The distance between the side of the shielding part 120 near the rotating shaft 400 of the trigger piece 200 and the rotating shaft 400 of the trigger piece 200 can be flexibly adjusted according to the actual use requirement.

In this way, the rotating shaft 400 of the trigger piece 200 at least partially passes through the second avoidance opening 140, so that the gap between the rotating shaft 400 of the trigger piece 200 and one side of the shielding part 120, which is close to the rotating shaft 400 of the trigger piece 200, extends along a curve, the length of the gap increases, and then the difficulty that a cable in a robot passes through the gap and moves into the moving track of the trigger piece 200 increases, thereby improving the shielding reliability of the shielding piece 100.

As shown in fig. 1 and 4, alternatively, at least two connection portions 110 are provided, where at least two connection portions 110 are correspondingly disposed on two sides of the shielding portion 120, when the shielding portion 120 shields the moving track of the trigger piece 200, a distance between a side of the shielding portion 120, which is close to the switch body 300, and the switch body 300 is smaller than a diameter of the cable, and a distance between a side of the shielding portion 120, which is close to the rotating shaft 400 of the trigger piece 200, and the rotating shaft 400 of the trigger piece 200 is smaller than a diameter of the cable, where when a projection of the shielding portion 120 on the mounting body 500 covers the moving track of the trigger piece 200, the switch body 300, the rotating shaft 400 of the trigger piece 200, and at least two connection portions 110 are disposed on different sides of the shielding portion 120, respectively. In this way, the shielding part 120, the switch body 300, the rotating shaft 400 of the trigger piece 200, and at least two connecting parts 110 can block cables in the robot, so that the cables in the robot can not move into the moving track of the trigger piece 200, and the shielding reliability of the shielding piece 100 is improved.
