A connecting frame 46 is fixedly connected to the top of the electric push rod 45. A pressing plate 47 is fixedly connected to the bottom of the connecting frame 46.

[0031] Clamping rings 22 are respectively fixedly connected to both ends of the probe placement plate 2, and the clamping rings 22 are respectively sleeved on the placement racks 44.

[0032] Multiple groups of placement grooves 21 are provided, and every three of the multiple groups of placement grooves 21 form a group.

[0033] The lifting block 43 is slidably arranged in the lifting groove. The top of the first lead screw 42 movably penetrates through the vertical rod 4 and is fixedly connected to the first motor 41, and the bottom of the first lead screw 42 is movably connected to the inner bottom wall of the lifting groove.

[0034] Contact points 31 are arranged on the top of the test bottom plate 3, and the number of the contact points 31 corresponds to that of a group of placement grooves 21.

[0035] Through the above technical solution, the probe placement plate 2 is used to place the spring probes to be tested, and the test bottom plate 3 is used for actual test work. A series of placement grooves 21 are formed at the top of the probe placement plate 2 for fixing and positioning the spring probes to be tested. Driven by the first motor 41, the first lead screw 42 rotates, thereby driving the lifting block 43 to move up and down in the lifting groove of the vertical rod 4, so that the spring probes in the placement grooves 21 move downward to abut against the contact points 31 on the test bottom plate 3. The electric push rod 45 can control the height of the connecting frame 46 and the pressing plate 47 to fix the spring probes in the placement grooves 21.

[0039] Through the above technical solution, driven by the second motor 51, the second lead screw 52 will rotate, thereby driving the moving block 53 to move left and right in the transverse groove of the cross bar 5. In this way, the position of the test bottom plate 3 can be adjusted, so that the contact points 31 on the top of the test bottom plate 3 can sequentially test the spring probes in each group of placement grooves 21, with strong automation.

[0040] During the actual operation process, when this device is in use, the spring probes to be tested are respectively placed into the placement grooves 21. The snap rings 22 at both ends of the probe placement plate 2 are sleeved on the placement frame 44. The electric push rod 45 controls the height of the connecting frame 46 and the pressing plate 47 to fix the spring probes in the placement grooves 21.

When there are defects in the spring probes, the first motor 41 and the electric push rod 45 are controlled to reset, and the defective spring probes are taken out. Subsequently, the above operations are performed to sequentially test the remaining multiple groups of spring probes.
