Abstract
A multi-link miter saw includes a base, a table supported on the base, a supporting unit connected to the table, a linkage unit connected to the supporting unit, a cantilever arm unit including a cantilever arm pivotally connected to the linkage unit and a connection member pivotally connected between the cantilever arm and the linkage unit for enabling the cantilever arm to be driven by the linkage unit and the connection member to move along a horizontal axis between the rear edge and front edge of the base, and a cutting unit pivotally connected to the cantilever arm unit. Based on the arrangement of the linkage unit and the cantilever arm unit, the cutting unit can be moved smoothly relative to the table, thus enhancing operation stability.
Claims4
A multi-link miter saw, comprising:
- a base comprising a front edge and an opposing rear edge;
- a table mounted at said base, said table comprising an axle holder disposed at said rear edge;
- a supporting unit disposed at said rear edge and connected to said axle holder of said table;
- a linkage unit connected to said supporting unit and swingeable between said rear edge and said front edge;
- a cantilever arm unit pivotally connected to said linkage unit, said cantilever arm unit comprising a cantilever arm pivotally connected to said linkage unit and a connection member pivotally connected between said cantilever arm and said linkage unit, said cantilever arm being drivable by said linkage unit and said connection member to move along a horizontal axis between said rear edge and said front edge;
- and
- a cutting unit comprising a saw blade holder pivotally connected to said cantilever arm unit, and a saw blade rotatably mounted in said saw blade holder,
- wherein said linkage unit comprises a first link connected to said supporting unit, a second link pivotally connected to said first link, a third link pivotally connected to said first link opposite to said second link, and a fourth link pivotally connected between said second link and said third link;
- said cantilever arm of said cantilever arm unit is pivotally connected to said fourth link of said linkage unit;
- said connection member is pivotally connected between said cantilever arm and said third link, and
- wherein said first link of said linkage unit comprises a first pivot-connection portion disposed adjacent to said axle holder, and a second pivot-connection portion disposed opposite to said first pivot-connection portion and pivotally connected to said second link;
- said third link comprises a lower pivot-connection portion pivotally connected to said first pivot-connection portion, an upper pivot-connection portion disposed opposite to said lower pivot-connection portion and pivotally connected to said fourth link, and a middle pivot-connection portion disposed between said lower pivot-connection portion and said upper pivot-connection portion and pivotally connected with said connection member.
