The vibration detector comprises a first supporting rod, a second supporting rod and a vibration detector body, wherein the upper end of the first supporting rod is provided with a clamping hole; the second supporting rod is arranged inside theclamping hole; the first supporting rod is provided with a vibration detector length adjusting device; the upper end of the second supporting rod is fixedly connected with a rubber pad; the upper endof the rubber pad is provided with a circular groove; the inner bottom surface of the circular groove is fixedly connected with a first spring; and the upper end of the first spring is fixedly connected with a connecting rope. The vibration detector capable of adjusting the length of the detection head has the advantages that the adjusting steps are simple and easy to operate, thereby reducing thetime waste caused by the length adjustment of the operator; and the length deviation caused by the vibration of the object after the length adjustment is avoided, thereby avoiding the deviation of the detection effect, and ensuring that the vibration detector can perform normal detection.
