    • A manual tool capable of unfolding only one work accessory comprises a handle (11, 21), a first work accessory (12, 22) and a second work accessory (13, 23) that are connected to the handle through a pivot and can be unfolded and folded, and an associated accessory (14, 24). The associated accessory can transform the working state from a folding state to an unfolding state. When the first work accessory and the second work accessory are both folded, the associated accessory does not prevent any work accessory from unfolding; and when one of the two work accessories is unfolded and the other one is folded, the associated accessory prevents the other one from unfolding, so as to ensure that only one work accessory can be unfolded during use, thereby eliminating the safety risk caused by unfolding multiple work accessories at the same time.
