A tool for assembling a hose and a connector, which includes a base, a hose clamping assembly, a connector clamping assembly and a drive assembly. The base includes an assembly axis . The hose clamping assembly is slidably connected to the base. The connector clamping assembly is rotatably connected to the base and the drive assembly is configured to drive the connector clamping assembly to rotate about the assembly axis while moving toward or away from the hose clamping assembly. The drive assembly drives the connector clamping assembly to perform rotational motion about the assembly axis , while simultaneously moving axially toward or away from the hose clamping assembly, thereby achieving synchronized axial advancement of the connector during rotation. This rotation +linear feed compound motion significantly reduces assembly time and is particularly suitable for precision-demanding rapid assembly applications.

A clamp can include a main clamp body, moving clamp body, a first jaw and a second jaw. The moving clamp body can be supported by and movable relative to the main clamp body. The first jaw can be connected to the main clamp body and rotatable relative to the main clamp body. The second jaw can be connected to the moving clamp body and rotatable relative to the moving clamp body. The clamp can further include a pin connected to the main clamp body so that the main clamp body and the pin can rotate relative to one another. The clamp can further include am adapter connected to the pin so that the adapter and the pin can rotate relative to one another. Rotational motion of the jaws, the main clamp body and the pin, and the pin and the adapter can be locked independently of one another.
