Abstract

The utility model relates to a multi-functional screwdriver used for machining, maintenance, assembly and repair of appliances and furniture in daily life, which integrates various functions of traditional screwdrivers and realizes multipurpose of one article. The technical scheme includes that the screwdriver consists of a hexagonal socket handle, a connecting tube and a screw rod, wherein the hexagonal socket handle is formed by an allen wrench which is 6-milimeter long in opposite side sizes, the cross section of the connecting tube is a regular hexagonal column and internal holes at two ends of the connecting tube are regular hexagonal. An edge of the screw rod is cross-shaped or slotted, each shape of the edge of the screw rod is provided with six different sizes, and the head of the screw rod is regular hexagonal. The hexagonal socket handle is connected with the internal hole at the upper end of the connecting tube, and the screw rod with the edge is connected with the internal hole at the lower end of the connecting tube. The multipurpose screwdriver is small in size, convenient to carry, capable of dismounting screws easily and dismounting screws on two close plates, and can be used for screwing or dismounting flat screws and cross-head screws.

Description

A kind of multifunctional screw driver

Technical field

The utility model relates to a kind of multifunctional screw driver that is used for machining and maintenance, daily life household electrical appliances, furniture finishing.

Background technology

Screwdriver is a very important hardware ﹠ tools in people's live and work.Along with the progress of industrial expansion and science and technology, screwdriver still has very big effect, arrive the manufacturing of aircraft, rocket greatly, can both see the shadow of screwdriver to the maintenance of clock and watch, mobile phone for a short time, and the effect of bringing into play.Conventional screw-driver in order is by handle and revolve tool and constitute, and according to the difference of screwdriver head model, can be divided into a word, cross, and the rice word, T type (blossom type), H type different model screwdrivers such as (hexagonals), these screwdrivers are respectively applied for different field.Modal is a word and Phillips screwdriver, and its function singleness is mainly used in the installation and removal of screw.Because function singleness when needs are finished the dismounting of device, needs to prepare the screwdriver of different size, this has brought a lot of inconvenience to the master worker.In addition, the conventional screw-driver in order arm of force is less, relatively requires great effort when the dismounting screw.When the screw between the plate that needs two distances of dismounting relatively to lack, because the handle of conventional screw-driver in order and swing arm are point-blank, handle and swing arm length sum are longer, and size is bigger, and inconvenience maybe can't be finished the screw dismounting.If we can unite the function of multiple screwdriver, realize one-object-many-purposes, make screw driver handle vertical simultaneously with swing arm, both can increase the arm of force, can finish the installation and removal of the screw between the two short distance plates again; When independent use handle, can finish the installation and removal of opposite side size 5mm and 6mm soket head cap screw; When handle and the supporting use of tube connector, can finish the installation and removal of opposite side size 5mm and 6mm outer-hexagonal screw.

Summary of the invention

The purpose of this utility model is: for each function with conventional screw-driver in order is integrated in one, realize one-object-many-purposes, reduce and carry the loaded down with trivial details of multiple screwdriver, simultaneously in order to remedy the deficiency of conventional screw-driver in order moment of torsion, solve conventional screw-driver in order and can not finish the problem of the screw dismounting between the two short distance plates, the spy provides a kind of multifunctional screw driver.

It is vertical with swing arm that the utility model is designed to screw driver handle, both can increase the arm of force, reach the labor-saving effect, can shorten the vertical range between screwdriver tip and the handle again, finish the screw dismounting between the two short distance plates, during the supporting use of handle and tube connector, can be used as box spanner dismounting outer-hexagonal screw.

In order to achieve the above object, the utility model by the following technical solutions: a kind of multifunctional screw driver is made of interior hexagonal handle, tube connector, swing arm.Its architectural feature is: interior hexagonal handle is made by the inner hexagon spanner that opposite side is of a size of 6mm, and long arm end is set to the inner hexagon spanner that opposite side is of a size of 5mm; Tube connector is that the cross section is orthohexagonal cylinder, and the tube connector two ends are orthohexagonal hole, and the opposite side in hole is of a size of 5mm or 6mm; The cutting edge of swing arm is two types of cross and words, and every type has six kinds of different sizes, and the swing arm head is a regular hexagon, is 5mm to the length of side; Interior hexagonal handle is connected with the endoporus of tube connector upper end, and the swing arm of band cutting edge is connected with the endoporus of tube connector lower end.Three element connects with magnetic.Select and the corresponding screwdriver swing arm of head of screw gauge size earlier during use, the swing arm insertion is connected in the pore with the swing arm head is corresponding, go into size, the corresponding inner hexagon spanner of shape with it in another stomidium interpolation of tube connector again.The rotation inner hexagon spanner, moment reaches swing arm by tube connector, by cutting edge moment is reached head of screw, and screw is tightened or screws out.

The beneficial effects of the utility model are: (1) multiple function collection is an one, and volume is little, and is easy to carry; (2) can easily finish the mounting or dismounting of screw effortlessly; (3) can finish the mounting or dismounting of screw between the two short distance plates.

Fig. 1 is the structural representation of the utility model multifunctional screw driver.Among the figure: 1, interior hexagonal handle, 2, tube connector 3, swing arm.

Fig. 2 is the structure chart of the interior hexagonal handle 1 of this multifunctional screw driver.

Fig. 3 is the cutaway view of this multifunctional screw driver tube connector 2.

Fig. 4 is the structure chart of the cross cutting edge swing arm 3 of this multifunctional screw driver.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

According to shown in Figure 1, when plus screw is installed, select cross cutting edge swing arm 3 earlier with the corresponding cutting edge size of crisscross screw area of bed, cross is changed cutter swing arm 3 inserts with cross and change in the corresponding tube connector of cutter swing arm head 2 holes, again another stomidium interpolation of tube connector 2 go into it size, shape corresponding in hexagonal handle 1.Hexagonal handle 1 in the rotation, moment reaches cross by tube connector 2 and changes cutter swing arm 3, changes edge by cross moment is reached head of screw, and screw is tightened by precession.In like manner, in knockout screw, by same step assembling screwdriver, hexagonal handle in pulling by the direction opposite with tightening screw then can get off screw disassembling.Its connected mode is with tube connector 2 magnetization, then the swing arm head of cross cutting edge swing arm 3 and interior hexagonal handle 1 is inserted respectively in the inner hexagonal hole corresponding with hole dimension in tube connector 2 two ends, by magnetic three elements is linked together.
