Abstract

A multifunctional combined spanner has the functions of clamping nuts, threading, loading and unloading screws. A method is that a nut clamping seat fixed to both sides of a handle and the inside and outside of a movable square cog are nested from layer to layer; the method is adopted to change the dimension and the shape of the inner and the outer profiles of both ends of the spanner to apply to clamp various standards of the interior and exterior polygon nuts (or bolts). The nesting of the spanner can be served as the product independently and match the prior fixing spanner to use. The spanner has the feathers of low production cost, broad application, economizing the raw material and convenient carrying and storing.

Description

Multi-function combined spanner

The utility model multifunctional combination wrench relates to hardware ﹠ tools.

The box spanner that uses in the prior art and in four, die nut etc., mostly purposes is single, the corresponding a kind of nut of a kind of spanner had both limited the scope of application, wasted raw material again.Even normally used monkey wrench and Chinese patent literature Int.CL ⁴The B25B13/02 application number is the 85205524 multi-functional double offset ring spanners of announcing, though disclosed the multi-edged of spanner, runs into interior four, hex bolts etc., can only be deeply aware of one's own helplessness when faced with a great task, more can't machining screw and loading and unloading screw.

The purpose of this utility model is to avoid the weak point in the above-mentioned technology, and a kind of inside and outside polygonal nut (or bolt) that is applicable to fastening all size is provided, and can process the multifunctional combination wrench that internal and external threads and double as screwdriver are used.

The purpose of this utility model can reach by following measure:

A kind of multifunctional combination wrench is by handle: nut holder (1); Activity side's tenon (5); The regular polygon of array multilayer different size nested (2), (3), (4); Pull golden box (6); Boosting-rod formations such as (7).

Nut holder (1) is a regular hexagon post in the outer garden, and the hexagon upper end has recessed stupefied, over against handle side's waist one square hole is arranged, and there is a pin-and-hole in the waist other places.

Activity side's tenon (5) is square post, and the lower end is fixed on the handle with axle, can pivot 180 °, and waist has a pair of pinned hole.

Regular polygon nested (2), (3), (4) are open tubular column, positive four, regular hexagon and quincunx three groups are arranged, every group of nested innermost layer is square, outermost layer is regular hexagon, and the nested number of plies is corresponding to the different size of standard nut, and each nested waist has pair pinned hole.

Pull golden box (6) and be regular hexagon post outside the interior garden, outside, upper end and lower end inner edge all have protruding stupefied, and waist has a pin-and-hole and fixedly pulls the screw of golden usefulness.

Boosting-rod (7) left end top is a movable screw cutter holder head, and shaft is a regular hexagon, and it is one protruding stupefied that left end has, and waist has pin-and-hole, and the right-hand member top is fixing square tenon.

Above-mentioned all pin-and-holes can be in alignment with each other when installing and fix with pin.Spanner and accessory thereof use and need with tool steel or other the material manufacturings that can make spanner of high rigidity, overall dimension and configuration design obedience.Nested (2), (3), (4) can be used as product, the existing spanner of cooperation separately.

The utility model compared with prior art has following advantage:

1. applied range, same spanner is applicable to the inside and outside nut (or bolt) of plurality of specifications.

2. widen 3 functions of use, except that clamp nut, can also process internal and external screw thread, and can make screwdriver and use.

3. save material, reduce cost.

4. be easy to carry collection.

The drawing of accompanying drawing is described as follows:

Fig. 1 is multifunctional combination wrench and various annex schematic diagram.

(1) nut holder (2) regular hexagon nested groups

(3) quincunx nested groups (4) square nested groups

(5) movable side's tenon (6) is pulled golden box (7) boosting-rod

Fig. 2 is a multifunctional combination wrench user mode reference diagram.

The utility model will be described in further detail in conjunction with (accompanying drawing) embodiment

As shown in Figure 1, because the outermost outline of nested (2), (3), (4) is a regular hexagon, respectively it successively is bumped in the nut holder (1) on demand, fix with pin, can play and dwindle internal diameter and change interior profile effect, be applicable to the outer regular polygon nut (or bolt) of fastening all size.

As shown in Figure 1, because the interior profile of nested groups innermost layer is square, nested (2), (3), (4) successively are enclosed within on movable side's tenon (5) on demand, with pin insert the pin-and-hole locking, can the side's of increase tenon external diameter and change outer contour shape, be applicable to the inner polygon bolt of fastening all size.

Shown in Fig. 2 (A), the golden clothes of pulling of different size are advanced to pull in the golden box (6) and fix with screw, in the inserted num holder (1) the recessed stupefied line each other of the protruding stupefied and nut holder of pulling golden box is closed simultaneously again, lock from pin-and-hole with pin again, the square tenon on boosting-rod (7) top is inserted in the square hole of nut holder (1) waist, afterburning rotation can threading.

Shown in Fig. 2 (B), the screw tap bolt die is sandwiched in the movable screw cutter holder head of boosting-rod, be inserted in together in the nut holder (1), make the recessed stupefied line on the protruding stupefied and nut holder (1) on the boosting-rod (7) share the pin locking, afterburning rotation can machining internal thread.

As shown in the figure, boosting-rod (7) self can be made the screwdriver flexible handle, sandwiches different screwdrivers, can load and unload screw.

As shown in Figure 2, activity side's tenon (5) is rotated to parallel, rotate boosting-rod (7) and can load and unload short-legged inner polygon bolt with handle.
