[0029] By setting the above structure, the servo motor 22 is powered by the rechargeable power supply 14, and the servo motor 22 drives the lead screw A21 to rotate continuously, and the lead screw A21 drives the sliding frame 23 guided by the inner wall of the U-shaped frame 12 to move right continuously, and the sliding frame 23 drives the rack A24 to move right synchronously, and the two racks A24 move close to the two gears B42, and the sliding frame 23 drives the rack B27 to move right through the elastic connecting piece 26, and in this process, the limiting column 29 moves left relative to the inside of the limiting sliding groove 28, and after the subsequent fertilizer application is completed, the fertilizer pump 15 is powered off, and the rechargeable power supply 14 is powered on for the servo motor 22, and the servo motor 22 drives the lead screw A21 to rotate reversely, and the lead screw A21 drives the sliding frame 23 guided by the inner wall of the U-shaped frame 12 to move left to reset, and the sliding frame 23 drives the rack A24 to move left synchronously, and the stretched elastic connecting piece 26 gradually recovers.

[0030] As shown in Figure 4 Any one set of adjustable locking mechanism 3 includes a rotating shaft 31 rotatably nested in the inside left end of the U-shaped frame 12, a gear A32 fixedly sleeved on the outside bottom of the rotating shaft 31, an arc-shaped arm 33 fixedly connected on the outside of the gear A32, an aluminum alloy profile integrally formed, light in weight and rigid enough, arc-shaped design fitting the tree profile, adapting to the locking needs of trees with different chest diameters, two adjusting screws 34 slidingly penetrating the outside of the arc-shaped arm 33, a locking pressing plate 35 fixedly connected on the inside end of the adjusting screw 34, made of ABS engineering plastic, tough in texture and not damaging the tree bark, not causing scratches when contacting the tree, protecting the skin integrity during tree maintenance, a non-slip pad 36 adhesively fixed on the inside of the locking pressing plate 35, made of food-grade silicone, large friction coefficient and good non-slip effect, enhancing the adhesion of the locking pressing plate 35 to the surface of the tree, avoiding sliding, and the silicone is soft and elastic, adapting to the slight concave-convex surface of the tree, and two locking nuts 37 are sleeved on the outside of the adjusting screw 34, clamping and fixing the arc-shaped arm 33.

[0031] By setting up the above structure, during the rightward movement of rack B27, the two gears A32 drive the two opposing arc arms 33 to rotate relative to each other around the adjacent rotating shaft 31. When the rotating shaft 31 rotates, the adjusting screw 34 drives the locking plate 35 to rotate synchronously, thereby causing the locking plate 35 to move the anti-slip pad 36 closer to the tree to be maintained. At the same time, the rotating shaft 31 also drives multiple hollow rods 46 to move closer to the tree to be maintained. When the limiting post 29 moves to the leftmost end of the inner side of the limiting groove 28, the two arc arms 33 close together. At this time, the four locking plates 35 are pressed against the surface of the tree to be maintained by the four anti-slip pads 36, thus forming a lock. At this time, due to the limitation of the limiting post 29 on the limiting groove 28, rack B27 cannot continue to move to the right. Subsequently, as the sliding frame 23 continues to move to the right, the elastic connector 26 connecting the sliding frame 23 and rack B27 is gradually stretched.

[0032] When locking trees with larger diameters, the inner locking nut 37 is adjusted towards the adjacent locking plate 35, and then the outer locking nut 37 is also adjusted towards the adjacent locking plate 35. At this time, the adjusting screw 34 drives the locking plate 35 to move outward, thereby increasing the locking capacity of the four locking plates 35. When locking trees with smaller diameters, the outer locking nut 37 is adjusted away from the adjacent locking plate 35, and then the inner locking nut 37 is also adjusted away from the adjacent locking plate 35. At this time, the adjusting screw 34 drives the locking plate 35 to move inward, thereby reducing the locking capacity of the four locking plates 35.
