Description
Technical field
The present invention relates to a kind of screwdriver, especially can change head to adapt to the hand screwdriver of dissimilar screw.
Background technology
Screwdriver is a kind of commonly used instrument, and currently used is the most extensively fixed, and a kind of screwdriver can only install or remove a kind of screw.When maintenance is with the equipment of plurality of specifications screw, generally require the screwdriver getting out various dimension in advance, thus not very convenient, affect work efficiency.
Summary of the invention
The problem existed for currently used screwdriver, the present invention devises a kind of head-exchangeable screwdriver, and the scheme taked is:
This screwdriver is by driver bit, alignment pin, spring, sleeve and handle composition, driver bit main body is four-prism, front end is the head matched with screw, back-end central shaft position has a positioning round orifice, alignment pin is rotary body, stage casing diameter is big, front and back two sections of diameters are little, leading portion is cylindrical, back segment is also cylindrical and is provided with external screw thread, sleeve configuration is cylindrical, the rectangle cutter head groove intersected with periphery is had on leading portion barrel, barrel forward end axle center is provided with a circular knife head bore, axle center, its rear end is provided with a regular hexagon guide rod hole, handle front end is positive six prism guide rods, axle center, guide rod front end is provided with screwed hole, handle end is handle；The width of the main body four-prism of driver bit is less than the width of cutter head groove, the width of head is less than the diameter in cutter head hole, the width of remainder is more than the diameter in cutter head hole, alignment pin stage casing diameter is less than the width of cutter head groove, alignment pin nose circle column diameter is less than driver bit rear end positioning round orifice diameter, alignment pin rear end external screw thread mates with handle guide rod screwed hole, guide rod diameter is less than the guide rod hole diameter of sleeve, spring outer diameter is more than the aperture of guide rod hole, and spring inside diameter is more than handle guide rod circumscribed circle diameter and less than alignment pin stage casing diameter；Driver bit and alignment pin are each provided in cutter head groove, the leading head of driver bit passes cutter head hole, the front end of handle guide rod enters in cutter head groove through guide rod hole, the leading portion of alignment pin inserts driver bit rear end positioning round orifice, its rear end is screwed into handle guide rod screwed hole, it is positioned at the spring housing of sleeve on the guide rod of handle, and is connected between alignment pin stage casing end face and sleeve rear end face.
This screwdriver can be changed the driver bit of different size in use very easily and install or remove corresponding screw, the most easy to use, can improve work efficiency.
Accompanying drawing explanation
Fig. 1 is assembly relation schematic diagram of the present invention.
Fig. 2 is middle sleeve semi-section schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention will be further described.
As depicted in figs. 1 and 2, driver bit 1 main body is four-prism, front end is the head matched with screw, back-end central shaft position has a positioning round orifice, the head of driver bit 1 can be the various ways such as yi word pattern, cross, six prismatics and the different size such as large, medium and small, to be applicable to the screw of different size.Alignment pin 2 is rotary body, stage casing diameter is big, and front and back two sections of diameters are little, and leading portion is cylindrical, back segment is also cylindrical and is provided with external screw thread, sleeve 4 profile is cylindrical, and leading portion is provided with a rectangle cutter head groove 41 intersected with periphery, and axle center, front end is provided with a circular knife head bore 42, axle center, rear end is provided with a regular hexagon guide rod hole 43, handle 5 front end is positive six prism guide rods, and guide rod end axle center is provided with screwed hole, and handle 5 rear end is handle.The width of the main body four-prism of driver bit 1 is less than the width of cutter head groove 41, the width of head is less than the diameter in cutter head hole 42, the width of remainder is more than the diameter in cutter head hole 42, alignment pin 2 stage casing diameter is less than the width of cutter head groove 41, alignment pin 2 nose circle column diameter is less than driver bit 1 rear end positioning round orifice diameter, alignment pin 2 rear end external screw thread mates with handle 5 guide rod screwed hole, guide rod diameter is less than sleeve 4 guide rod hole 43 diameter, spring 3 external diameter is more than the aperture of guide rod hole 43 and less than alignment pin 2 stage casing diameter, spring 3 internal diameter is more than handle 5 guide rod circumscribed circle diameter.Driver bit 1 is arranged in cutter head groove 41, leading head passes cutter head hole 42, alignment pin 2 is put in cutter head groove 41, driver bit 1 rear end positioning round orifice is inserted in front end, rear end is screwed into handle 5 guide rod screwed hole, and handle 5 guide rod passes guide rod hole 43, and front end enters in cutter head groove 41, the spring 3 being positioned at sleeve 4 is enclosed within the guide rod of handle 5, and is connected between alignment pin 2 stage casing end face and sleeve 4 rear end face.
When changing driver bit 1, first handle 5 is pulled back, make the leading portion cylinder of alignment pin 2 deviate from from the positioning round orifice of driver bit 1 rear end, then driver bit 1 rear end is pulled out from cutter head groove 41, being extracted out from cutter head hole 42 by driver bit 1 head, so far, original driver bit 1 has taken off again.When other specification driver bits 1 are installed, first handle 5 is pulled back, again driver bit 1 head is inserted in cutter head hole 42, then driver bit 1 rear end is pressed into cutter head groove 41, last release handle 5, under the elastic force effect of spring 3, the leading portion cylinder of alignment pin 2 inserts in the positioning round orifice of driver bit 1 rear end, installs.
