Description

Pneumatic tool

Technical field

Utility model relates generally to a kind of pneumatic tool, refers to a kind of pneumatic tool applicable to various different sleeve dimensions especially, and it is involved in air tool technical field.

Background technology

The hand-held tool of air driven mode can be used to elements such as bolt or nut are carried out that pine moves back or fastening action, quite fast convenient, therefore the application of such hand-held tool is very wide at present, wherein as shown in Figures 7 and 8, pneumatic tool an ancient unit of weight consists predominantly of a housing 41 and one and the sleeve 42 that is screwed of housing 41, these sleeve 42 outsides are equipped with a pore 421, make the gas in the housing 41 can leak to the outside via the pore 421 of sleeve 42, be directly injected into the user for fear of the gas that leaks, general pneumatic tool 40 can take shape in sleeve 42 with pore 421 and be stretched on the end of housing 41 inside, the gas that releases can be sprayed forward along housing 41, and can not be directly injected into the user;

Because air tool housing 41 is a fixing structure kenel, therefore need to cooperate specific sleeve 42 to use to avoid pore 421 to be exposed to housing 41 outsides, so when the user desires big power output and when needing to change the long sleeve of length, the user often need buy a housing in the pore than long sleeve can being coated in addition and be used, therefore not only can bring inconvenience to the user, also can increase the required cost of user relatively, and producer's housing of also needing the sleeve manufacturing according to various different sizes be consistent.

Novel content

Therefore, utility model is in view of deficiency and defective in existing pneumatic tool structure and the use, and continuous test of special process and research develop the utility model that the existing defective of a kind of energy improvement finally.

The main purpose of utility model is to provide a kind of pneumatic tool, and it effectively increases air tool applicability applicable to the pneumatic tool of various different sleeve dimensions, reaches handled easily and cost-effective purpose.

For achieving the above object, utility model mainly provides a kind of pneumatic tool, and it includes a housing, and extends the collar and a sleeve, wherein:

Housing is provided with the room of a hollow, and this room is provided with an openend and a blind end, and inwardly convexes with an internal thread between openend and blind end;

Extend the collar and be and removably fasten with housing and be connected with room, this extension set is equipped with a joint portion and an extension; And

Sleeve with extend the collar and housing combines and be connected with room, this sleeve is stretched at an end that extends the collar and housing and is provided with an external screw thread that is screwed with the housing internal thread, and is being equipped with a pore that is connected with sleeve inner near on the externally threaded sleeve.

By above-mentioned technological means, advantage that the pneumatic tool of utility model can obtain and effect enhancement comprise at least:

One, applicability height: the use that can be by the loading and unloading of extending the collar combines of the pneumatic tool of utility model with the sleeve of different size, do not need to buy in addition again a housing that conforms to sleeve, effectively improve air tool applicability.

Two, handled easily: the pneumatic tool of utility model only needs the extension collar to be combined with housing by the engaging of joint portion and openend, and is quite convenient in the use.

Three, save cost: the pneumatic tool of utility model, need not buy or make the use that can combine with the sleeve of different size of another housing, reach cost-effective purpose.

Embodiment

Utility model mainly provides a kind of pneumatic tool, please cooperate referring to Fig. 1 to Fig. 4, and by seeing among the figure, the utility model pneumatic tool is provided with a housing 10, and extends the collar 20 and a sleeve 30, wherein:

Housing 10 slightly is a rifle shape structure, its level to inside be the room 11 of a hollow, this room 11 is provided with an openend 111 and a blind end 112, and inwardly convexes with an internal thread 113 at openend 111 and 112 of blind ends;

Extending the collar 20 is and removably fastens with housing 10 and be connected with room 11, this extension collar 20 is provided with a joint portion 21 and an extension 22, wherein joint portion 21 is stretched in the room 11 of housing 10 and fastens with openend 111, and joint portion 21 inner edge surfaces are provided with an internal thread 211 directly identical with housing 10 rooms 11 internal threads 113 spiral shells, and extension 22 differs from openend 111 1 ends with joint portion 21 and combines; And

Sleeve 30 with extend the collar 20 and housing 10 combines and be connected with room 11, this sleeve 30 be stretched at an end that extends the collar 20 and housing 10 be provided with one with extend the external screw thread 31 that the collar 20 and housing 10 internal threads 211,113 are screwed, and be equipped with a pore 32 that is connected with sleeve 30 inside near on the sleeve 30 of external screw thread 31, other combines with a switching valve 50 at the end that sleeve 30 is provided with external screw thread 31.

Thus, as Fig. 5 and shown in Figure 6, when using short sleeve 30, the user only needs sleeve 30 ' and housing 10 are screwed and pore 32 ' can be located in housing 10 inside, and the gas that releases can be sprayed forward along housing 10;

And when the big power output of needs, then need use long as shown in Figure 1 sleeve 30, after the joint portion 21 that this moment, the user then needed to extend collar 2O fastens with the openend 111 of housing 10, to combine and to use with the housing 10 and the extension collar 20 than long sleeve 30 again, gas in the housing 10 can be sprayed forward along extending the collar 20 via the pore 32 of sleeve 30, and can not be directly injected into the user, and then it is outer and spray situation in the user effectively to avoid pore 32 than long sleeve 30 to be exposed to housing 10, effectively increase air tool applicability, and do not need additionally to buy another housing 10, and the producer does not also need the sleeve 30 according to various different sizes, 30 ' and make the housing 10 of different size, reach handled easily and cost-effective pneumatic tool.
