As shown in Figure 13 and Figure 15,88 (not shown) three's built-up circuit of trigger switch 80, power supply 84 and prompting device will touch Switch 80 and ontology 10 is sent out to be connected, trigger switch 80 can with and only can be in free state and free state inside in push rod 82 Conducting, designs different driving circuits so that prompting device 88 can be driven to send out sound, light, vibrations etc. in compression stage slight distance Prompt mutation (for example, lamp do not work always it is bright suddenly, or light yellow does not work suddenly always), preferably buzzer, indicator light or micro- Type vibration motor etc. can allow the electromechanical original paper that people experiences.As long as by meeting known to principles above, and if only if reaching pair While being overlapped with the axis of guide rod 30 (claw 40 be rocked to first plane of symmetry 43) allows operator to experience the prominent of prompt when knife-like state Change can achieve the purpose that prompt, such as can design circuit and prompting device 88 is all only reached pair sending out prompt always It prompts to eliminate when knife-like state, realizes that the circuit design type of this function is various, the preferred trigger switch 80 of the present invention, 84 and of power supply 88 (not shown) three of prompting device forms series circuit, and when reaching to knife-like state, prompting device 88 just sends out prompt, that is, this implementation Example three.
Prompting device 88 can be integrated in inside trigger switch 80, and it is solid with centralizer to can also be used as an individual component Even, because arrangement is more flexibly convenient, it is also very readily conceivable that this is no longer described in detail in the present invention.Arrangement triggering The relative position of switch 80 and activation plate 45 so that overlapped with the axis of guide rod 30 when claw 40 is rocked to first plane of symmetry 43 When, trigger switch 80 is actuated by claw 40 just at conducting state, and driving prompting device 88 sends out the prompts such as sound, light, vibrations.
80 introduction about the construction of trigger switch is as follows.As shown in figure 16, trigger switch 80 is in free state, and push rod 82 is by limiting End and bar portion composition, bar portion can be slided in pilot hole, and pilot hole is connected with ontology 10, and 82 left side of push rod and positive stop end are solid Even, positive stop end is equipped with the second contact 821, and the right side of push rod 82 is equipped with third contact 822, the second contact 821 with and only touched with third 822 electrical connection of point.Pilot hole left side is equipped with the first contact 86, and the first contact 86 is insulated with pilot hole, and return element 83 is always Apply in the left side of push rod 82 and push rod 82 is turned right the power pushed away, under the action of this power, when trigger switch 80 is located at free shape When state, the second contact 821 and the first contact 86 are kept in contact;When push rod 82 is to limit extreme direction light exercise, the second contact 821 and first contact 86 be detached from be in electrical contact.4th contact 87 is connected with claw 40, and the 4th contact 87 is swung with claw 40, and the 4th Contact 87 can be from the distant to the near until contact with third contact 822, or detaches shape by being rocked to 822 contact condition of third contact State.
The specific electric system mode of connection is as follows.As shown in figure 16, one end of the pole electrical connection prompting device 88 of power supply 84, carries Show that the other end of device 88 is electrically connected the first contact 86, another pole of power supply 84 is electrically connected the 4th contact 87.The essence of wiring is to make It obtains and forms series circuit between power supply 84, prompting device 88, trigger switch 80 and the 4th contact 87, certainly in entire series circuit Increasing the attachmentes such as master switch, insurance, resistance, inductance and capacitance is also allowed, also within protection scope of the present invention, this hair It is bright to repeat no more.
80 principles and methods of trigger switch are as follows.As shown in figure 16, when claw 40 swing to middle process also not to it is middle when ( When first plane of symmetry 43 does not overlap with the axis of guide rod 30), the 4th contact 87 is not contacted with third contact 822, power supply 84, prompt Series circuit is formed between device 88, trigger switch 80 and the 4th contact 87 and is in off state, and prompting device 88 does not send out prompt letter Number.
As shown in figure 17, when claw 40 is rocked to Shaft alignment state, (i.e. first plane of symmetry 43 is overlapped with the axis of guide rod 30 When), the 4th contact 87 is just contacted with third contact 822, power supply 84, prompting device 88, trigger switch 80 and the 4th contact 87 it Between composition series circuit be in closed circuit state, prompting device 88 sends out standby signal, this position of prompting operator is Shaft alignment state.
As shown in figure 18, if operator's adjustment is excessive so that the swing of claw 40 has been more than that (i.e. first is symmetrical for Shaft alignment state When face 43 and the misaligned axis of guide rod 30), the 4th contact 87 pushes third contact 822 to be moved to the left, and overcomes return element 83 Returning place force so that the second contact 821 is disengaged with the first contact 86, and 80 internal break of trigger switch, power supply 84 is caused to carry Show that series circuit is formed between device 88, trigger switch 80 and the 4th contact 87 is in off state, prompting device 88 does not send out prompt Signal.
It can be seen that the ingehious design of trigger switch 80, and if only if the 4th contact 87 is contacted with third contact 822, together When the second contact 821 also to be contacted with the first contact 86, can just connect series loop and prompting device 88 is made to send out standby signal, As long as that is prompting device 88 sends out signal, claw 40 will be located at a specific, accurate position, when arrangement The relative position of contact 87 in pre-set trigger switch 80 and claw 40, so that it may to realize that claw 40 is rocked to centering shape Prompting device 88 sends out standby signal when state.It is learnt from the principle of trigger switch 80, even if mechanical part has the small of cooperation The flexible deformation influence in gap, system, it is also extremely that 80 4 contacts of trigger switch correspond to the displacement of push rod 82 when contacting simultaneously It is small.
