The second link 5 is rotatably mounted on the column 1 about a third rotation axis L3, the third rotation axis L3 is located below a line n connecting a rotation center of a hinge between the second link 5 and the third link 6 and a rotation center of a hinge between the second link 5 and the fourth link 7, the third link 6 and the fourth link 7 are arranged at intervals in a lateral direction of the column 1, upper ends of the third link 6 and the fourth link 7 are respectively connected to both ends of the first link 4 by hinges, middle portions of the third link 6 and the fourth link 7 are respectively connected to both ends of the second link 5 by hinges, and lower ends of the third link 6 and the fourth link 7 are connected to the sensor 3 mounting member 2 by hinges.

In this way, the sensor mount 2 itself can rotate about the axis p of the rotary shaft 8. Since the sensor mounting member 2 can rotate around the first rotation axis L1 and the axis p, the sensor 3 can swing in two degrees of freedom, when the sensor 3 contacts with the skin of a human body, a pressure value signal can be obtained, and then the pressure sensing surface is controlled by the driving device to be adjusted to a reasonable angle according to the pressure value signal, so as to obtain a more accurate pulse condition signal. Moreover, the rotation around the rotation axis p is a passive mode, a driving mechanism is not needed, and the structure of the mechanical finger is simplified.
