In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0087] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0088] like Figure 1 As shown, in the related art, pipe joints generally adopt a cylindrical structure. This shape is easy to cause rotation and slipping when assembled into the equipment. In addition, the pipe connection direction of the pipe joint is not easy to fix due to the need to clamp the pipe, which can easily cause the pipe joint to move forward and backward, resulting in an unstable fixation of the pipe joint; or because the pipe connection direction is fixed, the pipe is not easy to install or remove, causing inconvenience to the user. The fixing structure 20 of some pipe joints occupies additional space inside the equipment, resulting in a non-compact structure. In view of this, the present invention is proposed.

[0089] Combine the following Figures 2 to 12 , describing an embodiment of the present invention.

[0093] A fixing structure 20 is arranged on the joint body 10 to detachably fix the joint body 10 at a preset position, so as to prevent the joint body 10 from moving and slipping, and to facilitate the fixing of the joint body 10 with high fixing reliability. Since the extension plane of the fixing structure 20 is parallel to the axis of the joint body 10, or the axis is located in the extension plane, the fixing structure 20 will not occupy additional space in the vertical direction after installation, and the spatial layout is more compact, which is also conducive to the miniaturized design of the equipment.

Preferably, the two fixing ears are symmetrically arranged on the outer peripheral side of the joint body 10, and the extension planes of the two fixing ears overlap each other. It should be noted that the surrounding edge 22 is also symmetrically arranged with the fixing body 21 as the symmetry plane. In this way, it is not necessary to judge the upper and lower positions of the joint assembly during installation. Figure 2 The state shown can be installed normally even after being turned upside down, thereby improving the installation efficiency.

The plurality of locking teeth are arranged at intervals, which has a certain buffer deformation space, can also save materials and reduce weight.

[0113] The inner wall of the sleeve of the first clamping member 31 forms an oblique groove which gradually expands from the inside to the outside, so as to facilitate cooperation with the second clamping member 32, and the oblique groove structure is used to limit the second clamping member 32 to prevent it from escaping from the first clamping member 31; the first clamping portion 311 of the first clamping member 31 is clamped with the second clamping portion of the connector body 10 to form a connection between the clamping assembly and the connector body 10, which has a simple structure and is easy to assemble.
