Description

A kind of multifunctional screw driver

Technical field

The utility model belongs to machine tool technical field, and in particular to a kind of multifunctional screw driver.

Background technology

Screwdriver has turned into the necessary article of every family, and it can easily dismount common various spiral shells in home appliances Silk.Screwdriver on the market is various now, the need for meeting people's daily life, and structurally and functionally increasingly It is perfect, but the practicality of screwdriver does not obtain very big performance.Screwdriver common on the market is most of by knife bar and knife Head is connected as a single entity, and can only be used for dismounting a kind of screw of fixation, and versatility is not strong, in order to complete a dismounting job, in family Multiple screws knife is got out, unnecessary expenditure is increased, operating efficiency is very low, often twisted perhaps for screw more long Multi-turn could realize assembly and disassembly, waste time and energy.Therefore, people meet work in the urgent need to a kind of fast and easily multifunctional screw driver Industry requirement.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of fast and easily Multifunction screw Knife.

In order to reach above-mentioned purpose of design, the technical scheme that the utility model is used is：A kind of multifunctional screw driver, bag Handle of a knife, knife bar, crank are included, the handle of a knife outer wall offers draw-in groove, and the handle of a knife left end is provided with tool magazine, handle of a knife inside right-hand member Two adjacent bearing decks I are provided with, the bearing deck I is installed with bearing I, the bearing I and is set with knife bar, the knife The left end of bar is set with tapered gear I, and the knife bar right-hand member is provided with cutter head deck, and handle of a knife inside stage casing is provided with bearing deck II, it is installed with the bearing deck II and power transmission shaft is set with bearing II, the bearing II, power transmission shaft middle part suit There is tapered gear II, the tapered gear II is connected with the engagement of tapered gear I, the power transmission shaft top is provided with crank connecting seat, The crank is made up of rocking bar, rocking handle, and one end of the rocking bar is articulated with crank connecting seat, and the other end of the rocking bar is hinged There is rocking handle.

The handle of a knife is that two symmetrical semicircles are combined.

The crank is installed in the draw-in groove that handle of a knife surface opens up when not in use.

Magnet is provided with the cutter head deck.

The utility model beneficial effect：In can be collected in for different types of cutter head by the tool magazine that handle of a knife left end is set, with side Just user's quick-replaceable and storage, the crank of clamp is after fastening in the draw-in groove that handle of a knife surface opens up, you can realize common spiral shell The function of silk knife, when workload is larger, crank can be plucked out from the draw-in groove of handle of a knife, by rotating crank, drive tapered teeth Wheel II is rotated, and in tapered gear II and the engaged transmission of tapered gear I, lateral rotation is changed into vertical direction and is rotated, band moving knife Bar is rotated, and realizes that driver bit is rotated, you can the work that the magnet set in rapid-assembling/disassembling screw, cutter head deck attracts by magnetic With driver bit can be made closely coupled with deck to the end.The utility model compact conformation, reliable operation, efficiency high, can be to various Conventional screw is dismantled and installed, and improves operating efficiency and accuracy, while expanding range of application.

Brief description of the drawings

Fig. 1 is a kind of multifunctional screw driver structural representation of the utility model.

Specific embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1：A kind of many work( Energy screwdriver, including handle of a knife 1, knife bar 2, crank 3, the outer wall of the handle of a knife 1 offer draw-in groove, and the left end of the handle of a knife 1 is provided with tool magazine 4, the inside right-hand member of the handle of a knife 1 is provided with two adjacent bearing decks I 5, and the bearing deck I 5 is installed with bearing I 6, the axle Hold in I 6 and be set with knife bar 2, the left end of the knife bar 2 is set with tapered gear I 7, and the right-hand member of the knife bar 2 is provided with cutter head deck 8, The inside stage casing of the handle of a knife 1 is provided with bearing deck II 9, the bearing deck II 9 and is installed with bearing II 10, the bearing II Be set with power transmission shaft 11 in 10, the middle part of the power transmission shaft 11 is set with tapered gear II 12, the tapered gear II 12 with it is tapered The engagement connection of gear I 7, the top of the power transmission shaft 11 is provided with crank connecting seat 13, and the crank 3 is made up of rocking bar 14, rocking handle 15, One end of the rocking bar 14 is articulated with crank connecting seat 13, and the other end of the rocking bar 14 is hinged with rocking handle 15.

The handle of a knife 1 is combined for two symmetrical semicircles.

The crank 3 is installed in the draw-in groove that the surface of handle of a knife 1 opens up when not in use.

Magnet is provided with the cutter head deck 8.

When the utility model is used:During assembly and disassembly screw, suitable cutter head is chosen from screwdriver tool magazine 4 first, be attached to knife In the six corner angle edges of a knife of the cutter head deck 8 of bar 2, because the attraction of magnetic makes driver bit closely coupled with cutter head deck, work as work When amount is few, crank 3 is installed in the draw-in groove that the surface of handle of a knife 1 opens up, because the rotation of knife bar 2 is stuck in screwdriver handle of a knife 1 Crank 3 pin, you can realize the function of normal screws knife, when workload is larger, can by crank 3 from the draw-in groove of handle of a knife scratch Go out, by rotating crank 3, drive the tapered rotation of gear II 12, tapered gear II 12 and the engaged transmission of tapered gear I 7, make transverse direction Rotation is changed into vertical direction rotation, drives knife bar 2 to rotate, and realizes that driver bit is rotated, you can rapid-assembling/disassembling screw.
