 1 is that when the steel strip limiting component of the longitudinal shearing machine is adjusted, the motor 208 is started, and rectangular grooves are symmetrically opened on the outer surface of the mounting block 210 on which the motor 208 is installed. Battery packs are arranged in the two rectangular grooves to power the motor 208. When the output end of the motor 208 is working, it will drive the bidirectional threaded rod 206 to rotate forward and reversely in another mounting block 210. The multiple movable ring blocks 203 are set as multiple groups, and two movable ring blocks 203 are a group. Under the rotation of the bidirectional threaded rod 206, they will move toward or oppositely along the outer surface of the fixed rod 207. When the multiple groups of movable ring blocks 203 move toward each other, the two relative movable ring blocks 203 will respectively drive the two first extension blocks 204 to move toward the fixed ring block 202. The fixed ring block 202 is fixedly connected to the surface of the mounting roller 201 through multiple inner connecting columns 209. The inner diameter of the first extension block 204 is equal to the outer diameter of the second extension block 205. When the two movable ring blocks 203 move toward each other, the two connected first extension blocks 204 will slide and close along the outer surfaces of the two second extension blocks 205, and form a contact surface of the steel strip with the fixed ring block 202. After the longitudinally cut steel strip is placed between the adjusted multiple sets of movable ring blocks 203 by personnel traction, the electric telescopic rod 5 set on the top of the fixed frame 1 is started, and its telescopic end extends downward, driving the connecting frame 4 to move downward through the connecting rod 8 until the surface of the pressure roller 3 contacts the surfaces of multiple longitudinally cut steel strips, or the surfaces of multiple movable ring blocks 203, so that the longitudinally cut steel strip is pulled by the winding device, and the installation roller 201 and the pressure roller 3 will roll under the traction force of the longitudinally cut steel strip.

[0027] The effect achieved by the entire embodiment 2 is that, when in use, by fixing the fixed rod 207 between the two mounting blocks 210, the multiple sets of movable ring blocks 203 will slide along the surface of the fixed rod 207 when adjusting the spacing, thereby playing a limiting role. When the connecting frame 4 drives the pressure roller 3 to move downward, it will slide in the two hollow tubes 6 through the guide rod 7 symmetrically arranged on its top, thereby playing a limiting role, preventing the position of the connecting frame 4 from shifting when moving downward, affecting the limiting of the pressure roller 3 on the top of the longitudinally cut steel strip, and has high practicality.

[0028] Working principle: When the steel strip limit assembly of the longitudinal shearing machine is adjusted, the motor 208 is started, and rectangular grooves are symmetrically opened on the outer surface of the mounting block 210 on which the motor 208 is mounted. Battery packs are arranged in the two rectangular grooves to power the motor 208. When the output end of the motor 208 is working, it will drive the bidirectional threaded rod 206 to rotate forward and reversely in another mounting block 210. The multiple movable ring blocks 203 are set as multiple groups, and two movable ring blocks 203 are a group. Under the rotation of the bidirectional threaded rod 206, they will move in opposite directions or in opposite directions along the outer surface of the fixed rod 207. When the multiple groups of movable ring blocks 203 move toward each other, the two relatively movable ring blocks 203 will respectively drive the two first extension blocks 204 to move toward the fixed ring block 202. The fixed ring block 202 is fixedly connected to the surface of the installation roller 201 through multiple connecting columns 209 on the inside. The inner diameter of the first extension block 204 is equal to the outer diameter of the second extension block 205, so that when the two movable ring blocks 203 move toward each other, the two connected first extension blocks 204 will slide and close along the outer surfaces of the two second extension blocks 205, and close to the fixed ring block 202. The contact surface of the steel strip is formed. After the longitudinally cut steel strip is placed between the adjusted multiple sets of movable ring blocks 203 by personnel traction, the electric telescopic rod 5 set on the top of the fixed frame 1 is started, and its telescopic end extends downward, and the connecting frame 4 is driven to move downward through the connecting rod 8 until the surface of the pressure roller 3 contacts the surface of multiple longitudinally cut steel strips or the surface of multiple movable ring blocks 203, so that the longitudinally cut steel strip is pulled by the winding device, and the installation roller 201 and the pressure roller 3 will roll under the traction of the longitudinally cut steel strip, and the multiple sets of movable ring blocks 203 are rotated in the forward and reverse directions through the output end of the motor 208. The distance between the groups of movable ring blocks 203 can be adjusted to adapt to steel strips of different widths after longitudinal cutting. By fixing a fixed rod 207 between the two mounting blocks 210, the multiple groups of movable ring blocks 203 can slide along the surface of the fixed rod 207 when adjusting the spacing, thereby playing a limiting role. When the connecting frame 4 drives the pressure roller 3 to move downward, it will slide in the two hollow tubes 6 through the guide rod 7 symmetrically arranged on its top, thereby playing a limiting role, preventing the position of the connecting frame 4 from shifting when it moves downward, affecting the limiting of the pressure roller 3 on the top of the longitudinally cut steel strip, and has high practicality.
