[0017] The technical solutions described in this application are schematic diagrams. The following description fully illustrates the specific implementation schemes of this utility model to enable those skilled in the art to practice and reproduce them. The embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] like Figure 1 The diagram shown is a structural schematic of the municipal garden trimmers of this utility model.

[0019] Municipal landscaping trimmers include: shears 1, adjustment box 2, telescopic rod 3, limiting post 4, and limiting plate 5; the adjustment box 2 is a box structure with a handle 21 fixedly connected to the outside, and a first through hole is provided on the top of the adjustment box 2. The two blade handles 11 of the shears 1 are respectively installed in the two first through holes of the adjustment box 2; the bottom of the adjustment box 2 is provided with a second through hole and a limiting plate 5, with the two limiting plates 5 located on both sides of the second through hole, and the limiting plate 5 is provided with a first limiting through hole; the telescopic rod 3 is installed in the second through hole, and the front end of the telescopic rod 3 extends into the adjustment box 2 to connect to the bottom end of the blade handle 11, and the telescopic rod 3 is provided with a second limiting through hole; the limiting post 4 is inserted into the first limiting through hole and the second limiting through hole.

[0020] The surface of the handle 21 of the regulating box 1 is provided with an anti-slip sleeve. The anti-slip sleeve prevents the handle 21 from slipping when gripped.

[0021] like Figure 2 The diagram shown is a schematic representation of the internal structure of the regulating box 2 in this utility model; as shown... Figure 3 The diagram shown is a schematic diagram of the internal structure of the reset magazine 23 in this utility model.

[0022] The regulating box 2 is equipped with a connecting plate 22 and a reset cartridge 23. The bottom of the handle 21 is connected to the top of the connecting plate 22. The inner walls of opposite sides of the regulating box 2 are respectively provided with first guide grooves, and the connecting plate 22 is respectively provided with first guide blocks on both sides. The first guide blocks are installed in the first guide grooves. The front end of the telescopic rod 3 extends into the bottom of the connecting plate 22 of the regulating box 2.

[0023] The connecting plate 22, the first guide block, and the first guide groove can limit the movement direction of the tool handle 11, ensuring that the tool handle 11 can extend or retract smoothly, and making the connecting plate 22 more stable when moving up and down.

[0024] The reset magazine 23 is located inside the regulating box 2. The reset magazine 23 includes: a magazine housing 231, a connecting rod 232, and a reset spring 233. The magazine housing 231 is a box structure. The bottom of the magazine housing 231 is connected to the bottom surface of the regulating box 2. The reset spring 233 is located inside the magazine housing 231 and its bottom is connected to the bottom surface of the magazine housing 231. The top of the magazine housing 231 is provided with a magazine through hole. The connecting rod 232 is installed in the magazine through hole. The top of the connecting rod 232 is connected to the bottom of the connecting plate 22. The reset spring 233 is located at the lower part of the connecting rod 232.

[0025] A reset plate 234 is provided between the reset spring 233 and the connecting rod 232. The top of the reset spring 233 is connected to the bottom of the reset plate 234, and the bottom of the connecting rod 232 is connected to the top of the reset plate 234. Second guide blocks are provided on both sides of the reset plate 234, and second guide grooves are provided on the inner walls of opposite sides of the magazine housing 231. The second guide blocks are installed in the second guide grooves.

[0026] The second guide block and the second guide groove make the reset plate 234 more stable when moving up and down, ensuring that the connecting rod 232 can extend or retract smoothly.

[0027] To enhance the elastic strength of the handle 11 and the telescopic rod 3 when they extend or retract, two reset chambers 23 are provided inside the adjustment box 2, with the two reset chambers 23 located on both sides of the telescopic rod 3.

[0028] The working principle of this utility model is as follows: When it is necessary to prune the green plants at a high place, push the telescopic rod 3. The telescopic rod 3 drives the connecting plate 22 and the handle 11 to move upward. At the same time, the connecting plate 14 pulls the connecting rod 232 to move upward. The return spring 233 extends and the handle 11 extends to a suitable length. The limiting post 4 is inserted into the first limiting through hole and the second limiting through hole to limit the telescopic rod 3 and fix the extension length of the handle 11. Hold the handle 21 and you can operate the scissors 1 to prune the green plants. After trimming, pull out the limiting post 4. The reset spring 233 pulls the reset plate 234 and the connecting rod 232 back. The connecting rod 232 pulls the connecting plate 22 back, and the connecting plate 22 pulls the handle 11 back, thus completing the reset of the handle 11. The telescopic rod 3 extends out from the second through hole. Then, the limiting post 4 is inserted into the first limiting through hole and the second limiting through hole to limit the telescopic rod 3, thereby achieving the effect of resetting the handle 11 and the scissors 1, so that the handle 11 returns to its initial length.

[0029] The terminology used in this invention is descriptive and exemplary, not restrictive. Since this invention can be embodied in various forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
