The housing (12) uses the liquid-dust principle to output power to the head. (1)), a drive shaft (14) is rotated by a steering mechanism. The built-in power hydraulic output of the housing (12) can be adjusted as long as the outer screw cap (15) is loosened, and the __polygonal wrench (16) is inserted into the screw cap (15) as shown in the second figure. The gap between the housing (12) is then rotated by a wrench (16) to search for the adjustment knob (17). Since the screw cap (15) abuts (4) U3) and the gap between the wall surface of the casing (12) can only allow the wrench (16) to protrude without being able to visually search the adjusting knob 7), the wrench (16) touches the adjusting button. (17) The search process for inserting holes into positions is very difficult and time-consuming is relatively extended. The applicant of this case developed a pneumatic tool adjustment structure to solve the above drawbacks. [Invention] One of the objects of the present invention is to provide an adjustment structure for a pneumatic tool, which is provided with a hole in the periphery of the adjustment button. The wall of the pneumatic tool has a hollow window at a position relative to the adjustment button, and the window is used for use. 5 1327945 Adjust the button hole of the button to easily find the adjustment button, and use the wrench to insert the hole through this window for the torque value adjustment. In order to achieve the above object, a pneumatic tool adjusting structure of the present invention is to lock a head to a hollow tubular casing by a screw cap, and the casing is integrally connected with a body-joining member. A pneumatic mechanism driven by external high pressure gas transmits kinetic energy to a power hydraulic mechanism located in the housing. The power hydraulic mechanism has a drive shaft that drives a drive shaft located at the head to rotate.

The gas input body (3〇) internal air pressure mechanism (21) is converted into kinetic energy, and transmitted to a dynamic hydraulic mechanism (22) inside the casing (32), and the power liquid f mechanism (22) outputs an adjustable Power, a drive shaft exposed through a steering mechanism (23) π moving head (34) (24) Rotate while achieving the output of the torque. 6 1327945 From the third and fourth figures, the power hydraulic mechanism (22) resembles a circle. The cylindrical object protrudes from the axial direction at one end with a drive shaft (40) • and a circumferential integral ( 4))' and a flange (42) is formed around the end, the flange (42) having a notch (43) relative to the position of the adjustment knob (41). Wherein, the adjusting button (41) is provided with an insertion portion (44) around the insertion portion (44), which may be a through hole or a recessed groove. The housing (32) has a hollow tubular shape that allows the aforementioned power hydraulic mechanism (22) to penetrate into the housing (32) with one end of the drive shaft (40). The shell body (32) is rotatably coupled to the coupling member (31) to project two symmetrical projections (50) on the end faces.
