[0033] See also Fig. 9 and Fig.10, a mounting frame X3a is provided on the machine body 3, a mounting wheel 3b is rotatably mounted on the mounting frame X3a, and a chain knife 4 is wound around the mounting wheel 3b; it also includes: a mounting frame Y17, a mounting frame Y17 is fixedly mounted between the machine body 3 and the mounting frame X3a; a cleaning wheel 18, a cleaning wheel 18 is rotatably mounted on the mounting frame Y17, the bristles on the cleaning wheel 18 are arranged in a spiral line shape, and the cleaning wheel 18 rotates to clean the hedge debris generated by pruning; a bevel gear 19, a bevel gear 19 is rotatably mounted on both the mounting wheel 3b and the mounting frame Y17, and the two bevel gears 19 are meshed with each other; a synchronous member 20, a synchronous member 20 is installed between the bevel gear 19 on the mounting frame Y17 and the cleaning wheel 18, specifically, in this embodiment, the synchronous member 20 is a combination of a synchronous wheel and a synchronous belt, two synchronous wheels are provided, which are coaxially fixed with the bevel gear 19 on the mounting frame Y17 and the cleaning wheel 18, and the synchronous belt is wound between the two synchronous wheels.

[0034] When using the trimmer for green trimming, first, rotate the fixing member X9, slide the mounting seat X2 according to the height of the hedge trimming, change the height of the machine body 3 and the chain knife 4, and after completion, reverse the position of the fixing member X9 to fix the mounting seat X2. Similarly, rotate the fixing member Y14 to change the height of the waist buckle device 7 according to the height of the operator's waist, and after completion, reverse the position of the fixing member Y14 to fix the mounting seat Y6; then rotate the screw 16 to change the position of the cushion 15 relative to the waist ring 7a or the opening arm 7b, so that when the waist buckle device 7 is worn on the operator's waist, the cushion 15 can fit tightly with the operator's waist, so that the waist buckle device 7 can be stably fixed on the operator's waist;

[0035] After that, slide the buckle 7c to separate the buckle 7c from the waist ring 7a, the elastic member Y13 is compressed, rotate the opening arm 7b, open the gap of the waist ring 7a, so that the operator's waist can pass into the waist ring 7a, and then rotate the opening arm 7b back, the elastic member Y13 cooperates with the buckle 7c to fix the waist ring 7a and the opening arm 7b, so that the waist buckle device 7 is fixed to the operator's waist, and the soft pad 15 makes the operator's waist more comfortable;

[0036] Then, the machine body 3 is started to control the chain knife 4 to rotate at a high speed, and the operator moves horizontally to control the chain knife 4 to trim the hedge laterally. At the same time, the operator uses the handle 8 to stably control the support wheel 5 to support the movement of the trimmer. During the whole process, the weight of the trimmer is on the support wheel 5, which makes the trimmer easy to use and reduces operator fatigue.

[0037] During use, the operator controls the position angle of the machine body 3 and the chain knife 4 by applying force with the waist, and controls the position angle of the support wheel 5 by applying force with the hands, so that the upper bracket 1a and the lower bracket 1b can rotate relative to each other, making the control of the trimmer more flexible, avoiding excessive integration of the control of the movement function and the trimming function of the trimmer, thereby reducing the inconvenience of use caused by the trimmer being too rigid; and the waist buckle device 7 can slide relative to the slide rail 6a, so that the operator's waist can rotate relative to the trimmer, so that the operator can properly adjust his own position without affecting the trimming of the trimmer, and the operator does not have to force himself to maintain an angle, thereby improving the comfort and flexibility of use of the trimmer;

[0038] During use, the rotation of the chain knife 4 will drive the mounting wheel 3b to rotate, and the rotation of the mounting wheel 3b will drive the cleaning wheel 18 to rotate through the bevel gear 19 and the synchronous member 20, so as to clean up the hedge debris generated after hedge pruning. The spiral direction of the cleaning wheel 18 causes the hedge debris to be cleaned to the side of the hedge, which is convenient for the subsequent unified cleaning and collection of the hedge debris, thereby streamlining the cleaning steps and providing convenience for the pruning process.

[0039] When the hedge needs to be trimmed vertically, the sliding block 11 is slid to disengage the buckle 12 from the L-shaped seat 10 and the vertical plate 2b, and the elastic member X7d is compressed to release the fixation of the L-shaped seat 10. At this time, the L-shaped seat 10 is rotated 90 degrees to make the other L-shaped side of the L-shaped seat 10 contact the mounting seat X2, and the direction of the chain knife 4 is downward. After completion, the sliding block 11 is slid, and the buckle 12 is inserted between the L-shaped seat 10 and the vertical plate 2b. The buckle 12 fixes the other L-shaped side of the L-shaped seat 10, and the elastic member X7d applies force to prevent the buckle 12 from disengaging. At this time, the machine body 3 is started, and the chain knife 4 can be controlled to vertically trim the hedge.

[0040] The examples of this specific implementation are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. The same components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
