The housing (12) uses hydraulics to output power to the head (13). ), a drive shaft (14) is rotated via the steering mechanism. The power liquid (four) wire built into the casing (12) can be adjusted 'just loosen the outer screw i (15)' as shown in the second figure, a polygonal wrench (16) is inserted into the screw cap (15) and the shell In the gap of the body (12), after turning the wrench U6), the search adjustment button (17) is rotated. Due to the gap between the head (13) of the screw cap (15) 5 and the wall surface of the housing (12), only the wrench (16) can be allowed to protrude without being able to visually search for the adjustment knob 7), so the lever = touch (9) position The process of searching for holes is not difficult. The aging is relatively long. The above is a research and development of a pneumatic tool adjustment structure to solve the above drawbacks. SUMMARY OF THE INVENTION The object of the present invention is: in: for the pneumatic tool lifting, is to adjust (4) the peripheral design has a hole, the pneumatic tool wall 3 This adjustment (four) position has a hollow shape (four), through this window to let use ^ 200932437 It is easy to find the adjustment button, and use the wrench to insert the adjustment hole of the window to adjust the torque value. To achieve the above object, a pneumatic tool adjusting structure of the present invention is a m-head-locking-hollow tubular casing which is coupled to a body. The device is integrally connected, and the body has a pneumatic mechanism driven by external high-pressure gas, and transmits kinetic energy to a power hydraulic mechanism located in the housing. The power hydraulic mechanism has a transmission shaft, and the transmission shaft drives a head. The drive shaft rotates. The power hydraulic mechanism surrounds the outer side of the transmission shaft with a ring flange, and the portion of the edge adjacent to the transmission shaft has a tuning button for controlling the power value of the transmission shaft. The flange has a position relative to the position of the adjusting button. σ is absent; the outer f of the casing forms a complex f-bit stratum, wherein the stratum stratum is provided with a ring corresponding to the notch, and is screwed against the bit stratum of the casing having a window, and the f-ring wall penetrates There is an outer hole that faces the window as the collar rotates. [Embodiment] Referring to the third figure, the figure shows that a pneumatic tool (2〇) connects a body (3〇) and a casing (32) together by a coupling member (31), the casing ( 32) The lock is integrated with a head (34) via a screw cap (33). The body (30) is connected to the external pneumatic power source, converts the external high-pressure gas into the body (30), and the air pressure mechanism (21) converts the kinetic energy into a dynamic hydraulic mechanism (22) inside the casing (32). The power fluid, the mechanism (22) outputs an adjustable power, and a steering shaft (24) exposed by the head (34) is rotated by a steering mechanism (23) to simultaneously achieve the output of the torque. 6 200932437 From the third and fourth figures, the power hydraulic mechanism (22) is similar to a round-shaped object. A drive shaft (4〇) and an adjustment knob (41) protrude from the surface at one end along the axial direction. And a flange (42) is formed around the end, and the flange (42) has a notch (43) with respect 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 body (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 housing ◎ body (32) is rotatably coupled to the coupling member (31) to project two symmetrical projections (50) on the end surface. The head (34) is provided on the end face with two symmetrical grooves (51) which are opposite to the projections (50) on the casing (32) passing through the collar (35) and the cap (33). Docking each other, and then rotating the screw cap (33) to assemble the two components. The outer wall of the casing (32) forms a complex layer (52), and the layer (52) adjacent to the bump is designed with a hollow window (53), and the sleeve (33) is held by the screw cap (33) against the shell. The body (32) has a bit level (52) of the window. As seen from the fifth figure, the cap (33) and the housing (32) are locked, and the collar (35) is rotated to a predetermined angle, and the outer hole (36j is just opposite the stratum level (52). Circumferential surface. When the power output value needs to be adjusted to change the torque output, turn the collar (%) as shown in the sixth figure to make the outer hole (36) face the window (53) of the positive level (52). The window (53) and the power hydraulic mechanism (22) are disposed on the flange (42): (43), so that the user can quickly and easily visually search the position of the adjustment button (41), thus, It is very easy to pry the wrench or elongated object into the insertion part (44) to quickly turn the adjustment knob (41). After the adjustment of the force value 200932437, turn the collar (35) to another angle again, close the window. (53) To achieve the purpose of masking the adjustment knob (41).
