SMA wire driving clamp holder with resistor capable of sensing force and displacement automatically

The invention discloses an SMA wire driving clamp holder with a resistor capable of sensing force and displacement automatically. The SMA wire driving clamp holder is mainly composed of a rack guide rail component, a power-on end component, a spring, an SMA wire, locking rings, a fixed end component, a movable end component and a measuring end component. According to the SMA wire driving clamp holder, all the components and the locking rings are installed on a guide rail, except the moving end component, all the components are locked through the locking rings, the two ends of the SMA wire are clamped through the copper sheets, the middle portion of the SMA wire is installed in a pulley groove, and the spring is installed between the moving end component and the measuring end component; and when the SMA wire driving clamp holder is powered on, the SMA wire driving clamp holder clamps an object, after the SMA wire driving clamp holder is powered off, the SMA wire restores to the original length and releases the
