The adjustment seat 2 is a split design with upper and lower parts, and a connector is rotatably connected thereon. The connector is provided with two groups, which are used to clamp the detection shaft and the drive shaft.

[0030] The cross section of the lower seat 201 of the adjustment seat 2 is T-shaped, and a threaded hole is provided on the auxiliary ear of the lower seat 201, which corresponds to the position of the adjustment hole 101 and matches the size. It can be fixed by bolts, and the placement position can also be adjusted. A positioning block is provided on the top surface of the lower seat 201, and a positioning groove is provided on the bottom surface of the upper seat 202. The positioning block and the positioning groove are adapted to each other, so as to realize bolt fixation, and a hole connected to the top is provided in the positioning groove, and a threaded hole is provided on the top surface of the positioning block. The bolt passes through the hole and cooperates with the threaded hole to realize the cooperation between the upper seat 202 and the lower seat 201 to complete the fixation. A through hole that communicates left and right is provided in the middle of the junction of the upper seat 202 and the lower seat 201 for placing the connector.

[0031] The connector body is composed of two groups of rotating shafts 3, which are divided into AB parts. One group of rotating shafts 3 is provided with protrusions at the facing ends, and the other group is provided with grooves. The two are plugged in, and then the rotating shafts 3 are limited and fixed by matching with the through holes and the annular grooves in the middle (the cross-section of the rotating shaft 3 is T-shaped).

[0032] A rotating groove 301 is provided on the opposite end face of the rotating shaft 3. There are three groups of rotating grooves 301 arranged in a circular array. A rotating rod 302 is rotatably connected in the rotating groove 301. A torsion spring is provided at the connection of the rotating rod 302. One end of the rotating portion 401 of the clamping arm 4 is coaxially arranged with the rotating rod 302. Under the setting of the torsion spring, the clamping arm 4 is in an open state. The threaded section on the outer wall of the rotating shaft 3 is meshed with the threaded section on the inner wall of the rotating member 6. The rotating member 6 moves outward and presses against the arc surface of the clamping arm 4, thereby moving the clamping arm 4 toward the central axis.
