Description

Technical Field

[0001] This utility model proposes a garden greening maintenance device, belonging to the field of garden tools. Background Technology

[0002] After the growing season, the branches of the greenery grow to varying lengths, causing the originally neat greenery shape to become irregular. Therefore, garden maintenance workers need to prune and maintain the greenery regularly. Pruning tools can be manual or automatic.

[0003] For example, Chinese utility model patent CN222840146U specifically discloses a hedge trimmer, including a trimmer, a telescopic rod fixedly connected to the outer wall of the trimmer, a U-shaped block rotatably connected to the inner wall of the telescopic rod, a hydraulic rod fixedly connected to the bottom of the U-shaped block, a waist support mechanism at the bottom of the hydraulic rod, the waist support mechanism including a circular block, one end of a waist belt fixedly connected to the outer wall of the circular block, the other end of the waist belt slidably connected to the inner wall of the circular block, a pad A slidably connected to the outer wall of the waist belt, and the top of the circular block fixedly connected to the bottom of the hydraulic rod. The device is fixed to the operator's waist using a waist belt, but because the fulcrum between the trimmer and the hydraulic rod is at the rear end of the trimmer, the operator's arm needs to provide a large pulling force to ensure that the trimmer is horizontal or maintains a certain angle. Secondly, the hydraulic rod and the belt remain relatively fixed. During use, the distance between the rear end of the trimmer and the belt remains relatively fixed. In other words, the distance the trimmer extends relative to the belt is relatively fixed. This means that when trimming a wide and densely vegetated garden belt, the operator can only squeeze into the dense green belt to trim the distant green plants. Summary of the Invention

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] It should be noted that, for ease of description and definition... Figure 1 The left side is left, the right side is right, the front side is front, and the back side is back.

[0020] This embodiment presents a garden greening maintenance device. The purpose of this utility model is to provide a garden maintenance device that can control the pruning range of the pruner and can be controlled by the operator with only a small amount of force.

[0021] like Figures 1-3 As shown in the figure, this embodiment specifically discloses a garden greening maintenance device, including a fixing component 10 and a trimmer 20. When in use, the fixing component 10 is fitted and fixed to the operator's waist and provides support for the trimmer 20. The trimmer 20 is mounted on the fixing component 10, and the trimming side of the trimmer 20 is away from the fixing component.

[0022] In some embodiments, the fixing component 10 includes a front lumbar support 101 and a rear lumbar support 102. Both the front lumbar support 101 and the rear lumbar support 102 are arc-shaped plate structures. The arc-shaped front lumbar support 101 and the rear lumbar support 102 can form a large surface contact with the operator's waist, and the surface contact can evenly distribute the force applied outward. Referring to the accompanying drawings, in some embodiments, the front lumbar support 101 and the rear lumbar support 102 are connected by an elastic connecting strap. By adjusting the elastic tension of the elastic connecting strap between the front lumbar support 101 and the rear lumbar support 102, the front lumbar support 101 and the rear lumbar support 102 can be securely tied to the operator's waist. It should be noted that the elastic connecting strap mentioned here is the general term for the first elastic connecting strap and the second elastic connecting strap mentioned below.

[0023] See attached document Figure 1-3 As shown, a crossbar 103 is fixedly installed on the outer side of the front lumbar support 101. One end of the crossbar 103 is fixedly connected to the center of the outer side of the front lumbar support 101, and the other end extends radially outward along the front lumbar support 101. A U-shaped groove 104 is provided inside the crossbar 103 along the length direction of the crossbar 103. The upper side of the U-shaped groove 104 is open, and a vertical support rod 105 is slidably installed inside the U-shaped groove 104. A mounting bracket 106 for installing a trimmer is movably installed at the top of the vertical support rod 105. The trimmer 20 is fixedly installed on the upper side of the mounting bracket 106 by bolts. The extension distance of the trimmer 20 can be changed by sliding the vertical support rod 105 along the U-shaped groove 104.

[0024] In some embodiments, in order to ensure the rigidity of the front and rear lumbar supports, the front lumbar support 101 and the rear lumbar support 102 can be made of iron or alloy with high strength and hardness. The crossbar 103 and the vertical support bar 105 are also made of iron or alloy with high strength and hardness. Of course, in the process of material selection, alloys such as aluminum alloys, which are lighter in weight but have high strength, are preferred.

