An electric device includes a main body, a supporting crutch and a pivot mechanism connecting the body to the crutch. The body is rotated around the crutch through the pivot mechanism. The pivot mechanism includes first and second bearing shims. The first bearing shim has a limiting salient, which has a first sidewall, a second sidewall and an inclined surface. The inclined surface is tilted from the second sidewall to the first sidewall. The second bearing shim has a sliding salient. When the sliding salient is disposed on the first/second sidewall, the main body is positioned at a first/second position. The sliding salient crosses the first sidewall and slides on the inclined surface to the second sidewall by a first force. The sliding salient crosses the second sidewall and slides on the inclined surface to the first sidewall by a second force larger than the first force.

Abstract:
An electromagnetic coaxial driving injection apparatus, having a linear motor for driving injection and a rotation motor for metering. The linear motor and the rotation motor of both the injection and metering motors and an injection screw are set on a common axis. A connecting device connects moving parts of the motors with the injection screw. Stationary parts of the motors are fastened on a frame and forward-backward moving unit, not moving during injection and metering. Due to the arrangement of the moving parts and the injection screw on a single axis, moving parts are lessened, and transmission losses are minimized. Since the number of structural parts is low, only the moving parts of the motors move during injection while the stationary parts thereof remain at rest, thus greatly reducing inertia. Furthermore, since the moving axis of the injection screw and the injection screw are linked, without being connected with stators or other structural parts, injection is performed with minimal friction, enhancing effectiveness of the apparatus.The main characteristic of the present invention is that, due to direct driving of injection without mechanical transmission, the effects of hysteresis and backlash are avoided. Furthermore, inertia and friction are reduced. The present invention increases the response and reappearance of the system.
