[0029] In some embodiments, referring to Figure 1 The number of light source emitting elements 2 is multiple, the light source emitting elements 2 can emit light of different wavelengths, and the clamping block 104 corresponds to the light source emitting element 2 one by one. In the embodiment, the number of the light source emitting elements 2 and the signal receiving elements 3 is three, so that the reagent fluorescence detection device of the utility model can simultaneously detect three reaction cups. The clamping block 104 is located on the side of the detection channel 101 close to the light source emitting element 2, and the clamping plate 102 is located on the side of the detection channel 101 close to the signal receiving element 3.

[0034] In some embodiments, referring to Figure 2 , the side of the clamping block 104 facing the clamping plate 102 is a circular arc surface. In this embodiment, since the side of the clamping block 104 facing the clamping plate 102 is a circular arc surface, the contact mode between the clamping block 104 and the reaction cup is linear contact, which reduces the contact area between the clamping block 104 and the reaction cup, and further reduces the resistance of the reaction cup when passing through the detection channel 101.

[0036] In some embodiments, referring to Figure 5 , Figure 6 and Figure 9 , the clamping plate 102 is provided with a positioning block 112 on the side away from the clamping block 104, and the top of the positioning block 112 is provided with an upper stop block 113; the support frame 1 comprises a base 114 and an upper shell 115, the upper shell 115 is detachably installed above the base 114, the bottom surface of the upper shell 115 is provided with a positioning groove 116 matched with the positioning block 112, and the top surface of the positioning groove 116 is provided with an upper insertion groove 117 for inserting the upper stop block 113. In the embodiment, the number of the positioning blocks 112 is two, which are respectively located at the two ends in the length direction of the clamping plate 102. The support frame 1 adopts a split structure, and the upper shell 115 is fixedly connected with the base 114 by means of screws. The signal receiving member 3 is installed between the base 114 and the upper shell 115.

The operator only needs to open the upper shell 115 to take out the clamping plate 102 from the support frame 1.

The clamping plate 102 is connected with the base 114 and the upper shell 115 at the same time, so that the clamping plate 102 is more firm on the support frame 1.

[0038] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
