[0048] Example 2

[0049] The difference between this embodiment and embodiment 1 is that the screw rod 6 and the slide bar 7 are replaced by an electric push rod, which can drive the hinged rod 8 to move, but the output end of the electric push rod needs to withstand the offset force generated by the hinged rod 8 and the connecting plate 9.
