Abstract

The invention discloses a trigger type clutch mechanism and filling equipment. The trigger type clutch mechanism comprises a transmission assembly, a trigger assembly, a holding piece and a fixing base. The transmission assembly comprises a limiting plate, a first guide rod, a lead screw, a clutch clamping jaw, a bearing sliding block, a pushing assembly and an abutting plate. The near end of the pushing assembly is fixedly connected with the clutch clamping jaw and the bearing sliding block, and the clutch clamping jaw is provided with meshing threads matched with the lead screw. The far end of the pushing assembly extends into the holding piece and is fixedly connected with the abutting plate. The trigger assembly comprises a first elastic assembly and a second elastic assembly. The clutch mechanism is arranged in the filling equipment, so that the filling precision of the filling equipment can be improved, and the safety and the use flexibility of the filling equipment when a containing container is not mounted are realized.

Description

technical field [0001] The embodiments of the present invention relate to the field of mechanical equipment, in particular to a trigger clutch mechanism and pouring equipment. Background technique [0002] A perfusion system is a tool for injecting a volume of liquid or gas into a target. Usually, the perfusion system includes a perfusion device and a container, which cooperate with each other, and the perfusion device is used to manipulate the container to complete the perfusion action. For example, the holding container can be a syringe, which can store liquid or gas. The syringe includes a cylinder body and a piston rod. The piston rod is arranged in the cylinder body to perform piston movement. Piston movement relative to the barrel for perfusion. [0003] The perfusion equipment in the prior art generally includes: a driving mechanism and a holding member, both of which are linked to each other, and the driving mechanism is used to drive the holding member to move, so...
