At this time, the plug rod will move toward the shell plate, and the movement of the plug rod will drive the movement of the slide plate, and the movement of the slide plate will squeeze the spring, and then the connecting rod will continue to move, and when the plug hole on the outside of the connecting rod moves to a position corresponding to the position of the plug rod, the plug rod will be inserted into the plug hole, and the installation between the screw and the bolt head is completed.

[0008] As a preferred embodiment of the above technical solution, the number of springs, slides and plugs is the same as the shell plates, one end of the six springs are respectively fixedly connected to the inner sides of the six shell plates, and the other ends of the six springs are respectively fixedly connected to the six slides, one end of the six plugs is respectively fixedly connected to the side of the six slides away from the springs, and the other ends of the six plugs pass through the shell plates and the bolt heads are distributed on the inner sides of the sockets, and the outer ends of the six plugs are arranged in a trapezoidal shape.

[0009] The bolt is then released from the slot and the screw is engaged to the bolt, and the bolt is engaged with the screw by the user, so that the bolt head and the screw can be separated.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a bolt head, a screw rod, a nut, a fixing mechanism and a disassembly mechanism, so that when in use, the user can insert the connecting rod at the top of the screw rod into the insertion hole in the bolt head, and the connecting rod moves to a certain position in the insertion hole and contacts with the six insertion rods inside the insertion hole, and drives the insertion rod to move, at which time the insertion rod will move toward the shell plate, and the movement of the insertion rod will drive the slide plate to move, and the movement of the slide plate will squeeze the spring, and then the connecting rod will continue to move, and when the insertion hole outside the connecting rod moves to a position corresponding to the position of the insertion rod, the insertion rod will be inserted into the insertion hole, and the installation between the screw and the bolt head is completed, and then the user can install the equipment through the bolt head, the screw and the nut. When it is necessary to separate the bolt head from the screw, the user can turn the handle on the top of the threaded rod. The rotation of the handle drives the threaded rod to move. Since the threaded rod is threadedly connected to the threaded hole on the connecting rod, the threaded rod will move with the cooperation of the threaded hole. The movement of the threaded rod drives the convex plate to move. When the convex plate moves to a certain position, it will contact the plug rod in the connecting rod and drive the plug rod to move toward the shell plate. Similarly, the plug rod will gradually separate from the plug hole. When the plug rod is completely separated from the plug hole, the user can directly pull the screw out of the plug hole on the bolt head, thereby achieving the effect of disassembling and assembling the bolt head and the screw, thereby facilitating the user to replace different screws and bolt heads, thereby reducing the cost of replacement.

The number of springs 12, slide plates 13, and plug rods 14 is the same as that of the shell plate 11. One end of the six springs 12 is respectively fixedly connected to the inner side of the six shell plates 11, and the other ends of the six springs 12 are respectively fixedly connected to the six slide plates 13. One end of the six plug rods 14 is respectively fixedly connected to the side of the six slide plates 13 away from the spring 12, and the other ends of the six plug rods 14 pass through the shell plate 11 and the bolt head 1 and are distributed on the inner side of the insertion hole 15. The outer ends of the six plug rods 14 are arranged in a trapezoidal shape.

[0020] Through the above technical scheme, when in use, the user can insert the connecting rod 21 at the top of the screw rod 2 into the socket 15 in the bolt head 1. When the connecting rod 21 moves to a certain position in the socket 15, it will contact the six plugging rods 14 on the inner side of the socket 15 and drive the plugging rods 14 to move. At this time, the plugging rods 14 will move toward the shell plate 11. The movement of the plugging rods 14 will drive the slide plate 13 to move. The movement of the slide plate 13 will squeeze the spring 12. Then the connecting rod 21 continues to move.

The nut 3 is threadedly connected to the outer side of the screw rod 2, and the size of the nut 3 is the same as that of the bolt head 1. The disassembly mechanism comprises a connecting rod 21 inserted into the inner side of the insertion hole 15, and six insertion holes 22 penetrating the connecting rod 21 are arranged on the outer side of the connecting rod 21, and a threaded hole 23 is arranged on the top of the connecting rod 21. The threaded hole 23 A threaded rod 24 is connected to the inner thread, a convex plate 25 is fixedly connected to one end of the threaded rod 24, and a handle 26 is fixedly connected to the other end of the threaded rod 24. The size of the connecting rod 21 matches the socket 15. The convex plate 25 is distributed on the inner side of the connecting rod 21.

The positions of the six plug holes 22 correspond to the six plug rods 14. The connecting rod 21 is fixedly connected to the screw rod 2, and the size of the convex plate 25 matches the plug rod 14.

[0023] Through the above technical scheme, when in use, the user can rotate the handle 26 on the top of the threaded rod 24, and the rotation of the handle 26 drives the threaded rod 24 to move. Since the threaded rod 24 is threadedly connected to the threaded hole 23 on the connecting rod 21, the threaded rod 24 will move with the cooperation of the threaded hole 23, and the movement of the threaded rod 24 drives the convex plate 25 to move. When the convex plate 25 moves to a certain position, it will contact the insertion rod 14 in the connecting rod 21 and drive the insertion rod 14 to move toward the shell plate 11. Similarly, the insertion rod 14 will gradually separate from the insertion hole 22. When the insertion rod 14 is completely separated from the insertion hole 22, the user can directly pull the screw 2 out of the insertion hole 15 on the bolt head 1, thereby achieving the effect of facilitating the user to disassemble the bolt head 1 and the screw 2, and then facilitating the user to replace different bolt heads 1 and screws 2.

[0024] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
