[0036] The threaded sleeve 401 is threadedly connected to the outer side of the lifting sleeve 103, and the bottom of the threaded sleeve 401 is formed with a tapered inner groove.

[0037] The threaded sleeve 401 is screwed downward to press and shrink the plurality of fan-shaped taper blocks 104 through the tapered inner groove, so as to realize the close fit of the fan-shaped taper blocks 104 and the outer wall of the T-shaped column 102, thereby realizing the relative position fixation of the lifting sleeve 103 and the T-shaped column 102.

[0038] The angle locking unit comprises a rotating connecting block 402, a connecting piece 403, an inverted U-shaped frame 404, a locking tooth block 405, and a fixed gear 406.
