Abstract
The invention provides a fastening mechanism. The fastening mechanism comprises a screw. The screw is provided with a screw head or a nut connected with the screw, the screw head protrudes out of the screw in the radial direction, the nut or the screw head is provided with a spring shim, the bottom surface of the nut or the screw head is provided with tooth grooves, and the spring shim is provided with elastic teeth. The elastic teeth are meshed with the tooth grooves in the bottom surface of the nut or the screw head in an inverted-tooth mode, and thus the nut or the screw head is only allowed to rotate in the screwing-down direction; the elastic teeth are partially exposed out of the periphery of the nut or the screw head, then the elastic teeth can deform as the exposed parts of the elastic teeth are pressed, and thus inverted-tooth meshing between the elastic teeth and the nut or the screw head is relieved. The spring shim is provided with an anti-rotating structure. The fastening mechanism has wide application occasions, makes fastening operation easy and has a self-locking function; the connecting strength of the fastening mechanism is as high as that of welding, and the fastening mechanism can also be disassembled as needed; furthermore, the fastening mechanism is simple in structure and low in cost.

Embodiment
As Figure 1-4.Retention mechanism provided by the present invention, comprises screw rod 1, and described screw rod 1 is provided with screw head 10, and screw head 10 radial convex is for screw rod 1.
Screw head 10 is configured with compression spring 2, the bottom surface of screw head 10 is arranged teeth groove 11, compression spring 2 is enclosed within outside screw rod 1, compression spring 2 is arranged Elastic Teeth 21, and the teeth groove 11 on described Elastic Teeth 21 and screw head bottom surface is pawl engagement, only allow a screw rod to rotate towards tightening direction, and Elastic Teeth 21 also have part to expose in the periphery of screw head 10, Elastic Teeth 21 can be out of shape because of its exposed portion pressurized, remove and engage with the pawl of screw head.The inner hole wall of described compression spring has the rotation prevention structure 22 of bending downwards.Rotation prevention structure 22 can with screw rod 1 the hole wall in hole worn coordinate compression spring can not be rotated, thus form the removable anti-rotation loosening configuration of self-locking.The rotation prevention structure 22 of compression spring also can be the structure on the peripheral position of compression spring or end face, bottom surface.
Described compression spring can adopt stamping part, forms its profile, Elastic Teeth and described rotation prevention structure in punching press.
The bottom 12 outwards annular protrusion of bolt head, teeth groove 11 on screw head bottom surface forms link spring shape at screw head outer side bottom surface, in order to guarantee compression spring is arranged, Elastic Teeth crooked position is not compacted and elastic force is lasting, described screw arrangement has male member 3, male member 3 pads the below at screw head 10, male member 3 exceeds the groove face of teeth groove 11, so when installing connection, ensure that the bending root of Elastic Teeth 21 is not compacted, make the Elastic Teeth 21 of compression spring 2 reliably can either carry out pawl with the teeth groove 11 of screw head 10 to engage, screw rod 1 tightening direction can not be obstructed when rotating, otherwise then can not rotate, and when disassembly is desired, telescopic instrument (electronic or manual) is enclosed within screw head 10 extroversion press down, Elastic Teeth 21 can evenly be flattened and all solutions removes pawl engagement, can carry out unscrewing operation.The inner side of compression spring 2 is plane round 23, and outside is described Elastic Teeth 21, and male member 3 can pad on plane round 23.
