A pressure member 7 for applying pressure to the pressure sensor 5 is fixedly mounted on the lower end of the mounting plate 6.

[0026] In this embodiment, the linear drive mechanism 4 includes a drive motor 41, a bearing seat 42, a lead screw 43, and a slider 44. The drive motor 41 is fixedly mounted on the inner bottom surface of the housing 2, and the bearing seat 42 is fixedly mounted on the inner top surface of the housing 2.
