Abstract
A manual device includes a control lever pivoted to a hand grip for activating an activation rod so as to actuate an adjustment piece to cause two holding ends of two grasping arms to move toward each other to take hold of an object. The adjustment piece has a toothed bar. The grasping arms are provided with a toothed action end which is engaged with the toothed bar of the adjustment piece. As the adjustment piece is manually turned, the grasping arms are caused to move toward or away from each other such that the distance between the two holding ends of the two grasping arms is adjusted in accordance with the size of the object.
Claims3
A manually-operated device for picking up an object, said device comprising:
- a hand grip provided in an interior with a pivoting portion;
- a control lever pivoted at one end with said pivoting portion such that another end of said control lever juts out of said hand grip;
- a shank fastened at one end to said hand grip and provided with a hollow interior;
- an activation rod fastened at one end to said control lever such that said activation rod is received in the hollow interior of said shank;
- a retaining piece fastened at one end to another end of said shank and provided at another end thereof with a pivoting portion;
- an adjustment piece comprising a toothed bar, said toothed bar comprising one end which is fastened to another end of said activation rod in conjunction with a spring;
- and
- two grasping arms comprising, at one end, a toothed action end, and at another end, a holding end, said two grasping arms being pivoted at the one end thereof with said pivoting portion of said retaining piece such that said toothed action ends of said two grasping arms are engaged with said toothed bar of said adjustment piece, thereby enabling said two grasping arms to move toward or away from each other by turning said adjustment piece whereby said adjustment piece is actuated to move linearly by said activation rod at such time when said control lever is triggered, thereby causing said two holding ends of said two grasping arms to move toward each other to take hold of an object.
