[0054] The top end of the support column 302 abuts against the step of the step portion, so that the support column 302 can well support the threaded cylinder 303. At the same time, the limiting nail 303a cooperates with the annular groove 302a to ensure that the threaded cylinder 303 and the support column 302 are not separated.

[0055] In one embodiment, the scissor lift assembly includes: a first connecting rod 6 , a second connecting rod 7 and a hydraulic telescopic member 8 .

[0056] The bottom end of the first connecting rod 6 is rotatably mounted on the platform plate 4, the top end of the first connecting rod 6 is slidably connected to the bottom of the working platform 9, the top end of the second connecting rod 7 is rotatably mounted on the bottom of the working platform 9, the bottom end of the second connecting rod 7 is slidably connected to the platform plate 4, the first end of the hydraulic telescopic component 8 is hinged to the platform plate 4, the second end of the hydraulic telescopic component 8 is hinged to the first connecting rod 6, and the first connecting rod 6 and the second connecting rod 7 are also hinged.
