Detailed Description

The utility model will be further described with reference to specific embodiments shown in the drawings.

Referring to fig. 5-8, a jack anchor plate connecting structure comprises an anchor plate 1 and a large piston 2, wherein the anchor plate 1 is positioned at the front end part of the large piston 2, the anchor plate 1 is movably connected with the large piston 2, specifically, the anchor plate 1 can freely rotate, a pressing block 3 is arranged at the end part of the large piston 2, and a limiting structure for limiting the anchor plate 1 to be separated from the large piston 2 is arranged between the pressing block 3 and the anchor plate 1. The end part of the large piston 2 is provided with a mounting groove 5, one end of the anchor plate 1 is inserted into the mounting groove 5, and the bottom surface of the mounting groove 5 is matched with the end surface of the insertion end of the anchor plate 1.

The anchor plate 1 is provided with an annular boss 4, the pressing block 3 is an annular cover body and is sleeved on the periphery of the anchor plate 1, and the pressing block 3 is provided with a contact surface matched with the annular boss 4. Of course, the bosses 4 may not be annular, and the number of the bosses 4 may be 2, 3 or more, and the bosses 4 are arranged at regular intervals around the axial line of the anchor plate 1.

The press block 3 and the large piston 2 can be detachably connected.

In one embodiment, the pressing block 3 is in threaded connection with the large piston 2, as shown in fig. 5, an internal threaded hole 6 is formed in one side, close to the end portion of the large piston 2, of the pressing block 3, an external threaded section corresponding to the internal threaded hole 6 is formed in the end portion of the large piston 2, the internal threaded hole 6 is screwed in the external threaded section, and the bottom end face of the internal threaded hole 6 is matched with the boss 4 to limit the anchor plate 1.
