On the other hand, in the present embodiment, in order to prevent the movement of the nozzle pin 11 in the nozzle pin 11, the movement preventing projection 11b is prevented from moving forward by the fixing piece 106 is formed. Therefore, as will be described later, while the gas cylinder 103 is moved, the nozzle pin 11 and the gas cylinder 103 is implemented to enable the relative forward and backward movement. Of course, the fixing piece 106 may be formed integrally with the casing 101, or may be separately formed and mounted.

The injection button 105 allows the user to move the gas cylinder 103 by manual manpower. Therefore, one end 105a is in contact with the rear end of the gas cylinder 103 and the other end 105b is configured to protrude out of the casing 101, and the user protrudes out of the casing 101. The force is applied to the gas cylinder 103 by pressing 105b. As another application example for the injection button, it is possible to configure the rear end of the gas cylinder to extend and protrude to the outside of the casing, so that the rear end of the gas cylinder serves as the injection button.

When the release button 24 is pressed by the user, the control unit 23 rotates the motor 21 forward. The male screw shaft 21a is screwed into the female screw portion 22b of the locking member 22 by the forward rotation of the motor 21, and the locking member 22 is the movement preventing protrusion 22c and the guide. Since the rotational movement is prevented by the member 107, the screw is moved straight toward the motor 21 by the bite, so that the locking end 22a inserted into the locking groove 103a of the gas cylinder 103 is The lock is released as shown in FIG. 3 while exiting from the locking groove 103a.

When the user presses the injection button 105 after the nozzle pin 11 faces the abuser in the unlocked state, the gas cylinder 103 is advanced by the injection button 105. In other words, the nozzle pin 11 forbidden to move by the movement preventing protrusion 11b and the fixing piece 106 is moved backwards inwardly of the gas cylinder 103 while being elastically supported by the spring 12. Is the same as Therefore, the injection hole 11a of the nozzle pin 11 communicates with the inside of the gas cylinder 103, and the high pressure gas inside the gas cylinder 103 is strongly discharged toward the offender through the injection hole 11a.

On the other hand, if the user cancels the force applied to the injection button 105 after using the gas injection function, the gas cylinder 103 is returned to the state of Figure 1 by the elastic force of the spring 12, the user Presses the release button 24 again in order to return to the original locked state, the control unit 23 causes the motor 21 to rotate in reverse, and the male screw shaft 21a by reverse rotation of the motor 21. ) Reversely rotates to loosen the screw with the female screw portion 22b of the locking member 22. Therefore, the locking member 22 is advanced to the gas cylinder 103 side, and the locking end 22a is inserted into the locking groove 103a, thereby blocking the operation of the injection button 105.

Of course, according to an application example, the controller 23 rotates the motor 21 forward to release the lock when the user presses the release button 24, and after a predetermined time, for example, about 5 seconds. After the time elapses, the motor 21 may be rotated again to return to the locked state. In this case, it may be preferable in terms of eliminating the need for a separate operation to return to the user lock state.

Second Embodiment

If the user presses the release button 44 to release the lock state, the control unit 43 operates the motor 41 so that the eccentric side 42a of the locking member 42 is located on the side opposite to the gas cylinder. As shown by the dotted line in Fig. 4, the locking member 42 is rotated by 180 degrees to control the unlocking. At this time, it is preferable that the stopper 45 which can stop the rotation operation of the locking member 42 is provided on the opposite side of the gas cylinder 403 so that the locking member 42 can rotate only 180 degrees. That is, if the eccentric side 42a of the locking member 42 is caught by the stopper 45, the overload of the motor 41 will occur, and the control part 43 which recognized the overload of this motor 41 will be The operation of the motor 41 is stopped.

When the user operates the injection button 405 to inject the gas in the unlocked state, and then operates the release button 44 again, the control unit 43 rotates the motor 41 again 180 degrees to perform the operation of FIG. In the original state shown by the solid line, the eccentric side 42a of the locking member 42 is inserted into the locking groove 403a of the gas cylinder 403 to return to the locked state. Similarly, as an application example according to the present embodiment, after a predetermined time has elapsed after the user manipulates the release button 44, it may be implemented to return to the locked state again.

Third Embodiment

The teeth of 51a and the teeth of the ratchet member 51b are engaged with each other and are retracted in the b direction. Therefore, the locking member 52 hinged to the ratchet member 51b is retracted while being elastically supported by the restoring spring 54, thereby exiting from the locking groove 503a of the gas cylinder 503.

Such a configuration is preferable because a vibration motor configured in the existing mobile telephone terminal can be used. That is, when the vibration motor rotates in the clockwise direction, the vibration is generated, and when the vibration motor rotates in the counterclockwise direction, the lock is released to switch to a state capable of gas injection.

Even in this case, when the user operates the release button 55 to input the unlock command, the controller 54 causes the motor 51 to rotate counterclockwise only for a predetermined time, and then when a predetermined time elapses. It is also desirable to implement such that it can be controlled to stop the operation of the motor 51. When the operation of the motor 51 is stopped, the locking member 52 is advanced toward the gas cylinder 503 by the elastic force of the restoring spring 54, so that the locking end 52a of the locking member 52 moves to the gas cylinder. It is inserted into the locking groove 503a of 503 to return to the locked state.
