Wherein, force is applied to the locking ring 4, so that the locking ring 4 moves along the axial direction of the connecting ring 2 relative to the connecting ring 2 under the sliding guiding action of the guiding piece 5 in the guiding groove 22, and the locking piece 3 is pressed against the optical fiber body or the locking piece 3 is released through the locking ring 4.
In this embodiment, the flange 1 may be connected to a cutting head. Or may be connected to another flange 1 to connect two optical fiber bodies. Laser propagation channels are arranged in the connecting ring 2 and the flange plate 1.
The circumference of the connecting ring 2 is provided with a guide groove 22; the guide piece 5 is arranged on the locking ring 4, and the guide piece 5 is arranged in the guide groove 22 in a sliding way; the locking ring 4 is sleeved on the connecting ring 2. Therefore, when an external force is applied to move the locking ring 4 relative to the connecting ring 2, the guide piece 5 is limited in the guide groove 22, and the guide piece 5 plays a guiding role, so that the locking ring 4 generates displacement along the axial direction of the connecting ring 2 relative to the connecting ring 2, and the locking piece 3 can be conveniently pressed or released by the locking ring 4. In addition, since the guide 5 is limited in the guide groove 22, the coupling ring 2 and the locking ring 4 can be coupled by the guide 5.
The locking member 3 may be a ball, and the ball is pressed against the optical fiber body by the locking ring 4 to connect the optical fiber body in the connecting ring 2; when the locking ring 4 is released from the balls, the fiber body can be pulled away from the connection ring 2.

In one embodiment, the locking ring 4 comprises a locking section and an unlocking section (not shown in the figures), the inner diameter of the locking section is smaller than the inner diameter of the unlocking section, the locking section is used for pressing the locking member 3 against the optical fiber body, and the unlocking section is used for releasing the locking member 3. Because the internal diameter of the locking section is smaller, the locking ring 4 and the connecting ring 2 are relatively moved, so that the locking section of the locking ring 4 moves to the position of the locking piece 3, the locking piece 3 is extruded by the inner wall of the locking section, so that the locking piece 3 moves towards the inner side of the connecting ring 2 in the locking hole 21, the optical fiber body is propped against the connecting ring 2 by the locking piece 3, and the connection between the connecting ring 2 and the optical fiber body is realized. When the unlocking section of the locking ring 4 moves to the position of the locking piece 3, the unlocking section has larger inner diameter, and the locking piece 3 cannot be extruded through the inner diameter of the unlocking section, so that the optical fiber body can be directly pulled out of the connecting ring 2, and the separation of the connecting ring 2 and the optical fiber body is realized.
Optionally, a pressing piece may be further disposed on the locking ring 4, and when the pressing piece moves to the position of the locking piece 3, the pressing piece is pressed, so that the pressing piece moves downwards and is clamped, and the locking piece 3 is pressed, so that the connection between the connection ring 2 and the optical fiber body is achieved. Pressing the pressing piece again can reset the pressing piece, and separation of the optical fiber body and the connecting ring 2 is achieved.
In an embodiment, the joint further comprises an elastic member (not shown in the figure), the elastic member is disposed between the locking ring 4 and the flange 1 or between the locking ring 4 and the connecting ring 2, the elastic member is used for driving the locking ring 4 to move towards a direction away from the flange 1, and the locking section is located at one side of the unlocking section close to the flange 1. Because the elastic piece can drive the locking ring 4 to move towards the direction far away from the flange plate 1, the locking ring 4 can move to the limit position far away from the flange plate 1 under the driving action of the elastic piece and the guiding and limiting action of the guiding piece 5 by the guiding groove 22. And the locking ring 4 is kept at a limit position far away from the flange plate 1 under the elastic action of the elastic piece. In addition, the locking section is located on one side of the unlocking section, which is close to the flange plate 1, so that when the locking ring 4 is located at the limit position away from the flange plate 1, the locking section can just press the locking piece 3, so that the optical fiber body is pressed in the locking ring 4 through the locking piece 3, and the connection between the connecting ring 2 and the optical fiber body is realized. The locking ring 4 is kept at the limit position far away from the flange plate 1, so that the optical fiber body can be always connected with the connecting ring 2. When an external force is applied to the locking ring 4 so that the locking ring 4 moves towards the direction approaching the flange plate 1, the locking section can be separated from the locking piece 3, and the unlocking section is opposite to the locking piece 3; the unlocking section cannot press the locking piece 3, so that the optical fiber body can be easily pulled out from the connecting ring 2, separation of the connecting ring 2 and the optical fiber body is realized, and the efficiency of connecting or separating the optical fiber body from the connector is improved.
In an embodiment, as shown in fig. 1 and 2, the connecting ring 2 is further provided with a limiting groove 23, the limiting groove 23 is communicated with one end of the guiding groove 22, which is close to the flange plate 1, and the extending direction of the limiting groove 23 is along the circumference side of the connecting ring 2. An external force is applied to the locking ring 4 to move the locking ring 4 in a direction approaching the flange 1, and the locking ring 4 moves to a limit position approaching the flange 1 under the guiding and limiting actions of the guiding groove 22 on the guiding piece 5. The unlocking section is just right opposite to the locking piece 3 at this time, so that the unlocking section releases the locking piece 3. When the locking ring 4 moves to the limit position close to the flange plate 1, the locking ring 4 can be rotated, so that the guide member 5 slides into the limit groove 23, and the elastic member cannot drive the locking ring 4 to move towards the direction away from the flange plate 1, so that the state of releasing the locking member 3 can be maintained.
In one embodiment, as shown in fig. 1 and 2, the guide groove 22 extends in a direction parallel to the axial direction of the coupling ring 2 so that more force acts on the axial direction of the coupling ring 2, reducing the force applied to the locking ring 4 to move the locking ring 4 relative to the coupling ring 2, thereby allowing the locking ring 4 to be rapidly moved to the locking position or the releasing position.
In one embodiment, the connecting ring 2 is integrally arranged with the flange plate 1, so as to reduce pollution and simplify the structure.

