When needing to use the chamber mirror trigger mechanism of this embodiment, the in-process of pinching trigger handle 2, pawl 6 and a certain spacing mouthful 8 joint of sawtooth rack 7, along with pinching the deepening of action, the in-process that trigger handle 2 is closer to fixed handle one side promptly, pawl 6 is to a propulsion effort of sawtooth rack 7 through spacing mouthful 8, and along with the lax of trigger handle 2, the in-process that trigger handle 2 kept away from for fixed handle promptly, pawl 6 breaks away from the spacing mouthful 8 of sawtooth rack 7 temporarily, in the pinching in-process to trigger handle 2 of another time, pawl 6 and another spacing mouthful 8 of sawtooth rack 7 (spacing mouthful 8 at this moment is the spacing mouthful 8 joint of the spacing mouthful 8 in-process of above-mentioned process). In the process of continuously repeating the pinching and loosening of the firing handle 2, the pawl 6 repeatedly interacts with the limiting port 8 of the sawtooth rack 7 to realize continuous propulsion of the sawtooth rack 7 and complete firing of the transmission assembly.
The connection frame 3 of the present embodiment is specifically connected with the elastic indicating plate and the elastic baffle plate in such a way that:
the connecting frame 3 is provided with a longitudinal notch 31 which is vertically distributed with the sawtooth strip 7; and a pair of transverse notches 32 which are communicated with the longitudinal notch 31 and are positioned at two sides of the longitudinal notch 31 are also arranged in the connecting frame 3. For the connecting frame 3 of this embodiment, a polymer plastic material can be selected.
The elastic indicating plate comprises a body 11 which is suitable for penetrating through the longitudinal notch 31 to partially extend into the strip-shaped opening 9, and a pair of oppositely extending wings 12 which are connected with one end of the body 11 far away from the sawtooth strip 7; the pair of wings 12 are adapted to fit in a one-to-one correspondence in the pair of transverse notches 32. The pair of wings 12 extending in opposite directions may be located on the same horizontal line or on different underwater lines, and this embodiment is not limited thereto. In addition, interference fit can be adopted between the wing 12 made of metal and the transverse notch 32 made of polymer plastic to realize the firm fit between the elastic indicating plate and the connecting frame 3.
Each pair of elastic baffles comprises a base body 13 which is suitable for penetrating through the longitudinal slot 31 and a bending body 15 which is connected with one end of the base body 13 far away from the sawtooth strip 7; the bending bodies 15 respectively included in the pair of elastic baffles are suitable for being embedded in the pair of transverse notches 32 in a one-to-one correspondence manner.

In addition, the present embodiment further includes a firing indication arrow 24 and a reset indication arrow 25, which are disposed at the edge of the slot of the sliding slot 17 and correspond to the sawtooth rack 7 to be fired in place, so that in the process of firing, since the reset button 16 moves synchronously with the sawtooth rack 7, in a specific firing process, not only a signal indicating that the firing is in place can be known through the prompt sound of the elastic indication plate, but also a signal indicating that the firing is in place can be known in combination with the alignment of the specific firing indication arrow 24 and the alignment arrow 23 on the reset button 16. In the process of resetting, along with the process that the reset button 16 drives the sawtooth rack 7 to move, the signal of resetting to the right position can be known through the prompt tone of the elastic indicating plate, and the signal of resetting to the right position can be known by combining the specific resetting indicating arrow 25 and the alignment arrow 23 on the reset button 16.
In summary, during the course of the movement of the sawtooth rack 7, a clear understanding of the advance of the sawtooth rack 7 can be achieved by the alignment of the alignment arrow 23 with the progress arrow 22.
