Abstract
An adjustment device with a dual-guiding structure has two worm wheels respectively meshed with two coaxial worm gears. The two worm gears are pivotally and longitudinally fixed by a driving shaft in line. An adjacent end of each worm gear has a locking recess to receive a locking head mounted on the driving shaft. Thereby, the locking head is selectively engaged with the locking recess of one of the worm gears to drive the corresponding worm gear when the locking head on the driving shaft is reciprocated. Then, one worm wheel engaged with the corresponding worm gear is rotated to rewind or release the wires on the work wheel.
Claims4
An adjustment device with a dual-guiding structure comprising:
- two wire-guiding sets, each wire-guiding set having a worm wheel;
- two worm gears coaxially combined together and respectively meshing with the worm wheels on the two wire-guiding sets, wherein each worm gear has an adjacent end and a locking recess defined in the adjacent end;
- and
- a driving shaft axially penetrating the two worm gears and having a locking head mounted on the driving shaft to selectively engage with the locking recess on one of the two worm gears.
