When the sliding plate slides upward, it drives the square block to slide downward through the tooth plate and gear; S2: Sliding clamping: When the square block slides downward, it will rotate through the V-shaped plate and drive the clamping block to rotate on the side wall of the limit plate through the telescopic middle plate.

When the sliding plate slides down, the cable will be tested for tension. A tension detector will transmit the test data to the background to complete the detection purpose.

[0014] The present invention has the following beneficial effects: 1. In the present invention, when the sliding plate slides down, the cable can be clamped by the lower clamp and the cable can be stretched when the sliding plate slides down. When it is necessary to perform tensile testing on other parts of the cable, the cylinder is started to drive the sliding plate to slide upward. When the sliding plate slides upward, it slides on the outer surface of the gear through the toothed plate and drives the gear to rotate when sliding. When the gear rotates, it drives the threaded rod to slide downward through the toothed plate. When the threaded rod slides downward, the insertion rod in the fixed cylinder slides in the threaded groove on the outer surface of the threaded rod under the guidance of the spring plate. At this time, when the threaded rod slides downward, the threaded groove on the outer surface of the threaded rod will be blocked by the insertion rod, so that the threaded rod It rotates while sliding down, and when the threaded rod slides downward, it will drive the square block to slide downward synchronously through the telescopic rod. When the square block slides downward, it will slide in the direction of the cable along the guidance of the inclined surface of the inclined frame. When the square block slides in the direction of the cable, it will cover the surface of the cable, and then when the square block slides downward, it will drive the cable to slide downward. Then, when testing is needed, you only need to start the sliding plate to move downward again to clamp the cable and perform tensile testing. By repeated use in this way, uninterrupted testing of the cable tensile test can be achieved. Compared with the traditional method of intercepting the cable for testing, it can save the operation time before testing and improve the testing rate.

[0015] 2. In the present invention, when the threaded rod slides downward, the threaded rod will be guided by the inserted rod in the fixed tube so that the threaded rod will slide downward in the fixed tube and rotate at the same time. When the threaded rod slides downward and rotates, the rotation of the threaded rod will drive the cam plate to rotate synchronously. When the downward movement of the threaded rod drives the square block to slide downward, the downward movement of the square block will slide downward between the two V-shaped plates through the telescopic push plate and make the two V-shaped plates rotate relative to each other. When the two V-shaped plates rotate relative to each other, the side wall of the V-shaped plate will push the inner wall of the rectangular knife and provide a certain support therein. Then, when the telescopic push plate continues to slide downward, the telescopic push plate will shrink. Then, when the rotation of the threaded rod drives the cam plate to rotate, the cam plate The rotation will push the side wall of the rectangular knife, and when the side wall of the rectangular knife is squeezed by the cam plate, it will squeeze and cut the cable. When the rectangular knife cuts the cable, the deformed part of the cable under the squeezing of the two clamping blocks will be separated from the cable under the cutting of the rectangular knife. Then, when the square block slides down and drives the cable to slide down synchronously, the new cable can pass through the two clamping blocks under the downward push of the square block to prepare for the next tensile test, reducing the situation where the lower clamp clamps the deformed part of the cable when clamping the cable, resulting in premature breakage of the cable during tensile testing. This can effectively reduce the interference of partial deformation on the cable on subsequent tensile testing during subsequent tensile testing, thereby improving the accuracy of subsequent testing.

[0016] 3. In the present invention, when the downward sliding of the telescopic push plate drives the two V-shaped plates to rotate in opposite directions, the opposite rotation of the two V-shaped plates will drive the piston rod to slide in the piston cylinder. When the piston rod slides inside the piston cylinder, the sliding of the piston rod will squeeze the gas between the piston rod and the piston cylinder. When the gas inside the piston cylinder is squeezed by the piston rod, it will enter the inside of the flexible layer in the clamping block through the connecting pipe. When the gas enters, the flexible layer on the clamping block will expand, so that the expanded flexible layer can tightly cover the cable, thereby improving the connection between the cable and the clamping block. The friction force can be increased, and then the cable can be pulled by the lower clamp, and the increased friction force can further drive the two clamping blocks to clamp the cable tightly. At the same time, when the clamping block clamps the cable tightly through the expanded flexible layer, the increased friction force can clamp the cable tightly, so that the clamping block can better clamp and fix the cable during the detection process, reducing the cable from sliding or shaking during detection due to the unstable clamping of the clamping block on the cable, thereby further improving the accuracy of the detection process and improving the detection efficiency.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the side wall of the rectangular knife 601 is squeezed by the cam plate 306, the cable will be squeezed and cut. When the rectangular knife 601 cuts the cable, the deformed part of the cable will be separated from the cable under the squeezing of the two clamping blocks 603. Then, when the square block 402 slides down and drives the cable to slide down synchronously, the new cable can be pushed downward by the square block 402 to pass between the two clamping blocks 603 to prepare for the next tensile test, reducing the situation where the lower clamp 105 clamps the deformed part of the cable when clamping the cable, resulting in premature breakage of the cable during the tensile test. It can effectively reduce the interference of partial deformation on the cable on subsequent tests during subsequent tensile tests, thereby improving the accuracy of subsequent tests.

[0035] When the telescopic push plate 501 slides downward and drives the two V-shaped plates 502 to rotate in opposite directions, the opposite rotations of the two V-shaped plates 502 drive the piston rod 504 to slide in the piston cylinder 505. When the piston rod 504 slides inside the piston cylinder 505, the sliding of the piston rod 504 squeezes the gas between the piston rod 504 and the piston cylinder 505. When the gas inside the piston cylinder 505 is squeezed by the piston rod 504, it enters into the flexible layer in the clamping block 603 through the connecting pipe. When the gas enters, the flexible layer on the clamping block 603 expands, so that the expanded flexible layer can tightly cover the cable, thereby providing a The friction between the high cable and the clamping block 603 can be increased, so that after the cable is pulled by the lower clamp 105, the increased friction can further drive the two clamping blocks 603 to clamp the cable tightly. At the same time, when the clamping block 603 clamps the cable tightly through the expanded flexible layer, the increased friction can enable the clamping block 603 to better clamp and fix the cable during the detection process, reducing the sliding or shaking of the cable during detection due to the unstable clamping of the clamping block 603 on the cable, thereby further improving the accuracy of the detection process and improving the detection efficiency.
