FIELD: apparatuses for squeezing operated by means of one hand.

SUBSTANCE: electrohydraulic squeezing apparatus includes electric motor 4, transmission mechanism 19, pump 20, hydraulic reservoir 33 and working head 30. Said units 4, 19, 20, 33, 30 are arranged successively one after another in axial direction. Apparatus is provided with portion 5 for gripping it by hand. Portion 5 is matched with starting switch 39 arrangement and it embraces electric motor 4. Switch 39 is arranged at side of electric motor 4 turned to working head. Portion 5 is formed in gravity center of apparatus 1. On mutually opposite sides of housing 3 of apparatus 1 there are mounted starting switch 39 and emergency switch 34 whose positions are matched with places of putting forefinger and thumb respectively. Working piston 16 at working of apparatus is moved at first to stop position and it is kept in such position before moving it to squeezing position. Effort acting upon blank in stop position is significantly less than maximum squeezing effort.
