Abstract
A router includes a housing and a motor assembly disposed within the housing. The motor assembly includes a driven shaft having a cavity on a first end of the driven shaft. The router includes a collet that is configured to mate into the cavity of the driven shaft with the collet being configured to grip a shank of a router bit. The router includes a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.
Claims16
A router, comprising:
- a housing;
- a motor assembly disposed within the housing, the motor assembly comprising a driven shaft having a cavity on a first end of the driven shaft;
- a collet that is configured to mate into the cavity of the driven shaft, the collet being configured to grip a shank of a router bit;
- and
- a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.
A router, comprising:
- a housing;
- a motor assembly disposed within the housing, the motor assembly comprising a driven shaft having a cavity on a first end of the driven shaft, wherein a portion of the first end of the driven shaft comprises external threads;
- a collet that is configured to mate into the cavity of the driven shaft, the collet being configured to grip a shank of a router bit;
- a nut having an axial bore with internal threads for cooperating with the external threads on the first end of the driven shaft;
- and
- a locking mechanism that is configured to engage the nut to prevent rotation of the nut such that a rotation of a second end of the driven shaft when the locking mechanism is engaged causes at least one of tightening and loosening of the collet.
