Description

Hand-held pneumatic tools

The art to which the present invention pertains provides a pneumatic tool, and more particularly a hand held pneumatic tool having an extended section to enhance overall grip and facilitate replacement of the chisel.

Generally, a conventional hand-held pneumatic tool is generally designed to have a handle body, and a handle cylinder is internally provided with a cylinder device, a gas control device for introducing gas into the cylinder device, and a pneumatic device driven by the cylinder device. a rotating impact mechanism, and an output shaft driven by the impact mechanism, and the output shaft is a workpiece such as a hammer, a rust remover and a scraper, but the handle body has no relative body in its structural design. The design is for the position of the user's finger support, so that the user can only hold the handle body when using it, and the position of the finger can not effectively support the positioning, which may cause the problem of insufficient overall grip force, or When replacing the output shaft workpiece, the handle body is usually held by one hand, and the output shaft workpiece is replaced by the other hand, and the insufficient grip of the whole hand when holding with one hand may cause replacement inconvenience.

Therefore, how to improve the above-mentioned missing problems is the technical difficulty point that the creators of this case want to solve.

To achieve the above objectives, the present invention provides a hand held pneumatic tool having an extended section to enhance the overall grip and facilitate the replacement of the chisel.

In order to achieve the above object, the present invention provides a hand-held pneumatic tool, comprising: a handle and a tube body and a joint, wherein the handle has a push switch, and the tube system is disposed on the grip One end of the handle, and the tube body has an extending portion extending horizontally away from the grip direction, the end portion of the extending portion is provided with a cover, and the joint is assembled One end of the extending portion is disposed opposite to the cover, and one side of the joint has a through hole and one end has a set of portions, and a positioning member is disposed in the through hole, and the center of the set portion is The position has a set of holes through the joint, and the set of holes can be assembled with a chisel, and when the user uses his hand-held pneumatic tool, the user holds the handle and presses the pressing on the handle. The switch, and when holding or replacing the chisel, can achieve the effect of improving the overall grip force relative to the setting of the extension section.

The above object of the present invention, as well as its structural and functional features, will be described in accordance with the preferred embodiments of the drawings.

Referring to Figures 1 to 3, it is a three-dimensional group of the preferred embodiment of the present invention. A schematic view and a schematic exploded view and a schematic cross-sectional view of the hand-held pneumatic tool 1 mainly include a handle 2 and a tube 3 and a joint 4, wherein the handle 2 is A pressing switch 21 is disposed at one end, and a cylinder 22 is disposed at one end thereof. The cylinder 22 is sleeved with an actuating member 23, and the tubular body 3 is screwed to one end of the grip 2, and the tubular body 3 is sleeved. The cylinder 22 and the actuating member 23 have an extending portion 31 on the tubular body 3. The extending portion 31 has a width corresponding to the width of the tubular body 3 and the grip 2, and the tubular body 3 is One end of the extending portion 31 is provided with a cover 32. The inside of the cover 32 is formed with a receiving portion 321 at a position opposite to the through hole 41, and a leading edge 322 is formed on a side of the receiving portion 321 and The outer surface of the extending portion 31 is horizontally extended to the outer surface of the cover 32, and the joint 4 is screwed to the other end of the tube 3, and the joint 4 is oppositely disposed on the The cover 4 has a through hole 41 and a set of portions 42. The through hole 41 is provided with a positioning member 411. The assembly portion 42 has a plurality of holes 421 at the position of the assembly portion 421. The assembly hole 421 can be assembled with a chisel member 5, and the chisel member 5 passes through the assembly hole 421 and the joint 4 and enters the tube body 3 oppositely. The side of the positioning member 411 abuts against the top portion 321 , and the other side abuts against the groove 51 of the chisel 5 and presses the chisel 5 thereof. The joint 4 is sleeved with a spring. The spring end is in contact with the assembly portion 42 and the other end is in contact with the top portion 321 .

Please also refer to the foregoing example diagrams and FIG. 4 to FIG. 6 , which are schematic diagrams of the implementation of the preferred embodiment of the present invention, and the implementation diagram 2 and the implementation diagram 3 , wherein the user uses the hand-held pneumatic tool At 1 o'clock, the user holds the grip 2 and presses the push switch 21 on the grip 2 thereof to make the hand-held pneumatic tool 1 actuate, and when gripping on the grip 2 and the push switch 21, the finger can be Simultaneously placed in its extended section 31, with its extended section The width of 31 is equivalent to the width of the tube body 3 and the handle 2, so that the user can hold the handle 2 while holding the finger on the extension section 31, thereby improving the overall gripping force. The effect is that the outer surface of the extending portion 31 and the outer surface of the cover 32 are horizontally extended to each other so that the user can directly hold the chisel 5 when the user wants to replace the chisel 5 It extends the section 31 and simultaneously pushes the cover 32 with its fingers, and when the cover 32 is pushed, its top portion 321 compresses the spring and simultaneously disengages from its positioning member 411, and it chisel The member 5 is not positioned by the positioning member 411, and the chisel member 5 can be taken out and replaced by the assembly hole 421, and when the cover 32 is released, the spring releases the tension and the cover 32 is released. Pulling back and returning the top holding portion 321 to the hole position, and the positioning member 411 follows the guiding edge 322 and abuts the top holding portion 321 and positions the chisel 5 tightly, thereby achieving It can improve the overall grip and facilitate the replacement of the effect of the chisel 5.

It should be noted that the above is only the preferred embodiment of the present case and is not intended to limit the creation. If the changes made in accordance with the concept of the creation are within the scope of the spirit of the creation, for example, for the configuration or arrangement The type is transformed, and the equivalent effect of various changes, modifications and applications shall be included in the scope of the case and shall be combined with Chen Ming.
