遇上晴天霹雳,我也会头脑空白,手足无力。

It is a wildly eccentric book, with random pages blank or solid blank, others with page skidding down the page edge like a lightning bolt, the plot nearly impossible to follow.
The top part of one inner bolt which matches the blank hole channel of the outer hollow screw is also conical. The rear is provided with a thread and a tetragonal body for holding.
