[0031] During use, an auxiliary splicing assembly mechanism can be added through the handrail tube 3, dovetail block 401, limit rod 402 and dovetail groove 301, and the handrail can be quickly assembled according to the actual number of uses by utilizing the mortise and tenon structure and plug-in limit. This not only improves the flexibility of use, but also improves the convenience of subsequent partial disassembly and replacement, thereby reducing maintenance and use costs.

[0032] In order to improve the safety of use, for example, Figure 1 、 Figure 3 As shown, the present invention further includes that the leakage prevention component 5 includes a baffle 501 , both sides of the baffle 501 are connected to the rotating shaft 502 through bolts, and the baffle 501 is rotatably connected to the mounting base 1 through the rotating shaft 502 .

[0034] For example, Figure 1 、 Figure 2 As shown, the utility model also includes that a compression spring 403 is installed on the inner side of the limiting rod 402 in the dovetail block 401 through a spring seat, and a through hole 303 corresponding to the limiting rod 402 is opened on the surface of the handrail tube 3, and the through hole 303 is connected to the dovetail groove 301.

[0035] When in use, the compression spring 403 facilitates the use of elastic force to push the limiting rod 402 to slide outward for insertion and limiting fixation, and the limiting rod 402 is conveniently inserted through the through hole 303 to complete the limiting connection structure.

[0036] For example, Figure 3As shown, the utility model also includes that a coil spring 503 is provided on the outer periphery of the rotating shaft 502, and one end of the coil spring 503 is connected to the rotating shaft 502 by welding, and the other end of the coil spring 503 is connected to the mounting seat 1 through a slot, and a positioning rod 504 is provided on the outer side of the baffle 501 through a reserved hole, and one end of the positioning rod 504 passes through the baffle 501 and is threadedly connected to the support column 2.

[0038] For example, Figure 4 、 Figure 5 As shown, the utility model also includes that the top of the support column 2 is connected to the sleeve 201 by welding, the top of the sleeve 201 is sleeved with the connecting sleeve rod 202, the outer side of the sleeve 201 is threadedly connected with a tightening screw 203 through a reserved threaded hole, and the bottom inside the handrail tube 3 is connected to a rotating seat 302 through a hinge, and the rotating seat 302 is connected to one end of the sleeve rod 202 by a bolt.
