DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-3 The utility model provides a technical solution: a portable green belt trimmer for urban greening construction, comprising a device seat 1, a rotating ring 2 is vertically rotatably connected to the upper surface of the device seat 1, a top cover 3 is transversely fixedly connected to the top of the rotating ring 2, a plurality of guide rods 4 are vertically fixedly connected to the lower surface of the top cover 3, a circular sliding sheet 5 is transversely slidably connected to the outer surface of the plurality of guide rods 4, a limited block 6 is vertically fixedly connected to the lower surface of the sliding sheet 5, two limiting holes 7 adapted to the limiting block 6 are vertically provided on the upper surface of the device seat 1, a plurality of springs 9 are vertically fixedly connected between the top cover 3 and the sliding sheet 5, a pulling block 8 is vertically fixedly connected to the top of the sliding sheet 5, the top of the pulling block 8 can slidably pass through the top cover 3 and extend upward, an extension handle 10 is transversely fixedly connected to the outer surface of the rotating ring 2, and a grip 11 is fixedly connected to the other end of the extension handle 10;

[0019] The outer side surface of the device seat 1 is laterally provided with a trimming structure.

[0020] The center points of the two limiting holes 7 are located on the same diameter of the sliding sheet 5 .

[0021] The handle of the device is fixedly connected to the outer surface of the rotating ring 2 through an extension handle. When using the device, the handle 11 is rotated to the other side of the trimming structure, and then the device can be used for trimming operations. When the device needs to be folded after trimming is completed, the pulling block 8 is pulled upward to drive the sliding plate 5 to move upward. At this time, the limit block 6 will leave the limit hole 7, and the rotating ring 2 can be rotated to rotate the handle 11 to the same direction of the trimming structure. This method can reduce the overall volume of the device, thereby making the device easy to carry and improving the convenience of the device.

[0022] The sliding plate 5 in the device always moves downward under the action of multiple springs 9, so the multiple limit blocks 6 fixedly connected at the bottom end can always be subjected to downward force so that they can always be located inside the limit hole 7, keeping the position of the rotating ring 2 from rotating easily, thereby ensuring that the handle 11 of the device will not rotate at will during normal use. When people need to rotate the handle 11, pulling the pulling block 8 upward can drive the sliding plate 5 to move synchronously, so that the limit block 6 leaves the limit hole 7. At this time, the limit block 6 no longer restricts the rotating ring 2. At this time, people can rotate the rotating ring 2 at will to change the position of the handle 11. At the same time, during the rotation process, if the limit block 6 moves to the position of another limit hole 7, the limit block 6 can be immediately inserted into the limit hole 7 under the action of the spring 9 to fix the handle 11.

[0023] The trimming knot includes a mounting frame 13 which is fixedly connected to one side surface of the device seat 1 horizontally and has an open end. A first horizontal plate 14 is fixedly connected to the inside of the mounting frame 13 horizontally. The other end of the first horizontal plate 14 is rotatably connected to a second horizontal plate 16 through a hinge. Both ends of the lower surface of the first horizontal plate 14 are vertically rotatably connected to a first chain plate 15. Both ends of the lower surface of the second horizontal plate 16 are vertically rotatably connected to a second chain plate 17. The top ends of the adjacent first chain plates 15 and second chain plates 17 are fixedly connected to a first through shaft 18 and a second through shaft 19, respectively. The first through shaft 18 and the second through shaft 19 are fixedly connected to the top ends of the adjacent first chain plates 15 and second chain plates 17. The through shaft 19 rotatably penetrates the first transverse plate 14 and the second transverse plate 16 and extends upward respectively. The front end of the upper surface of the first transverse plate 14) and the rear end of the upper surface of the second transverse plate 16 are respectively vertically rotatably connected with the first linkage shaft 20 and the second linkage shaft 21. The outer surfaces of the first linkage shaft 20 and the second linkage shaft 21 are fixedly connected with gears 22. The top ends of the two gears 22 are fixedly connected with the first pulley. The outer surfaces of the first through shaft 18 and the second through shaft 19 are fixedly connected with the second pulley. The two first pulleys and the two second pulleys are respectively transmission connected.

[0024] A fixing device 24 is provided between the first transverse plate 14 and the second transverse plate 16. The two first chain plates 15 are connected by a first chain transmission, and the two second chain plates 17 are connected by a second chain transmission. Multiple trimming blades are fixedly connected to the outer surfaces of the first chain and the second chain.

[0025] A pull ring 12 is fixedly connected to the top of the pulling block 8 .

[0026] A motor 23 is fixedly connected to the bottom end of the installation frame 13 , and an output shaft of the motor 23 rotatably passes through the installation frame 13 and is fixedly connected to the bottom end of a first chain plate 15 .

[0027] When the device is in use, the first transverse plate 14 and the second transverse plate 16 will be aligned and connected to form a longer plate-like structure. In this state, the two gears 22 will mesh with each other, and then driven by the motor 23, a first chain plate 15 will be driven to rotate, and another first chain plate 15 will be driven to rotate through the first chain, and then a second pulley will be driven to rotate through the first pulley on the first through shaft 18, so that a gear 22 can be driven to rotate. Since the two gears 22 are meshed with each other, the two second chain plates 17 at the bottom of the second transverse plate 16 will also start to rotate, and the first chain and the second chain will continue to move. The pruning blades arranged on the outer surfaces of the two can trim the green belt. After the trimming is completed, when the device needs to be folded, the second transverse plate 16 can be rotated to reduce the overall volume of the device and improve the convenience of the device.

[0028] The fixing device 24 can fix the first transverse plate 14 and the second transverse plate 16 to prevent problems from occurring during normal operation of the device.

[0029] A pull ring 12 is fixedly connected to the top of the pulling block 8 .

[0030] The pull ring 12 is convenient for people to pull the pull block 8.

[0031] When working, the handle of the device is fixedly connected to the outer surface of the rotating ring 2 through an extension handle. When using the device, the handle 11 is rotated to the other side of the trimming structure, and then the device can be used for trimming operations. When the device needs to be folded after trimming is completed, the pulling block 8 is pulled upward to drive the sliding plate 5 to move upward. At this time, the limit block 6 will leave the limit hole 7, and the rotating ring 2 can be rotated to rotate the handle 11 to the same direction of the trimming structure. This method can reduce the overall volume of the device, thereby making the device easy to carry and improving the convenience of the device.
