[0040] The transmission assembly 8 comprises a telescopic block 81, a buffer component 82 for reducing the telescopic speed of the telescopic block 81 and a plurality of blocking blocks 827.

The plurality of blocking blocks 827 are uniformly distributed on the inner wall of the second through hole 733.

[0041] The main drive shaft 9 comprises a connecting portion 91 and a sleeve portion 92. The tail end of the connecting portion 91 is provided with a connecting column 911. The tail end of the sleeve portion 92 is provided with a detachable cover 921. The outer wall of the sleeve portion 92 is provided with a telescopic groove which is slidably matched with the telescopic block 81. The connecting portion 91 is rotationally connected to the rotating seat 41. The head end of the sleeve portion 92 is fixedly connected to the connecting column 911. The buffer component 82 is arranged in the sleeve portion 92.

[0042] The buffer component 82 comprises a water storage tank 821 and a front stop disc 822, the water storage tank 821 is internally provided with a partition block 823, the partition block 823 divides the water storage tank 821 into a water storage area 824 and a transfer area 825, the water storage area 824 is internally provided with water and a piston 826 for driving the water to flow, one end of the piston 826 is provided with a pull rod 8261, one end of the pull rod 8261 penetrates the water storage tank 821, the other end of the piston 826 is provided with a second spring 8262, one end of the second spring 8262 abuts against the partition block 823, the partition block 823 is provided with a water passage hole 8231, the head end of the front stop disc 822 is provided with a protrusion 8221, the protrusion 8221 is provided with a third wedge surface 8222, the bottom of the telescopic block 81 is provided with an embedded block 812, the bottom of the embedded block 812 is provided with a fourth wedge surface 813 matched with the third wedge surface 8222, the water storage tank 821 is arranged in the sleeve portion 92, and the front stop disc 822 is fixedly connected to one end of the pull rod 8261.

[0043] The main drive shaft 9 drives the telescopic block 81 to rotate synchronously, the telescopic block 81 gradually approaches an obstacle block 827, the first wedge surface 811 on the telescopic block 81 abuts against the second wedge surface 8271, then the telescopic block 81 has a downward moving force, the telescopic block 81 transmits the force to the embedded block 812, the embedded block 812 transmits the force to the front stop disc 822 through the cooperation of the third wedge surface 8222 and the fourth wedge surface 813, the front stop disc 822 transmits the force to the pull rod 8261, the pull rod 8261 transmits the force to the piston 826, the force needs to overcome the second spring 8262 and the extrusion force of water movement to drive the piston 826 to move, at this time, the elastic force of the first spring 66 is smaller than the sum of the elastic force of the second spring 8262 and the extrusion force of water movement, the telescopic block 81 cannot be retracted into the telescopic groove, the telescopic block 81 can abut against the corresponding obstacle block 827 to drive the entire outer disc 73 to rotate, after the outer disc 73 rotates, the arc-shaped groove 732 drives the guide rod 713 to translate in the sliding groove 711, all the circular blocks 714 approach each other, the arc-shaped synchronous plate 742 also moves in the circumferential direction of the main drive shaft 9 when being gathered and driven by the circular blocks 714, the arc-shaped synchronous plate 742 drives the L-shaped rod 741 and the synchronous rod 62 to move synchronously, the synchronous rod 62 drives the sliding handle 65 and the arc-shaped stop block 64 to move synchronously, the arc-shaped stop block 64 moves away from the main shaft 21, and the welding wire disc 2 is unlocked.

[0044] After the guide rod 713 moves to the inner end along the arc groove 732, the guide rod 713 can no longer move, that is, the outer disk 73 cannot rotate, and all the obstruction blocks 827 cannot rotate synchronously with the outer disk 73. The obstruction blocks 827 form a blocking force on the telescopic block 81. This blocking force can overcome the obstruction force exerted by the second spring 8262 and the water movement on the piston 826, so that the telescopic block 81 can retract into the telescopic groove. The telescopic block 81 drives the inner block 812 to move synchronously. The inner block 812 drives the front abutment plate 822 to move towards the water storage tank 821 through the cooperation of the third wedge surface 8222 and the fourth wedge surface 813. The front abutment plate 822 drives the pull rod 8261 and the piston 826 to move synchronously. The second spring 8262 is squeezed, and the piston 826 can squeeze the water in the water storage area 824. The water can flow into the transfer area 825 through the water passage hole 8231.

