[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model embodiment discloses a pruning device for municipal greening. Figure 1-5 , a pruning device for municipal greening, comprising a hedge trimmer body 1, a pruning tool 2 and a housing 3 are arranged on one side of the hedge trimmer body 1, and the housing 3 is located at the upper end of the pruning tool 2, a protection mechanism 4 is arranged on one side of the housing 3 for safety protection of the pruning tool 2, and an adjustment mechanism 5 is arranged inside the protection mechanism 4 for adjusting the use angle of the protection mechanism 4;

[0030] Reference Figure 3 The protection mechanism 4 includes a main protection plate 401, two rotating rods 402 and two side protection plates 403. The main protection plate 401 is arranged on the side of the shell 3 away from the hedge trimmer body 1. The two rotating rods 402 are respectively rotatably arranged on the front and rear sides of the main protection plate 401. The two side protection plates 403 are respectively arranged on the corresponding rotating rods 402, and can cooperate with the main protection plate 401 to effectively protect the pruning tool 2.

[0031] By adopting the above technical solution, the main protective plate 401 and the rotating rod 402 make it difficult for the staff to touch the pruning tool 2 during carrying, and the risk of the pruning tool 2 colliding with external objects is reduced. At the same time, the branches and leaves will not splash onto the arms of the staff during pruning, so that the staff can prune the tree crown more comfortably.

[0032] Reference Figure 4The adjusting mechanism 5 includes two connecting shafts 501, two worm wheels 502, a worm 503 and two rotating disks 504. The two connecting shafts 501 are both rotatably arranged inside the housing 3. One end of the rotating rod 402 penetrates into the interior of the housing 3 and is connected to the connecting shaft 501. The two worm wheels 502 are respectively arranged on the outside of the corresponding connecting shafts 501. The worm 503 is rotatably arranged inside the housing 3, and the worm 503 is meshed with the worm wheel 502 to drive the worm wheel 502 to rotate. The rotating disk 504 is rotatably arranged at the upper end of the housing 3. The bottom end of the rotating disk 504 is connected to the top end of the worm 503 to drive the worm 503 to rotate.

[0033] By adopting the above technical solution, the staff can rotate the turntable 504 to drive the rotating rod 402 to rotate, and the rotation of the rotating rod 402 can drive the side protection plate 403 to rotate upward. At this time, the staff can trim the tree crown through the pruning tool 2.

[0034] Reference Figure 1 , Figure 2 and Figure 5 A main handle 6 and a front handle 7 are respectively arranged on the outside of the hedge trimmer body 1 for conveniently holding the hedge trimmer body 1 during pruning work, and a rubber sleeve 8 is arranged on the outside of the front handle 7.

[0035] By adopting the above technical solution, when pruning the tree crown, the worker holds the main handle 6 and the front handle 7 with two arms respectively, making it convenient to take the hedge trimmer body 1.

[0036] Reference Figure 2 The main protective plate 401 and the side protective plate 403 are both made of transparent material, the trimming tool 2 is located on the inner side of the two side protective plates 403, and the bottom end of the side protective plate 403 is lower than the bottom end of the trimming tool 2.

[0037] By adopting the above technical solution, the main protective plate 401 and the side protective plate 403 are both made of transparent materials, so that during the process of pruning the tree crown, the staff can easily check the pruning situation.

[0038] Working principle: When the utility model is in use, when pruning the tree crown, the staff can rotate the turntable 504 to drive the worm 503 to rotate, and the rotation of the worm 503 can drive the two worm wheels 502 to rotate in the opposite direction. The rotation of the worm wheel 502 drives the connecting shaft 501 to rotate, and the rotation of the connecting shaft 501 can drive the rotating rod 402 to rotate, and the rotation of the rotating rod 402 can drive the side protection plate 403 to rotate upward. At this time, the staff can prune the tree crown through the pruning tool 2, and the main protection plate 401 and the side protection plate 403 are used to prevent the branches and leaves from splashing onto the staff's arms during pruning, making it more comfortable for the staff to prune the tree crown. When the pruning is completed, the side protection plate 403 is rotated to the initial position. At this time, the pruning tool 2 can be effectively surrounded and protected by the main protection plate 401 and the side protection plate 403, so that the staff is not easy to contact the pruning tool 2 during carrying the pruning tool 2, and the risk of the pruning tool 2 colliding with external objects is also reduced.

[0039] When the utility model is in use, the main protective plate 401 and the rotating rod 402 make it difficult for the staff to touch the pruning tool 2 during the carrying process, and the risk of the pruning tool 2 colliding with external objects is also reduced. At the same time, the splashing branches and leaves can be blocked during the tree crown pruning process, which greatly improves the comfort of the staff when pruning the tree crown.
