The sleeve 12 is clamped on the connecting tube 15. When the sleeve 12 squeezes the connecting tube 15, the sleeve 12 pushes the connecting tube 15 to retract in the second accommodating chamber 1112. The mounting seat 11 is used to be mounted on the food blender. The crushing device 14 is located in the sleeve 12. The crushing device 14 is used to crush the food. The sleeve 12 is used to hide the crushing device 14 to prevent the crushing device 14 from causing safety hazards in the process of crushing food. The sleeve 12 is retractably connected to the second accommodating chamber 1112 of the mounting seat 11, the reset member 13 is used to reset the sleeve 12, the connecting tube 15 is used to limit the reset member 13 and fix the sleeve 12, and the outer cover 112 is used to wrap the second accommodating chamber 1112. When the stirring mechanism stirs the food, when the food is piled up too high and the crushing device 14 cannot crush the food, the squeezing stirring mechanism squeezes the sleeve 12 to squeeze the food, and the other end of the sleeve 12 squeezes the connecting tube 15, and the connecting tube 15 pushes the reset member 13 and the reset member 13 is deformed, and the sleeve 12 pushes the connecting tube 15 to move toward the second accommodating chamber 1112, and one end of the sleeve 12 extends into the second accommodating chamber 1112. When the sleeve 12 is extended and retracted into the second accommodating chamber 1112, the crushing device 14 is gradually exposed to the outside of the sleeve 12, thereby facilitating the crushing of food. Since the sleeve 12 is extended and retracted in the second accommodating chamber 1112, and the outer cover 112 wraps the inner lining 111, the sleeve 12 will not clamp the clothes when it is extended and retracted or fits with the second accommodating chamber 1112, thereby eliminating hidden safety hazards.

[0034] Please refer to Figure 6 , Figure 6It is a stereoscopic diagram of the connecting tube of the retractable stirring mechanism of the utility model, the second accommodating chamber 1112 includes a movable chamber and a limiting chamber, the diameter of the limiting chamber is smaller than the diameter of the movable chamber, the connecting tube 15 includes a first fixed tube 151 located in the movable chamber and a second fixed tube 152 connected to the limiting chamber, the diameter of the first fixed tube 151 is larger than the diameter of the second fixed tube 152, the reset member 13 is located in the first fixed tube 151, the movable chamber is used to place the first fixed tube 151, so that the first fixed tube 151 can be retracted in the movable chamber, the second fixed tube 152 is connected in the limiting chamber, the side wall of the limiting chamber is used to limit the first fixed tube 151 to prevent the first fixed tube 151 from separating from the movable chamber, and at the same time, the second fixed tube 152 is used to limit the sleeve 12 to prevent the sleeve 12 from shaking in the connecting tube 15.

[0035] Please refer to Figure 7 , Figure 7 It is a three-dimensional diagram of the sleeve of the retractable stirring mechanism of the utility model. A plurality of arc-shaped openings 154 and a limiting protrusion 153 located between adjacent arc-shaped openings 154 are provided at the connection between the second fixed tube 152 and the first fixed tube 151 for limiting the reset member 13. A connecting plate 124 extending into the arc-shaped opening 154 and clamped on the second fixed tube 152 is provided at one end of the sleeve 12. The reset member 13 is sleeved on the outer side of the limiting protrusion 153. The limiting protrusion 153 and the side wall of the first fixed tube 151 position the reset member 13 to prevent the reset member 13 from being positionally shifted in the first fixed tube 151. The arc-shaped opening 154 is used to facilitate the insertion of the connecting plate 124 of the sleeve 12. After being inserted, the connecting plate 124 is bent and fixed to the second fixed tube 152, thereby facilitating the sleeve 12 to push the connecting tube 15 to move.

[0036] In the present invention, the reset member 13 is a compression spring, but is not limited to using only a compression spring.

[0037] The crushing device 14 includes a knife shaft 141 and a cutter 142 connected to one end of the knife shaft 141. The cutter 142 is located on the outside of the sleeve 12. The other end of the knife shaft 141 passes through the second accommodating cavity 1112 and extends into the first accommodating cavity 1111. One end of the knife shaft 141 is fixed in the first accommodating cavity 1111 and fixed by a nut. The knife shaft 141 is used to extend the distance of the cutter 142, so as to facilitate the cutter 142 to be inserted into the container to crush the food.

