Abstract

The utility model discloses a quick-assembly and quick-disassembly connecting tool for connecting a plug box to a bus, which comprises a frame body, a driving handle, clamping arms and a transmission assembly, wherein the frame body can be used for semi-surrounding and accommodating the plug box, the driving handle can penetrate through the frame body and protrude out of the surface, the clamping arms can be folded to tightly clamp the bus in pairs, the transmission assembly is positioned in the frame body and plays a role in transmission between the inner end of the driving handle and the clamping arms, and the transmission assembly is provided with a retrograde self-locking mechanism. The driving handle is screwed, and power is transmitted to the clamping arm through the transmission assembly, so that the clamping arm can be folded quickly to hold the bus tightly. The retrograde self-locking mechanism prevents the retrograde power transmission, so that the clamping arm cannot be opened independently, self-locking is realized, and the clamping arm always holds the bus tightly to avoid loosening. The manual reverse screwing driving handle can unlock and drive the clamping arm to open quickly, and then the jack box can be taken down.
