(5) The output end of the electric telescopic rod drives the driving position inclined block to move downwards, so that two inclined planes of the electric telescopic rod contact two driving position wheels, the electric telescopic rod makes the electric telescopic rod move on the positioning substrate in a limiting manner through the multi-end round rod, the extrusion spring is in a buffering state, so that the driving position round ring moves, one side of the electric telescopic rod moves on the positioning substrate in a limiting manner through the positioning rod, the other side of the electric telescopic rod drives the stopping rod to move and is connected with the stopping groove, the limiting protruding block is limited at the current position, the two forbidden blocks cannot be reset, the control box can close the air pump, the connection of the shifting locking mechanism is disconnected, the shifting locking mechanism can also be enabled to continuously clamp the welding position, the energy is saved, the environmental protection effect is improved, the energy consumption caused by continuous supply of the shifting locking mechanism is avoided, and the limitation of the device in use is reduced.
(6) Through outwards pulling the stop limiting plate, the stop rod that makes to be equipped with on it is in the spacing removal of stop fixed block department, stop spring is in the state of buffering, thereby make stop rod no longer be connected with the stop groove, remove the spacing setting to the laminating pole, make upwards pulling laminating pole, make it in laminating base plate department spacing removal, laminating spring is in the state of buffering, make laminating clamp plate no longer contact with the terminal of electrode slice, thereby remove the spacing setting to the electrode slice, reset through guide spring, thereby pop out the electrode slice in the mounting groove, accomplish the dismantlement operation to the electrode slice.
(7) When the electrode slice is required to be installed, the tail end of the electrode slice stretches into the installation groove to contact the laminating pressing plate, the electrode slice is pressed downwards to enable the laminating pressing plate to move at the positions of the guide sliding groove and the guide rod in a limiting mode, the guide spring is in a buffering state, the laminating rod is pressed downwards to enable the electrode slice to move at the position of the laminating substrate in a limiting mode, the laminating spring is in a buffering state, so that the laminating pressing plate moves downwards to contact with the electrode slice, the stop rod is loosened, the stop rod is driven to move repeatedly through the reset of the stop spring and enters the stop groove, the guide rod is limited, the laminating pressing plate cannot be reset, the guide spring and the laminating spring are limited at the current position, at the moment, the guide spring provides upward force and acts on the bottom surface of the electrode slice, the laminating spring provides downward force to act on the top surface of the electrode slice, the electrode slice is clamped, meanwhile, the friction force of the laminating pressing plate and the electrode slice is increased through the rubber pad arranged, the phenomenon that the electrode slice slides when the electrode slice is used is avoided, and stability is improved; meanwhile, the mounting and dismounting operation of the electrode plate is finished, the replacement operation of the electrode plate by operators is convenient, and meanwhile, the replacement operation can be finished without other tools, so that the limitation of the device in use is reduced, and the mounting and dismounting efficiency is improved.

step two, gas generated by two output ports on one side of the air pump (4) enters a U-shaped pipeline (6) through two air inlet pipes (5) and sequentially passes through extrusion taper pipes (7) on two ends of the U-shaped pipeline (6), so that the gas enters an L-shaped circular pipe (9) and acts on a shifting round rod (12);
thirdly, the shifting round rod (12) is limited to move in the L-shaped round tube (9), so that the shifting round rod is propped against the shifting transverse plate (13) to move, the shifting round rod is limited to move on the extrusion substrate (10) through the shifting square rod (15) arranged on the shifting block (14), and the shifting spring (16) is in a buffer state;
and fourthly, the two shifting transverse plates (13) move in opposite directions, and the welding operation of the connecting position of the cutter is completed through the electrode plates (11) on the shifting transverse plates (13).
