[0002] At present, with the increase of family income and the improvement of cultural level, people have higher and higher requirements for furniture environment. However, the handles used on traditional furniture doors or home appliance doors mostly only have structural conditions for gripping and stretching, and their decorative function is very weak. Some handles may even corrode due to long-term exposure, which further reduces the aesthetics and is not welcomed by consumers.

[0003] In recent years, with the further development of relevant technologies, some technical solutions for invisible handles have also appeared in the prior art. For example, the patent document with application number 202211119614.2 proposes "an invisible door handle on a refrigerator door, the invisible door handle comprising a flat plate portion and a columnar handle portion constituting an annular body, touch switches are respectively provided on the flat plate portion and the columnar handle portion, and installation mating ends connected to the refrigerator door are respectively provided at the connecting parts of the flat plate portion and the columnar handle portion, and a rotating shaft mounting hole and an output shaft mounting hole of the handle drive motor are respectively provided at the installation mating ends". After use, "the invisible door handle for the refrigerator door has beautiful appearance, simple structure, convenient operation, easy processing and manufacturing, and easy automatic cleaning of the door handle".

[0004] From the public content of the above-mentioned prior art, it can be seen that the technical effect of the handle being protruding when in use and hidden when idle is achieved. However, from the analysis of the specific structure, the operation of the above-mentioned prior art is based on the output of motor power. In other words, in the case of power outages in real life, the convenience of using the handle provided by the above-mentioned prior art will be greatly reduced. Secondly, the noise and electricity costs generated during the operation of the motor, and the occurrence of these adverse effects can only be exchanged for the hiding and protruding use of the handle, the difference between the benefits and costs is large, and the practicality is limited.

[0009] Preferably, the diameter of the top of the first gasket is greater than the diameter of the top of the inverted T-shaped groove, thereby avoiding the phenomenon of structural separation. The surface of the middle part of the first gasket is provided with a first O-ring that fits and connects to the inner wall of the bottom of the inverted T-shaped groove, thereby reducing the noise problem during the movement of the structure.

[0010] Preferably, the locking assembly includes a nut and a second gasket, and the nut and the second gasket are respectively clamped and threadedly connected to the end surface of the screw away from the base, thereby providing convenient conditions for installing the entire device on a specified structure.
