Description of the invention (2) Low, when the hammer set, the incompressible force is caused by the user's hand, and the user's hand is prone to elasticity. Replace the spring. [Summary] The pneumatic tool of the present invention is slow and effective Buffering this size provides a moderate reduction in user benefits. For the body, a slot is provided, and the grip handle is provided with an internal movement, and the connecting rod is provided with one and the middle handle, which should be pressed with a key to hit the hammer, and the connected slot is separated from the rear. The hand of the spring is not tired, but the main purpose of the punching device is to hammer the group. The slow and unusable cylindrical hollow sleeve grip phase pressure switch group, and the group is at the end of the knot rod. The room force is relatively small, and when it is less than the spring elastic force, the spring loses the cushioning effect and causes the back seat to bear. Therefore, the hand feels a large vibration and is easy to take. In addition, the spring reduces the cushioning effect after using it for a period of time. And need to set up and set up the cost of improvement. It is to solve the above problem and provide a method, which uses the compressible principle of air pressure to achieve the effect of recoil, and can greatly reduce the vibration and comfort of the pneumatic tool according to different recoil forces, In order to improve the use of pneumatic tools, the first air chamber and the first communication chamber are connected to the first air chamber. The present invention is a hollow sleeve, the closed end of which is adjacent to the hollow sleeve and the receiving groove can receive a high-pressure air receiving groove. The directional end is connected with a second air chamber, and includes a hollow body, a hollow body is formed in the hollow sleeve, a high-pressure gas canister is provided with a push switch, and an air inlet is provided. The receiving groove is linearly reciprocated. The piston body is driven by an axially arranged piston piston, and the piston penetrates the receiving chamber and one side of the piston through the perforation, and the grip is inserted into the hole.

Description of the invention (4) The plug 3 2 is embedded with an O-ring 3 3 on the outer periphery, and the piston 32 divides the accommodation groove 12 into a first air chamber 3 4 and a first Two air chambers 3 5, and one side of the piston 32 passes through the first air chamber 34 and the second air chamber 35 is provided with a perforation 3 6, the perforation 36 is provided in a cone shape, and the small diameter end is connected Set in the direction of the hammer group 20. A front end cover 40 is fixed at the opening of the accommodation slot 12 of the hollow sleeve 11 and is used for one end of the hammering group 20 to pass through and limits the hammering group 20 to reciprocate The moving stroke is for the piston 32 to move back and forth between the air inlet hole 15 and the inner end surface of the accommodation groove 12; with the structure described above, the buffering device of the pneumatic tool of the present invention is completed. When in use, as shown in FIGS. 2 to 4, the user presses the push switch 1 4 ′ so that the south pressure gas flows into the first air chamber 3 along the push switch 1 4 ′ through the air inlet hole 15. 4, at the same time through the perforation 3 6 of the piston group 30 into the second air chamber 3 5, and the high pressure gas will push out the hammering group 2 0 through the intake of the first air chamber 34, so that The hammering group 20 is pushed out, and the Xin rod 21 is knocked out, and the seating force after the impact will cause the hammering group 20 to retreat toward the piston group 30, and the piston group 30 The piston 32 moves in the direction of the second air chamber 35 to compress the air in the second air chamber 35 by the principle of space compressibility, which effectively has a cushioning effect. Wherein, when the second air chamber 35 absorbs the reverse seat force of the hammering group 20, the air in the second air chamber 35 is compressed, so that the second air chamber 35 is pressurized. A part of the air is guided from the perforation 3 6 to the first air chamber 3 5, and is set into a cone through the perforation 3 6 of the piston group 30.
