[0040] Please refer to Figure 3 , the test host 1 further comprises a retreat prevention mechanism 19 connected to the moving seat 13, which is used to limit the movement of the trolley 2 in the opposite direction of the first direction X after the trolley 2 and the test host 1 are inserted into each other in the first direction X, so as to prevent the phenomenon of liquid leakage caused by the separation of the integrated board 21 and the docking board 10 when the trolley 2 is pulled out in the opposite direction of the first direction X during the test. Please refer to Figure 4 , the retreat prevention mechanism 19 specifically comprises a fixed seat 191, an elastic member 192 and a retreat prevention block 193, wherein the fixed seat 191 is fixed on the moving seat 13, the retreat prevention block 193 is in sliding connection with the fixed seat 191 in the vertical direction, and the elastic member 192 is connected between the retreat prevention block 193 and the fixed seat 191. The elastic member 192 is preferably a spring, and the retreat prevention block 193 has a movement tendency of being popped up relative to the fixed seat 191 under the elastic force of the elastic member 192. During the process of inserting the trolley 2 and the test host 1 into each other in the first direction X, the trolley 2 will press the retreat prevention block 193 to move downward, and when the trolley 2 is moved to the position, the retreat prevention block 193 will be popped up upward due to the elastic force of the elastic member 192. At this time, the retreat prevention block 193 is arranged in the path of the trolley 2 moving in the opposite direction of the first direction X, so that the trolley 2 cannot be pulled out in the opposite direction of the first direction X due to the limitation of the retreat prevention block 193. Preferably, the top of the retreat prevention block 193 is provided with a first inclined surface 1931 inclined downward in the opposite direction of the first direction X, and the first inclined surface 1931 is arranged in the path of the trolley 2 moving in the first direction X. Specifically, it can be understood that during the movement of the trolley 2 in the first direction X, the trolley 2 will press the first inclined surface 1931 to compress the elastic member 192 downward, that is, the retreat prevention block 193 is more easily driven to move downward by the trolley 2. In other embodiments, an inclined surface can also be arranged on the position of the trolley 2 facing the retreat prevention block 193, which also achieves the purpose of driving the retreat prevention block 193 to move downward.

After the product is tested, the first driver 12 drives the moving seat 13, the stop mechanism 19, the second driver 14 and the rotating block 15 to jointly move along the reverse direction of the first direction X. When the stop block 193 hits the unlocking block 20, the unlocking block 20 pushes the stop block 193 to compress the elastic member 192 downward until the stop block 193 no longer limits the position of the trolley 2 along the reverse direction of the first direction X. At this time, the trolley 2 can be pulled out along the reverse direction of the first direction X. Preferably, the side of the unlocking block 20 facing the stop block 193 is provided with a second inclined surface 201 inclined downward, which is arranged on the path of the reverse movement of the stop block 193 along the first direction X. During the movement of the stop mechanism 19 along the reverse direction of the first direction X driven by the first driver 12, the stop block 193 is extruded by the second inclined surface 201 to automatically compress the elastic member 192 downward, so as to ensure that the unlocking block 20 can drive the stop block 193 to move downward. In other embodiments, an inclined surface can also be arranged on the side of the stop block 193 facing the unlocking block 20, which can also achieve the purpose of driving the stop block 193 to move downward.

[0042] The above is only a preferred embodiment of the present application, and only the technical principle of the present application is specifically described. These descriptions are only for explaining the principle of the present application, and cannot be explained as the limitation of the protection scope of the present application in any way. Based on the explanation herein, any modification, equivalent replacement and improvement within the spirit and principle of the present application, and other specific embodiments of the present application which can be thought by those skilled in the art without creative labor, should be included in the protection scope of the present application.
