Embodiment

With reference to Fig. 1 a, 1b, Fig. 1 a, 1b are two skeleton views that the utility model first embodiment is shown, and device wherein of the present utility model is attached to be placed on the existing hammer.At Fig. 1 a, among the 1b, 10 is tup; The 11st, hammer handle; The 12nd, the housing of encirclement Electrical and Electronic element, it can be installed on the appropriate location by belt; The 13rd, the column detector of contact spring form; The 14th, selector switch; The 15th, be used to select the operating switch of column pattern or AC mode; The 16th, the interchange detector of multiturn coil form.Should add the rubber blanket (not shown) that 2mm is thick at least between housing 12 and hammer handle is used for shockproof.Certainly, any known shock absorbing element all can be used for this purpose.

With reference to Fig. 5, when operation, tup is placed on the wallboard, then, the user uses thumb push switch 15, and at this moment, the user serves as the earth element of device of the present utility model and plays the effect of powering into IC28, thereby, automatically calibration beginning, LED (Fig. 1 a, not shown among the 1b) is luminous.If column/alternating voltage is just in time arranged below

detector

13 or 16, then LED will be luminous.If just in time there is not column/alternating voltage below

detector

13 or 16, then LED just can not be luminous.

Fig. 2 is the individual skeleton view that the utility model second embodiment is shown, and wherein, device of the present utility model is set in the hammer of special manufacturing.Because in this embodiment, hammer and device of the present utility model are made and assembling by same factory, and therefore, being connected between hammer and the device of the present utility model is embedding and sightless.

Fig. 3 is the skeleton view that the utility model the 3rd embodiment is shown, and wherein, device of the present utility model is installed with on existing hammer.Fig. 3 and Fig. 1 a, 1b is closely similar, except Fig. 1 a, outside the column detector 13 among the 1b is replaced by 13 among Fig. 3 '.This is with simplified structure.

Fig. 4 is the skeleton view that the utility model the 4th embodiment is shown, and device wherein of the present utility model is installed with on the nail rifle.In this embodiment, circuit and Fig. 1 a, that uses among the 1b to Fig. 3 is identical.The column detector with exchange detector and can both be wrapped near the rifle mouth (not shown) any metalwork.Other metalwork also can be used for this purpose.

Fig. 5 is a circuit diagram of the present utility model.In Fig. 5, all Electrical and Electronic elements all are installed on the printed circuit board (PCB) (not shown).IC (IC28) connects two LED and a hummer, and when reality is used, can use three LED, for example, a LED who is used for representing to find column, a LED who is used for representing to find alternating voltage, and the 3rd LED that is used for representing not find any target.Hummer also is optional.Operating switch has two functions, and one is to be used for making IC ground connection by the operator, and another is used to select the function selecting of AC mode.

Although all above-mentioned embodiment have selector switch, those skilled in the art can change over the circuit that does not need selector switch with the circuit diagram among Fig. 5 easily.For example, under the situation of using two IC.So, any instrument (such as, hammer, electric drill, nail rifle, bail, screwdriver, saw etc.) can both in the process of normal running, survey column and/or electric wire easily and easily.
