Referring to fig. 8, since the pressing spring 233 may be tightened to be caught when the screw block 212 is screwed, a rotation ring groove 234 into which the inner side of the second stopper 232 is inserted is formed at the lower end of the screw block 212, so that the pressing spring 233 is less likely to rotate together when the screw block 212 rotates.
In embodiment 2 of the present application, an implementation principle of an automatic bending device for a preformed armor rod fitting is as follows: when the preformed armor rods with different diameters need to be machined, the screwing block 212 is pulled to enable the clamping convex points 221 to be separated from the groove 222, the compression spring 233 compresses and deforms at the moment, the screwing block 212 is rotated, the adjusting screw 211 rotates in the connecting portion 114 at the moment, the adjusting block 200 moves, accordingly, the gap between the rotating column 132 and the adjusting column 134 is adjusted, and the purpose of adjusting the size of the limiting ring groove 131 is achieved.
After the adjustment is finished, the screwing block 212 is loosened, the clamping convex points 221 are embedded into the grooves 222 through the compression springs 233, so that circumferential fixation is achieved, and the possibility of loosening of the screwing block 212 is reduced. In the embodiment, the groove 222 is sufficiently provided in the circumferential direction, so that the locking protrusions 221 can be almost inserted into the groove 222 after the screw block 212 is rotated, and the size of the adjusted limiting ring groove 131 can be adapted to the diameter of the preformed armor rod.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
