[0046] Then, the screw rod 27 is rotated by holding the handle 29 to extend it, thereby driving the two cross bars 28 to extend, thereby driving the positioning block 24 to move laterally inward and enter the annular shell 1. The upper and lower sides of the inner edge of the annular shell 1 respectively abut against the vertical surfaces of the upper and lower ends of the steps 25 to position the annular shell 1.
