Abstract: A shockproof spindle includes a spindle inserted into an elastomer, a compressible structure, and a sleeve, a hollow cylinder, sequentially. The sleeve caps the elastomer while the elastomer presses on the top of the base fixed under the spindle. The ball keeps contact the chute of the spindle and the chute of the sleeve. In addition to all of the above, the elastomer held between the base and the sleeve absorbs the impact when a tool installed on the end of the spindle is shocked against the workpiece during operation process. Since the spindle works smoothly owing to the effect of the elastomer, the operators work more easily, and the damage or destruction of assembly precision, made by the impact, of the parts in the electric tool is avoided.

Abstract: A clutch device for a power tool includes a case in which a washer, a clutch, a clutch ring, planet gears and a sun gear are installed. The washer is connected with pins to which springs are respectively mounted. When switching and setting the torque by rotating the torque member, the pins do not extend through the clutch. The output torque of the tool is smaller than the input torque of the main shaft, the clutch ring is rotated by the sun gear and the planet gears. The ratchet teeth of the clutch ring are disengaged from the clutch teeth of the clutch. When switching to the drill mode, the pins extend through the clutch and contact with the clutch ring, the motor activates the gear box. Because the clutch ring is fixed by the pins and cannot rotate, the gear box outputs the maximum torque to drill objects.
