Description

Technical Field

[0001] This utility model relates to the field of hedge trimmer technology, and specifically to a hedge trimmer with an adjustable operating angle. Background Technology

[0002] A hedge trimmer is a gardening tool equipped with cutting blades or serrations for trimming hedges, shrubs, branches, etc. Using a hedge trimmer allows for quick and even trimming of plants, maintaining their ideal shape and height.

[0003] Some patents, such as the one with authorization announcement number CN219046787U, provide a double-blade trimmer and its handle rotation mechanism, which includes a housing and a first handle that are rotatably connected. A switch is provided below the first handle, and a telescopic fixing block is provided. The fixing block can restrict the rotation between the housing and the first handle. By pulling the fixing block, the rotation restriction between the housing and the first handle can be unlocked.

[0004] During operation, by pulling the fixed block, the angle restriction between the housing and the first handle can be unlocked. While ensuring that the gripping angle of the first handle remains unchanged, the housing part of the hedge trimmer with blades can be rotated to adjust the angle, so that the trimming angle can be adjusted without rotating the whole machine during trimming.

[0005] However, when pulling the fixed block, the hand extends the fingers to a far position while holding the first handle, and the fingertips bend to pull the fixed block. This hand operation has a large range of motion and a long movement path, which will mobilize more forearm and hand muscles to work together, making the angle adjustment operation more strenuous. Moreover, after repeating it many times, the muscles continue to contract and relax, which will accelerate the feeling of fatigue. Utility Model Content

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes a hedge trimmer with an adjustable angle that makes angle adjustment easier to operate, as detailed below: like Figures 1-5 As shown, the adjustable hedge trimmer includes a rear shell 1, a front shell 2, a rotation limiting member 3, and an elastic member 4. The rear shell 1 has a forward-extending rotating shaft 11, and the front shell 2 has a rotating hole 21 that passes through the rotating shaft 11. The end of the rotating shaft 11 has a limiting part 12 with an outer diameter larger than the inner diameter of the rotating hole 21. The limiting part 12 restricts the rotational separation between the front shell 2 and the rear shell 1. The rotation limiting member 3 has a locking part 31 that is inserted into the front shell 2. The front shell 2 has several limiting openings 22. The elastic member 4 is installed in the rear shell 1 and elastically acts on the rotation limiting member 3, so that the locking part 31 on the rotation limiting member 3 falls into the limiting openings 22, restricting the rotation between the front shell 2 and the rear shell 1.

[0024] Preferably, when the locking part 31 on the limiting member 3 falls into different limiting holes 22, the angle between the rear shell 1 and the front shell 2 is different.

[0025] In this embodiment, the rear shell 1 is provided with a rear grip 13 extending forward and backward, the elastic member 4 has a rearward elastic force on the rotation limiting member 3, and the rotation limiting member 3 is provided with a pressure-bearing part 32 exposed at the lower front position of the rear grip 13. Preferably, the pressure-bearing part 32 has a slope or arc-shaped slope structure that is higher in the front and lower in the back.

[0026] In this application, by pushing the pressure part 32 of the rotation limiting member 3, the rotation limiting member 3 compresses the elastic member 4, and the locking part 31 of the rotation limiting member 3 moves out of the limiting port 22, thereby unlocking the rotation restriction between the front shell 2 and the rear shell 1. This allows the front shell 2 and the rear shell 1 to be directly rotated and adjusted. Furthermore, the pushing operation has a small range of motion and a simple path, allowing for short-distance direct pushing, reducing unnecessary muscle contraction, reducing fatigue, and making the unlocking operation more effortless and reducing fatigue during repeated operations.

[0027] like Figures 3-5As shown, the rear shell 1 is provided with a through groove 14, which connects the interior of the front shell 2 and the lower front position of the rear grip 13 on the rear shell 1. The rotation limiting member 3 is provided with an extension section 33 that is inserted into the through groove 14. The pressure-receiving part 32 and the locking part 31 are provided at both ends of the extension section 33, and the locking part 31 protrudes from the extension section 33. Preferably, the outer dimension of the locking part 31 is larger than the outer dimension of the extension section 33.

