Problems solved by technology

[0004] The above invention fixes the detection platform through the lock nut through the fixed part. Therefore, if it is necessary to detect other parts of the component to be detected during the detection process, the lock nut needs to be disassembled and then the angle of the adjustment device is used. The lock nut is used to fix it. This method is not only very cumbersome to operate, but also makes it difficult for the operator to grasp the angle of rotation, especially when testing components in a semi-enclosed narrow testing space, it is difficult for the operator to pass through the eyes. The rotation angle of the sensor is observed, thus increasing the difficulty of adjusting the device and affecting the accuracy of the detection data
