Description

TECHNICAL FIELD

[0001] The utility model belongs to hardware parts technical field, concretely relates to a variable-diameter hoop. BACKGROUND

[0002] In the production and assembly process of electronic equipment, the fixation of small electronic components is a key task. These components usually have light weight and small size, and require reliable fixation methods to ensure their stability during operation. As an effective fixing device, the variable-diameter hoop has been widely used in the field of electronic equipment. The installation process of the variable-diameter hoop is relatively simple and does not require complex tools and techniques. It can be quickly installed on the bracket and adjusted as needed. This is very important for the production and assembly process of electronic equipment, which can improve production efficiency. The design of the hoop can provide sufficient friction to ensure that the components do not loosen during operation. The variable-diameter hoop can closely fit the surface of the component to prevent displacement of the component when it is subjected to vibration or external force.

[0003] One disadvantage of a variable-diameter hoop is that it is difficult to adjust on site if the size of the hoop is found to be inappropriate during installation. In the maintenance process of electronic equipment, if the size of the hoop is found to be inappropriate, it will cause great trouble to the maintenance work because it cannot be adjusted on site. When a damaged electronic component needs to be replaced, and the size of the original fixing hoop does not match, it may not be possible to directly use the existing hoop for fixation. When the hoop has a large contact area with the object, the pressure exerted by the hoop during fixation is distributed over a large area, resulting in a large friction force. This repeated pressure action may cause the material on the surface of the object to gradually fatigue and peel off, thereby exacerbating wear and tear. SUMMARY
