[0021] The present invention effectively avoids the problem of low detection efficiency caused by frequent replacement of probes by setting a multi-joint installation mechanism and a switching mechanism. The first rotating shaft is driven to rotate by manually rotating the handle, which drives the cam fixed on the outside thereof to rotate and the lever connected to the guide plate. After the cam rotates, the first connecting plate in the connecting rod assembly is pressed down to make the second connecting plate, the third connecting plate, the fourth connecting plate and the push seat realize upward arc shifting, so as to link the push plate and the lifting frame to lift and lower. At the same time, the guide plate at the end of the first rotating shaft drives the lever to be embedded in the shifting groove of the semicircular ball, and the support column and the overhead platform are driven to rotate, so that the target interface probe is aligned with the interface outlet at the top of the shell body, so as to facilitate the signal detection of the LED display screen of the optoelectronic device. When the overhead platform rotates, the positioning card block 209 and the I-shaped card block 207 in the interface card slot adaptively clamp different interface probes through the first spring, and cooperate with the first gear, the second gear and the pointer in the display assembly to conveniently display and indicate the current interface type, so as to realize fast switching and precise positioning of multiple interfaces, without disassembling and replacing the probe, and significantly improve the detection efficiency and portability.

[0022] Through the positioning mechanism provided in the present invention, the problem of signal detection failure caused by poor contact or loose clamping of the probe is effectively avoided. When the interface probe rotates with the overhead platform to the interface outlet, the cam drives the lifting frame to move upward through the connecting rod assembly, drives the inclined block in the positioning frame to rise by jacking up the top block, and the inclined edge of the inclined block pushes the clamping plate to clamp the I-shaped block at the bottom of the interface probe head. Then, it can protrude from the positioning frame and jack up the interface probe. Moreover, an elastic conduction needle is connected inside the interface probe, which can improve the connection strength and avoid damaging the interface due to excessive extrusion. After the detection is completed, the cam resets, the lifting frame moves downward, the inclined block retracts under the action of the third spring, the clamping plate releases the interface probe again, and then enters the interface card slot, and the interface probe is clamped again by the positioning block.

[0024] Through the... provided in the present invention, the problems of winding, damage and inconvenient storage of the detection line are effectively avoided. The wire of the interface probe extends to the winding and unwinding reel inside the base through the wire groove inside the overhead platform and the support column. When the probe is pulled out for use, the winding and unwinding reel rotates as the wire extends, and the torsion spring stores elastic potential energy. After the detection is completed, the probe is released, and the torsion spring releases energy to drive the winding and unwinding reel to rotate in the reverse direction, automatically winding the wire into the fixed seat to avoid the wire being exposed and wound or bent and damaged, while reducing the manual sorting time and ensuring the portability of the device and the convenience of the next use.

During installation, the I-shaped blocks 207 at the bottom of the interface probe 206 are aligned with the openings of the interface card slots 205, and the probe is pressed downward. The I-shaped blocks 207 squeeze the positioning blocks 209 on both sides, causing the positioning blocks 209 to expand outward against the elastic force of the first springs 210. When the I-shaped blocks 207 completely enter the card slots, the first springs 210 rebound and push the positioning blocks 209 to contract inward, clamping the grooves of the I-shaped blocks 207 to achieve the stable installation of the probe. When the probe needs to be replaced, press the outer ends of the positioning blocks 209 to make them expand, and the probe can be easily taken out. Through this structure, multiple interface probes 206 are fixed on the suspension platform 203 in a circular array. Combining with the rotation function of the support column 201, different interface types can be quickly switched.
