The operation process is as follows:
the cylinder 46 contracts to drive the ball head 44 and further drive the wire claw 41 and the press head seat 43 to separate from the working table of the butt-welding equipment;
under the action of gravity, the slide rod head 31 of the slide rod 3 inclines downwards to drive the slide rod handle 32 to be separated from the groove plate 24 and fall into the groove of the pulley 23, and the slide rod 3 can freely stretch and retract through the pulley 23;
under the action of gravity, the slide rod 3 also drives the slide rod seat 2 to incline, further drives the hinge seat 17 to rotate around the hinge shaft of the hinge shaft seat 12, the slotted holes on the wing plates at the two sides of the hinge seat 17 drive the shifting ring 14 to lift, when the shifting ring 14 lifts, the close contact between the spline sleeve 13 and the conical surface of the hinge shaft seat 12 is removed, the hinge shaft seat 12 can freely rotate around the shaft part of the spline shaft 15, and the shifting ring 14 is sleeved on the spline sleeve 13 and can freely rotate, so the hinge seats 17 arranged on the hinge shaft seat 12 and the shifting ring 14, the slide rod seat 2 fixed on the hinge seat 17, the slide rod 3 and the pressure head 4 can rotate around the spline shaft 15;
through the operation, the slide rod 3 can freely stretch and contract and rotate around the spline shaft 15, so that the pressure head 4 can freely move in a certain area.

When the press head seat 43 presses the working table plate, the slide rod 3 is subjected to a reaction force, the slide rod handle 32 is disengaged from the pulley 23, falls into the groove of the groove plate 24 and is further locked and cannot slide, meanwhile, the slide rod 3 also drives the slide rod seat 2 and the fixed hinge buckle seat 17 to rotate around the hinge shaft of the hinge shaft seat 12, the slotted holes on the wing plates on the two sides of the hinge buckle seat 17 drive the shifting ring 14 to press downwards and press the spline sleeve 13 to be in close contact with the conical surface of the hinge shaft seat 12, the spline sleeve 13 cannot rotate under the spline action, and the friction force of the conical surface ensures that the hinge shaft seat 12 cannot rotate easily, and at the moment, the slide rod 3;
through the above operation, the ram 4 can stably press the stainless steel plate and the ground wire is well contacted to the stainless steel plate by the wire claw 41 by the cylinder 46.
