Abstract

The utility model relates to a special force application wrench for dismounting tire in the field of garage tool, which comprises a socket and a handle; the outer end of the handle is provided with a diameter-expanding cone; a bush is sheathed outside the handle; the inner end of the bush is provided with a diameter-reducing conical cavity; the conical surface of the conical cavity matches with the cone of the handle. The bush is sheathed on the base of the original handle in the utility model; in this way, the bush on the handle is integrally carried, thus being conveniently used; the most important point is as follows: the length of the handle can be directly lengthened through pulling the bush, thus improving the acting force of the wrench for being used under special situations.

Description

The special use of dismounting tire adds torque wrench

Technical field: a kind of dismounting tire special use that the utility model relates to the car repair tool field adds torque wrench.

Background technology: the spanner of dismounting tire normally is made up of with the handle overall structure pullover at present, because overall construction design causes the limited length of handle, in addition along with the with the passing of time corrosion of tire hold-down nut, especially large car tire, original tyre wrench has been difficult to satisfy use, usually need be inserted in the prolongation handle by steel pipe, reach the requirement of dismounting.

The utility model content: the purpose of this utility model is exactly the defective that exists at prior art, provides a kind of simple and practical dismounting tire special use to add torque wrench.

Its technical scheme is: comprise pullover and handle, be provided with the cone of hole enlargement in the outer end of handle, handle jacket has sleeve pipe, and sleeve pipe the inner is provided with the awl chamber of undergauge, and the conical surface in awl chamber forms with the cone of handle and cooperates.

The utility model overlaps tubing on the basis of original handle, sleeve pipe one on handle is carried like this, and is easy to use, most importantly by stretched sleeve pipe, the length that can directly add long handle, the active force of raising spanner is to satisfy use in particular cases.

Description of drawings: accompanying drawing is the structural representation of a kind of embodiment.

The specific embodiment: with reference to accompanying drawing, pullover 1 and handle 2 constitute existing tyre wrench, on this basis, the outer end of handle 2 is provided with the cone 3 of hole enlargement, handle jacket has sleeve pipe 5, and sleeve pipe 5 the inners are provided with the awl chamber of undergauge, and the conical surface 3 in awl chamber forms with the cone of handle 3 and cooperates.

During use, generally, sleeve advances between pullover and cone, when strengthening strength if desired, pulls out pullover, and the inner conical surface of sleeve combines with the Outer Taper of handle, is equivalent to prolong the length of handle.
