Abstract
The utility model discloses a safety clutch device of an impact electric hammer. The safety clutch device comprises an air cylinder and a steel sleeve gear. A clutch spring is arranged between the air cylinder and the steel sleeve gear. One end of the clutch spring is fixed to the steel sleeve gear, and the other end of the clutch spring is connected to a boss of the air cylinder in a sleeve mode. The safety clutch device of the impact electric hammer has the advantage of being capable of preventing high torque reactive force caused by clamping stagnation of a drill from being transmitted to an operator when the drill is used, thereby guaranteeing safety of the operator.
Description
Technical field
The utility model relates to a kind of impact electric hammer, relates in particular to a kind of impact electric hammer safety clutch device.
Background technology
Electric hammer is the class in electric drill, be mainly used to hole on concrete, floor, brick wall and stone material, because the drill bit of electric hammer has also produced along the fast reciprocating of the direction of electric drill bar when rotating, move (frequent impact), impact and make electric hammer be not easy to control frequently, vibrations are large.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
The purpose of this utility model is to provide a kind of safe impact electric hammer safety clutch device.
The technical solution adopted in the utility model is:
Impact electric hammer safety clutch device, comprise cylinder and steel bushing gear, between described cylinder and steel bushing gear, be provided with brake spring, described brake spring one end is fixed on steel bushing gear, and the described brake spring other end is socketed on the boss of cylinder.
The beneficial effects of the utility model: the large torque reaction power that this safety clutch device avoids in use the clamping stagnation because of drill bit to produce passes to operator, guarantees operator's safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, steel bushing gear, 2, brake spring, 3, cylinder, 4, boss.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, impact electric hammer safety clutch device of the present utility model, comprises cylinder 3 and steel bushing gear 1, between cylinder 3 and steel bushing gear 1, is provided with brake spring 2, brake spring 2 one end are fixed on steel bushing gear 1, and brake spring 2 other ends are socketed on the boss 4 of cylinder 3.
When steel bushing gear 1 surpasses torsion, owing to being provided with brake spring 2 between cylinder 3 and steel bushing gear 1, under the effect of brake spring 2, steel bushing gear 1 directly rotates, and realizes idle running, guarantees that cylinder 3 is normally used, and guarantees electric hammer normal operation.
The large torque reaction power that this safety clutch device avoids in use the clamping stagnation because of drill bit to produce passes to operator, guarantees operator's safety.
Claims (1)
