DETAILED DESCRIPTION

[0022] The present invention is described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

Its only purpose is to give some concepts of one or more aspects in a simplified form as a prelude to a more detailed description that will be given later.

The height of the upper limit block 9 is adjustable, which is used to limit the sliding plate 4 and limit the lifting height of the fixture 10, and a side push cylinder 11 is arranged on the top side wall of one of the sliding plates 4.

[0025] As a specific implementation, there are two upper limit blocks 9, which are symmetrically arranged. Each upper limit block 9 is arranged on the vertical plate 2 through two L-shaped connecting rods 12. The L-shaped connecting rods 12 on each vertical plate 2 are symmetrically arranged. Each L-shaped connecting rod 12 is vertically spaced with a plurality of positioning holes 201, and the outer side surface of the vertical plate 2 is also vertically spaced with a plurality of positioning holes 201.

[0026] Each linear guide rail 3 is provided with a plurality of sliders 13 adapted to and capable of sliding along the linear guide rail. The sliding plate 4 is arranged on the linear guide rail 3 through the sliders 13. When the sliders 13 slide vertically back and forth along the linear guide rail 3, they can drive the sliding plate 4 to move synchronously.

[0027] The side thrust cylinder 11 is arranged on the sliding plate 4 through a positioning seat 14 .
