Sample adding assembly and sample adding equipment

The utility model relates to the technical field of detection instruments, and discloses a sample adding assembly and sample adding equipment. The sample adding assembly comprises a support, a first fixing plate, an injector fixedly connected to the bottom of the first fixing plate, a TIP head, a separation plate arranged between the TIP head and the injector and a first driving device, and the first driving device can drive the first fixing plate to drive the injector to move in the axial direction of the injector; a through opening is formed in the position, corresponding to the injector, ofthe separation plate, and the injector can penetrate through the through opening to be in butt joint with the TIP head; when the TIP head moves upwards, the separation plate can abut against the TIPhead so as to separate the TIP head from the injector. Because the separation plate can separate the TIP head from the injector in the process that the injector returns to the initial position, an external system or manual wor
