[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions 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. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 As shown, a quick-release buckle structure for a tower foot spike climbing fall arrester comprises a structural plate 1, a side cover 2 is arranged on one side of the structural plate 1, the structural plate 1 and the side plate are fixed in three phases by three screws, a cavity 3 is formed between the side cover 2 and the structural plate 1, a buckle plate 4 is rotatably arranged in the cavity 3, and the buckle plate 4 is in the shape of a "hook".

[0023] In this embodiment, in order to guide the rotation of the buckle plate 4, a limit block 11 is installed on the structural plate 1. The limit block 11 is arranged inside the structural plate 1. A pin rod 12 is installed on the outer side of the limit block 11. The outer end of the pin rod 12 is movably connected to the buckle plate 4, and the buckle plate 4 rotates around the pin rod 12.

[0024] In the utility model, a latch 10 is installed on the inner side of the side cover 2, and the latch 10 is arranged corresponding to the buckle plate 4. At the same time, an elastic member is installed on the latch 10, wherein the elastic member is a spring, and the other end of the spring is fixed to the buckle plate 4. When the trip is in a closed state, the spring is in its original state, and when the trip is in an open state, the spring is in a stretched state.

[0025] In this embodiment, a limiting cover 5 is provided on the top surface of the structural plate 1, and a threaded hole 1 is opened on the top surface of the structural plate 1. The number of the threaded holes 1 is two, and the two threaded holes 1 are symmetrically arranged. At the same time, two through holes 1 are opened on the top surface of the limiting cover 5, and the two through holes 1 correspond to the two threaded holes 1. Screws 14 threadedly connected to the two threaded holes 1 are inserted through the two through holes 1. The two screws 14 fix the limiting cover 5 to the structural plate 1, and a through hole 5 13 is opened on the top surface of the structural plate 1 in the vertical direction, and the through hole 5 13 is located between the two threaded holes 1.

[0026] In this embodiment, a plunger 6 is movably provided on the limit cover 5, and the bottom end of the plunger 6 is in contact with the buckle plate 4.
