DETAILED DESCRIPTION

In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

As shown in Figures 1-4, a simple forsythia pruning device includes a base frame 1 and a pruning knife 2. A support seat 3 is longitudinally slidably connected to the base frame 1. A rotating component 4 for arbitrarily rotating the pruning knife 2 is provided between the top of the support seat 3 and the pruning knife 2. The pruning knife 2 has a first blade 201 and a second blade 202 hinged to each other. The first blade 201 is fixedly connected to the movable end of the rotating component 4, and a push-pull rod 5 is hinged on the second blade 202.

As shown in Figures 2 and 3, in this embodiment, a fixed axis 6 is provided on both sides of the base frame 1, and a traction rope 7 is wound around the fixed axis 6. One end of the traction rope 7 is fixedly connected to the support seat 3, and the other end of the traction rope 7 is wound with a rotating shaft 8. The rotating shaft 8 is parallel to the fixed axis 6 and is arranged on the base frame 1.

By arranging the fixed shafts 6 on both sides of the base frame 1, the pulling force of the traction rope 7 on the two ends of the support seat 3 is consistent, which is conducive to the stable lifting and lowering of the support column.

In this embodiment, a servo motor 9 is disposed on the base frame 1 , and an output end of the servo motor 9 is coaxially fixedly connected to the rotating shaft 8 .

As shown in Figures 1 and 4, in this embodiment, the rotating component 4 includes a first rotating member 41 and a second rotating member 42, and the two ends of the first rotating member 41 are respectively rotatably connected to the second rotating member 42 and the top of the support seat 3, and the other end of the second rotating member 42 is fixedly connected to the first blade 201, and the rotation centers of the first rotating member 41 and the second rotating member 42 are perpendicular to each other.

As shown in FIGS. 2 and 4 , in this embodiment, a first handle 10 is fixedly mounted on the end of the first blade 201 , a second handle 11 is fixedly mounted on the end of the second blade 202 , and the push-pull rod 5 is hinged to the bottom end of the second handle 11 .

By providing the first handle 10 and the second handle 11, the turning force arm of the second blade 202 during pruning is extended, which saves effort.

In this embodiment, the top of the support seat 3 has a support cavity 12 passing through both ends, and the opening side of the support cavity 12 faces the push-pull rod 5 .

In this embodiment, the push-pull rod 5 is a telescopic rod, which is convenient for satisfying the arm lengths of different users, improving the versatility of trimming, and having a wide range of applications.

As shown in FIGS. 2 and 3 , in this embodiment, a sheath 13 is provided on the base frame 1 , the bottom end of the sheath 13 is open, and the fixed shaft 6 is located inside the sheath 13 .

The sheath 13 can effectively shield dust and blades dropped from the top of the base frame 1, preventing the blades from falling between the traction rope 7 and the fixed shaft 6 and affecting the normal movement of the traction rope 7, thereby ensuring the structural stability of the traction rope 7.

Working principle:

As shown in Figures 2 and 3, first, the servo motor 9 drives the rotating shaft 8 to rotate, driving one end of the traction rope 7 to be gradually retracted into or extended from the rotating shaft 8, so that the support seat 3 moves longitudinally accordingly. When the support seat 3 moves to the target height, the servo motor 9 is stopped, and then the user's arm is inserted into the support cavity 12, which is convenient for stably supporting the user's arm and preventing the arm from being raised for a long time, relieving the arm pain of the staff and reducing the labor intensity. Then, as shown in Figures 2 and 4, by rotating the push-pull rod 5, the first rotating member 41 and the second rotating member 42 are driven to rotate accordingly, and the pruning knife 2 can be smoothly rotated in the three-dimensional space to meet the pruning requirements of the pruning knife 2 at any angle. Finally, the push-pull rod 5 is pulled to make the first blade 201 and the second blade 202 shear each other, so as to achieve smooth cutting of the forsythia, save time and effort, and operate the push-pull rod 5 to simultaneously meet the requirements of multi-angle shearing and pruning, thereby improving pruning efficiency.
