Abstract
A chuck device includes a connecting mechanism and a locking mechanism, where the locking mechanism includes a driving portion, a first locking portion and a second locking portion, where the first locking portion at least partially extends into a first receiving portion; and the second locking portion is rotatably connected to the first receiving portion through a second shaft. When the locking mechanism is in a first state, the second locking portion rotates along a first direction to drive a sleeve to bias against a biasing element and release a limitation on the first locking portion.
Claims21
A chuck device for clamping a working accessory, comprising:
- a connecting mechanism formed with a first receiving portion to receive the working accessory and extending along a first axis;
- and
- a locking mechanism, connected to the connecting mechanism and used for retaining the working accessory in the first receiving portion, comprising a driving portion, comprising a biasing element and a sleeve that supports the biasing element, a first locking portion at least partially extending into the first receiving portion, and a second locking portion rotatably connected to the first receiving portion through a second shaft, wherein, in a first state of the locking mechanism, the second locking portion rotates about an axis of the second shaft along a first direction to drive the sleeve to bias against the biasing element and the second locking portion drives the sleeve to release a limitation on the first locking portion.
A chuck device for clamping a working accessory, comprising:
- a connecting mechanism formed with a first receiving portion used for receiving the working accessory and extending along a first axis;
- and
- a locking mechanism, connected to the connecting mechanism and used for retaining the working accessory in the first receiving portion, comprising a driving portion, comprising a biasing element and a sleeve that supports the biasing element, a first locking portion at least partially extending into the first receiving portion, and a second locking portion, comprising an elongated rocker arm and rotatably connected to the first receiving portion through a second shaft, wherein the first locking portion moves on the second locking portion and, in a first state of the locking mechanism, the second locking portion rotates about an axis of the second shaft along a first direction to drive the sleeve to release a limitation on the first locking portion.
A power tool, comprising:
- a tool body having an output shaft and a chuck device coupled to the tool body and formed on or connected to an output shaft of the tool body, the chuck device comprising:
- a connecting mechanism formed with a first receiving portion to receive the working accessory and extending along a first axis;
- and
- a locking mechanism, connected to the connecting mechanism and used for retaining the working accessory in the first receiving portion, comprising a driving portion, comprising a biasing element and a sleeve that supports the biasing element, a first locking portion at least partially extending into the first receiving portion, and a second locking portion rotatably connected to the first receiving portion through a second shaft, wherein, in a first state of the locking mechanism, the second locking portion rotates about an axis of the second shaft along a first direction to drive the sleeve to bias against the biasing element and the second locking portion drives the sleeve to release a limitation on the first locking portion.
A power tool, comprising:
- a tool body having an output shaft and a chuck device coupled to the tool body and formed on or connected to an output shaft of the tool body, the chuck device comprising:
- a connecting mechanism formed with a first receiving portion used for receiving the working accessory and extending along a first axis;
- and
- a locking mechanism, connected to the connecting mechanism and used for retaining the working accessory in the first receiving portion, comprising a driving portion, comprising a biasing element and a sleeve that supports the biasing element, a first locking portion at least partially extending into the first receiving portion, and a second locking portion, comprising an elongated rocker arm and rotatably connected to the first receiving portion through a second shaft, wherein the first locking portion moves on the second locking portion and, in a first state of the locking mechanism, the second locking portion rotates about an axis of the second shaft along a first direction to drive the sleeve to release a limitation on the first locking portion.
