[0002] Garden maintenance refers to the activities of maintaining and managing garden landscapes, including plant care, soil management, pest and disease control, greening projects, irrigation system maintenance, garbage removal, and facility maintenance. Through maintenance, the beauty, cleanliness, and health of the garden can be preserved.

[0003] In the process of garden maintenance, garden ladders are needed to prune tree tops, allowing people to climb to higher places for pruning. However, existing garden ladders are usually one-piece designs, which take up a lot of space, are inconvenient to move, carry, and store, and are restricted in their movement. Summary of the Invention

[0004] The purpose of this utility model is to provide a portable garden ladder for garden maintenance, which takes up little space when stored and is easy to carry.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable garden ladder for garden maintenance is provided, including a lower climbing frame. The lower climbing frame is movably connected to an upper climbing frame via a hinge. Insertion slots are provided at opposite ends of the upper and lower climbing frames. A limiting groove is provided on the outer wall of the upper climbing frame. An insertion plate is provided inside the upper insertion slot, and the bottom of the insertion plate extends into the lower insertion slot. A limiting block is fixedly connected to the upper end of the outer wall of the insertion plate, and the limiting block is located inside the limiting groove. A connecting rod is fixedly connected to the middle of the top of the upper climbing frame. A rotating shaft is provided inside the connecting rod. Driven bevel gears are fixedly connected to both ends of the rotating shaft. A throttle is fixedly connected to the other side of the drive bevel gear. Fixed plates are fixedly connected to the outer walls of both sides of the upper climbing frame. A lead screw is movably connected to the top of the fixed plate. The lead screw is threadedly connected to the limiting block. A driven bevel gear is fixedly connected to the top of the lead screw, and the outer wall of the drive bevel gear meshes with the outer wall of the driven bevel gear.

[0006] Optionally, support plates are fixedly connected to the outer walls of both sides of the upper climbing frame, the lead screw passes through the interior of the support plate, and a lead screw positioning ring is fixedly connected to the upper end of the outer wall of the lead screw, the lead screw positioning ring being located at the upper end of the support plate.

[0007] Optionally, a shaft positioning ring is fixedly connected to the outer walls of both ends of the shaft, and annular grooves are provided on both outer walls of the upper climbing frame, with the shaft positioning ring located inside the annular grooves.

[0008] Optionally, the outer wall of the connecting rod is provided with anti-slip texture, and a footboard is provided between the lower climbing frame and the upper climbing frame, and there are multiple footboards, with anti-slip texture on the top of each footboard.

[0009] Optionally, a rotating plate is movably connected to the bottom inner wall of the lower climbing frame, and the bottom of the rotating plate is provided with anti-slip nails, and the number of anti-slip nails is multiple.

[0010] Optionally, magnetic plates are provided on the back of both the lower and upper climbing frames, and there are two magnetic plates in each case.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In its initial state, the lower and upper climbing frames are folded together, with the insert plate retracted inside the upper climbing frame. At this time, the magnetic plates on the back of the lower and upper climbing frames are attracted to each other, resulting in a folded state and minimal space occupation. To unfold the device, separate the lower and upper climbing frames, keeping them on the same horizontal line. Then, rotate one side of the handle, causing the rotating shaft and the drive bevel gears at both ends to rotate. The driven bevel gears and lead screw meshing with these gears rotate synchronously. As the lead screw rotates, the limiting block moves the insert plate outward from the insert plate slot inside the upper climbing frame, thus entering the insert plate slot inside the lower climbing frame. This fixes the positions of the lower and upper climbing frames, bringing the device to an unfolded state. Place the connecting rod of the upper climbing frame against the tree to be pruned, and step on the rotating plate, causing multiple anti-slip studs at the bottom of the rotating plate to insert into the soil, maintaining the stability of the lower climbing frame's bottom. This device is convenient to carry, occupies little space, and improves stability during use. Attached Figure Description
