It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0032] The present invention will now be further described with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1 — Figure 3 As shown, a special electric shear for fruit tree fruiting branches includes a support rod 2, a stationary blade 4 and a moving blade 5 that works with the stationary blade 4 to cut branches on the upper part of the support rod 2, the moving blade 5 is connected to a drive device 7 that drives it to swing through a drive rod 53, and a fruit basket 3 is provided at the lower part of the stationary blade 4.

[0035] In this embodiment, the support rod 2 is an aluminum alloy rod, which is lightweight, structurally stable, and not easily deformed, allowing it to be easily extended to a high position. Then, with the combined action of the moving blade 5 and the stationary blade 4, the thin, soft fruiting branches on the fruit tree are cut off, achieving the purpose of harvesting the fruit. The fruit basket 3 is used to hold the cut fruits, preventing them from falling directly to the ground and causing damage.

[0036] The moving blade 5 and the stationary blade 4 are connected by a pin 6. The stationary blade 4 has a first blade 42, and the moving blade 5 has a second blade 52 that mates with the first blade 42. The front ends of the first blade 42 and the second blade 52 have multiple notches to facilitate cutting branches. Driven by the drive rod 53, the moving blade 5 can swing around the stationary blade 4 with the pin 6 as the center to cut the branches. The stationary blade 4 has a first pin hole 41 through which the pin 6 passes, and the moving blade 5 has a second pin hole 51 through which the pin 6 passes.

[0037] like Figure 4 As shown, the drive device 7 includes a first fixed base 71 and a motor (not shown in the figure). A first guide rod 741 is provided on the first fixed base 71, and a movable push rod 74 is sleeved on the outer side of the first guide rod 741.

[0038] A power shaft 75 is mounted on the output shaft of the motor. Three rotating rods 751 are evenly distributed on the power shaft 75. A push rod 74 is mounted on a movable push rod 743 that can be intermittently pushed by the rotating rods 751. To increase the contact area between the push rod 743 and the rotating rod 751, a push-pull ball 752 is provided at the end of the rotating rod 751. The push rod 743 is a curved rod, preventing the rotating rod 751 from continuously pushing it. An elastic element 742 is mounted on the first guide rod 741 to push the movable push rod 74 back to its original position. In this embodiment, the elastic element 742 is a spring.

[0039] like Figure 4 and Figure 9 As shown, the driving device 7 also includes a second fixed base 72, in which a transverse groove 721 is formed, and a transverse moving block 722 is disposed in the transverse groove 721. The transverse moving block 722 can move left and right within the transverse groove 721 (i.e., Figure 4 (Up and down direction). The movable push rod 74 is connected to the transverse block 722 through the second link 77. When the movable push rod 74 moves left and right under the action of the push-pull rod 743 or the elastic element 742, it will drive the second link 77 and the transverse block 722 to move left and right synchronously.

[0040] like Figure 4 and Figure 8 As shown, the driving device 7 also includes a third fixed base 73, which has a receiving groove 731. A swing block 732 is provided in the receiving groove 731. The swing block 732 can only swing left and right within the receiving groove 731 and cannot move left and right. A transverse block 722 is connected to the swing block 732 through a first connecting rod 76. The swing block 732 is connected to the driving rod 53. When the transverse block 722 moves left and right, it will drive the first connecting rod 76 and the swing block 732 to swing left and right, which in turn will drive the driving rod 53 and the moving blade 5 to swing, thereby cutting the twig with fruit (or the connection between the end of the fruit and the branch).

[0041] like Figure 4 — Figure 7 As shown in this embodiment, three rotating rods 751 are evenly distributed on the power shaft 75. Therefore, one action cycle can be achieved by rotating the power shaft 75 by 120° (in this embodiment, the power shaft 75 is defined as clockwise rotation).

