[0039] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0040] In the description of the embodiments of the present application, it should be understood that the terms "top", "bottom", and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0041] Referring to the drawings Figures 1-10 The present embodiment provides a plant pruning auxiliary device for greening planting, which comprises two groups of knife handles 1, two groups of knife heads 2 and elastic clamping pieces 3. The knife heads 2 are arranged at the long end of the knife handles 1, and the two groups of knife handles 1 are hinged on the side close to the knife heads 2, so as to open and close the two groups of knife heads 2 for shearing. The elastic clamping pieces 3 are arranged at the end of the knife heads 2, and the other end of the elastic clamping pieces 3 is inserted into the long end of the knife handles 1.

[0042] Specifically, the long end of the knife handle 1 is provided with a first insertion slot 111, and the first insertion slot 111 has at least a first opening 112 facing the knife head 2 and a second opening 113 extending radially along the knife handle 1. The elastic clamping piece 3 comprises a first insertion piece 31, a reset spring piece 32 and a second insertion piece 33. The first insertion piece 31 is inserted into the first opening 112. The reset spring piece 32 connects the first insertion piece 31 and the second insertion piece 33, and is used to drive the second insertion piece 33 to move radially along the knife handle 1 and be inserted into the second opening 113.

[0043] When it is needed to connect the shank 1 and the head 2, the second insert 33 and the reset spring 32 are extruded so that the combination of the second insert 33 and the reset spring 32 can enter the first slot 111 through the first opening 112, and as the elastic clamping piece 3 continuously goes deeper into the first slot 111, the second insert 33 gradually moves to the position corresponding to the second opening 113, and the second opening 113 does not extrude the second insert 33, and under the action of the reset spring 32, the second insert 33 moves along the radial direction of the shank 1 and is inserted into the second opening 113, so that the shank 1 and the head 2 form a stable clamping relationship. When it is needed to disassemble the shank 1 and the head 2, a relatively hard branch or rod-shaped object is used to extrude the second insert 33 from the outside of the shank 1, so that the second insert 33 is separated from the second opening 113, and under the premise of keeping the hard branch or rod-shaped object extruding the second insert 33, the head 2 is pulled along the axial direction of the shank 1, so that the elastic clamping piece 3 is separated from the shank 1, and then the head 2 can be disassembled.

[0044] By using the above scheme, the head 2 and the shank 1 can be stably connected, and compared with the existing bolt connection mode, the shank 1 and the head 2 are more convenient to assemble and disassemble, and the structure is more durable. Even if the elasticity of the reset spring 32 decreases after long-term use, it will not affect the disassembly of the head 2. After the head 2 is disassembled, a new reset spring 32 can be replaced, which solves the problem that the head 2 cannot be disassembled due to the sliding of the bolt in the existing bolt connection scheme.

[0045] In some more preferred embodiments, the first insert 31 is provided with a mounting groove 311, and the mounting groove 311 has at least a third opening 312 facing the shank 1 and a fourth opening 313 extending along the radial direction of the shank 1; the reset spring 32 is fixedly arranged in the mounting groove 311, and the second insert 33 is slidingly arranged in the fourth opening 313. The inner wall of the mounting groove 311 can protect the reset spring 32 to a certain extent, and the fourth opening 313 can guide and stabilize the sliding of the second insert 33 to a certain extent.

[0046] More specifically, the reset spring 32 can be arranged in a C-shaped structure, the open end of which is connected to the inner wall of the mounting groove 311, and the closed end thereof faces the second opening 113 and is connected to the second insert 33. When the second insert 33 extrudes the closed end of the reset spring 32, the closed end of the reset spring 32 bends away from the fourth opening 313, so that the second insert 33 is more withdrawn into the mounting groove 311, and when the external force acting on the second insert 33 disappears, the bent closed end of the reset spring 32 will spontaneously rebound, driving the second insert 33 to extend out of the mounting groove 311 more.

[0047] The size of the second plug-in 33 can be configured according to actual needs, and can be flush with the outer wall of the handle 1 at one end of the second plug-in 33 when the reset spring 32 is in a natural state, can be recessed in the outer wall of the handle 1, or can be protruding from the outer wall of the handle 1. When the last scheme is set, that is, when the reset spring 32 is in a natural state, one end of the second plug-in 33 protrudes from the outer wall of the handle 1, an anti-mis-touch cover 4 can be provided outside the second opening 113, the anti-mis-touch cover 4 is fixedly connected to the outer wall of the handle 1 and is sleeved outside the second plug-in 33. In order to facilitate disassembly of the tool bit 2, the anti-mis-touch cover 4 can be configured in a sleeve shape, so that one end of the sleeve corresponds to the second opening 113. Of course, the anti-mis-touch cover 4 can also be configured in a C-shaped structure and sleeved on the side of the second plug-in 33 that is easily touched.

[0048] In order to improve the connection stability of the tool bit 2 and the handle 1, a second slot 21 can be provided on the tool bit 2, and the second slot 21 has at least a fifth opening 22 facing the handle 1, and the handle 1 is provided with a third plug-in 5 matched with the second slot 21. The shapes of the second slot 21 and the third plug-in 5 can be flattened and elongated to increase the contact area of the tool bit 2 and the handle 1, improve the connection stability, and avoid concentrating all the forces borne by the tool bit 2 on the elastic clamping piece 3 when trimming plants, thereby improving the stability.

