[0002] A return handle is a handle with an automatic reset function and is widely used on doors, drawers, and other furniture. When the user releases the handle, it automatically returns to its original position, securing the door or drawer closed. The design of this type of handle typically includes a handle, a spring mechanism, and mounting components. The handle, typically made of metal or plastic, provides the part that people grasp and pull. The spring is the core component that achieves the automatic reset function. It is housed inside the handle and uses its elasticity to keep the handle in its original position. When people pull hard to open a door or drawer, the spring is stretched, but once released, it quickly returns to its original state, pulling the handle back to its original position. The mounting components are used to secure the handle to the door or drawer. These components can be screws, nuts, washers, or other types of fixings.
[0003] In the prior art, the return function handle is mostly installed on the extended side of the door or extends from the inside of the door, which cannot be flush with the door surface, is not easy to clean the door surface, and may cause the handle to collide with the door surface and damage the door surface. Utility Model Content

[0006] As a further description of the above technical solution:
[0007] The connecting mechanism includes two torsion spring fixing screws, and the two torsion spring fixing screws are respectively threadedly connected to the upper and lower ends of the handle front cover body.
[0008] As a further description of the above technical solution:
[0009] The mounting mechanism includes two rear cover fixing screws, which are respectively threadedly connected to the upper and lower ends of the handle rear cover body.
[0010] As a further description of the above technical solution:
[0011] A handle is provided between the handle front cover body and the handle rear cover body. A return mechanism is provided inside the handle, and the return mechanism is used to rotate and reset the handle.
[0012] As a further description of the above technical solution:
[0013] The return mechanism includes two shaft sleeves, which are rotatably connected to the upper and lower ends of the handle respectively, and the outsides of the two shaft sleeves are both sleeved with special-shaped torsion springs.
[0014] As a further description of the above technical solution:
[0015] One end of the special-shaped torsion spring is fixedly connected to the inside of the handle, and the other end of the special-shaped torsion spring is fixedly connected to the outside of the shaft sleeve.
[0016] As a further description of the above technical solution:
[0017] The exterior of the handle is arc-shaped and is provided with anti-slip grooves.
[0018] As a further description of the above technical solution:
[0019] The handle front cover body and the handle rear cover body are fixedly connected to the inner and outer sides of the glass door surface respectively.
[0020] The utility model has the following beneficial effects:
[0021] 1. In this utility model, a torsion spring allows the center handle to be actively moved inward and outward, returning precisely to its original position. A flush handle is secured with internal screws, ensuring a flush fit between the handle and the glass door surface, making it easy to clean. Furthermore, the flush handle avoids the risk of traditional handles colliding with fixed doors, thereby increasing door opening space and creating a clever and aesthetically pleasing overall structure.
