摘要： A power extension cord socket includes a first socket device and a control device. The first socket device has plural AC power sockets and AC power switches, and each AC power socket is provided for plugging an external load to forward mains electricity, and each AC power switch is connected to the respective AC power socket for controlling the open circuit or closed circuit of the AC power socket. The control device is coupled to the mains electricity and electrically connected to the first socket device. The control device has a leakage detection processor and a leakage power-off switch and uses the leakage detection processor to detect a current usage status of the first socket device, and turns on the leakage power-off switch in an abnormal status to stop each AC power socket from forwarding the mains electricity to the load.

摘要： A reversible ratchet wrench includes a driving member received in a receiving space of a body, rotatable about a rotational axis relative to the body, and having an annular toothed portion. First and second pawls are aligned with each other along an axis parallel to the rotational axis and are alternatively disposed. The first and second pawls are received in a compartment in the body. One of the first and second pawls selectively meshes with the driving member. Each of the first and second pawls includes a ratcheting portion. The ratcheting portions selectively mesh with the annular toothed portion. A control member is pivotably received in the compartment. An end of the control member presses against the first and second pawls when the reversible ratchet wrench is switched between first and second positions. The control member can be actuated to move the first and second pawls.
