Description

Integrated multi-purpose screwdriver

Technical field

The present invention relates to a kind of integration multi-purpose screwdriver.

Background technology

Screwdriver be a kind of for twisting screw to force its instrument in place, generally have a thin sphenocephaly, can insert Enter in the line of rabbet joint or the recess of screw cap.Screwdriver is that in domestic and plant equipment, the various parts of installation and maintenance dismounting are indispensable Few aid.

Existing screwdriver is a screwdriver body, and in use, tightening of screwdriver body is equal with disassembling section The strength relying on hand provides strength to screwdriver body bar portion, to reach the purpose of installation or removal, this traditional screwdriver Mounting means is relatively elaborate, main source of strength in the dynamics of hand two fingers therein, the dynamics of thumb and forefinger, During for installing or removing more screw, two fingers meeting Overexertions, lead to two finger grains can produce pain etc. no Suitable sense, and, existing screwdriver body only with a screwdriver body, screwdriver body go wrong can not be continuing with when, There is no timely replaceable screwdriver body；Secondly, existing screwdriver body head is fixedly connected with bar portion, after head is damaged Screwdriver body integrally can only be thrown away, not use, cause to waste, and increase cost；Again, existing screwdriver body only has One head, and conventional screwdriver body head have several, only with a kind of inapplicable bigger range of head design, The scope of application is restricted, and not only only using a screwdriver during actual installing/dismounting, needs multiple spiral shells Silk knife is used in combination, and existing single screwdriver design can not meet multiplex function.

Content of the invention

The problems referred to above existing for prior art, the present invention is intended to provide a kind of integration multi-purpose screwdriver, this screw Knife structure is simple, and it is easy to operation, it is convenient that head is changed, laborsaving, good stability, installs, dismounting dynamics puts in place, can replace damage in time Bad screwdriver body, and applied widely, multi-functional, multiplex.

To achieve these goals, the technical solution adopted in the present invention is as follows:

Integrated multi-purpose screwdriver, including a connecting cylinder, described connecting cylinder axially inside arranges a connecting shaft, described It is machined with four cannelures arranged side by side around described connecting shaft on connecting cylinder, the relative groove face of each described cannelure two is all provided with Put one layer of flat thin magnet, in each described cannelure, set gradually rotatable screwdriver body one, screwdriver body two, screwdriver body three And screwdriver body four, described screwdriver body one, screwdriver body two, screwdriver body three and screwdriver body four all include top and Bar portion, is internally embedded regular hexagon magnet piece in described bar portion.

Further, described screwdriver body one also includes cross head, and described screwdriver body two also includes manifold portion, described Screwdriver body three also includes Flos Mume head, and described screwdriver body four also includes hexagon socket head portion.

Further, described cross head, manifold portion, Flos Mume head and hexagon socket head portion upper end all weld with described just The corresponding regular hexagon plug of hexagon magnet piece.

Further, form regular hexagon notch between described regular hexagon magnet piece bottom and described bar portion bottom port, The depth of described regular hexagon notch is 5 ~ 9mm.

Further, outside described screwdriver body one, screwdriver body two, screwdriver body three and bar portion described in screwdriver body four It is respectively provided with a snare body on week, and described body adopts plastic material.

Further, described screwdriver body one, the top of screwdriver body two, screwdriver body three and screwdriver body four are set to Annular, described screwdriver body is hung in described connecting shaft by the annular at described top, and a layer of bonding on described top Buffering spacer.

Further, described connecting shaft both ends are respectively provided with end cap.

The invention has the beneficial effects as follows: the present invention designs setting connecting shaft in a connecting cylinder, connecting cylinder, and connecting shaft is processed There are 4 cannelures, hanging screwdriver body one, screwdriver body two, screwdriver body three, screwdriver body four in each cannelure, four Described screwdriver body represents four kinds of conventional screwdriver bodies: cross, a word, Flos Mume and interior hexagonal, arranges four kinds of different spiral shells Silk cutter hub can expand its scope of application so as to possess the function of multi-functional, multiplex and convenient operation, four screwdriver bodies can be in ring Do 360 ° of rotations in shape groove, flat thin magnet is respectively provided with the groove face of cannelure, during use, one of screwdriver body is erected Directly down-set, its excess-three screwdriver body rotates up 90 °, and in three screwdriver bodies, both direction is identical, another and this Both direction identical screwdriver body in opposite direction, and but three be respectively positioned on same plane, according to lever principle, hand The centre of the palm is put on connecting cylinder, and the screwdriver body that three are generally aligned in the same plane is held by 5 fingers, turns spiral shell straight down simultaneously Silk cutter hub is installed or removed, and the whole strength of hand all falls within connecting cylinder and three screwdriver bodies being generally aligned in the same plane On, drive screwdriver body straight down to rotate simultaneously, laborsaving, and greatly reduce the excessive use to thumb and forefinger And the injury causing, hand comfort level is good；Secondly, four screwdriver body head upper ends and bar portion are provided separately, and pass through positive six Side shape magnet piece and regular hexagon plug quickly can hold fixation, and can be by head by orthohexagonal corner angle design Firmly be stuck in bar portion internal it is ensured that during using screwdriver body intensity；Again, Magnet is arranged on the groove face of cannelure The purpose of piece is when screwdriver body rotates to correct position, can directly be fixed in this correct position and do not rock it is ensured that The stability of screwdriver body.
