[0020] like Figure 2 , Figure 3 As shown, the main components of this utility model are clamping rod 1, connecting disc 2, fastening screw 3, upper chuck 4, spring 5, positioning cylinder 6, soft claw 7, three-jaw chuck 8, flange 9, and screw 10.

[0021] Functionally, this utility model includes a cartridge extraction tool, and the assembly process is as follows: Figure 2 , Figure 3 , Figure 4 .

[0022] The upper clamping mechanism consists of a clamping rod 1, a connecting plate 2, a fastening screw 3, and an upper chuck 4. The clamping rod 1 is a stepped shaft-type part, with the upper part being a slender shaft and the lower end being an external thread.

[0023] The connecting disc 2 is annular in shape, with a threaded upper part on the inner ring and a protruding step on the lower part (i.e., a disc on the outer circumference). The upper chuck 4 is also annular in shape, consisting of two semi-circular parts that can be separated in the middle. The upper part of the upper chuck has an inner circular hole in its center with grooves on the wall of the hole, and the lower part has a small circular hole in its center, cut in half. There are matching threaded holes between the lower outer circumference disc of the connecting disc 2 and the upper part of the upper chuck 4 for connection with screws.
