The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention are fully and clearly described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them.

As shown in fig. 1 to 5, one embodiment of the invention provides that a pulley 1, a hook 6, a stopper 2 and a locking block 5 are respectively connected with two side plates 4 through a shaft I7 and a shaft II8, the stopper 2 is kept in single-phase locking of a circular chain through a spring I3, and the locking block 5 is kept in meshing locking with the hook 6 through a spring II 9. Pulley 1 is the circular middle chain ring draw-in groove 11 that is equipped with restriction chain ring 10 position to stopper 2 is equipped with opens spacing round hole 21 of using, and locking piece 5 is equipped with for the cuboid top surface opening and closing deep hole 51 side and is equipped with locking tooth I52, and lifting hook 6 one end is equipped with the locking tooth II61 with the locking tooth I52 meshing of locking piece 5, and the other end is equipped with the hook foot 62.

For example, the chain ring 10 is placed in the chain ring clamping groove 11 of the pulley 1, then the stopper 2 locks the chain ring 10 in a single phase under the action of the spring I3, the other end of a binding adjustment tensioner hangs the hoisting circular chain or the end ring of the binding circular chain or other accessories into the hook bottom 62 of the hook 6, the direction of the locking tooth II61 of the hook 6 is manually pressed down to enable the locking tooth II61 to be meshed with the locking tooth I52 of the locking block 5, the locking is realized under the action of the spring II9, then the circular chain above the pulley 1 is tightened to complete the length adjustment of the hoisting circular chain or the tensioning of the binding circular chain, a round steel is inserted into the deep hole 51 and is pressed towards the direction of the hook 6 to enable the binding adjustment tensioner to be in a tensioning state, and then the round hole 21 of the stopper 2 is lifted to adjust the position of the circular chain.
