Abstract
The utility model provides a general wrench head matched with wrench, which comprises a wrench head body, and is characterized in that polygons which have the same specification are arranged on the inner portion or the outer portion of the wrench head body, and positioning lug bosses are arranged on the polygonal wrench bodies with the same specification. The general wrench head has the advantages that the inner portion and the outer portion of the wrench head adopt the polygons in various shapes, which enlarges the use range. The positioning lug bosses are arranged on the inner portion or the outer portion of the wrench head, which not only increases the strength of the wrench head, but also positions a wrench and a nut, and prevents wrench screwing tools from penetrating out or falling off. The two ends of the wrench head can be used by matching with the wrench, and are both used for screwing nuts, wherein one wrench head is suitable for nuts with one specification and two thicknesses. The wrench head is difficult to fall off or move in the use process, and has convenient operation.

The specific embodiment
See Fig. 1 a, b, the inside of spanner 1 is a kind of interior regular hexagon of specification, and the outside also is a kind of outer regular hexagon of specification, and end externally is provided with circular outside fix boss 2.See Fig. 2 a, b, the inside of spanner 1 is a kind of interior regular hexagon of specification, and the outside also is a kind of outer regular hexagon of specification, and circular outside fix boss 2 is arranged on the middle part of spanner 1 outside.See Fig. 3 a, b, the inside of spanner 1 is a kind of interior regular hexagon of specification, and the outside also is a kind of outer regular hexagon of specification, positioning boss 3 in the middle part of inside is provided with circle.See Fig. 4 a, b, positioning boss 3 and outside fix boss 2 in inside and outside being respectively equipped with of spanner 1.Positioning boss 2 and 3 position are defined as end or middle part as required.See Fig. 5 a, b, c, be respectively equipped with positioning boss 3 and outside fix boss 2 the inside and outside of spanner 1, but two ends externally are equipped with outside fix boss 2.
Above-mentioned outside fix boss 2 and interior positioning boss 3 its shapes are according to using needs to determine shape, circle for example shown in Figure 1, regular hexagon as shown in Figure 7, the polygon that polygon that curve as shown in Figure 6 is formed by connecting or curve and straight line are formed by connecting.Boss also can be the polygon that straight line is formed by connecting, or a plurality of discrete discontinuous small boss.
The effect of outside fix boss: the intensity that 1. increases spanner.2. the outside fix boss plays positioning action two kinds, is located at the end of spanner, plays the effect of folk prescription to dowelled spanner, is located at the middle part of spanner, and the both sides spanner of boss can cooperate spanner to use, and plays the effect of two-way dowelled spanner.
The effect of interior positioning boss: the intensity that 1. increases spanner.2. interior positioning boss plays positioning action two kinds, is located at the end of spanner, plays the effect of folk prescription to setscrew nut, be located at the middle part of spanner, the both sides spanner of boss can attaching nut uses, and two ends can the twisting nut, plays the effect of two-way setscrew nut.
The inside and outside cross sectional shape of above-mentioned spanner uses needs to determine according to different spanners, as shown in Figure 1 inside and outside all is regular hexagon, inside as shown in Figure 8 is regular hexagon, the outside is the polygon that curve is formed by connecting, as shown in Figure 6 inside and outside all is the polygon that curve is formed by connecting, and as shown in Figure 7 inside and outside all is the polygon that curve and straight line are formed by connecting, outside as shown in Figure 9 regular hexagon, inside is that two regular hexagons rotate the polygon that 30 degree form, i.e. 12 jiaos of polygons mutually.And can be used in combination mutually, as shown in Figure 5, the both sides cross sectional shape that is positioned at positioning boss 3 is respectively regular hexagon, 12 jiaos of polygons.
Outside or inside at spanner are provided with annular groove 5 (seeing Figure 11) or multiple spot pit 4 (see figure 10)s or a plurality of through hole 6 (seeing Figure 12), during use, cooperate the spanner that has gripping mechanism (Fastener that elastic circlip, elastomer, steel ball and spring are formed) to use, so that the location.Groove 5, pit 4, through hole 6 can be provided with one or more.
At the outside or inner setting-in elasticity Fastener of spanner, the elasticity Fastener of spanner inside is used to tighten screw-nut, and the Fastener of spanner outside is used to tighten the spanner of spanner.The elasticity Fastener has following form: 1, embedded the shooting property jump ring 7 of annular groove that externally is provided with, jump ring 7 cross sections are circular (seeing Figure 13).2, on the spanner wall, get through the hole, embedded the shooting property column 8 of through hole (seeing Figure 14).3, in its outside or internal boss, the Fastener of being made up of steel ball 9 and spring 10 (seeing Figure 15) is installed, the steel ball 9 of internal boss is used for fixing the spanner of spanner outwardly, and the steel ball 9 of exterior boss is used for fixing the screw-nut of institute's twisting inwardly.Circular groove in Figure 13 example can be shapes such as U-shaped, and jump ring is for disconnecting shapes such as shape or U-shaped.Hole in Figure 14 example is through hole or blind hole, is arranged on the periphery or boss of spanner.
The installation quantity of the elastic circlip of setting-in, elastomer Fastener can be for one or more in the aforesaid various spanner, spanner, and the installation quantity of the elasticity Fastener of steel ball and spring can be one or more groups.Elastomeric cross section can be different shapes such as rectangle, circle, ellipse.Elastic circlip can be different shapes such as rectangle, circle, ellipse, can or disconnect shape for whole shape.
See Figure 16, setting-in magnetic 11 in each periphery of spanner or boss, magnetic 11 is different shapes such as rectangle, circle, magnetic material is the setting-in polylith as required.Magnetic 11 can be cast directly in the spanner the inside or for connecting shape, also can embed in the spanner by the later stage machining process.Various in addition spanners also can adopt magnetic material to make.
See Figure 17, aforesaid various spanners, its periphery can be for disconnecting shape.Gap can be on periphery, and gap also can be on the angle.In addition, spanner is can the damaged or a plurality of peripheries of periphery damaged.
The cooperation spanner using method that the utility model provides:
One of method is attached to spanner on the nut or the spanner spanner commonly used of packing into is pulled and mouthful gone up (or the spanner with elasticity gripping mechanism is pulled on the mouth), gets final product by twisting spanner dismounting nut then.
Two of method, the spanner that will have magnetic is adsorbed on the nut or spanner is pulled on the mouth, gets final product by twisting spanner dismounting nut then.
According to using method, spanner can independent complete sale, does not match other spanner.During use, spanner is attached to or relies on magnetic to be adsorbed on the nut, and spanner moves with nut.Therefore the user buys spanner cooperation one cover spanner use separately, brings into play the function of one or more sets spanners.
One cover spanner also can with one or many spanner systems selling, during use, spanner relies on magnetic to adsorb or elasticity is clamped on pulling on the mouth of spanner, does not need to buy separately the function that other spanners just can be brought into play one or more sets spanners.