[0038] The bottom wall of the first accommodating chamber 1111 is provided with a placement groove protruding toward the second accommodating chamber 1112, and a first oil seal bearing 1113 is provided in the placement groove. The knife shaft 141 is located in the first oil seal bearing 1113. The placement groove is used to place the first oil seal bearing 1113. The first oil seal bearing 1113 is used to prevent the lubricating oil in the first accommodating chamber 1111 from flowing into the second accommodating chamber 1112. At the same time, the first oil seal bearing 1113 can also limit the knife shaft 141 to prevent the knife shaft 141 from shaking.

[0039] The side wall of the placement groove forms a bulge 1114 in the second accommodating cavity 1112, and the reset member 13 is sleeved on the outer side of the bulge 1114. The bulge 1114 is used to limit the reset member 13. The two ends of the reset member 13 are limited by the bulge 1114 and the connecting tube 15, thereby preventing the reset member 13 from positionally shifting in the second accommodating cavity 1112, so that the reset member 13 can stably reset the connecting tube 15.

[0040] Please refer to Figure 3 and Figure 5 , Figure 3 for Figure 2 The sectional view along the cutting line AA is shown in the figure. Figure 5 for Figure 3 In the partial enlarged view of part B, a second oil seal bearing 122 sleeved on the knife shaft 141 is further provided at one end of the sleeve 12 close to the cutter 142, and a sealing ring 123 sleeved on the circumferential side of the second oil seal bearing 122 is further provided in the sleeve 12. The sealing ring 123 is used to seal between the second oil seal bearing 122 and the sleeve 12, and the second oil seal bearing 122 is used to limit the knife shaft 141. Both ends of the knife shaft 141 are limited by the first oil seal bearing 1113 and the second oil seal bearing 122 at the same time, so that the knife shaft 141 always keeps the same position for rotation, and the knife shaft 141 can stably drive the cutter 142 to crush the food when rotating.

[0041] A food splash prevention shield 121 is also provided at one end of the sleeve 12 near the cutter 142. The cutter 142 is located in the shield 121. The shield 121 is used to prevent the crushed food from splashing. The splashed food can fall back into the container and the rotating cutter 142 after rebounding from the shield 121. When the food falls back into the rotating cutter 142, it can be crushed again, thereby increasing the efficiency of crushing the food.

[0042] A baffle 1211 is also provided between the shield 121 and the sleeve 12, and the baffle 1211 is used to prevent food from entering the pipeline, thereby reducing the difficulty of cleaning the stirring mechanism.

[0043] Working principle:

[0044] When it is necessary to mix the food, first, the mounting base 11 is connected to the mixer, the driving source on the mixer is connected to the blade shaft 141, the mixer is started, the mixer drives the blade shaft 141 to rotate, and the blade shaft 141 drives the cutter 142 to rotate, so as to mix the food. When the started mixing mechanism is extended into the container to grind the food, when there are a lot of food to block the shield 121, the mixing mechanism is squeezed downward. Since the shield 121 is connected to the sleeve 12, when the shield 121 is squeezed, the sleeve 12 retracts in the second accommodating chamber 1112, the connecting plate 124 of the sleeve 12 is fixed on the second fixed tube 152, and when the sleeve 12 retracts, the sleeve 12 pushes the connecting tube 15 to move, and the reset member 13 is squeezed by the connecting tube 15 in the second accommodating chamber 1112 is deformed, so that the sleeve 12 retracts in the second accommodating chamber 1112. Furthermore, during the retraction of the sleeve 12, the cutter 142 extends to the outside of the protective cover 121, so that the cutter 142 contacts the food to stir the food. When the stirring mechanism loses the extrusion force, the reset member 13 recovers the deformation and reversely squeezes the connecting tube 15. The connecting tube 15 drives the sleeve 12 to move, so that the cutter 142 is re-positioned in the protective cover 121. When the stirring mechanism is not in use, the exposed cutter 142 is prevented from causing safety hazards. At the same time, because the sleeve 12 is connected to the second accommodating chamber 1112, the sleeve 12 is not exposed to the outside when it is extended and retracted in the second accommodating chamber 1112, which can effectively avoid clamping of clothes, etc., eliminate potential safety hazards, and make it safer when processing food.

[0045] When the retractable stirring mechanism of the preferred embodiment squeezes the food through the stirring mechanism, when the squeezing force is greater than the elastic force of the reset member, the sleeve pushes the connecting tube to move, and the connecting tube pushes the reset member to move. The reset member is deformed by the force, so that the sleeve retracts in the second accommodating chamber. When the sleeve retracts, it is convenient for the crushing device to crush the food. The sleeve retracts in the second accommodating chamber and will not clamp the clothes when it is extended or retracted, thereby eliminating potential safety hazards and making food processing safer.

[0046] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
