[0025] The chip loading assembly 6 includes a loading test chamber 61, a material carrying drawer 62, and a drawer driving assembly. An outlet for the material carrying drawer 62 to enter and exit the loading test chamber 61 is provided at one end of the loading test chamber 61. The drawer driving assembly includes a drawer driving device 63 and a pulley assembly. The moving end of the drawer driving device 63 is connected to the pulley assembly. The material carrying drawer 62 includes a material carrying plate and a chamber door cover plate. The material carrying plate is placed on the pulley assembly, and the pulley assembly can support the material carrying plate. Moreover, the drawer driving device 63 drives the pulley assembly to drive the material carrying drawer 62 to enter and exit the loading test chamber 61.

[0026] Through the cooperation of the material carrying drawer 62 and the pulley assembly, the pulley assembly is installed inside the device loading test chamber 61, and the pulley assembly supports the material carrying drawer 62. When the chamber needs to be opened, the drawer driving device 63 drives the pulley assembly to rotate. Through the friction force between the pulley assembly and the lower end of the material carrying plate, the material carrying drawer 62 is pushed out from the outlet direction, realizing the automatic pushing out and retracting of the material carrying drawer 62.

[0027] Meanwhile, a pulling notch is provided at the lower end of the chamber door cover plate. The setting of the pulling notch enables the user to reach into the pulling notch to pull out the material carrying drawer 62 when the drawer driving device 63 is damaged and unable to automatically push out the material carrying drawer 62, realizing the loading of the biochip.

[0028] The pulley assembly includes a first pulley 64, a second pulley 65, and a linkage rod 66.
