Abstract

The invention discloses a chuck used for a speed-changing electric drill. The chuck comprises a connecting rod, one end of the connecting rod is detachably connected with a first sleeve, and one end of the first sleeve is movably connected with a clamping claw. The first sleeve is sleeved with a second sleeve in a tightening mode. Multiple grooves are formed in one end, close to the clamping claw, of the outer surface of the first sleeve. A fastening handle is arranged on one groove in a separable mode, teeth on the fastening handle are meshed with teeth on the sleeve, and the first sleeve and the second sleeve are made of high-speed steel. According to the chuck used for the speed-changing electric drill, because the fastening handle used for tightening the sleeves is arranged in a matched mode, the clamping claw can fix a drill bit very firmly, the using efficiency of the electric drill is greatly improved, and safe and reliable effects are achieved.

Description

A kind of speed change electric drill dop
Technical field
The present invention relates to a kind of electric drill dop, or rather, is a kind of speed change electric drill dop.
Background technology
Electric drill is the boring bar tool that power is done in electricity consumption.Being the conventional products in electric tool, is also the electric tool series products having the call.Electric drill is extensively used in the boring of the materials such as woodenware, steel, alloy.Electric drill is distinguished according to drive manner, can be divided into single rotating speed electric drill and speed change electric drill.
In the use engineering of speed change electric drill, because dop tightens by staff, gripper jaw clamping is firm not, due to the variation of speed, thereby easily causes the loosening of gripper jaw on electric drill dop, affects electric drill operating efficiency, easily causes the injury to operator.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of speed change electric drill dop that can very firmly be tightened is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of speed change electric drill dop, comprise a connecting rod, one end of described connecting rod removably connects one first sleeve pipe, one end of the first described sleeve pipe is provided with a gripper jaw movably, on the first described sleeve pipe, can tighten and be socketed one second sleeve pipe, the outer surface of the first described sleeve pipe is provided with several grooves in one end of the gripper jaw near described, on one of them groove, be provided with separably a pinch grip, the mutual interlock of teeth on the teeth on described pinch grip and described the second sleeve pipe.
As preferred embodiment of the present invention, the first described sleeve pipe and the second sleeve pipe are that high-speed steel is made.
Due to the supporting pinch grip that is provided with of dop for speed change electric drill of the present invention, and the mutual interlock of teeth on teeth and the second sleeve pipe on pinch grip, thereby can change the tight ness rating between the first sleeve pipe and the second sleeve pipe by adjusting pinch grip, thereby allow gripper jaw can firmly fix very much drill bit, thereby greatly improve the service efficiency of electric drill, safe and reliable.
    
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of speed change electric drill of the present invention dop;
Fig. 2 is the perspective view of the speed change electric drill dop in Fig. 1, is now another visual angle.
 
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides a kind of speed change electric drill dop that can very firmly be tightened.
As shown in Figure 1 and Figure 2, dop 1 for speed change electric drill, comprise a connecting rod 2, one end of described connecting rod 2 removably connects one first sleeve pipe 31, one end of the first described sleeve pipe 31 is provided with a gripper jaw 32 movably, on the first described sleeve pipe 31, can tighten and be socketed one second sleeve pipe 33, the outer surface of the first described sleeve pipe 31 is provided with several grooves 4 in one end of the gripper jaw 32 near described, on one of them groove 4, be provided with separably a pinch grip 5, the mutual interlock of teeth on the teeth on described pinch grip 5 and described the second sleeve pipe 33.
This speed change electric drill dop, the first described sleeve pipe 31 and the second sleeve pipe 33 are made for high-speed steel.
The speed change electric drill of this invention is provided with the pinch grip that can be used for tightening sleeve pipe with dop is supporting, thereby allows gripper jaw can firmly fix very much drill bit, thereby has greatly improved the service efficiency of electric drill, safe and reliable.
Below only with an embodiment, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more functional module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
