'The industry will rethink the goal of breakthrough and Fang Zhongzhong, Yu Mingshi and design experience, aiming at the manufacturing of the related products: "After detailed design and prudent evaluation, 200934620 will end up The invention is practically applicable. [Summary of the Invention] The main purpose of the workpiece is to provide a torque-adjustable pneumatic tool, and the problem to be solved is for a conventional pneumatic guard structure. It is considered that there is still a problem that the torque is hard to be significantly improved, and the torque state cannot be adjusted and changed. The pneumatic tool has a main body, and the end group is provided with an output shaft assembly, and the main body side is provided with a grip portion. And the air inlet joint has a accommodating space in the main body; the main body accommodating space is provided with a steam house ^ 'the> fly gold strikes the hundred ancient, the 々 々 71 Λ - 鳊 孤 , , , , , , , , , , , , , , , , , , The invention has a rotor; the technical feature of the invention solves the problem, mainly because the cylinder-injury of the cylinder has a plurality of vent holes; and a force adjustment drum is added between the main body accommodating space and the cylinder, The force adjustment drum corresponds to the steam red venting hole, and the air venting hole can only be electrically connected to a pair of venting holes, while the remaining venting holes are adjusted by the torque adjusting drum. The wall of the tube is blocked by the door to close the 'torque adjustment drum side and is provided with a control portion protruding from the outside of the main body for regulating the torque to adjust the rotation angle of the rotating drum; thereby, the innovative and unique design makes the present invention substantially similar to the prior art. The following advantages can be achieved: the rotary drum adjusts the rotating cylinder to make the air venting hole to the different group of venting holes to adjust the torque, because the change is the length of the gas compressed in the cylinder space The longer the stroke length is: the greater the air pressure thrust of the rotor is, the larger the torque is. Therefore, the design of this design will enable the pneumatic tool to achieve the torque state to adjust and change, effectively improve the torque and Practical and progressive control.

The external portion is provided and the control portion 60 is displaceable. The control portion 60 and the elongated opening 15 of the main body 1 are disposed opposite to each other and can be provided with an elastic positioning bead body 70 and a plurality of array positioning edges 71 for adjusting the torque. The rotation of the drum 50 can achieve a compartmentalization effect. Each of the single group of venting holes 41 or 42 or 43 of the plurality of array vents 41, 42, 43 may be formed by a plurality of holes or a single hole. With the above-mentioned structural composition design, the operating state of the present invention is as shown in Fig. 4, which is a schematic diagram of the embodiment of the structure disclosed in the above-mentioned FIG. 3, and the external air pressure w is composed of the main body ίο bottom. The air inlet connector 13 of the end is connected to the internal intake air passage 16 and the forward and reverse switching unit 17 and then introduced into the cylinder 20 through the air inlet hole 24 on the upper side of the end cover 22 to drive the rotor 30. Then, the air pressure W will be The exhaust hole 41 (or 42, 43) provided on the lower side of the cylinder 21 of the cylinder 20 is discharged, and is further discharged to the outside through the exhaust flow path 18 provided by the main body 1 〇 grip portion 12 and the muffler gas 19. In the figure, the user can easily adjust the rotation angle of the torque adjustment drum 5〇 according to the fifth control unit 60, thereby improving the air vent 51 and the vent holes 41 and 42 provided in the cylinder 21. In the case of the slanting bears of the present embodiment, the three types of venting holes 41, 42, 43 are provided in the embodiment, and the fifth embodiment is shown in the damper portion 6 to constitute the venting hole 5 When the control unit is pulled to the left end of the figure (as shown in FIG. 6), the air venting hole 51 and the right side venting hole 42 are formed. When the control unit 6 is pulled to the right end of the figure (as shown in FIG. 7), the state in which the air perforating hole 51 and the left side exhaust hole 43 are electrically connected to each other is formed; By the different air venting holes 41, 42 and the symmetrical alignment state of the air venting hole and the rainbow tube 21, the main cymbal can change the length of the stroke after the air pressure W enters the cylinder tube 21 to the discharge. The torque of the rotor 30 can be changed. When the pressure W is relatively long, the driving force of the rotor 3 is increased. To increase the torsion force: on the contrary, when the stroke of the air pressure W is relatively short, the torque t of the rotor 3〇 is low; the user can adjust the characteristic by the characteristic to respond to the state of the state 1 x the rotor 30 When the reversing mode is used to loosen the bolt, it will need to be achieved with the twisting force. At this time, the old one can be used for a longer period of time; and the rotating force of the rotating drum 50 can only be low-torque. When the turning mode is reached and the bolt is tightened, the temple can adjust the torque adjustment drum 50 9 200934620 in the shorter stroke position. (Note: The upper diagram in Figures 5, 6, and 7 is the top view of the position of the elastic positioning bead 7〇 and the positioning edge 71 of the elongated mouth 15 corresponding to the control unit 6〇 of the following figure) As shown in FIG. 9 and FIG. 9, the intake hole 24 may also be disposed at the lower side of the cylinder 2 end cover 22. The exhaust holes 41, 42 and 43 are disposed at the upper side of the cylinder 21 of the cylinder 2, Thereby, a flow path type of the lower intake air and the upper exhaust air is formed; and the state of the air pressure integral flow path of this embodiment is as shown in FIG. 9 , and the external air pressure W is the air intake of the bottom end of the main body 1 The joint 13 is introduced, and is passed through the inner 〇°卩 intake passage 16 and the forward/reverse switching unit 17 and then introduced into the cylinder 20 by the intake hole 24 on the lower side of the end cover 22 to drive the rotor 3〇, and then the air pressure ν will be from the cylinder. The vent hole 41 (or 42, 43) provided on the upper side of the cylinder tube 21 is discharged, and is further discharged to the outside by the vent hole provided in the control portion 60 on the top side of the main body 10 or the vent hole provided in the dome side of the main body 1. Advantages of the Invention: The invention mainly adopts an innovative and unique design of adding the torsion adjusting drum and setting a plurality of Μ venting holes, and adopting a rotating torque to adjust the rotating cylinder to make the air venting pair switch between different groups of venting holes. To achieve the purpose of adjusting the torsion, since the change is the length of the stroke in which the gas is compressed in the cylinder space, the longer the stroke length, the greater the air pressure thrust of the operation of the rotor, so the torque S is large; Therefore, the design of this creation will enable the rolling tool to reach the torsion state to be surely adjusted and changed, effectively improve the torque and control convenience, and more suitable for the practical progress required by the user.
