On the basis of the above technical solution, according to the difference of the concrete structure and the connection relationship between the spiral rotating component 61 and the horizontal pulling component 62, the utility model discloses can extend the concrete implementation scheme of multiple difference, supply people to implement and select. The various schemes extended are specifically as follows:

one is, as shown in fig. 2 to 4, the spiral rotating component 61 is a cylinder, a reducing ring groove 611 is further provided on the lower surface of the cylinder from large to small, a sleeve upper portion 612 is further provided on the upper portion of the cylinder, and the positioning component 63 is a single-ring outward ring tooth integrally provided or formed on the sleeve upper portion 612.

As shown in fig. 4, a tool operation hole 613 is further provided on the top end of the socket upper portion 612 so as to rotate the screw rotation member 61 by a tool operation.

In order to keep the unidirectional outer ring teeth and the unidirectional inner ring teeth 111 meshed with each other all the time and not to automatically release, as shown in fig. 2 to 4, a return spring 7 is further provided at the bottom end of the spiral rotating member 61, one end of the return spring 7 abuts against the bottom end of the spiral rotating member 61, and one end of the return spring 7 abuts against the inner cavity wall of the insert 1. The spiral rotating part 61 is forced to move upwards all the time by the reset elasticity of the reset spring 7, so that the unidirectional outer ring teeth and the unidirectional inner ring teeth 111 are always meshed with each other. When the locking state of the lock pin 3 and the locking block 4 needs to be changed into unlocking, the lower spiral rotating component 61 is vertically pressed, and the spiral rotating component 61 is rotated in the opposite direction, so that the single-direction outer ring gear and the single-direction inner ring gear 111 are disengaged, the movable lever component 52 is driven to slide towards the front end direction of the embedded body 1, the upper protruding part 54 and the lower protruding part 55 are in a mutually staggered state from a laminated state, and the state of the lock pin 3 and the locking block 4 is changed from the state shown in fig. 3 back to the state shown in fig. 2, namely, unlocking is completed.

The embedded body 1 is correspondingly provided with a sleeving hole 11, the sleeving upper part 612 is sleeved with the sleeving hole 11, as shown in fig. 8, the embedded body 1 is further provided with a sleeving shaft hole 12, and the sleeving lower part 614 is sleeved with the sleeving shaft hole 12, that is, as shown in fig. 6.

The horizontal pulling component 62 is a bracket body, an eccentric shaft hole 622 is further formed in the bracket body, and the eccentric wheel component is sleeved in the eccentric shaft hole 622; the positioning part 63 is a tilting tail integrally processed on the rear end of the bracket body, and the rear end of the embedded body 1 is also provided with a positioning hole 13 for the tilting tail to be sleeved.

The difference between this solution and the first and second solutions is that when the conical cylinder is rotated downward, the conical cylinder forces the nesting hole 623, the horizontal pulling member 62 is pushed and pulled to move from the front end of the embedded body 1 to the rear end of the embedded body 1, and then the movable lever member 52 moves, so as to achieve the purpose of locking, and the state can be changed from fig. 10 to fig. 11, which can be intuitively obtained. And the external thread is used as the positioning component 63 to prevent the back loosening phenomenon, thereby realizing the locking effect. The operation and principle are similar to the first and second schemes, and will not be described repeatedly.

On the basis of the scheme, in order to further reduce the structure complexity of the utility model discloses a reduce the volume of whole mechanism, make it more compact, the utility model discloses also can be with installation fixed establishment 2 and spiral rotary part 61 integration together.
