Test light is emitted through the measuring light emission module, and the light passes through the light transmission window into the measuring light receiving module to complete data collection. Then, the motor is started to drive the cam to rotate.

The springs 315 are located on the side of the first mounting block 310 away from the locking rod 316. The slide bracket 314 is fixed inside. A second mounting block 317 is installed, and a second protruding rod 318 is fixedly installed at the bottom of the second mounting block 317. The colorimetric mechanism 3 also includes a mounting plate 301 and several placement slots 304. A mounting bracket 302 is fixedly installed on the top of the mounting plate 301. A turntable 303 is rotatably installed at the bottom of the mounting bracket 302. Several placement slots 304 are installed at equal angles on the top of the turntable 303. A reaction vessel 305 is movably installed on the top of the turntable 303. Light-transmitting windows 306 are provided on both the front and rear sides of the reaction vessel 305.

The test light is emitted by the measuring light emission module 307, and the light passes through the light transmission window 306 to enter the measuring light receiving module 308 to complete data collection. Then, the motor 319 is started to drive the cam 311 to rotate. The intermittent rotation mechanism is formed by the cooperation between the cam 311, the first cam 312, the slide 313, and the turntable 303, so that the cam 311 rotates one revolution and the turntable 303 rotates a certain angle. The rotation is repeated to move several reaction containers 303. 05 is placed between the measuring light emitting module 307 and the measuring light receiving module 308 for testing to achieve the purpose of multiple sets of comparative tests. During the above process, the spring 315 provides a pulling force to the locking rod 316 toward the first protrusion 312, so that the cam 311 drives the first protrusion 312 to rotate into the slide groove 313 and drive the turntable 303 to rotate. When the locking rod 316 disengages from the slide groove 313, the cam 311 drives the first protrusion 312 to disengage from the slide groove 313 to complete the purpose of driving the turntable 303 to rotate.
