Description

Technical Field

[0001] The utility model relates to the technical field of garden tools, in particular to an electric high-branch shears. Background Art

[0002] Pruning fruit trees is an indispensable part of the growth and management of fruit trees, and high-branch shears are important tools for pruning fruit trees. High-branch shears can be roughly divided into manual high-branch shears, electric high-branch shears and pneumatic high-branch shears. Among them, manual high-branch shears are flexible to operate and are not restricted by the environment and tree types. Electric high-branch shears have the advantages of saving time and effort. Pneumatic high-branch shears are more labor-saving and suitable for long-term operation.

[0003] For example, the invention patent with the announcement number CN109924023A discloses an electric high-branch shear, which includes a lithium battery, a self-locking push button and a main switch, a main handle, a telescopic rod, a carrying handle, a movable part of the telescopic rod, a rotating button, a lubricating oil tank, and a chain saw. Among them, the chain saw is fixed to the telescopic rod by a rotating button. The rotating button is installed together with a gasket and a spring. The upper and lower positions of the chain saw can be adjusted by pressing the rotating button. The telescopic rod adopts an L-shaped locking handle at the movable part of the telescopic rod to adjust the length of the telescopic rod. The L-shaped locking handle is convenient for force and is applicable at any time. When there is sweat on the hands, the nut shape will slip. The locking push button and the main switch improve the safety of the operator and avoid the danger of accidentally touching the main switch. A lithium battery is provided at the end of the main handle, which can work continuously for five hours.

[0004] When using the electric high-branch shears, the user needs to hold the main handle and the carrying handle with both hands, and then use the main handle as a fulcrum to lift the carrying handle upward to drive the chain saw upward. Finally, press the main switch on the main handle to perform pruning operations. However, in actual use, due to the heavy weight of the lithium battery and the motor, when the user lifts the high-branch shears, it is easy for the user to slip along the length of the carrying handle, which makes the user more laborious when using it, so there is room for improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an electric high-branch pruner, which can reduce the probability of slipping when the user operates the electric high-branch pruner by using a grip that is perpendicular to the carrying handle, thereby improving operating efficiency and convenience.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] An electric high-branch shear comprises a carrying handle, a grip is vertically arranged on the side of the carrying handle, a sleeve is arranged on the end of the grip close to the carrying handle, a movable opening is opened on the side of the sleeve away from the handle, locking plates extending in a direction away from the handle are arranged on both sides of the movable opening, the two locking plates are arranged opposite to each other and maintain a movable interval, and a locking mechanism is arranged on the locking plates to drive the two locking plates to approach each other so that the sleeve hugs the carrying handle tightly.

[0008] By adopting the above solution, a force point along the length direction of the carrying handle can be formed on the carrying handle through the grip perpendicular to the carrying handle, so that the user is not likely to slip along the length direction of the carrying handle when operating the electric high-branch shears, thereby improving the operating efficiency and convenience. The sleeve mounted on the carrying handle allows the grip to adjust the position and angle on the carrying handle, thereby adapting to the usage habits of different users and being more humane. By driving the two locking plates closer to each other through the locking mechanism, the sleeve can hug the carrying handle tightly to improve the stability of the grip.

[0009] Preferably, the two locking plates are defined as the first locking plate and the second locking plate, and the locking mechanism includes a stud and a nut, one end of the stud is fixed to the plate surface of the second locking plate close to the first locking plate, and the other end is movably inserted into the first locking plate, and the nut is threadedly screwed to the portion of the stud that extends beyond the first locking plate; when the nut is tightened and squeezes the first locking plate, the movable interval between the first locking plate and the second locking plate becomes smaller, so as to drive the sleeve to hold the carrying handle tightly.

[0010] By adopting the above solution, by tightening the nut on the stud, the nut can be pressed against the first locking plate, so that the movable interval between the first locking plate and the second locking plate becomes smaller, thereby driving the sleeve to clamp the carrying handle, thereby completing the locking of the handle. In this way, the efficiency and convenience of locking or unlocking the handle can be improved, and the stability of the handle after being locked can be ensured.

[0011] Preferably, the first locking plate is provided with a through hole for the stud to pass through, and the through hole has an avoidance groove extending in a direction away from the sleeve.

[0012] With the above solution, the through hole allows the stud to pass through the first locking plate, and the avoidance groove allows the stud to have a certain amount of movement space near the through hole, thereby preventing the first locking plate and the second locking plate from being obstructed when being squeezed.

[0013] Preferably, the nut is a quick-release nut.

[0014] By adopting the above solution, the quick-release nut can be disassembled and assembled without tools, further improving operating efficiency and convenience.

[0015] Preferably, an elastic gasket is provided on the inner circumferential surface of the sleeve.

[0016] By adopting the above solution, the elastic gasket can increase the friction between the sleeve and the carrying handle, and further improve the connection stability of the handle.

[0017] Preferably, the outer surface of the carrying handle is frosted.

[0018] By adopting the above solution, the frosted surface can further improve the friction between the sleeve and the carrying handle, thereby further improving the connection stability of the handle.

[0019] Preferably, a locking piece for clamping between fingers is provided at a position of the handle close to the sleeve.

[0020] With the above solution, when the user holds the handle, the gap between the index finger and the middle finger can be clamped on the locking plate, thereby forming a positioning, preventing the hand from leaving the handle, and further improving the firmness of the grip.

