an elongated frame having a longitudinal axis and comprising opposite longitudinal members joined by intermediate and terminal cross members;

a screwdriver extending along the axis of said frame through and rotatable in said cross members and having a handle extending beyond said frame at one end thereof;

means including a compression spring continuously impelling said screwdriver toward an extreme position at the opposite end of said frame;

gripping means mounted on said frame at said opposite end thereof for closing toward said axis to hold an object such as a sink clip;

resilient means urging said gripping means into closed position; and

means extending along said frame and operable from said one end thereof to open said gripping means.

2. Apparatus according to claim 1, in which terminal members are hollow cylinders.

3. Apparatus according to claim 1, in which said gripping means comprises a pair of jawed arms centrally pivoted at the ends of said longitudinal members, a tension spring urging said jaws into gripping position, a pair of links pivoted to each other and to the ends of said arms remote from the jaws, a pull rod connected to the common pivot of said links and extending toward said one end of said frame for linear displacement to open said jaws against the action of said tension spring, and spring means normally urging said pull rod toward said other end of said frame.
