The fourth locking member 13 is a screw adapted to the screw hole, and the screw passes through a hinged end of the fourth hinge member 15 and is screwed with the screw hole, which can also at least partially achieve the above-mentioned effects.

It should be noted that when the first supporting rod 201 is in the unfolded state, the end surface of the first supporting rod 201 abuts against the first connecting rod 101 to limit the position of the first supporting rod 201. However, due to the existence of assembly errors, the end surface of the first supporting rod 201 is not attached to the first connecting rod 101, that is, the first supporting rod 201 is inclined relative to the first connecting rod 101, which is not favorable for installing the first calibration element.
