Problems solved by technology
Although this solves the problem of manual access to the screws to a certain extent, the screws are easily dropped from the screwdriver, which creates new technical problems
In particular, with the use and popularization of automation equipment, automatic screw locking machines are gradually used in production. The automatic locking screw machine uses the manipulator to take the screws, and the screws are easy to fall off.

The invention provides an anti-disengagement screw. The anti-disengagement screw comprises a screw assembly and an anti-disengagement assembly; the screw assembly comprises a screw and a screw cap, the screw cap is provided with a screw hole penetrating through the upper end face and the lower end face of the screw cap, the tip of the screw penetrates through the screw hole to stretch out of the screw cap, and the flat end of the screw is clamped into the screw hole; the anti-disengagement assembly is provided with an inserting piece, an elastic piece and a pressing piece; the inserting pieceis provided with a through inner cavity hole, one end of the inner cavity hole is provided with an inserting end, and the inserting end is inserted into the screw hole and provided with a hole; the elastic piece is arranged in the inner cavity hole of the inserting piece and can penetrate through the hole to be in clamping connection with the screw hole; and the pressing piece is arranged on the inserting piece and pushes the elastic piece to ascend and descend in the inner cavity hole of the inserting piece, so that the elastic piece is clamped to or disengaged from the screw hole, and the anti-disengagement assembly is connected with or disengaged from the screw assembly.
Description
technical field [0001] The invention relates to the technical field of screws, in particular to a fall-off prevention screw. Background technique [0002] Screws are used to fix connected objects and are widely used in various mechanical equipment. A conventional screw structure includes a nail body, a tip and a flat end positioned at two ends of the nail body. The flat end is usually provided with a straight or cross-shaped groove, which facilitates the installation and removal of screws by a screwdriver. However, when this screw is installed, it is taken by hand, and the tip of the screw is relatively sharp, which often punctures people's hands. In order to solve this technical problem, people add magnetism on the top material of screwdriver, take screw by magnetic force adsorption. Although this solves the problem of manually taking the screw to a certain extent, yet the screw is very easy to drop from the screwdriver, which has created new technical problems. In part...
