Abstract: A clamping device for a power tool that axially secures a disc shaped tool to its spindle. The clamping device securely attaches a grinding wheel or circular saw to a power tool by a contact surface on the clamping device and a screw-on flange that directly contacts the tool. The clamping device counteracts inertial forces that loosen the tool upon sudden deceleration.

Abstract: The present invention relates to a power tool with a clamping device for axially securing a disk shaped tool, more particularly, relates to a power tool with a clamping device for securing a grinding wheel, which will cut the workpiece when the cutting work is doing, to a rotatable spindle. Said motor powered tool including a spindle 3, a tool 5, a clamping device 8 and a flange 2. Said clamping device 8 includes a first clamping part 13, a second clamping part 1, and an elastic element 7 which is disposed between said first clamping part 13 and said second clamping part 1, a clamping contact surface 17 is provided on said first clamping part 13, and a second clamping contact surface 18 is provided on said flange 2, said tool 5 is disposed between said first clamping contact surface 17 and said second clamping contact surface 18.

Abstract: A power tool with at least one handle, comprises at least one handle [1], a power tool body [12], said handle [1] includes at least a gripping member [2], at least one elastic vibration absorbing members are disposed with said gripping member [2]. Said elastic members [3,4] are attached in an inside bore [13] of said gripping member [2], a rigid connecting member [5] go through said elastic members [3,4] and connected with them. Said rigid connecting member [5] also connect to attachment member [7], said attachment member [7] connect to elastic members [4,6]. Said rigid connecting member can increase the strength of said elastic anti-vibration members and also can protect them from wearing off, said rigid connecting member and said attachment member all connected by said elastic anti-vibration members to said gripping member, so the vibration-absorbing effect is perfect.
