Abstract:
1. A workbench for a power tool comprising: a table on which the power tool is placed; a first support leg having an upper end rotatably mounted on one end side of the table and a lower end, the first support leg extending downward toward an other end side of the table from the upper end to the lower end; a second support leg having an upper end and a lower end, the upper end being mounted on the other end side of the table in such a manner as to be horizontally movable with respect to the table, the second support leg extending downward toward the one end side of the table from the upper end to the lower end and intersecting with the first support leg: a shaft that rotatably connects intersections of the first and second support legs: a handle held by a user of the workbench, the handle being disposed on the other end side of the table, wherein, when the user of the workbench raises or lowers the handle, the first and second support legs rotate on the shaft, so that the table is moved vertically between a lower position of a predetermined height and a upper position higher than the lower position, while horizontally moving with respect to the upper end of the second support leg, wherein the handle is slidably and pivotally connected to the table when the user of the workbench pulls the handle away from the table and raises or lowers the table; a lock mechanism comprising: a lock release member that releases the table locked by the lock mechanism, wherein the lock release member includes an elongated element disposed below the upper surface of the table and extending along the table toward the handle, and the lock mechanism is released when the user pulls the elongated element in the longitudinal direction of the elongated element away from and out of the at least one of the plurality of grooves, wherein, when the table is placed in the upper or intermediate position, the engaging member is rotated toward the movable element by the biasing force of the elastic member and is engaged with the upper position engagement recess or the intermediate position engagement recess, thereby locking the upper end of the second support leg and the table against relative movement with respect to each other, and when the engaging member is rotated away from the movable element by the pulling operation of the lock release member, the engaging member is disengaged from the upper position engagement recess or the intermediate position engagement recess, thereby releasing the lock mechanism.
