The invention discloses a screw with high drilling thoroughness, which comprises a screw body. A screw cap is arranged at the upper end of the screw body; a screw rod is arranged at the lower end of the screw cap; the upper end of the screw rod and the screw cap are connected and fixed; the lower end of the screw rod is in a cone shape; the outer side end face of the screw rod is a smooth surface; a plurality of cone spines are arranged on the outer side end face of the screw rod, and protrude out of the outer side rod face of the screw rod; each cone spine is vertically downward to form a cone-shaped body; and a filling cavity is arranged in each cone spine, and is filled with an elastic rubber material. Through the manner, the drilling thoroughness of the screw body can be improved, and the cone spines on the outer side rod face of the screw rod can be more beneficial for the screw body to be hammered into an object, so that the work efficiency is greatly improved.
Description
technical field [0001] The invention relates to the field of screws, in particular to a screw with high drilling performance. Background technique [0002] The screw is to screw the thread directly into the threaded hole of one of the connected parts. It does not need to use a nut. The connection method is fast and easy. There are many types of screws, such as machine screws, self-tapping screws, drilling screws, wallboard screws, and fiberboard screws. , wood screws, hexagonal wood screws, non-protruding screws, combination screws, miniature screws, furniture screws, electronic screws, and chain strap screws are all types of screws. Although the traditional screw connection method is fast, it still needs to be improved in terms of penetration. The traditional screw cannot be introduced into the hard plate very well and quickly, and the resistance encountered during screwing cannot be overcome well. Contents of the invention [0003] The technical problem mainly solved by...
