Description
Technical Field
[0001] This utility model relates to the field of pruning device technology, and in particular to a garden pruning device specifically for landscaping. Background Technology
[0002] Garden pruning equipment is an indispensable tool in garden greening maintenance. It helps gardeners complete pruning tasks efficiently and accurately, maintain the beauty and cleanliness of the garden, and reduce the labor intensity and cost of manual pruning. Hedge trimmers are a commonly used type of garden greening pruning equipment.
[0003] Hedge trimmers generate kinetic energy from gasoline combustion or batteries, which is transmitted to double-edged blades via a transmission mechanism, thus driving the blades to perform garden trimming operations. The double-edged blades are quite sharp, and they are directly exposed. If the operator's body parts come into contact with the double-edged blades or the blades come into contact with other objects while carrying the hedge trimmer, it may cause injury to the operator or damage to other objects, posing a certain safety hazard. Utility Model Content
[0004] This utility model is a garden pruning device specifically designed for landscaping, which addresses the safety hazard that may occur if the operator's body comes into contact with the double-edged blade or the double-edged blade comes into contact with other objects while carrying a hedge trimmer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a garden pruning device for landscaping, comprising a housing, a handle fixedly installed on the outer surface of the housing, a baffle fixedly installed on one side of the housing, a saw blade installed inside the housing, double-edged blades installed on both sides of the saw blade, the saw blade and the double-edged blades being disposed inside the baffle, and a protective device installed on one side of the baffle, the protective device providing protection by blocking one side of each of the two double-edged blades through two protective plates respectively.
[0006] The effect achieved by the above-mentioned components is that by setting two protective plates to block one side of the two double-edged blades, it helps to prevent the operator's body parts from directly touching the double-edged blades or the double-edged blades from touching other objects during the process of carrying the hedge trimmer, which can reduce safety hazards to a certain extent.
[0007] Preferably, the protective device includes two protective plates, which are symmetrically arranged on one side of two double-edged blades. The inner walls of the two protective plates are slidably provided with the same rectangular plate. A trapezoidal block is fixedly installed at one end of each protective plate. The rectangular plate is arranged on one side of the two trapezoidal blocks. A triangular block is symmetrically fixedly connected to one side of the baffle. One side of the trapezoidal block is slidably arranged on one side of the triangular block. A threaded rod is rotatably connected to the inner wall of the rectangular plate through a bearing. A connecting block is threadedly connected to the outer surface of the threaded rod. The connecting block is fixedly installed on one side of the baffle.
[0008] The effect achieved by the above components is as follows: By setting two protective plates, under the action of the threaded rod, rotating the threaded rod will cause it to extend and retract on the inner wall of the connecting block. During the extension and retraction of the threaded rod, it will drive the rectangular plate to move downward. The rectangular plate will then drive the trapezoidal block connected to the protective plate to slide on one side of the triangular block. At the same time, the protective plate will also slide on the outer surface of the rectangular plate, causing the two protective plates to move away from each other until the two protective plates completely cover one side of the two double-edged blades. This helps to prevent the operator's body parts from directly touching the double-edged blades or the double-edged blades from touching other objects. Simultaneously, rotating the threaded rod in the opposite direction will cause the two protective plates to move upward and bring them closer together. Then, the two protective plates will no longer obstruct the double-edged blades, facilitating the normal progress of garden pruning work.
[0009] Preferably, both ends of the rectangular plate are fixedly installed with blocks, and the blocks are located on one side of the triangular block.
[0010] The effect achieved by the above components is as follows: by setting two blocks, they can block the two ends of the rectangular plate respectively, which helps to prevent the protective plate from falling off the limit of the rectangular plate due to accidental operation. At the same time, the side of the block is set with a triangular block, that is, one side of the block will not exceed one side of the triangular block, in order to prevent the triangular block from blocking the movement of the block and the rectangular plate.
[0011] Preferably, rubber strips are fixedly installed on the top and bottom of the two adjacent protective plates, and the vertical cross-section of the rubber strips is triangular.
[0012] The effect achieved by the above components is that the two rubber strips can respectively shield both sides of the double-edged blade, which can improve the protective performance of the protective plate. At the same time, the triangular rubber strips, which are narrow on one side and wide on the other, make it easier for the rubber strips to deform when passing through the double-edged blade, reducing the damage caused by the double-edged blade to the rubber strips.
[0013] Preferably, one end of the threaded rod is fixedly connected to an operating block, and the outer surface of the operating block is provided with protrusions.
