Abstract
A tool has a first member cooperatively associated with a second member. The first member has a first gripper integral at an end thereof The first member has an internal longitudinal groove in communication with a plurality of internal spaced locking grooves. The second member has a second gripper attached at a first end. The second member has a projection at a second end. The projection of the second member is received by the longitudinal groove. The second member is moveable with respect to the first member between a fully contracted position and a plurality of extended positions. In one of the plurality of extended positions, the protrusion is selectively received in one of the plurality of locking grooves to lock the members in one of the plurality of extended positions.
Claims20
A tool comprising:
- a first elongated cylindrical member having opposed first and second ends, the first member comprising a cylindrical wall defining an internal chamber extending from an opening in the second end inwardly at least a portion of a distance from the second end to the first end, the first member having a first gripper attached to the first end;
- and
- a second elongated member having opposed first and second ends, the second member having a second gripper attached to the first end,
- wherein the second end of the second member is configured to be inserted into the internal chamber of the first member through the opening, such that the second member is moveable axially with respect to the first member within the chamber, and wherein the first and second members have complementary locking structures such that second member is lockable in a plurality of locking positions within the internal chamber, wherein the first gripper and the second gripper are spaced different distances from each other in the plurality of locking positions.

A tool comprising:
- a first member comprising a first elongated cylindrical body, a first gripper attached to an end of the first cylindrical body, and an elongated internal chamber extending through the first cylindrical body, wherein the first gripper is integrally formed with the first cylindrical body;
- and
- a second member comprising a second elongated body having a first end having a receiver and a second end opposite the first end, and a second gripper attached to the first end of the second body, the second gripper having an extension received in the receiver to connect the second gripper to the second body, such that the second gripper is rotatable with respect to the second body,
- wherein the second end of the second member is configured to be inserted into the internal chamber of the first member, such that the second member is moveable axially with respect to the first member within the internal chamber, and wherein the first and second members have complementary locking structures such that second member is releasably lockable in at least one locking position within the internal chamber.
1 more element
A tool comprising:
- a first elongated cylindrical member having a first gripper attached to an end thereof, the first member having an internal chamber extending therethrough and a first connecting structure on an internal surface of the chamber;
- a second elongated member having a second gripper attached to a first end thereof, a second end configured to be inserted into the internal chamber of the first member, and a second connecting structure on an outer surface of the second member;
- wherein when the second end of the second member is inserted into the internal chamber of the first member, the projection of the second member is received by the longitudinal groove such that the second member is moveable axially with respect to the first member,
- wherein one of the first and second connecting structures comprises a longitudinal groove with a locking groove in communication with the longitudinal groove and extending transverse to the longitudinal groove,
- wherein another of the first and second connecting structures comprises a projection configured to slide within the longitudinal groove when the second end of the second member is inserted into the internal chamber of the first member, and
- wherein the second member is lockable in at least one extended locking position relative to the first member, including at least a first position, wherein the projection is received in the locking groove, wherein the first gripper is spaced a first distance from the second gripper in the first position, and the second member is further moveable to a fully contracted position, wherein the first gripper is spaced a second distance from the second gripper in the fully contracted position, the second distance being less than the first distance.
