In this embodiment, the three columns are connected by bolts, the rear end of the delay tube is disposed in the central hole of the first column 38, the first delay powder column is disposed in the central holes of the second column 39 and the third column 40, and the second column is semicircular to form the installation cavity surrounded by the first column and the third column. The third column body is provided with an avoidance hole 41 for avoiding the inertia column.
Preferably, the pull rod can be arranged in a positioning groove on the outer wall of the firing tube, and the rear end of the pull rod sequentially penetrates through the three columns and is in contact with the sliding block.
The inertia post is used for carrying out secondary spacing to the slider, and its preferred reducing cylinder, the cylinder rear end that the radius is great is inserted in the dodging of third cylinder is downthehole, and the part that the radius is less is inserted between fuse casing and slider.
The front end face of the inertia column is provided with a spring groove 42, the rear end of the inertia spring is positioned in the spring groove, and the front end of the inertia spring is contacted with the first column body.
The rear end of the torsion spring seat can be provided with a spring positioning column 43, the front end of the torsion spring is sleeved on the torsion spring positioning column, and the other end of the torsion spring can be fixed on the third column body.

The slider is located between installation piece and the fuming agent casing, in this implementation, is equipped with front end open-ended mounting box 44 between fuming agent casing and the installation piece, and the slider is located the mounting box slidable, is equipped with the perforation with the intercommunicating pore intercommunication on the fuming agent casing on the mounting box rear wall. One end of the sliding block spring is contacted with the mounting box, and the other end of the sliding block spring is contacted with the sliding block.
When the shock absorber is used, the external equipment pulls the firing pin through the pull cover and the end cap, and meanwhile, the pull rod moves along with the firing pin until the end cap is completely separated from the firing pin. In the moving process, the firing pin compresses the firing spring, after the end cap is separated from the firing pin due to overlarge pulling force, the firing pin rapidly moves towards the fire cap under the elastic force of the firing spring until the needle head at the rear end of the firing pin strikes gunpowder in the fire cap. The powder in the fire cap is triggered and detonated due to the large impact force of the fire cap. The ignited fire cap ignites the time-delay powder column in the time-delay tube through the time-delay tube communicated with the fire cap, and the time-delay powder column starts to burn.
After the pull rod is pulled out, the rear end of the pull rod is moved out from one side of the slide block, so that the first safety of the slide block is released. Meanwhile, the limit of the driving arm is released because the pull rod is pulled out. At the moment, the torsion spring mounting seat rotates by a certain angle under the torsion action of the torsion spring so that the end part of the limiting arm moves out of the limiting groove of the inertia column, and the limiting arm is contacted with the inertia column to lock the inertia column. At this time, the rear end of the inertia column is located within the slider due to inertia.
After the multi-safety fuming fuse is launched, the speed of the multi-safety fuming fuse gradually becomes slower along with the continuous flight of the multi-safety fuming fuse. The end of the inertia post, which is originally located in the slider, is gradually moved out of the slider due to inertia. After the sliding block is completely moved out, the sliding block slides to the other side of the mounting box under the action of the elastic force of the sliding block spring, and at the moment, the middle hole of the sliding block is just aligned with the middle hole of the mounting block, namely the filling cavity. Along with the burning of time delay powder column, the second of the first biography powder column in the installation piece and the slider is lighted in proper order, and the last second passes the powder column and lights the medicament of fuming in the medicament of fuming casing, sends out the perforation transmission smog of medicament ignition back from fuze casing tip to realize the function of fuming.
From the above description, it can be seen that the multi-safety fuming fuse realizes two-safety through the arrangement of the pull rod and the inertia column, and the safety coefficient is higher.
