Referring to Figures 1 to 7, a clamping mechanism of a tree whitening machine includes a T-shaped connecting rod 1-5, a first clamping hand 1-2, a second clamping hand 1-1 and an automatic front and rear telescopic brush The middle part of the T-shaped connecting rod 1-5 has a chute 1-5-1, and the chute 1-5-1 is covered with a connecting pin that can slide along the chute, and the connecting pin is hinged Left and right long rods 1-3, the ends of the left and right long rods 1-3 are hinged with the first clamping hand 1-2, and the ends of the T-shaped connecting rod 1-5 are respectively connected with the left and right The short rod 1-4 is hinged, and the ends of the left and right short rods 1-4 are hinged with the second clamping hand 1-1, and the ends of the second clamping hand 1-1 are hinged with the first clamping hand. The middle part of the handle 1-2 is hinged, and the automatic front and rear telescopic brush group includes four groups of automatic front and rear telescopic brushes 2-1 and two groups of automatic front and rear telescopic rotating brushes 2-2, and the automatic front and rear telescopic brushes 2- 1 is installed on the first telescopic device, and the first telescopic device is fixedly installed on the second clamping hand 1-1, and the automatic telescopic rotating brush 2-2 is installed on the second On the retractor, the second retractor is fixedly installed on the first clamping hand 1-2.

The first holding hands 1-2 are two S-shaped holding hands, and the second holding hands 1-1 are folded holding hands. The upper end of the T-shaped connecting rod 1-5 is connected with a reset mechanism, and the reset mechanism is a spring. Both the first retractor and the second retractor are tertiary slide rails 2-5 and springs 2-7, the upper slide rails of the three-stage slide rails are fixed on the clamping hands by grub bolts, and the three-stage slide rails The lower rail of the lower rail passes through a flat-head bolt, and the other end of the flat-head bolt fixes the brush, and the spring is installed between the front flat-head nut and the upper slide rail.

The clamping hand 1 adapted to the change of the diameter is composed of the brush group 2 which can automatically stretch back and forth. When the utility model starts to work, it enters the normal working state from the resting state in Fig. 3, and the long rod connecting piece 1-3 is set in the chute 1-5-1 of the T-shaped connecting rod 1-5 and moves backward first. , this movement makes the secondary gripper composed of S-shaped gripper accessories 1-2 open first; when it moves to the bottom, it drives the T-shaped connecting rod 1-5 to move backward together, and the T-shaped connecting rod 1-5 drives The movement of the short rod connecting piece 1-4 makes the first-level clamping hand composed of 120-degree clamping hand fittings 1-1 open.
