Description

Technical Field

[0001] The utility model belongs to the technical field of greening pruning, and particularly relates to a pruning device for garden greening. Background Technique

[0002] During the growth process of trees, new branches and leaves will continuously grow. For some trees, the bottom branches and leaves must be pruned. If there are too many branches and leaves on the trees, a lot of nutrients will be consumed. By cutting off the excess branches, the consumption can be reduced, which is beneficial to the growth of the tree trunks. In addition, for the sake of beauty and maintenance of some ornamental trees, some branches need to be pruned. As the trees grow, the branches also become larger and larger. It is extremely laborious to prune the branches purely by manpower. It is very difficult to cut off the branches, which cannot meet the work requirements. Moreover, during the shearing process, it is difficult to control the shearing gap, and the manual labor intensity is relatively large.

[0003] For example, the Chinese patent with the publication number CN215223278U discloses an electric shear. It includes an electric shear main body. A fixed seat is provided at the bottom of the electric shear main body. A multi-functional mounting plate is provided inside the electric shear main body. A shearing fixed blade is provided on the multi-functional mounting plate. The shearing fixed blade extends out of the top of the electric shear main body. A movable blade that can rotate along one end close to or away from the shearing fixed blade is provided on the multi-functional mounting plate.

[0004] In this technical solution, during shearing, the movable blade is driven to rotate by an angle-adjustable driving structure, and then shearing is performed through the cooperation between the movable blade and the shearing fixed blade. During the shearing process, the shearing gap can be automatically controlled according to the shearing needs, without manual operation to maintain the shearing state. Especially when shearing relatively hard objects such as tree branches, the shearing driving force is relatively strong, which is applicable to various shearing operations, and the degree of automation is relatively high, greatly reducing the manual labor intensity.

[0005] Since the force arm of this electric shear is fixedly arranged inside, it cannot be used when the battery runs out. In the prior art, to make up for this shortcoming, the force arm is arranged on the outside of the device, and it can still be used after running out of power. However, during the electric use process, the force arm will move actively, and it is easy to slip when holding the force arm of the device. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a pruning device for garden greening aiming at the above existing technical problems, so as to achieve the effect of being convenient to use after switching between electric and manual modes.

[0007] In view of this, the utility model provides a pruning device for landscaping, which includes a fixed force arm and a movable force arm. A hinge shaft is fixedly installed in the middle of the fixed force arm, and the movable force arm is rotatably connected to the outer surface of the hinge shaft. Blades are provided at the tops of both the fixed force arm and the movable force arm. A power mechanism for driving the two blades to approach each other is fixedly installed at one end of the fixed force arm and the movable force arm away from the blades. A power supply for driving the power mechanism to work is provided at the bottom end of the fixed force arm. Limiting plates are fixedly installed at both ends of the hinge shaft. A fixed handle is fixedly installed on one side of the limiting plate located on the movable force arm, and a sliding handle is slidably connected to the side of the fixed handle away from the fixed force arm.

[0008] Preferably, the power mechanism includes an active electromagnet fixedly installed inside the fixed force arm, and a passive electromagnet fixedly installed inside the movable force arm. Both the passive electromagnet and the active electromagnet are powered by the power supply.

[0009] Preferably, the power supply is connected to the passive electromagnet through a wire, and the wire is embedded inside the fixed force arm and the movable force arm. The shape of the wire at the hinge shaft is spiral.

[0010] Preferably, the power mechanism includes a semi-tooth ring concentric with the hinge shaft, and the semi-tooth ring is fixedly connected to the movable force arm. A power gear meshing with the semi-tooth ring is rotatably connected to the middle of the fixed force arm, and a power source for driving the power gear to rotate is fixedly installed on the fixed force arm.

[0011] Preferably, insertion interfaces are provided inside the fixed force arm and the movable force arm, insertion blocks are inserted inside the insertion interfaces, the blades are fixedly connected to the insertion blocks, and the insertion blocks are fixedly connected to the fixed force arm or the movable force arm through bolts.

[0012] Preferably, the bolts include vertical bolts and horizontal bolts. The vertical bolts penetrate through the insertion block from top to bottom, and the horizontal bolts penetrate through the insertion block from front to back.

[0013] Preferably, spring snap joints are embedded at both the upper end and the lower end of one side of the fixed handle, and the spring snap joints are snap-connected to the sliding handle.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. For this pruning device for landscaping, when used electrically, hold the fixed force arm and the sliding handle, and drive the two blades to approach each other through the power mechanism to achieve cutting. Since both the fixed force arm and the fixed handle are fixed, they are not easy to fall off during the holding process. When it is necessary to adjust to manual use, slide the sliding handle upward to expose the movable force arm, and manual cutting can be achieved by manually pressing the movable force arm. Sliding the sliding handle upward does not affect manually pressing the movable force arm, so that the device is convenient to use both after switching between manual and electric modes.

