Description

Technical Field

[0001] This utility model relates to the field of disassembly tools, and more specifically, to a nut quick-release and disassembly device. Background Technology

[0002] There are two main methods for nut removal and installation: one is to manually remove or install nuts using a wrench, and the other is to use a nut removal and installation machine for automatic removal and installation. However, these two methods are not suitable for nuts in certain special locations, such as when space is limited and it is not appropriate to use a wrench. Using these methods has disadvantages such as difficulty, low efficiency, and poor portability.

[0003] The utility model application with patent number CN201920416744.X discloses a quick-release nut assembly / disassembly device, including a pneumatic motor, a sleeve, and a foot switch, as well as a silencer. The pneumatic motor is mounted inside the silencer via a support plate, and its output end extends out of the silencer and is detachably connected to the sleeve. The pneumatic motor is connected to the foot switch via an air pipe. Multiple support rods are hinged to the periphery of the support plate, and each support rod is slidably mounted on the bottom of the silencer via a slider. A vibration-damping spring is also provided between the support plate and the bottom of the silencer. This assembly / disassembly device is compact, easy to use, and can quickly assemble and disassemble nuts, effectively reducing vibration and noise generated during the assembly / disassembly process, ensuring operator safety, and is characterized by convenient operation, wide applicability, and high efficiency.

[0004] The aforementioned application document proposes a quick nut removal and installation device. However, when removing and installing nuts, some nuts are located in small or special positions where sockets cannot be used for removal, requiring open-end wrenches. The difficulty in using wrenches and sockets makes nut removal and installation challenging for workers. Therefore, to address the above-mentioned problems, the proposed device is compact, easy to operate, and portable, thus overcoming the shortcomings of existing nut removal and installation tools and improving upon the aforementioned issues.
