[0027] Reference Figure 1-Figure 5 A garden ladder for garden maintenance comprises a base 1, the top of the base 1 is rotatably connected with a main ladder 2 through a rotating shaft, the inner wall of the main ladder 2 is slidably connected with a secondary ladder 3, a rectangular groove 4 is provided on the side of the main ladder 2, a connecting frame 5 is fixedly connected with the bottom of the main ladder 2, two placement grooves 6 are provided on the top of the connecting frame 5, a slide bar 7 is fixedly connected to the inner wall of the two placement grooves 6, a slide bar 7 is slidably connected to the surface of the slide bar 7 with a slider 8, a reset spring 9 is sleeved on the surface of the slide bar 7, and the end of the reset spring 9 is fixedly connected to the slider 8, and the sides of the main ladder 2 and the secondary ladder 3 are both provided with limiting holes 10, the inner wall of the limiting hole 10 is plugged with a latch 11, and the end of the latch 11 is fixedly connected to the slider 8.

[0028] When the staff member is about to climb up, the ladder 2 is lifted up and the ladder 2 is lowered, and the ladder 2 is lifted up, and the ladder 2 is lifted and the ladder 2 is lowered, the ladder 2 is lifted and the ladder 2 is lowered.

[0029] Reference Figure 2 A handle 12 is fixedly connected to the side of the slider 8 , and the handle 12 is located just above the return spring 9 .

[0030] In the present invention, the handle 12 is provided to increase the contact area of ​​the staff's hand, so that the staff can better pull the handle 12 to drive the slider 8 to move.

[0031] Reference Figure 3A mounting groove 13 is provided at the top of the base 1, and a screw rod 14 is rotatably connected to the inner wall of the mounting groove 13 through a bearing. A threaded block 15 is rotatably connected to the surface of the screw rod 14 through a thread. The top of the threaded block 15 is rotatably connected to a rotating rod 16 through a rotating shaft. A fixing frame 17 is fixedly connected to the bottom of the main ladder 2, and the end of the rotating rod 16 is rotatably connected to the fixing frame 17 through a rotating shaft.

[0032] In the present invention, since the growth angles of the branches of plants that need to be pruned are different, when the staff prunes branches at different angles, they are generally required to adjust the angle on the garden ladder by themselves. However, this operation will involve certain safety risks. Therefore, another staff member can turn the hand wheel clockwise by hand to drive the screw rod 14 to rotate, so that the screw rod 14 drives the threaded block 15 to move, and at the same time, the threaded block 15 drives the rotating rod 16 to rotate through the rotating shaft, and then the rotating rod 16 drives the fixing frame 17 to rotate through the rotating shaft, and simultaneously the fixing frame 17 drives the main ladder 2 to rotate in the base 1 through the rotating shaft, so that the staff can adjust the angle of the garden ladder according to the actual situation, thereby facilitating the staff to prune branches at different angles.

[0033] Reference Figure 3 A guide groove 18 is provided on the side of the mounting groove 13 , and a guide block 19 is slidably connected to the inner wall of the guide groove 18 , and the side of the guide block 19 is fixedly connected to the threaded block 15 .

[0034] In the present invention, the guide groove 18 and the guide block 19 are provided to limit the thread block 15, so as to prevent the screw rod 14 from driving the thread block 15 to flip and affect normal use.

[0036] In the utility model, when the screw rod 14 rotates one circle clockwise, the screw rod 14 drives the driving member 20 to rotate, and the driving member 20 drives the toothed disc 22 to rotate, and then the toothed disc 22 drives the rack 23 and the limit rod 24 to move downward, and finally the limit rod 24 is inserted into the soil to form a positioning, and vice versa, so as to lock the garden ladder and avoid the garden ladder shaking during use, which may cause the staff to fall and cause safety hazards.

[0037] Reference Figure 4 A support rod 21 is fixedly connected to the top of the base 1, and the end of the support rod 21 is rotatably connected to the driving member 20 through a bearing.

[0038] In the utility model, the driving member 20 and the driving member 20 can be supported by the setting of the support rod 21, so that the driving member 20 can drive the toothed disc 22 to rotate later.

[0039] Reference Figure 1-Figure 5 A push handle 25 is fixedly connected to the top of the base 1, and the push handle 25 is symmetrically arranged.

[0040] In the utility model, the push handle 25 is provided to increase the contact area of ​​the hand of the staff, so that it is convenient for subsequent staff to push the garden ladder.

[0041] Reference Figure 1-Figure 5 The side of the base 1 is fixedly connected with a moving wheel 26, and the number of the moving wheels 26 is four.

[0042] In the utility model, by providing the moving wheels 26, it is convenient for workers to push the garden ladder to move, thereby avoiding the need for manual moving of traditional garden ladders, which increases the fatigue intensity of workers.
