Manufacturing method of expansion screw installation device for military equipment

1. The utility model relates to the technical field of expansion screw installation, in particular to an expansion screw installation device for military equipment.

Background technique:

2. The expansion screw is generally referred to as a metal expansion screw. The fixation of the expansion screw is to use the wedge-shaped slope to promote the expansion to generate frictional gripping force to achieve the fixing effect. ), there are several incisions in the half of the iron cylinder (steel pipe), put them into the hole made on the wall, then lock the nut, the nut pulls the screw out, and the taper is pulled into the iron cylinder, and the iron cylinder is expanded. , so it is tightly fixed on the wall, generally used for the fastening of guardrails, awnings, air conditioners, etc. on cement, brick and other materials, but its fixation is not very reliable, if the load has a large vibration, it may loose It is not recommended for installation of ceiling fans etc.

3. When installing expansion screws, it is often necessary to tap the expansion screws with ordinary hammers or electric hammers. During the tapping process, the staff will be injured due to improper operation, and the tapping process will also affect the expansion screws. Therefore, the market urgently needs to develop an expansion screw installation device for military equipment to help people solve the existing problems.
