Abstract
A grinder having a rotary shaft and a grinding disc mounted at a bottom end of the rotary shaft for grinding a work piece. A press button unit is disposed on a housing of the grinder. By means of pressing the press button unit, the rotary shaft of the grinder can be seized for replacement of the grinding disc. Before pressing the press button unit, a user must first angularly displace the press button unit. That is, the press button unit cannot be directly pressed without being first turned by a certain angle. Therefore, in operation, mis-touch of the press button unit can be avoided so as to avoid damage of the grinder.
