Nut 11 is arranged in connecting shaft 12, simple structure, but stability maintenance slightly has deficiency.
It is the another embodiment of foot board 6 such as Fig. 8 and Fig. 9, foot board 6 includes two clamping parts 25, two clampings
Portion is connected with fastening assembly, and the fastening assembly can adjust two spacing of clamping part, and fastening assembly includes connecting shaft 26 and suit
In the nut of the end of connecting shaft 26, nut is rotated, the spacing between two clamping parts of regulation makes two clamping parts step up in ridge axle
On.Particularly, the forward surface of two clamping parts is arcwall face, and is coincide with the outer peripheral face of ridge axle, increased holding area, is improved
The stability of foot board.But, structure slightly shows complexity, have impact on efficiency of construction.
Such as Fig. 5, Fig. 6 and Fig. 7, be it is a kind of can fast insert-pull foot board and ridge axle mounting means.The inside of ridge axle 5 is set
Guide channel 21, guide channel 21 sequentially passes through interface 17 and interface 20 from top to bottom, and the guiding of the top of interface 17 is led to
Road is embedded to load onto lock shaft 15, and the guide channel between two interfaces is embedded to load lock shaft 18, the both sides installation side of upper lock shaft 15
Arm 14, screw shell 13 is sleeved on the outer peripheral face of ridge axle 5, and rotation screw shell 13 is realized being moved down on screw shell along ridge axle 5
It is dynamic.Annular groove 22 is set on the medial surface of screw shell 13, and the end of side arm 14 is inlaid in annular groove 22, on such screw shell 13
When lower mobile, by side arm 14, lock shaft 15 is moved up and down along guide channel in drive, needs exist for explanation, on ridge axle 5 also
Gap 16 is set, to realize that side arm 14 is moved up and down.
Lower lock shaft 18 is hidden in the guide channel between two plug-and-pull ports in the presence of elastomeric element, such as elasticity
Part can be helical spring 19, and helical spring 19 is sleeved on the outer peripheral face of lower lock shaft 18, and is inlaid in guide channel.
In addition, the structure of the foot board coordinated with above-mentioned connect-disconnect structure is, such as Fig. 7, including plate body 29 and plug 23, plug
Lockhole 24 is set on 23.
The foot board and the action process of connect-disconnect structure cooperation are：The plug 23 of foot board is inserted in plug-and-pull port, is rotated
Screw sheel 13 is moved down, and upper lock shaft 15 is moved down therewith, and through the lockhole 24 of plug-and-pull port 17 and Qi Nei, upper lock shaft 15 continues
Move down, be resisted against the top surface of lower lock shaft 18, and drive lower lock shaft 18 to move down, until lower lock shaft 18 through plug-and-pull port 20 and its
Interior lockhole, untill guide channel end.So far, a sealed action is completed, foot board is stably fixed to ridge axle
On.When taking out foot board, screw shell is reversely rotated.
The utility model is also further improved to foot board, makes foot board foldable, such as Fig. 8, Fig. 9 and Figure 10, in folder
Installation hinged seat 27 in portion is held, plate body 29 is hinged on hinged seat 27, that is, plate body 29 can be rotated around hinged seat, in order that plate
What body 29 was stablized turns to horizontal level, it is necessary to extend one baffle plate 28 of formation on the holder portion, and Fig. 9 is that plate body 29 is in water
Prosposition is put, and Figure 10 is that plate body 29 is flipped up to vertical position.
