A second groove 5 is formed inside the mother - buckle 2 and above the first groove 4, a pull rod 501 is movably arranged inside the second groove 5, a spring 502 is sleeved outside the pull rod 501, one end of the pull rod 501 penetrates through one side of the mother - buckle 2 and extends outside the mother - buckle 2, a pulling ring 503 is fixedly arranged at one end of the pull rod 501, a clamping block 504 is fixedly arranged at the other end of the pull rod 501, and the clamping block 504 is movably connected with the insert block 3.

[0021] Specifically, a first connecting ring 101 is fixedly provided at a top of the sub - buckle 1, and a second connecting ring 201 is fixedly provided at a bottom of the mother - buckle 2.

[0022] In this implementation scheme, by setting the first connecting ring 101 and the second connecting ring 201, the user connects the sub - buckle 1 and the mother - buckle 2 to different ropes through the first connecting ring 101 and the second connecting ring 201 respectively, and then connects the other end of the rope to an object, so that the two objects can be connected, which has strong practicability and is convenient for the user to use.

[0023] Specifically, one end of the bidirectional threaded rod 401 penetrates through one side of the mother - buckle 2 and extends to the outside of the mother - buckle 2, and a rotating handle 402 is fixedly arranged at one end of the bidirectional threaded rod 401.

[0024] In this implementation scheme, by setting the rotating handle 402, the user only needs to rotate the rotating handle 402 to drive the bidirectional threaded rod 401 to rotate. The steps are simple and the operation is convenient, which has strong convenience and is convenient for the user to use.

[0025] Specifically, the connection relationship between the bidirectional threaded rod 401 and the nut seat 403 is a threaded connection, and a threaded hole adapted to the bidirectional threaded rod 401 is opened inside the nut seat 403.

[0026] In this implementation scheme, by setting the bidirectional threaded rod 401 and the nut seat 403, using the threaded connection relationship between the bidirectional threaded rod 401 and the nut seat 403, by driving the bidirectional threaded rod 401 to rotate, the nut seat 403 moves horizontally in the opposite direction along the outside of the bidirectional threaded rod 401.

[0029] Specifically, clamping grooves adapted to the clamping blocks 504 are formed on both sides of the insertion block 3, and the clamping blocks 504 are clamped in the clamping grooves of the insertion block 3.

[0030] In this embodiment, by providing the insertion block 3 and the clamping blocks 504, using the clamping relationship between the clamping blocks 504 and the insertion block 3, and through the extensibility of the spring 502, the clamping blocks 504 can be clamped into the clamping grooves on both sides of the insertion block 3, thereby enabling the connection between the male buckle 1 and the female buckle 2. When it is necessary to release the connection state between the male buckle 1 and the female buckle 2, by pulling the pull ring 503 outwards, the spring 502 is compressed, and then the pull rod 501 drives the clamping block 504 to move into the interior of the second groove 5, so that the clamping state between the clamping block 504 and the clamping grooves on both sides of the insertion block 3 can be released, and the disassembly of the male buckle 1 and the female buckle 2 can be realized, which has strong practicability and is convenient for users to use.

[0031] During use, the user first connects the male buckle 1 and the female buckle 2 to different ropes through the first connection ring 101 and the second connection ring 201 respectively, and then connects the other ends of the ropes to objects, so that the two objects can be connected. After that, the insertion block 3 and the connection block 301 of the male buckle 1 are inserted into the slot of the female buckle 2. By rotating the rotating handle 402 to drive the bidirectional threaded rod 401 to rotate, the nut seat 403 moves horizontally in the opposite direction along the outside of the bidirectional threaded rod 401, and then the nut seat 403 drives the clamping plate 404 to move horizontally in the opposite direction, so that the clamping plate 404 is clamped in the clamping grooves formed on both sides of the connection block 301, and the connection block 301 can be locked, realizing the connection between the male buckle 1 and the female buckle 2. Through the extensibility of the spring 502, the clamping blocks 504 can be clamped into the clamping grooves on both sides of the insertion block 3, thereby strengthening the connection between the male buckle 1 and the female buckle 2. When it is necessary to release the connection, first rotate the rotating handle 402 in the reverse direction to drive the bidirectional threaded rod 401 to rotate, so that the nut seat 403 drives the clamping plate 404 to move horizontally in the opposite direction, and the clamping state between the clamping plate 404 and the connection block 301 can be released. Then, by pulling the pull ring 503 outwards, the spring 502 is compressed, and then the pull rod 501 drives the clamping block 504 to move into the interior of the second groove 5, so that the clamping state between the clamping block 504 and the clamping grooves on both sides of the insertion block 3 can be released, and the disassembly of the male buckle 1 and the female buckle 2 can be realized.
