[0021] The present utility model will be further described below in conjunction with the accompanying drawings through specific embodiments, but it is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention.
[0022] Embodiment 1
[0023] A pruning device for horticultural branches and stems described in this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, includes two scissor blades 1. Connecting plates 5 are fixed on both of the two scissor blades 1. The two connecting plates 5 are hinged by a scissor shaft. A handle 12 is arranged on the connecting plate 5. A fixing plate 4 is fixed on the scissor shaft. Clamping rods 2 which are symmetrically distributed and have an "L" - shaped structure are hinged on the fixing plate 4. An installation plate 7 is arranged on the connecting plate 5. A first sliding groove is opened at the top of the installation plate 7. A first sliding block 8 which is in sliding fit with the first sliding groove is arranged in the first sliding groove. The first sliding block 8 and the clamping rod 2 are hinged by a hinged rod 6. A fixing component for restricting the rotation of the clamping rod 2 to clamp the branches and stems is arranged on the installation plate 7; One end of the scissor blade 1 is welded with the connecting plate 5. A cutting edge is opened on the side wall of the other end of the scissor blade 1. The scissor blade 1 and the connecting plate 5 are of an integrally formed structure, which is convenient for production and makes its structure more firm; Through holes are opened on both of the two connecting plates 5. The scissor shaft passes through the through holes to hinge the two connecting plates 5 in an up - and - down distribution. The movable ends of the connecting plates 5 are welded or pasted with handles 12. The staff holds one handle 12 with each hand, separates the two handles 12, makes the connecting plate 5 drive the scissor blade 1 to rotate around the hinge point of the scissor shaft, separates the two scissor blades 1, and prunes the branches and stems of the tree. Through pruning, the tree can maintain a good crown shape and tree vigor, which is beneficial for the branches to absorb nutrients and water and promotes the healthy growth of the tree; Through pruning, the ventilation and light transmission can also be improved, which is conducive to cleaning dead and diseased branches and stems, preventing the spread of pests and diseases, improving the disease resistance of the tree, and also beneficial for ensuring the beautiful appearance of the tree;
[0024] Both ends of the scissors shaft protrude from both sides of the connecting plate 5, and a fixing plate 4 is welded or glued to the top of the protruding scissors shaft. Two symmetrically distributed clamping rods 2 are hinged on the top of the fixing plate 4. The middle section of the clamping rod 2 is hinged on the top of the fixing plate 4, and the clamping end of the clamping rod 2 is close to the direction of the scissors blade 1. The movable end of the clamping rod 2 is hinged with a hinge rod 6, and the other end of the hinge rod 6 is hinged on the top of the first slider 8. The movable end of the clamping rod 2 is hinged to the top of the first slider 8 through the hinge rod 6. When the first slider 8 moves in the first slide groove, the movable end of the clamping rod 2 is caused to rotate around the hinge point of the fixing plate 4 under the cooperation of the hinge rod 6, so that the clamping ends of the two clamping rods 2 are close to each other to clamp the branches of the tree, so as to avoid displacement of the branches during pruning and affect the pruning speed of the branches.
