Easy sampling instrument, includes the first conductive pin and the second conductive pin, the first conductive pin and the second conductive pin are in same level
Side by side, interfixed between the first conductive pin and the second conductive pin by former and later two fixed blocks, the first conductive pin and second is led
The rear end of acusector is connected to signal wire, and the conductive clamp for connecting checker, the first conductive pin are connected with signal wire
Reception head is fixedly connected with the front end of the second conductive pin, reception head underlying photoelectric pulse can be sensed equipped with two by receiving head
The photodiode of signal, the cathode of a photodiode are electrically connected the first conductive pin, and anode is electrically connected the second conductive pin, separately
The cathode of one photodiode is electrically connected the second conductive pin, and anode is electrically connected the first conductive pin, is equipped between two fixed blocks
Contiguous block, the first conductive pin and the second conductive pin are installed on contiguous block, and two are installed with contiguous block in vertical direction
Front and rear draw point side by side, contiguous block is positioned at the upper end of two draw points.

Side, the first conductive pin and the second conductive pin clamp in the bar shaped groove at left and right sides of contiguous block and by contiguous block respectively.
The operation principle of the utility model is：By two draw points being clipped on the shell wall of ammeter bottom case one in front and one in back, gently
Pin contiguous block, one fixed block of front and rear pulling so that receive circuit in two photodiode face ammeter bottom cases on head
Flashlight on plate.Under press or pull up contiguous block, adjust the distance between photodiode and flashlight.By the first conductive pin and
The connected signal wire of second conductive pin connects checker by conductive clamp respectively, since photodiode has polarity, with school
Test device and be connected and have to differentiate between positive and negative anodes, use two photodiodes with opposite polarity while connect the first conductive pin and second
Conductive pin, conductive clamp necessarily have a photodiode job, so conductive clamp is verified in connection when connecting checker