[0028] In this embodiment, the rear shell 1 is also provided with a rear-opening insertion cavity 15. The elastic member 4 is a spring and is installed in the insertion cavity 15. The rotation limiting member 3 is provided with an action part 34. The elastic member 4 acts elastically between the bottom of the insertion cavity 15 and the action part 34. The elastic member 4 has a rearward elastic force on the action part 34.

[0029] To prevent the elastic element 4 from bending severely during the compression or release process, the action part 34 is provided with a post 35, which protrudes out and the elastic element 4 is sleeved on the post 35.

[0030] To facilitate the rotation and disassembly of the front shell 2 and the rear shell 1, the front shell 2 includes a first shell 2a and a second shell 2b forming a rotating hole 21. The first shell 2a and the second shell 2b can be fixedly connected by screws.

[0031] like Figure 4 , Figure 5 and Figure 8 As shown, a rotation limiting part 16 is provided on the outer edge of the limiting part 12 of the rear shell 1. The rotation limiting part 16 protrudes and the through groove 14 on the rear shell 1 can pass through the rotation limiting part 16, so that when the locking part 31 on the limiting part 3 extends out of the through groove 14, it corresponds to the position of the rotation limiting part 16. This reduces the difficulty of mold manufacturing and production, and also reduces the material consumption required for the molding of the rear shell 1.

[0032] In this embodiment, the front shell 2 is provided with two rotation limiting parts 23 that can cooperate with the rotation limiting part 16. The rotation limiting part 16 rotates between the two rotation limiting parts 23, limiting the rotation angle between the front shell 2 and the rear shell 1. Since the control board for controlling the hedge trimmer is usually installed in the rear shell 1, while the motor that drives the hedge trimmer and the components that detect the temperature and speed of the hedge trimmer are usually installed in the front shell 2, the control board is connected to the motor and the sensors through wires. Limiting the rotation angle between the front shell 2 and the rear shell 1 can also effectively prevent the wires from repeatedly winding when the front shell 2 and the rear shell 1 rotate, improving the safety and service life of the equipment. Preferably, the front shell 2 and the rear shell 1 can be adjusted to a 180° rotation limit.

[0033] like Figures 4-7As shown, a switch button 5 is provided below the rear handle 13 of the rear shell 1, which can be rotated and pressed to trigger. The switch button 5 is provided with a limiting cavity 51 and a limiting block 52, and the limiting component 3 is provided with an action block 36 that cooperates with the limiting cavity 51 or the limiting block 52, so that the pressure of the switch button 5 and the limiting component 3 is mutually restrictive, that is, if one is pressed, the other cannot be pressed, as shown in the following details.

[0034] Scenario 1: For example Figure 6 As shown, the switch button 5 rotates when pressed. The limiting cavity 51 on the switch button 5 accommodates the action block 36 on the limiting member 3, so that the action block 36 is located in the limiting cavity 51, restricting the sliding of the limiting member 3, so that the locking part 31 of the limiting member 3 cannot disengage from the limiting port.

[0035] Scenario 2: For example Figure 7 As shown, the rotation limiting member 3 slides under pressure, and the actuating block 36 of the rotation limiting member 3 slides to the bottom of the rotation limiting block 52 of the rotation limiting member 3. The rotation limiting block 52 abuts against the upper end of the actuating block 36, restricting the rotation of the switch button 5 under pressure.

[0036] The switch button 5 and the rotation limiter 3 are mutually restricted by pressure, so that when the switch button 5 is pressed and the hedge trimmer is working, the front shell 2 and the rear shell 1 cannot be rotated to adjust the angle, or when the rotation limiter 3 is pressed and rotated to adjust the angle between the front shell 2 and the rear shell 1, the switch button 5 cannot be pressed to start the hedge trimmer, thus improving safety during operation or rotation adjustment.
