Abstract

The invention provides a screw limiting device. A screw casing pipe and handrails are included. The handrails are symmetrically arranged on the outer surface of the screw casing pipe. The screw casingpipe is a hollow cylinder and comprises an upper casing pipe body and a lower casing pipe body. Connecting mechanisms are arranged at the two ends of the upper casing pipe body and the two ends of the lower casing pipe body. The inner surface of the screw casing pipe is provided with a plurality of springs and a plurality of protruding heads, and the springs are fixedly arranged on the multiple protruding heads. Each connecting structure comprises a pull rod, a groove and a plug. The grooves are located in the upper casing pipe body, the pull rods are located in the grooves, one ends of the pull rods are located in the upper casing pipe body, the other ends of the pull rods are located in the lower casing pipe body, and fixing and limiting are achieved through the plugs. A screw locator is not prone to deformation, and the function of screw limiting is achieved.

Description

technical field [0001] The invention relates to the technical field of hardware and building materials, in particular to a screw limiting device. Background technique [0002] Screws are common in machinery, electrical appliances and buildings, and are widely used; in the prior art, in the process of nailing screws, there are often situations of screw fixing tilt and inconvenient operation, and the present invention improves on this problem. Contents of the invention [0003] In view of this, the present invention aims to overcome the defects in the above-mentioned prior art, and propose a positioner with a simple structure and capable of fixing screws. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A screw limiting device, comprising a screw sleeve and a handrail; the handrail is symmetrically arranged on the outer surface of the screw sleeve; [0006] The screw sleeve is a hollow cylinder, in...
