Preferably, the protruding shaft 201b, the inserting groove 201f and the transition groove hole 201g are cylindrical grooves and coaxial with each other. It should be noted that the spherical center of the spherical groove 201e is located on the axis of the protruding shaft 201 b.

The relay box 201 is provided with a switching piece 204, the switching piece 204 comprises a round ball 204a and a round tube 204b, and the round ball 204a is arranged at the end of the round tube 204 b; the ball 204a is disposed in the ball slot 201e, and the circular tube 204b is disposed in the insertion slot 201f through the end of the transition slot 201 g.

The spherical ball 204a is provided with a radial groove 204a-1, the circular tube 204b is provided with an axial groove 204b-1, and the radial groove 204a-1 and the axial groove 204b-1 are vertically arranged and communicated.

It should be noted that, the center of the spherical ball 204a is located on the axis of the circular tube 204b, the switching member 204 can rotate around the axis of the circular tube 204b in the tubular shaft 201c, and during the rotation, if the through hole 201j coincides with the radial groove 204a-1, the cavity 201d is communicated with the insertion groove 201f, and if the through hole 201j does not coincide with the radial groove 204a-1 completely, the cavity 201d is not communicated with the insertion groove 201 f.

Further, one end of the air passage pipe 202 is provided with a through groove 202a along the axial direction, and the air passage pipe 202 is provided with an air hole 202b along the radial direction, and the air hole 202b is communicated with the through groove 202 a.

A spiral strip 202c is arranged at the opening of the through groove 202a, and a spiral groove 204b-2 is arranged on the outer side of the end part of the circular tube 204 b; the end of the air passage pipe 202 is provided with an insert 202d, the insertion groove 201f is provided with a guide groove 201h along the radial direction, and the insert 202d is embedded in the guide groove 201 h.

It should be noted that the insert 202d is disposed at one open end of the through slot 202 a.

The sealing piece 203 comprises a sealing ring 203a and a nut 203b, the outer side of the protruding shaft 201b is provided with an external thread, and the sealing ring 203a is arranged at the end part of the protruding shaft 201 b;

the nut 203b is sleeved on the air passage pipe 202 and is screwed with the protruding shaft 201 b.

The gas circuit pipe 202 is detachably connected with the relay box 201, specifically, the assembling process is to insert the insert 202d into the guide groove 201h correspondingly, the end of the gas circuit pipe 202 contacts with the end of the circular pipe 204b in the inserting process, the insertion is stopped, the sealing ring 203a and the nut 203b are sequentially sleeved on the gas circuit pipe 202 and are connected with the external thread on the convex shaft 201b in a screwing mode.

The insert 202d is sealed in the guide groove 201h by the seal ring 203a, so that the air passage pipe 202 can move only linearly along the guide groove 201h and cannot rotate.

In this process, preferably, the distance from the end of the circular tube 204b to the end of the protruding shaft 201b is the same as the thickness of the insert 202d, so that when the end of the circular tube 204b contacts the end of the gas path tube 202, one side of the insert 202d contacts the seal ring 203a, thereby preventing the gas path tube 202 from shaking.

It should be noted that, at this time, the end of the spiral bar 202c corresponds to the end of the spiral groove 204b-2, and further, the insertion groove 201f is further provided with a spring and a circular tube 204b, and the spring is connected along the radial direction of the circular tube 204b, so that the circular tube 204b cannot rotate randomly, and it is ensured that the end of the spiral groove 204b-2 on the circular tube 204b in the initial state corresponds to the end of the spiral bar 202 c; the spring is torsionally stretched as the tube 204b rotates.

It should be noted that, in this initial state, the through hole 201j is completely misaligned with the radial groove 204a-1, that is, the cavity 201d is not communicated with the through groove 202a in the gas passage pipe 202.

When the air passage pipe 202 is pressed towards the circular pipe 204b, the spiral strip 202c starts to be screwed into the spiral groove 204b-2, and the air passage pipe 202 cannot rotate, the switching member 204 rotates, so that the through hole 201j and the radial groove 204a-1 are completely overlapped, at this time, the cavity 201d is communicated with the through groove 202a in the air passage pipe 202, and the smoke is sucked from the air hole 202b for centralized treatment because of the negative pressure in the cavity 201 d.

Further, the timing chain 101 drives the hook 102 to rotate and support and transport the main plate 103 conveyed to the upper side of the weld pool in pairs, passing through the weld pool.

That is, only the straight line segment above the weld pool is located on the synchronous chain 101 in the working state, and when the air passage pipe 202 rotates along with the synchronous chain 101, the air passage pipes 202 symmetrically arranged start to contact and extrude each other in the process of closing from two sides to the middle, the air passage pipes 202 are extruded to the circular pipe 204b, and the switching piece 204 is driven to rotate, so that the air passage pipe 202 located on the straight line segment above the weld pool works.

This configuration provides the benefit of fewer simultaneous working airway tubes 202, fewer unnecessary passages, and increased negative pressure in the chamber when in operation.

Specifically, when the air passage tube 202 is not connected, the cavity 201d and the insertion groove 201f are still not communicated, so that the whole work is not influenced under the condition that the single air passage tube 202 is broken.

The hook 102 is provided with a perforation and a folded plate, the folded plate is arranged on the top of the relay box 201, the projection shaft 201b is sleeved with the perforation, and the sealing element 203 also plays a role in fixing the hook 102.
