Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 to Fig. 5, in the present embodiment, a kind of quick change impacting head assembly for electric hammer includes phase interworking
The quick change impact shaft assembly 1 and quick change impacting head assembly 2 of conjunction, the quick change impact shaft assembly 1 include the hollow He of impacting shaft 10
Hammer post 11 into shape, the hammer post 11 is installed in the impacting shaft 10, and two are telescopically provided with the outer wall of the impacting shaft 10
Spacing steel ball 12, and opened up on the side wall of the impacting shaft 10 in jagged 13, the breach 13 and be arranged at anti-rotation steel column 14, institute
The outside for stating anti-rotation steel column 14 is provided with to be provided with the both sides of the locating ring 15 on locating ring 15, the impacting shaft 10 and is used for
The back-up ring 16 positioned to locating ring 15.
The quick change impacting head assembly 2 includes hollow impact head 20, and the end of the impact head 20 is provided with fixing end
The movable end cover 22 worked in coordination and positioning end cap 23 are provided with outside lid 21, and the impact head 20, the movable end cover 22 can
