After the test is completed, the driving component drives the test component to reset, and the tested product can be removed; the present invention can quickly connect the test probe and the test contact, and the entire testing process is simple, convenient and efficient.

[0007] Preferably, the driving assembly includes a fixing frame, a driving handle, a driving rod and a hinge; the fixing frame is connected to the bracket, and the upper end of the fixing frame is provided with a hinge portion, and the lower end is provided with a guide cylinder extending vertically up and down; the driving handle is arranged in an L-shape, and one end thereof is hinged to the hinge portion of the fixing frame; one end of the hinge is hinged to the bend of the driving handle, and the other end is hinged to the upper end of the driving rod, and the lower end of the driving rod passes through the guide cylinder and is connected to the test assembly. The driving assembly of the present invention adopts a multi-link mechanism, and the driving rod can be driven to move vertically up and down by rotating the driving handle, and the guide cylinder can prevent the driving rod from radially deviating.

[0008] Preferably, the test assembly includes a test frame, the test probe is disposed within the test frame, and the contact end of the test probe extends downward to the outside of the bottom of the test frame. During testing, the drive assembly can be used to drive the test frame downward, causing the bottom of the test frame to abut against the top of the product under test on the positioning seat. The test probe then abuts against the test contact, and the test end of the test probe is retractable to avoid damage during abutment.

[0009] Preferably, the test frame is made of a transparent material and is provided with a camera inside for scanning the ID barcode on the product to be tested. Each product to be tested has a unique ID barcode, so that the test information of each product to be tested can be accurately recorded.

[0023] The present invention provides a positioning seat 3 for positioning the product to be tested on the base 1, and then drives the test component 5 to move vertically downward through the driving component 4, so that the test probe abuts against the corresponding test contact, and then presses the signal transmission key to start the component 6 to start the signal transmission key on the side wall of the product to be tested to perform subsequent tests. After the test is completed, the driving component 4 drives the test component 5 to reset, and the tested product can be removed; the present invention can quickly connect the test probe and the test contact, and the entire testing process is simple, convenient and efficient.

[0024] Among them, the driving component 4 includes a fixing frame 41, a driving handle 42, a driving rod 43 and a hinge 44; the fixing frame 41 is connected to the bracket 2, and the upper end of the fixing frame 41 is provided with a hinge part 411, and the lower end is provided with a guide cylinder 412 extending vertically up and down; the driving handle 42 is arranged in an L shape, and one end thereof is hinged to the hinge part 411 of the fixing frame 41; one end of the hinge 44 is hinged to the L-shaped bend of the driving handle 42, and the other end is hinged to the upper end of the driving rod 43, and the lower end of the driving rod 43 passes through the guide cylinder 412 and is connected to the test component 5.
