Detailed Description

The working principle of the invention is described below with reference to the accompanying drawings:

the transmitter configuration is shown in fig. 1 and the transmitter guard off state is shown in fig. 2.

When the safety trigger 1 is in the 'F' position, the transmitter is in a safety closing state, the safety shaft 2 is positioned on the right side of the transmitter seat 3, and the sear 4 can be used for descending the piezoresistance iron spring 5, so that the on-hook operation can be carried out.

The hang-up procedure in the insurance off state is shown in fig. 3. The on-hook process under the insurance closing state is as follows: and the automatic machine 6 is pulled backwards to enable the tenons of the automatic machine 6 to lower the piezoresistance irons 4, when the tenons of the automatic machine 6 pass over the on-hook surfaces of the seastop irons 4, the seastop irons 4 are lifted upwards to return under the action of the seastop springs 5, and the on-hook surfaces of the seastop irons 4 are attached to the on-hook surfaces of the automatic machine 6, so that on-hook is completed.

The transmitter guard on state is shown in fig. 4. When the safety trigger 1 is placed in the "S" position, the transmitter is in the safety open state, with the safety shaft 2 on the left side of the transmitter housing 3, and the boss of the safety shaft 2 limits the sear 4 to be depressed.

The hang-up procedure in the insurance on state is shown in fig. 5. The on-hook process under the insurance opening state is as follows: the automatic machine 6 is pulled backwards, the tenon inclined surface on the automatic machine 6 acts with the safety shaft return lever 7, so that the safety shaft return lever 7 rotates anticlockwise, the safety shaft 2 is driven to move rightwards, the safety shaft return spring 8 is compressed, and at the moment, the automatic machine 6 can lower the piezoresistor 4, and then hanging is completed. After the hanging up is finished, the safety shaft 2 moves leftwards under the action of the safety shaft return spring 8 to drive the safety shaft return lever 7 to return clockwise, and the transmitter is still in a safety open state (S).

According to the invention, the safety shaft return lever is used as a conversion part, so that when the transmitter is in a safety open state, the transmitter can be hung up. Through the tenon inclined plane on the automaton and the return lever action of the safety shaft, the safety shaft is opened, so that the sear can be pressed down, and further the hanging machine is realized. After the hanging-up is completed, the safety shaft and the safety shaft return lever are reset under the action of the safety shaft return spring, so that the transmitter is restored to the safety opening state.

Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
