The rotating base is provided with a push Screw rod, the push screw rod is arranged at the center of the rotating base, and the screw rod is fixed with the base buckle through the arc expansion strip. However, after this spinner bottle is used up, it cannot be reused, causing environmental pollution.

There are also some containers that can be replaced. The shell and the replaceable core are provided with mutually matching pressing elastic buckles and buckle grooves. Then the replacement core can be pulled out from the casing, but the elastic buckle of this container is particularly easy to derail from the buckle groove or lose its elasticity due to material aging and other reasons, which causes inconvenience to use. Secondly, the process of installing and assembling the container of this structure is relatively cumbersome. There are also replaceable cores in some replaceable containers that are directly placed on the liftable floor, but as the internal paste gradually decreases during use, the weight of the replaceable cores is also getting smaller and smaller. Misalignment is also prone to occur.

As shown in Fig. 29 to Fig. 31 and Fig. 33, the bottom of the bottom plate 430' is provided with a fourth fastener 431', and the top of the threaded pipe is provided with a fifth fastener 610' corresponding to the fourth fastener 431', The fifth fastener extends upwards (along the axial direction of the threaded pipe toward the direction away from the threaded pipe) and outwards (along the radial direction away from the central axis of the threaded pipe) from the top of the threaded pipe, That is to say, in the axial direction of the threaded pipe jacking, the fifth fastener is higher than the threaded pipe jacking, so a second gap 620' is formed between adjacent fifth fasteners, and there is a gap 620' between the threaded pipe jacking. In the radial direction, the fifth fastener is wider than the threaded pipe jacking. From Figure 30, the diameter of the inner wall of the fifth fastener is slightly smaller than the diameter of the inner wall of the threaded pipe jacking. In other embodiments, the fifth fastener The diameter of the inner wall can be equal to or greater than the diameter of the inner wall of the threaded jacking pipe, and the fastening or separation of the fourth fastener and the fifth fastener can be realized by the relative rotation of the replacement component and the threaded jacking pipe.

Both the second notch and the fifth fastener are two, the two second notches are oppositely arranged, and the two fifth fasteners are also arranged oppositely, the extension part of the fourth fastener 431' extends into the second notch and rotates along the guide rail , the fourth fastener 431' is engaged with the fifth fastener. Also be provided with screw thread 640 ' on the inner wall of the lower end of screw jack pipe, be used for being threadedly connected with screw rod.

The guide in this embodiment is a guide bar 630' attached to the outer wall of the columnar threaded pipe jacking, the guide bar is arranged along the axial direction of the threaded pipe jacking, and the guide bar starts to extend from the lower end of the threaded pipe jacking And extend to the upper end of the threaded jacking pipe. Moreover, the bottom of the cylindrical groove of the support extends to both sides of the cylindrical limiting column 540', and the limiting column is provided with a guide rail 541' that matches the guide bar of the threaded pipe jacking. The guide bar 630' moves along the guide rail 541'.

As shown in Figure 31 to Figure 34, one end of the guide rail (near the lower end of the threaded jacking pipe) is provided with a step 631, and at the same time, the top part of the limit post 540' extends upwards and is provided with two inverted claws 560, the inverted claws 560 and The steps 631 cooperate with each other to have a limited lease. In the later stage of use, when the top and bottom plates on the threaded jacking pipe drive the replacement assembly upwards, the threaded jacking pipe has gone up to the end of the stroke, and at this time the two claws on the support will contact the two steps on the threaded jacking pipe, Thereby stop thread jacking pipe from continuing upward and falling off from support.

Different from the first embodiment where the guide rails are arranged in the direction of the semi-minor axis of the elliptical bottom plate, in this embodiment the guide rails are arranged in the direction of the semi-major axis of the elliptical bottom plate. In this embodiment, the first fastener 451' and the fourth fastener 431' are on the same straight line. Similarly, the first notch 550', the second notch 620', and the guide rail 541' are also on the same straight line, and The arrangement direction of the two first fasteners is perpendicular to the arrangement direction of the two first notches 550', that is to say, as long as it is rotated 90 degrees, the replacement component and the support are fastened or separated, and the replacement component is also connected to the threaded top at the same time. Tubes snap together or separate.

Those skilled in the art should understand that, in the disclosure of the present utility model, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal" , "top", "bottom", "inner", "outer" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than The above terms should not be construed as limitations on the invention if it indicates or implies that the device or element referred to must have a certain orientation, be constructed and operate in a certain orientation.
