The linkage driving motor 616 is operated to drive the linkage driving spindle 612 to rotate through the first linkage driving wheel 613, the linkage driving belt 615 and the second linkage driving wheel 614. The plugging and pressing linkage worm sleeve 6201 mounted on the linkage driving main shaft 612 drives the plugging and pressing linkage cam 6204 to rotate through the plugging and pressing linkage worm wheel 6202 and the plugging and pressing linkage main shaft 6203, because the plugging and pressing linkage cam 6204 is eccentric, in the process of rotating the plugging and pressing linkage cam 6204, under the action of a V-shaped plugging and pressing linkage swing rod torsion spring 6207, the V-shaped plugging and pressing linkage swing rod 6205 swings anticlockwise around a V-shaped plugging and pressing linkage swing rod pin 6206, so that the plugging and pressing linkage transmission wheel 6208 is always attached to the plugging and pressing linkage cam 6204, the plugging and pressing linkage swing rod 62011 drives the L-shaped plugging and pressing linkage swing rod 6209 to swing anticlockwise around an L-shaped plugging and pressing linkage swing rod pin 6210, and a U-shaped plugging and pressing fork 12 mounted at the upper end of the L-shaped plugging and pressing linkage swing rod 6209 drives the step plugging and pressing sliding table plugging and sliding table 4201 to slide leftwards along the step plugging and pressing support seat 4202 through a plugging and pressing fork wheel 6213. When the step table plug pressure sliding table 4201 slides leftward, the swing transmission gear 4207 of the upper jaw mounted at the right end of the swing upper jaw 4204 swings clockwise around the upper jaw pin 4205, the ring-plate type clamp plate at the left end of the swing upper jaw 4204 swings upward and opens, the swing upper jaw 4204 and the ring-plate type clamp plate at the left end of the fixed lower jaw 4203 enter the right end of the step table 7, and as the step table plug pressure sliding table 4201 continues to slide leftward, the swing upper jaw 4204 swings counterclockwise around the upper jaw pin 4205 and closes, the swing upper jaw 4204 and the fixed lower jaw 4203 clamp the step shaft, and the step table lifting cylinder 41231 operates to drive the step table support 4122 to rapidly move downward and reset, thereby preventing the step table support 4122 from blocking the step table 7 from moving leftward. When the step table stopper sliding table 4201 continues to slide leftward, the step table 7 is stopped in the step table mounting groove 311 of the end cover tray 31. Meanwhile, a first O-shaped ring feeding linkage bevel gear 631 mounted on the linkage driving main shaft 612 drives an O-shaped ring feeding linkage crank 635 to continuously rotate through a second O-shaped ring feeding linkage bevel gear 632 and an O-shaped ring feeding linkage main shaft 633, the O-shaped ring feeding linkage crank 635 drives an O-shaped ring feeding slide block 5121 to slide rightwards along an O-shaped ring feeding track 5122 through an O-shaped ring feeding linkage connecting rod 636, meanwhile, the O-shaped ring feeding plunger support 5125 is driven to move rightwards by the I-shaped synchronous connecting frame 5123, the O-shaped rings intermittently fall from the O-shaped ring feeding channel 511 one by one for feeding, the two O-shaped ring feeding plungers 5124 arranged on the O-shaped ring feeding plunger support 5125 just receive the O-shaped rings falling from the O-shaped ring feeding channel 511, the plunger limit piece 5126 limits the O-shaped rings, and the O-shaped rings are conveyed to the left end of the sleeving guide swing rod 5203 along with the continuous rightward movement of the two O-shaped ring feeding plungers 5124. Then, the driving cylinder 5206 is guided to move to drive the guide seat 5212 to move leftward, the sleeved guide swing rod 5203 is driven to swing around the sleeved guide swing rod pin 5205 through the guide pull rod 5207, the left end of the sleeved guide swing rod 5203 is gradually opened, the right end of the sleeved guide swing rod 5203 is gradually closed until the guide inclined plane attaching table 52031 at the right end of the sleeved guide swing rod 5203 is attached to the left end of the step table 7, and in the opening process of the left end of the sleeved guide swing rod 5203, the O-shaped ring is expanded, slides rightward along the sleeved guide swing rod 5203, and is finally sleeved in the O-shaped ring mounting groove 71 at the end of the step table 7. The position of the nested guide swing rod 5203 and the position of the two O-shaped ring feeding plunger 5124 are staggered to avoid interference, and in addition, the left end of the nested guide swing rod 5203 is provided with an anti-dropping ear 52032, thereby effectively avoiding the O-shaped ring from dropping from the left end of the nested guide swing rod 5203. As the O-ring feeding linkage crank 635 continues to rotate, the O-ring feeding linkage link 636 drives the O-ring feeding slider 5121 to slide leftward along the O-ring feeding track 5122, and simultaneously drives the O-ring feeding plunger support 5125 to move leftward through the I-shaped synchronous link 5123, so as to reset and prepare for the next O-ring feeding. Then, the guiding driving cylinder 5206 acts again to drive the guiding seat 5212 to move rightwards, and the guiding pull rod 5207 drives the sleeving guiding swing rod 5203 to swing around the sleeving guiding swing rod pin 5205, the left end of the sleeving guiding swing rod 5203 is gradually closed, and the right end of the sleeving guiding swing rod 5203 is gradually opened to realize resetting, so that preparation is made for the next sleeving. After the O-shaped ring is sleeved, the plugging linkage cam 6204 drives the V-shaped plugging linkage swing rod 6208 to swing clockwise around the V-shaped plugging linkage swing rod pin 6206 through the plugging linkage transmission wheel 6208, drives the L-shaped plugging linkage swing rod 6209 to swing clockwise around the L-shaped plugging linkage swing rod pin 6210 through the plugging linkage transmission rod 6211, and drives the step table plugging sliding table 4201 to slide rightwards along the step table plugging support seat 4202 through the U-shaped plugging fork 6212 installed at the upper end of the L-shaped plugging linkage swing rod 6209 through the plugging fork wheel 6213.
