Description

Technical Field

[0001] The utility model relates to a butterfly nut disassembling and assembling tool, in particular to a butterfly nut quick disassembling and assembling tool in a narrow space where human hands cannot operate, and relates to an improvement on the butterfly nut disassembling and assembling tool. Background Art

[0002] As one of the commonly used standard parts, butterfly nuts are involved in various fields such as home appliances, telecommunications and data communications, and automobiles. The butterfly nut is also called a hand-tightening nut. The original intention of the design is that it does not require the use of other tools and can be quickly disassembled and assembled directly by hand. Under special conditions, it avoids the disadvantage of ordinary nuts that require tools to install; however, as its application field becomes more and more extensive, it is inevitable that it needs to be installed in a small space during use, which inadvertently increases the difficulty of installation, reduces the work efficiency of the installer, and disrupts the installation rhythm. Summary of the invention

[0003] The purpose of the present invention is to provide a special tool which can quickly disassemble and assemble a butterfly nut in a narrow space environment, so as to solve the problem that the butterfly nut cannot be directly installed in place by hand due to the small operating space.

[0004] The above-mentioned purpose is achieved through the following technical solutions: a butterfly nut quick disassembly and assembly tool that can be used in a narrow space, comprising an electric ratchet wrench, a disassembly and assembly tool main rod, a disassembly and assembly tool auxiliary rod, and a connecting plate; specifically: a notch is opened at an angle at one end of the disassembly and assembly tool main rod, and a circular hole is opened on the side wall of the other end; a square hole is opened on the connecting plate; the disassembly and assembly tool main rod and the connecting plate are welded at one end close to the circular hole; the two ears of the butterfly nut are placed in the notched end of the disassembly and assembly tool main rod and stuck; the butterfly nut and the screw rod are aligned; the square head of the electric ratchet wrench is inserted into the square hole of the connecting plate, and the switch is pressed to start automatically pre-tightening the butterfly nut assembly; after the pre-tightening is completed, the disassembly and assembly tool auxiliary rod is inserted into the circular hole of the disassembly and assembly tool main rod to final tighten the butterfly nut; the reverse operation can be performed during disassembly.

[0005] The rotating head of the electric ratchet wrench is a square head structure, can be started and stopped immediately, can realize forward and reverse rotation, and runs smoothly and reliably.

[0006] The main rod and auxiliary rod of the disassembly and assembly tool are both commonly used stainless steel pipes and can be made into different sizes as required. The notch on the main rod of the disassembly and assembly tool changes from large to small and can be matched with butterfly nut ears of various specifications.

[0007] The square hole on the connecting plate must match the size of the square head on the electric ratchet wrench. Beneficial Effects

[0008] The utility model is composed of an electric ratchet wrench, a disassembly and assembly tool main rod, a disassembly and assembly tool auxiliary rod, and a connecting plate, and has the characteristics of low cost, wide applicability, and simple operation. BRIEF DESCRIPTION OF THE DRAWINGS
