Synchronization detection device for multiple starters

The invention provides a multi-starter synchronism detection device, which comprises a power supply, a timer, a relay and a starter fixing tool, and is characterized in that the starter fixing tool comprises a bottom plate, a vertical plate and an insulating plate, the vertical plate is provided with a plurality of through holes for starter driving gears to pass through, the insulating plate is parallel to the vertical plate, the insulating plate is provided with limiting columns in one-to-one correspondence with the through holes, and the limiting columns are connected with the timer. The vertical plate and the limiting column are made of metal materials. The number of the timers and the number of the relays are the same as the number of starters to be detected. The anode of the power supply is connected with the anode contacts of the timers and the coil anode contacts of the relays, the cathode contacts of the timers are connected with the normally-closed contacts of the relays, the cathode of the power sup
