Description

Screwdriver

Technical field

The utility model relates to a kind of daily living article, relates in particular to a kind of screwdriver.

Background technology

Screwdriver of the prior art in use all needs palm to be adjacent to handle comprehensively, thereby holding real back turning handle conscientiously drives driver bit and realizes changeing the turn of the screw, because strength is the contact friction conduction of the armrest palm and handle, and do not make things convenient for the radially handle of the application of force, so strength is very limited, when in the face of some screw that becomes rusty solid, be very much hard, on the other hand, the screw of using in the stubborn hole of screw swivel of the prior art also is very inconvenient, because driver bit and knife bar submerge in the hole, knife bar blocks people's sight, make that cutter head can not precisely be located in the process that the handle commentaries on classics is twisted, the one cutter head situation that will come off from the screw notch firmly often appears slightly, need once more the location to screw again, if it is too tight to run into screw, overexert and the not dark situation of hole, screwdriver the situation jumping out hole even hurt sb.'s feelings occurs toward the contact meeting, moreover, the knife bar of screwdriver of the prior art and handle be being fixed together inflexibly all, pack up and the sharp part of cutter head and knife bar can not be hidden, like this screwdriver carry also very inconvenient, put it in pocket or the paper bag, cutter head is poked the pocket bag easily, carries the hidden danger of hurting sb.'s feelings in addition and hindering oneself.

The utility model content

In view of this, technical problem to be solved in the utility model is: it is more sufficient and operation can assist location in big deep holes to provide a kind of commentaries on classics to twist strength, carries the screwdriver that does not also have any potential safety hazard.

In order to achieve the above object, the utility model adopts following technical scheme to realize:

A kind of screwdriver, comprise the cutter head that connects successively from the bottom to top, knife bar, bar handle connector and handle, wherein, described handle inside is provided with the cavity of the described bar handle of downward perforation connector along the axle center periphery, the chamber wall of described cavity is provided with internal thread, the bar wall of described knife bar is provided with external screw thread, described knife bar is solidly connected described bar handle connector and described handle in described cavity by described external screw thread and described internal thread spiral shell, described knife bar is not bolted in the described cavity one section and is bolted with nut, be bonded with sheet on the outer wall of described nut or be socketed with garment bag, the described handle of described cavity periphery vertically symmetry be divided into two handle portions, two corresponding mutually end face peripheries of described handle portion have the adaptive clamping part of detaining card connection each other, be equipped with articulated part on the lower surface of two described handle portions, the upper surface of described bar handle connector is equipped with drive-connecting shaft on the position of corresponding two described articulated parts, two described articulated part correspondences are articulated on the described drive-connecting shaft, two described handle portions are the upper end and have the hollow structure that opening and periphery are with leg, leg is connected on the outer wall of described cavity in the handle of the corresponding described cavity outer wall side of described handle portion, the opening of described handle portion upper end is stamped buckle closure, be equipped with the one or more nuts that are greater than or less than described nut in order to be spirally connected described knife bar and external diameter in the described handle portion, described cutter head is the in-line cutter head that is bolted in described knife bar, also is equipped with the cross cutter head in order to the described knife bar that is spirally connected in the described handle portion.

As preferably, described cutter head, knife bar, nut, articulated part, drive-connecting shaft are stainless steel.

As preferably, described bar handle connector and handle are plastic material.

Compared to existing technology, screwdriver of the present utility model is provided with the nut that external diameter varies in size, selection by these nuts use can make put in that big dark and screwdriver knife bar in the unapproachable hole of staff can be firm by admittedly on the inwall of hole, auxiliary driver bit location, make cutter head once entering the screwing in the groove of screw, no matter firmly much, the phenomenon that sideslip causes driver bit to come off from screw can not appear, increase operating efficiency, simultaneously, the utility model in use, handle portion broken into two with one's hands along drive-connecting shaft be a word shape, can provide for the user of screwdriver and can conduct the horizontal lever that power is twisted in bigger commentaries on classics, a difficult problem and the embarrassment do not used effectively when thoroughly having solved in the face of corrosion screw to a certain degree, moreover, the utility model is also very convenient aspect carrying, people can take off its cutter head in the hollow space that is put in handle portion, screwing knife bar then enters in the cavity of handle, so, cutting edge is hidden, going out, it is safe and convenient to carry, and has practicality and creativeness.
