Description

The push-pull type multifunctional screw driver

Technical field

The utility model relates to a kind of screwdriver, relates in particular to a kind of push-pull type multifunctional screw driver.

Background technology

Screwdriver is widely used in the installation and removal of articles for use such as various screw fixed furniture, household electrical appliances as a kind of hardware ﹠ tools commonly used in the daily life.Corresponding to the variety classes of agreeing with screw, screwdriver also can be divided into types such as flat mouth, cross, plum blossom.For reaching purposes such as saving manufactured materials, saving accommodation space, many screwdrivers combinations are in the past replaced by various multifunctional screw driver day by day.

Common multifunctional screw driver of the prior art comprises following two kinds.First kind of screwdriver brachycephaly and multifunctional screw driver that the handle of being with the magnetic force groove is formed by a plurality of band magnetic force, this screwdriver only need take out brachycephaly in use from the receiver that handle carries, be plugged in the polygon groove of handle front end again; Its defective is, runs into two types with under the situation of tightening up a screw in once being used in a plurality of objects and even in an object, and frequent replacing brachycephaly will be made troubles to operation, also can cause time waste to a certain extent.Another multifunctional screw driver promptly adopts the mode of taking in that is similar to Swiss Army Knife, multiple driver bit is folded be accommodated in the cutter hub, outwards extracts during use to get final product; Yet, there is a more fatal defective in this multifunctional screw driver, that is exactly that the many more driver bits of bearer types certainly will the huge more cutter hub of demand, thereby can not be used in narrower operating space, and causes very inconvenience when using screwdriver to apply torsion.

The utility model content

The purpose of this utility model provides a kind of push-pull type multifunctional screw driver, applies difficult problem to solve cutter head replacing inconvenience or the torsion that multifunctional screw driver exists in the prior art.

In order to achieve the above object, the technical solution of the utility model proposes a kind of push-pull type multifunctional screw driver, comprises handle end and operating side,

Described handle end has a plurality of strip grooves and push-and-pull button, and described strip groove is used to place various dissimilar driver bits, and described push-and-pull button then is used for correspondence and controls each driver bit and move forward and backward at the strip groove;

Described operating side and handle end are affixed, and have through hole, prolong corresponding strip groove for described driver bit and stretch out.

In the above-mentioned push-pull type multifunctional screw driver, described strip groove is made up of receiver and elongated open; Described driver bit folding and unfolding in described receiver, and have in the rear end from described elongated open, stretch out and with the affixed projection of described push-and-pull button; The sectional area of described driver bit and push-and-pull button is all greater than elongated open, thereby described push-and-pull button and driver bit are only moved on the length direction of elongated open.

In the above-mentioned push-pull type multifunctional screw driver, the front end of described driver bit is set to the cylinder in regular polygon cross section, and the through hole of described operating side is then corresponding to be set to identical shape, applies torsion when being beneficial to operate.

In the above-mentioned push-pull type multifunctional screw driver, described dissimilar driver bit comprises following any kind: the flat degree of lip-rounding, cross, quincunx.

In the above-mentioned push-pull type multifunctional screw driver, described push-and-pull button is provided with the sign of the corresponding driver bit type of controlling of indication.

In the above-mentioned push-pull type multifunctional screw driver, described push-and-pull button is provided with anti-skidding microgroove or tiny projection.

The push-pull type multifunctional screw driver of technical solutions of the utility model is controlled driver bit by the push-and-pull button and is stretched out from the through hole of operating head or regain, and has saved the step of changing cutter head, and operation is very convenient.

Description of drawings

Fig. 1 is the embodiment stereogram of the utility model push-pull type multifunctional screw driver;

Fig. 2 is the A-A ' profile among Fig. 1 embodiment;

Fig. 3 is the B-B ' profile among Fig. 1 embodiment.

The specific embodiment

Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.

Fig. 1 is the embodiment stereogram of the utility model push-pull type multifunctional screw driver, and as shown in the figure, the multifunctional screw driver of present embodiment comprises: comprise handle end 11 and operating side 12.Handle end 11 has a plurality of strip grooves 13 and push-and-pull button 14; Wherein, strip groove 13 is used for placing various dissimilar driver bits 15 (Fig. 1 is invisible, and as shown in Figure 2), 14 on push-and-pull button is used for correspondence and controls each driver bit 15 and move forward and backward at strip groove 13.Operating side 12 can be affixed by screw with handle end 11, and it has through hole 121, and (invisible among Fig. 1, as shown in Figure 3), the strip groove 13 that prolongs correspondence for driver bit 15 stretches out.

Continuation is with reference to Fig. 2, and it is the profile that A-A ' locates among Fig. 1.As shown in the figure, strip groove 13 is made up of receiver 131 and elongated open 132 (blank space of receiver 131 lines among the figure).Driver bit 15 folding and unfoldings and have projection 151 in the rear end in receiver 131; Projection 151 is stretched out from elongated open 132, and with push-and-pull button 14 affixed (also can be processed as one in concrete the application).It is evident that driver bit 15 and push-and-pull button 14 all should have the sectional area greater than elongated open 132, thereby push-and-pull button 14 and driver bit 15 only can be moved along the length direction of elongated open 132.

In the push-pull type multifunctional screw driver of the foregoing description, the front end of driver bit 15 can be set to the cylinder in regular polygon cross section, and the through hole 121 of operating side 12 then correspondence is set to identical shape, applies torsion when being beneficial to operate.As shown in Figure 3, the profile that it is located for B-B ' among Fig. 1, driver bit front end and 121 of through holes are set to orthohexagonal cross section in the diagram present embodiment.

In addition, in the push-pull type multifunctional screw driver of present embodiment, can be according to the handle end of the different sizes of using of needs design, to place all types of driver bit of varying number, comprise: the flat degree of lip-rounding, cross, quincunx etc., and all types of driver bits that a plurality of different sizes also can be set.

Further modification as the foregoing description push-pull type multifunctional screw driver, the sign of the corresponding driver bit type of controlling of indication can be set on the push-and-pull button 14, then on the push-and-pull button of correspondence, criss-cross sign is set as criss-cross driver bit, thus convenient the use; And, also can be provided for anti-skidding microgroove or tiny projection on the push-and-pull button.Specifically can be referring to shown in Figure 1.

By the foregoing description as can be known, the technical scheme of the utility model push-pull type multifunctional screw driver can be controlled driver bit by the push-and-pull button and stretch out from the through hole of operating head or regain.In use, can be at the screw type of running into, according to the indication that identifies on the push-and-pull button, the corresponding types driver bit that handle end is placed is released from the through hole of operating side, utilize the push-and-pull button driver bit to be regained in the strip receiver of handle end after finishing using equally, thereby saved the step of changing cutter head, and operation is very convenient.

More than be preferred forms of the present utility model, according to the disclosed content of the utility model, those of ordinary skill in the art can expect some identical, replacement schemes apparently, all should fall into the scope of the utility model protection.
