Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, and as shown in fig. 1-4, a single-way high-efficiency screwing hexagon bolt comprises a screw body 1, wherein an auxiliary screwing mechanism is arranged at the upper end of the screw body 1, and a nut screwing mechanism is arranged at the lower end of the screw body 1;

the auxiliary twisting mechanism comprises a screw cap 2 on the upper surface of a screw rod main body 1, a round groove 3 is formed in the center of the upper surface of the screw cap 2, a clamping groove I4 is formed in the side surface of the upper end of the round groove 3, a clamping spring I5 is installed in the clamping groove I4, a rotating block 6 is installed on the inner surface of the round groove 3, a hexagonal groove 7 is formed in the upper surface of the rotating block 6, a triangular block I8 is installed on the lower surface of the rotating block 6, and a triangular block II 9 corresponding to the triangular block I8 is installed at the lower end of the;

the nut screwing mechanism comprises a nut 10 on the side surface of the lower end of the screw rod main body 1, internal threads 11 are installed on the inner ring of the nut 10, a second clamping groove 12 is formed in the side surface of the lower end of the nut 10, a second clamping spring 13 is installed in the second clamping groove 12, a rotating ring 14 is installed at the lower end of the nut 10, a third triangular block 15 is installed at the upper end of the rotating ring 14, a fourth triangular block 16 is installed on the lower surface of the nut 10, and a pressure spring 17 is installed between the second clamping spring.

The lower end of the screw body 1 is provided with an external thread 18.

The side surface of the lower end of the screw cap 2 is provided with a fixing ring 19, and a larger friction force can be generated between the screw cap and a workpiece under the premise of saving cost and raising cost through the action of the fixing ring 19.

In the embodiment, the use method of the bolt is similar to that of the traditional bolt, firstly, the screw body 1 penetrates through an object to be fastened, then the nut screwing mechanism part is sleeved at the lower end of the screw body 1, the nut 10 can be screwed manually under the condition of not applying force in the early stage, the traditional bolt fastening method is to screw the nut 10 part, the screw body 1 is not moved, and the nut 2 and the screw body 1 can be screwed according to the actual working condition; when the nut 10 part needs to be screwed, the force application end of the common wrench is tightly clamped on the rotating ring 14 and rotates towards the corresponding direction, the triangular block III 15 on the rotating ring 14 can drive the triangular block IV 16 to synchronously rotate when rotating, so that the screwing effect is achieved, the common wrench resets by rotating a certain angle, the common wrench moves relatively by utilizing the characteristics of the triangular block III 15 and the triangular block IV 16 when resetting, at the moment, the rotating ring 14 compresses the pressure spring 17, and the quick screwing effect can be achieved by repeating the operation;
