Therefore, the protruding length of the neck portion 43 of the protruding portion 40 can be made equal to the thickness of the sliding portion of the guiding portion 12, and the protruding portion 40 can be prevented from swimming with respect to the guiding portion 12. As a result, even if a large load is applied to the fixing device 1, and the protruding portion 43 is inclined with respect to the guiding portion 12, the opening end edge of the guiding portion 12 can be further prevented from being deformed in a direction away from the direction.

Further, the locking portion 21 includes a locking claw 22 that is provided at the locking portion 21 to position the cookware mechanism 30 or the setting mechanism 10 at a predetermined position, and a button is integrally formed above the locking claw 22 Since the button 23 and the locking claw 22 are urged in the locking direction by the elastic member 24, the locking claw 22 can be locked to the engaged portion 45a, 45b by the pressing force of the elastic member 24. , the state of 45c.

Further, when the cooker mechanism 30 and the setting mechanism 10 are coupled, the protruding portion 40 can be easily slid toward the guiding portion 12, and the locked portions 45a, 45b, and 45c can be easily multiplied by the inclined surface 27 of the locking claw 22. The locking claws 22 are locked to the engaged portions 45a, 45b, and 45c.

Further, the arm portion 33 of the cooker main body portion 32 that overlaps the joint main body portion 42 and the bolt 36 provided on the projecting portion 34 of the cooker main body portion 32 are inserted into the rod 3, and only the bolt 36 is tightened. It is possible to use the rod 3 to cook. As a result, the cooker mechanism 30 of the fixing device 1 can be easily fixed to the rod 3.

Further, in a state in which the rod mechanism 3 is selectively held by the cooker mechanism 30 in the plural direction, the locked portions 45a, 45b, and 45c can be locked to the locking portion 21.

When the cooker mechanism 30 is coupled to the setting mechanism 10, since the neck portion 43 of the square column is fitted to the guide portion 12, the cooker mechanism 30 is difficult to rotate. Therefore, the card can be moved only by directly moving the cooker mechanism 30. The stopper 21 is locked to the engaged portions 45a, 45b, and 45c. Further, since at least three of the locked portions 45a, 45b, and 45c are formed, the cooker mechanism 30 can be locked to the setting mechanism 10 by at least three directions.

The movement along the surface 15 of the guide portion 12 along the sliding surface 47 and the table 11 is eliminated by the portion along the guide portion 12 of the table 11 being fitted between the sliding surface 47 and the head portion 44 in the vicinity of the neck portion 43. Even if a large load is applied to the fixing device 1 and the protruding portion 40 is inclined with respect to the guiding portion 12, the opening end edge of the guiding portion 12 can be further prevented from being deformed in a direction away from the direction.

Since the engaged portions 45, 45a, 45b, and 45c are fitted between the surface of the button 23 on the side of the locking claw 22 and the locking claw 22, the engaged portions 45, 45a, 45b, and 45c are unnecessary at the button. 23 and the locking claw 22 move between.
