Abstract
A positioning device for a miter saw includes a working table, an elastic member, and a lever member. The elastic member has a movable portion adapted to be adjacent to a scale disc of the miter saw, and a protruding portion. The lever member is disposed in the working table, and has a linking portion connected to the movable portion, and a handle portion movable to convert the elastic member from a locking state for engaging the protruding portion with one of notches in a scale disc of the miter saw so that the working table is non-rotatable, to a releasing state for moving the movable portion away from the scale disc so that, the protruding portion is disengaged from the one of the notches to permit rotation of the working table.
Claims12
A positioning device adapted for use in a miter saw, the miter saw including a base seat and a scale disc that is disposed on the base seat, and that is formed with a plurality of notches, said positioning device comprising:
- a working table including a main portion that is adapted to be disposed above and connected rotatably to the base seat, and a mounting portion that extends in an extending direction from a side periphery of said main portion;
- an elastic member having
- a fixing portion that is connected fixedly to said working table,
- a movable portion that is opposite to said fixing portion and that is adapted to be adjacent to the scale disc, and
- a protruding portion that is connected to said movable portion, and that is adapted to removably engage one of the notches of the scale disc;
- and
- a lever member disposed in said mounting portion of said working table, and having
- a linking portion that is connected to said movable portion of said. elastic member, and
- a handle portion that is opposite to said linking portion, said handle portion of said lever member being movable to convert said elastic member from a locking state for engaging said protruding portion of said elastic member with the one of the notches so that said working table is non-rotatable relative to the base seat, to a releasing state for moving said movable portion of said elastic member away from the scale disc so that said protruding portion is disengaged from the one of the notches to permit rotation of said working table relative to the base seat.
