[0023] Embodiment 1
[0024] Please refer to Figure 1, the present utility model provides a technical solution: a garden tree pruning mechanical device, comprising: a first connecting rod 1 and a second connecting rod 2. One end of the first connecting rod 1 is sleeved with a connecting cylinder 12, and the other end of the first connecting rod 1 is provided with a driving device 6 which is used to provide the main power for the device. A hand-holding device 5 is arranged between the driving device 6 and the connecting cylinder 12. The hand-holding device 5 can be held with one hand to ensure stability during the working process. The first connecting rod 1 and the second connecting rod 2 are connected through the connecting cylinder 12. One end of the connecting cylinder 12 is sleeved on the first connecting pipe, and the other end of the connecting cylinder 12 is sleeved on the second connecting cylinder 12. A first fixing button 11 is arranged on the connecting cylinder 12. The fixing button is used to fix the second connecting rod 2 so that it can slightly expand and contract or be removed within the connecting cylinder 12. A rotating device 10 is arranged below the second connecting rod 2. The rotating device 10 is used to connect and support the support device 9 so that it can rotate and fold. A support device 9 is arranged on the rotating device 10. The support device 9 is used for support and can be inserted into the ground to ensure labor saving on the basis of being able to prune. A fixing device 8 is arranged on the lower surface of the connecting cylinder 12. The fixing device 8 is used to fix the support device 9 so that it can be folded and fixed below the connecting cylinder 12 when not in use. One end of the second connecting rod 2 is provided with a connecting block 3. The connecting block 3 is used to install a saw 4. The saw 4 is fixedly connected to the connecting block 3 by screws. The saw 4 will move along with the movement of the connecting block 3.
[0025] During actual use, the support can be carried out by unfolding the support device 9. When the support is not needed, the support device 9 can be rotated through the rotating device 10. The support device 9 can be fixed on the fixing device 8. The overall length can be adjusted by adjusting the first fixing button 11 so that it can be used flexibly according to environmental changes, thereby achieving the purpose of labor saving and stability.
[0026] Embodiment Two
[0027] Please refer to Figures 1 - 3 , on the basis of Embodiment One, the support device 9 includes a support main rod 13 and a support sub-rod 14. A rotating shaft 16 is fixedly connected to the support main rod 13. The rotating shaft 16 enables the support main rod 13 to rotate relative to the second connecting rod 2. The support main rod 13 is connected to the rotating device 10 through the rotating shaft 16. The rotation of the support main rod 13 can drive the entire support device 9 to rotate. The support sub-rod 14 extends into the support main rod 13 and is slidably connected thereto. The support sub-rod 14 can be extended, contracted and fixed as needed.
[0028] The fixing device 8 includes a fixing block 17, a telescopic rod 20, a spring 21 and a handle 22. The fixing block 17 is fixedly installed directly below the connecting cylinder 12. The fixing block 17 is used to fix the folded support device 9. A through hole 19 is formed in one side wall of the fixing block 17. The through hole 19 is used to set the telescopic rod 20 so as to clamp the main support rod 13 and the auxiliary support rod 14. The telescopic rod 20 extends into the through hole 19 and is slidably connected thereto. The handle 22 is fixedly installed at one end of the telescopic rod 20. The handle 22 is provided for pulling the telescopic rod 20. The spring 21 is sleeved on the telescopic rod 20. The spring 21 enables the telescopic rod 20 to automatically clamp the auxiliary support rod 14. The spring 21 is always in a contracted state. An arc-shaped groove 18 is formed in the lower surface of the fixing block 17. The arc-shaped groove 18 is used to store the auxiliary support rod 14. When the auxiliary rod is inserted into the arc-shaped groove 18, under the action of the spring 21, the telescopic rod 20 clamps it. Among the two side walls of the arc-shaped groove 18, the side where the through hole 19 is provided is longer.
[0029] During use, the telescopic rod 20 can be driven to move by pulling the handle 22. When the handle 22 is pulled outwards, the telescopic rod 20 will not block the arc-shaped groove 18. At this time, the auxiliary support rod 14 can be inserted into the arc-shaped groove 18. Then the handle 22 is released. Under the action of the spring 21, the telescopic rod 20 will automatically block on the arc-shaped groove 18. In this way, the auxiliary support rod 14 can be effectively clamped in the arc-shaped groove 18. Even during movement, the auxiliary support rod 14 will not fall off the fixing block 17.
[0030] Embodiment Three
[0031] Please refer to Figure 1 and Figure 4 , on the basis of Embodiment Two, the hand-held device 5 includes a support frame 23. The support frame 23 is used to support the second handle 26. The second handle 26 is provided on the support frame 23. The second handle 26 is used to lift the device to ensure its convenient lifting. A fixing shell 25 is provided in the middle of the support frame 23. The fixing shell 25 can fix the support frame 23 on the first connecting rod 1. The fixing shell 25 is divided into two halves, and the two halves of the fixing shell 25 are connected by a capless screw. On both sides of the bottom of the support frame 23, there are provided latching rods 24. The latching rods can extend out or retract into the support frame 23. When extended, the extended part can be latched on some objects, such as a stone bracket, etc., and even can be latched on the thigh. Both of the two latching rods 24 extend into the support frame 23 and are slidably connected thereto.
[0032] In actual use, the support device 9 can be expanded for support. When support is not needed, the support device 9 can be rotated by the rotating device 10. The support device 9 can be fixed on the fixing device 8, and the overall length can be adjusted by adjusting the first fixing knob 11, so that it can be used flexibly according to environmental changes, thus achieving the purpose of saving effort and ensuring stability. When the support device 9 needs to be retracted, the telescopic rod 20 can be driven by pulling the handle 22. When the handle 22 is pulled outwards, the telescopic rod 20 will not block the arc-shaped groove 18. At this time, the support sub-rod 14 can be inserted into the arc-shaped groove 18. Then, the handle 22 is released. Under the action of the spring 21, the telescopic rod 20 will automatically block on the arc-shaped groove 18. In this way, the support sub-rod 14 can be effectively clamped in the arc-shaped groove 18. Even during movement, the support sub-rod 14 will not fall off the fixing block 17. The setting of the support frame 23 and the hand-held device 5 makes it convenient to use and easy to lift during use, and at the same time provides power for the cutting of the entire device.
