[0049] The stepped clamp 28 is adapted to the limiting screw 27 through the threaded slide 26 and is then slidably connected to the inner end surface of the fixed clamp 23, and the threaded slide 26 drives the stepped clamp 28 to fix the handrail beam 6 to the inner wall of the fixed clamp 23.

Figure 7 As shown, if it is necessary to adjust the inclination of the two groups of handrail beams 6, the reduction motor 222 can be started at this time, and the reduction motor 222 can drive the transmission worm gear 224 to rotate through the transmission worm 225, and the transmission worm gear 224 can drive the support card plate 21 to accurately flip through the support card seat 223, so as to facilitate the subsequent adjustment of the inclination angle of the two groups of handrail beams 6 and the footrest beams 5. Figure 1 and Fig.11 When loading the foot beam 5, in the initial state, the wide cylinder 43 can drive the two sets of fixed clamp arms 42 and the limit clamp 41 to be in an open and closed state. When the foot beam 5 is introduced into the limit clamp 41 in the lifting module, the wide cylinder 43 can drive the two sets of limit clamps 41 to clamp and limit the foot beam 5 through the fixed clamp arms 42. Figure 2 and Figure 3After the footrest beam 5 and the handrail beam 6 are limited, the assembly operation begins. First, the staff can start the servo motor 7. At this time, the servo motor 7 can synchronously drive the multiple sets of ball screws 8 to rotate through the limit clamping shaft 10. The multiple sets of ball screws 8 can synchronously drive the multiple sets of ball slides 45 to perform synchronous and precise thread displacement inside the support base 1, so that the multiple sets of clamping devices 4 can drive the footrest beam 5 to synchronously move forward and backward until it is aligned with the reserved holes on the outside of the two sets of handrail beams 6. Then the stepper motor 9 is started, and the stepper motor 9 can synchronously drive the two sets of thread guide seats 226 to perform centripetal displacement through the bidirectional screw 11, so that the two sets of thread guide seats 226 can synchronously drive the support card 21 and the handrail beam 6 is displaced toward the multiple groups of footrest beams 5 until the footrest beams 5 are completely plugged and assembled with the handrail beams 6 through the reserved holes, and then the support motor 33 can synchronously drive the two groups of guide screws 35 to rotate through the second synchronous pulley 32 and the second synchronous belt 34, and the two groups of guide screws 35 can be threadedly connected with the threaded slide 311, thereby driving the fixed slide 31 to move forward until the multiple groups of drill bits 310 at the bottom of the fixed slide 31 are opposite to the handrail beams 6 to be punched, at this time, the guide cylinder 37 can drive the alignment slide 38 to move downward, and at the same time, the multiple groups of drilling motors 39 can drive the drill bit 310 to rotate at a high speed until the drilling of the footrest beams 5 and the handrail beams 6 is completed, so as to facilitate the positioning and assembly of the subsequent connecting parts.
