The plurality of fixing grooves 9 are provided in a circular array on one side of the base 1, and one end of the bidirectional threaded rod 10 is fixedly connected to a driving rod 11, and a fixing rod 12 is slidably penetrated on one side of the driving rod 11. One end of the fixing rod 12 penetrates the driving rod 11 and is slidably connected to the inside of one of the fixing grooves 9. The driving rod 11 is T-shaped, and the two connecting columns 3 are respectively threadedly connected to two different threads on the outer surface of the bidirectional threaded rod 10.
