If the specific posture changes, the directional indication will also change accordingly.

[0020] like Figure 1-Figure 7 As shown, a connection socket comprises: Operation shell 100; A connecting shell 200, the connecting shell 200 is located inside the operating shell 100, the operating shell 100 can move linearly along the axis direction of the connecting shell 200, a connecting through cavity 201 is provided inside the connecting shell 200, and a gap is provided between the operating shell 100 and the connecting shell 200 to form the installation cavity 101; At least two claw parts 300 are arranged in the installation cavity 101, each claw part 300 includes a claw 301, and the plurality of claw parts 300 are arranged around the side of the connection shell 200, and the claw parts 300 can rotate relative to the connection shell 200, and the claws 301 are provided with an execution part, and the operation shell 100 is provided with an operation part 105; In the first working state, the claws 301 on the claw portion 300 are all extended into the connecting cavity 201, and there is no power transmission between the execution portion and the operating portion 105; In the second working state, the execution part is connected to the operation part 105 , and the claw 301 on the claw part 300 is retracted into the installation cavity 101 .

[0021] In this embodiment, the claw portion 300 and the connecting shell 200 are rotationally connected, so that the movement mode of the claw 301 is changed from the existing translational mode to the rotational mode in this application, and the working stroke of the claw 301 in the installation cavity 101 is shorter, thereby reducing the space thickness required for the installation cavity 101. Then, when the operating shell 100 remains unchanged and the shell wall thickness of the connecting shell 200 remains unchanged, the cross-sectional size of the connecting cavity 201 in the connecting shell 200 is larger, thereby realizing connection with the connecting joint 500 with a larger cross-sectional size.

[0022] Preferably, the claw portion 300 also includes a tilting rod 302 arranged in the installation cavity 101, the first end of the tilting rod 302 is fixed to the claw 301, the execution part is arranged at the second end of the tilting rod 302, and a tilting portion 303 is arranged on the tilting rod 302, and the tilting rod 302 can rotate around the tilting portion 303.

[0024] In this embodiment, in the first working state, the tilting rod 302 is connected to the outer shell wall of the connecting shell 200 by abutment, and the executing rod 304 is tilted and does not contact the connecting shell 200, and a gap is left between the executing rod 304 and the connecting shell 200 to reserve a rotation space for the executing rod 304, and a tilting portion 303 is formed at the connection between the executing rod 304 and the tilting rod 302. As the operating shell 100 moves relative to the connecting shell 200 (the tilting rod 302 is toward the direction of the executing rod 304), the operating part 105 on the operating shell 100 gradually approaches the executing rod 304 and abuts against the executing rod 304. As the operating shell 100 continues to move, the operating part 105 squeezes the executing rod 304 to rotate around the tilting portion 303, and the claw 301 retracts into the installation cavity 101, thereby disconnecting the connection with the connecting joint 500.

[0025] It is worth mentioning that the operating portion 105 includes an operating block fixedly disposed on the inner shell wall of the operating shell 100 .

The number of the installation grooves 204 is equal to the number of the claw parts 300. The installation groove 204 passes through the limiting groove 202, dividing the limiting groove 202 into multiple independent sections, and the tilting rod 302 is installed in the installation groove 204. At the same time, the elastic ring 203 in the limiting groove 202 is also sleeved on the tilting rod 302, so that the tilting rod 302 will not separate from the installation groove 204 after being tilted.

[0028] Specifically, a groove 305 is provided on the tilting rod 302 , and the elastic ring member 203 is sleeved in the groove 305 to achieve connection with the tilting rod 302 .

[0029] It is worth mentioning that the elastic ring member 203 can be selected from one of an elastic rubber ring, a retractable rope, or a tension spring connected end to end to form a ring.

[0030] Further preferably, the connecting shell 200 is provided with engaging notches 205 , the number of the engaging notches 205 is equal to the number of the engaging claws 301 , and the engaging claws 301 on the engaging claw portion 300 pass through the engaging notches 205 .

In the first working state, the engaging claw 301 passes through the engaging notch 205 and extends into the connecting shell 200, while in the second working state, the engaging claw 301 retracts into the mounting cavity 101. At the same time, the setting of the engaging notch 205 enables the engaging notch 205 to limit the engaging claw 301 in the first working state, thereby preventing the engaging claw 301 from moving along the axial direction of the connecting shell 200.

[0032] Further preferably, a limiting portion is provided on the connecting shell 200, and an abutting portion is provided on the operating shell 100, wherein in the second working state, the limiting portion is abutted and connected with the abutting portion.

[0036] Further preferably, a first elastic member 104 is provided in the activity space, and the two ends of the first elastic member 104 are respectively connected to the end of the limit ring 103 and the tail interface 401. The setting of the first elastic member 104 enables the operating shell 100 to move relative to the connecting shell 200. After switching from the first working state to the second working state, the operating shell 100 is released. Under the elastic force of the first elastic member 104, the operating shell 100 can be automatically reset, and the connecting socket also switches back to the first working state.

[0038] In this embodiment, the second elastic member 404 is provided so that the valve ring 403 has a certain elastic range of motion, and can adapt to connecting joints 500 of different lengths, so that the connection socket in this application has a wider application range.

[0039] like Figure 8 As shown, a fluid connector includes the connection socket as described above, and also includes a connection joint 500. When the connection joint 500 is inserted into the connection shell 200, the claw 301 is clamped in the clamping groove on the connection joint 500.

[0040] It is worth mentioning that a locking column is provided on the connecting joint 500, and a locking groove is provided on the connecting shell 200. When the connecting joint 500 is inserted into the connecting shell 200, the locking column is inserted into the locking groove to prevent the connecting joint 500 and the connecting shell 200 from rotating relative to each other.
