Working principle: First, the operator moves the self-locking sleeve 13 to the side of the elastic rotating rod 12, and the self-locking sleeve 13 squeezes the second compression spring 1301, so that the self-locking sleeve 13 sleeved on the safety hook 1 moves along the elastic rotating rod 12. Movement, when there is a distance between the top of the self-locking sleeve 13 and one end of the safety hook 1, the elastic rotating rod 12 can rotate around the rotating shaft at one end, so that the elastic rotating rod 12 and the safety hook 1 are separated. Locking means that the self-locking sleeve 13 is snapped back to the original position, and the self-locking sleeve 13 is pressed to the rotating end along the elastic rotating rod 12 again. The rotating rod 12 is pushed back to the original position to complete the clamping of the self-locking sleeve 13, so as to realize the convenient operation of the safety hook 1; It is connected with the safety lock 4 through the rotating shaft, and the rope clamping plate 8 is rotated to make it coincide with one end of the safety lock 4.

When the cross bar of the pin shaft 3 rotates to the horizontal position, so that pin shaft 3 crossbar one end passes through pin shaft hole 16, and pin shaft 3 is rotated to vertical again, and now pin shaft 3 is fixed on the top of tether block 2, and due to the elasticity of first compression spring 17, So that the pin shaft 3 itself will not move freely, and because the pin shaft 3 limits the position of the tether block 2, the downward twisting of the tether block 2 will not occur due to the operator's mistaken touch, thereby causing the self-locking block 6 Looseness occurs, thereby causing the safety lock 4 to fall. When the tether block 2 is stressed, because the tether block 2 and the self-locking block 6 rotate around the same axis, the locking end of the self-locking block 6 will tilt upwards. Due to the presence of the rope groove 9, the self-locking block 6 squeezes the safety rope 21 into the second rope groove 9, so that the self-locking block 6 engages the safety rope 21 more tightly, and increases the pressure on the safety rope 21. The friction force makes the safety pendant more secure.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model.
