Technical Field

The utility model relates to a screwdriver, more specifically says, relates to a multifunctional screwdriver.

Background

At present, the function of the screwdriver is single, and with continuous progress of industrial manufacturing industry, workpieces need bolts or screws of different types and different types to fasten workpiece structures, for example, some hexagon bolts and the like need hexagonal sleeves and the like to fasten or disassemble, if the function is single, more tools need to be carried, so that inconvenience is brought to workers, time for finding the tools is wasted, and working efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art's is not enough, provides a multifunctional screwdriver, combines the sleeve structural at the screwdriver, increases its functionality and practicality.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a multifunctional screwdriver, it includes handle, cutter arbor and tool bit, the handle is connected with the cutter arbor, the tool bit can be dismantled with the cutter arbor and be connected, the cutter arbor on the cover be equipped with the sleeve piece of rectangular structure, sleeve piece is equipped with the spline sleeve of different specifications respectively with cutter arbor axial direction parallel's side.

Preferably, the cutter bar is connected with the sleeve block through a bearing, and a limiting groove for limiting the position of the bearing is formed in the cutter bar along the circumferential direction.

Preferably, the sleeve block is arranged in the middle of the cutter rod.

Preferably, the cutter head is of a straight-line or cross-shaped structure.

Preferably, tool bit one end be equipped with the embedded groove, the cutter arbor tip be equipped with the embedded groove cooperation be connected the embedding pole, the tool bit be close to the tip of embedded groove is the magnetic metal material.

Preferably, the embedded groove is a pentagonal groove body or a hexagonal groove body, and the embedded rod is of a pentagonal structure or a hexagonal structure matched with the embedded groove.

Preferably, the handle is in a lantern structure with two sides gradually higher towards the middle.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure, reasonable in design sets up the spline sleeve of different specifications size through the sleeve piece, can cooperate the bolt or the screw of multiple specification to set up the sleeve piece on the cutter arbor of screwdriver, increased the functional and the practicality of screwdriver, make the user work of facilitating more.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description below:

referring to fig. 1, the multifunctional screwdriver comprises a handle 2, a screwdriver rod 1 and a screwdriver head 3, wherein the handle 2 is connected with the screwdriver rod 1, in this embodiment, the handle 2 is detachably connected to the cutter bar 1, the cutter head 3 is detachably connected to the cutter bar 1, referring to fig. 2, one end of the cutter head 3 is provided with an embedded groove 30, the end of the cutter bar 1 is provided with an embedded rod 10 which is connected to the embedded groove 30 in a matching manner, the end of the cutter head 3 close to the embedded groove 30 is made of magnetic metal material, the magnetic metal material can be made of magnetic alloy steel, preferably, the embedded groove 30 is a pentagonal groove body or a hexagonal groove body, the embedded rod 10 is a pentagonal structure or a hexagonal structure matched with the embedded groove 30, so that the connection between the tool bit 3 and the tool bar 1 is more compact and the combination is firmer, the tool bit 3 is in a straight line shape or a cross shape, when the tool bit 3 needs to be replaced, the tool bit 3 can be pulled out, and replacement is more convenient.

In this embodiment, fully consider that the workman will go to twist the bolt of multiple specification or different grade type when fastening or dismantling the work piece, as preferred, the cover is equipped with the sleeve piece 4 of rectangular structure on the cutter arbor 1, refer to fig. 2, sleeve piece 4 is equipped with the spline sleeve 40 of different specifications respectively with cutter arbor 1 axially parallel's side, with the bolt of the different specifications of adaptation, when for letting the workman be in the use, it is more convenient, need not alternate cutter arbor 1 position back and forth, in this embodiment, as preferred, refer to fig. 3, be connected through bearing 42 between cutter arbor 1 and the sleeve piece 4, sleeve piece 4 is the axial rotation of relative cutter arbor 1, when needing to use the spline sleeve 40 of different specifications, can rotate sleeve piece 4, make labour saving and time saving more.

In this embodiment, the sleeve block 4 is disposed in the middle of the cutter bar 1, and when the sleeve block 4 is needed, the handle 2 or two ends of the cutter bar 1 can be used for assisting power, so that more labor is saved, referring to fig. 4, and the cutter bar 1 is provided with a limiting groove 41 for limiting the position of the bearing 42 along the circumferential direction, so that the bearing 42 and the sleeve block 4 can be prevented from moving arbitrarily.

In this embodiment, as preferred, handle 2 is the lantern type structure that both sides are gradually high to the centre, and the workman of being convenient for is handheld, and the structure is pleasing to the eye.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
