[0002] Greening refers to the extensive planting of flowers, grasses, and trees to beautify and sanitize the environment and prevent soil erosion. Greening can improve environmental sanitation and play multiple roles in maintaining ecological balance. Pruning is a common construction method in greening operations, and the auxiliary equipment used for greening pruning is pruning shears. Workers hold pruning shears to prune plants, but the blades of traditional pruning shears are fixed in shape. After long-term use, the blades need to be sharpened, and the sharpening and maintenance process affects the use. When the blades are damaged, the entire device becomes useless, which is very wasteful.

[0003] Therefore, some scissors with detachable blades and bodies have appeared on the market. They are fixed with bolts, but the bolt fixing method is inconvenient, and repeated disassembly of bolts and screw holes can easily cause stripping. In addition, the force points of the blade and body are small, resulting in poor stability. Furthermore, the current scissors are generally long and inconvenient to carry. Utility Model Content

[0034] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] In the description of the embodiments of this utility model, it should be understood that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0036] Reference Appendix Figure 1-10 This embodiment provides a plant pruning auxiliary device for greening planting, which includes two sets of handles 1, two sets of blades 2, and an elastic locking member 3. The blades 2 are located at the long end of the handles 1, and the two sets of handles 1 are hinged on the side near the blades 2 to facilitate opening and closing the two sets of blades 2 for cutting. The elastic locking member 3 is located at the end of the blades 2, and the other end of the elastic locking member 3 is inserted into the long end of the handles 1.

[0037] Specifically, the long end of the handle 1 is provided with a first slot 111, the first slot 111 having at least a first opening 112 facing the blade head 2 and a second opening 113 extending radially along the handle 1; the elastic snap-fit ​​member 3 includes a first insert 31, a reset spring 32 and a second insert 33, the first insert 31 being inserted into the first opening 112; the reset spring 32 connecting the first insert 31 and the second insert 33, to drive the second insert 33 to move radially along the handle 1 and be inserted into the second opening 113.

[0038] When connecting the handle 1 and the blade 2, the second insert 33 and the reset spring 32 are pressed, allowing the assembly of the second insert 33 and the first insert 31 to enter the first slot 111 through the first opening 112. As the elastic locking member 3 continues to penetrate deeper into the first slot 111, the second insert 33 gradually moves to a position corresponding to the second opening 113. There is no pressure on the second insert 33 at the second opening 113. Under the action of the reset spring 32, the second insert 33 moves radially along the handle 1 and inserts into the second opening 113, forming a stable locking relationship between the handle 1 and the blade 2. When disassembling the handle 1 and the blade 2, the second insert 33 is pressed inward from the outside of the handle 1 using a relatively hard tree branch or rod-shaped object, causing it to disengage from the second opening 113. While maintaining the pressure from the hard tree branch or rod, the blade 2 is pulled axially along the handle 1, causing the elastic locking member 3 to disengage from the first opening 112.

[0039] The above solution not only enables a stable connection between the cutter head 2 and the cutter shank 1, but also makes installation and disassembly easier than the existing bolt connection method. The structure is also more durable. Even if the elasticity of the reset spring 32 decreases after long-term use, it will not affect the disassembly of the cutter head 2. After the cutter head 2 is disassembled, a new reset spring 32 can be replaced. This solves the problem that the cutter head 2 is difficult to disassemble due to stripping in the existing bolt connection solution.

[0040] In some preferred embodiments, the first insert 31 is provided with a mounting groove 311, which has at least a third opening 312 facing the tool holder 1 and a fourth opening 313 extending radially along the tool holder 1; the reset spring 32 is fixedly disposed in the mounting groove 311, and the second insert 33 is slidably disposed in the fourth opening 313. The inner wall of the mounting groove 311 can provide some protection for the reset spring 32, and the fourth opening 313 can also provide some guidance and stabilization for the sliding of the second insert 33.

[0041] More specifically, the reset spring 32 can be configured as a C-shaped structure, with its open end connected to the inner wall of the mounting groove 311, and its closed end facing the second opening 113 and connected to the second insert 33. When the second insert 33 presses the closed end of the reset spring 32, it bends the closed end away from the fourth opening 313, causing the second insert 33 to retract more into the mounting groove 311. When the external force on the second insert 33 disappears, the bent closed end of the reset spring 32 will spontaneously spring back, causing the second insert 33 to extend more out of the mounting groove 311.

[0042] The size of the second insert 33 can be configured according to actual needs. When the reset spring 32 is in its natural state, one end of the second insert 33 can be flush with the outer wall of the tool holder 1, or it can be recessed into the outer wall of the tool holder 1, or it can protrude from the outer wall of the tool holder 1. When configured in the last option, i.e., when the reset spring 32 is in its natural state and one end of the second insert 33 protrudes from the outer wall of the tool holder 1, an anti-accidental contact cover 4 can be constructed outside the second opening 113. The anti-accidental contact cover 4 is fixedly connected to the outer wall of the tool holder 1 and sleeved over the second insert 33. To facilitate the disassembly of the tool head 2, the anti-accidental contact cover 4 can be constructed in a sleeve shape, with one end of the sleeve corresponding to the second opening 113. Alternatively, the anti-accidental contact cover 4 can be constructed in a C-shape and sleeved on the side of the second insert 33 that is easily accidentally touched.

[0043] To improve the connection stability between the blade head 2 and the handle 1, a second slot 21 can be provided on the blade head 2. The second slot 21 has at least a fifth opening 22 facing the handle 1, and the handle 1 is provided with a third insert 5 that is adapted to the second slot 21. The shapes of the second slot 21 and the third insert 5 can both be flattened and elongated to increase the contact area between the blade head 2 and the handle 1, improve the connection stability, and avoid concentrating all the force borne by the blade head 2 when pruning plants on the elastic snap-fit ​​3, thereby improving stability.

