In this case, through adopting the mode that will test the tool range upon range of to the multiunit bear and have the test tool of waiting to test the response product three-dimensional storage in test box, realize single to the response product test of batch to very big improvement response product test efficiency, and then improve production efficiency greatly, reduce workman intensity of labour, simultaneously, through making the first range upon range of feed mechanism and the second range upon range of feed mechanism's direction of delivery each other be reverse mode, realize test box output and accomplished the test tool of test and input the test tool of waiting to test simultaneously, greatly reduced the time of going up the unloading, further improved test efficiency.

The foregoing is merely exemplary of the present utility model and is not intended to limit the present utility model. Various modifications and variations of the present utility model will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, or the like, which is within the spirit and principles of the present utility model, should be included in the scope of the claims of the present utility model.
