Referring to fig. 2, the mating relationship of the outer housing 41 and the inner housing 42 is shown. The inner shaft body 42 is cylindrical, the outer shell 41 is a sleeve structure matched with the inner shaft body 42, a fixing hole 423 is radially arranged on the inner shaft body 42 along the inner shaft body, a limiting part 43 is arranged in the fixing hole 423, two different limiting positions 411 are arranged on the inner wall of the outer shell 41 corresponding to the limiting part, the limiting part 43 on the inner shaft body 42 is switched at the different limiting positions 411 to limit the position of the inner shaft body 42 moving axially in the outer shell 41; the end of the inner shaft body 42 is provided with a clamping groove 421, the clamping groove 421 has an opening 422, the clamping pin 30 is clamped into the clamping groove 421 along the opening 422, and the inner shaft body 42 is respectively positioned at different limiting positions at a position where the clamping groove 421 assembled with the clamping pin 30 is exposed and at a position where the clamping groove 421 assembled with the clamping pin 30 is completely shielded.

Referring to fig. 2 and 3, the position-limiting member includes an elastic element and a position-limiting pin, and the position-limiting member has two different embodiments, in embodiment 1, the elastic element 431 is a spring, the position-limiting pin 432 is a bayonet pin, the position-limiting member is fixedly clamped in the assembly structure of the inner shaft body 42 and the outer housing 41, one end of the position-limiting pin 432 near the elastic element 431 is provided with a protrusion 433, and the position-limiting pin 432 presses the elastic element 431 through the protrusion 433 and is clamped into the fixing hole 423. The limiting member is supported at a limiting position 411 of the inner wall of the outer shell by the elasticity of the elastic element, the limiting position 411 is an annular groove circumferentially surrounded by the inner wall, the limiting position 411 comprises a first annular groove, a second annular groove and a connecting part 412 communicated with the two annular grooves, and the depth of the connecting part 412 is greater than 0 and smaller than the two annular grooves; when the inner shaft body is pulled in the axial direction, the inner shaft body moves outwards to drive the limiting piece to slide at the limiting position, and the limiting piece slides to the first annular groove from the second annular groove through the connecting part and stops, and the inner shaft body is limited at the limiting position; when the inner shaft body is pushed in the axial direction, the inner shaft body moves inwards to drive the limiting piece to slide at the limiting position, and the limiting piece slides to the second annular groove from the first annular groove through the connecting part and stops.

A limiting platform 424 is arranged in the fixing hole, and when the bayonet compression spring is assembled in the fixing hole 423, the limiting piece 42 is limited by the limiting platform 424 to the deepest position of the fixing hole 423, namely, the height of the limiting piece integrally extending out of the surface of the inner shaft is limited. The maximum height Hmax and the minimum height Hmin of the inner shaft body surface respectively meet the following conditions: hmax > the depth of the annular groove and Hmin > the gap between the inner shaft body and the outer shell.

Referring to fig. 4 and 5, there is shown another embodiment of the position limiter, in which the elastic element 431 is a spring, the position limiting pin 432 is a spring pin, one end of the spring pin near the spring is provided with a boss 433, and the middle section of the spring pin is provided with a locking cone 434; wherein boss 433 chucking compression spring is in the locating part fixed orifices, from draw-in groove 421 to locating part fixed orifices 423 open one locking groove 425, can dismantle locking piece 44 along locking groove 425 stretch into wherein and withstand this locking taper ring 434, when can dismantle locking piece 44 twist totally in locking groove 425 and withstand the locking taper ring 434 center of bullet round pin, in fact push down towards the direction that stretches into in the fixed orifices, at this moment, the whole retraction of bullet round pin is in the fixed orifices 423, at this moment, interior shaft 42 surface does not have protruding position, can follow the interior slip-off of shell body. The process of separating the outer housing 41 and the inner shaft body 42 is achieved. Referring to fig. 5, in normal use, because the detachable locking member 44 is in a slightly retracted state, and the tip thereof is in a retracted state, and is not pressed against the center of the locking cone 434, the elastic pin is pushed out of the surface of the inner shaft 42 under the elastic force of the spring and is clamped into the limit position of the outer housing 41, so that the elastic pin cannot be released from between the inner shaft 42 and the outer housing 41, and can only be inserted into the fixing hole 423 of the inner shaft 42, thereby integrally clamping the inner shaft 42 in the outer housing 41 and limiting the inner shaft 42 to move only in the outer housing 41, and cannot be released. If the detachable locking member 44 is screwed completely into the deepest position along the locking groove 425, the tip of the detachable locking member 44 is pushed up along the inclined surface to the center of the locking cone 434 of the elastic pin, and the outer surface of the inner shaft has no projection, the inner shaft 42 can be slid out of the outer housing 41, and the small parts can be replaced by themselves.
