[0038] The utility model uses the following steps: when using the chain disassembly and assembly riveter with a magnetic double pressing head structure, when disassembling the chain plate, put the long and short push rods 9 into the mounting hole 7 at one end of the threaded rod 6, and let the short rod face outwards, and directly put the chain to be disassembled into the slideway 4 inside the seat body 1, and let the pin on the chain plate align with the blanking hole 3 on the seat body 1, and then screw the threaded rod 6 forward to let the threaded rod 6 drive the long and short push rods 9 to approach the pin on the chain plate and press it tightly, continue to screw the threaded rod 6 forward to make the pin disengage from one side of the chain plate, and then screw the threaded rod 6 in the reverse direction to let the long and short push rods 9 move away from the chain, pull out the long and short push rods 9 and reverse the direction to put them into the installation again The same operation is performed by screwing the threaded rod 6 forward so that the long rod of the long and short push rod 9 passes through the chain plate hole and presses against the pin again, and the threaded rod 6 continues to be rotated forward so that the pin is completely separated from the chain plate, and the pin slides out of the blanking hole 3 to complete the disassembly of the chain. It should be noted that in this process, the threaded rod 6 can be screwed forward with the aid of an electric wrench, but it is necessary to ensure that the inside of the first internal threaded hole 2 and the outside of the threaded rod 6 are oiled to ensure that the threaded rod 6 is smooth in the first internal threaded hole 2 to prevent damage caused by thread slippage. Then, when installing the chain plate, the pad 5 slides into the slideway 4 on the inner side of the seat body 1 and passes through The second magnet 14 fixes it, and then the pressure plate 11 is installed to one end of the threaded rod 6, so that the threaded rod 6 is inserted into the mounting groove 12 on one side of the pressure plate 11, and fixed by the third magnet 13, and then the pin is inserted into the chain plate hole, and the chain plate on one side of the pin is placed in the first groove 18 on the pad 5, and then the threaded rod 6 is screwed forward so that the threaded rod 6 drives the pressure plate 11 close to the chain plate until the chain plate on the other side of the pin enters the third groove 20 on the pressure plate 11 and fits with it. At this time, one end of the pin on the chain plate is located in the second groove 19, and the other end is located in the fourth groove 21. As the threaded rod 6 continues to be screwed forward, the chain plate is Tighten and combine with the pin, at this time, screw the threaded rod 6 in the reverse direction to drive the pressure plate 11 away from the chain plate, and then remove the pressure plate 11, put the expansion head 8 into the mounting hole 7, adjust the pin on the chain plate to the second groove 19 located in the middle position, and screw the threaded rod 6 forward again, so that the threaded rod 6 drives the expansion head 8 to rivet the pin on the chain plate, and finally complete the installation of the chain plate. In this process, in order to prevent cracking at both ends of the pin, it is recommended to use an ordinary wrench for manual operation. The riveter has a simple structure and is easy to use.