[0044] Reference Appendix Figure 7 The handle 1 includes a curved portion 11 and a straight portion 12. The two ends of the curved portion 11 (similar to an S-shape, the orientation and connection method of which are prior art and will not be described in detail here) are respectively connected to the straight portion 12 and the blade head 2. At least one straight portion 12 is provided with a storage strap 6. The storage strap 6 can be wound up by a spring assembly 7 (prior art, which will not be described in detail here) provided on the straight portion 12. When it is necessary to store the handle 1, the storage strap 6 is pulled out and wrapped around the two sets of handles 1 to prevent the handle 1 from shaking and causing the blade head 2 to shake during storage or transportation, which could cause injury to the worker.

[0045] The storage strap 6 can be adapted to include Velcro, fasteners, etc., to facilitate the stable winding and storage of the two sets of knife handles 1.

[0046] Reference Appendix Figure 8 The straight section 12 includes a first cutter bar 121, a second cutter bar 122, a connecting rod 123, and a connecting sleeve 124. The two ends of the connecting rod 123 are rotatably connected to the first cutter bar 121 and the second cutter bar 122, respectively. The connecting sleeve 124 is fitted onto the connection point of the first cutter bar 121, the connecting rod 123, and the second cutter bar 122. When the device is to be used, the first cutter bar 121 and the second cutter bar 122 are rotated to make them coaxial. The connecting sleeve 124 is then fitted onto the connection point of the three components, preventing further relative rotation and forming a relatively stable straight section 12 for easy gripping and operation. When the device needs to be stored, the connecting sleeve 124 is removed, and the first cutter bar 121 and the second cutter bar 122 are rotated so that they are stacked perpendicular to the connecting rod 123. This reduces the space occupied by the straight section 12 during storage. When the first cutter bar 121 and the second cutter bar 122 are stacked, a storage strap 6 can be used to wrap them to prevent them from shaking and injuring people.

[0047] In some preferred technical solutions, the outer wall of the second cutter bar 122 is provided with an annular groove 125 coaxial with it. A return spring 126 is provided in the annular groove 125. The end of the return spring 126 near the first cutter bar 121 abuts against an annular pressure plate 127. The annular pressure plate 127 is fixedly connected to the inner wall of the connecting sleeve 124. In this way, the connecting sleeve 124 can be always fitted on the straight part 12 to prevent loss after removal. The compression of the return spring 126 and the limiting of the annular groove 125 ensure the positional stability of the connecting sleeve 124 when the first cutter bar 121 and the second cutter bar 122 are coaxial. When it is necessary to store the device, the connecting sleeve 124 is slid away from the first cutter bar 121 to separate the connecting sleeve 124 from the first cutter bar 121, exposing both ends of the connecting rod 123. After rotating and stacking the first cutter bar 121 and the second cutter bar 122, they can be wrapped and fixed with the storage strap 6.

[0048] To facilitate the movement of the connecting sleeve 124, an annular protrusion 128 can be provided on the outer wall of the connecting sleeve 124. When it is necessary to retract or expand the straight part 12, the annular protrusion 128 can be pushed.

[0049] The method of using this device includes: before pruning the plant, loosening the storage strap 6 that binds the first blade 121 and the second blade 122, rotating the first blade 121 and the second blade 122 to make the first blade 121, the connecting rod 123, and the second blade 122 coaxial; under the action of the return spring 126, the connecting sleeve 124 slides towards the first blade 121 and is fitted onto the connection part of the first blade 121, the connecting rod 123, and the second blade 122, so that the first blade 121 and the second blade 122 cannot rotate; inserting the third insert 5 into the second slot 21. During this process, the elastic snap-fit ​​3 gradually approaches the first slot 111. When it is necessary to insert the elastic snap-fit ​​3 into the first slot 111, the second insert 33 is pressed, causing the reset spring 32 to bend, so that the size of the elastic snap-fit ​​3 is less than or equal to the size of the first opening 112, allowing the elastic snap-fit ​​3 to smoothly enter the first slot 111. The cutter head 2 continues to be pushed towards the tool holder 1 until the second insert 33 corresponds to the second opening 113. At this time, under the action of the reset spring 32, the second insert 33 extends into the second opening 113, so that the cutter head 2 and the tool holder 1 form a stable snap-fit ​​relationship.

[0050] When the blade head 2 is damaged and needs to be replaced, use a hard tree branch or rod to insert into the anti-accidental contact cover 4 and squeeze the second insert 33, so that the second insert 33 retracts more into the first insert 31 and separates from the second opening 113. At the same time, pull the blade head 2 away from the handle 1 to separate the blade head 2 from the handle 1.

[0051] After pruning the plant, push the annular protrusion 128 and the connecting sleeve 124 away from the first blade 121 to separate the connecting sleeve 124 from the first blade 121, exposing both ends of the connecting rod 123. Rotate the first blade 121 and the second blade 122 so that their axes are parallel and overlapped. Use the storage strap 6 to wrap and fix them.

[0052] Compared with the prior art, the present invention has at least the following advantages: the use of elastic snap-fit ​​3 to connect the cutter head 2 and the cutter handle 1 enables them to be quickly installed and disassembled and stably connected, and the durability and maintenance convenience of the structure are superior to the existing bolt connection technology; the use of the first cutter bar 121 and the second cutter bar 122 for rotational connection, as well as the return spring 126 and the connecting sleeve 124, constructs a cutter handle 1 that is easy to retract and stably connected, making the storage volume of the device small and the unfolding operation convenient.

[0053] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
