Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1 to 6, it includes a connector 20 and a bolt 30 combined with the screw connector 12 of a jack 10; the connector 20 is configured to have a sleeve connector 21 and two pivoting pieces 23, the sleeve connector 21 is configured to have a square sleeve hole 22, the sleeve connector 21 is configured to have a twelve-star shape 211, four corners of the sleeve hole 22 are respectively provided with an enlarged arc angle 221, the two pivoting pieces 23 are respectively provided with a shaft hole 24 to penetrate, and a cutting groove 25 is formed between the two pivoting pieces 23; and a hole groove 301 is dug at the side of the shaft bolt 30, and a spring 31 and a steel ball 32 are sequentially placed in the hole groove 301, so that the steel ball 32 can be elastically embedded in the hole opening of the hole groove 301 without being separated.
Through the jack connection structure, the following effects and advantages can be obtained: as shown in fig. 1 and 2, when the screw joint 12 of the jack 10 is in the form of two pivoting pieces 13, the two pivoting pieces 23 of the joint 20 can be inserted into the combination slots 14 of the two pivoting pieces 13 of the jack 10, and the shaft pin 30 combines the two pivoting pieces 23 of the joint 20 and the two pivoting pieces 13 of the screw joint 12 into a whole through the shaft hole 24; the steel ball 32 can be elastically forced to compress the spring 31 to pass through the shaft hole 24, and the steel ball 32 can prevent the shaft bolt 30 from being mistakenly separated, thereby achieving the effect of easy assembly.
As shown in fig. 4 and 5, when the screw joint 12 of the jack 10 is a single pivoting piece 15, the slot 25 between the two pivoting pieces 23 of the joint 20 is used for inserting the single pivoting piece 15 of the screw joint 12, and the shaft pin 30 combines the two pivoting pieces 23 of the joint 20 and the single pivoting piece 15 of the screw joint 12 into a whole through the shaft hole 24.