[0016] 2. The pruning device for landscaping has spring snap joints embedded at both the upper and lower ends on one side of the fixed handle. The spring snap joints are snap-connected to the sliding handle, and this arrangement can limit the position of the sliding handle. BRIEF DESCRIPTION OF THE DRAWINGS

Blades 4 are provided at the tops of both the fixed force arm 1 and the movable force arm 2. A power mechanism 6 for driving the two blades 4 to approach each other is fixedly installed at one end of the fixed force arm 1 and the movable force arm 2 away from the blade 4. It also includes a control mechanism in the prior art, and the adjustment of the electric control part of the device is realized through the control mechanism. A power supply 9 for driving the power mechanism 6 to work is provided at the bottom end of the fixed force arm 1. Limit plates 5 are fixedly installed at both ends of the hinge shaft 3. A fixed handle 7 is fixedly installed on one side of the limit plate 5 located on the side of the movable force arm 2. A sliding handle 8 is slidably connected to the side of the fixed handle 7 away from the fixed force arm 1.

[0027] Based on the above structure,

[0028] In one embodiment, the power mechanism 6 includes a main electromagnet 601, which is fixedly installed inside the fixed force arm 1. A driven electromagnet 602 is fixedly installed inside the movable force arm 2. Both the driven electromagnet 602 and the main electromagnet 601 are powered by the power supply 9. Through such a setting, electrical energy can be converted into magnetic energy to adsorb the two force arms, so as to complete the cutting.

[0029] Based on the above structure,

[0030] In one embodiment, the power supply 9 is connected to the driven electromagnet 602 through a wire 603. The wire 603 is embedded inside the fixed force arm 1 and the movable force arm 2. The shape of the wire 603 at the hinge shaft 3 is spiral. Through such a setting, the wire 603 can be accommodated, and at the same time, the spiral wire 603 can prevent the wire 603 from being broken during the operation of the movable force arm 2.

[0031] Based on the above structure,

[0032] In one embodiment, the power mechanism 6 includes a semi-tooth ring 604 concentric with the hinge shaft 3. The semi-tooth ring 604 is fixedly connected to the movable force arm 2. A power gear 605 meshing with the semi-tooth ring 604 is rotatably connected to the middle of the fixed force arm 1. A power source 606 for driving the power gear 605 to rotate is fixedly installed on the fixed force arm 1. Through such a setting, the movable force arm 2 can be driven to rotate to complete the cutting.

[0033] Based on the above structure,

[0034] In one embodiment, insertion interfaces 10 are provided on the inner sides of the fixed force arm 1 and the movable force arm 2. A plug-in block 11 is inserted into the interior of the insertion interface 10. The blade 4 is fixedly connected to the plug-in block 11. The plug-in block 11 is fixedly connected to the fixed force arm 1 or the movable force arm 2 by bolts 12. Such a setting facilitates the replacement of the blade 4. At the same time, inserting the plug-in block 11 from the inside out can ensure that the plug-in block 11 will not break from the force arm after being squeezed.

[0035] Based on the above structure,

[0036] In one embodiment, the bolt 12 includes a vertical bolt 121 and a horizontal bolt 122. The vertical bolt 121 penetrates the plug-in block 11 from top to bottom, and the horizontal bolt 122 penetrates the plug-in block 11 from front to back. By providing the vertical bolt 121 and the horizontal bolt 122, the spatial position of the blade 4 can be restricted, preventing the gap between the two blades 4 from being too large.

[0037] Based on the above structure,

[0038] In one embodiment, spring snap joints 13 are inlaid at both the upper end and the lower end on one side of the fixed handle 7. The spring snap joints 13 are snap-connected to the sliding handle 8. Such a setting can limit the position of the sliding handle 8.

[0039] When the pruning device for landscaping in this embodiment is in use, when used electrically, hold the fixed force arm 1 and the sliding handle 8, and drive the two blades 4 to approach each other through the power mechanism 6 to achieve cutting. Since both the fixed force arm 1 and the fixed handle 7 are fixed, they are not likely to fall off during the holding process. When it is necessary to adjust to manual use, slide the sliding handle 8 upward to expose the movable force arm 2. Manual cutting can be achieved by manually pressing the movable force arm 2. The upward movement of the sliding handle 8 does not affect the manual pressing of the movable force arm 2, thus achieving the effect of being convenient to use both after switching between manual and electric use.
