[0022] A circular hole for mounting the endoscopic probe 5 is provided in the guide head 3 .

[0023] refer to Figure 3 、 4 , the use process of this utility model is as follows,

[0024] 1. Disassembly process of the magnetic ring: First, slowly push the push jack magnetic ring disassembly tool from the right side port of the piston rod 6 to the position of the magnetic ring 8, observe the endoscope probe 5, and ensure that the tool can smoothly enter the narrow inner hole on the right side of the piston rod 6. The front end face of the guide head 3 is tapered and has a guiding function. The center hole of the magnetic ring 8 is coaxial with the guide head 3. Ensure that the guide head 3 enters the center hole of the magnetic ring 8 first, and then the end face of the claw 2 can be seen through the endoscope probe 5 to contact the end face of the magnetic ring 8. By slowly rotating the handle 4, ensure that the claw 2 is smoothly inserted into the two positioning holes 10 of the magnetic ring 8, and then rotate the handle 4 in the opposite direction to twist the magnetic ring 8 and remove the magnetic ring 8.

[0025] 2. Installation process of the magnetic ring: First, insert the positioning hole 10 on the end face of the magnetic ring 8 into the claw 2.

Finally, pull the force rod 1 outward.

[0026] During the specific operation, since the center hole of the magnetic ring 8 is shallow, the magnetic ring 8 may slip off the claw 2 during the process of disassembly and outward removal. Since the guide head 3 in this tool is long, it can firmly catch the magnetic ring 8, ensuring that the magnetic ring 8 will not fall into the narrow inner hole of the piston rod 6 after removal, so that the magnetic ring 8 can be smoothly removed.
