the fixed gear (54) is arranged inside the first push button (58) and is tightly sleeved on the first connecting shaft (53) through a fixed key (55);
one end of the connecting rod sleeve shaft (56) extends into the adjusting mechanism shell (57) and is fixedly connected with the adjusting mechanism shell (57), and the other end of the connecting rod sleeve shaft (56) is fixedly connected with a connecting rod sleeve shaft sleeve (59) sleeved outside the connecting rod sleeve shaft (56);
one end of the first pressing button (58) extends to the outside of the adjusting mechanism shell (57), and the other end of the first pressing button (58) is in sliding fit with a second connecting shaft (51) which is fixedly connected to the connecting rod sleeve shaft (56);
the supporting spring (52) is arranged between the connecting rod sleeve shaft (56) and the first pressing button (58) and sleeved on the second connecting shaft (51);
a fixed gear structure matched with the fixed gear (54) is arranged inside the first press button (58);
when the first pressing button (58) is pressed, the first pressing button (58) compresses the supporting spring (52), so that the bottom of the first pressing button (58) and a tooth structure which is naturally meshed with the fixed gear (54) are separated from the meshed state, and at the moment, the traction rod (30) and the first adjusting mechanism (40) can drive the first connecting shaft (53) and the fixed gear (54) to rotate around the first connecting shaft (53) in the radial direction;
a limiting table (41) is arranged at the free end part of the first adjusting mechanism (40);
a stepped raised head through hole (421) is formed in the supporting raised head (42);
when the first adjusting mechanism (40) moves close to the mounting hole (32) along the axial direction, the traction rod (30) can rotate around the second connecting part (33) until the limiting table (41) is matched and mounted in the raised head through hole (421), and at the moment, the raised head through hole (421) limits and blocks the limiting table (41);
the clamping part (20) comprises a first clamping piece (21) and a second clamping piece (22);
the first clamping piece (21) is an adjustable clamping assembly and can fix the supporting rod (10) through an elastic bolt (23);
the second clamping piece (22) fixes the clamping part (20) at the use position through the second clamping piece (22);
a supporting rod hole (211) matched with the supporting rod (10) is formed in the first clamping piece (21);
a fixing groove (221) is formed in the second clamping piece (22);
the support rod (10) adopts a straight rod or a bent rod.
