[0027] Furthermore, in order to ensure that the welding gun head remains connected to the fixed pipe after the angle is adjusted, a plurality of channels are opened on one side of the connecting block 301, and the channels are connected to each other and are distributed in a 90-degree circle.
[0028] Furthermore, in order to facilitate temporary locking of the locking rod and adjustment, two protrusions 311 are fixedly connected to one side of the locking rod 303, and a mounting plate 312 is provided on one side of the locking rod 303, and one side of the mounting plate 312 is fixedly connected to one side of the annular block 309, and a sliding hole is opened on one side of the mounting plate 312, and the interior of the sliding hole is movably connected to one side of the locking rod 303, and a convex groove is opened on one side of the sliding hole, and the interior of the convex groove is movably connected to one side of the protrusion 311, and two limit blocks 313 are fixedly connected to one side of the mounting plate 312, and a positioning plate 314 is movably connected to one side of the sliding rod 305, and one side of the positioning plate 314 is fixedly connected to one side of the fixed tube 310.
[0029] One of the two protrusions 311 is close to the limiting plate 304 , and the other is far away from the limiting plate 304 .
[0030] Handheld multifunctional welding gun, the working principle is as follows:
[0031] When the angle of the welding gun head 2 needs to be adjusted, the operating ring 308 is first pulled, and the operating ring 308 drives the sliding rod 305 to move. The sliding rod 305 drives the limiting plate 304 to move, and drives the baffle 306 to move, so that the spring 307 is compressed, and the limiting plate 304 drives the locking rod 303 to move, so that the locking rod 303 is disengaged from the current locking hole, and the protrusion 311 on the locking rod 303 moves accordingly. When the protrusion 311 away from the limiting plate 304 completely passes through the protruding groove on the mounting plate 312, the operating ring 308 is rotated to make the limiting plate 304 rotate, drive the locking rod 303 and the protrusion 311 to rotate, so that the protrusion 311 contacts one of the limiting blocks 313. At this time, the protrusion 311 is blocked and the spring 307 cannot be reset. Then, the welding gun head 2 is adjusted according to the required angle. The welding gun head 2 is adjusted to drive the connecting block 301 to rotate, so that the corresponding channel is connected to the inside of the fixing tube 310, and the remaining channels are closed inside the annular block.
[0032] After the angle is adjusted, the operating ring 308 is reversed to deflect the protrusion 311. When the protrusion 311 contacts another limit block 313, the position of the protrusion 311 corresponds to the position of the protrusion groove, and the operating ring 308 is released. The spring 307 is no longer under force, and the baffle 306 is pushed under the force of the spring 307, pushing the limit plate 304 and driving the locking rod 303. The locking rod 303 is inserted into another locking hole to complete the adjustment. At this time, the operating ring 308 can be rotated again to deflect the protrusion 311 contacting the limit plate 304 until it contacts one of the limit blocks 313, thereby avoiding the situation where the welding gun head 2 is unlocked due to accidental touching of the operating ring 308.
