The utility model applicant finds that the structure of this type of traditional product has defective work, its structure as shown in Figure 5, mainly be to be provided with a housing 40, the one end is provided with battery portion (among the figure not label), can provide power supply to monitor on the electromagnetic circuit board 50 to the other end, and the outer rim of this circuit board 50 promptly is connected with a survey bar 51, after power switch is opened, can survey 51 pairs of environment on every side of bar by this is monitored, in case measure stronger electromagnetic wave, have then that colored lamp lights and the cry of " gurgling " (this is the design in this circuit board all, with the improved structure-irrelevant of the utility model institute desire, so seldom give unnecessary details), then can remind its position of being surveyed of user that electromagnetic existence is arranged.

Yet above-mentioned traditional structure because structure is not attained perfectly, has following shortcoming on the implementation:

1, because in traditional circuit board, surveying bar is directly to attach the front of being located at circuit board, its test lead curtailment; And place again within the housing, receiving ability is not good enough, so the induction of its test and insensitive, it is not satisfactory therefore to test effect, so the electromagnetic dustiness deficiency of misidentification often is its major defect.

2, because traditional device sensitivity is not good,, generally all need use 9 volts of electric power to use, so on power cost, spend more so its spent electric power is also bigger relatively.

Fundamental purpose of the present utility model provides a kind of architecture advances of electromagenetic wave radiation monitor, it is to be and will members such as intrinsic power supply unit, circuit board and measuring staff to be set in the housing, but be provided with chute: on circuit board, be provided with contact flat spring again at the housing side, this contact flat spring can contact with movable measuring staff, and make the movable measuring staff can be along the chute of housing side and do the action of stretching out and folding, then in use movable measuring staff is stretched out and can be monitored accurately, otherwise, when folding, then has the advantage that it is not taken up room.

Fundamental purpose of the present utility model is achieved in that it mainly is to be provided with power supply unit, circuit board and measuring staff member in housing, it is characterized in that: be provided with chute at least one side of housing; Be provided with contact flat spring again on circuit board, this contact flat spring can touch mutually with movable measuring staff, and makes the movable measuring staff can be along the chute of housing side and do the action of stretching out and folding.

Wherein the openend of chute is provided with the stop section; Movable in addition side lever is provided with lug at its end pin end, when making it pull out certain length, lug just with the stop section card only and locate, make that measuring staff is unlikely to be deviate from.

Wherein side lever can form the shape as n.
