Taper detection device convenient to adjust

The utility model discloses a taper detection device convenient to adjust, which comprises a substrate, a motor is mounted in the middle of the lower surface of the substrate, a rotating groove is formed in the middle of the upper surface of the substrate, and a placing plate is rotatably mounted in the rotating groove. According to the conicity detection device convenient to adjust, a workpiece placed on the surface of the placing plate is rapidly fixed and clamped through the limiting mechanism, so that the conicity detection device convenient to adjust can be suitable for detection work of workpieces of different sizes; the distance between the two distance measuring laser transmitting ends can be rapidly detected through cooperative use of the distance measuring laser transmitting ends and the transverse shaft distance measuring laser receiving ends which are installed on the outer side walls of the side plates correspondingly, diameter detection of a workpiece is completed, the top plate can make contact
