Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figure 1-7 As shown, this utility model provides a retractable blade stirring paddle, including a stirring rod 100. A connector 200 is fixedly provided at the bottom end of the stirring rod 100. Two receiving grooves 300 are provided at the bottom of the connector 200, which are arranged in a circular array along the circumference of the connector 200. A shaft pin 400 is rotatably provided in both receiving grooves 300. A stirring blade 500 is fixedly sleeved on both shaft pins 400. A telescopic blade 600 with adjustable position is provided at the end of the stirring blade 500. The telescopic blade 600 slides in the stirring blade 500.

[0028] An adjustment component 700 is provided between the stirring rod 100 and the connector 200. The adjustment component 700 synchronously drives the two shaft pins 400 to rotate, thereby realizing the folding and unfolding of the stirring rod 100.

[0029] In this embodiment, the end of the stirring blade 500 is provided with a square groove 501, the end of the telescopic blade 600 is inserted into the square groove 501, and the telescopic blade 600 can move along the length direction of the square slot 502.

[0030] In this embodiment, the telescopic blade 600 has symmetrically distributed receiving cavities 601. A compression spring 602 is fixedly connected to the receiving cavity 601. One end of the compression spring 602 is fixedly connected to a plug 603. The stirring blade 500 has several slots 502 that communicate with the directional sliding groove and match the plug 603. The end of the plug 603 away from the compression spring 602 passes through the telescopic blade 600 and is inserted into the slot 502, so that the plug 603 leaves the slot 502 and squeezes the compression spring 602. When the plug 603 leaves the slot 502, it can pull the telescopic blade 600 to move along the length direction of the square slot 502 until it moves to the position of the next row of slots 502. The elastic force of the compression spring 602 pushes the plug 603 to be inserted into the corresponding slot 502 again, thereby fixing the telescopic blade 600 and realizing the adjustment of the telescopic blade 600.

[0031] In this embodiment, the slot 502 is a countersunk hole with a diameter that gradually decreases from the stirring blade 500 to the telescopic blade 600. The minimum diameter of the slot 502 is the same as the diameter of the plug 603, which makes it convenient for fingers to be inserted into the slot 502 to press the plug 603.

[0032] In this embodiment, the adjustment component 700 includes a rotating shaft 701 rotatably disposed between the connector 200 and the stirring rod 100. A driving bevel gear 702 is fixedly sleeved on the outer wall of the rotating shaft 701. Two pins 400 are respectively fixedly connected to opposite ends of a driven bevel gear 703 that meshes with the driving bevel gear 702. The driving bevel gear 702 can drive the driven bevel gear 703 to rotate, and the driven bevel gear 703 drives the pins 400 to rotate the stirring blade 500. The stirring blade 500 can rotate from 0° to 90°.

[0033] In this embodiment, a worm gear 704 located inside the stirring rod is fixedly sleeved on the outer wall of the rotating shaft 701. A worm 705 that meshes with the worm gear 704 is rotatably provided on the stirring rod. The worm gear 704 is driven to rotate by controlling the rotation of the worm 705. The worm gear 704 drives the rotating shaft 701 to rotate the active bevel gear 702. The worm gear 704 and the worm 705 have a self-locking ability, which can prevent the rotating shaft 701 from being accidentally touched during stirring.

[0034] In this embodiment, the end of the worm 705 extends to the outside of the stirring rod, and the end of the worm 705 is provided with an internal hexagonal hole 706, which facilitates the rotation of the worm 705.

[0035] How to use and how to work this device:

[0036] When using this device, first, depending on the size of the container, insert your finger into the slot 502 and press the plug 603 to make the plug 603 leave the slot 502 and squeeze the compression spring 602. After the plug 603 leaves the slot 502, you can pull the telescopic blade 600 to move along the length of the square slot 502 until it moves to the position of the next row of slots 502. The elastic force of the compression spring 602 pushes the plug 603 to be inserted back into the corresponding slot 502 to fix the telescopic blade 600. This allows the telescopic blade 600 to be adjusted so that its length is suitable for the size of the container, achieving the best stirring effect.

[0037] For containers with narrow openings, the stirring blades 500 and telescopic blades 600 face downwards to facilitate entry into the narrow-mouthed container. After the telescopic blades 600 enter the container, the worm gear 704 is driven to rotate by controlling the rotation of the worm 705. The worm gear 704 drives the rotating shaft 701 to rotate the driving bevel gear 702, which in turn drives the driven bevel gear 703, which meshes with the driving bevel gear 702, to rotate. The driven bevel gear 703 drives the shaft pin 400 to rotate the stirring blades 500. The stirring blades 500 can rotate 90° to be perpendicular to the stirring rod, allowing the stirring blades 500 to unfold inside the bottle, facilitating stirring in this type of bottle.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
