Adjusting mechanism, lens module and detection equipment

The invention provides an adjusting mechanism, a lens module and detection equipment. The adjusting mechanism is used for fixing an adjusted part and comprises a mounting part, a fixing part and a buffering part. The mounting part is provided with an accommodating cavity which is used for accommodating an adjusted part; the fixing part can be movably mounted on the side wall of the mounting part; and at least part of the buffering part extends into the side wall of the mounting part, and the two ends of the buffering part abut against the fixing part and the adjusted part respectively. According to the adjusting mechanism, the lens module and the detection equipment, the fixing part can be movably mounted on the side wall of the mounting part, and after the fixing part is adjusted to the position far away from the adjusted part and the position of the adjusted part is adjusted, the fixing part is tightened and pushes the buffering part to abut against the adjusted part, the fixing part can be prevented from b
