[0012] In a preferred embodiment, a handle is installed on the top of the box cover, and the connection between the handle and the box cover makes it convenient for an operator to hold the handle to open or close the box cover.

[0013] Technical effects and advantages of the utility model:

[0014] By using the rebound force of the spring, the two clamps can move inward to clamp and fix the reagent tube.
