Claims18
An apparatus, comprising:
- a captive screw, comprising:
- an upper portion, an upper middle portion, a central middle portion, a lower middle portion, and a lower portion;
- the central middle portion comprising a threaded portion;
- the lower portion comprising a barbed portion;
- the upper middle portion and the lower middle portion comprising a smooth portion;
- and
- the upper portion comprising a grip portion,
- wherein the captive screw is configured with a first attachment portion and a second attachment portion to attach to a first member of an auxiliary device, and
- wherein the captive screw is configured to act as a set screw with respect to a second member of an auxiliary device,
- wherein the second attachment portion is flexible.
An apparatus, comprising:
- a captive screw, comprising:
- an upper portion, a middle portion, and a lower portion;
- the middle portion comprising a first attachment portion configured for removably attaching the captive screw to a first member of an auxiliary device;
- the lower portion comprising a second attachment portion configured for permanently attaching to the first member of the auxiliary device;
- and
- the upper portion comprising a grip portion,
- wherein the second attachment portion is devoid of threads,
- wherein a cross-sectional diameter of the second attachment portion is greater than a minor diameter of the first attachment portion,
- wherein the second attachment portion is flexible.
A method, comprising:
- inserting a captive screw into a first member of an auxiliary device, the captive screw comprising:
- an upper portion, an upper middle portion, a central middle portion, a lower middle portion, and a lower portion;
- the central middle portion comprising a threaded portion;
- the lower portion comprising a barbed portion;
- the upper middle portion and the lower middle portion comprising a smooth portion;
- and
- the upper portion comprising a grip portion;
- tightening the captive screw such that it is configured to act as a set screw with respect to a second member of the auxiliary device;
- and
- adjusting a longitudinal position, a rotational position, or both of the first member with respect to the second member of the auxiliary device.
A apparatus, comprising:
- a captive screw, comprising:
- an upper portion, an upper middle portion, a central middle portion, a lower middle portion, and a lower portion;
- the central middle portion comprising a threaded portion;
- the lower portion comprising a barbed portion;
- the upper middle portion and the lower middle portion comprising a smooth portion;
- and
- the upper portion comprising a grip portion;
- and
- an auxiliary device comprising a first member and a second member, wherein the captive screw is positioned in a channel of the first member, wherein the first member and the second member are configured to be locked down when the captive screw is engaged and wherein the first member and the second member are configured to be longitudinally and rotationally movable with respect to each other when the captive screw is disengaged.
