The first chamfer and the second chamfer are used to assist the push column in pushing the slider. After the glue capsule is squeezed, the glue flows out from the liquid outlet groove and flows into the liquid flow groove from the gap between the smooth surface and the object, so as to fill the gap between the object and the fixing strip with glue. The fixing strip is not parallel to the lower thread and the upper thread, which can further prevent the screw from falling off.

[0006] Preferably, the top end of the liquid outlet trough is located at the lower end of the chute.

[0007] Beneficial effects of the utility model:

[0008] 1. By setting up a bidirectional thread anti-rotation mechanism and a glue containing mechanism, after the screw is embedded in the object, the two sets of stripe structures with different angles can prevent the screw from rotating outwards, and the glue overflowed due to extrusion fills the gap between the screw and the hole of the object to further fix the screw and the object together, thereby preventing the screw from falling off, and the anti-rust coating on the surface of the screw prevents erosion from the outside to extend the service life of the screw;

[0009] 2. Insert the hexagonal screwdriver into the hexagonal slot and turn the screw to embed it into the object. After the screw is embedded into the object, the lower thread and the upper thread are used to prevent the screw from slipping off, and the soft pad is used to fill the gap between the fixing plate and the object to increase the friction between the screw and the object. The hexagonal slot prevents the screw from being easily worn due to thread slipping when the user is tightening the screw. After the screw is fixed, insert the cross screwdriver into the cross slot to rotate the internal thread column in the internal thread groove, so that the push column is pushed inward, thereby pushing the slider outward, and the push column squeezes the glue capsule. After the slider is pushed outward, because the fixing bar is not parallel to the lower thread and the upper thread, it can prevent the screw from rotating outward and causing the screw to fall off;

[0010] 3. After the glue capsule is squeezed and broken, the glue flows out from the liquid outlet groove and flows into the liquid outlet groove from the gap between the smooth surface and the object, so as to fill the gap between the object and the fixing strip with glue, so as to further fix the screw and the object together, thereby further preventing the screw from falling off.
