Abstract
The utility model discloses a manual tool with a bend structure, the main technical proposal is that the structure of the conventional straight driving head is improved to a driving head structure which is provided with a concave center and the two sides of the concave region are bevels. By the use of the driving head with two bevels, the stop part of the tool noumenon is resisted to the two bevels of the driving head, and so the efficacy of angle positive stops is realized. At the same time, the two bevels of the driving head can be set up to special angles which are adapted to special working environments. When the tool is pulled, the efficacy of special angle rapid orientation can be realized. The utility model is a real utility model with industrial application.
Description
Technical field
The utility model relates to a kind of hand-operated tools, particularly relates to a kind of hand-operated tools with bent angle structure.Specifically, it mainly is that first, second stopper section with tool body fastens on the inclined-plane of driving head, make it to have spacing effect in level of significance component, simultaneously also two inclined-planes of driving head can be set as the required special angle of particular job, make it when pulling, to have the effect of locating rapidly in special angle.
Background technology
The bent angle spanner of generally commonly using, its spanner bandle and driving head are separate type, and utilize an alignment pin that its lever and driving head are articulated combination, make it to use at narrow space or when meeting barrier, have the adjustment effect that can make different angles.
Yet the bent angle spanner that this kind utilizes the bent angle structure to form is during its normality, driving head system becomes a level angle with spanner bandle, so its application of force direction and driving head are in the same way, therefore force arm can be reached the longest, that is active force can act on driving head fully, therefore can pull screw tightening easily.But as because of application of force space difference, for example than small space the time, it can make driving head the variation of different angles.Figure 20 shows that example, wherein be adjusted to 30 when spending when driving head, its application of force direction system is one 30 degree angles with driving head, therefore can produce a vertical stress component and horizontal component, but because of its vertical stress component of executing is an invalid component, so need impose bigger power, can reach the effect of pulling of same level angle.And for example shown in Figure 21, wherein be adjusted to 60 when spending when driving head, its application of force direction system is one 60 degree angles with driving head, thus its invalid vertical stress component of executing more than the driving head angle be 30 when spending for big, so need impose the effect of pulling that bigger power just can reach its level angle.Know by inference by above-mentioned, when driving head is adjusted to vertical 90 when spending (shown in Figure 22), the only surplus invalid vertical stress component of its power of executing, thus can produce can't the turn spanner situation.Yet, this kind commonly used the bent angle spanner structure, though can adjust the driving head angle because of different usage spaces, but also can be because of using accidentally, and cause the driving head angle to change over an invalid component plumbness, and the driving head that needs to curve vertical configuration in addition takes out, and row is adjusted to required level of significance component angle again.
Again, this kind bent angle structure applications is on the clamp hand-held tool time, when (as shown in figure 23) wherein clamp shank and sandwich part system is a horizontal normality shape, its force arm maximum, so can easily clamp be pulled engagement, and when clamp shank and sandwich part are vertical configuration, because of its power of executing only is an invalid vertical stress component, so clamp can't be pulled engagement (as shown in figure 24).Moreover, required when utilizing special angle as particular job occasion, because of the application of force fulcrum of wrench body and none blocking position limiting structure of driving head, so when pulling the application of force, driving head can produce the shortcoming that an angle displacement rocks because of a fulcrum;
For improving this shortcoming, just derive as No. the 234966th, Taiwan patent announcement " the spanner positioner of shaking the head of no node locating ", this installs it mainly is to utilize half a circular-arc location edge and a steel ball to fasten the angle of potential head portion pivoted body.But this kind structure is a shiny surface because of its head pivoted body, and can't reach the effect of definite fixed angle.So again just like No. 368922 " improvement of ratchet spanner angular adjustment apparatus " location structure of Taiwan patent announcement, it mainly is with above-mentioned shiny surface driving head, the positioning bead groove that is pivoted is against in the pivot groove of location steel ball card, and reaches the effect of definite fixed drive brilliance degree.Yet this structure is as using when the narrow space, also can be, and then force steel ball to break away from the positioning bead groove because of the narrow and small depression bar that can touch on the spanner in space, and make spanner change over as shown in Figure 8 the invalid vertical stress component shape of 90 degree.This moment, spanner was an invalid vertical stress component because of its power of executing, so spanner can't be pulled.Hence one can see that, commonly uses the fixed angle structure for above-mentioned two kinds, though have the effect of fixed angle, it also can't be effectively spacing in the horizontal component angle with driving head.
In order to solve the defective of existing spanner, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but does not see always that for a long time suitable design finished by development, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that above-mentioned existing spanner exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, pull in the hope of the instrument hand of founding a kind of new structure, can improve general existing on the market conventional spanner structure, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.
The utility model content