[0049] Referring to the accompanying drawings Figure 7 The handle 1 includes a curved portion 11 and a straight portion 12, both ends of the curved portion 11 (similar to S-shaped, its direction and connection method are prior art, which will not be described here) are connected to the straight portion 12 and the tool bit 2, respectively, and at least one straight portion 12 is provided with a storage belt 6. The storage belt 6 can be wound by a clockwork assembly 7 (prior art, which will not be described here) provided on the straight portion 12. When the handle 1 needs to be stored, the storage belt 6 is pulled out and wound around two groups of handles 1, so as to prevent the handles 1 from shaking and driving the tool bits 2 to shake, thereby causing harm to workers.

[0050] Magic tape, connecting buckles and the like can be adaptively provided on the storage belt 6, so as to stably wind and store the two groups of handles 1.

[0051] Referring to the accompanying drawings Figure 8The straight part 12 comprises a first blade rod 121, a second blade rod 122, a connecting rod 123 and a connecting sleeve 124. The two ends of the connecting rod 123 are rotatably connected with the first blade rod 121 and the second blade rod 122 respectively. The connecting sleeve 124 is sleeved on the connecting position of the first blade rod 121, the connecting rod 123 and the second blade rod 122. When the device is needed to be used, the first blade rod 121 and the second blade rod 122 are rotated, so that the first blade rod 121, the connecting rod 123 and the second blade rod 122 are coaxial, the connecting sleeve 124 is sleeved on the connecting position of the three, so that the three cannot continue to rotate relative to each other, and a relatively stable straight part 12 is formed to facilitate holding and operation. When the device is needed to be stored, the connecting sleeve 124 is removed, and the first blade rod 121 and the second blade rod 122 are rotated to be perpendicular to the connecting rod 123 and stacked. In this way, the space occupied by the straight part 12 during storage can be shortened. When the first blade rod 121 and the second blade rod 122 are stacked, the storage belt 6 can be used to wind them to prevent them from shaking and hurting people.

[0052] In some more preferable technical solutions, the outer wall of the second blade rod 122 is provided with an annular groove 125 coaxial with the second blade rod 122. The annular groove 125 is provided with a reset spring 126. The end of the reset spring 126 close to the first blade rod 121 abuts against an annular pressing plate 127. The annular pressing plate 127 is fixedly connected with the inner wall of the connecting sleeve 124. In this way, the connecting sleeve 124 can be always sleeved on the straight part 12 to prevent it from being lost after being removed. The position stability of the connecting sleeve 124 when the first blade rod 121 and the second blade rod 122 are coaxial is ensured through the extrusion of the reset spring 126 and the limiting of the annular groove 125. When the device is needed to be stored, the connecting sleeve 124 is slid in a direction away from the first blade rod 121, so that the connecting sleeve 124 is separated from the first blade rod 121, and the two ends of the connecting rod 123 are exposed. After the first blade rod 121 and the second blade rod 122 are stacked, the two are wound and fixed by the storage belt 6.

[0053] In order to facilitate the movement of the connecting sleeve 124, an annular protrusion 128 can be arranged on the outer wall of the connecting sleeve 124. When the straight part 12 is needed to be expanded, the annular protrusion 128 is pushed to move.

[0054] The method for using the device comprises: before pruning the plant, loosening the storage belt 6 that binds the first cutter bar 121 and the second cutter bar 122, rotating the first cutter bar 121 and the second cutter bar 122, making the first cutter bar 121, the connecting rod 123 and the second cutter bar 122 coaxial, under the action of the reset spring 126, the connecting sleeve 124 slides towards the direction of the first cutter bar 121, and is sleeved on the connecting position of the first cutter bar 121, the connecting rod 123 and the second cutter bar 122, so that the first cutter bar 121 and the second cutter bar 122 cannot rotate; inserting the third plug-in part 5 into the second insertion slot 21, in this process, the elastic clamping part 3 gradually approaches the first insertion slot 111, when it is needed to insert the elastic clamping part 3 into the first insertion slot 111, pressing the second plug-in part 33, making the reset spring 32 bend, making the size of the elastic clamping part 3 less than or equal to the size of the first opening 112, making the elastic clamping part 3 smoothly enter the first insertion slot 111, continuing to push the cutter head 2 towards the handle 1 until the second plug-in part 33 corresponds to the second opening 113, at this time, under the action of the reset spring 32, the second plug-in part 33 extends into the second opening 113, making the cutter head 2 and the handle 1 form a stable clamping relationship.

[0055] When the cutter head 2 needs to be replaced due to damage, a hard branch or rod is inserted into the anti-misoperation cover 4 to press the second plug-in part 33, so that the second plug-in part 33 is withdrawn into the first plug-in part 31 and separated from the second opening 113, and at the same time, the cutter head 2 is pulled away from the handle 1, so that the cutter head 2 and the handle 1 can be separated.

[0056] After pruning the plant, the annular protrusion 128 and the connecting sleeve 124 are pushed away from the first cutter bar 121, so that the connecting sleeve 124 is separated from the first cutter bar 121, and both ends of the connecting rod 123 are exposed, the first cutter bar 121 and the second cutter bar 122 are rotated to make their axes parallel and stacked, and the first cutter bar 121 and the second cutter bar 122 are wound and fixed by the storage belt 6.

[0057] Compared with the prior art, the present application has at least the following beneficial effects: the elastic clamping part 3 is used to connect the cutter head 2 and the handle 1, so that they can be quickly assembled and disassembled and stably connected, and the durability and maintenance convenience of the structure are better than those of the existing bolt connection technology; the first cutter bar 121 and the second cutter bar 122 are rotationally connected, and the reset spring 126 and the connecting sleeve 124 are used to construct the handle 1 that is easy to fold and unfold and stably connected, so that the storage volume of the device is small and the unfolding operation is convenient.

[0058] The above is the preferred embodiment of the present application, and it should be pointed out that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
