Technical field
It the utility model is related to a kind of switching device, more particularly to a kind of pneumatic tool inlet air switching device.
Background technology
When using instrument is turned round surely, the difference of corresponding station, or emergency situations are run into, it is necessary to tighten or unscrew screw, also
There is situation about not withdrawn in place when tightening screw exactly just to need to tighten and unscrew function and all possess.Big department's work on the market
Tool is the purpose for reaching commutation by rotary knob, or rotating ring, but a disadvantage is that bimanualness is wanted, but in streamline
On, operator needs to take screw etc., can not liberate an other hand, one-handed performance is just into advantage.
The content of the invention
The utility model is to avoid above-mentioned the shortcomings of the prior art part, there is provided an a kind of pneumatic tool air inlet switching
Device, the structure switched using rotating, improve productivity ratio, facilitate the singlehanded commutation of worker.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of pneumatic tool inlet air switching device, including：
Housing, change-over key, copper sheathing, base, motor rear end lid, commutation pad, spring and joint；
Change-over key can be vertically arranged on housing up or down, and the change-over key includes the valve head of cone, post
The valve rod of shape and the first commutation side and the second commutation side being arranged on valve rod；
Copper sheathing is arranged on the circumference of change-over key and seals against connection；
Spring is connected with the second commutation side bottom of change-over key valve rod；
Copper copper sheathing side is connected with motor rear end lid, and motor rear end cover rim axle center and rotating forward air inlet is respectively symmetrically distributed with
With reversion air inlet；Commutation pad is provided with motor rear end lid end face；
Copper sheathing opposite side, base is distributed with along the lumen circumference of housing, base one end flushes with the axial end of housing, connect
Head is arranged on housing end face, and the flange part of joint is supported in the outer face of housing shaft end.
Improvement to above-mentioned technical proposal：Copper sheathing is made up of tin bronze material.
Improvement to above-mentioned technical proposal：The pad that commutates is made from metal.
The beneficial effects of the utility model are：By setting change-over key to coordinate spring, it singlehanded can commutate, easily change
To and can pinning and rotate backward, press down rotation, it is possible to pin, can also crawl commutation, the reversion of short time, press
Once invert, it is to rotate forward again to unclamp.
Brief description of the drawings
Fig. 1 is the schematic diagram that pneumatic tool inlet air switching device of the present utility model rotates forward state.
Fig. 2 is the schematic diagram of pneumatic tool inlet air switching device inverted status of the present utility model.
Fig. 3 is the structural representation of this practical change-over key.
Shown in figure：1. change-over key, 2. copper sheathings, 3. bases, 4. motor rear end lids, 5. commutation pads, 6. bullets
Spring, 7. joints, 8. valve heads, 9. valve rods, 10. first commutation sides, 11. second commutation sides, 12. housings, 13. just rotate into

Embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
As Figure 1-3：A kind of pneumatic tool inlet air switching device, it is characterised in that including：
Housing 12, change-over key 1, copper sheathing 2, base 3, motor rear end lid 4, commutation pad 5, spring 6 and joint 7；
Change-over key 1 can be vertically arranged on housing 12 up or down, and the change-over key 1 includes the valve head of cone
8, the valve rod 9 of column and the first commutation side 10 and the second commutation side 11 that are arranged on valve rod 9；
Copper sheathing 2 is arranged on the circumference of change-over key 1 and seals against connection；
Spring 6 is connected with the bottom of the second commutation side 11 of change-over key valve rod；
The side of copper sheathing 2 is connected with motor rear end lid 4, and motor rear end cover rim axle center and rotating forward air inlet is respectively symmetrically distributed with
13 and reversion air inlet 14；Commutation pad 5 is provided with the end face of motor rear end lid 4；
The opposite side of copper sheathing 2, the shaft end of base 3, the one end of base 3 and housing is distributed with along the lumen circumference of housing 12
Face is flushed, and joint 7 is arranged on housing end face, and the flange part of joint 7 is supported in the outer face of housing shaft end.
Improvement to above-mentioned technical proposal：Copper sheathing 2 is made up of tin bronze material.
Improvement to above-mentioned technical proposal：The pad 5 that commutates is made from metal.
