Multifunctional mechanical gripper

The utility model relates to a multifunctional mechanical gripper which comprises a mounting frame, a first clamping arm, a second clamping arm, a driving device and a limiting device. The first end of the first clamping arm is slidably connected with the mounting frame, the first end of the second clamping arm is detachably connected with the mounting frame, the first clamping arm and the second clamping arm each comprise a plurality of sections of supporting arms which are sequentially connected, and the central axes of the multiple sections of supporting arms are collinear. The cross sectional areas of the multiple sections of supporting arms of the first clamping arm and the second clamping arm are sequentially reduced from the first end to the second end. The driving device and the limiting device are both arranged on the mounting frame, the driving device is connected with the first clamping arm to drive the first clamping arm to slide, and the limiting device can abut against the first clamping arm.
