Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 As shown, a screw lifter with a replaceable connector includes a lifter body 1, and further includes: a cover plate 2 provided on the surface of the lifter body 1, a motor 3 is provided on one side of the lifter body 1, the output end of the motor 3 penetrates into the interior of the lifter body 1 and is installed with a transmission rod 4. The lifter body 1, the cover plate 2, the motor 3, the transmission rod 4 and the screw rod 5 are prior art, and this solution will not be elaborated much. And those skilled in the art can clearly understand the working principle. A screw rod 5 is provided on one side of the transmission rod 4;

[0023] A first clamping ring 6 is arranged at the bottom of the transmission rod 4 and the screw rod 5, and a protective pad 14 is arranged between the first clamping ring 6 and the second clamping ring 7. The material of the protective pad 14 is rubber, which can effectively reduce the vibration and noise in the transmission of the motor and the screw rod. The material of the protective pad 14 is rubber. The second clamping ring 7 is hinged on one side of the top of the first clamping ring 6. The tops of the transmission rod 4 and the screw rod 5 are provided with grooves 12. The setting of the grooves 12 facilitates the connection and driving between the transmission rod 4 and the screw rod 5 through the block 13 when the second clamping ring 7 is installed. The bottom of the second clamping ring 7 is fixedly connected with the block 13, the front side of the first clamping ring 6 is fixedly connected with an extension plate 8, and the top of the extension plate 8 is fixedly connected with a positioning plate Shell 9, the bottom of the inner cavity of the positioning shell 9 is fixedly connected with a spring group 15, and the cooperation between the spring group 15 and the movable plate 16 can facilitate and assist in popping out the first clamping plate 10, the top of the spring group 15 is fixedly connected with the movable plate 16, and a limiting rod 17 is arranged inside the movable plate 16, and the movable plate 16 can be limited to float up and down by the limiting rod 17, the bottom of the limiting rod 17 is fixedly connected to the inner wall of the positioning shell 9, the top of the movable plate 16 is in active contact with the first clamping plate 10, the front side of the second clamping ring 7 is fixedly connected with the first clamping plate 10, and the interior of the positioning shell 9 is installed with a disassembly and assembly component 11 for cooperating with the first clamping plate 10, and the disassembly and assembly component 11 includes a partition 1101 and a limiting hole 1102.

[0024] The partition 1101 is fixed to the interior of the positioning shell 9, and the limiting hole 1102 is opened in the interior of the positioning shell 9. Both sides of the partition 1101 are fixedly connected with second springs 1103, and the two second springs 1103 are fixedly connected to the side away from the partition 1101 with a second clamping plate 1104. The bottom of the second clamping plate 1104 is fixedly connected with a push plate 1105. Pinching the two push plates 1105 drives the second clamping plate 1104 to move. At this time, the second clamping plate 1104 moves on the surface of the sliding rod 1106 and squeezes the second spring 1103. At this time, the second clamping plate 1104 will be separated from the surface of the first clamping plate 10, and then the second snap ring 7 can be opened. The end of the push plate 1105 away from the second clamping plate 1104 passes through the outside of the limiting hole 1102, and a sliding rod 1106 is arranged inside the second clamping plate 1104. The two ends of the sliding rod 1106 are respectively fixedly connected to the inner wall of the positioning shell 9 and the partition 1101.

[0025] Working principle: When the user needs to replace the screw 5 or the connector, first pinch the two push plates 1105 to drive the second clamping plate 1104 to move. At this time, the second clamping plate 1104 is limited to move on the surface of the sliding rod 1106, and at the same time, the second spring 1103 is squeezed. At this time, the second clamping plate 1104 will disengage from the surface of the first clamping plate 10. Then, the spring group 15 will drive the movable plate 16 to rise in a limited manner on the surface of the limiting rod 17, so as to assist in ejecting the first clamping plate 10, facilitating the opening of the second snap ring 7. When the second snap ring 7 is opened, it will also drive the clamping block 13 to disengage from the groove 12. Then, the screw 5 can be taken out, or the first snap ring 6 and the second snap ring 7 can be removed.
