Scissors Mechanism

Attempted using 1 motor to link up two motions but failed.

We will try to operate using two motors.

Arduino testing

Code:
#include <Servo.h>
Servo myservo;

boolean switchValue1;
boolean switchValue2;
boolean switchValue3;

void setup() {
  pinMode(3, INPUT);
  pinMode(5, INPUT);
  pinMode(7, INPUT);
  myservo.attach(9);
}

void loop() {
  switchValue1 = digitalRead(3);
  switchValue2 = digitalRead(5);
  switchValue3 = digitalRead(7);

  if(switchValue1==LOW && switchValue2==LOW && switchValue3==LOW) {
    myservo.write(0);
  }
  else if(switchValue1==HIGH && switchValue2==LOW && switchValue3==LOW) {
    myservo.write(60);
  }
  else if(switchValue1==HIGH && switchValue2==HIGH && switchValue3==LOW) {
    myservo.write(120);
  }
  else if(switchValue1==HIGH && switchValue2==HIGH && switchValue3==HIGH) {
    myservo.write(179);