[0045] When the telescopic block 81 disengages from the first obstruction block 827, the telescopic block 81 loses the obstructing force provided by the outer disk 73. The elastic force of the second spring 8262 will pull the piston 826 to move in the opposite direction, and the elastic force of the first spring 66 will also pull the guide rod 713 to move in the opposite direction within the slide groove 711. The guide rod 713 will use the arc groove 732 to drive the outer disk 73 to rotate in the opposite direction. At this time, the telescopic block 81 will extend out of the telescopic groove, and the extended part of the telescopic block 81 can abut against the next obstruction block 827, so that the outer disk 73 rotates in the forward direction again. Then the telescopic block 81 retracts into the telescopic groove, and so on. The arc abutment block 64 will experience left and right offset and shaking. However, when feeding wire, the arc abutment block 64 will not abut against the main shaft 21.

[0046] Furthermore, the water passage 8231 is frustoconical in shape, such as... Figure 9 As shown, the pressure on water when it is drawn from the transfer zone 825 into the storage zone 824 by the piston 826 is greater than the pressure on water when it is squeezed from the storage zone 824 into the transfer zone 825 by the piston 826. The purpose of increasing the pressure is to reduce the speed at which the telescopic block 81 extends out of the telescopic groove. When the main drive shaft 9 rotates, the volume of the extended part of the telescopic block 81 can be reduced. When the main drive shaft 9 stops, the reduced extension speed of the telescopic block 81 allows the outer disk 73 to rotate more smoothly in the opposite direction.

[0047] Furthermore, the cross-sectional area of ​​the built-in block 812 is larger than that of the telescopic block 81, and the built-in block 812 is used to limit the extension length of the telescopic block 81.

[0048] Furthermore, the main drive shaft 9 adopts a split structure, which facilitates the maintenance of the parts inside the sleeve section 92.

[0049] After the motor stops driving the output shaft 5 to rotate, the main drive shaft 9 also stops rotating. The elastic force of the first spring 66 drives the L-shaped rod 741 and the arc-shaped synchronous plate 742 to move in opposite directions synchronously. Then, the arc-shaped abutment block 64 immediately abuts against the main shaft 21 to perform emergency braking on the main shaft 21. At the same time, the guide rod 713 is also driven by the elastic force of the first spring 66 to move in opposite directions in the slide groove 711. The outer disk 73 rotates in opposite directions, and all guide rods 713 are reset. At this time, the elastic force of the second spring 8262 drives the piston 826 to move in opposite directions. The telescopic block 81 also loses the driving force brought by the motor. The telescopic block 81 extends out of the telescopic groove, and then the telescopic block 81 abuts against the obstruction block 827.

[0050] If the outer disk 73 does not fully reset when the telescopic block 81 abuts against the obstruction block 827, it will affect the braking effect. Therefore, a docking groove 51 for inserting the connecting part 91 is provided at the head end of the output shaft 5. Multiple drive blocks 52 are provided on the inner wall of the docking groove 51 at equal angles around its circumference. Multiple inner grooves 912 are provided on the outer wall of the head end of the connecting part 91 at equal angles around its circumference. The cross-sectional area of ​​the inner groove 912 is slightly larger than the cross-sectional area of ​​the drive block 52.

[0051] When the telescopic block 81 abuts against the obstruction block 827 before it is fully extended, the telescopic block 81 can be locked in this position. Through the cooperation of the drive block 52 and the inner groove 912, the main drive shaft 9 can rotate left and right by a certain angle. Figure 7 As shown, the driving force of the outer disk 73 rotating in the opposite direction causes the telescopic block 81 and the main drive shaft 9 to rotate in the opposite direction by a certain angle, thus ensuring that the outer disk 73 can be completely reset. When the motor is working, the output shaft 5 drives all the drive blocks 52 to rotate synchronously. After the drive block 52 abuts against one side of the groove wall of the inner groove 912, it can drive the main drive shaft 9 to rotate.