[0025] The cross section of the first slide groove opened on the top of the mounting plate 7 is a "T"-shaped structure, and the cross section of the first slider 8 in the first slide groove is an "I"-shaped structure. A vertical plate is vertically arranged at the bottom of the top plate of the first slider 8, and a bottom plate is horizontally arranged at the bottom of the vertical plate. The top plate of the first slider 8 is located at the top of the mounting plate 7, and the bottom of the top plate of the first slider 8 contacts the top of the mounting plate 7. The vertical plate and the bottom plate of the first slider 8 are both embedded in the first slide groove and move, ensuring that the first slider 8 moves steadily and smoothly in the first slide groove, and also preventing the first slider 8 from falling off from the first slide groove;
[0026] The mounting plate 7 is provided with a fixing assembly for fixing the clamping rod 2, and the fixing assembly includes a threaded hole opened on the first sliding block 8, and the top plate of the first sliding block 8 is provided with a threaded hole communicating with each other from top to bottom, and a screw is connected to the thread in the threaded hole, and the top tightening end of the screw presses against the top of the mounting plate 7. When in use, the first sliding block 8 is moved to make it move in the first sliding groove, and the movement of the first sliding block 8 drives the hinged rod 6 hinged on the top of the first sliding block 8 to rotate, thereby driving the movable end of the clamping rod 2 to rotate around the hinge point on the top of the fixing plate 4, so that the clamping ends of the two clamping rods 2 are close to each other to clamp the branches, and then tighten the screw so that the top tightening end presses against the top of the mounting plate 7, thereby fixing the first sliding block 8 in the first sliding groove, and then fixing the positions of the hinged rod 6 and the clamping rod 2, so that the clamping rod 2 can better assist the scissors blade 1 to prune the branches, avoid displacement when pruning the branches, and improve its pruning speed;
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the articulated rod 6 is articulated with the first slider 8 through the articulated column 17, and the two connecting plates 5 are articulated in an up-and-down distribution. To prevent the two articulated rods 6 from overlapping, one end of one articulated rod 6 is articulated at the top of the fixed plate 4, and the other end is articulated at the top of the first slider 8 through the articulated column 17; one end of the other articulated rod 6 is articulated at the bottom of the fixed plate 4, and the other end is articulated at the top of the first slider 8, so that the two articulated rods 6 are staggered up and down, without affecting the articulated rod 6 driving the clamping rod 2 to rotate around the articulated point at the top of the fixed plate 4, and can better clamp and fix the branches,
[0028] As Figure 1 , Figure 2 and Figure 6 shown, a number of saw teeth 3 are provided on the inner side wall of the clamping rod 2, and a number of saw teeth 3 are provided on the inner side wall of the clamping end of the clamping rod 2. When the inner side wall of the clamping end of the clamping rod 2 contacts and clamps the branch, the number of saw teeth 3 saw the branch, which can increase the friction between the clamping rod 2 and the branch, ensure that the clamping rod 2 better clamps and fixes the branch, and avoid the branch shifting during the pruning process, which affects the pruning speed of the branch;
[0029] As Figure 1 , Figure 2 and Figure 6 shown, an anti-slip sleeve 10 is sleeved on the handle 12. The anti-slip sleeve 10 is sleeved on the handle 12 and is made of rubber material. The rubber is soft and elastic, which can protect the hand and prevent the hand from being damaged when the staff holds the handle 12 for a long time to prune the branch; and the outer side wall of the anti-slip sleeve 10 is provided with anti-slip lines, and the anti-slip lines on the outer side wall of the anti-slip sleeve 10 can increase the friction between the anti-slip sleeve 10 and the hand, avoid slipping caused by sweating of the hand, and can better prune the branch.
[0030] During the actual use process, the staff holds one handle 12 with each hand. When the two hands are separated, the two handles 12 drive the connecting plate 5 to rotate around the articulated point of the scissors shaft, so that the two scissors blades 1 are separated, and the scissors blades 1 are used to prune the branches of the tree. When it is necessary to clamp the branch to be pruned, the fixing component is loosened, so that the first slider 8 moves in the first chute on the top of the mounting plate 7. The movement of the first slider 8 drives the articulated rod 6 articulated at the top of the first slider 8 to rotate. The articulated rod 6 drives the clamping rod 2 to rotate around the articulated point at the top of the fixed plate 4, so that the clamping ends of the two clamping rods 2 approach each other, clamp and fix the branch, and then fix the position of the first slider 8 through the fixing component, and further fix the position of the clamping rod 2, so that it firmly clamps the branch, and then uses the scissors blade 1 to prune the branch, which can clamp it during the pruning process, avoid its displacement, and thus improve the pruning speed of the branch.
