[0025] In a specific embodiment, the anti-pull mechanism further includes a bearing seat 240, and a clamping member is provided on the bearing seat 240, and the clamping member clamps the material tube to limit the position.

[0026] Furthermore, the clamping member is a U-shaped clamping member 230 , and a handle screw is provided on the U-shaped clamping member 230 to clamp the material tube in the U-shaped clamping member 230 .

[0027] In this embodiment, two U-shaped clamping members 230 are provided, and a first handle screw 231 and a second handle screw 232 are respectively provided on the two U-shaped clamping members 230 to limit the material tube in the U-shaped clamping member 230 .

[0040] The upper part of the double-hole connector includes a through square hole, and the force-bearing end of the force sensor 250 is inserted into the square hole and then tightened and fixed using bolts.

[0041] The other end of the force sensor 250 is fixed to one end of the rotating shaft 242 by two bolts. The other end of the rotating shaft 242 sequentially passes through the first bearing 241, the bearing seat 240, and the second bearing 243.
