It is internal in shape cutter head groove to be provided with driver bit and alignment pin, the head of the front end of driver bit through in circular knife head bore, rear end
Cental axial position has a positioning round orifice, and rear end circular hole, the rear end connection guide of driver bit are inserted in alignment pin front end, before guide rod
End enters in rectangle cutter head groove through regular hexagon guide rod hole, and sleeve inner is additionally provided with spring, and spring is socketed on guide rod and blocked
Between alignment pin stage casing section and sleeve rear end face；
Handle inner is provided with tape measure.
The present invention other be further characterized in that,
Alignment pin is rotary body, and stage casing diameter is big, and rear and front end diameter is smaller and is cylinder, and surface is provided with screw thread.
The diameter of the main body of driver bit is less than the width of rectangle cutter head groove, and the width on head is less than the circular knife head bore
Diameter, the width of remainder is more than the diameter of circular knife head bore.
Guide rod front end is provided with screwed hole.
Alignment pin stage casing diameter is less than the width of rectangle cutter head groove, and front end body diameter is less than the circular hole of driver bit rear end
Diameter, the external screw thread of rear end match with the screwed hole on guide rod.
The diameter of guide rod is less than the diameter of regular hexagon guide rod hole, and the external diameter of spring is more than the diameter of regular hexagon guide rod hole
And it is more than the diameter of guide rod less than the diameter in alignment pin stage casing, spring inside diameter.
The invention has the advantages that by the way that in screw driver handle indoor design tape measure, it is single to add conventional screwdriver
The function of tightening or dismantle screw；The screwdriver head is convertible to be applicable a variety of screws by designing multiple cutter heads simultaneously,
The driver bit of different size can very easily be changed to install or remove corresponding screw, therefore be applicable convenient, can be carried
High workload efficiency.

Fig. 2 is a kind of profile of the outer barrel of multifunctional screw driver of the present invention；
Fig. 3 is a kind of handle portion profile of multifunctional screw driver of the present invention.
In figure, 1. driver bits, 2. alignment pins, 3. springs, 4. sleeves, 4-1. rectangle cutter head grooves, 4-2. circular knife head bore,
4-3. regular hexagon guide rod holes, 5. guide rods, 6. handles, 7. tape measures.
Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
The profile of a kind of multifunctional screw driver structure overall structure diagram disclosed in this invention and outer barrel is shown in respectively
Shown in Fig. 1 and Fig. 2, the main body of driver bit 1 is cylinder, and front end is the head to match with screw, and backend center axis have individual
Positioning round orifice, the head of driver bit 1 can be yi word pattern, cross, six prismatics and large, medium and small different sizes, to adapt to difference
The screw of specification.Alignment pin 2 is rotary body, and mid diameter is larger, and rear and front end diameter is smaller and is cylinder, and surface is set
There is screw thread, sleeve 4 is cylinder, and leading portion is provided with a rectangle cutter head groove 4-1 intersected with periphery, and it is circular that front end axle center is provided with one
Cutter head hole 4-2, rear end axle center are provided with a regular hexagon guide rod hole 4-3, and handle 6 passes through the branch sleeve 4 of a positive six prismsby guide rod 5；
As shown in figure 3, tape measure 7 is installed inside handle 6.The diameter of driver bit 1 is less than cutter head groove 4-1 width, the width on head
Less than cutter head hole 4-2 diameter, the width of remainder is more than cutter head hole 4-2 diameter, and the stage casing diameter of alignment pin 2 is less than cutter head
Groove 4-1 width, the stage casing diameter of alignment pin 2, the internal diameter of spring 3 are more than the external diameter of guide rod 5.Tape measure 7 is located in the handle 6 of screwdriver
Portion, it is extracted out from handle 6 during use.
Driver bit 1 is arranged in cutter head groove 4-1, and leading head passes through circular knife head bore 4-2, and alignment pin 2 is put into cutter head
Groove 4-1, front end are inserted in the circular hole of the rear end of driver bit 1, and rear end is screwed into the screwed hole of guide rod 5, and guide rod 5 passes through regular hexagon guide rod
Hole 4-3, front end enter cutter head groove 4-1, and the spring 3 in sleeve 4 is enclosed on guide rod 5, and be stuck in the stage casing section of alignment pin 2 with
