[0030] Connecting shaft 100;

[0031] The connecting sleeve 200, the connecting shaft 100 is located in the connecting sleeve 200, a limiting recess is provided in the connecting sleeve 200, and a limiting convex is provided on the connecting shaft 100, the limiting convex extends into the limiting recess and the two can slide relative to each other, so that the connecting shaft 100 can only be extended and retracted along the axial direction of the connecting sleeve 200;

[0032] The shovel head 300 is arranged at the end of the connecting sleeve 200 , and the shovel head 300 can swing relative to the connecting sleeve 200 .

[0033] In this embodiment, the connecting shaft 100 and the connecting sleeve 200 can be relatively contracted, so the shovel can be stirred close to the edge of the pot as much as possible without causing collision between the shovel and the pot wall. Under the premise of ensuring that the shovel is not damaged, the stirring and stir-frying area of ​​the shovel is increased; and the setting of the swingable shovel head 300 allows the shovel head 300 to make adaptive adjustments according to the shape of the pot wall.

[0034] Specifically, a sliding sleeve 201 is fixedly provided at the end of the connecting sleeve 200, and the first end of the sliding sleeve 201 extends into the connecting sleeve 200. The limiting recess includes a square groove 202 with an opening at one end of the first end of the sliding sleeve 201, and the limiting protrusion includes a square rod 101 fixedly provided on the connecting shaft 100, and the square rod 101 extends into the square groove 202. The square rod 101 is plugged into the square groove 202, so that the connecting shaft 100 and the connecting sleeve 200 can only telescopically move but not rotate relative to each other.

[0035] Further preferably, a limit ring 102 is fixedly provided on the connecting shaft 100 , and an elastic member 103 is sleeved on the connecting shaft 100 , and two ends of the elastic member 103 respectively abut against the limit recess and the limit ring 102 .

[0036] In this embodiment, the connecting shaft 100 and the connecting sleeve 200 can be relatively extended and retracted. However, in order to ensure that the shovel head 300 can always be in contact with the pot wall and no hard collision occurs between the two, an elastic member 103 is provided in the connecting sleeve 200. The elastic member 103 can be a spring, and the elastic force of the spring is used to maintain a flexible connection between the shovel head 300 and the pot wall.

[0037] Preferably, in order to prevent the connecting shaft 100 and the connecting sleeve 200 from being relatively disengaged, an abutment ring 104 is provided on the connecting shaft 100, the abutment ring 104 is located inside the connecting sleeve 200, and an abutment nut 203 is provided at the end of the connecting sleeve 200, and a gap is provided between the abutment nut 203 and the connecting shaft 100, so that the abutment ring 104 can be connected by abutment with the abutment nut 203.

[0038] Specifically, a connecting groove 204 is provided at the end of the sliding sleeve 201, and a connecting block 205 is fixedly provided on the shovel head 300. The end of the connecting block 205 extends into the connecting groove 204 and is hinged to the sliding sleeve 201. The groove wall of the connecting groove 204 is in contact with the side wall of the connecting block 205 to achieve swing limiting of the shovel head 300.

[0039] In this embodiment, the shovel head 300 can swing relative to the connecting sleeve 200, that is, the working angle of the shovel head 300 is variable, so the shovel head 300 can make corresponding swing adjustments according to the position or shape of the pot wall it abuts against, so as to make it more adaptable.

[0040] Further preferably, the shovel head 300 includes a shovel surface 301 and a shovel back 302, and there is a step between the shovel surface 301 and the shovel back 302 to form a shovel blade 303, and the shovel blade 303 is arc-shaped. The arc-shaped shovel blade 303 can cut into the food pile more naturally, helping to separate rice grains or other food materials that are stuck together, ensuring that each grain of rice is evenly heated.

[0041] like Figure 5-Figure 8 As shown, a stirring device includes the above-mentioned stirring shovel, the number of stirring shovels is multiple, and also includes a fixed main shaft 400 and a transmission box 401 rotatably connected to the fixed main shaft 400, a fixed gear 403 and a transmission gear 404 that mesh with each other are arranged in the transmission box 401, the fixed gear 403 is fixed on the fixed main shaft 400, a part of the stirring shovel is fixedly provided with a transmission shaft 405 that extends into the transmission box 401 and is fixed to the transmission gear 404, the transmission shaft 405 is rotatably connected to the transmission box 401, and another part of the stirring shovel is fixedly connected to the transmission box 401, and a driving member is arranged on the transmission box 401 for transmission.

[0042] Specifically, there are two transmission gears 404, which are symmetrically arranged in the transmission box 401, and a transmission shaft 405 is fixedly arranged on each transmission gear 404. The two transmission gears 404 are symmetrically arranged and distributed in a mirror image around the fixed gear 403, which helps to maintain the balance and stability of the entire transmission system during operation.

[0043] Further preferably, each transmission shaft 405 is provided with a connecting portion 407, on which two mixing shovels 100 are provided, and the shovel surfaces 301 of the two mixing shovels 100 are in opposite directions, and two mixing shovels 100 are also fixedly provided on the transmission box 401, and the shovel surfaces 301 of the two mixing shovels 100 are also in opposite directions.

[0044] It is worth mentioning that the connecting portion 407 includes a connecting plate, both ends of which are tilted upward, and the stirring shovel 100 is respectively fixed to the two ends of the corresponding connecting plate.

[0045] In this embodiment, each connecting portion 407 is equipped with two stirring spatulas 100 with shovel surfaces 301 in opposite directions, which means that when the stirring spatulas 100 rotate clockwise, the stirring directions of the two stirring spatulas 100 are the same, and multi-level food turning can be achieved during the cooking process, thereby enhancing the mixing effect, reducing dead corners, and ensuring that the food is heated more evenly.

[0046] Specifically, the fixed main shaft 400 is fixed to the support frame, and a driving bevel gear 402 is fixedly arranged on the transmission box 401. The driving member meshes with the driving bevel gear 402 to realize power transmission, and the fixed main shaft 400 passes through the transmission box 401 and is fixedly connected to a fixed gear 403 in the transmission box 401. Two transmission gears 404 are symmetrically arranged in the transmission box 401. The two transmission gears 404 are respectively meshed with the fixed gear 403, and each transmission gear 404 is fixedly connected to a transmission shaft 405. Each transmission shaft Two mixing shovels 100 are fixedly arranged on 405 through the connecting part 407, the transmission shaft 405 is fixed to the connecting shaft 105, and two mixing shovels 100 are directly fixed to the transmission box 401. Then, as the transmission box 401 rotates, all the mixing shovels 100 can rotate around the fixed main shaft 400. At the same time, the two transmission gears 404 rotate around the fixed gear 403, so that the mixing shovels 100 on the transmission shaft 405 rotate around the fixed main shaft 400, and the transmission shaft 405 also rotates with the mixing shovels 100.

[0047] Further preferably, the transmission shaft 405 is gradually inclined outward while extending downward.

[0048] In this embodiment, the drive shaft 405 gradually tilts outward as it extends downward, which means that they are not installed perpendicular to the bottom of the pot, but extend outward at a certain angle. This inclined design can make the stirring shovel 100 closer to the pot wall, especially in a pot with a round bottom or an arc bottom, which helps to reduce cooking dead corners and ensure that the ingredients can be fully turned over.

[0049] Further preferably, a temperature control tube 406 is provided on the fixed main shaft 400 to monitor the temperature in the wok.

[0050] Further preferably, the transmission shaft 405 is gradually tilted outward while extending downward, so that the stirring and frying is tilted to achieve stirring or stir-frying on the edge of the pot.
