[0015] Beneficial Effects

[0016] 1. The present invention cooperates with the oil pumping mechanism, the oil pumping cylinder and the oil storage box, so that the motor on the plug-in and pull-out test machine body can rotate with the cam while the motor is running, and then the rotating cam and the external spring of the transverse guide rod cooperate to make the movable plate move back and forth with the piston rod and the piston, so that suction is generated inside the oil pumping cylinder, the lubricating oil inside the oil storage box is sucked and transported to the oil delivery hose, and then the lubricating oil is transported to the inside of the two sliding cylinders through the oil delivery hose, and then the lubricating oil flows to the outside of the guide rod, so that the sliding cylinder and the guide rod can be effectively lubricated, thereby greatly reducing the wear on the sliding cylinder, thereby improving the stability of the movable support plate when it moves back and forth, and then effectively avoiding the deviation phenomenon between the computer connection line plug and the plug interface of the plug-in and pull-out detection, thereby improving the detection quality.

[0017] 2. The present invention, through the provision of an oil collecting box and an oil collecting box, can allow the lubricating oil that has flowed to the outside of the guide rod for lubrication to drip into the oil collecting box under the action of gravity, and then flow back into the oil collecting box after being filtered through the filter screen on the oil collecting box, completing a cycle, thereby effectively avoiding the phenomenon of excessive loss of lubricating oil, thereby reducing the lubrication cost of the detection equipment during detection.

[0018] 3. The present invention installs a cleaning brush on the bottom end surface of the movable support plate, and the bristles of the cleaning brush are in close contact with the bottom end surface of the inner part of the oil collecting box. When the movable support plate moves back and forth, the cleaning brush can be moved back and forth together with the cleaning brush, so that the debris filtered out from the surface of the filter net on the oil collecting box can be automatically cleaned up, thereby effectively avoiding the clogging of the filter net on the oil collecting box and improving the reliability of oil return.

[0019] 4. The present invention can quickly adjust the telescopic length between the connecting tube and the sliding rod as needed through the cooperation between the plug-in part and the adjusting socket on the sliding rod. When adjusting, it is only necessary to grip the front end of the T-shaped pull rod toward the inner front side of the U-shaped auxiliary grip rod, so that the T-shaped pull rod can move forward with the sliding block and the limiting plug rod, so that the limiting plug rod is pulled out from one of the adjusting sockets on the sliding rod, so that the sliding rod loses its limiting effect inside the connecting tube, and then the telescopic length between the connecting tube and the sliding rod can be adjusted, thereby greatly improving the flexibility of the detection equipment when used.

[0045] Specific usage and function of this embodiment: In the present invention, when testing the quality of the computer cable plug before leaving the factory, firstly, the computer cable plug is clamped and fixed to a clamping mechanism 7 on the right side. When clamping, the computer cable plug is placed between the two clamping blocks 703. Then, the clamping screw 702 is manually rotated, so that the two threaded barrels 704 move in opposite directions with the two clamping blocks 703 at the same time under the action of two reverse threads at the outside of the clamping screw 702, so as to clamp and position the computer cable plug. Then, the plug interface of the computer cable plug to be tested is clamped and positioned on a clamping mechanism 7 on the left side.

[0046] Then the plug-in and unplug-out test machine body 1 is started, so that the motor on the plug-in and unplug-out test machine body 1 drives the driving disk 101 to rotate, and then the driving disk 101 drives the right end of the connecting tube 201 to rotate, and then the left end of the sliding rod 202 drives a clamping mechanism 7 on the right side to move back and forth left and right, thereby driving the computer connecting cable plug to move back and forth left and right, so that the computer connecting cable plug completes the reciprocating plug-in and unplug-out test, so that the quality of the computer connecting cable plug before leaving the factory can be tested;

The testing machine body (1) is started, so that the motor on the plug-in / plug-out testing machine body (1) drives the driving disk (101) to rotate, and then the driving disk (101) drives the right end of the connecting tube (201) to rotate, and then the left end of the sliding rod (202) drives a clamping mechanism (7) on the right side to move back and forth left and right, thereby driving the computer connecting cable plug to move back and forth left and right, so that the computer connecting cable plug completes the reciprocating plug-in / plug-out test, so that the quality of the computer connecting cable plug before leaving the factory can be tested; while the motor on the plug-in / plug-out testing machine body (1) is in operation, the cam (803) is driven to rotate through the rotating shaft on the driving disk (101), and then the cam (803) is driven to rotate through the rotating shaft on the driving disk (101), and then the cam (803) is driven to rotate through the rotating shaft on the driving disk (101). The protrusion of the cam (803) pushes the movable plate (802) backward, and then the movable plate (802) moves backward with the piston rod (805) and the piston (806). Then the protrusion of the cam (803) continues to rotate, causing the movable plate (802) to lose its thrust. Then, the movable plate (802) at this time moves forward with the piston rod (805) and the piston (806) under the action of the external spring of the transverse guide rod (804). Then, the forward moving piston (806) forms a negative pressure inside the pumping cylinder (9), and then the lubricating oil inside the oil storage box (102) is sucked into the inside of the pumping cylinder (9) through the oil suction port of the pumping cylinder (9). Then, when the piston (806) moves backward, the lubricating oil extracted from the oil pump (9) is pushed into the oil delivery hose (10), and then the lubricating oil is delivered to the inside of the two sliding cylinders (501) through the oil delivery hose (10), and then the lubricating oil flows to the outside of the guide rod (401), so that the sliding cylinder (501) and the guide rod (401) can be effectively lubricated, thereby greatly reducing the wear of the sliding cylinder (501), thereby improving the stability of the movable support plate (5) during reciprocating movement, and effectively avoiding the deviation between the computer connection line plug and the plug interface during plug-in and unplug detection, thereby improving the detection quality. ;
