[0029] The electric push rod 24 drives the movable seat 23 to move in the groove cavity, and the movement of the movable seat 23 drives the measuring body 22 to move, so that the measuring body 22 can operate inside the pipe body 1.

[0030] Please refer to Figure 1 、 Figure 3 and Figure 5 , the clamping mechanism 3 is located on the outer wall of the tube body 1 and is used to clamp the tube body 1. The clamping mechanism 3 includes a threaded mechanism, a driving mechanism, a limiting mechanism and a supporting mechanism. The threaded mechanism is located at the top of the tube body 1, the driving mechanism is located in the middle of the threaded mechanism and is used to drive the threaded mechanism to work, the limiting mechanism is located at the bottom of the threaded mechanism and is used to limit the threaded mechanism, the supporting mechanism is located between the tube body 1 and the threaded mechanism and is used to support the threaded mechanism, the threaded mechanism includes a clamping plate 36 arranged on both sides of the tube body 1 and a movable plate 37 fixed to the top of the clamping plate 36, the outer wall of the movable plate 37 is screwed with a bidirectional screw 31, and the supporting mechanism includes a mounting sleeve installed on both sides of the bidirectional screw 31 and a mounting sleeve fixed to the bottom of the mounting sleeve. The fixing plate 310 has two support rods connected to the bottom of the fixing plate 310, and a contact plate 34 is installed at the bottom of the two support rods. The fixing plate 310 is connected to the working plate 5. The driving mechanism includes a protective shell 32 fixed to the top of the fixing plate 310 and a driving motor 33 fixed to the top of the protective shell 32. The output end of the driving motor 33 is connected to the transmission shaft, which extends to the interior of the protective shell 32 and is fixed with a first conical tooth 38. The outer wall of the bidirectional screw 31 is fixed with a second conical tooth 39, and the first conical tooth 38 is meshed with the second conical tooth 39.

[0031] The clamping plates 36 are placed on both sides of the tube body 1, and the contact between the contact plates 34 and the tube body 1 is used to effectively support the fixed plate 310. After the fixed plate 310 is supported, the drive shaft 33 is driven to rotate by the driving motor 33. The rotation of the drive shaft drives the first conical teeth 38 to rotate, and the rotation of the first conical teeth 38 drives the second conical teeth 39 to rotate. The rotation of the second conical teeth 39 drives the bidirectional screw 31 to rotate, and the rotation of the bidirectional screw 31 drives the movable plate 37 to move on its outer wall. The movement of the movable plate 37 drives the clamping plate 36 to move, and the movement of the clamping plate 36 gradually fits the tube body 1 until the tube body 1 is clamped. By clamping the tube body 1, the fixed plate 310 reinforces the working plate 5.

A limiting rod 43 is fixed on one side of the extrusion plate 41, and the limiting rod 43 is plugged into the clamping plate 36.

[0033] When the clamping plate 36 moves, it drives the extrusion plate 41 to move, so that the extrusion plate 41 first contacts the tube body 1, and the contact with the extrusion plate 41 causes it to move. The movement of the extrusion plate 41 drives the spring 42 to contract, and the contraction of the spring 42 causes the movable rod 44 to move. The movement of the movable rod 44 drives the blocking plate 45 to move. The movement of the blocking plate 45 allows the staff to observe the extrusion force of the extrusion plate 41, thereby controlling the clamping force of the clamping plate 36, thereby preventing excessive clamping from causing damage to the tube body 1.
