Abstract
A hand-operated planer provided with both a fixed workbench and a lifting mechanism with a locking function is combined with a hand-operated planer, which includes a base, a movable workbench, a fixed workbench and a lifting mechanism. The lifting mechanism is composed of a connecting seat, a position-limiting member, an operating rod and a positioning block. When the handle of the operating rod is moved, the operating rod will actuate the position-limiting block of the position-limiting member to operate and drive the driven plate of the connecting seat to rotate via transmission of the connecting rod and thus, the movable workbench assembled above the axis of the connecting seat can be adjusted in height.
