The second rotating shaft 5, the first cutting head 6, and the second cutting head 7 are rotated synchronously by rotating the rotating seat 4, that is, the first cutting head 6 and the second cutting head are rotated synchronously. 7. The direction of the blade can be adjusted. The second blade head 7 rotates relative to the first blade head 6 to achieve pruning of garden trees. A rack 9 is provided in the top seat 2 for movement in the vertical direction. A gear 8 is fixedly installed on the first rotating shaft 3, and the rack 9 is meshed with the side wall of the gear 8. The rotation of the gear 8 is achieved by the rack 9 moving in the vertical direction, thereby achieving the synchronous rotation adjustment of the first rotating shaft 3, the rotating seat 4, the second rotating shaft 5, the first blade head 6, and the second blade head 7. The bottom end of the rack 9 passes through the main rod 1 downward and is fixedly installed with a connecting piece 10. The inner cavity of the connecting piece 10 is provided with a driving component for driving the connecting piece 10 to move in the vertical direction, and the rack 9 is prompted to move in the vertical direction by the driving component; mainly refer to Figure 6 As shown, the driving component includes a moving rod 11 fixed and vertically installed at the bottom end of the connecting piece 10, and a fixing plate 12 is fixedly installed at the bottom end of the moving rod 11, and a lead screw 15 passes through and is threadedly connected to the fixing plate 12, and a limit rod 16 is vertically passed through the fixing plate 12, and the lead screw 15 and the limit rod 16 are arranged in parallel. By rotating the lead screw 15, the fixing plate 12 is prompted to move vertically along the limit rod 16 and the lead screw 15, so as to drive the moving rod 11 and the rack 9 at the top of the moving rod 11 to move vertically. Since the rack 9 is meshed with the gear 8, the rack 9 moves vertically, driving the first rotating shaft 3 and the rotating seat 4 to rotate, and with the rotation of the rotating seat 4, the first blade head 6 and the second blade head 7 on the second rotating shaft 5 are rotated synchronously until the free ends of the first blade head 6 and the second blade head 7 are directed towards the garden trees to be pruned.
[0033] As shown in the main reference body 6, a connecting block 13 is fixedly installed on the inner wall of the main rod 1, a fixing seat 14 is fixedly installed on the bottom end of the limit rod 16, and the fixing seat 14 is fixedly connected to the connecting block 13, and the screw 15 is rotatably connected to the fixing seat 14 through a bearing.

By rotating the handwheel 17, the rotation adjustment of the screw 15 can be achieved more quickly.
[0034] Also, see Figure 3As shown, a plurality of first limit seats 18 are fixedly installed on the inner wall of the main rod 1, and the moving rod 11 slides through the first limit seat 18 in the vertical direction. By setting the first limit seat 18 in the inner cavity of the main rod 1, the moving rod 11 can be assisted to move in the vertical direction to avoid the displacement of the moving rod 11.
[0035] Main references Figure 1 and Figure 5 As shown, a sleeve 19 is fixedly provided on the main rod 1, and a second limit seat 20 is fixedly installed on the side wall of the sleeve 19. A push rod 21 is provided through the second limit seat 20 in the vertical direction. The second limit seat 20 can assist the push rod 21 in moving in the vertical direction, thereby ensuring the accuracy and stability of the moving direction of the push rod 21.
[0036] Main references Figure 2 and Figure 4 As shown, a driving pin 22 is fixedly installed on the top of the push rod 21, and a strip seat 23 is fixedly installed on the front side wall of the second cutting head 7. A slide groove 24 is provided on the front side wall of the strip seat 23. The driving pin 22 slides and is embedded in the inner cavity of the slide groove 24. The push rod 21 moves downward along the second limit seat 20, driving the driving pin 22 to move downward synchronously. As the driving pin 22 moves downward, it moves along the inner cavity of the slide groove 24; a pull ring 25 is fixedly installed on the bottom end of the push rod 21, and the pull ring 25 is hollow ring-shaped. By pulling the pull ring 25, the driving of the push rod 21 is more convenient and quick, so that the opening and closing adjustment of the second cutting head 7 relative to the first cutting head 6 can be realized more quickly.
[0037] Other main references Figure 1 As shown, a handle 26 is fixedly mounted on the bottom end of the left side wall of the main pole 1. Holding the handle 26 makes it easier to control the main pole 1, making tree pruning operations more convenient.
[0038] The angles of the first blade head 6 and the second blade head 7 of the present invention can be adjusted, that is, the pruning angles of the first blade head 6 and the second blade head 7 can be flexibly adjusted to accurately prune different parts of the garden, avoid the pruning limitations caused by fixed pruning equipment, and enhance the versatility and flexibility of the equipment; for trees with irregular shapes, whether it is the fine branches on the top, the complex branch distribution on the side, or the hard-to-reach corners at the bottom, the angles can be adjusted according to actual needs to perform just the right pruning, which greatly improves the quality of pruning, makes the garden trees present a more beautiful and natural shape, and can also avoid affecting the healthy growth of trees due to inadequate pruning.
[0039] It is worth noting that in this application, the screw 15 is a self-locking screw 15 available in the existing market. It can self-lock when it stops rotating and will not rotate due to external forces. The above-mentioned existing components will not be described in detail here.
[0040] The working principle of an adjustable garden pruning device in this embodiment is as follows:
[0041] When adjusting the pruning angles of the first blade head 6 and the second blade head 7, the free ends of the first blade head 6 and the second blade head 7 should be directed toward the garden tree to be pruned: by rotating the hand wheel 17 to drive the lead screw 15 to rotate, the fixed plate 12 is caused to move vertically along the limit rod 16 and the lead screw 15, so as to drive the moving rod 11 and the rack 9 at the top of the moving rod 11 to move vertically. Since the rack 9 is meshed with the gear 8, the vertical movement of the rack 9 drives the first rotating shaft 3 and the rotating base 4 to rotate. As the rotating base 4 rotates, the first blade head 6 and the second blade head 7 on the second rotating shaft 5 are synchronously rotated until the free ends of the first blade head 6 and the second blade head 7 are directed toward the garden tree to be pruned.
[0042] By pulling the pull ring 25, the push rod 21 is caused to move downward along the second limit seat 20, driving the driving pin 22 to move downward synchronously. As the driving pin 22 moves downward, it moves along the inner cavity of the slide groove 24, causing the second cutter head 7 to rotate clockwise around the first rotating shaft 3. Since the second cutter head 7 is rotationally connected to the first rotating shaft 3 and the first cutter head 6 is fixedly connected to the first rotating shaft 3, the second cutter head 7 can achieve the purpose of trimming the garden trees between the second cutter head 7 and the first cutter head 6 when it rotates clockwise;
[0043] The pruning angles of the first blade head 6 and the second blade head 7 of the utility model can be flexibly adjusted to accurately prune different parts of the garden, avoiding the pruning limitations caused by fixed pruning equipment, and enhancing the versatility and flexibility of the equipment. By driving the moving rod 11 at the bottom of the equipment to move in the vertical direction, the pruning angles of the first blade head 6 and the second blade head 7 can be adjusted. The adjustment is convenient and quick. The operator can adjust the angle in real time according to the actual pruning situation without stopping the pruning work and operating at the end of the main rod 1, ensuring the accuracy and consistency of the pruning effect and saving time in adjusting the equipment.
[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
