Description

Rotary wheel changeable multipurpose screwdriver

The utility model relates to a kind of combination tool of safe ready, i.e. the interchangeable multi-purpose screwdriver of runner.

A kind of combined screwdriver is arranged at present, and the handle base portion of this screwdriver has a room with end cap, lays the different knife bar of some edges of a knife therebetween, and during work, the required knife bar of manual taking-up is changed.There are some shortcomings like this in this combined screwdriver: the one, and more changing knife rod is loaded down with trivial details, and the time is long; The 2nd, lack security, lose other knife bar during replacing easily; Three are to use inconvenience, lack mobility.

The purpose of this utility model provides a kind of more changing knife rod simple, convenient and rapid with regard to being to overcome the shortcoming of prior art, and is safe and reliable, and moving novel combination type instrument---the interchangeable multi-purpose screwdriver of runner easily of using time.

The utility model is to adopt following measure to realize its purpose.

The utility model that is formed by connecting by main body, handgrip, guiding rotating shaft and runner, circumference has and can lay the variform knife bar through hole of the various edges of a knife on its runner, runner embeds in the groove of main body, and can rotate around the guiding rotating shaft of being fixed on the main body, slide in the guiding counterbore of guiding rotating shaft in handgrip, settle the push-and-pull locking bar in the through hole that is interspersed on the runner on the handgrip.The front and rear of push-and-pull locking bar respectively has a groove, settles a detent mechanism of being made up of gland, backstay and spring on main body.The push-and-pull locking bar is a magnetic material.The afterbody of the variform knife bar of the edge of a knife has inner hexagonal hole, and it is the knife bar of outer-hexagonal that an edge of a knife is arranged in the knife bar.Through hole on the runner is hexagon or interior square.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structure cutaway view of the present utility model;

Fig. 2 is the cutaway view along A-A direction among Fig. 1;

Fig. 3 is the assembling relationship figure of the utility model parts;

Fig. 7 utilizes the edge of a knife to be the extend use installation diagram of other knife bar active length of the knife bar of outer-hexagonal shape.

Below in conjunction with accompanying drawing the utility model is described further.

The utility model is by the main body (5) with groove breach (4), the handgrip (12) that has guiding counterbore (11), circumference has the runner (2) of the through hole (3) that can lay the variform knife bar of the various edges of a knife (1), and guiding rotating shaft (10) is formed by connecting, guiding rotating shaft (10) is fixed on the main body (5), runner (2) rotates around guiding rotating shaft (10) in the groove breach (4) of main body (5), guiding rotating shaft (10) can be slided in the guiding counterbore (11) in the handgrip (12), fix a push-and-pull locking bar (9) on the handgrip (12), push-and-pull locking bar (9) interts in each through hole (3) in runner (2).Push-and-pull locking bar (9) is a magnetic material, respectively have a groove (14) (15) in its front-end and back-end, settled a detent mechanism of forming by gland (8), backstay (7) and spring (6) at the back of main body (5), also have a groove (13) on the backstay (7), the position between incompatible definite main body (5) and the handgrip (12) that matches of the groove (14) (15) on groove on the backstay (7) and the push-and-pull locking bar (9).Can lay the different various knife bars of quantity in the runner (2).Present embodiment is to have laid six kinds of knife bars, and they are respectively flat mouthful screwdriver, Phillips screwdriver, scriber, outer-hexagonal screwdriver, many ribs scraper and triangle reamer.The afterbody of every kind of knife bar (1) has an inner hexagonal hole (17), owing to the effective active length that is used the knife bar that can also extend of every knife bar afterbody inner hexagonal hole and outer-hexagonal screwdriver (16).Through hole (3) on the runner (2) is complementary with various knife bars (1) can make hexagon or square.During use, at first push backstay (7), both hands draw back main body (5) and handgrip (12), unclamp backstay (7), make groove on the backstay (7) location of matching with groove on the push-and-pull locking bar (9), rotating wheel (2) selects required knife bar corresponding with push-and-pull locking bar (9), press and press backstay (7), both sides are to pushing away main body (5) and handgrip (12) makes it to close up, unclamp backstay (7) and make main body (5) and handgrip (12) location, at this moment, required knife bar just reveals, because push-and-pull locking bar (9) is a magnetic material, so, the knife bar that manifests can not drop out in use, and when separating main body (5) and handgrip (12), and the knife bar that reveals can be retracted in the through hole (3) on the runner (2) by magnetic push-pull locking bar (9).

The utility model is simple in structure, uses motor-driven convenience, and more changing knife rod is simple, convenient and rapid, and is safe and reliable.
