Downhole Movable Joint Tool

An apparatus comprising:

• a plurality of downhole tools each comprising:
• a first sub;
• a second sub;
• and
• a movable joint movably connecting the first sub and the second sub to facilitate relative angular movement between the first sub and the second sub,
• wherein each of the downhole tools is operable to:
• connect together a first portion of the tool string and a second portion of the tool string and facilitate relative angular movement between the first portion of the tool string and the second portion of the tool string;
• and
• connect with another of the downhole tools to form a combined downhole tool operable to connect together the first portion of the tool string and the second portion of the tool string and facilitate relative angular movement between the first portion of the tool string and the second portion of the tool string.

An apparatus comprising:

• a downhole tool operable to connect within a tool string, wherein the downhole tool comprises:
• a first sub;
• a second sub;
• and
• a movable joint comprising:
• a socket member;
• a ball member disposed within the socket member, wherein the ball member comprises a plurality of channels each extending along an outer surface of the ball member;
• and
• a plurality of protrusions each connected to the socket member and disposed within a corresponding instance of the channels,
• wherein the movable joint:
• connects the first sub and the second sub;
• facilitates relative angular movement of the first sub and the second sub between a first position in which a first central axis of the first sub and a second central axis of the second sub are axially aligned and a second position in which the first central axis and the second central axis are positioned at a relative angle;
• and
• prevents relative rotation between the first sub along the first axis and the second sub along the second axis.