[0014] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.
[0015] Preferably, the locking device includes two screw hole blocks, which are fixedly installed on one side of the trapezoidal block and on one side of the triangular block, and the inner wall of the screw hole blocks is threaded with bolts.
[0016] The effect achieved by the above components is as follows: by rotating the bolt, one end of the bolt abuts against one side of the triangular block, the threaded pin can use the friction between itself and the triangular block to assist in fixing the protective plate and the triangular block, which helps to prevent the protective plate from moving due to loosening of the threaded rod.
[0017] Preferably, a rubber sheet is adhered to the inner wall of one side of the triangular block. The rubber sheet is disposed on one side of the screw hole block.
[0018] The effect achieved by the above components is that by setting the rubber plate, the friction between the triangular block and the bolt can be increased, making the bolt more securely fixed to the protective plate.
[0019] Preferably, the same threaded slide rod is inserted into the inner wall of one end of the two protective plates, and nuts are provided on both sides of the protective plates. The outer surface of the threaded rod is threadedly connected to the inner wall of the four nuts.
[0020] The effect achieved by the above components is as follows: the overall length of the protective plate is relatively long, and fixing only one end of the protective plate may make it difficult to synchronize the other end. However, by setting a threaded slide bar, after the position of the protective plate is adjusted, rotating the two nuts on both sides of the protective plate will cause one side of the nut to abut against one side of the protective plate, so that the nut can provide auxiliary limiting and fixing for the other end of the protective plate.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting two protective plates, the threaded rod can drive the two protective plates away from each other until the two protective plates block one side of the two double-edged blades respectively. This helps to prevent the operator's body from directly touching the double-edged blades or the double-edged blades from touching other objects during the process of carrying the hedge trimmer, thereby reducing safety hazards.

[0028] Example 1, referring to Figures 1-3As shown, this embodiment discloses a garden pruning device specifically for landscaping, including a housing 1. A handle 2 is fixedly installed on the outer surface of the housing 1, and a baffle 3 is fixedly installed on one side of the housing 1. A saw blade 4 is disposed inside the housing 1, and double-edged blades 5 are disposed on both sides of the saw blade 4. The saw blade 4 and the double-edged blades 5 are disposed inside the baffle 3. A gasoline engine is disposed inside the housing 1. The power generated by gasoline combustion is transmitted to the double-edged blades 5 through the transmission mechanism inside the housing 1 and the saw blade 4, thereby driving the double-edged blades 4 to perform pruning. The shearing device 6 includes two protective plates 61, which are symmetrically arranged on one side of the two double-edged blades 5. A rectangular plate 62 is slidably mounted on the inner wall of each of the two protective plates 61. A trapezoidal block 63 is fixedly installed at one end of each protective plate 61. The rectangular plate 62 is located on one side of the two trapezoidal blocks 63. A triangular block 64 is symmetrically fixedly connected to one side of the shearing device 3. One side of the trapezoidal block 63 is slidably mounted on one side of the triangular block 64. The inner wall of the rectangular plate 62 is rotatably connected via bearings. A threaded rod 65 is connected to a connecting block 66, which is threaded onto the outer surface of the threaded rod 65. The connecting block 66 is fixedly installed on one side of the baffle 3. By setting two protective plates 61, the threaded rod 65 is rotated under the action of the threaded rod 65. The threaded rod 65 will extend and retract on the inner wall of the connecting block 66. During the extension and retraction of the threaded rod 65, it will drive the rectangular plate 62 to move downward. The rectangular plate 62 will drive the trapezoidal block 63 connected to the protective plate 61 to slide on one side of the triangular block 64. At the same time, the protective plate 61 will also slide on the outer surface of the rectangular plate 62, so that the two protective plates 61 move away from each other until the two protective plates 61 completely cover one side of the two double-edged blades 5. This helps to prevent the operator's body parts from directly touching the double-edged blades 5 or the double-edged blades 5 from touching other objects. At the same time, rotating the threaded rod 65 in the opposite direction will drive the two protective plates 61 to move upward and bring them closer together. Then the two protective plates 61 will no longer obstruct the double-edged blades 5, which will facilitate the normal operation of garden pruning.
