The proximal ends of the two push springs 12 are fixedly connected to the far ends of the two limit plates 10 respectively. The two push springs 12 are respectively arranged in the inside of the two placement grooves 8. The push springs 12 are designed to facilitate pushing the limit plates 10, thereby pushing the blocking block 9 so that the blocking block 9 is engaged in the inside of the slot 7.

When the sucker rod 2 and the lifting connector need to be disassembled, the pulling ring 13 is pulled by hand, thereby pulling the limiting plate 10 and the card The block 9 is pushed away from the inside of the card slot 7, and the connecting seat 2 4 can be removed from the connecting seat 1 at this time. The block 9 is tightly engaged with the card slot 7 under the push of the push spring 12 and the limit plate 10, so that the lifting connector and the sucker rod 2 can be fixed without using special tools. The operation is simpler and can be installed in less time, which reduces the complexity of the operation and the possibility of loosening. When it is necessary to reinforce the sucker rod 2 in the lifting connector, the swivel 17 is turned by hand so that the swivel 17 can drive the cylinder 16 and the rotating plate 15, thereby pushing the fixing block 14 to fit tightly with the sucker rod 2, so that the sucker rod 2 can be more tightly connected to the connector, thereby improving the stability and reliability of the connection.
