Transformer coil connection insulator installation detection device

The utility model discloses an installation detection device for a transformer coil connection insulator, which is applied to the field of insulator detection and comprises an ultrasonic flaw detector body, and a connection ring is installed on one side of the ultrasonic flaw detector body. According to the ultrasonic flaw detector, the pin is connected with the staff clothes of a detector, when the ultrasonic flaw detector body slips out of the hand in the detection process, the pin pulls the connecting rope, the connecting rope pulls the fixing ring, the fixing ring pulls the connecting ring, and the connecting ring can pull the ultrasonic flaw detector body, so that the ultrasonic flaw detector body is prevented from falling off; the fixing frame is connected with the detection probe, the fixing frame is connected with the ball head, and the ball head capable of rotating in the connecting seat is arranged, so that during use, the detection end of the detection probe can be toppled over due to the dead weig
