Alternatively, the vertical bar 4 and the transverse bar 5 of the L-shaped bracket 1 are welded or integrally formed.

Preferably, the first insertion hole is a threaded hole, and the rack bar 3 is provided with an external thread matched with the internal thread of the first insertion hole, so that the rack bar 3 can advance by turning a knob.

Preferably, the limiting device 6 comprises a positioning pin 61 mounted on the support plate 2, and the axis of the positioning pin 61 is consistent with the axis of the rack bar 3;

a second jack is arranged on the supporting plate 2, and a first positioning device 51 is arranged in the second jack; the first positioning device 51 comprises a positioning key 511, a key groove 512 is formed in the transverse rod 5, the first positioning device 51 can be inserted into the key groove 512 in a matching mode, and after the position of the support plate 2 is fixed, the positioning key 511 is inserted into the key groove 512 for positioning, so that the support plate 2 is prevented from moving in the vertical direction; the purpose of controlling the size from the initial position of the toothed bar 3 to the extension length is achieved;

as an option, the second insertion hole is a threaded hole, the positioning key 511 includes a screw plug 5111, a steel ball 5112 and a spring 5113, the steel ball 5112 and the screw plug 5111 are respectively arranged at two ends of the spring 5113, and when the screw plug 5111 is turned with the internal thread of the second insertion hole, the spring 5113 deforms and pushes the steel ball 5112 upwards to be inserted into the key groove 512, so that positioning is achieved;
