Blood pressure testing device

A blood pressure testing device for a finger, comprising:

• a housing;
• at least one cover plate connected pivotably to the housing;
• at least one detecting element, each of which is configured to detect an electrocardiogram signal and a pulse signal, and arranged to be accommodated within and connected with the housing and provided opposite to corresponding one of the at least one cover plate so as to cooperate to define collectively a testing hole therebetween;
• and
• at least one adjusting component, each of which is arranged to be connected with the corresponding one of the at least one cover plate, and configured to drive the corresponding one of the at least one cover plate to carry out one of the operations comprising:
• lifting up to move away from a corresponding one of the at least one detecting element, and falling down to approach the corresponding one of the at least one detecting element,
• wherein the number of the at least one detecting element is at least three, and the number of the testing holes is also at least three, and
• wherein each of the at least one adjusting component further comprises:
• an intermittent transmission mechanism comprising a driving member connected with the power input element and a driven member, both the driving member and the driven member cooperating with each other by intermittently forming a separable engagement therebetween to drive the driven member in an intermittent motion, and the driven member being connected with the corresponding one of the at least one cover plate to drive the corresponding one of the at least one cover plate in an intermittent motion synchronously.
