[0024] 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 .

[0026] The utility model green belt shrub trimmer comprises a transverse trimming mechanism 1 and two vertical trimming mechanisms 2 respectively arranged on both sides of the transverse trimming mechanism 1, and the spacing between the two vertical trimming mechanisms 2 is adjustable, and the trimming heights of the two vertical trimming mechanisms 2 are also adjustable.

[0027] The green belt shrub trimmer of the utility model can meet the trimming needs of green belts with trimming needs on both the top and the sides by providing a horizontal trimming mechanism 1 and two vertical trimming mechanisms 2. In addition, the spacing between the two vertical trimming mechanisms 2 and the trimming height can be adjusted, so the size requirements of different green belts can be met, and the utility model has strong applicability.

[0028] In one embodiment, see Figure 2-6 The horizontal trimming mechanism 1 includes two first trimming arms 101, and the vertical trimming mechanism 2 includes a slider assembly 201. The slider assembly 201 includes a slider body 2011 that is slidably matched with the two first trimming arms 101 and two plugs 2012 that are respectively inserted into the slider body 2011. Each of the first trimming arms 101 includes a first support arm 1011, and the first support arm 1011 is provided with a plurality of slots 1012 along its length direction for corresponding plugs 2012 to be inserted, and the plugs 2012 can be plugged and matched with any corresponding slot 1012. With this design, the spacing between the two vertical trimming mechanisms 2 can be adjusted by sliding the slider body 2011, and the adjustment can be fixed by plugging and matching the plugs 2012 with the slots 1012. The structure is simple and easy to operate.

[0029] In one embodiment, see Figure 3 , 4 The two plugs 2012 are elastically inserted into the slider body 2011, and the slider assembly 201 further comprises two support rods 2013 respectively arranged at the positions of the slider body 2011 corresponding to the plugs 2012, and a limiting rod 2014 rotatably arranged on the support rod 2013, and a C-shaped buckle 2015 is further arranged at the end of the plug 2012, and the C-shaped buckle 2015 can be snap-fitted with the limiting rod 2014. With such a design, the plug 2012 can be fixed by the snap-fit ​​cooperation between the C-shaped buckle 2015 and the limiting rod 2014, thereby ensuring the stability of the plug 2012. In the present embodiment, the plug 2012 can be set to be in a compressed state when not plugged in, and at this time it is fixed by the limiting rod 2014. After reaching the specified position, the contact is locked and the plug 2012 is automatically inserted. The plug 2012 can also be set to be in a compressed state when plugged in, and after plugging in, it is fixed by the limiting rod 2014 to keep the plug 2012 plugged in stable. In the present embodiment, the elastic insertion of the plug 2012 is achieved by a spring.

[0030] In one embodiment, see Figure 2 , 5The first trimming arm 101 further includes a plurality of first bevel gears 1013 rotatably disposed in the first support arm 1011, a plurality of first trimming heads 1014 connected to the outside of the first support arm 1011 in one-to-one correspondence with the plurality of first bevel gears 1013, a plurality of second bevel gears 1015 disposed in the first support arm 1011 and meshing with the plurality of first bevel gears 1013 in one-to-one correspondence, and a plurality of connecting rod assemblies 102 rotatably disposed in the first support arm 1011 and connecting two adjacent second bevel gears 1015. With this design, the linkage rotation of the plurality of first trimming heads 1014 on a first trimming arm 101 is realized by only providing a driving mechanism to drive one of the second bevel gears 1015 to rotate, and in this embodiment, the specific driving structure can be realized by using a motor and a connecting rod structure with a bevel gear in the prior art, but is not limited thereto.

[0031] In one embodiment, see Figure 6 , 7 The connecting rod assembly 102 includes a telescopic rod 1021 connected to one of the second bevel gears 1015 and elastically sliding along the length direction of the first trimming arm 101, an insert block 1022 connected to the telescopic rod 1021, a receiving block 1023 plug-matched with the insert block 1022, and a receiving rod 1024 connected to the receiving block 1023 and connected to the other second bevel gear 1015, and the insert block 1022 and the receiving block 1023 are plug-matched to form a notch 1025, and the slot 1012 and the notch 1025 are distributed along the same straight line, and the bolt 2012 can be inserted into the notch 1025 to realize the separation of the insert block 1022 from the receiving block 1023. With this design, when the plug 2012 is inserted into the notch 1025, the corresponding plug block 1022 is separated from the receiving block 1023, so that the first trimming head 1014 on the first trimming arm 101 is divided into different parts, so that the first trimming heads 1014 outside the size on both sides of the transverse trimming mechanism 1 after the size adjustment do not rotate, so as to avoid accidental injury or waste of resources;

[0032] In this embodiment, a driving structure in which a motor and a connecting rod structure with a bevel gear are arranged in the middle of the first trimming arm 101 to realize driving is taken as an example. When the two slider bodies 2011 slide into place in the adjustment interval of the two vertical trimming mechanisms 2, the first trimming head 1014 located between the end portion and the two slider bodies 2011 on the first trimming arm 101 does not rotate, and the remaining first trimming heads 1014 still rotate to perform trimming operations;

[0033] In this embodiment, the connecting rod assemblies 102 close to both ends of the first trimming arm 101 can be selected to adopt the above structure, and the connecting rod assembly 102 close to the middle portion only adopts a single rod structure to reduce manufacturing costs.

[0034] In one embodiment, see Figure 6 The plug end of the plug block 1022 is wedge-shaped and tilted downward, and the plug end of the plug 2012 is wedge-shaped to match the plug end of the plug block 1022. This design facilitates the plug 2012 to be inserted into the notch 1025 and push the plug block 1022 out of the receiving block 1023 when inserted.

[0035] In one embodiment, see Figure 3 The vertical trimming mechanism 2 further includes two second trimming arms 203 rotatably connected to the slider assembly 201 and a third trimming arm 204 slidably disposed between the two second trimming arms 203 along the length direction of the second trimming arms 203. This design enables the vertical trimming mechanism 2 to be rotatably adjusted for storage and height adjustment to meet different trimming size requirements;

[0036] In this embodiment, when the vertical trimming mechanism 2 is stored, the second trimming arm 203 and the third trimming arm 204 remain parallel in the horizontal direction and parallel in the vertical direction with the first trimming arm 101, and the blades of the three are opposite.

[0037] In one embodiment, see Figure 3 The second trimming arm 203 and the third trimming arm 204 both include a second support arm 2031 and a plurality of second trimming heads 2032 rotatably disposed on the second support arm 2031. In this embodiment, the specific structures of the second trimming arm 203 and the third trimming arm 204 can be implemented in the same structure as the first trimming arm 101, and the connecting rod assembly 102 in the first trimming arm 101 can be directly used as a connecting rod to reduce the manufacturing cost.
