Because the initial position of the pulling rope 515 has a certain looseness, when the second push rod 513 starts to be pushed, the second push rod 513 cannot be directly pulled through the pulling rope 515, at this time, the second push rod 513 drives the rectangular shell 517 to move, the fourth spring 522 drives the moving limiting block 519 to move together, until the pulling rope 515 is tightened in the pushing process, and at this time, the pin 802 is already located at a position above the bottom surface of the side limiting block 521. When the second push rod 513 is pushed continuously, the rectangular shell 517 drives the two side limiting blocks 521 to move continuously, the pulling rope 515 pulls the pulling rod 5195 to move upwards in the circular through hole, due to the existence of the fourth spring 522, the moving limiting block 519 cannot be pulled firstly, the pulling rod 5195 drives the pulling plate 5193 to move upwards, the two second rotating plates 5192 are forced to rotate and open, the two rotating wiping plates 5191 are driven to rotate and open until the pulling rod 5195 is pulled to the highest position, and the fifth spring 5194 is compressed to the limit position. At this time, the two pins 802 at the two sides are respectively located between the side wiping plate 521 and the moving stopper 519, the pin 802 at the middle part is located between the two moving stoppers 519, and the bottom of the pin 802 is held by the rotating wiping plate 5191. After that, the second push rod 513 is continuously pushed, the rectangular shell 517 continuously drives the two side limiting blocks 521 to move downwards, meanwhile, after the pulling rod 5195 is pulled by the pulling rope 515 to the extreme position, the whole moving limiting block 519 is continuously pulled to move upwards relatively in the rectangular shell 517, the actual position of the moving limiting block 519 is kept unchanged due to the limitation of the pulling rope 515 and is flush with the position opposite to the protective sleeve 9, and the subsequent protective sleeve can be conveniently inserted.

When the pulling string 515 pulls the moving stopper 519 to compress the fourth spring 522 until the second push rod 513 is pushed to the maximum position, the two pins 802 at the two sides are clamped between the side stoppers 521 and the moving stopper 519, the rotating wiping plate 5191 and the rectangular shell 517, and the pin 802 at the middle is clamped between the two moving stoppers 519 and the two rotating wiping plates 5191 and the rectangular shell 517. In this process, if the lead 802 is skewed, the position of the end of the lead 802 is constrained by being pressed by the rectangular housing 517 and finally pressed against the rotating wiper plate 5191.

The pulling rope 515 is slightly loosened in the initial state, the side limiting blocks 521 face one side of the moving limiting block 519, the two ends of the lower end of the moving limiting block 519 on the same side with the rotating wiping plate 5191, and the positions of the rectangular shell 517 between each two side limiting blocks 521 and the moving limiting block 519 or between two moving limiting blocks 519 are all provided with wiping layers 523. After the end positions of the three pins 802 are defined, the first push rod 503 is pushed to drive the protective sleeve 9 to move towards the rectangular housing 517, the three pin placing cavities 902 of the protective sleeve 9 are respectively sleeved with the three pins 802, in the process, the front end of the protective sleeve 9 pushes the side limiting blocks 521 and the side surfaces of the moving limiting blocks 519 in the process of being sleeved on the pins 802, so that the whole rectangular housing 517 drives the second sliding housing 512 to move together, the third springs 516 are stretched, and in the process that the rectangular housing 517, the side limiting blocks 521 and the moving limiting blocks 519 move together, the wiping layer 523 thereon continuously wipes the pins 802 before the pins 802 enter the pin placing cavities 902 of the protective sleeve 9, dirt or moisture which may be originally carried on the pins 802 is wiped off, and the pins 802 are prevented from being brought into the protective sleeve 9. Meanwhile, in the process that the rectangular shell 517, the side limiting block 521 and the movable limiting block 519 are pushed together, the vertical position of the rectangular shell 517 is kept constant, and the rectangular shell 517 only moves in the horizontal position, and if the middle part of the pin 802 is bent and crazy, the rectangular shell 517, the side limiting block 521 and the movable limiting block 519 are continuously straightened when moving in a small space surrounded by the rectangular shell 517, the side limiting block 521 and the movable limiting block 519 before entering the protective sleeve 9. The pins inserted into the protective sleeve 9 are ensured not to bend and skew, and the quality of the electronic element 8 is ensured to be higher.

When the protective sleeve is sleeved, the second push rod 513 is pushed away, the second push rod 513 resets, the pulling rope 515 pulls the pulling rod 5195 away, the pulling rod 5195 resets under the action of the fifth spring 5194, the first push rod 503 resets under the action of the first spring 509, the second sliding shell 512 resets under the action of the third spring 516, and the installation process of the protective sleeve 9 is finished once.
