[0038]Specifically, such asfigure 1 withFigure 6 As shown, the searner device generally moves the hand-driven handle of the electric rails on the wall by mounting the base 13 to the robot gripping wall body, and the flexibility is insufficient, so the base 15 is provided. Startup When the cylinder 9 is protruded when the cylinder 9 on the inside of the pedestal 15 is protruded, the cylinder 9 output ends the piston rod 10 in the end of the cylinder 9 output on the other side of the base 15, and the moving block 7 is at the top of the base 15. Left and right, the guide rod 8 serves as a translation of the moving block 7, and the mating slot 17 enhances the movement stability, and the limit block 16 prevents the moving block 7 internally from moving slipping, restricting the moving stroke, and the handle device can also be Plamation is translated within the distance and the flexibility is higher.
