Furthermore, a movable gap is formed between the clamping block and the inner upper surface of the first fixed shell, and springs are arranged on the clamping block and the inner lower surface of the first fixed shell; the thickness of the clamping block is not less than that of the limiting piece; the thickness of the movable gap is not more than that of the limiting sheet. The reserved movable gap can facilitate the movement of the limiting piece and is matched with the spring at the lower side of the clamping block in a pressing way, so that the clamping and the releasing of the lock catch are realized; the thickness of the clamping block is not less than the thickness of the limiting piece, and the thickness of the movable gap is not more than the thickness of the limiting piece, so that the limiting piece is not easy to disengage from the clamping block, the connection strength is high, and the fastening performance is strong.

Furthermore, limiting nuts are arranged on the outer surfaces of the joints of the limiting pieces and the second fixing shell, the rotating positions of the limiting pieces are judged through the limiting nuts on the surfaces, and the connecting positions of the limiting pieces and the clamping blocks are simply and clearly judged, so that the connecting strength of the limiting pieces and the clamping blocks is ensured during use.

Furthermore, the limiting nut is fixedly connected with the limiting sheet. When this hasp uses, because of stop nut and spacing piece fixed connection, can realize breaking away from of spacing piece and joint piece through the direction of twisting stop nut soon, further improved the joint strength when stop nut and joint piece use, it is firm to use, and the fastening is strong.

The utility model has the advantages that: by adopting the scheme, the clamping type lock catch with the structure is simple in structure, the limiting piece is clamped with the clamping block, the connection is flexible, and the clamping type lock catch can be repeatedly used; the arranged leading-in angle and leading-out angle can facilitate the clamping and the disengagement of the limiting sheet and the clamping block, and the use is convenient; the reserved movable gap can facilitate the movement of the limiting piece and is matched with the spring at the lower side of the clamping block in a pressing way, so that the clamping and the releasing of the lock catch are realized; the thickness of the clamping block is not less than that of the limiting piece, and the thickness of the movable gap is not more than that of the limiting piece, so that the limiting piece is not easy to separate from the clamping block, the connection strength is high, and the fastening performance is strong; the rotating position of the limiting sheet is judged through the limiting nut on the surface, and the connecting position of the limiting sheet and the clamping block is simply and clearly judged, so that the connecting strength of the limiting sheet and the clamping block in use is ensured; when this hasp uses, because of stop nut and spacing piece fixed connection, can realize breaking away from of spacing piece and joint piece through the direction of twisting stop nut soon, further improved the joint strength when stop nut and joint piece use, it is firm to use, and the fastening is strong.
