It is located at the bottom of the pole and is mainly used to bear the downward pressure of the pole. The role of the cement chassis is mainly reflected in two aspects: First, it stabilizes the pole and prevents it from sinking; during the construction process, the foundation pit needs to be dug first, and then the chassis is placed in, and its weight and shape characteristics ensure the stability and verticality of the pole. Second, it is connected to the bottom of the pole, so that even if the pole is high, it will not tilt or collapse.

One end of the spring 4 is fixedly connected to the inner wall of the slide groove 2, and the other end of the spring 4 abuts against the sliding sleeve 5.

[0023] like Figure 2 and Figure 4As shown, a mounting frame 15 is provided inside the mounting sleeve 12, and a fixing rod 13 is fixedly connected to the inner wall of the mounting frame 15 in a penetrating manner. Both ends of the fixing rod 13 are respectively fixedly connected to the inner wall of the mounting sleeve 12, and the inner wall of the mounting frame 15 is symmetrically structured and rotatably connected to two rotating shafts 14, and both ends of the mounting frame 15 are rotatably connected to a first pulley 16.

[0024] like Figure 4 As shown, a fixing plate 17 is fixedly connected to the inner wall of the mounting sleeve 12, an electric push rod 18 is fixedly connected to the inner wall of the fixing plate 17, a control switch 19 is fixedly connected to the outer wall of the mounting sleeve 12, and the control switch 19 is used to control the start and stop of the electric push rod 18. A bracket 20 is fixedly connected to the top of the electric push rod 18, and the inner wall of the bracket 20 is symmetrically structured and rotatably connected to two second pulleys 21.
