Description
Technical field
The utility model relates to a kind of knob, particularly relates to a kind of knob of pneumatic impact wrench.
Background technology
China is dynamo-electric, the assembling tightening tool of automobile product is also relatively backward at present, the tightening tool of the existing manufacturing, mainly based on manual wrench, cannot adapt to the high-performance of electronic products, highly reliable, the requirement of high safety performance and the needs of automated production now such as automobile.Pneumatic impact wrench is provided with knob, and existing knob structure is single, and its effect is only limitted to gearshift, because its structure is single, easily loses efficacy when changing gear.
Utility model content
The utility model is intended to address the aforementioned drawbacks, and provides a kind of knob of pneumatic impact wrench.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: the knob of this pneumatic impact wrench comprises rotating knob, air discharge duct, pin grooves, seal groove and gear, the top of rotating knob is provided with gear, pin grooves is provided with above described gear, be provided with seal groove above described pin grooves, above described seal groove, be provided with air discharge duct.
The beneficial effects of the utility model are: the structure of the knob of this pneumatic impact wrench is simple, by the shift structure arranged, effectively can control the needs of degree of tightening, simultaneously owing to being provided with air discharge duct, be connected with pneumatic impact wrench pore, ensure its rate of precision.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model another side.
Wherein: 1, rotating knob, 2, air discharge duct, 3, pin grooves, 4, seal groove, 5, gear.
Detailed description of the invention
As depicted in figs. 1 and 2, figure comprises rotating knob 1, air discharge duct 2, pin grooves 3, seal groove 4 and gear 5, and the top of rotating knob 1 is provided with gear 5, is provided with pin grooves 3 above described gear 5, be provided with seal groove 4 above described pin grooves 3, above described seal groove 4, be provided with air discharge duct 5.
Knob is connected with pneumatic impact wrench, pin grooves 3 fixing for whole knob, seal groove 4 is for connecting sealing, ensure the sealing effectiveness of the pressure-air of compression, air discharge duct 2 is connected with the pore of pneumatic impact wrench, controls positive and negative rotation, arranges gear 5 bottom rotating knob 1, when practical operation, select suitable gear as required.
The structure of the knob of this pneumatic impact wrench is simple, by the shift structure arranged, effectively can control the needs of degree of tightening, and simultaneously owing to being provided with air discharge duct, being connected, ensureing its rate of precision with pneumatic impact wrench pore.
