The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
The present invention mainly comprises driver bit 1, protective sleeve 2, dop 3, loop bar 4, toggle 5, packing ring 6.
As shown in Figure 1 and Figure 2, the screw blade comprises protective sleeve 2, dop 3, loop bar 4 and toggle 5.Toggle 5 adopts plastic cement material, and outer wall is circular, and inwall is a hexagon, can hold loop bar 4 and insert wherein and with it inserting one.Loop bar 4 adopts metal material, has certain wall thickness and frictional force, and inside and outside wall is all hexagon.Dop 3 inwalls are that hexagon and front end block loop bar 4 to inner process, and outer wall is that circle and coefficient of friction are bigger, is fixed by the space that the inserting mode is inserted between toggle 5 and the loop bar 4.
As shown in Figure 3, Figure 4, driver bit 1 is divided into rear end and front end two parts, and the rear end is a handle of a knife, and hollow and inwall are circular, and outer wall is a hexagon, can a plurality of driver bits of nestable combination by hollow space.The front end of driver bit 1 is a working portion, can make different forms, a word that differs as size dimension or plum blossom etc.This fore-end of work cutter head stretches out the screw blade, and this part of all the other inoperative cutter heads then can be nestable in the hollow space of adjacent handle of a knife.
As shown in Figure 5, driver bit 1 forms a whole by the mode that stacks in the loop bar 4 that is stored in the screw blade, and utilizes the magnetic force of dop 3 and frictional resistance to prevent to come off.Protective sleeve 2 provides daily protective effect for driver bit 1.The packing ring 6 of loop bar 4 bottoms can disperse the pressure of driver bit to toggle 5.Driver bit 1 and dop 3 all adopt the ferromagnetism metal material to make.Ferromagnetic driver bit 1 not only can adsorb screw, and can be in the mutual contact of each driver bit under the state of stacking by magnetic effect enhancing, makes a plurality of driver bits become one and is difficult for loose integral body.The ferromagnetism metal dop 3 of inserting between loop bar 4 and toggle 5 can utilize the magnetic effect of 1 of the friction of coarse inwall of the inside jut of front end and self and driver bit to form certain resistance, prevents that driver bit 1 from coming off from the loop bar that stores easily.When screwdriver is in off working state, then mainly form the interval of a sealing by the protective sleeve of front end, prevent losing of driver bit 1.