[0029] Reference Figure 2 and Figure 3 As shown, two stops 67 are fixedly installed at both ends of the rectangular plate 62. The stops 67 are located on one side of the triangular block 64. By setting two stops 67, they can block the two ends of the rectangular plate 62 respectively, which helps to prevent the protective plate 61 from being separated from the limit of the rectangular plate 62 due to accidental operation. At the same time, the baffle 3 is located on one side of the triangular block 64, that is, one side of the baffle 3 will not exceed one side of the triangular block 64, in order to prevent the triangular block 64 from blocking the movement of the stops 67 and the rectangular plate 62.
[0030] Reference Figures 2-4As shown, rubber strips 68 are fixedly installed on the top and bottom of the two protective plates 61 on the side that are close to each other. The vertical cross-section of the rubber strips 68 is triangular. The two rubber strips 68 can respectively shield both sides of the double-edged blade 5, which can improve the protective performance of the protective plate 61. At the same time, the triangular rubber strips 68 are narrower on one side and wider on the other side, which makes it easier for the rubber strips 68 to deform when passing through the double-edged blade 5, reducing the damage caused by the double-edged blade 5 to the rubber strips 68. One end of the threaded rod 65 is fixedly connected to an operating block 69. The outer surface of the operating block 69 is provided with protrusions. By setting the operating block 69, rotating the operating block 69 can drive the threaded rod 65 to rotate. At the same time, the protrusions on the outer surface of the operating block 69 can effectively increase the friction of the outer surface of the operating block 69, which has an anti-slip effect when rotating the operating block 69.
[0031] Reference Figure 2 and Figure 3 As shown, the locking device includes two screw-hole blocks 71. The screw-hole blocks 71 are fixedly installed on one side of the trapezoidal block 63 and on one side of the triangular block 64. Bolts 72 are threaded into the inner walls of the screw-hole blocks 71. Rotating the bolts 72 causes one end of the bolt to abut against one side of the triangular block 64. The threaded pin can then use the friction between itself and the triangular block 64 to provide auxiliary fixation between the protective plate 61 and the triangular block 64, which helps prevent the protective plate 61 from moving due to loosening of the threaded rod 65. A rubber plate 73 is adhered to the inner wall of one side of the triangular block 64. The rubber plate 73 is located on one side of the screw-hole blocks 71. By setting the rubber plate 73, the friction between the triangular block 64 and the bolt 72 can be increased, making the bolt 72 more securely fixed to the protective plate 61.
[0032] Reference Figure 2 and Figure 4 As shown, the inner wall of one end of each of the two protective plates 61 is fitted with the same threaded slide rod 74. Nuts 75 are provided on both sides of the protective plate 61. The outer surface of the threaded rod 65 is threadedly connected to the inner wall of the four nuts 75. The overall length of the protective plate 61 is relatively long. If only one end of the protective plate 61 is fixed, the other end may be difficult to synchronize. However, by setting the threaded slide rod 74, after the position of the protective plate 61 is adjusted, the two nuts 75 on both sides of the protective plate 61 are rotated so that one side of the nut 75 abuts against one side of the protective plate 61. Then the nut 75 can provide auxiliary limiting and fixing for the other end of the protective plate 61.
[0033] Working principle: Rotating the operating block 69 drives the threaded rod 65 to rotate. The threaded rod 65 extends and retracts on the inner wall of the connecting block 66. During the extension and retraction of the threaded rod 65, it drives the rectangular plate 62 to move downwards. The rectangular plate 62 drives the trapezoidal block 63 connected to the protective plate 61 to slide on one side of the triangular block 64. At the same time, the protective plate 61 also slides on the outer surface of the rectangular plate 62, causing the two protective plates 61 to move away from each other until the two protective plates 61 completely cover one side of each of the two double-edged blades 5. Then, rotating the bolt 72 causes one end of the bolt 72 to abut against the rubber plate 73 on one side of the triangular block 64. The threaded pin can then protect the protective plate 64 through the friction between itself and the triangular block 64. The auxiliary fixation between plate 61 and triangular block 64 helps prevent the protective plate 61 from moving due to loosening of threaded rod 65. Finally, rotating the two nuts 75 on both sides of the protective plate 61 so that one side of nut 75 abuts against one side of the protective plate 61, the nuts 75 can provide auxiliary limit and fixation for the other end of the protective plate 61, which helps prevent the operator's body parts from directly touching the double-edged blade 5 or the double-edged blade 5 from touching other objects. At the same time, rotating the threaded rod 65 in the opposite direction will drive the two protective plates 61 to move upward and bring them closer together, so that the two protective plates 61 will no longer obstruct the double-edged blade 5, facilitating the normal progress of garden pruning work.
