In daily life, the expansion screw we use is very convenient to install,but it is very difficult to disassemble generally. In many cases, workers choose to cut it directly or not to disassemble it at all. Faced with this situation, the workers are also very helpless.In view of this situation, we designed this expansion screw which is more convenient to disassemble and assemble, aiming at solving this difficult phenomenon.In addition, designers hope to reuse it many times, which can not only solve the difficult disassembly problems, but also save resources.
In the installation process, the expansion screw is first put into the pre-punched hole, and the middle part will be tightened and expanded when tightened,thus playing a tightening role. When disassembly, only a few downward hammers are needed to flatten the tightened shape and smoothly remove the original expansion screw. The detachable expansion screw has two functions: stretching and tightening. It can make workers more comfortable in the process of disassembly and assembly, thereby improving work efficiency and reducing waste of resources.
