When the anti-collision plate is subjected to impact movement, the anti-collision plate, the movable rod, and the vertical plate form a right-angled triangle, and the right-angled side of the right-angled triangle becomes shorter. Therefore, the sleeve rod contracts into the anti-collision plate, so that the hypotenuse of the triangle also becomes shorter, pushing the movable rod to move into the sleeve.

The rubber strip increases the damping between the movable rod and the sleeve to reduce the impact force.

[0025] When the anti-collision plate 6 is impacted, a part of the impact force is transmitted to the mounting seat 1 through the vertical plate 4 and the support plate 5. At the same time, the anti-collision plate 6 moves. Since the anti-collision plate 6, the movable rod 9 and the vertical plate 4 form a right-angled triangle, the right-angled side of the right-angled triangle becomes shorter, so the sleeve rod 15 contracts into the anti-collision plate 6, making the hypotenuse of the triangle also shorter.

[0027] In the utility model, during use, when the anti-collision plate 6 is impacted, a part of the impact force is transmitted to the mounting seat 1 through the vertical plate 4 and the support plate 5, and the anti-collision plate 6 moves at the same time. Since the anti-collision plate 6, the movable rod 9, and the vertical plate 4 form a right-angled triangle, the right-angled side of the right-angled triangle becomes shorter, so the sleeve rod 15 contracts into the anti-collision plate 6, so that the hypotenuse of the triangle also becomes shorter, and the movement of the anti-collision plate 6 pushes the movable rod 9 to move into the sleeve 8. The spring 12 absorbs the impact force through elastic deformation, and pushes the anti-collision plate 6 to reset after being impacted. The rubber strip 10 increases the damping between the movable rod 9 and the sleeve 8, and reduces the impact force. Furthermore, a part of the impact force drives the mounting sleeve 18 to move longitudinally through the support arm 20, which further causes the spring 2 19 to undergo elastic deformation, thereby absorbing and buffering the impact force and protecting the robot from excessive impact.
