Abstract

The invention discloses a screw driver. The screw driver comprises a connecting cylinder, a connecting shaft is arranged in the connecting cylinder in the axial direction, three annular grooves arranged side by side are machined in the connecting cylinder and around the connecting shaft, the two opposite groove faces of each annular groove are provided with two layers of magnet sheets respectively, and each annular groove is internally provided with a rotary screw driver body. Each screw driver body is composed of a top part, a rod part and a head part, wherein a regular hexagon magnet block is embedded in the rod part, and the upper end of the head part is connected with a regular hexagon inserting head corresponding to the regular hexagon magnet block in a welding mode. The screw driver has the advantages that the structure is simple, operation is easy, the head parts are replaced conveniently, labor is saved, stability is good, the strength of mounting and dismounting is appropriate, and the damaged screw driver bodies can be replaced in time.

Description

A kind of screwdriver

Technical field

The present invention relates to a kind of screwdriver.

Background technology

Screwdriver is that a kind of being used for twists screw with the instrument forcing it in place, usually has a thin sphenocephaly, in the line of rabbet joint that can insert screw cap or recess.Screwdriver is that in family expenses and plant equipment, the indispensable aid of various parts is dismantled in installation and maintenance.

Existing screwdriver is a screwdriver body, in use, tightening of screwdriver body all relies on the strength of hand to provide strength to screwdriver body rod portion with disassembling section, to reach the object of installation or removal, this traditional screwdriver mounting means compares effort, main source of strength is in the dynamics of hand two fingers wherein, the dynamics of thumb and forefinger, during for the screw that installation or removal are more, two fingers meeting Overexertions, cause two to point grain and can produce the senses of discomfort such as pain, and, existing screwdriver body only adopts a screwdriver body, screwdriver body go wrong can not continue use time, there is no replaceable screwdriver body timely, secondly, existing screwdriver body head is fixedly connected with bar portion, screwdriver body entirety can only be thrown away, do not re-use, cause waste after head is damaged, and increases cost.

Summary of the invention

For the problems referred to above of prior art existence, the present invention aims to provide a kind of screwdriver, and this screwdriver structure is simple, is easy to operation, and head is changed convenient, laborsaving, good stability, and installation, dismounting dynamics put in place, can replace the screwdriver body of damage in time.

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

A kind of screwdriver, comprise a connecting cylinder, described connecting cylinder inside arranges a connecting axle vertically, described connecting cylinder is processed with three cannelures arranged side by side around described connecting axle, the groove face that each described cannelure two is relative all arranges one deck flat thin magnet, in each described cannelure, rotating screwdriver body is all set, each described screwdriver body is by top, bar portion and head composition, embed regular hexagon magnet piece in inside, described bar portion, and weld the regular hexagon plug corresponding with described regular hexagon magnet piece in described head upper end.

Further, form regular hexagon notch between bottom described regular hexagon magnet piece and described bar portion bottom port, the degree of depth of described regular hexagon notch is 5 ~ 10mm.

Further, periphery, described bar portion arranges a snare body.

Further, described body is plastic material.

Further, the top of described screwdriver body is set to annular, described screwdriver body by the hanging of the annular at described top on described connecting axle, and on described top bonding one deck buffering spacer.

Further, described connecting axle both ends all arrange end cap.

Principle of the present invention and beneficial effect are: the present invention designs a connecting cylinder, in connecting cylinder, connecting axle is set, connecting axle is processed with 3 cannelures, hanging screwdriver body in each cannelure, each screwdriver body can do 360 ° of rotations in cannelure, the groove face of cannelure all arranges flat thin magnet, in use procedure, one of them screwdriver body is arranged straight down, all the other two screwdriver bodies rotate up 90 °, two screwdriver body directions are contrary, and it is in the same plane, according to lever principle, the centre of the palm of hand is put on connecting cylinder, 5 fingers are positioned at conplane screwdriver body by two and hold, the screwdriver body simultaneously turned straight down installs or removes, the whole strength of hand all drop on connecting cylinder and two be positioned on conplane screwdriver body, drive screwdriver body straight down to rotate simultaneously, laborsaving, and the excessive use greatly reduced thumb and forefinger and the injury caused, hand comfort level is good, secondly, screwdriver body head upper end and bar portion are provided separately, and can hold fixing fast by regular hexagon magnet piece and regular hexagon plug, and it is inner head firmly can be stuck in bar portion by orthohexagonal corner angle design, ensures the intensity of screwdriver body in use procedure, again, the object that the groove face of cannelure arranges flat thin magnet is when screwdriver body rotates to correct position, can directly be fixed in this correct position and not rock, ensure the stability of screwdriver body.
