In addition, the increase in the discussion of the err, so that the view L M303087 has inappropriately reduced the county, the shadow of Wei Wei, the driver of the horse, the financial strength, self-scale and low efficiency. The above-mentioned known patents are not perfect, and they think about how to avoid the problem of the negative effects caused by Cui Chun's increased torque. This case is based on the design, production and production of money scales. The accumulated experience' is further conceived and actively researched and improved. After a long period of trials, we finally developed and designed a more sophisticated and practical creation. Efforts [new content] The main purpose of this creation is to provide a double-piston type motion mechanism for pneumatic tools, which is especially a kind of profit-making red-skinned _, the same thing for the double-piston position, and the air motor flow The direction, and then quickly change the riding direction, so that the increase in horsepower. s 鉴 鉴 鉴 'The design of the movement mechanism dedicated to pneumatic tools includes: - the outer cylinder, hollow and - end - with the neck of the σ inner cylinder, The internal thread of the short shaft is formed with the other end forming a joint with an outer cymbal, and the _ cylinder comprises a first perforation, a second perforation and a third perforation arranged in a radial direction, wherein the first perforation is Providing a face-to-face switching air chamber to elastically pass the clamping position. The remaining second and third perforating systems are respectively connected to each other and respectively have a piston rod embedded therein, and the first perforated inner wall has at least one or more guide ends at both ends thereof. The second and third perforations and joints are in place. Correspondingly, there are more than one second air guiding hole and one air inlet hole; and two first air discharging holes are provided in the axial direction downward, and corresponding two second air discharging holes are provided, respectively, respectively The middle portion of the third perforation penetrates the inner cylinder vertically upwards; thereby, in operation, by switching the switching of the switching, the simultaneous movement of the tongue base toward the |5] direction enables the gas to enter the motor group more quickly. Internally, changing the direction of the motor tube flow, the Asian servant can control the positive and reverse directions of the motor in real time, so that the natural benefits of improving the pneumatic defensive force can be achieved. In order to enable your members to further understand the structural features and functions of this creation, the following is a detailed description of the M303087 best implementation of the shooting coordination diagram as follows: [Embodiment] See the -, - map, The present invention is a "double-piston type motion mechanism for pneumatic tools".

Sealed by a cap (6 5 4), an elongated circular groove (6 5 5 ) is arranged in the middle of the circumferential surface of the pressing switching valve (65) for the insertion of a fixed needle (6 8) And a groove (6 5 6 ) is arranged on both sides of the groove (6 5 5 ), and an oil seal (6 5 7 ) is added to the side of the small round hole (6 5 6 ), thereby The press switching air valve (65) is positioned in the first through hole (6 2 3 ), and reciprocates by pressing the pressing disk (6 51) and the elastic body (6 5 3 ) to switch the small round hole (6 5 6 ), and then reach the positive and negative direction of the control motor. According to the above-mentioned double-piston type motion mechanism (60), when installed in the pneumatic tool (1) and actually operated, the positive and negative actions of the motor group are as follows: as shown in the third and fifth figures, when the user When the pressing switching valve (6 5) is kept stationary, the high-pressure gas enters the short shaft (6 21) of the inner cylinder (62) by the joint (6 4), and one of the switching valves (65) is pressed by pressing. After keeping the small round hole (6 5 6 ) opened, the first air hole Γ fi ? q 1 左 on the left side of the third figure enters the second and third perforations (6 2 4, 6 2 5 ) and pushes the two pistons Column (moving in June ~ direction (ie moving to the right of the third figure), while closing and closing the other end (the right side of the third figure) is set at the second, third place - the perforation (6 2 4, 6 2 5 The second air guiding hole (6 2 41) and the air inlet hole (6 2 R ί, 丄) of the inner wall, at this time, the high pressure air continues to be opened by the second air guiding hole (6 2 4 i) and the air inlet hole (Θ 2 5 Ί〉* ^ The 彡 is injected into the motor group (5 〇), and drives and causes the rotor to rotate forward, while the seven: wide [empty will be after the rotor rotates in relation to the intake of the other - the first - Vent hole (6 7) The discharge is carried out, and the rest is discharged through the second intake hole (6 M303087 8) through the other intake hole (625 1). Similarly, as shown in the fourth and sixth figures, when used The user controls the pressing switching valve (W) to move inward: the secret air is in the short axis (6 2 i) after entering the joint (6 4), and is switched by the pressing switching valve (6 5). After the closed-to-open small round hole (6 5 6 ) is entered, the corresponding first-air vent (6 2 3丄) enters the right side of the fourth figure, and passes through the second and third perforated ad 6(5) Zheng. Move the two piston rods (6 6 ) _ the other side of the heart - the direction of movement (ie move to the left of the fourth picture) 'will also close the other end of the original open (the left side of the fourth picture) is set in the second and third The second air guiding hole (6 2 4 1 ) and the air inlet hole (6 2 5丄) of the inner wall of the perforation (6 24, 6 2 5 ), at this time, the high pressure air _ (four) paste (four): the loss (6 2 4 i ) money The vent (6 2 51) in the 4-person motor group (5 Q) 'drives and causes the rotor to reverse, * part of the high-pressure air will rotate after the rotor rotates with respect to the first venting hole (6 7) Do the first discharge, the rest The second exhaust will be made by the second exhaust hole (6 8 ) through the other air intake hole (6 2 5 !): As can be seen from the above description, this creation is especially for the control of the pneumatic tool.
