[0036] Fruits are loved by people because they are rich in various vitamins and contain a lot of water. However, fruits like passion fruit are not convenient to be eaten directly after being shelled. In order to make it easier for the elderly and children to eat, fruits are generally squeezed into various juices, which make the nutrients easier to absorb. However, juicing fruits is very inconvenient and requires a lot of effort, especially in juice production factories, where the amount of juice squeezed is huge. The traditional way of juicing is generally to squeeze out the juice by squeezing the fruit body, but the squeezing is insufficient, resulting in a great waste of the fruit body, and the pulp inside the fruit body is also discarded, resulting in a serious loss of nutrients.

Specifically, a plurality of the stirring connecting rod structures are arranged along the circumference of the stirring shaft body 21; when the plurality of the stirring connecting rod structures extend into the fruit body for stirring, the plurality of the stirring connecting rod structures move away from each other to be in an expanded state, so as to open and stir the flesh in the fruit body; when the plurality of the stirring connecting rod structures are separated from the fruit body, the plurality of the stirring connecting rod structures move closer to each other to be in a contracted state, so that the stirring head 22 contracts to facilitate movement and to separate from the fruit body. The stirring shaft body 21 is driven to rotate by the stirring drive structure, and the plurality of the stirring connecting rod structures are separated from each other under the action of centrifugal force, so that the stirring area is larger, so as to fully stir the flesh in the fruit body and extract the juice; after the stirring is completed, the stirring shaft body 21 stops rotating, and the plurality of the stirring connecting rod structures move closer to each other to contract, so as to facilitate the stirring head 22 to escape from the fruit body.

[0040] Furthermore, in one embodiment, the stirring connecting rod structure can be configured such that one end is mounted on the stirring shaft body 21 through a connecting seat, and the other end is a free end. Driven by the stirring shaft body 21, the free ends of the plurality of stirring connecting rod structures are opened for stirring.

[0041] In another embodiment, each of the stirring connecting rod structures further comprises a first connecting seat 221 fixedly sleeved on the stirring shaft body 21, and a second connecting seat 222 slidably sleeved on the stirring shaft body 21 and spaced apart from the first connecting seat 221, the first stirring rod 223 is hinged on the first connecting seat 221, and the second stirring rod 224 is hinged on the second connecting seat 222, so that both ends of the first stirring rod 223 and the second stirring rod 224 are provided with connecting seats, so that the strength of the stirring connecting rod structure is better and not easy to be damaged, and the pulp in the fruit body can be stirred out together, so that the extraction is more thorough and the extraction effect is better. Any one of the first connecting seat 221 and the second connecting seat 222 can be located at the end of the stirring shaft body 21 to extend into the fruit body.
