[0022] Specifically, the control component 4 includes a support 41, a screw 42, a movable plate 43, a connecting rod 44, a rotating shaft 45, a bevel gear 1 46 and a bevel gear 2 47. The support 41 is arranged on the side of the connecting seat 3, two screws 42 are embedded in the support 41, and the top of the screw 42 is connected to the bevel gear 2 47, the side of the fixed arc plate 7 is connected to the connecting rod 44, and the side end of the connecting rod 44 is connected to the movable plate 43, and the top of the support 41 is embedded with a rotating shaft 45, and the surface of the rotating shaft 45 is sleeved with two bevel gears 1 46, and the sides of the bevel gear 1 46 and the bevel gear 2 47 are meshed with each other, and the thread directions of the surfaces at both ends of the screw 42 are opposite.

[0023] By adopting the above technical solution, the rotating shaft 45 drives the two bevel gears 1 46 to rotate. Under the meshing transmission between the bevel gear 1 46 and the bevel gear 2 47, the two screws 42 can rotate synchronously. Under the meshing connection between the screw 42 and the movable plate 43, since the thread directions of the two end surfaces of the screw 42 are opposite, the two movable plates 43 can respectively drive the fixed arc plate 7 to move toward each other through the connecting rod 44. The connecting seat 3 can complete the air pipe connection and fixation through the fixed arc plate 7 and the fixed groove 6 on the surface of the pneumatic valve connector 5. The operation is simple and convenient, and the use effect is better.

[0024] Specifically, the surface of the screw rod 42 inside the support 41 and the surface of the rotating shaft 45 are both sleeved with positioning blocks 48, and the positioning blocks 48 are in a circular ring structure.

[0025] By adopting the above technical solution, the positioning block 48 plays a limiting role, which can make the meshing transmission between the bevel gear 1 46 and the bevel gear 2 47 more stable and firm, and the transmission control effect is better.

Under the meshing transmission between the bevel gear 1 46 and the bevel gear 2 47, the positioning block 48 plays a limiting role. The two screws 42 can rotate synchronously, and under the meshing connection between the screw 42 and the movable plate 43, because the thread directions of the surfaces at both ends of the screw 42 are opposite, the two movable plates 43 can respectively drive the fixed arc plate 7 to move toward each other through the connecting rod 44, and the connecting seat 3 can complete the air pipe connection and fixation through the fixed arc plate 7 and the fixed groove 6 on the surface of the pneumatic valve joint 5.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that the protective assembly 8 includes a protective cover 81, a mounting block 82 and a mounting groove 83, two mounting grooves 83 are provided on the side of the welding machine body 1, the mounting blocks 82 are embedded in the mounting grooves 83, and the side of the mounting block 82 is connected to the protective cover 81.

[0031] Specifically, the mounting block 82 and the mounting groove 83 are both T-shaped structures, and the protective cover 81 and the welding machine body 1 are split structures.

[0032] By adopting the above technical solution, the protective cover 81 is slid into the mounting groove 83 through the mounting block 82. The T-shaped mounting groove 83 limits the mounting block 82 so that the protective cover 81 can be positioned above the trachea connection, which can provide better protection for the trachea connection.

[0033] When this embodiment is used, the protective cover 81 is slid into the mounting groove 83 through the mounting block 82. The T-shaped mounting groove 83 limits the mounting block 82 so that the protective cover 81 can be positioned above the trachea connection, thereby providing better protection for the trachea connection.

Its working principle is that the surface of the mounting seat 2 on the side of the welding machine body 1 is sleeved with the connecting seat 3, and the fixing arc plate 7 connected by a screw rod inside the connecting seat 3 is clamped with the fixing groove 6 on the surface of the pneumatic valve joint 5 to complete the air pipe connection and fixation.

[0035] The working principle and use process of the utility model: when the utility model is used, the surface of the mounting seat 2 on the side of the welding machine body 1 is sleeved with a connecting seat 3, and the rotating shaft 45 drives the two bevel gears 1 46 to rotate. Under the meshing transmission between the bevel gear 1 46 and the bevel gear 2 47, the positioning block 48 plays a limiting role. The two screws 42 can rotate synchronously, and under the meshing connection between the screw 42 and the movable plate 43, because the thread directions of the surfaces at both ends of the screw 42 are opposite, the two movable plates 43 can respectively drive the fixed arc plate 7 to move toward each other through the connecting rod 44, and the connecting seat 3 can complete the connection and fixation of the air pipe through the fixed arc plate 7 and the fixed groove 6 on the surface of the pneumatic valve joint 5. The operation is simple and convenient, and the use effect is better. The protective cover 81 is slid into the mounting groove 83 through the mounting block 82. The T-shaped mounting groove 83 limits the mounting block 82 so that the protective cover 81 can be positioned above the air pipe connection, which can better protect the air pipe connection.
