According to the grenade starting delay time switching mechanism, the fixing pin is provided with the stop pin which is perpendicular to the axial direction of the fixing pin.
In the grenade initiator delay time switching mechanism, the delay time of the first delay powder body is 3 s.
In the grenade initiator delay time switching mechanism, the delay time of the second delay powder body is 1.5 s.
Compared with the prior art, the utility model has the following advantages:
1. the utility model has simple structure, reasonable design and convenient realization.
2. The delay powder seat is provided with a first delay channel and a second delay channel, a first delay powder body is arranged in the first delay channel, a second delay powder body is arranged in the second delay channel, and the delay time of the first delay powder body is different from that of the second delay powder body.
3. The utility model designs the fixing pin, the ignition hole is arranged on the fixing pin, and the connection and disconnection between the ignition hole and the second delay channel are realized by rotating the fixing pin.
4. The method can be effectively applied to the grenade fuse, realizes delay time switching, improves tactical flexibility of grenade use, has good use effect and is convenient to popularize and use.
In conclusion, the grenade fuse has the advantages of simple structure, reasonable design, convenience in implementation, capability of being effectively applied to grenade fuses, capability of realizing delay time switching, improvement on tactical flexibility of grenades in use, good use effect and convenience in popularization and use.
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

Detailed Description
As shown in fig. 1 and 2, the grenade priming delay time switching mechanism of the utility model comprises a delay powder seat 1 and a fixing pin 2 positioned above the delay powder seat 1, wherein a first delay channel 3 and a second delay channel 4 are arranged in the delay powder seat 1 in parallel, and an output detonator 5 positioned below the first delay channel 3 and the second delay channel 4; a first delay gunpowder body 6 is arranged in the first delay channel 3, a second delay gunpowder body 7 is arranged in the second delay channel 4, one end of the fixing pin 2 is positioned above the second delay channel 4 and is provided with an ignition hole 9 which can be communicated with the second delay channel 4, and the other end of the fixing pin 2 is provided with a mode selection switch 10.
During specific implementation, the mode selection switch 10 is rotated manually to select a long delay (L) mode or a short delay (S) mode, and the mode selection switch 10 drives the fixing pin 2 to rotate, so that the ignition hole 9 and the second delay channel 4 are switched on and off.
In this embodiment, the fixing pin 2 is provided with a threaded sleeve 11, and the fixing pin 2 is connected to the fuse base body by the threaded sleeve 11.
In specific implementation, the fixing pin 2 penetrates through the threaded sleeve 11 and can rotate in the threaded sleeve 11, and the fixing pin 2 is connected with the fuse base body through the threaded sleeve 11.
In this embodiment, a seal ring 12 is disposed between the mode selection switch 10 and the screw sleeve 11.
In this embodiment, the mode selection switch 10 is provided with a lock pin rod 13, and a lock pin spring 14 is sleeved on the lock pin rod 13.
In particular, during rotation of the mode selector switch 10, the latch rod 13 is engaged with the fuse base by the latch spring 14.
In this embodiment, the fixing pin 2 is provided with a stop pin 8 perpendicular to the axial direction of the fixing pin 2.
In specific implementation, the mounting pin 2 is limited through the stop pin 8.
In this embodiment, the delay time of the first delay propellant 6 is 3 seconds.
In this embodiment, the delay time of the second delay powder body 7 is 1.5 s.
When the grenade fuse is used, the default state of the mode selection switch 10 is a long delay (L) mode, at the moment, the ignition hole 9 on the setting pin 2 and the second delay channel 4 are in a 90-degree dislocation state, the ignition flame output by a fire cap in the grenade fuse can be input only from the first delay channel 3, the second delay channel 4 is blocked by the setting pin 2, at the moment, the first delay explosive 6 of 3s is ignited, and the time from ignition to detonation of the output detonator 5 of the fuse is 3 s; when the fixing pin 2 rotates 90 degrees and is in a short delay (S) mode, the ignition hole 9 on the fixing pin 2 is communicated with the second delay channel 4, the ignition flame output by the fire cap simultaneously ignites the first delay explosive body 6 of 3S and the second delay explosive body 7 of 1.5S from the first delay channel 3 and the second delay channel 4, and the output detonator 5 is detonated after 1.5S.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
