[0035] In the present invention, the first fixture platform 22 can meet the requirements for fixed measurement of products of different sizes.

[0036] like Figure 4 As shown, in one embodiment, the normal temperature detection mechanism 30 includes a support frame 31 provided on the operating table 100, and a second clamping mechanism 32 mounted on the support frame 31.

The frame 321 is mounted on the support frame 31, and the two clamping plates 323 are respectively and symmetrically slidably mounted on the second linear guide rail set.

[0037] The clamping plate 323 is symmetrically provided with two sliding blocks 3231 in the transverse direction and a positioning column 3232 in the longitudinal direction. The two sliding blocks 3231 and the positioning column 3232 form a triangular structure.

[0038] Among them, the lifting assembly includes a driving screw rod 3241, a driven screw rod 3242, a first gear 3243, a second gear 3244 and an operating handle 3245; the driving screw rod 3241 and the driven screw rod 3242 are respectively connected to the upper and lower ends of the frame body 321 through two clamping plates 323; the first gear 3243 is threadedly connected to the driving screw rod 3241, and the second gear 3244 is installed on the frame body 321 and is located on one side of the first gear 3243, and the first gear 3243 is engaged with the second gear 3244; the operating handle 3245 is connected to the second gear 3244.

[0039] The upper and lower ends of the driving screw 3241 and the driven screw 3242 are connected to the frame 321 via shaft seats. The second linear guide assembly consists of four second linear guides 322, which are symmetrically distributed on the left and right inner walls of the frame 321. The operating handle 3245 includes a manual turning handle and a connecting rod connecting the manual turning handle to the second gear 3244. The manual turning handle is located outside the frame 321, and the connecting rod passes through the side wall of the frame 321 and connects to the second gear 3244.

[0040] Specifically, both the first gear 3243 and the second gear 3244 are bevel gears, which can ensure high control accuracy. The operating handle 3245 is used to drive the second gear 3244 to rotate, which in turn drives the first gear 3243 to rotate. The first gear 3243 drives the driving screw 3241 and the driven screw 3242 to move up and down, thereby driving the clamping plate 323 to move up and down.

[0041] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
