Description
Technical field
The present invention relates to a kind of tire remover, particularly relate to a kind of pneumatic impact wrench servicing unit.
Background technology
Service a car wheel time, tire must be removed from automobile, and dismounting wheel nut is time saving and energy saving, this is a headachy problem.
At present, in the following method dismounting is carried out to the nut on wheel: namely directly with manpower portable special wheel dismounting pneumatic impact wrench, dismounting is carried out to wheel nut.Because pneumatic impact wrench is heavier, and vibrations very go through evil when dismounting, so portable pneumatic impact wrench disassemble and assemble work efficiency is low, work is extremely difficult and feel bad, larger to the damage of human body.
In addition, because portable pneumatic impact wrench easily makes people tired, easily occur not tight when loading nut, or locking force is uneven.Like this, in the process of moving, loosening easily appears wheel in nut, thus result in the generation of accident.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of pneumatic impact wrench servicing unit, this pneumatic impact wrench servicing unit can convenient, fast, safely dismounting operation is carried out to the nut on wheel.The technical scheme adopted is as follows:
