Title:
SCREW FIXING ASSISTANCE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/222681
Kind Code:
A1
Abstract:
A screw fixing assistance apparatus, comprising a sleeve rod (100). The sleeve rod (100) has a hollow inner cavity, and is filled with a protective agent that can form a protective layer on the surface of a screw. A front end (110) of the sleeve rod (100) is used for mounting a screw head, and the front end (110) is provided with a flow channel (200) communicated with the hollow inner cavity. A rear end (120) can be connected to a rotating end of a screwing tool, and can cause the sleeve rod (10) to synchronously rotate with the rotating end. When the sleeve rod (100) rotates, the protective agent flows through the flow channel (200) to a screw side. When the screwing tool drives the sleeve rod to synchronously rotate to screw a screw into a member to be fixed, the protective agent flows from the hollow inner cavity to the screw side through the flow channel, and is distributed on the surface of the screw head to form a new protective coating, thereby effectively protecting the screw, and improving the corrosion resistance and the usage safety of the screw.
