Abstract
A dental striking wrench with caution device contains a dental striking handle. And a dental strike is arranged on the dental striking handle. The utility model is characterized in that the two sides of the dental strike are respectively arranged with a connecting leg. A conductor is arranged between the two connecting legs. A circuit arrangement is connected on the conductor by wire. The circuit arrangement connects at least one power supply to provide power for the circuit, a switch to control the circuit, a resistance to regulate the current in the circuit, and an indicator light as caution in series. The power supply, switch, resistance and the indicator light are connected together to form a pathway.
Description
Technical field
The utility model relates to a kind of tapping spanner, particularly relates to a kind of tapping spanner with alarming device.
Background technology
Using the tapping spanner, during tapping, attack that snaggletooth is attacked or thread is attacked less than projected depth, is problem common in mould and the machining.Its main cause is, when tapping, tapping spanner and workpiece are not easy to be found when not parallel, fails in time to correct, and it is askew to make thread attack.
Therefore, in time monitor the collimation of tapping spanner and workpiece, and rectification error, just can avoid the generation of adverse events, prolong the service life of tapping spanner.
Summary of the invention
For addressing the above problem, the utility model proposes a kind of tapping spanner with alarming device, solved tapping spanner and workpiece and be not easy to be found when not parallel, and the problem that can not in time correct.
The technical solution of the utility model is: a kind of tapping spanner with alarming device, and it is provided with a tapping handle, is equipped with a tooth and attacks on the tapping handle, wherein, by the both sides that above-mentioned tooth is attacked, respectively is provided with a pin; Simultaneously, between above-mentioned two pins, be conductor, use lead on it, be connected with a circuit arrangement, this circuit arrangement is in series with at least one power supply, a switch, a resistance, an indicator lamp, and these power supplys, switch, a resistance and an indicator lamp link together, and forms path; When tapping, if the tapping spanner is parallel with workpiece, then tooth two pins of attacking side touch simultaneously by the conductor of tapping, above-mentioned series circuit is understood conducting, indicator lamp is bright; Otherwise tapping spanner and workpiece are not parallel, then tooth two pins of attacking side can not touch simultaneously by the metal of tapping, indicator lamp does not work; Judge that with this whether parallel tapping spanner is with workpiece.
Above-mentioned conductor pins, the position that contacts with the tapping spanner is provided with insulator, avoids pin and the not conducting of tapping spanner; Pin be set to spheric conductor by the conductor contact jaw of tapping, make pin both can with contacted conducting by the tapping conductor, too big friction can not arranged with it again, avoid mutual infringement.
The circuit arrangement of above-mentioned two pins and series connection is limited in the device, is convenient to the dismounting of this alarming device, when when restricted, being pulled down this alarming device by the workpiece of tapping.
The device of above-mentioned qualification two pins and series circuit is insulation, transparent material, convenient to indicator lamp observation and prevent the crust of the device conduction.
Power source voltage is a safe voltage in the above-mentioned series circuit, prevents from human body is damaged.
Tapping spanner of the present utility model utilizes the whether parallel of alarming device monitoring tapping spanner and workpiece, as not parallel timely correction, reaches and prevents to attack that snaggletooth is attacked or thread is attacked purpose less than projected depth.

The circuit diagram of Fig. 2 the utility model circuit arrangement.
Fig. 3 generalized section of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing in detail one of the utility model embodiment is described in detail.
As Figure 1-3, a kind of tapping spanner with alarming device, it is provided with a tapping handle 10, be equipped with a tooth in the centre position of tapping handle 10 and attack 11, this tooth attack 11 with the junction of tapping handle 10 be that a surface is that rectangular space tooth is attacked 11 and is arranged on rectangular center, it is 11 detachable that this tooth is attacked, and the convenient back of damaging is changed; Wherein, attack at above-mentioned tooth by 11 the both sides, respectively be provided with a pin 12, be equipped with two holes in position, a rectangular diagonal angle, tapping handle 10 above-mentioned surfaces, pin 12 is placed wherein, this pin 12 attacks 11 at same diagonal with the tooth at center.
Simultaneously, 12 of above-mentioned two pins, use lead, be connected with a circuit arrangement 120, this circuit arrangement is in series with at least one power supply E, a switch 121, a resistance R, an indicator lamp 122 (as shown in Figure 2), these power supplys E, switch 121, a resistance R and an indicator lamp 122 link together, and form path; Power supply E in the series circuit provides electric weight for entire circuit, and voltage available is the battery of 1.5V, and resistance R is in order to the circuit in the regulating circuit, but the switching of 121 control circuits of switch; In addition, the circuit arrangement 120 of two pins 12 and series connection then is limited in the device of an insulation, transparent material, and the dismounting of this alarming device also is convenient in convenient observation to indicator lamp 122, when when restricted, being pulled down this alarming device by the workpiece of tapping; And, above-mentioned conductor pins 12, the position that contacts with the tapping spanner is provided with insulator, avoids pin 12 and the not conducting of tapping spanner; Pin 12 be set to spheric conductor by the conductor contact jaw of tapping, make pin 12 both can with contacted conducting by the tapping conductor, too big friction can not arranged with it again, avoid mutual infringement.
When tapping, if the tapping spanner is parallel with workpiece, then tooth two pins 12 of attacking 11 sides touch simultaneously by the metal of tapping, above-mentioned series circuit is understood conducting, indicator lamp 122 is bright; Otherwise tapping spanner and workpiece are not parallel, then tooth two pins 12 of attacking 11 sides can not touch simultaneously by the metal of tapping, indicator lamp 122 does not work; Judge that with this whether parallel tapping spanner is with workpiece.
Tapping spanner of the present utility model utilizes the whether parallel of alarming device monitoring tapping spanner and workpiece, as not parallel timely correction, reach prevent to attack snaggletooth attack 11 or thread attack purpose less than projected depth.
