A pair of pruning shears has two bodies pivotally mounted together with a pivot, a spring connected between the bodies, and a lock device arranged near the pivot. The lock device comprises a step hole defined in one of the bodies near the pivot, a locking hole defined in the other body, a latch post moveably mounted in the step hole, a biasing member to support the latch post, and a knob. The knob is rotatably mounted on the body with the step hole. The knob has a bottom abutting the latch post and a cavity defined in the bottom. When the bodies are pushed toward to each other, the step hole will align with the locking hole. The latch post can be pushed to engage with the locking hole by the bottom of the knob. This can provide a secure positioning effect to the latch post. The latch post will not escape from the locking hole when the pruning shears bump with another object.

Disclosed are driving circuit and method which are used in an Organic Light Emitting Diode (OLED), and more specifically to a driving circuit of an organic light emitting diode and a driving method thereof which use a thin film transistor (TFT) as an active device.
