Description

Manual type motor tire wrench for dismounting

A kind of manual type motor tire wrench for dismounting belongs to the hardware ﹠ tools technical field, the spanner that uses when relating to a kind of dismounting motor tire.

The existing instrument that is used for motor tire dismounting use has electrodynamic type, steam-operating formula Screw setting and loosening machine device, only just disposes in repairing place of specialty.And be the manual type spanner with the instrument of car, be telescoping structure, an arm of force is arranged, because the screw of motor tire is fixing tighter, need the lengthening arm of force, and be difficult to looseningly, dismounting is wasted time and energy.And

The purpose of this utility model provides a kind of manual type motor tire wrench for dismounting of the conveniently detachable motor tire that uses with car.To overcome the deficiencies in the prior art.

The purpose of this utility model is finished like this: it has an overcoat that has an arm of force, suit inner core in the overcoat, on the ring inner core caulking groove is arranged, gear is installed in the caulking groove, the center mounting teeth wheel shaft of inner core, gear matched in gear wheel shaft and the caulking groove, gear matches with the internal tooth of outer casing inner wall, is screw socket at an end of the relative mounting teeth wheel shaft of inner core.
