In particular, the second side 6401d of the housing 6401 defines an engagement groove 6401c, and a side of the door 6401b close to the housing 6401 is arranged with an engagement portion 6401f, where the engagement portion 6401f can be moved into or out of the engagement groove 6401e: when the engagement portion 6401f is moved into the engagement groove 6401c, the clamping member 6402a abuts against the engagement portion 6401f to restrict the position of the door 6401b.

An end of the clamping member 6402a is arranged with a protrusion 6402d, and the engagement portion 6401f defines a groove 6401g. When the engagement portion 6401f is moved into the engagement groove 6401c, the protrusion 6402d is inserted into the groove 6401g to restrict the position of the door 6401b.

When the engagement portion 6401f moves into the engagement groove 6401c, the engagement portion 6401f squeezes or stretches the second clastic member 6402c, causing the second clastic member 6402c to deform and generate an clastic force. When the drive member 6402b drives the clamping member 6402a to release the restriction on the door 6401b, the clastic force acts on the door 6401b to cause the door 6401b to rotate relative to the housing 6401, so as to open the window 6401a.

The sample parameter analysis apparatus provided in the embodiments of the present disclosure is arranged with a connecting assembly to fix the door when the door covers the window, and the connecting assembly is capable of releasing the restriction on the door such that the door can move to open the window: In particular, a clamping member is arranged to restrict and fix the door when the door is closed, and a drive member is arranged to drive the clamping member to move so as to release the restriction on the door. Further, a first clastic member is arranged to connect the clamping member and the housing, such that when the clamping member releases the restriction on the door, the first elastic member deforms to generate an elastic force. The clastic force can cause the clamping member to return to its original position without the need to drive the clamping member to return to its original position again through the drive member, which is beneficial to simplifying the overall structure of the device.
