Description

1228172 V. Description of the invention (1)] A fluid using a fluid as an instrument [Technical field to which the invention belongs] The present invention relates to a guide device. [First-aid technology] The structure of the second phase of quality is called crescent moon *, and the quality of life that people need is equal to ^, and the requirements of things are from the old thinking of "useable": it is quite delicate Only the concept of continuous progress or innovation can meet the needs of modern society. "The appendix shown in the product is a new patent case of China Patent Bulletin No. 51〇467 with quick connector". From the perspective of the previous case, it is known that the guiding device for fluid instruments using air rolling as power is 2 which is inserted into the body 1 by the plug body 60 for application to power machinery. The body and body are mainly composed of an inner side. A retaining unit 10 containing a plurality of balls 15, a set of movable pipes on the outer edge of the aforesaid resisting unit 1G, and a first fixed pipe 21 and a plurality of input holes 221 arranged in the resisting unit 10 The second fixing tube is provided with a receiving groove 211 for the second leak-proof ring body 25 sets in the first fixing tube 21, and an opening body 30 is sleeved on the second fixing tube 22 to form a Fluid guiding device. s μ The above-mentioned conventional guiding device has the effect of preventing leakage of airtightness, and a leak-proof ring body 25 made of a soft material is provided inside the first fixed tube 21, and the cross-section of the leak-ring body 25 is-, L " shape, and make the plug-in "Ministry 62" must be commensurate with the leak-proof ring body 25, so that the cross section is also "L" (Figure 3-2 in the annex), and this structure design , The system will not be effective

$, The effect of the secret, it is known that the internal structure of the connecting pipe 50 called in the conventional structure = the air pressure is quite large, which will compress the second fixed pipe 22 to the 21st to the 21st direction, but the first The fixing tube 21 can also compete with the air pressure by the elasticity of the elastic body 27, so that the actuating unit 20 will maintain a car to return to the force. Although its displacement is not large, it will still make the L-shaped second The leak-proof ring body 25 is separated from the fitting relationship with the plug portion 62, and thus the image body can be separated by two

The resulting "L" -shaped voids leak out, and as a result, the effectiveness of the pneumatic tool is reduced. A In view of the lack of structure of the conventional invention, the inventor has invented a "fluid guiding device for a fluid-powered device", which can swallow all the shortcomings of the conventional products. [Summary of the Invention] The technical problem to be solved by the present invention "a fluid guiding device using a fluid as a power device" is that the conventional fluid guiding device has an actuating unit which is subject to the opposing forces of air pressure and an elastomer. When the reciprocating movement occurs, the insertion part of the connector body will be separated from the close relationship with the leak-proof ring body, and the gas inside the actuating unit will be continuously leaked from the gap, thereby affecting the fluid instrument using the guiding device. Efficiency. The fluid guiding device of the present invention using a body as a power instrument "includes: an abutting tube having a first end and a second end, the ^ end is provided with a positioning steel ball; a round pipe is inserted, and one end is The input end and the other end are combined with the first end of the abutment tube; a control tube is set in the input tube and has a closed end and an open end, and the closed end is sleeved with a movable piece to connect with the wheel.
