Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1, fig. 2 and fig. 3, a starting mechanism for a fire extinguisher in the drawings includes a fire extinguisher body 1, a spraying pressure handle 2 is arranged on the fire extinguisher body 1, the spraying pressure handle 2 is a conventional arrangement on the fire extinguisher, so details are omitted, the fire extinguishing operation is convenient to operate, a fixing mechanism is arranged on the spraying pressure handle 2, the fixing mechanism is arranged to avoid the long-time hand pressure of the spraying pressure handle 2 during fire extinguishing, the hand pressure is reduced, the fixing mechanism comprises a box 36, the box 36 is square, the box 36 is arranged to facilitate the sliding of a limit block 33, the box 36 is fixedly arranged on the inner wall of the spraying pressure handle 2, the box 36 is internally provided with a limit block 33 in a sliding manner, and the limit block 33 is arranged to facilitate the installation of the limit block 34.

One end of the limiting block 33 penetrates through the box 36 and is rotationally connected with the sliding block 34, the sliding block 34 is square, sliding on the sliding rail 35 is facilitated, the sliding rail 35 is arranged on the inner wall of the injection pressing handle 2, the sliding rail 35 is arranged, sliding of the sliding block 34 is facilitated, the sliding block 34 slides on the surface of the sliding rail 35, a first spring 37 is arranged in the box 36, the first spring 37 is in a compressed state, one end of the first spring 37 is fixedly connected with the bottom end of the limiting block 33, a second spring 31 is arranged on the side face of the box 36, a plug pin 32 is arranged at one end of the second spring 31, the cross section of the plug pin 32 is T-shaped, one end of the plug pin 32 is inclined, one end of the plug pin 32 penetrates through the box 36, a slot 38 is formed in the side face of the limiting block 33, the slot 38 is square, and through the arrangement of the slot 38, the connection of one end of the plug pin 32 is facilitated, and the number of the slots 38 is two.
