The rotating member 5 is rotated. The elastic member 26 can be a spring. The elastic member 26f can be disposed in a connecting portion 63 of the rotating button 60 and a shoulder 63 and a trigger 6 The inner side is assembled between the inner ends of one of the sleeves 64. With the above structural design, the operation of the present invention will be described as follows: As shown in FIG. 5 (and please cooperate with FIG. 3), when the user presses the trigger 16 of the pneumatic tool, the switch stem will be driven. 22 moves inwardly, causing the dense ring portion 223 to be removed to release, so that the air pressure of the air inlet channel 12 can enter the throughflow space 33 of the switching drum 30; and at this time, if the switching coil is 1 Rotating to a first predetermined angle, the first air venting hole 31 is configured to communicate with the forward air guiding hole 23 of the valve body 21 (refer to FIG. 6), and the top end of the venting groove 34 and the valve body When the reverse intake air guide hole material is in the state of the positional communication, the aforementioned introduction air pressure W1 will pass through the through space, the perforation 53 of the rotary seat 50, the first air supply hole 31 of the switching drum 3, and the valve main (4) Turning the air intake guide hole 23 and the forward guide flow path 13 into the action of the pneumatic tool 1〇, the rotor is rotated in the forward direction (as indicated by the arrow R1 in Fig. 6). After the exhaust gas flow after the rotor n is pushed out, the old exhaust pipe 17 is discharged, and then the reverse flow guide will be sequentially passed. 14. Reverse direction of the valve body 21 200824851 The hole guide hole 24, the exhaust guide groove 34 of the switching drum 30 is discharged to the outside by the pain port 25 of the valve body 21; the material 'this state is the intake pressure through which the rotation The flow rate (ie, the torsion) of the perforation provided in the hollow cavity can be adjusted. As shown in Figures 7 and 8 (and please cooperate with Figure 3), when the user wants to switch the rotor 11 to rotate in the reverse rotation state, the steering switch 40 of the steering switch mechanism is operated to reverse the operation. The switching drum 3 is rotated to a second predetermined angle, so that the second air vent 32 and the reverse air guiding hole 阀 of the valve body 21 are in positional communication, and the top end of the venting groove 34 and the wide body 21 are forward. When the intake guide hole 23 is in the position of the opposite position, the aforementioned pilot air pressure W1 will sequentially pass through the through space 33, the second air vent 32 of the switching drum 3, the reverse air intake guide 24 of the valve body 21, and the reverse The guide channel 13 enters the action of the pneumatic jade 1,, so that the rotor 11 is in a reverse rotation state (such as the month in Fig. 8, No. J, R2), and the exhaust airflow W2 after the rotor 11 is pushed. After the cylinder 17 is led out, the exhaust guide channel 24 of the valve body 21, the reverse exhaust guide hole 24 of the valve body 21, and the exhaust port 25 of the switching drum 3〇 are sequentially discharged to the outside through the exhaust port 25 of the valve body 21; That is, the operating state is that the air pressure W1 is directly switched into the switching space 33 of the switching drum 30. The second of the rotating cylinders is pierced by the air holes 32, and does not pass through the rotating seat 5, and the hollow cavity is provided with the flow opening state of the perforation μ or % or 55. In addition, the operation of the speed control structure mainly causes the rotation of the rotary seat 50 to be synchronously rotated by the rotation of the rotation control knob 61, and the rotation angle of the rotary base 5 turns into a hole 53 with different apertures. And the state of the 55, and the first air venting hole 31 of the switching drum 30 are electrically connected to each other. The difference between the sixth, ninth, and tenth drawings is shown in FIG. 4, wherein the rotating base 5 shown in FIG. 4 is the perforation of the largest aperture. 53 is in a state of being in a position opposite to the first air venting hole 31, and the rotating seat 5G is respectively a hole of the middle hole diameter and the smallest hole diameter, and : and : the air conduction hole 31 is in a relative position conduction state; Therefore, it is possible to adjust the flow rate of the air entering the ventilating hole 31, thereby achieving the purpose of adjusting the operating speed and torque of the rotor of the pneumatic tool. [Advantages of the Invention] Due to the use of the pneumatic tool, the work of the torque speed adjustment is usually only used when the rotor π is in the forward direction (ie, the direction of the rotor), and the workpiece is adjusted by the tightening screw. The difference in the degree of hardness), so the switch in the present invention: the younger brother of the through-hole 31 is specially designed to communicate with the perforation 53 or 53 or 54 of the rotary seat, and the first: wear The air hole 32 is staggered by the rotation seat 50; #这,#Rotor^ When the rotary state is in the forward rotation state, the air bladder is adjusted by the perforation Μ or 53 or Μ (ie, the torque) provided by the rotary seat 5G. The state, in order to meet the demand of the work, and the rotor 11 is in a reverse rotation state of action / the pressure of the person guiding the person is switched from the turn-over space (5) 0 to the flow space 33, then directly enters the switch drum 3 The first air vent 32 is in a fully open state without passing through the rotating seat 5, the hollow cavity, or the hole 53 or 54 or 55, thereby allowing the pneumatic tool to be used, regardless of the torque adjustment state when the rotor 11 is rotated. When: change to the reverse mode, its torque is the maximum state In this way, the speed of the pneumatic tool can be improved by using the (4) screw. In operation, the trouble of frequently adjusting the «circle-speed w control button 6 is eliminated, and the progressive use of more work and efficiency is achieved. . The present invention has been specifically described by the above embodiments, and is made by the terminology of the materials, so as to limit the scope of the invention to 12 12,224,851; The invention can be changed and modified to understand the purpose of the invention. 3 = Amendment should be covered in the scope of patent application as described later. / 13 200824851 [Simplified illustration] 2nd, 3rd, 4th, 5th, 6th, 7th, 9th, 10th, 10th, and is an exploded perspective view of the conventional structure.
