Abstract
An elevating device for the worktable of a manual planer includes at least one base, one movable worktable and one elevating device. The elevating device comprises of a driving shaft, a driven shaft, a rotary base, a connecting rod base, a combining shaft and a spindle. When an operating member of the driving shaft is rotated, a driving gear of the driving shaft drives a first driven gear of the driven shaft to rotate, and a second driven gear of the driven shaft drives a third driven gear of the rotary base to rotate at the same time. Simultaneously, the rotary base is rotated to actuate the connecting rod base to operate, and the movable worktable positioned on the connecting rod base is moved upward or downward and is adjusted in its position.

An elevating device for a worktable of a manual planer comprising:
- a base;
- a movable worktable slidably assembled at one end of said base;
- said elevating device comprises of a driving shaft, a driven shaft, a rotary base, a connecting rod base, an assembly rod, and a spindle;
- said driving shaft axially and pivotally inserted in said base;
- said driving shaft being fixed with an operating member at one end corresponding to said base;
- said driving shaft being provided with a driving gear at one side opposite to said operating member;
- said driven shaft vertically intersecting with said driving shaft;
- said driven shaft being disposed with a first driven gear at one side corresponding to said driving gear of said driving shaft and a second driving gear at another side of said driven shaft;
- said rotary base being provided with a second driven gear to match with said second driving gear of said driven shaft;
- said connecting rod base being secured at a rear side of said rotary base by said assembly rod;
- said spindle axially being inserted through said rotary base and being fixed in said connecting rod base;
- said operating member of said driving shaft being operated to let said driving gear driving said first driven gear of said driven shaft to rotate;
- said second driving gear of said driven shaft being rotated to actuate said second driven gear of said rotary base to rotate;
- said rotary base with said spindle acting as a pivot and being actuated to carry out relative rotation and to actuate said connecting rod base to operate;
- and
- said movable worktable on said connecting rod base being actuated to move upward or downward together with said connecting rod base.
