[0002] Cough syrup is mainly used to relieve cough and reduce phlegm. It is suitable for colds, coughs, phlegm, bronchial asthma and other symptoms. It is a prescription drug.

[0003] Usually, cough syrup needs to be filled in medicine bottles in the production workshop. For example, the existing medicine filling machine with Chinese patent publication number CN212267955U can enter the installation hole due to the insertion of the limiting protrusion in the guide groove, and cross the limiting protrusion and then be stuck in the limiting groove because it is equivalent to the rotation of the filling frame, thereby realizing the fixed installation of the filling head on the filling frame. This installation method will not release the connection between the filling needle and the filling frame due to the influence of the bottle to be filled, and the limiting protrusion can prevent the limiting protrusion from falling out of the limiting groove, so it can have a better use effect.

[0004] However, the filling activity of this device is complicated, resulting in instability and insufficient reliability. Utility Model Content
