In, the first return unit 51 is set on the first moving component 2, and the first return unit 51 is proximally and distally born against first
On baffle and the first limiting section 12, the first biasing force towards 4 side of the second moving component is applied to the first moving component 2.
Locating part 52 is slidably arranged relative between the first position and the second position of pedestal 1, for example, locating part 52 is
The pin shaft being threaded through on third moving component 61, accordingly first position and second of the third moving component 61 relative to pedestal 1
Slidably it is arranged between position.In first position, locating part 52 is located at proximal end and the second moving component 4 of the first moving component 2
Distal end between, locating part 52 does not act on the second moving component 4, locking effect is not played to the second moving component 4, at this time
Two moving components 4 can be moved relative to pedestal 1；In the second position, when the locating part 52 is with the third moving component 61
Proximal movement, specific as shown in fig. 6, the locating part 52 proximally first passes around the first guide surface 432 from distal end, institute at this time
It states locating part 52 and applies downward directed force F 1 to first guide surface 432, directed force F 1 drives second moving component 4
It moves downward, while the locating part 52 enters first passage 43 and continues to move to the near end and cross protrusion 431, then, institute
It is resetted upwards under the action of stating second return unit of second moving component 4 in the base assembly, the locating part 52 enters
It in stop zone 42 and is plugged in stop zone 42, reaches the second position, the second moving component 4 is locked in third movement portion
On part 61, accordingly, the second moving component 4 is in stationary state.
As shown in Figures 2 and 3, firing further includes third return unit 62 in equipment, and third return unit 62 is set in third fortune
On dynamic component 61；Third limiting section 14, such as annular slab are additionally provided on the inner wall of shell；The proximal end of third return unit 62 and
Distal end is born against in the proximal face of third limiting section 14 and the second moving component, and third return unit 62 gives the second movement portion
Part 4 applies the third biasing force towards 2 direction of the first moving component, and the third moving component is made to be held in the mounting portion
Proximal end face；Third biasing force is less than the first biasing force.For example, third return unit 62 can be spring.
Specifically, the position-limit mechanism and the engagement process of the stop zone 42 are as follows: firstly, percussion equipment is initial
In failure state, under the first partial pressure of the first return unit 51, since third biasing force is less than the first biasing force,
Under failure state, the resultant force of the first biasing force and third biasing force is still identical as the direction of the first biasing force, it is ensured that percussion is set
For under failure state, the first hinge joint 21 is the rotating fulcrum of operating member 31.Locating part 52 is located at the first moving component 2
First position between proximal end and the distal end of the second moving component 4, even if pressing operation component 31 at this time, operating member 31 cannot
It drives the first moving component 2 to move towards distal direction, cannot achieve percussion process；But the second moving component of driving is in third
