Abstract
The invention discloses a combined screw, which comprises a screw tip, a screw rod, a screw cap and a connecting screw. The combined screw comprises the screw tip, the screw rod and the screw cap, wherein the screw tip, the screw rod and the screw cap are integrally molded, a threaded hole is formed in the middle part of the screw cap, and the connecting screw is arranged at the inner part of the threaded hole. Through the mode, the combined screw disclosed by the invention has a simple structure and comprises two screws, so that a slot of a traditional screw can be replaced, and the screw is more convenient to assemble.
Description
