[0020] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following description of the specific embodiment of the present utility model will be described in detail in conjunction with the accompanying drawings of the specification.

[0021] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model may be implemented in other ways other than those described herein, and those skilled in the art may similarly promote the present utility model without violating the spirit of the present utility model, and therefore the present utility model is not limited to the specific embodiments disclosed herein.

[0022] Second, the term "an embodiment" or "embodiments" referred to herein refers to specific features, structures, or characteristics that may be included in at least one embodiment of the utility model. The phrase "in one embodiment" in various places throughout this specification does not always refer to the same embodiment, nor is it a separate or selective embodiment that excludes other embodiments. Embodiment 1

[0023] With reference to the Fig. 1 to 2, a first embodiment of the utility model is shown which provides a spiral telescopic structure, the spiral telescopic structure comprising a main body assembly 100 having an outer shell 101 and an inner housing 102 and a telescopic assembly 200 having a drive element 201, a rotary element 202, a telescopic element 203 and a limiting element 204.

[0024] In particular, the inner shell 102 is provided inside the outer shell 101, the drive element 201 is provided outside the outer shell 101 and comprises a drive motor 201a and a drive rod 201b, the drive motor 201a is provided outside the outer shell 101 and is fixedly connected to the outer shell 101 via a fixed bearing seat 101a, and the drive rod 201b is driven by the drive motor 201a.

[0025] Specifically, the rotating member 202 is fixedly connected to the driving member 201 and includes a connecting arm 202a, a limiting block 202b, a rotating rod 202c, and a blocking arm 202d. The connecting arm 202a is fixedly connected to the driving rod 201b so that it can rotate with the driving rod 201b driven by the driving motor 201a. Also, because the rotating rod 202c is fixedly connected to the connecting arm 202a, the rotating rod 202c will move in a circular motion around the driving rod 201b with the connecting arm 202a as its radius. The limiting block 202b is provided on the rotating rod 202c and is limited by the limiting member 204 while rotating with the rotating rod 202c.The rotary member 202 also includes a follower gear 202e and an internal gear 202f, the follower gear 202e is movably connected to the rotary rod 202c, the internal gear 202f is fixedly connected to the inner shell 102, and the internal gear 202f is always prevented from being immobile and can mesh with the follower gear 202e.

[0026] Furthermore, the telescopic element 203 is arranged within the inner shell 102 and includes a fastening element 203a, a threaded rod 203b, and a column gear 203c, wherein the fastening element 203a is arranged between the connecting arm 202a and the blocking arm 202d. The fastening element 203a is rotatably connected to the connecting arm 202a so that it does not rotate with the fastening element 203a when the connecting arm 202a is rotated. The threaded rod 203b is screwed to the fastening element 203a, and the column gear 203c is fixedly connected to the threaded rod 203b and meshes with the follower gear 202e.

[0027] In operation, starting the drive motor 201a drives the drive rod 201b, causing the connecting arm 202a to rotate, thereby moving the rotating rod 202c circumferentially around the drive rod 201b with the connecting arm 202a as the radius. At this time, the follower gear 202e, which is movably connected to the rotating rod 202c, simultaneously meshes with the internal gear 202f and the column gear 203c. The follower gear 202e, as it rotates with the rotating rod 202c, drives the column gear 203c to rotate, thereby driving the threaded rod 203b, which is fixedly connected to the column gear 203c, to rotate.And because at this time, the fastener 203a is blocked by the blocking arm 202d, the threaded rod 203b gradually extends from the fastener 203a and drives the column gear 203c to gradually expand, and it should be noted that the thickness of the column gear 203c is larger than that of the follower gear 202e and the internal gear 202f, so that it will not be disengaged from the meshing during the pulling-in process, and thus the pulling-in effect can be completed.

[0028] In summary, the present solution can complete the telescopic function of the stirrer through the drive element 201, the rotary element 202 and the telescopic element 203, thereby avoiding the problem that the height of the impeller of the existing stirrer cannot be adjusted, cannot adapt to the stirring conditions under different liquid level changes and reduces the efficiency of stirring the liquid. Embodiment 2

[0029] With reference to the Fig. 1 to 3, a second embodiment of the utility model is shown, which provides a spirally retractable structure and differs from the previous embodiment in that the embodiment provides a spirally retractable structure comprising a limiting element 204 arranged within the outer shell 101.

