Abstract
The invention relates to a hand tool, in particular to a nail-holding magnetic head screwdriver. The problem that an existing magnetic head screwdriver cannot absorb and hold copper and aluminum screws and cannot absorb and hold iron screws regularly is solved. The nail-holding magnetic head screwdriver comprises a magnetic head screwdriver body, the magnetic head screwdriver body is provided with a nail-holding device, and the nail-holding device is formed by a guide ring annularly sleeving a cone rod of the magnetic head screwdriver body and a rope sleeve fixedly adhering to the guide ring and having the length larger than that of the guide ring. The guide ring and the rope sleeve are made of elastic materials. The nail-holding magnetic head screwdriver has the advantages that the screws are held reliably, installed and positioned accurately and absorbed conveniently after being dismantled, and the nail-holding magnetic head screwdriver is suitable for installation and dismantling of the screws at the sunken positions.
Description
Technical field
The present invention relates to hand-held tool, be specially and hold nail magnetic head screwdriver.
Background technology
The screw installation position of electric product is equipped with two classes: highlight with depression.The screw of recessed position, is difficult for recognizing position during dress; While unloading, inconvenience captures.People, before this by crewdriver attachment magnetization, utilize the ferromagnetism of iron screw, hold screw and load and unload.In recent years on this basis, on crewdriver attachment, apply magnetosphere, develop magnetic head screwdriver, greatly facilitate the handling of recessed position screw; But still have can not sticking copper aluminium screw and sticking not just, can not the exist together shortcoming of a line of screwdriver axis and screw axis.
Summary of the invention
The present invention solves existing magnetic head screwdriver can not sticking copper aluminium screw and to the not positive problem of iron screw sticking, and a kind of nail magnetic head screwdriver of holding is provided.
The present invention adopts following technical scheme to realize: hold nail magnetic head screwdriver, comprise magnetic head screwdriver body, on magnetic head screwdriver body, be provided with nail holding device, described nail holding device is by being located on the duct ring on magnetic head screwdriver body cone bar and adhering on duct ring and noose that length is greater than duct ring length forms.Described duct ring and noose are made with elastomeric material.
Duct ring is embraced on magnetic head screwdriver body cone bar by tangential elastic force, can slide along cone bar, and can be fixed on the optional position of cone bar.Noose is bonded on duct ring, can slide with duct ring.During use, cartridge screw: push duct ring to crewdriver attachment together with noose, and make noose appropriateness exceed crewdriver attachment end face.Then wanting cartridge screw head, strut and insert noose, also will make flat recess or the cross recess of crewdriver attachment alignment screw.Flexible because of noose, not only can grip head of screw; And can make head of screw axis concentric with screwdriver rod axis, guarantee that screw is recognized position accurately rapid.Then just rotatable screwdriver handle, is screwed into nail hole by screw.Regain screwdriver, binding is complete.Because noose is held screwdriver bar tightly through duct ring, and the obvolvent section of noose and crewdriver attachment much larger than noose the obvolvent length to head of screw, therefore head of screw can be deviate from noose smoothly; Can there is not the situation that noose is pulled away screwdriver bar.Unload screw: duct ring is motionless with youngster together with the standing screwdriver handle of noose.Make screwdriver remove to unload screw.After unloading, by crewdriver attachment magnetic force, draw.
The beneficial effect of holding nail magnetic head screwdriver is: reliable to screw gripping, and install and recognize position accurately, unload rear absorption conveniently, be suitable for the handling of recessed position screw.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-bores bar, 2-duct ring, 3-noose.
The specific embodiment
Hold nail magnetic head screwdriver, comprise magnetic head screwdriver body, on magnetic head screwdriver body, be provided with nail holding device, described nail holding device is by being located on the duct ring 2 on magnetic head screwdriver body cone bar 1 and adhering on duct ring 2 and noose 3 that length is greater than duct ring length forms.During concrete manufacture, duct ring 2 is through on screwdriver bar 1 along manifold screwdriver flat horizontal surface; Or be through without leave on crosshead screwdriver bar 1.Then noose 3 is bonded on the duct ring 2 being loaded on screwdriver bar 1.The high-elastic plastics manufacture of duct ring 2 use; High 10mm; Before dress, internal diameter is less than cone bar (1) diameter; Skin depth 2mm; There is an axial slit.Noose 3 use high-elasticity latexes are manufactured.Length equals high, the head of screw long sum long with magnetic head screwdriver body conehead of duct ring 2.Before dress, internal diameter is less than cone bar 1 diameter.Skin depth 1mm.
Claims (3)
1. hold nail magnetic head screwdriver for one kind, comprise magnetic head screwdriver body, it is characterized in that: on magnetic head screwdriver body, be provided with nail holding device, described nail holding device is by being located on the duct ring (2) on magnetic head screwdriver body cone bar (1) and adhering to noose (3) formation that the upper and length of duct ring (2) is greater than duct ring length.
2. the nail magnetic head screwdriver of holding according to claim 1, is characterized in that: high-elastic plastics manufacture for duct ring (2); High 10mm; Before dress, internal diameter is less than cone bar (1) diameter; Skin depth 2mm; There is an axial slit.
3. the nail magnetic head screwdriver of holding according to claim 1 and 2, is characterized in that: noose (3) is used high-elasticity latex manufacture, and length equals high, the head of screw long sum long with magnetic head screwdriver body conehead of duct ring (2); Before dress, internal diameter is less than cone bar (1) diameter, skin depth 1mm.
