Abstract
The utility model relates to an anti-theft nut and a special spanner for vehicle wheels. The nut is made from medium carbon steel, wherein the exterior of the nut is cylindrical, an inner hole of the nut is step-shaped, a small hole at the left side of the nut is a screw hole, and a big hole at the right side of the nut is an internal splined hole. The special spanner is made from tool steel, wherein the appearance of the special spanner is T-shaped, the upper part of the special spanner is provided with a cross bar which is used for applying a force by both hands when the nut is mounted/dismounted, a cylindrical external splined sleeve is arranged at the lower end of a vertical bar at the lower part of the special spanner, the internal hole of the external splined sleeve is a round hole, the internal diameter of the round hole is larger than the nominal diameter of the nut, a spline is formed in the surface of an external cylinder of the external splined sleeve, and the external diameter, tooth form and number of teeth of the external splined sleeve are matched with those of the splined hole of the anti-theft nut. When the special spanner is used, the external splined sleeve at the lower end of the special spanner is inserted into the splined hole at the right side of the anti-thief nut, and the anti-theft nut can be driven to rotate through pulling the cross bar. The anti-theft nut and the special spanner for the vehicle wheels have the beneficial effects that the use is convenient and rapid, the vehicle wheels have less possibility of being stolen, and the popularization is easy.
Description
Technical field
