thereby the vertical recess of the draw-in groove 5a on the top cap 1 of drive slides along fixed cylinder 4a, until the horizontal recess of the draw-in groove 5a of top cap 1 rotates to the position of coinciding with fixed cylinder 4a of top cap 1 mutually, the horizontal recess of the draw-in groove 5b of top cap 1 rotates to the position of coinciding with fixed cylinder 4b of top cap 1 mutually.

At the moment, the upper end surface of the top cap 1 slides downwards until being flush with the upper end surface of the bottom cylinder 2.

The operation process of the specific details of the process is different from that of the embodiment 1 in that: at this time, the clamping groove 5 is of a T-shaped groove structure, so that when the top cap 1 is screwed by feet (or hands) continuously, the top cap can be screwed clockwise or anticlockwise, the top cap 1 can be limited and clamped and hidden in the bottom cylinder 2, and even if the door stopper is hidden on the ground (or the floor surface or the decorative ground) and is level or below the ground.

Example 5

This example differs from example 1 in that:

optimized, the pre-buried door of the formula of preventing changeing is inhaled, stop device is the helicitic texture, and helicitic texture one includes a pair of internal thread and the external screw thread of locking each other, and the external screw thread setting is on the lateral wall of hood 1, and the internal thread setting is on the inside wall of end jar 2.

In the specific use process, the external thread of the top cap 1 and the internal thread of the bottom cylinder 2 are relatively displaced by rotating the top cap 1, so that the up-down relative displacement position relation between the top cap 1 and the bottom cylinder 2 is adjusted, and the height of the top cap 1 extending out of the end surface of the bottom cylinder 2 is controlled.

The height of the top cap 1 of the door stopper is controlled through the process; when the door stopper is used, the top cap 1 is enabled to protrude out of the upper end surface of the bottom cylinder 2 through rotation; when the door stopper is not used, the top cap 1 is hidden in the bottom cylinder 2 by rotation.

It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should understand that they can make various changes, modifications, additions and substitutions within the spirit and scope of the present invention.
