Grinder with easily installable/detachable grinding disc and a linkage effect
First Claim
1. A grinder with easily installable/detachable grinding disc and a linkage effect, comprising:
- a main body in which a rotary shaft is disposed for a grinding disc being mounted under a bottom end of the rotary shaft and drivable by the rotary shaft;
a controlling button mounted on the main body and switchable between an activation position and a shutoff position for powering on or off the grinder;
a linking member connected with the rotary shaft and synchronously rotatable therewith; and
a chucking mechanism mounted in the main body and movable between an engaging position and a releasing position, whereby when the chucking mechanism is moved to the engaging position, the chucking mechanism chucks the linking member, while when the chucking mechanism is moved to the releasing position, the chucking mechanism releases the linking member from the chucked state;
the controlling button having a linkage function with the chucking mechanism, whereby when the controlling button is positioned in the activation position, the chucking mechanism is positioned in the releasing position and cannot be moved to the engaging position, while when the controlling button is positioned in the shutoff position, the chucking mechanism can be moved from the releasing position to the engaging position where the controlling button cannot be switched to the activation position.

Abstract
A grinder with easily installable/detachable grinding disc and a linkage effect. The grinder includes a main body in which a rotary shaft is disposed for a grinding disc mounted under a bottom end of the rotary shaft. A controlling button is switchable for powering on or off the grinder. A linking member is connected with the rotary shaft. A chucking mechanism is mounted in the main body for chucking the linking member. The chucking mechanism has a linking relationship with the controlling button. After powered off, the chucking mechanism is operable to chuck the linking member and prevent the rotary shaft from rotating. At this time, a user can conveniently replace the grinding disc. During replacement of the grinding disc, it is impossible to switch on the controlling button. When the chucking mechanism releases the linking member. The controlling button can be switched on. At this time, it is impossible for the chucking mechanism to chuck the linking member.

13. A grinder with easily installable/detachable grinding disc and a linkage effect, comprising:
-
a main body in which a rotary shaft is disposed for a grinding disc being mounted under a bottom end of the rotary shaft;
a slide way being formed inside the main body;a controlling button mounted on the main body and switchable between an activation position and a shutoff position for powering on or off the grinder; a linking member connected with the rotary shaft and synchronously rotatable therewith; and a chucking mechanism mounted in the slide way of the main body and movable along the slide way between an engaging position and a releasing position, whereby when the chucking mechanism is moved to the engaging position, the chucking mechanism chucks the linking member, while when the chucking mechanism is moved to the releasing position, the chucking mechanism releases the linking member from the chucked state, the controlling button having a linkage function with the chucking mechanism, whereby when the controlling button is positioned in the activation position, the chucking mechanism is positioned in the releasing position and cannot be moved to the engaging position;
while when the controlling button is positioned in the shutoff position, the chucking mechanism is movable between the releasing position and the engaging position where the controlling button cannot be switched to the activation position. - View Dependent Claims (14, 15, 16, 17)
