Abstract
The utility model relates to a sleeve type apparatus used with screw drivers, which is suitable for common screw driver and semi-automatic screw driver. The sleeve type apparatus used with screw drivers can form into an integral forming with the common screw driver and can also form into a separate type with the semi-automatic screw driver. On the utility model is provided with a clamping device, a draught spring and an observation window. The utility model can avoid the accident of injuring hand by the tool bit which is caused by the driver bit gliding out of the screw cap or the screw swaying over and can also improve the work efficiency.
Description
The utility model sleeve shaped device that a kind of and screwdriver is used of touching upon.
Present normal screws cutter and the semi-automatic screwdriver that uses, all be to pinch screw by hand of user, one holds screwdriver handle, rotation when exerting pressure, make screw precession or back-out, because screwdriver and screw are two individualities, be difficult to make the two to remain on the same axis, so usually be that driver bit slides from the head of a nail, or screw skews, make driver bit stab operator's hand, generally speaking, the user is taken place for preventing to hinder the hand accident, can only be with less power and slower speed operation, thus reduced operating efficiency.
The purpose of this utility model provides the sleeve shaped device that a kind of and screwdriver is used, and this device can prevent the horizontal slippage of driver bit and prevent that screw from skewing, and avoids injuring operator's hand, makes screw precession or back-out on perpendicular to the position of workpiece.
The utility model is to realize like this, a sleeve shaped device that is enclosed within on the screwdriver rod, its neck and clamping device guarantee that cutter head and screw are on same axis, between device and the screw driver handle tension spring is housed, driver bit is closely contacted with screw, for ease of observing screw precession or back-out situation, also have watch window on the device.
Characteristics of the present utility model are, driver bit and screw are in sleeve the inside, and screwdriver and screw remain on the same axis, and cutter head slippage and the screw phenomenon that skews can not take place, the user can operate with bigger power and fast speeds, thereby increases work efficiency.
The utility model has following accompanying drawing:
Vertical complete section front view of the device part that accompanying drawing 1 is and the normal screws cutter fits together.
Accompanying drawing 2 is the vertical complete section front view of operation principle that the normal screws cutter of this device is housed.
Accompanying drawing 3 is the outward appearance front view of device.

Accompanying drawing 13 is the front view of ［ 7 ］.M2：1
Accompanying drawing 14 is the left view of ［ 7 ］.M2：1
Wherein ［ 1 ］ is screwdriver, ［ 2 ］ be tension spring, ［ 3 ］ be sleeve, ［ 4 ］ are watch windows, and ［ 5 ］ are gripper brackets, ［ 6 ］ be holder handle, ［ 7 ］ be the clamper connecting rod, ［ 8 ］ are angle bar clevis plates, and ［ 9 ］ are the riveted joint tenons of connecting rod ［ 7 ］ and handle ［ 6 ］, ［ 10 ］ be back-moving spring, ［ 11 ］ are screws.
Embodiment of the present utility model is the normal screws cutter of 100 millimeters specifications, does specifying below in conjunction with accompanying drawing.
The available 1-2 millimeter of sleeve ［ 3 ］ steel plate processes the rectangular opening of watch window and clamper part earlier, is rolled into tubular then, and mold pressing goes out neck, also available sheet steel pipe processing, inboard and the screwdriver rod contact portion of neck, requiring it is coaxial being slidingly matched, neck outside thread cutting shape groove.Cylinder internal diameter will be a bit larger tham the wideest part of driver bit, also can take the circumstances into consideration to strengthen according to concrete working condition.
The top of tension spring ［ 2 ］ is the neck that is enclosed within screwdriver of pine, can it can be rotated relatively with screwdriver referring to accompanying drawing 1.2, does not come off again, and the middle part is being enclosed within on the screwdriver rod of pine, and the bottom lock ring is in the neck thread shape groove of sleeve ［ 3 ］.
Clamper is made up of support ［ 5 ］, handle ［ 6 ］, connecting rod ［ 7 ］, angle bar clevis plate ［ 8 ］, back-moving spring ［ 10 ］ etc., support ［ 5 ］ curves Contraband shape with 2 millimeters steel plates, rectangular opening is opened in the centre, handle ［ 6 ］ is pressed into arc with steel plate, rectangle or shape hole, garden are opened in the centre, connecting rod ［ 7 ］ two ends precast the riveted joint tenon, left part is longer than the rib portion thickness of angle bar ［ 8 ］ slightly, right part is longer than the thickness of handle ［ 6 ］ slightly, the angle of angle bar clevis plate ［ 8 ］ is less than 90 °, greater than 75 °, length and width are can put rectangular opening on the sleeve ［ 3 ］ into for well.
Its erection sequence is, earlier connecting rod ［ 7 ］ and angle bar clevis plate ［ 8 ］ is riveted together, outwards be enclosed within the rectangular opening of support ［ 5 ］ from the lining then, again support ［ 5 ］ as accompanying drawing 8 spot welding or be welded on the cylindrical shell, rivet handle ［ 6 ］ at last.Angle bar clevis plate ［ 8 ］ can not exceed the inwall of sleeve ［ 3 ］, clamper wants symmetrical vertical to install in knife bar and sleeve axis, again the bottom of tension spring ［ 2 ］ and the neck thread shape groove of sleeve ［ 3 ］ are screwed, then knife bar is inserted from bottom to top sleeve ［ 3 ］.Screw driver handle part and the top that packages tension spring ［ 2 ］ are installed again.
Another embodiment is a semi-automatic screwdriver, because this screwdriver can freely be changed various forms of knife bars, so this installs desirable lower pulling force spring section, the retention sleeve part gets final product with using with cover as annex.
