[0029] The fixing assembly includes first connecting columns 18 installed on opposite sides of the connecting frame 1, a first connecting groove 20 opened on one side of the fixing frame 3, first fixing grooves 29 and second fixing grooves 30 opened on opposite sides of the connecting frame 1, and fixing columns 25 provided on opposite sides inside the fixing frame 3. The first connecting columns 18 are rotatably fitted in the first connecting groove 20, and the fixing columns 25 cooperate with the first fixing grooves 29 and the second fixing grooves 30.

[0030] An application of one aspect of this embodiment is: when using this tree pruning ladder for garden engineering, the first supports 2 on both sides of the connecting frame 1 are spread apart, thereby driving the second supports 4 on both sides to be spread apart. The fixing rope 31 plays a fixing role. The height of the ladder is adjusted by adjusting the distance between the first supports 2 on both sides and the second supports 4 on both sides to be applicable to trees of different heights. Then, the fixing frames 3 on the other two sides of the connecting frame 1 are spread apart, and the supporting threaded rods 5 at the bottoms of the fixing frames 3 are adjusted to contact the ground for support, so that effective support can be obtained in all four directions of the ladder, and there is no need to lean the ladder against the tree, reducing the situation that the ladder leans against the tree on one side and is prone to left - right shaking and causing falls when construction workers climb.

[0031] On one side of the first support 2 of this embodiment, a plurality of first climbing grooves 6 are provided. On one side of the second support 4, a plurality of second climbing grooves 8 are provided. The first climbing grooves 6 and the second climbing grooves 8 correspond to each other one by one. On the other side of the second support 4, a storage groove 7 is provided. The first support 2 is located in the storage groove 7. On both opposite sides of the second support 4, fixing blocks 10 are installed. On one side of the fixing block 10, a fixing bolt 11 is in threaded cooperation. On both opposite sides of the first support 2, a plurality of first threaded grooves 9 are provided. The fixing bolt 11 is in threaded cooperation in the first threaded grooves 9. By rotating the fixing bolts 11 on both sides counterclockwise to disengage them from the first threaded grooves 9 on both sides of the first support 2, it is convenient to move the first support 2 in the storage groove 7 to adjust the height of the ladder. Then, by rotating the fixing bolts 11 on both sides clockwise to make them in threaded cooperation in the first threaded grooves 9 on both sides of the first support 2, the first support 2 is fixed in the second support 4.

[0032] At the bottom of the second support 4 of this embodiment, a first cushion block 12 is provided. Between the first cushion block 12 and the bottom of the second support 4, a first hinge 13 is provided. At the bottom of the support threaded rod 5, a second cushion block 27 is provided. Between the second cushion block 27 and the bottom of the support threaded rod 5, a second hinge 28 is provided. By providing the first cushion blocks 12 at the bottoms of the two second supports 4 and the second cushion blocks 27 at the bottoms of the two support threaded rods 5, and through the settings of the first hinge 13 and the second hinge 28, it is convenient for the first cushion blocks 12 and the second cushion blocks 27 to contact the ground flatly, ensuring the stability of the placement of the ladder.

[0033] On both sides of the first support 2 of this embodiment, gears 14 are installed. The two gears 14 are meshed with each other. On one side of both first supports 2, second connection grooves 16 are provided. On both opposite sides of the connecting frame 1, second connection columns 15 are installed. The second connection columns 15 are rotationally fitted in the second connection grooves 16. By rotatably fitting the two first supports 2 on the second connection columns 15 on both sides of the connecting frame 1, since the gears 14 on the two first supports 2 are meshed with each other, the two first supports 2 are opened into an isosceles triangle to ensure the stability of the ladder.

[0034] The connecting frame 1 of this embodiment is provided with mounting grooves 17 on both sides of the connecting frame, the first connecting column 18 is installed between the two side walls of the mounting groove 17, the two side walls of the mounting groove 17 are provided with arc grooves 19, the first fixing groove 29 and the second fixing groove 30 are provided at the bottom of the inner wall of the arc groove 19, a sliding groove 21 is provided on one side of the fixing frame 3, and a through groove 22 is provided on both sides of the fixing frame 3. The fixing column 25 slides in the through groove 22, and the through groove 22 is connected to the sliding groove 21. An operating block 23 is installed on one side of the fixing column 25, and the operating block 23 slides in the sliding groove 21. A spring 24 is installed between the operating blocks 23 on both sides. The bottom of the fixing frame 3 is provided with a second threaded groove 26, which supports the threaded rod 5. The groove fits in the second thread groove 26; by toggling the two operating blocks 23 on both sides, the two operating blocks 23 drive the two fixing columns 25 to disengage them from the first fixing groove 29 and the second fixing groove 30, so that the fixing frames 3 on both sides can be rotated to tilt the angle for supporting operations. When the fixing columns 25 are located in the first fixing grooves 29, the fixing frames 3 on both sides are in a vertically fixed state, which is convenient for storing the ladder. When the fixing columns 25 are located in the second fixing grooves 30, the fixing frames 3 on both sides are in an open state for supporting. By rotating the supporting threaded rod 5, the height of the second pad 27 at its bottom can be adjusted to adapt to the height of the first bracket 2 and the second bracket 4 on both sides, so that the second pads 27 on both sides can fit the ground for supporting operations.
