Formed with groove is picked and placeed, one of them side for picking and placeing groove is provided with brightness regulating switch for side, and the brightness regulating switch is gear
Toggle switch, the toggle switch adjust the electric current that the electroconductive elastic sheet is powered to copper-foil conducting electricity.
Wherein, fixed pivot is gone back on the base, laminating arms, the front end alignment of the laminating arms are provided with the fulcrum
The detect tank is simultaneously provided with resetting apparatus formed with the rear end with the matched convex block of the detect tank, the laminating arms, described
Resetting apparatus drives the rear end of the laminating arms to push when the laminating arms influence from external force, so that front end is away from the inspection
Survey groove.
Wherein, the resetting apparatus is the magnet for being arranged at laminating arms end.
Wherein, the resetting apparatus is spring, and one end of the spring is connected with base, the rear end of the other end and laminating arms
Connection.
Wherein, the corner of the fixing groove is provided with anticollision chamfering.
The beneficial effects of the utility model：The gauge of the utility model in the both sides of fixing groove formed with picking and placeing groove, wherein
One side for picking and placeing groove is provided with brightness regulating switch, and the brightness regulating switch is gear toggle switch, described to stir out
Close and adjust the electric current that the electroconductive elastic sheet power to copper-foil conducting electricity, during detection, one hand of worker operates laminating arms, in addition a hand
Backlight is picked and placeed, when he thinks that detection brightness is improper, it is only necessary to smoothly stir toggle switch when backlight is picked and placeed
, brightness can be easily adjusted in the case where not influencing detection efficiency, prevents from detecting for a long time and causing visual fatigue
Backlight detection gauge.
