Preferably, the reset piece includes reset rod and coupling spring, the circular slot has been seted up on the surface of coupling head portion, coupling spring installs the inside of circular slot, the one end of reset rod is installed the inside of circular slot.

Preferably, the number of the movable clamping blocks is four, and the movable clamping blocks are annularly arranged at the edge position of the connecting head.

Preferably, the outer edges of the four moving blocks are all provided with smooth cambered surfaces.

Preferably, a support rod is mounted on the surface of the connecting head, and one end of the support rod, which is far away from the connecting head, is mounted on the surface of the threaded portion.

Preferably, the position of the supporting rod is placed at a position between the moving blocks.

Preferably, the depth of the circular groove is greater than the length of the reset rod.

Preferably, the size of the combination of the movable clamping block and the connecting head is smaller than the inner diameter of the threaded part.

Preferably, the circular groove is matched with the shape of the reset rod.

Preferably, the height of the coupling head is the same as the height of the movable latch.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through setting up the removal fixture block and the piece that resets, when needs follow opposite direction and screw in, will remove the fixture block through the piece that resets and remove the position department that is close to the connecting head for the nut has the surface of sufficient space precession screw thread portion, just loosens the removal fixture block this moment, makes it get back to initial state, just can prevent that the nut from being unscrewed by accident, can enough guarantee the normal use effect of bolt, also can follow the contralateral installation nut simultaneously, improves the application scope of whole bolt.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a machine tooth bolt, includes screw thread portion 1 and connects head 2, connecting head 2 keeps away from horizontal groove 3 has been seted up to the one end of screw thread portion 1, screw thread portion 1 is close to connecting head 2's position department sets up movable fixture block 4, movable fixture block 4 is connected through the piece 5 that resets connecting head 2's inside.

In this embodiment, by providing the movable latching block 4 and the reset member 5, when the screw-in operation is required to be performed from the opposite direction, the movable latching block 4 is moved to the position close to the connecting head 2 by the reset member 5, so that the nut has enough space to screw into the surface of the threaded portion 1, and at this time, the movable latching block 4 is loosened to return to the initial state, so that the nut can be prevented from being accidentally screwed out.

Specifically, the reset piece 5 includes a reset rod 51 and a connecting spring 52, a circular groove 53 is formed on the surface of the connecting head 2, the connecting spring 52 is installed inside the circular groove 53, and one end of the reset rod 51 is installed inside the circular groove 53.

In this embodiment, when the restoring rod 51 moves, the restoring rod 51 can be shortened or lengthened as required due to the elastic action of the connecting spring 52.

Specifically, the number of the movable blocks 4 is four, and the movable blocks are annularly arranged at the edge of the connecting head 2.

In this embodiment, the four movable blocks 4 are arranged to improve the blocking capability of the whole structure, thereby increasing the possibility of preventing the falling of the movable blocks.

Specifically, the outer edges of the four movable blocks 4 are all set to be smooth cambered surfaces.