[0030] Specifically, the limiting member 204 includes a rotary ring 204a, a shift groove 204b, a shift block 204c, and a track slot 204d, and the rotary ring 204a is provided on the outer shell 101. The shift groove 204b is open in the outer shell 101, the shift block 204c is fitted onto the rotary ring 204a, and the shift groove 204b and the shift block 204c are sized to allow the shift block 204c to rotate in the shift groove 204b. The track slot 204d is provided on the rotary ring 204a to allow the free rotation of the limiting block 204b and to ensure that the movement of the limiting block 204b is not affected when the rotary ring 204a is rotated.

[0031] In use, after the telescopic function is completed, the switching block 204c on the rotary ring 204a is moved from bottom to top by rotating the rotary ring 204a and remains at the top. At this time, the rotary ring 204a drives the limit block 202b to raise it, which in turn causes the rotary rod 202c and the follower gear 202e to rise. At this time, the follower gear 202e is disengaged from the meshing state with the internal gear 202f. Since the follower gear 202e is movably connected to the rotary rod 202c, the follower gear 202e no longer supports the column gear 203c to rotate when it moves in a circular motion, and instead, the follower gear 202e itself is driven and rotates around the column gear 203c. The column gear 203c no longer rotates, so that the telescopic function stops, and conversely, it can then telescope.

[0032] Preferably, the rotating ring 204a is provided with an actuating lever 204a-1 in order to save more effort when lifting the rotating ring 204a.

[0033] In summary, the present system enables the expansion structure to stop in time after the expansion function is completed through the role of the limiting element 204, which is simple and effective, so that the agitator can adapt to the mixing conditions of various liquid level changes and make the mixing more efficient. Embodiment 3

[0034] With reference to the Fig. 1 to 5, a third embodiment of the utility model is shown, and the embodiment provides an agitator, the agitator comprising the helical telescopic structure of Embodiments 1 and 2 and further comprising a stirring device 300 having a stirring blade 301, a stirring rod 302 and a follower rod 303.

[0035] Specifically, the stirring rod 302 is movably connected to the telescopic member 203, the follower rod 303 is movably connected to the telescopic groove 202e-1 fixedly connected to the rotating member 202, and the stirring blade 301 is fixedly connected to the stirring rod 302.

[0036] During the telescopic function, the stirring rod 302 is driven by the follower rod 303 to rotate at the lower end of the column gear 203c of the telescopic member 203, and does not drive the column gear 203c to rotate, which does not affect the telescopic function. Furthermore, at the end of the telescopic function, the follower gear 202e is self-driven and rotates around the column gear 203c, and the stirring rod 302 can still be driven by the follower rod 303 to rotate, thus rotating the stirring blade 301.Also, because the follower rod 303 is movably connected to the telescopic groove 202e-1 fixedly connected to the rotating member 202, the follower rod 303 is not invalidated by the action of the telescopic member 203, resulting in a failure of the connection effect, and it can always be kept at the same height as the telescopic member 203 and drive the stirring rod 302 to rotate and complete the stirring function.

[0037] In summary, the present embodiment operates by means of the stirring device 300, which does not affect the telescoping function during the stirring operation and enables normal stirring in the middle of the telescoping and in the mouth after the telescoping is completed, so that the stirring and telescoping functions are effectively combined and the height of the stirrer can be regulated according to the real-time situation.

[0038] In order to describe the exemplary embodiment briefly and concisely, it is possible to omit all features of the actual embodiment (ie those features that are not relevant to the currently considered optimal embodiment of the present utility model or those features that are not relevant to the realization of the present utility model).

[0039] It should be understood that when developing a practical application, such as an engineering or design project, a large number of implementation-specific decisions may be made. Such a development effort can be complex and time-consuming, but for those skilled in the art, having access to this disclosure, this development effort becomes a routine exercise in design, manufacturing, and production without significant experimentation.

[0040] It should be noted that the above embodiments serve only to illustrate the technical solutions of the present utility model and should not be considered limiting. Despite the detailed description of the present utility model with reference to the preferred embodiments, it should be obvious to those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present utility model without departing from the spirit and scope of the technical solutions of the present utility model, which are covered by the scope of the claims of the present utility model.
