The end of the contact rod 321 pushes the isosceles trapezoidal block 323 to slide in the horizontal groove 313 and compress the second spring 322. The isosceles trapezoidal block 323 pushes the two right trapezoidal blocks 324 to slide in the horizontal groove 313 in a direction away from each other. The right trapezoidal block 324 pushes the push rod 325 to move. The inclined surface at the end of the push rod 325 fits and slides with the spherical surface at the bottom of the fixed slider 327, thereby driving the fixed slider 327 to slide upward in the inclined groove 314. The tops of the two fixed sliders 327 extend out of the inclined groove 314 to clamp and fix the ends of the camshaft 4, thus realizing the fixation of the camshaft.

[0038] When the present utility model is in use, start the vibration sand cleaning equipment main body 1. The vibration end of the vibration sand cleaning equipment main body 1 contacts the camshaft 4 and drives the camshaft 4 to vibrate. The buffer is realized during vibration sand cleaning by the upper buffer plate 222 sliding on the sliding rod 223 and buffering through the first spring 224.
