As shown in fig. 1 to 7, in the first embodiment, the axial limiting member includes a first ball spring plunger 41 and a second ball spring plunger 42, the two ball spring plungers are disposed on the upper vertical rod 1 and axially distributed along the upper vertical rod 1, and an axial distance between the two ball spring plungers is equal to an axial length of the ferrule 3, as shown in fig. 7. As shown in fig. 10, since the ball plunger used in the first embodiment is an elastic member having elasticity, and the elastic member is located on the upper vertical rod 1, during the up-and-down movement of the ferrule 3, the ball 91 is pressed into the inner cavity 94 of the housing, the contracted ball 91 can abut against the inner wall of the ferrule 3, but the friction between the ball 91 and the inner wall of the ferrule 3 is small, so that the ferrule 3 can continue to slide in the axial direction under the condition of slight external force; when the wave bead 91 is no longer pressed by the inner wall of the cutting sleeve 3, the return force is extended again, and one end of the wave bead 91 protrudes out of the inner cavity 94 of the shell under the pushing force of the spring 93, namely protrudes out of the surface of the upper vertical rod 1; at this time, the ferrule 3 will be locked above the ball of the ball-end spring plunger one 41 without applying a downward force to the ferrule 3; since the distance between the first ball plunger 41 and the second ball plunger 42 is equal to the axial length of the ferrule 3, the ferrule 3 will be locked between the first ball plunger 41 and the second ball plunger 42, and the position of the ferrule 3 in the axial direction will be locked without external force.

As a preferred scheme, the axial position-limiting element may further include a ball-end spring plunger disposed on an inner wall of the ferrule 3 and a slot located on an outer wall of the front vertical rod and into which a ball of the ball-end spring plunger is clamped. In the upward sliding process of the cutting sleeve 3, when the wave bead of the ball-head spring plunger is intersected with the clamping groove and then clamped into the clamping groove, at the moment, the cutting sleeve 3 cannot move continuously in the axial direction under the condition of no external force, and the axial position of the cutting sleeve 3 is locked.

Besides the scheme of using the ball spring plunger, elastic silica gel can be simply arranged on the outer surface of the upper vertical rod 1, when the axial position of the cutting sleeve 3 needs to be locked, the cutting sleeve 3 is close to the silica gel part, and the silica gel is clamped into a gap space between the cutting sleeve 3 and the upper upright post 1, so that the friction force between the cutting sleeve 3 and the upper upright post 1 is increased; correspondingly, when the locking state needs to be released, only external force needs to be applied to the cutting sleeve 3 to enable the cutting sleeve 3 to be separated from the silica gel part.

Meanwhile, in the first embodiment, a radial limiting element is further added, and the radial limiting element includes a groove slide rail 52 extending along the axial direction and a slide block 51 capable of sliding along the groove slide rail; in the first embodiment, as shown in fig. 6, the groove slide rail 52 is a long-strip-shaped groove and is axially disposed on the outer wall of the upper vertical rod 1; the sliding block 51 is arranged on the inner wall of the cutting sleeve 3, clamped in the groove sliding rail 52 and can move up and down along the groove sliding rail 52; in the up-and-down moving process of the cutting sleeve 3, the sliding block 51 always slides in the groove sliding rail 52, so that the up-and-down moving track of the cutting sleeve 3 is locked, and the cutting sleeve 3 is ensured not to generate radial deviation in the axial moving process.
