[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-6 The utility model provides a technical solution: a garden pruning device, including a fixed frame 1, a handle 2, a strap 3, a first motor 4, a threaded rod 5, a sliding rod 6, a second motor 7, a bearing 8, a rotating wheel 9, a fixed rotating column 10, a slot cylinder 11, a third motor 12, a gear 13, a left pull rod 14, a right pull rod 15, a spring 16 and an electric saw blade 17;

[0028] When the garden pruning device is in use, Figure 1 、 Figure 2 and Figure 3 As shown, when it is necessary to trim higher or farther shrubs, one hand grasps either side of the handle 2 fixedly connected at the front and rear ends of the fixed frame 1, puts the hand into the inner side of the strap 3, and the other hand holds the bracket at the upper end of the fixed frame 1, so that the fixed frame 1 can be grasped more stably for trimming, and the first motor 4 fixedly connected to the inside of the fixed frame 1 is started to drive the threaded rod 5 fixedly connected to the right end of the first motor 4 to rotate, so that the sliding rod 6 threadedly connected to the outer side of the threaded rod 5 moves to the right. At this time, the front and rear outer sides of the sliding rod 6 inside the fixed frame 1 connected to the card slot slide to the right to limit the sliding rod 6, so that the position of the sliding rod 6 can be moved to trim higher or farther shrubs;

[0029] like Figure 1 、 Figure 2 and Figure 4 As shown, when it is necessary to switch to a different trimming angle, the second motor 7 fixedly connected to the right end of the slide bar 6 is started, driving the rotating wheel 9 to rotate in the bearing 8 fixedly connected to the right end of the second motor 7. At this time, the inner end of the rotating wheel 9 rotates inside the right end of the slide bar 6 to limit the rotating wheel 9. When the rotating wheel 9 rotates, it drives the fixed rotating column 10 fixedly connected to the right end of the rotating wheel 9 to rotate, so that the electric saw blade 17 can be adjusted according to the required trimming angle;

[0030] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, when it is necessary to replace the electric saw blade 17 of a different shape or replace the damaged electric saw blade 17, the third motor 12 fixedly connected to the upper end of the card slot cylinder 11 is started to drive the gear 13 fixedly connected to the lower end of the third motor 12 to rotate. When the gear 13 rotates counterclockwise, the left pull rod 14 engaged with the rear end of the gear 13 moves to the left. At this time, the spring 16 fixedly connected to the outer side of the lower end of the left pull rod 14 is subjected to pressure and deformed, limiting the left pull rod 14. At the same time, the outer side of the lower end of the left pull rod 14 slides to the left inside the card slot cylinder 11, so that the lower end of the left pull rod 14 The outer side is disengaged from the slot connection between the electric saw blade 17, and at the same time, the right pull rod 15 engaged with the front end of the gear 13 moves to the right. At this time, the spring 16 fixedly connected to the outer side of the lower end of the right pull rod 15 is subjected to pressure and deformed, thereby limiting the right pull rod 15. At the same time, the outer side of the lower end of the right pull rod 15 slides to the right inside the slot tube 11, so that the outer side of the lower end of the right pull rod 15 is disengaged from the slot connection between the electric saw blade 17, and the electric saw blade 17 is taken out downward, so that electric saw blades 17 of different shapes can be quickly replaced or damaged electric saw blades 17 can be replaced, saving disassembly time.
