HAND-OPERATED PLANER PROVIDED WITH BOTH A FIXED WORKBENCH AND A LIFTING MECHANISM WITH A LOCKING FUNCTION

A hand-operated planer provided with both a fixed workbench and a lifting mechanism with a locking function is combined with a hand-operated planer， which includes a base， a movable workbench， a fixed workbench and a lifting mechanism. The lifting mechanism is composed of a connecting seat， a position-limiting member， an operating rod and a positioning block. When the handle of the operating rod is moved， the operating rod will actuate the position-limiting block of the position-limiting member to operate and drive the driven plate of the connecting seat to rotate via transmission of the connecting rod and thus， the movable workbench assembled above the axis of the connecting seat can be adjusted in height.

一种兼具固定工作台与带锁紧功能升降机构的手动刨床（hand-operated planer），其包含底座、活动工作台、固定工作台及升降机构。该升降机构由连接座、限位件、操作杆及定位块构成。当拨动操作杆的手柄时，操作杆将驱动限位件的限位块动作，并通过连杆传动带动连接座的从动盘转动，由此可对装配于连接座轴线上方的活动工作台实现高度调节。
