Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a data distribution demonstration device for statistics comprises a bottom plate 1, wherein two symmetrically distributed telescopic columns 2 are fixedly connected to the top end of the bottom plate 1, a demonstration plate 5 is fixedly connected to the top end of each telescopic column 2, a demonstration groove 6 is arranged on the front surface of the demonstration plate 5, a rotary table 3 is uniformly rotatably installed on the inner wall of the bottom end of the demonstration groove 6 along the length direction of the inner wall, a threaded sleeve 4 is fixedly connected to the top end of the rotary table 3, a threaded column 7 is installed on the inner thread of the threaded sleeve 4, the top end of the threaded column 7 extends to the upper side of the threaded sleeve 4, a fixed rod 11 is fixedly connected to one side of the threaded column 7, which is close to the inside of the demonstration groove 6, a limit block 12 is fixedly connected to one side of the fixed rod 11, which is far away from the threaded column 7, and a limit groove 8 distributed along the, and spacing groove 8 matches with stopper 12, and sliding connection, the universal wheel is all installed in the bottom four corners of bottom plate 1, and is provided with locking mechanism on the universal wheel, stopper 12 with the cross-section of spacing groove 8 all is the setting of T type, the both sides of spacing groove 8 evenly are provided with the scale mark along its direction of height, first connecting rod 9 and second connecting rod 10 are installed in the front of screw thread post 7, and first connecting rod 9 cup joints in the outside of second connecting rod 10, and first connecting rod 9 and second connecting rod 10 sliding connection, the inserted bar is all installed to one side that first connecting rod 9 and second connecting rod 10 are close to demonstration inslot 6 inside, the front of screw thread post 7 is provided with the jack, and the inserted bar matches with the jack.
