[0002] Landscaping pruning is an important task in garden tree maintenance. Its purpose is to improve the growth of trees, enhance the landscape effect of trees, and ensure the safety of pedestrians and vehicles by pruning branches.

[0003] The equipment used for pruning includes gardening shears for cutting branches and leaves, and electric hedge trimmers for trimming branches and leaves for shaping. During the shearing process, the hedge trimmer trims the leaves by engaging multiple shear teeth. However, due to the multi-tooth structure, the engagement resistance is large during the engagement process, and it is easy to get stuck when it is too close to the leaves, causing mechanical damage.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0028] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically specified.

[0029] The existing multi-tooth structure results in large meshing resistance during the meshing process, which can easily cause the blades to become stuck when too close to the blades, resulting in mechanical damage. To address the above issues, this case proposes the following technical solutions:

[0030] Reference Figures 1 to 4As shown, a garden greening pruning device includes: a body 2, a shell of the body 2 is respectively equipped with a first handle 1 and a second handle 4 for holding the hand body 2, the first handle 1 is retracted and fixedly connected to the body 2, and the second handle 4 is movably connected to the body 2, and a starter 5 is provided on the surface of the first handle 1 for controlling the start of the internal driving component of the body 2, and a cutting part 3 is provided at the front end of the body 2, and the body 2 and the cutting part 3 are mechanically connected. The cutting part 3 includes a support bar 33 and a first shearing rack 34 and a second shearing rack 35, the first shearing rack 34 is fixed in the inner groove of the support bar 33 and is slidably connected to the second shearing rack 35, and the second shearing rack 35 is mechanically connected to the driving component of the body 2, and movable protective bars 32 are respectively installed on both sides of the support bar 33, and the protective bar 32 and the support bar 33 are connected to the adjuster 31 nested in the front end of the body 2, and the adjuster 31 controls the forward and backward movement of the protective bar 32 and the support bar 33.

[0031] The main structure of this device is an organic body 2, and a motor is provided inside the organic body 2 for driving the cutting part 3 at the front end to perform pruning work. The organic body 2 is held by a first handle 1 and a second handle 4. A starter 5 for controlling the organic body 2 is installed on the surface of the first handle 1. Specifically, a motor, a battery and a controller for controlling the motor speed are installed inside the organic body 2. The motor speed is controlled by the starter 5 to better perform the pruning work.

[0032] The structure used for pruning at the front end mainly includes a support bar 33, and a first shearing rack 34 and a second shearing rack 35 are installed inside the support bar 33. The first shearing rack 34 and the second shearing rack 35 cooperate with the motor inside the body 2. Specifically, a cam is used to drive the connecting rod to make one of the first shearing rack 34 or the second shearing rack 35 move back and forth, and the other is fixed, thereby forming a shearing structure to clean the branches and leaves.

[0033] However, if the branches and leaves are relatively thick during the cleaning process, the first shearing rack 34 and the second shearing rack 35 may be in too close contact, causing the roots to be stuck in the gap, resulting in overheating of the machine body 2 during operation.

[0034] The present invention is optimized in this regard, and a protective device is provided on both sides of the first shearing rack 34 and the second shearing rack 35. The protective device is a protective bar 32. The protective bar 32 is divided into two parts, respectively provided on both sides of the support bar 33, and the opening and closing of the protective bar 32 is controlled by the adjuster 31. The specific structure of the protective bar 32 is a first support bar 321 and a second support bar 322. The first support bar 321 and the second support bar 322 are connected to the support bar 33 through a synchronous arm 323. The synchronous arm 323 supports the first support bar 321 and the second support bar 322 to control their movement trajectory. It is controlled by the adjuster 31, and the upper and lower parts of the housing 311 of the adjuster 31 are provided with a driver 312 to drive the swing arm 313 to rotate. During the rotation, the first support bar 321 and the second support bar 322 move outward or inward. When moving outward, the depth of engagement with the root stem is reduced to avoid jamming. Moving inward can be more convenient when trimming some relatively tender branches and leaves.

[0035] There are two drivers 312, which can independently control the first support bar 321 and the second support bar 322 on one side to move independently. When working, one side can be set to protection mode. The state of the protection mode is that either the second support bar 322 or the first support bar 321 moves outward until the first shear rack 34 and the second shear rack 35 are protected inside, which is safer to use.

[0036] The improved device drives the swing arm 313 through the upper and lower drivers 312 of the regulator 31 to protect the first support bar 321 or the second support bar 322 on one side, and controls the depth of the first shear rack 34 and the second shear rack 35 engaging with the plant by extending the first support bar 321 and the second support bar 322, thereby avoiding the plant getting stuck in the gap and causing trouble.

[0037] Furthermore, when the first support bar 321 and the second support bar 322 are fully unfolded, they can be conveniently stored during daily use, thereby preventing the first shearing rack 34 and the second shearing rack 35 from causing damage.

[0038] The above only describes the basic principles and preferred implementations of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the scope of protection of the present invention.

[0039] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
