Abstract
The invention relates to an impact-resistant electric screwdriver. The impact-resistant electric screwdriver comprises a connecting column and a working head which is at least arranged at one end of the connecting column. An elastic buffer part is arranged at least in the position for assembling on the connecting column. Compared with the prior art, the gap between the connecting column and a connecting hole can be narrowed by arranging the elastic buffer part, the buffer effect is effectively achieved, and the wobbling and impact of the electric screwdriver are reduced in the using process, so that the operation quality is guaranteed and the service life of an electric tool is prolonged.
Description
Technical field
The present invention relates to electric screwdriver head field, more particularly to a kind of impact-resistant electric screwdriver head.
Background technology
Screwdriver bit is often referred to be installed to the driver bit of the turn of the screw above electric hand drill or electric hammer, by different types, can be with
It is divided into a word, cross, rice word, star-like, square toes etc..When using, electric screwdriver head is attached in the connector of the instruments such as electric hand drill, beaten
Switch, electric screwdriver head starts operation under power drives.Compared with traditional hand-operated tools, electric tool has operating efficiency
High, easy to use the advantages of, the favor of operator is therefore suffered from, be especially widely used on assembly belt.
However, electric screwdriver head is detachable with the connection of the connector of electric hand drill, select assembling suitable when using as needed
The electric screwdriver head of conjunction, after certainly will so making to have installation gap, and long-time use between electric screwdriver head and the connecting hole of connector,
Electric screwdriver head and connecting hole can wear and tear, so that installing gap increase, excessive installation gap can use electric screwdriver head
Vibratility, impact increase in journey.Additionally, when electric screwdriver head manipulating object for hardness is bigger object when, hard objects it is anti-
Active force can cause certain impact to electric screwdriver head and electric hand drill in itself.Excessive impact, can not only influence the work of electric screwdriver head
Industry quality, and service life that can be because of excessive vibrations to electric hand drill impacts.
The content of the invention
The technical problems to be solved by the invention are directed to prior art and provide a kind of energy effective shock, impact-resistant electricity
Screwdriver bit.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of impact-resistant electric screwdriver head, including connection
Post and the work head for being arranged at the connecting pole one end, it is characterised in that at least in the position for assembling on the connecting pole
The place of putting is provided with resilient snubber.
Preferably, the resilient snubber is set in the periphery of connecting pole along connecting pole length direction, so that elastic
The shockproof of bolster, impact resistance are more preferable,.
Preferably, the two ends of the connecting pole are respectively arranged with spacing preiection, the resilient snubber is spacing in both sides
Spacing preiection between so that resilient snubber is firmly placed on connecting pole.
Preferably, the spacing preiection is circumferentially stretched out by connecting pole forming.
Preferably, the longitudinal section of the connecting pole where the spacing preiection is in regular polygon shape, limit convex can not only be made
Rise preferably carries out spacing to resilient snubber, and can be assembled with the connecting hole of electric hand drill by the spacing preiection.
Preferably, the resilient snubber at least one end set is buckled on above-mentioned spacing preiection；Or, the elasticity
Bolster at least one end is fixed on above-mentioned spacing preiection.So that resilient snubber is more firmly mounted to above-mentioned connecting pole
On.
Preferably, the resilient snubber is spring, selection spring is used as the resilient snubber in the present invention, structure letter
It is single, convenient processing, and preferable shockproof, shock resistance effect can be reached.
Compared with prior art, the advantage of the invention is that：Resilient snubber is provided with the connecting pole of electric screwdriver head, the bullet
Property the bolster gap shrinks that can make between connecting pole and connecting hole, effectively play cushioning effect, reduce electric screwdriver during use
The rocking property and impact of head, so as to ensure to operate quality, extend the service life of electric tool.
Brief description of the drawings
Fig. 1 be the embodiment of the present invention in be provided with electric screwdriver head electric hand drill structural representation；
Fig. 2 is the enlarged drawing of I part in Fig. 1；
Fig. 3 is the structural representation of electric screwdriver head in the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 3, a kind of impact-resistant electric screwdriver head, it includes connecting pole 3 and is arranged at the connecting pole 3 one
The work first 4 at end, the i.e. electric screwdriver head can be single head screwdriver bit or double end screwdriver bit, and above-mentioned work first 4 can be a word, cross, rice word, star
Any one in type, square toes etc., can be selected according to operation needs.
It is as shown in Figure 1 the electric hand drill 1 of the electric screwdriver head being provided with the present invention, connector 2 is provided with the electric hand drill 1,
Electric screwdriver head is arranged in the connecting hole 21 of the connector 2.In the present embodiment, on connecting pole 3 at least at the position for assembling
It is provided with resilient snubber 5, the resilient snubber 5 is spring 5 (preferably, the spring is compression spring).Resilient snubber 5
Set, the gap shrinks between connecting pole 3 and connecting hole 21 can be made, and can effectively play cushioning effect, during reduction use
The rocking property and impact of electric screwdriver head.To make the shockproof of resilient snubber 5, impact resistance more preferable, it is preferable that resilient snubber
5 peripheries that connecting pole 3 is set in along the length direction of connecting pole 3.
Further, to make resilient snubber 5 be firmly placed on connecting pole 3, it is preferable that the two ends difference of connecting pole 3
Spacing preiection 31 is provided with, resilient snubber 5 is spacing between the spacing preiection 31 of both sides.Specifically, it is spacing in the present embodiment
Raised 31 are circumferentially stretched out by connecting pole 3 forms.Additionally, the longitudinal section of the connecting pole 3 where spacing preiection 31 is in just more
Side shape, while above-mentioned connecting hole 21 matches and in regular polygon shape with the spacing preiection 31, during assembling, as needed by it
The spacing preiection 31 of middle side is arranged in connecting hole 21, so as to complete electric screwdriver head be assembled with electric hand drill 1.
Further, to make resilient snubber 5 more be firmly mounted on above-mentioned connecting pole 3, resilient snubber 5 is at least
One end set is buckled on above-mentioned spacing preiection 31, or, at least one end of resilient snubber 5 is fixed on above-mentioned spacing preiection 31.This
In embodiment, the two ends of resilient snubber 5 cover be buckled on the spacing preiection 31 at two ends respectively.
