As shown in fig. 3, the manual glass breaking assembly 2 includes a handle cover 21, a glass breaking rod 22 and a limiting rod 23.

Wherein the hand flap cover 21 is arranged outside the shell 1. One end of the glass breaking rod 22 is connected with the bottom of the hand flap cover 21, and the other end of the glass breaking rod extends into the inner cavity of the shell 1 through the first through hole 13 on the upper shell 11.

One end of the limiting rod 23 is connected with the hand flap cover 21, and the other end extends into the limiting groove 14; and in the non-use state, the position of the limiting rod 23 staying in the limiting groove 14 is staggered with the second through hole 15 at the bottom of the limiting groove 14, so that the downward movement of the limiting rod 23 in the vertical direction is limited, and misoperation is prevented.

The manual glass breaking operation of the glass breaking device of the embodiment is as follows: the hand flap cover 21 is rotated to drive the limiting rod 23 to slide in the limiting groove 14; when the limiting rod 23 slides to the position right above the second through hole 15, the limiting of the limiting rod 23 in the vertical direction is released; at this time, the hand flap 21 is flap-down, and the end of the glass breaking rod 22 passes through the first through hole 13 in the lower case 12 to impact the glass for breaking.

It is noted that, in the present embodiment, the electric glass breaking assembly 3 may be a conventional technology, and the structure and the working principle thereof are not described herein.

According to the glass breaking device, through the arrangement of the electric glass breaking assembly 3 and the manual glass breaking assembly 2, the double functions of electric glass breaking and manual glass breaking can be realized; and the manual broken glass subassembly 2 carries out the spacing of vertical direction to gag lever post 23 through spacing groove 14 under the state of not using, can effectively prevent the potential safety hazard that brings because of the maloperation.

Example 2

Since in the above embodiment, the vertical limiting effect of the limiting groove 14 on the limiting rod 23 can be released only when the limiting rod 23 is required to be rotated to be right above the second through hole 15. The second through hole 15 is formed in the limit groove 14, so that the position relationship between the limit rod 23 and the second through hole 15 cannot be intuitively judged, and a certain trouble is brought to the releasing limit operation of the limit rod 23.

Therefore, in the glass breaking device of the present embodiment, the operator is assisted to judge the position between the stop lever 23 and the second through hole 15 by the external label.

Specifically, referring to fig. 3, the hand flap cover 21 and the upper housing 11 are provided with indication marks 25.
