DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-5 The utility model provides an embodiment: a greening maintenance device for municipal engineering, comprising:

[0027] The handle assembly 1 includes two groups of handle assemblies 1, one group of handle assemblies 1 has a connecting end connected to a first connecting member 2, and the other group of handle assemblies 1 has a connecting end connected to a second connecting member 3;

[0028] A first blade 4, the first blade 4 is fixedly connected to the first connecting member 2 via a first bolt 6;

[0029] A second blade 5, the second blade 5 is fixedly connected to the second connecting member 3 via a first bolt 6;

[0030] The second bolt 7 passes through the first blade 4 and the second blade 5, and the first blade 4 and the second blade 5 are rotatably connected with the second bolt 7 as an axis.

[0031] Furthermore, the handle assembly 1 includes a connecting head 11, one end of which is fixedly connected to an inner cylinder 12, the other end of which is fixedly connected to a positioning seat 15, and a handle rod 13 is sleeved on the outside of the inner cylinder 12. By sliding the inner cylinder 12 and then the handle rod 13, the connection length of the handle rod 13 and the inner cylinder 12 can be adjusted, thereby increasing the use length of the device and increasing its trimming range, so that the device can flexibly adjust its length according to the place of use.

[0032] Furthermore, the first connecting member 2 and the second connecting member 3 have the same structure at one end near the positioning seat 15. A limiting plug-in 21 is provided at one end of the first connecting member 2 near the positioning seat 15. A positioning groove adapted to the limiting plug-in 21 is opened at the center of the positioning seat 15, and the limiting plug-in 21 is plugged into the inside of the positioning groove. The plug-in connection between the limiting plug-in 21 and the positioning seat 15 plays a good limiting role, thereby ensuring the stability of the connection of the first connecting member 2. The plug-in positioning effectively avoids rotation of the connection point of the first connecting member 2.

[0033] Furthermore, a positioning rivet 8 is riveted through the positioning seat 15 and the limiting plug-in 21, and the handle rod 13 is slidably connected to the inner cylinder 12. The sliding connection between the inner cylinder 12 and the handle rod 13 facilitates the adjustment of its use length. A threaded hole is provided on the outer wall of the handle rod 13 at one end close to the connecting head 11, and a screw 14 is connected to the internal thread of the threaded hole. The screw 14 abuts against the outer wall of the inner cylinder 12. Through the threaded connection of the screw 14, after the length of the inner cylinder 12 and the handle rod 13 is adjusted, the inner cylinder 12 can be squeezed by turning the knob of the screw 14, thereby ensuring the stability of the inner cylinder 12 and the handle rod 13 after adjustment.

[0034] Furthermore, an anti-slip handle is provided at one end of the screw 14 away from the inner tube 12. The setting of the anti-slip handle makes it convenient to twist the screw 14, thereby completing the drive control of the screw 14. The outer wall of the handle rod 13 is provided with anti-slip bumps. The setting of the anti-slip bumps can increase the friction between the device and the hand, thereby improving its hand-holding stability, thereby ensuring the stability of the device when in use and effectively reducing the occurrence of hand slippage.

[0035] Furthermore, the first connecting member 2 and the second connecting member 3 are both step-shaped, and an outer wall of one side of the first blade 4 and an outer wall of one side of the second blade 5 fit together. The fit between the blades can ensure the shearing effect.

[0036] Working principle: The first blade 4 and the second blade 5 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, the use length of the handle assembly 1 is adjusted according to the influence of factors such as the pruning position. First, the screw 14 is loosened, and the sliding adjustment of the inner cylinder 12 and the handle rod 13 can be further achieved. After adjusting to the appropriate length, the inner cylinder 12 is squeezed and fixed by the knob of the screw 14, and then the shearing process of the device can be achieved by holding the handle rod 13, which is used for maintenance and pruning operations of greening.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
