Abstract: A pin puller comprising a pull rod, a limiting member, and a supporting sleeve. The pull rod comprising a threaded portion, and the limiting member is screwed on the threaded portion. The supporting sleeve defining a receiving through hole, and the threaded portion movably passing through the receiving hole thereby the supporting sleeve can be movably sleeved on the threaded portion and limited by the limiting member. One end of the threaded portion can be received in the receiving hole defining a stepped hole. The pin puller further comprising a locking member, the locking member can be detachably latched into the stepped hole, and partially protruding from the threaded portion.

Abstract: A clamping mechanism includes a mounting member, three sealing assemblies, three clamping assemblies, and six adjusting valves. The mounting member defines a receiving hole axially and three mounting holes radially, the three mounting holes communicate with the receiving hole. Each sealing assembly includes a top seal and a bottom seal sealing opposite ends of corresponding mounting hole. Each clamping assembly includes a holding member and a piston, a first end of the holding member extends through the axial hole and is received in the receiving hole, the piston is fixed to the holding member and divides the mounting hole into a first chamber and a second chamber. The six adjusting valves respectively communicate with the first chambers and the second chambers of the three mounting holes.

Abstract: A manipulator includes a controlling seat, a robot arm assembly and a polishing mechanism. The robot arm assembly is rotatably connected to the controlling seat; and the polishing mechanism is mounted on the robot arm assembly. The polishing mechanism includes a housing with a first mounting portion and a second mounting portion, a pair of magnetic valves mounted in the housing and electrically connected to the controlling seat, a first polishing assembly partially received in the first mounting portion, and a second polishing assembly partially received in the second mounting portion. The first polishing assembly and the second polishing assembly define an angle therebetween and are respectively connected to the pair of magnetic valves, such that the pair of magnetic valves controls the first and the second polishing assembly respectively to polish one or more workpiece. The present invention further discloses a polishing mechanism of the manipulator.
