The present invention relates to the field of test devices. The skin prick test device according the present invention mainly comprises conjoined bottles, a tray and pricking devices, wherein each set of conjoined bottles, which comprises a large bottle body and a small bottle body, is arranged in clamping holes of the tray, and liquid medicine can flow into the small bottle body from the large bottle body through an inclined surface, thereby avoiding frequent refilling of the liquid medicine. In addition, each connecting base has a trapezoidal cross section with its bottom surface being flush with that of the holder, and is gradually widened from the top down to fit with the parallel clamp plates on the tray, so that the pricking device has better stability as both ends thereof are prevented from excessively shaking longitudinally when the pricking device is taken out of and put into the tray.
