When the pressing plate 202g is squeezed, the spring 202h can be applied with a squeezing force, and the limit block 202e moves to release the limit of the rotating plate 202d, and the rotating plate 202d is rotated. The rotating plate 202d drives the threaded rod 202b to rotate, and the rotation of the threaded rod 202b can drive the moving column 202a to move, and the movement of the moving column 202a can drive the movable block 201d to move, and the movement of the movable block 201d drives the moving bar 201c to move, and the moving bar 201 c can drive the moving block 201b to move, and the movement of the moving block 201b can drive the clamping plate 201a to move. The setting of the clamping plate 201a can release the limit of the duplexer 103, so that the duplexer 103 can be removed. After the duplexer 103 is repaired, the duplexer 103 is placed on the placement plate, and then the turntable 202d is rotated to fix it. After the duplexer 103 is fixed, in order to prevent the turntable 202d from being accidentally touched and causing the clamping of the duplexer 103 to loosen, the pressing plate 202g is released. At this time, the rebound force of the spring 202h can drive the limit block 202e to return to its original position, so as to limit the turntable 202d again, and finally the closed door 203a is closed. After the closed door 203a is closed, in order to prevent the closed door 203a from being accidentally touched and opened, the closed door 203a can be limited by engaging the locking rod 203c with the lock hole.
