The utility model provides a pulse type injector propelling device and pulse type automatic injection equipment. The pulse type injector propelling device comprises a needle cylinder fixing mechanism, a piston rod driving mechanism and a pressure sensor. The piston rod driving mechanism comprises a grabbing and buckling unit, a connecting unit and a driving unit, the end of a piston rod of the injector can be grabbed and buckled through the grabbing and buckling unit, the grabbing and buckling unit is driven by the driving unit to move towards a needle cylinder or move in the direction away from the needle cylinder, and therefore automatic pushing and automatic drawing back of the piston rod of the injector are achieved. Therefore, medical staff can conveniently observe the blood resorption condition through the automatic resorption function, and whether a syringe needle enters a great vein blood vessel or not is judged. Furthermore, due to the fact that a pressure sensor is further arranged, the pressure in
