Abstract (en)
[origin: EP0370952A1] The hand tool has a housing (1) and a handle (3) which is displaceably mounted relative to the housing (1). Compression springs (10) arranged so as to slope at an angle (B) relative to the direction of the main oscillation axis (A) are loaded relative to the housing (1) when the handle (3) is displaced. The increase in the spring force which takes place when the compression springs (10) are loaded, is compensated for in the direction of the main oscillation axis (A) by the angle (B) increasing and thus by the force component which acts in the direction (A) becoming smaller, which leads to the force which acts in the direction of the main oscillation axis (A) remaining constant. <IMAGE>
