Solution

The kink or bend in a thermometer helps the mercury to stay at the same level for a few time an does let it to come down fast. So, in clinical thermometer the doctor has to observe the temperature after taking it from the patient, so it should not come down fast and hence it has kink. But in laboratory, the temperature changes continuously and so there doesn't require any kink to retain readings.