[0042] Figure 4 The diagram shows the initial position of the drive device 7. At this time, the rotating rod 751 initially compresses the push-pull rod 743, causing the movable push rod 74 to move towards the first fixed seat 71. The elastic element 742 is initially compressed. At this time, the first connecting rod 76 and the drive rod 53 are both in a horizontal state, and the moving blade 5 and the stationary blade 4 are also in a horizontal state. Figure 1 The figure shows the parallel state. The dashed line in the figure represents the rotation trajectory of the rotating rod 751.

[0043] Figure 5 As shown, Figure 4 In this state, the power shaft 75 rotates 30° clockwise. The movable push rod 74 continues to move towards the first fixed seat 71 until it reaches its limit position (because the rotating rod 751 is about to disengage from the push rod 743, it cannot be pushed to move). The elastic element 742 is fully compressed. The transverse block 722 moves upward under the drive of the second connecting rod 77 and the movable push rod 74, causing the first connecting rod 76, the swing block 732, the drive rod 53 and the moving blade 5 to swing downward. The moving blade 5 crosses with the stationary blade 4 to cut the branch.

[0044] Figure 6 As shown, Figure 5 In this state, the power shaft 75 continues to rotate 30° clockwise. The rotating rod 751 disengages from the push-pull rod 743. Under the action of the elastic element 742, the movable push rod 74 makes an initial reset movement away from the first fixed seat 71. The transverse block 722 moves down under the drive of the second connecting rod 77 and the movable push rod 74, causing the first connecting rod 76, the swing block 732, the drive rod 53 and the moving blade 5 to swing upward. The moving blade 5 returns to a horizontal position with the stationary blade 4.

[0045] Figure 7 As shown, Figure 6In this state, the power shaft 75 continues to rotate 30° clockwise. During this process, the rotating rod 751 remains disengaged from the push-pull rod 743. Under the action of the elastic element 742, the movable push rod 74 makes a complete reset movement away from the first fixed seat 71. The transverse block 722 continues to move downward to its limit position under the drive of the second connecting rod 77 and the movable push rod 74 (at this position, the elastic element 742 is no longer able to push it to move further, and the rotating rod 751 is about to contact the push-pull rod 743). The transverse block 722 moves downward under the drive of the second connecting rod 77 and the movable push rod 74, causing the first connecting rod 76, the swing block 732, the drive rod 53, and the moving blade 5 to swing upward. The moving blade 5 and the stationary blade 4 cross in opposite directions (relative to each other). Figure 5 (Regarding the intersections), this allows for the pruning of branches.

[0046] Power shaft 75 Figure 6 After rotating 30° clockwise from this position, it is... Figure 4 As shown, at this point, the power shaft 75 has completed one operation cycle, and the next rotating rod 751 contacts the push-pull rod 743, driving the relevant components to perform the next operation cycle. This embodiment will not be described in detail.

[0047] In this embodiment, in order to ensure that the movement of the push-pull rod 743 is smooth and reliable, the push-pull rod 743 is also connected to a second guide rod 744, and the first fixed base 71 has an opening for the second guide rod 744 to move (not shown in the figure).

[0048] like Figure 1 and Figure 2 As shown, in order to facilitate the storage of this device, a base 1 is provided at the bottom of the support rod 2. The base 1 contains related components such as battery 11, switch 13 and circuit board 12. Wires 14 can be arranged inside the support rod 2. The battery and switch are connected to the motor of the drive device 7 through the wires. When in use, the worker lifts the support rod 2, aligns it with the end of the fruit or the fruiting branch, and turns on the switch. The moving blade 5 can then swing quickly, working in conjunction with the stationary blade 4 to achieve rapid cutting.

[0049] Example 2

[0050] like Figure 10 As shown, in this embodiment, some structures of the device have been simplified. Specifically, the third fixed base 73 and the moving blade 5 are integrated, and the second fixed base 72 and the stationary blade 4 are integrated, eliminating the need for the drive rod 53.

[0051] When the first link 76 swings, the swing block 732 swings, which drives the receiving groove 731, the third fixed seat 73, and the moving blade 5 to swing accordingly, thereby realizing the shearing function.

[0052] The other structures in this embodiment are the same as in Embodiment 1.

[0053] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way.
