It should be said that the expansion tube existed before the expansion screw. It evolved from the base of the cork to the plastic expansion plug. After the test of time and environment, the performance of the Huanjie expansion tube is far better than that of the cork. The first thing is to reduce it. The magnitude of small cold shrinkage and thermal expansion is also superior to wood materials in terms of anti-aging effect, and it has good stress, and is convenient and standard in matching size. It can exert the maximum fastening force for a long time in special environments such as insulation and water (humid) requirements. Thus won the pursuit of the majority of users. First, use an electric impact drill to make a hole in the wall. The diameter of the hole should be as large as the outer diameter of the expansion tube. After the hole is drilled, clean up the residue left by the drilling (cleaning can be done with wind or water. Use a wool sweep, etc.) to avoid sliding of the expansion tube due to dust to increase friction. Then use a hammer to drive the expansion tube into the hole, and finally drive the expansion nail into the hole.

It should be noted that the hole pitch cannot be greater than the expansion tube, which will cause the expansion tube to loosen easily. What to pay attention to when installing the expansion pipe 1. Be careful not to punch holes in the same place multiple times, so that the hole position is easy to expand, resulting in the expansion pipe not being strong. 2. Avoid repeated use of the same expansion tube, which will cause the expansion tube to break, deform, easily cause screw deviation, and poor tightening force. 3. The depth of the required hole should be about 5 mm greater than that of the expansion pipe, so that the expansion pipe will be exposed to the wall surface. 4. The wall of the expansion pipe should not be too loose. The too loose wall has poor bearing capacity, and the expansion nails are easy to fall off when hanging things. 5. The distance between the expansion pipes should not be too close, which will easily lead to cracking, and avoid drilling holes at the edge of the wall, which has poor bearing capacity on the edge of the wall. For novice installations, you can choose an expansion tube with a relatively thicker wall to avoid damage and insecure installation during installation. What are the methods for disassembling the expansion tube: 1. First remove the screw with an electric drill, then knock it in a few times with a hammer, and then use needle-nose pliers to clamp the expansion tube and pull it out. If you can’t pull it, you can shake it more. A few times, so that it is easy to pull out. The purpose of the expansion tube: used to fasten the connection and installation of various small and medium-sized pendant items. Can be used indoors and outdoors. Avoid lifting heavy objects, heavy equipment objects, so as not to cause unnecessary losses. Generally need to use matching self-tapping screws.
