On this basis, this application still is equipped with first spacing convex part in both of turnbuckle arch 42 and turnbuckle draw-in groove 41, another one of them is equipped with first spacing concave part, as shown in fig. 3 through 5, this application schematically shows that turnbuckle arch 42 is equipped with first spacing convex part 421, the embodiment that turnbuckle draw-in groove 41 is equipped with first spacing concave part 411, first spacing concave part 411 and first spacing convex part 421 cooperate in the vertical direction in order to restrict the relative rotation between upper cover assembly 3 and juice glass 2 when upper cover assembly 3 upwards moves, namely the cooperation of first spacing concave part 411 and first spacing convex part 421 realizes the restriction to upper cover assembly 3 pivoted degree of freedom when upper cover assembly 3 takes place upwards, upper cover assembly 3 is locked along the rotation of horizontal direction, in case juice extractor head work in-process through fruit vegetables with upper cover assembly 3 upwards jack-up or juice extractor head counter-rotating descends, also can not drive upper cover assembly 3 and take place to rotate, upper cover assembly 3 is avoided and is driven to rotate under juice extractor head's rotatory effect, make juice extractor rotation steady and more normal steady operation. When the juice extraction is finished, after the juice extraction head descends, the upper pressing force on the upper cover assembly 3 is relieved, the upper cover assembly 3 automatically falls back, the cooperation of the first limit concave part 411 and the first limit convex part 421 is relieved, and the upper cover assembly 3 can be normally rotated and opened.

As a preferred embodiment of the present application, one of the turnbuckle protrusion 42 and the turnbuckle clamping groove 41 may be provided with a second limit protrusion, and the other one of the turnbuckle protrusion and the turnbuckle clamping groove is provided with a second limit recess, and the second limit protrusion and the second limit recess cooperate in a radial direction of the juice cup 2 to limit the relative rotation between the upper cover assembly 3 and the juice cup 2.

As shown in fig. 3 and 4, the present application schematically illustrates an embodiment in which the turnbuckle protrusion 42 is provided with a second limit concave portion 422, and the turnbuckle clamping groove 41 is provided with a second limit convex portion 412. The second limiting convex part 412 and the second limiting concave part 422 are matched in the radial direction of the juice glass 2 to limit the relative rotation between the upper cover assembly 3 and the juice glass 2, so that the rotation of the upper cover assembly 3 in the horizontal direction is further limited, the fastening performance of the turnbuckle connection between the turnbuckle clamping groove 41 and the turnbuckle protrusion 42 is enhanced by utilizing the matching of the second limiting convex part 412 and the second limiting concave part 422, and the upper cover assembly 3 is not easy to be turned off no matter whether the first limiting convex part 421 and the first limiting concave part 411 are in a turnbuckle matching state or not.

As a preferred embodiment of the present application, a guiding slope for guiding the first limiting protrusion 421 to slide into the first limiting recess 411 may be provided at the first limiting protrusion 421 and/or the first limiting recess 411.

As shown in fig. 4, the present application schematically illustrates an embodiment in which the first limiting protrusion 421 is provided with a guiding slope 423. As can be appreciated by those skilled in the art, during the processing of the positioning structure 4 and during the mounting and matching process of the upper cover assembly 3 and the juice glass 2, a certain processing error and a certain mounting error are unavoidable, so that the first limiting protrusion 421 cannot be precisely located at a right position with the first limiting recess 411 in the vertical direction, and even if a certain error exists, the guiding effect of the guiding inclined plane 423 can also guide the first limiting protrusion 421 to match with the first limiting recess 411 when the upper cover assembly 3 moves up.

As a preferred embodiment of the present application, as shown in fig. 3, an arc-shaped guiding surface 413 for guiding the turnbuckle protrusion 42 to slide into the turnbuckle slot 41 may be further provided at the opening of the turnbuckle slot 41.
