[0016] An adjustable support fixture for a movable operating platform, such as Figure 5 As shown, the adjustable support fixture 1 is disposed adjacent to the travel wheel 2 at the bottom end of the movable operating platform frame, and is used to stably support the movable operating platform. Figures 1 to 4As shown, the adjustable support fixing device 1 includes a fixed bracket 101 and an adjustable support 102. The fixed bracket 101 is used to fix the adjustable support 102 on the movable operating platform base 4 through bolts 3. The fixed bracket 101 is a U-shaped frame. The side arm on one side of the U-shaped frame is longer than the side arm on the other side, which is called a long side arm 101-1. The long side arm 101-1 is provided with a plurality of positioning holes 101-2 arranged in an arc shape at intervals on the opening side of the U-shaped frame. Through holes 101-3 are relatively provided on the two side walls of the closed end of the U-shaped frame. One end of the adjustable support is connected to the movable operating platform base 4 through a The support shaft 5 passes through the through holes 101-3 on the two side walls and is rotatably connected to the U-shaped frame. A through hole 101-4 is provided on the adjustable support corresponding to the multiple positioning holes 101-2 on the long side arm. The adjustable support 102 is rotated to make the through hole 101-4 face one positioning hole 101-2 according to the use state, and then a positioning rod 6 is inserted into the through hole 101-4 and the positioning hole 101-2 to position the adjustable support vertically downward, horizontally or obliquely upward; one end of the positioning rod 6 has a bent handle 601, and the bent handle 601 is hinged to the positioning rod 6 so as to be Figure 3 Fold as shown.
