Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description of the principles of the invention is provided in connection with the accompanying drawings.

The tool for adjusting the height of the vibration groove, which is designed by the invention, comprises a circular disc body 1, a top cover 3, a screw shaft 2 and a shaft sleeve 4, wherein the shaft sleeve 4 is coaxially connected with the circular disc body 1, the shaft sleeve 4 does rotation without radial movement relative to the circular disc body 1, and a rotation fixing mechanism which is in contact with the circular disc body 1 is further arranged inside the circular disc body 1. One end of the screw shaft 2 is inserted into the shaft sleeve 4, the inner surface of the shaft sleeve 4 and the surface of the screw shaft 2 are provided with mutually matched threads, and the length of the thread structure is greater than the height required to be adjusted by the groove body. The other end of the screw shaft 2 is vertically connected with the top cover 3, and the screw shaft 2 is pushed to linearly move along the radial length direction by the rotation of the shaft sleeve 4.

One end of the shaft sleeve 4 is positioned in the disc body 1, and the other end of the shaft sleeve is positioned outside the disc body 1. One end of the shaft sleeve 4, which is positioned at the outer side of the disc body 1, is provided with a square head for inserting a wrench.