[0025] Specifically, the vertical support rod 105 includes a rod portion 1051. A sliding end 1052, fixedly connected to the rod portion 1051, is provided at the lower end of the rod portion 1051. The sliding end 1052 matches a U-shaped groove 104. The sliding end 1052 and the U-shaped groove 104 allow the vertical support rod 105 to be slidably upright. A ball head 1053 is provided at the upper end of the rod portion 1051. A ball seat 107 is provided on the lower side of the mounting frame 106. The mounting frame 106 is made of iron plate or aluminum alloy. The ball seat 107 is integrally connected to the mounting frame 106, and the ball head 1053 matches the ball seat 107. The mounting bracket 106 is mounted on the top of the vertical support rod 105 via a ball head and a ball seat, so that the mounting bracket 106 and the vertical support rod 105 can rotate with the ball head and ball seat as fulcrums. Of course, by applying a force along the direction of the horizontal bar 103 to the vertical support rod 105 through the mounting bracket 106, the mounting bracket 106 and the vertical support rod 105 can slide along the direction of the U-shaped slide groove 104, thereby changing the distance of the trimmer 20 mounted on the upper side of the mounting bracket 106 relative to the operation, that is, changing the extension distance of the trimmer 20 on the trimming side.

[0026] In some embodiments, to reduce the burden on the operator's arm, the ball seat 107 is disposed on the lower side of the mounting bracket 106 and near the front end of the mounting bracket 106. Thus, when the trimmer 20 is mounted on the upper side of the mounting bracket 106, the mounting bracket 106 forms a lever on both sides with the ball head and ball seat as fulcrums, allowing the operator to control the state of the trimmer or the mounting bracket with a small force. For operator convenience, a handle 108 is provided at the upper rear end of the bracket. The handle 108 also has a control button 1081 for controlling the trimmer. The operating state of the trimmer can be controlled by the control button 1081, and the pressing depth of the control button 1081 can change the trimming frequency of the trimmer.

[0027] Referring to the attached drawings, the front lumbar support 101 and the rear lumbar support 102 are fixedly connected on one side by a first elastic connecting strap 109a. A second elastic connecting strap 190b is fixedly provided on the other side of the rear lumbar support. A fixing hole 110 for fixing the second elastic connecting strap 109b is provided on the other side of the front lumbar support 101. A Velcro fastener (not shown in the figure) is provided at the end of the second elastic connecting strap 109b away from the rear lumbar support 102. Alternatively, the front lumbar support 101 and the rear lumbar support 102 can be connected in the following way: elastic connecting straps are fixedly connected to both sides of the rear lumbar support 102, and fixing holes for the elastic connecting straps are provided on both sides of the front lumbar support. In use, the elastic connecting straps pass through the fixing holes, fold, and are fixed by the Velcro fasteners at the ends of the elastic connecting straps. Of course, other fixing methods such as hook and loop fasteners can also be used.

[0028] To improve the user experience, a soft layer (not shown in the attached figure) is provided on the inner side of the arc-shaped plate structure. This soft layer can be made of fabric or sponge and is located on the inner arc side of the front and rear lumbar supports. In this way, the front and rear lumbar supports are isolated from the operator by the soft layer, reducing the rigid effect of the relatively hard front and rear lumbar supports on the operator.

[0029] To increase the contact area between the front and back lumbar supports and the operator, and to transfer the force of the front and back lumbar supports to the operator through surface contact as much as possible, the longitudinal height of the front lumbar support 101 and the back lumbar support 102 is 15-30cm.

[0030] To prevent the front lumbar support 101 and the back lumbar support 102 from being unable to breathe when in contact with the operator during prolonged wear of the device, several ventilation holes 111 are provided on the front lumbar support 101 and the back lumbar support 102.

[0031] The method of using this device is as follows: Apply the front lumbar support patch to the operator's front abdomen and the back lumbar support patch to the operator's lower back, and fix them with the connecting strap to ensure that the front and back lumbar supports are firmly held in the operator's lumbar region. Fix the trimmer to the upper side of the mounting frame with bolts to complete the wearing and installation. The operator holds the handle and presses the button to control the operation of the trimmer. Pushing the trimmer away from the operator by the handle can trim the greenery further away, and vice versa can trim the greenery in and out. By controlling the trimmer to rotate or swing around the ball head and ball seat as the fulcrum, the trimmer can be rotated or swung to trim.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
