Furthermore, sliding connection has the baffle to the outside cover of round pin axle body is established, the surperficial one side fixedly connected with spring of baffle, the spring housing is established in the outside of round pin axle body, the one end of spring and the surperficial one side fixed connection of outer hexagonal turning round can change the distance that the round pin axle body was installed between the connecting piece, are convenient for adjust, improve the scope that this round pin axle used, and the practicality is stronger.
Furthermore, the outer surface of the outer hexagonal rotary head is provided with the inner hexagonal rotary head on one side, so that the inner hexagonal rotary head can be pushed and pressed conveniently, and the operation is very convenient.
Furthermore, the nut and the spiral groove are in threaded rotation connection, the structure is simple, and the nut and the spiral groove can be conveniently installed in a threaded rotation mode.
Furthermore, the diameter of the baffle is larger than that of the pin shaft body.
Furthermore, the pin shaft body is made of high-strength steel, so that the strength is higher, the service life of the pin shaft is prolonged, and the practicability is higher.
The utility model has the advantages that:
1. the utility model discloses a limited subassembly that sets up, when installing the great connecting piece of width and using, will sell the axle body and insert the inside of installing at the connecting piece, when installing longer connecting piece, the promotion baffle of exerting oneself makes the extrusion spring, through the internally mounted elasticity cylindric lock of cylindric lock hole, can install fixedly for more firm when connecting, can adjust when the connecting piece of different width sizes is installed, improve the application range of round pin axle, the practicality is stronger.
2. The utility model discloses a thread groove and the nut that set up, if the width of connecting piece is less than the distance between cylinder pinhole and the baffle, rotate through the nut screw thread on the helicla flute and be connected for the one end of nut is laminated with one side of connecting piece, so that realize installing the use to the less connecting piece of width, and it is more convenient in the in-process of operation, the practicality is stronger.