[0021] Preferably, a collar is provided at one end of the locking plate close to the handle, and an annular groove for the collar to be rotatably engaged is provided on the outer peripheral surface of the handle.

[0022] By adopting the above scheme, the rotational snap-fit ​​cooperation between the collar and the ring groove can not only realize the axial limitation of the locking plate on the handle, but also realize the circumferential rotation of the locking plate to adapt to different holding postures of the hand on the handle, which is more humane.

[0023] The utility model has significant technical effects due to the adoption of the above technical solutions: through the grip perpendicular to the carrying handle, a force point along the length direction of the carrying handle can be formed on the carrying handle, so that when the user operates the electric high-branch shears, it is not easy to slip along the length direction of the carrying handle, thereby improving the operating efficiency and convenience. The sleeve mounted on the carrying handle allows the grip to adjust the position and angle on the carrying handle, so as to adapt to the usage habits of different users and be more humane. By driving the two locking plates closer to each other through the locking mechanism, the sleeve can hug the carrying handle tightly to improve the stability of the grip.

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, an electric high-branch shear disclosed in this embodiment includes a cylindrical carrying handle 1, a chain saw 17 is arranged at the upper end of the carrying handle 1, and a main handle 18 is arranged at the lower end. A main switch 19 and a lithium battery 20 are arranged on the main handle 18. A grip 2 is vertically arranged on the side of the carrying handle 1, and a circular sleeve 3 is arranged on the end of the grip 2 close to the carrying handle 1. A movable opening 4 is opened on the side of the sleeve 3 away from the grip 2. Both sides of the movable opening 4 are provided with locking plates extending in the direction away from the grip 2. The two locking plates are arranged opposite to each other and maintain a movable interval 5. The locking plates are provided with a locking mechanism 6 that drives the two locking plates to approach so that the sleeve 3 hugs the carrying handle 1. Specifically, the two locking plates are defined as the first locking plate 7 and the second locking plate 8, respectively. The locking mechanism 6 includes a stud 9 and a nut 10. One end of the stud 9 is fixed to the plate surface of the second locking plate 8 close to the first locking plate 7, and the other end is movably inserted into the first locking plate 7. The nut 10 is threadedly screwed to the portion of the stud 9 that exceeds the first locking plate 7. In this embodiment, when the nut 10 is tightened and squeezes the first locking plate 7, the movable interval 5 between the first locking plate 7 and the second locking plate 8 becomes smaller, so as to drive the sleeve 3 to hug the carrying handle 1, thereby completing the locking of the handle 2.

[0031] like Figure 4 As shown, in order to prevent the first locking plate 7 and the second locking plate 8 from being obstructed when clamped together, the first locking plate 7 is provided with a through hole 11 for the stud 9 to pass through, and the through hole 11 extends with an avoidance groove 12 in a direction away from the sleeve 3.

[0032] like Figure 4 As shown, in order to achieve tool-free disassembly and assembly of the nut 10, the nut 10 is a quick-release nut, including but not limited to a butterfly nut, a Yuanbao nut or a ram's horn nut.

[0033] like Figure 4As shown, in order to improve the stability of the handle 2 after locking, the inner circumference of the sleeve 3 is provided with an elastic gasket 13, which is preferably made of a rubber gasket and is fixed to the inner wall of the sleeve 3 by glue. At the same time, the outer surface of the carrying handle 1 is frosted, thereby increasing the friction between the sleeve 3 and the carrying handle 1, thereby making the sleeve 3 and the handle 2 less likely to slip.

[0034] like Figure 4 As shown, in order to improve the connection firmness between the hand and the handle 2, a locking piece 14 for holding between fingers is provided at the position of the handle 2 near the sleeve 3. A collar 15 is provided at one end of the locking piece 14 near the handle 2, and a ring groove 16 for the collar 15 to rotate and engage is provided on the outer peripheral surface of the handle 2, so that the locking piece 14 can rotate around the handle 2, thereby adapting to different holding gestures.

[0035] The specific usage process is as follows:

[0036] Before using the electric high-branch shears, it is necessary to adjust the position of the handle 2 according to the user's own habits. When adjusting, first loosen the nut 10 to release the compression state of the first locking plate 7 and the second locking plate 8, so that the sleeve 3 loosens the carrying handle 1. At this time, the position and angle of the handle 2 on the carrying handle 1 can be adjusted by axially moving and circumferentially rotating the sleeve 3. When the adjustment of the handle 2 is completed, the first locking plate 7 and the second locking plate 8 are clamped again by tightening the nut 10, so that the sleeve 3 can be driven to bite the carrying handle 1 again to complete the fixation of the handle 2.

[0037] In this state, the user can first rotate the locking piece 14 on the grip 2 to a suitable position, then clamp the index finger and the middle finger on the locking piece 14 and hold the grip 2 to complete the grip of the carrying handle 1. At this time, the user can hold the main handle 18 with the other hand, and lift the carrying handle 1 with the main handle 18 as a fulcrum, so that the chain saw 17 on the upper end of the carrying handle 1 moves to the position where work is required. In this process, the grip 2 can form a force point on the carrying handle 1 along the length direction of the carrying handle 1, thereby preventing the user's hand from slipping along the length direction of the carrying handle 1, thereby improving the operating efficiency and convenience.
