The two light barriers 642 are evenly distributed along the circumference of the suspension pin 64. The light blocking plate 642 is provided with a light transmitting hole 643. The opposed-type photoelectric switch 42 includes a switch body 421 and a mirror 422. The switch body 421 and the reflecting mirror 422 are fixed on both sides of the hanging notch 11, respectively. When the straightness of the hanging pin 64 is within the set range, the switch body 421, the reflector 422, and the light transmission hole 643 can be adjusted to be positioned on a straight line, that is, when the switch body 421, the reflector 422, and the light transmission hole 643 are adjusted to be positioned on a straight line, light emitted from the switch body 421 can pass through the light transmission hole 643 to be emitted to the reflector 422. The motor control unit 43 is electrically connected to the correlation photoelectric switch 42 and the suspension pin driving motor 41. In the initial state, one of the light blocking plates 642 is located between the switch body 421 and the reflector 422, and at this time, light emitted from the switch body 421 passes through the light transmission hole 7543 and is directed toward the reflector 422.

In use, when the suspension pin 64 is bent to a degree that the linearity exceeds the set range, the light blocking plate 642 blocks the light emitted from the switch body 421, the light is detected by the correlation type photoelectric switch 42 and fed back to the motor control unit 43, and the motor control unit 43 enables the suspension pin driving motor 41 to rotate 180 °. Subsequent stress forces the hanging pin 64 to be straighter, when the straightness meets the requirement, the light blocking plate 642 loses the shielding effect on light emitted by the correlation type photoelectric switch 42 (namely, the emitted relation can pass through the light hole), the hanging pin is bent by continuous stress, when the straightness does not meet the requirement, the light emitted by the correlation type photoelectric switch 42 is blocked by the light blocking plate 642 and detected by the correlation type photoelectric switch 42, and the motor control unit 43 drives the hanging pin to drive the motor 41 to rotate 180 degrees, so that circulation is carried out, and the hanging pin is prevented from being bent towards one direction all the time to influence the use.
