As a kind of preferred version, described in set groove and be positioned on the leading flank of vertical supporting rod, the left and right side of vertical supporting rod is run through respectively at the two ends, left and right of setting groove.
As a kind of preferred version, described in set groove the degree of depth be half of vertical supporting rod thickness.
As a kind of preferred version, described in set groove and be at least two, accordingly, at least extend the end of this foot-operated cross bar two embedded blocks, embedded block is with to set groove suitable and embed respectively corresponding setting in groove and fix.
As a kind of preferred version, the end of described foot-operated cross bar is fixedly connected with vertical supporting rod by screw or nail.
As a kind of preferred version, the end of described foot-operated cross bar is provided with viscose glue with setting on the bonding surface of groove, and the end of foot-operated cross bar is fixedly connected with vertical supporting rod by viscose glue.
As a kind of preferred version, described two vertical supporting rods and a plurality of foot-operated cross bar are wood materials.
As a kind of preferred version, described two vertical supporting rods and a plurality of foot-operated cross bar are square strip shape body.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:
By being concaved with and setting groove on the leading flank of each vertical supporting rod, coordinate the two ends utilize each foot-operated cross bar and to set groove suitable and be embedded in respectively corresponding setting in groove and fix, so guaranteeing that vertical supporting rod has under the prerequisite of better structural strength, make foot-operated cross bar to obtain better and to support at vertical direction, thereby make the structure of ladder more solid and reliable, product is also more durable.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.

20, foot-operated cross bar 21, embedded block.
The specific embodiment
Please refer to shown in Fig. 1 and Fig. 2, the concrete structure that it has demonstrated first preferred embodiment of the utility model, includes two vertical supporting rods 10 and a plurality of foot-operated cross bar 20.
In the present embodiment, this two vertical supporting rod 10 and a plurality of foot-operated cross bar 20 are wood materials, and this two vertical supporting rod 10 and a plurality of foot-operated cross bar 20 are square strip shape body, and material and the shape of vertical supporting rod 10 and foot-operated cross bar 20 are not limited to.
Wherein, this two vertical supporting rod 10 is between left and right every setting, and the plurality of foot-operated cross bar 20 is intervally arranged up and down, and the two ends of each foot-operated cross bar 20 are fixedly connected with two vertical supporting rods 10 respectively; And on the leading flank of each vertical supporting rod 10, be concaved with and set groove 11, the two ends of each foot-operated cross bar 20 with set groove 11 suitable and be embedded in respectively corresponding set in groove 11 fixing.Particularly, in the present embodiment, this is set groove 11 and is positioned on the leading flank of vertical supporting rod 10, and the left and right side of vertical supporting rod 10 is run through respectively at the two ends, left and right of setting groove 11, and this degree of depth of setting groove 11 be vertical supporting rod 10 thickness half; And, the end of this foot-operated cross bar 20 is fixedly connected with vertical supporting rod 10 by screw or nail (not shown), or, the end of this foot-operated cross bar 20 is provided with viscose glue (not shown) with setting on the bonding surface of groove 11, the end of foot-operated cross bar 20 is fixedly connected with vertical supporting rod 10 by viscose glue, and foot-operated cross bar 20 will not limit to the fixed form of vertical supporting rod 10.
