Accordingly, the components such as the measuring unit 2, the display device 5, the battery 4, the first wiring board 550, the second wiring board 552, and the key 551 are assembled on the holder 1 to form a core body 10, and the core body 10 is assembled as a whole into the constant diameter cavity 511 of the first housing 510. Since the measuring section 2, the display device 5, the wiring boards 550, 552, and the like are positioned in the holder 1, when the holder 1 is assembled into the first housing 510, the gap 301 is always present between the measuring section 2 and the first housing 510. After the bracket 1 is assembled to a predetermined position in the first housing 510, the display device 5 faces the first housing through hole 516, and the second circuit board 552 faces the second housing 530 through hole. The front end 541 of the bracket 1 is provided with a radial flange 546 and a first projection 547, the first projection 547 being shape-matched to the first notch 518.

When the bracket front 541 is located at the housing first end 512, the radial flange 546 is in close contact with the sidewall of the first opening 514, such that the bracket front 541 is tightly fitted with the first opening 514 to laterally position the bracket front 541 with respect to the first housing 510; the first protrusion 547 snaps into the first notch 518 to form a stop that limits continued movement of the bracket 1 within the cavity 511. The second housing 530 is connected to the rear end 542 of the bracket 1 via a fastener 531, the second housing 530 is flush with the end face of the second end 513 of the first housing 510, and the second protrusion 532 is located in the second notch 519 such that the second housing 530 abuts against the housing, thereby achieving axial (along the length of the first housing 510) limitation of the bracket 1 together with the first protrusion 547. Accordingly, the inner core body 10 is assembled and fixed into the outer shell 3. And by removing the fastener 531 and the second case 530, the inner core body 10 can be pushed out from the first case 510, and the detachable assembly of the bracket 1 and the first case 510 can be achieved.
