The joint is actuated by a combination with the actuating lever (81)#(81) It is combined with the one-way reading door; I:: the rotation and filling... Although the joint can be released after the check valve, the gas is released to avoid the leakage of gas, but; Rotate the rotary knob a few times (...after making (4) (81): Second, the way of this rotation is easy to rotate the rotating button (8 2) too much, and the damage is caused early. This is quite inconvenient and time-consuming to operate. The combination of the existing joint (7 〇) (8 〇) and the check valve of the M287901 has its limitations and inconveniences for the user. [New content] Therefore The creator is not satisfied with the lack of use of the existing joints. After continuous research and experimentation, the author finally developed a novel that can improve the existing defects. The main purpose of this creation is to provide an improved fast. The joint knot 2 should be made by the elastic action mode to avoid the quick joint to the check valve t. When the quick joint is operated, the joint can be made more quickly and without the need of 5 multiple rotations. To the above, the purpose is to provide a quick connector, which is provided with an interface at one end of the body, and the body 2 is abutting the block, and the body is The inner portion is provided with a phase hole of the interface, and the outer circumference of the body is connected with a through-chamber that communicates with the chamber through the abutting block, and is disposed on the outer circumference of the body. a conveying head that conveys a gas and is coupled with the one; and two: the sleeve is movably disposed on the inner edge surface of the two elastic=ends of the chamber of the body; The M y / H parts are respectively disposed on the _ dance element and the second elastic element of the chamber i of the main body, and the first-time-end-end loyalty is loyal, and the sin of the scorpion elastic 兀1 abuts The other end is provided with the inner edge surface of the hole provided with the 6 M287901 hole; the end is inserted through the through hole of the body, and the end of the abutting ring system and the second end of the second bullet are close to the actuation. Between the abutting ring of the chamber, a set of actuating rods respectively in the first loop and the second through hole are formed in the groove formed by the ring; - an actuating rod, wherein the actuating rod - an abutment ring is attached to the actuating shaft extending from the other end of the actuating lever, the component: the end phase abuts and the second elastic element: the end phase abuts, and the actuating rod is disposed between the rings The f-hai actuating rod is further provided with two washers, wherein the first washer is housed in the body and the second washer is sleeved on the abutment ring. And the sleeve and the button of the button of the button are: the face is opposite to the body; and the operation button is combined with the end of the actuating rod extending through the body through the opening of the body. With the above-mentioned technical hand [this creation can make the quick joint can be quickly opened and closed by the operation of the button, the actuating rod, the casing and the two elastic members by the elastic and the abutting operation. The effect of the valve and the elastic force of the two elastic elements enable the quick joint to have a buffering effect with the early valves of various specifications, thereby effectively increasing the range of use of the joint, thereby forming a rapid operation, wide use and reducing pollution.
