Abstract
An axial adjustment device includes: a main body; two slide seats disposed in the main body; a first and a second threaded rods disposed in the main body and respectively screwed in the two slide seats; a first transmission gear connected with the first threaded rod; a second transmission gear connected with the second threaded rod; and a fastening member. When the fastening member is switched to a fastening position, the two threaded rods are driven with each other via the two transmission gears. When the fastening member is switched to a releasing position, the two threaded rods can be only independently rotated. The axial adjustment device can control the two slide seats to independently or synchronously move.
Claims20
An axial adjustment device comprising:
- a main body having a front end piece formed at a front end of the main body;
- a first slide seat and a second slide seat disposed in the main body;
- a first threaded rod and a second threaded rod disposed in the main body, each of the two threaded rods having a front end provided with a rod section, the rod sections extending through the front end piece and out of the front end piece;
- a body of the first threaded rod being screwed in the first slide seat for driving the first slide seat to axially move along the first threaded rod;
- a body of the second threaded rod being screwed in the second slide seat for driving the second slide seat to axially move along the second threaded rod;
- a first rotary button and a second rotary button respectively disposed at front ends of the rod sections of the two threaded rods;
- a first transmission gear and a second transmission gear, the second transmission gear being fixedly disposed on the rod section of the second threaded rod;
- the first transmission gear being connected with the rod section of the first threaded rod;
- and
- a fastening member deposed at a front end of the axial adjustment device and operable between a fastening position and a releasing position, when the fastening member is positioned in the fastening position, the two threaded rods being driven with each other via the two transmission gears;
- when the fastening member is positioned in the releasing position, the two threaded rods being driven to rotate independently.
An axial adjustment device comprising:
- a front end piece and a rear end piece;
- a first slide seat and a second slide seat disposed between the two end pieces;
- a first threaded rod and a second threaded rod disposed between the two end pieces, each of the two threaded rods having a front end provided with a rod section, the rod sections extending through the front end piece and out of the front end piece;
- a body of the first threaded rod being screwed in the first slide seat;
- a body of the second threaded rod being screwed in the second slide seat;
- a first rotary button and a second rotary button respectively disposed at front ends of the two threaded rods;
- a first transmission gear and a second transmission gear, the second transmission gear being fixedly disposed on the rod section of the second threaded rod;
- the first transmission gear being disposed on the rod section of the first threaded rod and freely rotatable on the rod section of the first threaded rod and always engaged with the second transmission gear;
- a fastening member disposed between the first threaded rod and the first gear and operable between a fastening position and a releasing position, when the fastening member is positioned in the fastening position, the first transmission gear being fastened to the first threaded rod by the fastening member, whereby the first transmission gear and the first threaded rod are synchronously rotatable and the two threaded rods are driven with each other via the two transmission gears;
- when the fastening member is positioned in the releasing position, the fastening member releasing the first transmission gear from the first threaded rod;
- and
- a lock mechanism disposed in the front end piece, the lock mechanism serving to hold or release the two threaded rods.
