Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, fig. 2 and fig. 3 below, a conical screw comprises a screw body 1, wherein a conical head 2, a conical rod 3 and a conical base 4 are arranged on the screw body 1, a spiral slice 5 which can be cut is arranged on the outer surface of the conical rod 3 in a surrounding manner, the conical rod 3 is connected with the conical head 2 in a welding manner, and the conical base 4 is fixed at the bottom of the conical rod 3 in a welding manner.

The outer surface of the conical head 2 is provided with spiral threads 6, the tail end of the conical head 2 is provided with a round fixing block 7, and a fixing rod 8 is arranged below the round fixing block 7.

In this embodiment, the spiral slice 5 arranged on the tapered rod 3 is mainly used for cutting, can cut rapidly, has high strength, strong abrasion resistance and strong corrosion resistance, and effectively prolongs the service life of the tapered head 2.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
