The adjacent surfaces of the two second T-shaped blocks 414 are fixedly connected to the opposing surfaces of the two C-shaped clamps 416 respectively. The bottom surface of the testing table 1 is fixedly connected to... The device is equipped with a first connecting frame 411 and a second connecting frame 4113. A motor 412 is fixedly connected to the right side of the first connecting frame 411. The left end of the output rod of the motor 412 is fixedly connected through the right side of the first connecting frame 411 and extends to the inside of the first connecting frame 411. A double-threaded rod 413 is fixedly connected to the left end of the output rod of the motor 412. The left end of the double-threaded rod 413 is threaded through the right side of two second T-blocks 414 and extends to the left side of the two second T-blocks 414. The left end of the double-threaded rod 413 is rotatably connected to the inner side of the first connecting frame 411 through a bearing seat. Through the fixing component 41, the device adopts the design of a C-shaped clamp 416 and a threaded rod 417, which enables the device to clamp and fix steel of different thicknesses. At the same time, the double-threaded rod 413 drives the two second T-blocks 414 to move, thereby clamping and fixing steel of different lengths, enhancing the flexibility and adaptability of the device.

[0036] The second connecting frame 4113 is provided with a second sliding rod 415 on its inner side.

The insertion rod 4112 is inserted into the corresponding slot to lock the rotating plate 4111 and the threaded rod 417.

[0040] Before inspecting the steel, the locking frame 409 is removed from the locking slot, and the first T-block 407 is pushed downwards. The first T-block 407 slides on the first slide rod 408, causing the second protective frame 402 to move downwards, so that the second protective frame 402 slides into the empty slot. The locking frame 409 is then reinserted into the corresponding locking slot to lock the first T-block 407. The electric push rod 403 is activated, and the output rod of the electric push rod 403 extends, causing the pressure sensor 404 and the extrusion block 405 to move downwards.
