Abstract
A coupling device couples a first member and a second member. The coupling device includes: two protruding portions provided on the first member; a through hole formed to pass through the second member; two reception holes provided in the second member and each formed to connect to the through hole; and a fixing member having a first pressing portion and a second pressing portion. The fixing member is configured to, when being disposed in the through hole, change a distance between the first pressing portion and the second pressing portion due to application of a force to one end portion of the fixing member. The first pressing portion and the second pressing portion are formed to exert a fixing force on either corresponding one of the two protruding portions received in the two reception holes.

A coupling device for coupling a first member having a first axis and a second member having a second axis, comprising:
- two protruding portions provided on the first member, the two protruding portions being across from one another on opposite sides of a longitudinal first plane containing the first axis;
- a through hole formed to pass through the second member, the through hole having a through hole axis;
- the second member having a longitudinal second plane perpendicular to the through hole axis and containing the second axis;
- two reception holes provided in the second member, the two reception holes being across from one another on opposite sides of the longitudinal second plane, each reception hole formed to connect to the through hole and to receive one of the protruding portions;
- and
- a fixing member including a first pressing portion and a second pressing portion, wherein the fixing member is configured to, when being disposed in the through hole, be able to move the first pressing portion and the second pressing portion and change a distance between the first pressing portion and the second pressing portion due to application of a force to one end portion of the fixing member, and wherein
- the first pressing portion is formed to be able to contact and exert a fixing force on one of the two protruding portions received in one of the two reception holes and
- the second pressing portion is formed to be able to contact and exert a fixing force on the other of the two protruding portions received in the other of the two reception holes.
A coupling device for coupling a first member and a second member, comprising:
- two protruding portions provided on the first member;
- a through hole formed to pass through the second member;
- two reception holes provided in the second member, each reception hole connecting to the through hole and formed to receive one of the protruding portions;
- a first fixing element having a first pressing portion formed thereon, the first fixing element and the first pressing portion having monolithic one-piece construction;
- and
- a second fixing element having a second pressing portion formed thereon, the second fixing element configured to be threadedly engaged with the first fixing element, wherein:
- when the first fixing element and the second fixing element are disposed in the through hole with the second fixing element threadedly engaged to the first fixing element, and the first fixing element is rotated:
- the second fixing element translates within the through hole while being prevented from rotating therein, thereby changing a distance between the first pressing portion and the second pressing portion,
- the first pressing portion contacts and exerts a fixing force on one of the two protruding portions;
- and
- the second pressing portion contacts and exerts a fixing force on the other of the two protruding portions.
