Detailed description of the invention
Referring to figs. 1 through Fig. 4, the hand-held automatic locking screw machine embodiment of the utility model is described further.
A kind of hand-held automatic locking screw machine, comprise electric screwdriver 1, cylinder 2, dop connecting plate 3 and dop portion, described electric screwdriver 1 is provided with screwdriver bit 11, described cylinder 2 is provided with piston rod 21, described electric screwdriver 1 is fixedly connected with by connecting elements 4 with cylinder 2, one end of described piston rod 21 is fixedly connected with dop connecting plate 3, and described dop portion is arranged on the side of dop connecting plate 3 electric screwdriver 1 dorsad, and described screwdriver bit 11 is provided with safety operation mechanism.
Described safety operation mechanism comprises protection cylinder 51 and handle cylinder 5, and described protection cylinder 51 is arranged on the side in dop connecting plate 3 dop portion dorsad, and is set on screwdriver bit 11, and described handle cylinder 5 is arranged on connecting elements 4, and is set on protection cylinder 51.
