Background technology
In the existing domestic and international hand-held electric hammer product, the cutter chuck assembly all utilizes due spacing motion difference in height of steel sphere lock body and the combined structure of cylinder locking circle.Realize the locking of steel sphere lock body and come off according to the required chuck cover manually pulled of dismounting.During the clamping cutter, manually the chuck cover is moved to spacing place backward, then interlock locking circle breaks away from steel sphere lock body, and it is that the stage clip counter-force resets that cutter is inserted in its hole, and interlock locking circle is with the locking of steel sphere lock body, and then cutter is in the lock state.Taking out cutter according to the same operation sequence gets final product.This shows that the mounting or dismounting cutter needs secondary to pull the chuck cover.
Summary of the invention
Deficiency at above-mentioned existing structure, the utility model adopts two kinds of different typical motion mechanisms, use the principle at required working depth difference movement locus of steel sphere lock body and axial lock pressure angle respectively, once realize the function that cutter is locked and comes off.
Adopt the technical solution of the utility model, manually only need once pull the chuck cover, can realize, and cutter inserts and automatically lock, improved the reliability of release cutter locking and the dismounting function that comes off.
A kind of improved hand-held electric hammer of cutter chuck that relates to of the present utility model, described cutter chuck comprises:
The locking circle, main body is the open circles ring-type, the one end is a planar end surface, the other end is a taper seat, form a circular datum hole in the described torus and on the vertical center line of described datum hole, if the protruding flat key that straight line guiding is required on torus cylindrical vertical center line, is provided with section configuration by the conical surface and face the groove of forming directly;
Stage clip comprises the main body of a cylindrical stage clip, is provided with an inclined working that takes the shape of the letter U at an end of cylindrical stage clip;
Clamp body comprises roughly being on the cylindrical clamp body main body, offers an elongated slot along centerline direction, is that sphere shape is step-like around the bottom land, and its same vertical center line bottom cylindrical is provided with the required flat key groove of straight line guiding; Wherein,
In the described stage clip front end centre position U-shaped inclined working be arranged in the elongated slot of described clamp body and with the groove of described locking circle in spacing the connection, datum hole in the described locking circle and flat key respectively with described clamp body on the diameter of axle flat key groove relative position location match.
