PCT No. PCT/SE89/00593 Sec. 371 Date Apr. 15, 1991 Sec. 102(e) Date Apr. 15, 1991 PCT Filed Oct. 25, 1989 PCT Pub. No. WO90/04361 PCT Pub. Date May 3, 1990.An assembly which includes supporting structure for a gripping device such as a pair of tweezers. The support structure includes a cylindrical member for rotational support of the tweezer legs relative to a cross-piece which carries a support leg. The support leg extends substantially in parallel with the tweezer legs, and is provided with a support foot for contact with the work piece. At its rear end, the support leg is adjustably connected to the cross-piece. A retention device maintained the tweezer legs at a specific location along the axial axis during operation. A maneuver sleeve surrounds and is displaceably guided along the tweezer gripping legs for accomplishing compression and opening, respectively, of the tweezer legs upon longitudinal movement. Preferably, a maneuver rod extends along the central axis through a hollow cylindrical portion defining the base or stem of the tweezer legs. The maneuver rod is connected to the maneuver sleeve by, for example, a pin extending between the tweezer legs. By forcing the maneuver rod downwardly, the attached maneuver sleeve slides over the legs so as to compress inwardly the outwardly diverging legs. The retention device acts to maintain the tips of the tweezer legs to a position between the maneuver sleeve and the support foot so as to help avoid piercing of a person or animal's skin. |