[0031] Embodiment 2
[0032] This embodiment will further illustrate the technology. For example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 as shown, the fixing component includes a limiting groove 18 opened at the bottom of the first sliding groove. The limiting groove 18 is connected and communicated with the first sliding groove through a fixing groove. A connecting rod 16 is arranged in the fixing groove. The top end of the connecting rod 16 passes through the top of the first slider 8 and is connected with a button 9. A spring 15 is sleeved on the connecting rod 16 and is fixed between the top of the first slider 8 and the bottom of the button 9. The bottom end of the connecting rod 16 extends into the limiting groove 18 and is connected with a metal block 14. A magnet 13 that attracts the metal block 14 is arranged at the top inside the limiting groove 18; the limiting groove 18 opened at the bottom of the first sliding groove is connected and communicated through the fixing groove. A connecting rod 16 is arranged at the fixing groove. A fixing hole connected and communicated with the fixing groove is opened on the first slider 8. The connecting rod 16 is independently inserted into the fixing hole. After the top of the connecting rod 16 passes through the fixing hole, it is welded or glued with a button 9. A spring 15 is sleeved on the top section of the connecting rod 16 passing through the fixing hole. One end of the spring 15 is welded to the bottom of the button 9, and the other end of the spring 15 is welded to the top of the first slider 8. The bottom end of the connecting rod 16 is welded or glued with a metal block 14. The metal block 14 is located in the limiting groove 18, and a magnet 13 is glued to the top inside the limiting groove 18. During use, the metal block 14 and the magnet 13 are adhesively attached to each other, thereby fixing the connecting rod 16, the button 9, and the first slider 8 in the first sliding groove of the mounting plate 7, thereby fixing the articulated rod 6 and also fixing the position of the clamping rod 2; during use, when it is necessary for the clamping rod 2 to clamp the branches of a tree, the staff holds the handle 12 with the hand and presses the button 9 with the thumb. The button 9 drives the connecting rod 16 to move downward. The downward movement of the connecting rod 16 separates the metal block 14 from the magnet 13. The bottom of the metal block 14 contacts the bottom inside the limiting groove 18. Then, the button 9 is moved to drive the first slider 8 to move in the first sliding groove. The movement of the first slider 8 in the first sliding groove causes the articulated rod 6 articulated at the top of the first slider 8 to rotate, thereby driving the clamping rod 2 to rotate around the hinge point hinged on the fixing plate 4. The clamping ends of the two clamping rods 2 approach each other, and the clamping rod 2 clamps the branches to be pruned. Then, the two scissor blades 1 are used to prune them, avoiding the displacement of the branches during pruning and affecting the pruning speed of the branches; after the clamping rod 2 clamps the branches, the button 9 is released. Under the elastic force of the spring 15, the spring 15 drives the button 9 to move upward. The button 9 drives the connecting rod 16 and the metal block 14 to move upward. The metal block 14 is attracted to the magnet 13 at the bottom inside the limiting groove 18 again, thereby fixing the button 9 again and also fixing the first slider 8 again, fixing the position of the clamping rod 2, which can greatly avoid the loosening of the branches and maintain the high efficiency of pruning;
[0033] Embodiment 3
[0034] This embodiment will further illustrate the technology. For example Figure 1 , Figure 2 and Figure 6 As shown, one end of the handle 12 is provided with a groove for the connecting plate 5 to extend into. Two symmetrically distributed first sliding grooves are provided on the inner wall of the groove. Second sliders 11 that are in sliding fit with the first sliding grooves and fixed on the connecting plate 5 are arranged in the first sliding grooves; the movable end of the connecting plate 5 is embedded in the groove of the handle 12. The second sliders 11 are welded or adhered to the side wall of the connecting plate 5. The second sliders 11 move in the second sliding grooves. When in use, the handle 12 is moved to make the connecting plate 5 move in the groove, so that the connecting plate 5 is moved out of the handle 12, increasing the lengths of the connecting plate 5 and the handle 12, facilitating the pruning of branches at higher positions, making it more practical. Moreover, the handle 12 is made of a metal material, such as iron, cobalt or nickel, and the second sliders 11 are made of magnets. The second sliders 11 are attracted to iron, cobalt or nickel, so that the second sliders 11 can not only move in the handle 12, but also fix the connecting plate 5 in the handle 12, making it more stable.
