The linkage plate 22 is slidably connected inside the first cross frame 21, and its sliding function allows the extension positioning assembly 2 to adjust its position on the slope. By moving the linkage plate 22, the extension length and position of the extension positioning assembly 2 can be changed to adapt to different terrain and protection requirements of the slope. The connecting plate 23 is fixedly connected to the bottom end of the linkage plate 22 and serves as a connection and transmission part to connect the linkage plate 22 with subsequent components such as the embedded column 24 and transmit the sliding action of the linkage plate 22 to the embedded column 24, thereby ensuring effective connection and smooth action transmission between the components inside the extension positioning assembly 2 and allowing the extension positioning assembly 2 to work as a whole. The embedded column 24 is fixedly connected to one end of the outer side of the connecting plate 23 and is mainly used to penetrate into the interior of the slope, thereby transmitting the force of the extension positioning assembly 2 to the interior of the slope to increase the anchoring force inside the slope and prevent the overall sliding of the slope. The threaded column 25 is threadedly connected to the outer side of the connecting column 26, and its threaded structure can facilitate the connection and disconnection with the connecting column 26.

10. An ecological anchoring and protective structure for deep-cut high and steep slopes, according to the construction method of a deep-cut high and steep slope ecological anchoring and protective structure according to claims 1-9, characterized in that; The specific steps are as follows: S1. First, the side plates (11), top plate (12) and bottom support net (13) in the edge protection assembly (1) together form a basic protection frame of the slope, the side plates (11) resist the lateral pressure of the slope soil, the top plate (12) prevents the soil and rocks at the top of the slope from falling, and the bottom support net (13) supports the loose soil at the bottom of the slope; S2. Then, the extended positioning assembly (2) is fixed to the edge protection assembly (1) through the first cross frame (21), and the linkage plate (22) slides inside the first cross frame (21), thereby driving the connecting plate (23), the embedded column (24), the threaded column (25) and the connecting column (26) to move as a whole, so as to adjust the position of the extended positioning assembly (2) on the slope. By screwing the threaded column (25) and the connecting column (26), the anchoring depth of the embedded column (24) can be changed, thereby increasing the anchoring force inside the slope and preventing the slope from sliding as a whole. S3. Then, the outer side of the extended positioning component (2) is rotatably connected to the fixed component (3), and the outer column (31) is rotatably connected to the connecting column (26). The angle can be adjusted according to the unevenness of the slope surface, so that the fixed component (3) can better fit the slope. The retracted column (33) can move in the expansion slot (32) outside the outer column (31) and achieve position fixation through the cooperation of the clamping slot (34) and the expansion slot (32). The extension length of the fixed component (3) is adjusted, and the nail column (35) can penetrate deep into the slope to further enhance the anchoring effect of the slope. S4. When an abnormality occurs on the slope, the trigger assembly (4) starts to work. The top column (41) is fixedly connected to the top of the linkage plate (22). When the linkage plate (22) moves, the top column (41) is driven to move. The spring (42) is fixedly connected to the outside of the top column (41) and is connected to the push plate (43) to provide elastic force. The push plate (43) contacts the trigger plate (44). The trigger plate (44) is slidably connected to the inside of the side plate (11). When an abnormality occurs on the slope, the trigger plate (44) is moved by external forces such as soil, pushing the push plate (43) to move under the action of the spring (42), thereby triggering the emergency response of the overall protective structure. S5. Finally, the pressure trigger (53) is triggered by the pressure of the trigger plate (44) to trigger the alarm, converting the physical pressure signal into an electrical signal to start the warning device and send out a warning signal. When the pressure trigger (53) is under pressure, the pressure trigger (53) transfers the force to the trigger column (54), and then drives the pressure plate (55) to press downward and transfer it to the connecting plate (23), achieving simple support and providing a support for maintenance personnel to perform maintenance.