The cooling liquid is introduced into the liquid inlet 11, so that the cooling liquid flows through the cooling channel, and flows out of the liquid outlet 12 after taking heat away, thereby improving the heat dissipation efficiency.
In an embodiment, as shown in fig. 1 and 2, a temperature sensing component 6 is disposed in the connection ring 2, the temperature sensing component 6 is used for being connected with the optical fiber body, and the temperature sensing component 6 is disposed on one side of the locking hole 21 near the flange plate 1.

The temperature sensing component 6 is arranged on one side of the locking hole 21, which is close to the flange plate 1, so that the temperature sensing component 6 can be prevented from interfering the connection of the optical fiber body and the connecting ring 2.
In one embodiment, as shown in fig. 3 and 4, the temperature sensing assembly 6 includes a temperature sensor 61, a contact ring 62 and a contact 63, the connection ring 2 is provided with a receiving groove 24, and the temperature sensor 61 is disposed in the receiving groove 24; the contact ring 62 is covered on the accommodating groove 24, the contact ring 62 is electrically connected with the temperature sensor 61, and the contact ring 62 is arranged on one side of the locking hole 21, which is close to the flange plate 1; the contact 63 is disposed on a side of the contact ring 62 facing away from the accommodating groove 24, and the contact 63 is electrically connected with the temperature sensor 61. Wherein both the contact ring 62 and the contact 63 are adapted to be connected to the fiber body.
The temperature sensor 61 is arranged in the accommodating groove 24 in the connecting ring 2, so that the space for installing the temperature sensor 61 and the contact ring 62 can be reduced; the suspended area of the contact ring 62 can be reduced, and the mounting stability of the contact ring 62 can be improved. The contact ring 62 and the contact 63 are both connected to the temperature sensor 61 and also to the fiber body so that the laser can be turned off.
The temperature sensor 61 may be a temperature switch to directly turn off the laser light through the temperature sensor 61. A temperature sensor is also possible to transmit a temperature signal to switch off the laser via a further switch.
