The receiving groove 413a is a dharma type in which a narrow portion is continuously formed in front of a wide portion opened to the rear end edge, and can receive the flange portion 22 in the vertical direction in the wide portion, and the narrow portion has a small diameter. Only the shaft portion 21 can be received.

  The lock cam 42 and the operation lever 43 are arranged so as to face each other with respect to the receiving groove 413, are pivotally supported on the frame body 41 by pivot shafts 44 and 45, respectively, and are rotatable in parallel with the bottom plate 411 in the insertion space S. It is.

  The lock cam 42 includes a main body portion 421 and a first and second pair of holding pieces 422 and 423 extending so as to face each other from both ends of the main body portion. It can freely rotate forward and backward by a predetermined angle between the positions (FIG. 8), and is normally urged to rotate to a non-lock position by a spring 46.

  The first holding piece 422 is pushed by the flange portion 22 of the leg 2 that moves forward in the receiving groove 413a of the upper plate, and the first contact surface 422a that rotates the lock cam 42 from the unlocked position to the locked position. It has an engagement surface 422b provided on the tip side on the extended surface of the contact surface, and a sliding surface 422c provided on the tip portion. The second holding piece 423 has a second abutting surface facing substantially parallel to the leg abutting portion 22 inserted into the receiving groove 413a so as to hold it between the first abutting surface 422a. 423a. The contact surface 423a is located behind the flange portion 22 in the locked position (FIG. 8) and is disposed so as to cross the receiving groove 413a. The main body portion 421 has an inner side surface 421a that faces the right side surface of the heel portion 22 of the leg at the locked position.

  The operation lever 43 includes a passive piece 431 extending from the pivot portion into the insertion space, an operation piece 432 extending from the pivot portion to the outside of the insertion space S, and a stopper piece 433 projecting toward the tip of the passive piece 431. The operation lever 43 allows the stopper piece 433 to pass through the opening 414a formed in the front plate 414 of the frame body, and is in the unlocked position (FIG. 6) and the locked position (FIG. 8) in the range of the opening 414a around the pivot 45. ), And is normally urged to rotate to a non-lock position by a spring 47.

  The passive piece 431 has a sliding contact surface 431a and a locking surface 431b. A sliding surface 422c of a lock cam that rotates from the unlocked position to the locked position is brought into sliding contact with the sliding contact surface 431a, thereby pushing the operation lever 43 from the unlocked position to the locked position. The sliding contact surface 431a is disposed so as to face the inner side surface 421a of the lock cam on the left and right sides with the flange portion 22 of the leg interposed therebetween at the lock position shown in FIG. The locking surface 431b is disposed so as to engage with the engagement surface 422b on the first holding piece 422 in the locked position to prevent the lock cam 42 from returning to the unlocked position.

  As shown in FIG. 3, the operation piece 432 extends from the rear end edge of the upper plate 413 to the outside of the outer edge A1 of the fixation target device A at the fixed position, and is configured to be rotatable from the outside.

  The bottom plate 411 extends to the outside of the outer edge A1 of the fixation target device A at the fixed position, and a predetermined relative position with the operation piece 432 at the lock position so that it can be visually confirmed that the operation lever 43 is at the lock position. A lock confirmation display 411b is displayed.

  When fixing the device A to be fixed on the support member B, the rear leg 2 is arranged in the wide part of the receiving groove 413a of the receiving metal 4, and the front leg 2 is larger than the receiving groove 313a of the receiving metal 3. If it is dropped into this corresponding to the diameter hole portion (the disengagement position in FIG. 2) and pushed forward, it is automatically locked at a predetermined fixed position.

  That is, when the device A is pushed forward (upward in the figure) from the disengagement position in FIGS. 3 and 6, the leg 2 comes into contact with the first contact surface 422a of the lock cam 42 as shown in FIG. 44, the sliding surface 422c is slidably contacted with the sliding contact surface 431a of the operation lever 43, and is rotated counterclockwise about the pivot 45. When the device A reaches the fixed position, the sliding surface 422c of the lock cam 42 is disengaged from the sliding contact surface 431a of the operating lever 43, and at the same time, the operating lever 43 is rotated clockwise by the spring 47 to the locked position shown in FIG. It reaches. In this state, the engagement surface 422b of the lock cam 42 is engaged with the engagement surface 431b of the operation lever 43, and the lock cam 42 is restrained at the lock position. The leg 2 of the device A to be fixed reaches the fixed position, and the front and rear side surfaces thereof face the first and second contact surfaces 422a and 423a. Therefore, the leg 2 cannot be retracted to the separation position and is restrained at this position. . During this time, the front leg 2 is elastically pushed rearward by the front holding spring 32, while the rear leg 2 contacts the contact surface 422a of the lock cam 42, and the front and rear legs 2 are moved upward by the leaf springs 311a and 411a. Since the upper surface of the flange 22 is pressed against the lower surfaces of the upper plates 313 and 413, the device A to be fixed is elastically held back and forth and up and down. Whether or not the device A is securely locked at the fixed position can be easily confirmed from the positional relationship between the distal end portion of the operation lever 43 and the confirmation display 411b of the catch 4. The device A is not carelessly detached from the support member B due to vibration or impact.

  When the device A to be fixed is removed from the support member B, the operation lever 43 extending outward from the outer edge A1 of the device A is moved to the non-lock position side against the spring force (counterclockwise in FIG. 8). Rotate to The engagement surface 422b of the lock cam 42 is disengaged from the engagement surface 431b of the operation lever 43, and the lock cam 42 is rotated to the non-lock position side (counterclockwise) by the force of the spring 46, and at the same time, the leg 2 is moved along the receiving groove 413a. Push out to the rear side. In this state, the device A can be detached from the support member B.
