Description of the invention: [Technical field to which the invention pertains] • Transit is related to a type of connector, particularly a type of quick connector. [Prior Art] Referring to the structural design of the Figure-like quick connector 1, the utility model mainly comprises: a joint body u for connecting two pipe members (not shown), a set of spring claws 12' disposed outside the joint body 11 and - The sleeve 13 is placed outside the joint body 丨1 and the magazine #12. The elastic claw 1 has a set of annular positioning ring portions 121 positioned on the joint body U, three claw portions 122 ′ symmetrically disposed on the positioning ring portion i2i, and three symmetrically disposed between the adjacent claw portions 122. The inverted v-shaped bullet top 123. When the quick connector 1 is used, the claw portion 122 of the claw 12 is driven radially outward by the axial displacement of the outer sleeve 13 relative to the joint body u to the release position, so that the tubular member can be inserted. Mounted in the joint body U 'or the tube can be pulled away' and the outer top 13 of the spring 3 1 claw 12 is elastically pressed by the outer sleeve 13 so that the tops of the bullets (2) respectively accumulate a reset elastic force' - However, the force of the outer sleeve 13 is lost, and the outer sleeve 13 is reset by the top. However, the elastic claws of the inverted v-shaped top 123 are quite inconvenient. The condition of adjusting the elastic parameters of the elastic force of the elastic material 123 is not easy, so it is not easy to change the size structure of the top 123 of the elastics. Push the elastic force. In addition, when the outer sleeve 13 is displaced to the loose position, the two ends of the z-shaped portion (four) portion 123 are deformed by the outer sleeve η and the joint body u (4), and the stress is easily generated at the turning points of the two ends. Concentration causes damage or breakage at the turning point of the top of the projectile, which is more likely to cause elastic fatigue. SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a quick connector that is easy to manufacture and use.

At the same time, the urging ribs 531 of the urging units 53 are respectively moved down along the abutting slopes 43 of the corresponding reset spring arms 43 to force the pair of returning spring arms 43 to gradually approach the elastic yaw. The pair of reset spring arms 43 accumulate the reset spring force of the pendulum reset, and at this time, the outer sleeve 5 has been moved downward relative to the spring claws 4 to the release position. * After the s pieces have been removed or have been inserted, the outer sleeve 5 can be released. When the pair of reset spring arms 43 are opposite to each other, the elastic back swing will be reset, forcing the I and other ribs 53 to gradually follow. The slanting surface 43() is moved up, and the pipe body 51 drives the ejector block 52 to move up and down to the buckle position, so that the pusher 52 is forced to abut the claws 42. The outer side of the block segment forces the card segments 422 to penetrate again into the communication conduit 30 and can be snapped onto the tubular member. The resetting elastic arm portion 43 passing through the spring claws 4 has a structural design for the inclined abutting inclined surface 43〇 against which the pushing ribs 7 1380532 531 abut, so that the elastic arms can be elastically The outer sleeve 5 is moved by the elastic force of the resetting, and the reset spring arm portion has a long rod shape, and the structure is relatively simple, and the outer diameter of the reset spring arm portion 43 can be adjusted by changing the cookware structure during manufacture. , the purpose of adjusting the elasticity of the reset spring arms 43 is achieved. Referring to Figure 6, the second preferred embodiment of the quick coupler of the present invention differs only in the design of the relative thrust between the pair of reset spring arms. For convenience of explanation, the differences between the following embodiments and the first embodiment will be described. In the present embodiment, the thrust ramps of each of the two pairs of reset spring arms 43 are spaced apart toward each other and are gradually extended away from the positioning loops. The abutting ribs 531 of the thrust pushing units 53 are opposed to the opposite opposing inclined faces 430 of the pair of resetting elastic arm portions 43, respectively. When the outer sleeve 5 is displaced downward to the loose position, the abutting (four) 531 forces the pair of reset spring arms 43 to be elastically biased outwardly, and the reset elastic force is accumulated so that the reset spring arms 43 can be After the loose tube casing 5 is manufactured, the outer sleeve $ is pushed up to the buckle position. In the present embodiment, each of the anti-pushing units 53 has two anti-pushing ribs 53ι, but in practice, only a single anti-pushing rib 531 may be provided, and the anti-pushing ribs 531 are simultaneously lowered to the pair to be reset in pairs. The slanting of the spring arm portion 43 can also achieve the purpose of forcing the resilient spring arms 43 to be elastically yawed. In summary, the vertical rod-like structure design of the spring-loaded arm portion 43 is such that when the spring A 4 is manufactured, the structure of the mold is set to be simpler, and the branch is simply modified by the mold structure. The size of the rod is corresponding to the modification of the outer diameter of the rod-shaped reset elastic arm portion 43, so that it is convenient to adjust the manufactured spring according to the requirement of (10); the elastic arm portion 43 of the K 4 is elastically enabled to make the quick joint It is more convenient to manufacture and is more convenient and practical. In addition, by designing the structural design of the reset spring arm portion 43 in a straight rod shape, it is possible to overcome the problem that the turning point of the top of the inverted V-shaped projectile is easy to stress concentration and easily cause elastic fatigue, so it can be relatively increased. The service life of the quick connector. Therefore, the object of the present invention can be achieved. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent change and modification according to the scope of the patent and the description of the invention in the present invention. All remain within the scope of the invention patent.
