Abstract
The invention relates to a socket spanner comprising a shell, a shaft II and a worm gear. The shaft II and the worm gear are rotatably disposed in the shell. A worm is arranged at the bottom of the shaft II, and is mutually meshed with the worm gear. A socket penetrates the shell to be fixed on the worm gear, and the axis of the socket mutually coincides with that of the worm gear. During use, the head end of the shaft II is clamped by a chuck of a piston drill, the socket is axially sleeved on a nut or a bolt head, a switch of the piston drill is pressed to drive the shaft II to rotate, the worm gear is driven to rotate by the worm, and the socket is driven to rotate to have the nut or the bolt head removed or screwed tightly. Due to the fact that the worm gear is meshed with the worm and the axis of the shaft II is mutually vertical to that of the socket, operation comfortableness and work efficiency are improved, and the problems that an open spanner is easy to slip and causes damage to the nut are solved.
Description
Technical field
The present invention relates to a kind of hardware ﹠ tools, be specifically related to a kind of box spanner.
Background technology
In the sleeve barrel tool of using at present, the axial sleeve spanner is commonly used, and do not have at present from the box spanner that axially becomes vertical direction, but in the auto repair process, there is certain problem that does not have the operating space in the axial sleeve spanner.Because automobile manufacturing process is to hang in the engine nacelle after the engine final assembly is good to install and fix, and be to repair with regard to the car formula during maintenance, can not hang out the cabin to engine to keep in repair that only rebuilding an engine to hang out the cabin.Nowadays above very compact narrow, the limited space of its engine nacelle parts of automobile of medium and high classes, it is very difficult to disassemble bolt.Handle jacket, the dismounting of open-end wrench double offset ring spanner instrument are used at present auto repair substantially, and the disassembly process spanner needs continuously alternately, and the translation-angle low-angle repeats rotation and disassembles the loading and unloading bolt.If the operation under the obstacle is arranged, increase especially operation easier under plumbness.
Summary of the invention
The present invention is in order to overcome the deficiency of above technology, provide a kind of can be from axially becoming the box spanner of vertical direction.
The present invention overcomes the technical scheme that its technical problem adopts:
This box spanner, comprise that shell, the axle II, the rotation that rotatably are installed in the shell are installed on the worm gear in the shell, the bottom of described axle II is provided with worm screw, and described worm and wheel is intermeshing, sleeve passes shell and is fixed on the worm gear, and the axis of the axis of sleeve and worm gear overlaps.
Can change angle by any direction when realizing dismounting, also comprise the axle I, described axle I is connected and fixed by universal drive shaft and axle II.
The invention has the beneficial effects as follows: the head end of during use the chuck of power drill being clamped the axle II, afterwards sleeve is set on nut or the bolt head vertically, press afterwards the switch of power drill, its driving shaft II is rotated, thereby the axle II is rotated and is relied on the worm drive worm gear to rotate, and screws thereby make the sleeve rotation make it with nut or bolt head dismounting or install.Because the engagement of worm gear and worm screw makes the axis of axle II mutually vertical with the axis of sleeve, therefore by changing angle, so that get final product operation in the hand-held situation of power drill perpendicular to bolt or nut axis.Namely improve the comfortableness of operation, improved operating efficiency, solved again the problem of utilizing the easy slippage of open-end wrench and damaging nut.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure, 1. axle I 2. universal drive shafts 3. axle II 4. shells 5. worm gears 6. sleeves 7. worm screws.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing 1.
This box spanner, comprise that shell 4, the axle II 3, the rotation that rotatably are installed in the shell 4 are installed on the worm gear 5 in the shell 4, the bottom of described axle II 3 is provided with worm screw 7, described worm screw 7 is intermeshing with worm gear 5, sleeve 6 passes shell 4 and is fixed on the worm gear 5, and the axis of the axis of sleeve 6 and worm gear 5 overlaps.During use the chuck of power drill is clamped the head end of axle II 3, afterwards sleeve 6 is set on nut or the bolt head vertically, press afterwards the switch of power drill, its driving shaft II 3 is rotated, thereby axle II 3 is rotated and is relied on worm screw 7 to drive worm gear 5 rotations, screws thereby make sleeve 6 rotations make it with nut or bolt head dismounting or install.Because the engagement of worm gear 5 and worm screw 7 makes the axis of axle II 3 mutually vertical with the axis of sleeve 6, therefore by changing angle, so that get final product operation in the hand-held situation of power drill perpendicular to bolt or nut axis.Namely improve the comfortableness of operation, improved operating efficiency, solved again the problem of utilizing the easy slippage of open-end wrench and damaging nut.
Can also comprise axle I 1, described axle I 1 is connected and fixed by universal drive shaft 2 and axle II 3.Power drill is clamped axle I 1, because universal drive shaft 2 has the effect of arbitrarily angled transmission driving torque, the direction of therefore hand-held power drill can tilt arbitrarily, with operation in the narrow and small crowded space of better use enging cabin during use.
Claims (2)
1. box spanner, it is characterized in that: comprise that shell (4), the axle II (3), the rotation that rotatably are installed in the shell (4) are installed on the worm gear (5) in the shell (4), the bottom of described axle II (3) is provided with worm screw (7), described worm screw (7) is intermeshing with worm gear (5), sleeve (6) passes shell (4) and is fixed on the worm gear (5), and the axis of the axis of sleeve (6) and worm gear (5) overlaps.
