[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example

[0022] like Figures 1-2 As shown, a climbing anti-fall safety auxiliary tool comprises a safety belt and two groups of hook components. The safety belt is a safety belt commonly used in existing double-rope double-hook safety belts. A D-shaped ring is also provided on the back of the safety belt. Both groups of hook components are connected to the D-shaped ring through a safety rope. The hook component comprises a hook body and a locking member hinged to the hook body. The locking member comprises a locking portion 3 and a driving portion 4 which are axially angled with each other. The hook body comprises a handle 2 and a hook portion 1. The locking portion 3 is located below the hook portion 1, and the driving portion 4 is located on the side of the handle 2 away from the hook portion 1. During operation, the staff member holds the driving portion 4 and the handle 2 by hand at the same time. When the foot spike needs to be inserted, the driving portion 4 and the handle 2 are pinched to increase the gap between the locking portion 3 and the hook portion 1. After the foot spike is inserted, the driving portion 4 is released, and the locking portion 3 rebounds, thereby being fixed on the foot spike.

[0023] The locking portion 3 and the driving portion 4 are integrally formed, and the hook portion 1 and the handle 2 are integrally formed, which is more firm and can reduce weight.

[0024] The connection between the locking portion 3 and the driving portion 4 is hinged to the hook body.

[0025] The hook body is provided with an opening facing the hook portion 1 , the locking member passes through the opening and is connected to the hook body via a hinge in the opening; a reset component is provided at the connection between the hook body and the locking member.

[0026] The reset component may include any spring capable of achieving a reset function, such as a cylindrical compression spring. In this embodiment, a torque spring sleeved on the hinge is used, one end of the torque spring is fixed to the hook body, and the other end is fixed to the locking portion 3. Considering that this tool is an outdoor work tool, the reset component and the metal parts of the overall structure should have a rust-proof function.

[0027] The locking portion 3 is provided with a plurality of slots on one side close to the hook portion 1. The slots are arc-shaped and are used to clamp the foot spikes, and include adjacent first slots 301 and second slots 302, wherein the second slots 302 are close to the distal end of the locking portion 3; the radius of the second slots 302 is greater than the radius of the first slots 301. By providing a plurality of slots, the adaptability of the locking portion 3 can be improved, and currently it can adapt to foot spikes with wire diameters of 16mm, 20mm, and 24mm, and has a wider range of applications.

[0028] A hanging ring 201 is provided at one end of the handle 2 away from the hook portion 1 , and a safety rope is connected via the hanging ring 201 .

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
