[0022] The utility model is further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, the surfaces of the two jaws 2 of the pliers body 1 are respectively provided with a trapezoidal slide 3, the trapezoidal slide 3 is connected with a clamping member 5 through a fastener 4, the lower end of the clamping member 5 is provided with a trapezoidal block 6 that matches the structure of the trapezoidal slide 3, the two clamping members 5 are arranged opposite to each other, the top surface of the clamping member 5 is provided with an air pipe groove 7, and the inner surface of the clamping member 5 is provided with an avoidance opening 8.

[0024] The surface of the clamping member 5 outside the trachea groove 7 and the avoidance opening 8 is provided with a rubber strip 12 to enhance the friction force.

[0025] The fastener 4 is a bolt, which is convenient for disassembly and locking. The lower end of the jaw 2 is provided with a waist-shaped hole that matches the structure of the fastener 4. When used specifically, the position of the clamp 5 can be adjusted according to the size of the air pipe and joint 11 to be operated. Through the sliding connection between the trapezoidal slide 3 and the trapezoidal block 6, the clamp 5 is slid to a suitable position, and then the position of the clamp 5 is fixed by the fastener 4. When the position or direction of the clamp 5 needs to be changed, the fastener 4 is removed and the position of the clamp 5 is re-determined.

[0026] The trachea grooves 7 at the upper ends of the two clamping members 5 are set to the same or different sizes. In specific use, the two trachea grooves 7 are set to the same or different sizes according to the actual situation and the model and outer diameter of the trachea. When the trachea grooves 7 at the upper ends of the two clamping members 5 are processed into different widths, they are respectively suitable for trachea 9 and joints 11 of different sizes.

[0027] The width of the tracheal groove 7 is 2 mm greater than the outer diameter of the trachea 9. When the outer diameter of the trachea is 3, 4, 6, 8, 10, 12 mm, the width of the tracheal groove 7 is 6, 8, 10, 12, 14 mm, respectively.

[0028] The width of the tracheal groove 7 is larger than the outer diameter of the trachea 9 and smaller than the outer diameter of the button cover 10 .

[0029] The shape of the clamping member 5 is L-shaped, and the avoidance opening 8 is located at a side away from the L-shaped bending part.

[0030] When used specifically, Figure 6 As shown, the trachea groove 7 carries the trachea 9, and the inner side of the trachea 9 is connected to the joint 11 through the button sleeve 10. The two jaws 2 of the clamp body 1 are clamped together, and the clamping member 5 presses the button sleeve 10 to loosen the retaining spring at the connection between the trachea 9 and the joint 11, thereby completing the disassembly operation and removing the trachea 9.

[0031] When used specifically, the joint 11 is one of a straight joint, an L-shaped joint, and a tee joint. When the joint is an L-shaped joint or a tee joint, the clamping member 5 can be reversed as needed to clamp and fix the joint 11, such as Figure 7 As shown, at this time, the avoidance opening 8 plays the role of avoiding the air pipe.

[0032] The utility model designs the jaws to be laterally embedded with a trapezoidal slide, and the clamping piece 5 is fixed to the jaws by the trapezoidal slide and the fasteners. The fixing position of the clamping piece 5 can be adjusted according to the size of the quick connector, and the clamping piece can be replaced according to the outer diameter of the trachea so that the clamping piece clamps the trachea. The clamping of the pliers can press the retaining spring at the connection between the trachea and the connector.
