Detailed Description
In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.
As shown in fig. 1-5, the present invention comprises: the adjusting part comprises an adjusting part body 1, an outer sleeve 2 and an inner sleeve 3, wherein a groove 4 is formed in the adjusting part body 1, the inner sleeve 3 is sleeved in the groove 4, the outer sleeve 2 is arranged on the inner sleeve 3, and the outer sleeve 2 is clamped on the adjusting part body 1;
the outer sleeve 2 and the inner sleeve 3 are coaxially arranged up and down, the inner sleeve 3 comprises a base 31 and a cylindrical protrusion 32 integrally arranged on the base 31, the outer sleeve 2 comprises a top cover 21 and an annular column 22, the annular column 22 is clamped on the inner wall of the groove 4, the annular column 22 is sleeved on the outer wall of the cylindrical protrusion 32, and a gap is formed between the annular column 22 and the base 31;
the outer sleeve 2 and the inner sleeve 3 are provided with unthreaded holes 5 which are communicated up and down.
In use, the upper surface and the panel beating contact of outer tube 2, the screw from the top down of outer tube 2 and interior sleeve pipe 3 and wear into, outer tube 2 and interior sleeve pipe 3's design play the support and thick spacing effect of screw, and use self-tapping screw after, plastic materials's structure carries out the rubber coating to the screw, prevents that it from sliding back and forth at will.
