The above-mentioned technical purpose of the utility model technical scheme is that：A kind of scalable stair shield
Column, including column, affixed pedestal and the handrail affixed with column top, the column include being fixed on the bottom of column
The connecting rod one of pedestal slidably connects connecting rod two in the connecting rod one, is additionally provided with the locking member for locking connecting rod two and connecting rod one.
Through the above technical solutions, connecting rod two is skidded off connecting rod one, and then increase the height of column, recycles locking member will
Connecting rod one is fixed with the position after the sliding of connecting rod two, and for height, higher people gets a grip on the rail, and it is curved to reduce the higher people of height
The possibility of waist handrail.
The utility model is further arranged to：One top of the connecting rod offers opening, and the inside of the connecting rod one opens up
There are the sliding slot that connection is open, the sliding in the connecting rod one along the sliding slot of the connecting rod two.
Through the above technical solutions, connecting rod two slides in the sliding slot of connecting rod one so that connecting rod two is slided along the direction of sliding slot
Go out, reduces column and fix the possibility to shift with handrail.
The utility model is further arranged to：The bottom protrusion of the connecting rod two has the anticreep for preventing connecting rod two from skidding off opening
Portion.
Through the above technical solutions, the bottom of connecting rod two can be terminated in the lower section of opening by anti-delinking part, and then prevent connecting rod
Two slip out of institute sliding slot.
The utility model is further arranged to：The locking member is handle, and the side of the connecting rod one offers threaded hole,
The handle is fixed in the threaded hole.
Through the above technical solutions, handle personnel easy to operation hold and turn.
The utility model is further arranged to：What the connecting rod two closed on the anti-delinking part offers fixing groove, institute on one side
Fixing groove is stated to abut with one end of the handle.
Through the above technical solutions, being abutted with one end of handle using fixing groove, and then make the cunning of connecting rod one and connecting rod two
Dynamic position is fixed, and the height of fixed handrail, convenient for height, higher people can get a grip on the rail.
The utility model is further arranged to：The cross bar for stablizing the column is connected between the column.
Through the above technical solutions, cross bar further increases the stability between column, ensure the safety of user.
In conclusion the utility model has the advantages that：
1, two people grip the both ends of handrail, and handrail is up lifted, when lifting to desired height, handrail lower surface is affixed
The sliding position of column is fixed, i.e., is screwed into handle end in the fixing groove of connecting rod two, then successively from both ends to middle part by handle
End is screwed into fixing groove, and column and handrail is made to reduce the possibility deformed upon, and then the height of handrail is made to increase to adapt to
The higher people of height gets a grip on the rail；
2, in the corner of handrail, set handrail to arc transition, can prevent user because handrail do not have transition or its
The hand of user empties above column caused by his transition, reduces the balance of user.

Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment：A kind of scalable stair railing, as shown in Figure 1, the handrail being fixedly connected including column 2,2 top of column
4 and column 2 the cross bar 5 that passes through of bottom, the part for being pierced by cross bar 5 is fixedly connected with pedestal 1, and pedestal 1 is fixed on stair.
With reference to shown in Fig. 2 and Fig. 3, column 2 includes connecting rod 1 and connecting rod 2 22, and the bottom of connecting rod 1 and pedestal 1 are solid
Fixed connection, the top of connecting rod 1 offer opening 223, and sliding slot 224, sliding slot 224 and opening 223 are offered inside connecting rod 1
Connection, the bottom of connecting rod 2 22 are provided with anti-delinking part 221, the width of sliding slot 224 be open 223 width and anti-delinking part 221 it
With, when the bottom of connecting rod 2 22 slides at opening 223, anti-delinking part 221 and conflict at opening 223, and then make connecting rod 2 22
Bottom terminates in the lower section of opening 223, to prevent connecting rod 2 22 from being slipped out of sliding slot 224.
With reference to shown in Fig. 3, the fixing groove 222 of strip, the side wall of connecting rod 1 are offered on the side of connecting rod 2 22
