Abstract
The utility model relates to a connection rod device capable of assisting location of a fastening component. The connection rod device comprises a connection rod body and a sliding sleeve, wherein the connection rod body is a polygonal connection rod fixedly connected with the rear end of a sheath; a polygonal inner hole is formed on the front end of the sheath for replacing different varieties of screwdriver heads; a through-hole is formed transversely in a position near the middle segment of the sheath; an elastic pushing component is mounted in the through-hole; a guide hole for allowing the sheath to pass through is formed in the sliding sleeve; a magnetic component with a punched hole is fixed at the front end of the guide hole; and a position limiting groove with a guide bevel surface is formed at the rear end of the guide hole to limit the position of the elastic pushing component in the sheath. Accordingly, the elastic pushing component of the sheath can push the sliding sleeve outwards tightly at any time when the sliding sleeve assists the fastening component with the location operation through a magnetic component, thereby effectively obviating the rotation and sloshing of the connection rod body, reducing noise, and greatly improving the use effect.
Description
Technical field
The utility model relates to a kind of screw fastening device, particularly a kind of extension bar device with auxiliary lock member location.
Background technology
When using screwdriver locking object; generally be to help screw on the other hand; another hand is the rotating operation screwdriver then, but when being in not easy-operating space, regular meeting can't help screw because of hand; feasible application of force rotation screw bottle opener a little; screw just tilts to drop, and perhaps after unscrewing object, screw also regular meeting's disengaging bottle opener drops; the situation of these all inconvenience is perplexing the operator really.In order to improve this situation, many dealers are convenient to the head end of screwdriver, mode with logical magnetic makes it produce the effect of magnetic, to avoid screw to drop, the area that contacts magnetic between the head end of this mode coping screw bottle opener and screw is little, when the application of force was big, therefore the situation that screw still can drop also can't effectively be improved.After have the dealer promptly to design a kind of auxiliary locator that can more firmly adsorb screw, it is No. 92223088 patent case of TaiWan, China application, see also Fig. 1, it is that preceding endoporus at a sliding sleeve 10 sets firmly magnetic element 11, described magnetic element 11 has through hole 111, sliding sleeve 10 inner faces are also established tool prelocalization skewed slot 12 according to the travel position of extension bar 20 and are located skewed slot 13 with the back, the rear end of one extension bar 20 is provided with hexagonal bar section 21, and its front end is provided with tool heads joining hole 22, extension bar 20 is provided with chase 23 and is made as the elastic component 25 that C shape is buckled with cover in addition, after extension bar 20 is assembled in sliding sleeve 10, before sliding sleeve 10 slides onto, location, back skewed slot 12,13 o'clock, the elastic component 25 of C shape button can fasten spacing, with the moving range of restriction sliding sleeve 10.Extension bar 20 is provided with the containing hole 24 of tool steel ball 26 in addition, and sliding sleeve 10 is provided with the circular groove 14 and the inclined-plane 15 of shrinking back for steel ball 26, make when sliding sleeve 10 pushers make the elastic component 25 of C shape button be positioned prelocalization skewed slot 12, steel ball 26 can be aimed at circular groove 14, and steel ball 26 is shunk back, this moment, tool heads 30 can withdraw from replacing.See also Fig. 2, when the elastic component 25 that is pushed into C shape button forward when sliding sleeve 10 is positioned location, back skewed slot 13, tool heads 30 can plug-in card at the head of screw 31, and with the described screw 31 of magnetic element 11 firm absorption, and be convenient to lock the work of establishing.Though described device can firmly adsorb screw 31, and be convenient to lock the work of establishing, but because of sliding sleeve 10 will slippage on extension bar 20, itself be gapped existence between the two, and the elastic component 25 of C shape button is because of needing the space of strain, and when being positioned location, back skewed slot 13, promptly make the elastic component 25 of C shape button and sliding sleeve 10 and 20 of extension bars gappedly to produce, the elastic component 25 that also is C shape button can't keep pushing up pull sliding sleeve 10 and extension bar 20 at any time, so not only the elastic component 25 of C shape button has the noise generation of rocking, and when extension bar 20 is rotated in operation, gap because of sliding sleeve 10 and 20 existence of extension bar, make extension bar 20 in sliding sleeve 10, to produce the situation of rocking, lock the operation of establishing and influence the operator.
In view of this, the utility model designer then is engaged in the research and development and the making experience of relevant industries for many years with it, at the present problem further investigation that faces, through the research of long-term endeavour with study, grind eventually and create a kind of extension bar body that reduces and rotate and to rock situation, and then reach the extension bar device that significantly promotes the auxiliary lock member of having of operational stability location, significantly to improve the scarce fraud of habit formula, this is design aim of the present utility model.
