[0022] The other side of the top surface of support plate 2 is slidably installed with a mounting plate 10, and the mounting plate 10 is installed with two micrometers 11, and the end of the micrometer 11 is a measuring rod.

[0023] The middle part of support plate 2 is provided with a circular groove, and the carousel 7 is rotatably arranged in the circular groove. The motor 15 is fixedly installed in the base 1, and the output end of the motor 15 is fixedly connected with the bottom end of the carousel 7. The motor 15 is a speed reducer, which can slowly rotate the carousel 7 through the output end when it works, thereby slowly rotating the cylindrical roller body 9 in the carousel 7.

[0024] The top surface of the carousel 7 is provided with a groove 16, and the cylindrical roller body 9 is jointed in the groove 16. A plurality of baffles 8 are uniformly fixedly installed on the top surface of the carousel 7 along the circumference. A rubber sleeve is attached to one side of the baffle 8 facing the cylindrical roller body 9, and the baffle 8 is attached to the surface of the cylindrical roller body 9.
