Description
Technical field
The present invention relates to a kind of die nut, espespecially a kind of hexagonal bulb spanner.
Background technology
With reference to Figure 19, be a kind of schematic diagram of existing die nut.Spanner 9 one ends form ball head 91, and in adjoining ball head 91 interior lateral circle surfaces formation one ring necks 92, wherein ball head 91 peripheral rings are established and are formed a hex surface 93, and inwardly be provided with a storage tank 94 in hex surface 93 more than one of them, the notch of this storage tank 94 is slightly less than the groove body, and outwards sequentially is provided with a spring 95 and an inboard is subjected to spring 95 pushing tows and the outside to expose the little steel ball 96 of storage tank 94 in interior; Utilize little steel ball 96 structure that the surface is round and smooth and but elasticity is advanced to push away, when utilizing ball head 91 oblique cuttings to enter the hexagon ring of spiral lock, effect with convenient turnover, and because little steel ball 96 can be filled up hexagon ring because using the space of wearing and tearing, making when rotating can be more laborsaving and be difficult for making the hexagon ring wearing and tearing.
Aforementioned patent relies on spring and little steel ball top to be located at hexagon ring, reaches the purpose that ball head can be engaged in hexagon ring.Such design must be processed a storage tank at the hex surface of ball head, and spring and little steel ball are assembled in the storage tank.Compared to traditional hexagonal bulb spanner, many processing storage tanks, prepare the program of spring and little steel ball and assembling.Therefore, such design has cost increases and the slow disappearance of process velocity.
Moreover, this design that utilizes spring and little steel ball top to be located at hexagon ring, really do not improve the problem of skidding of hex surface and hexagon ring, die nut only is provided with single group of spring and little steel ball, therefore only can provide single mask to have better top to establish effect, the top of little steel ball is established and can't be solved the disappearance of skidding fully.
And little steel ball pushes up in the mode of a contact and is located at hexagon ring, and when die nut was used in special angle and favours hexagon ring, little steel ball very likely can break away from hexagon ring, establishes hexagon ring and make little steel ball push up.
Because the disappearance of above-mentioned existing structure, the inventor invents out a kind of hexagonal bulb spanner, and it can overcome all shortcomings of above-mentioned existing structure.
Summary of the invention
Wish of the present invention solves the disappearance that background technology exists, and provides a kind of hexagonal bulb spanner can solve the disappearance of prior art.
For achieving the above object, the technical solution used in the present invention is:
A kind of hexagonal bulb spanner, the one end forms a bulb end, this bulb end can drive to be driven, this bulb end has a virtual work section, this virtual work section can contact with to be driven, this bulb end comprises first cambered surface, this first cambered surface be shaped at least one recess and at least one bite, this recess is adjacent with this bite, this bite and this virtual work section are coplanar, this recess is recess compared to this virtual work section, and this bite can increase the frictional force between this bulb end and to be driven.
This recess and this bite directly are integrally formed in this bulb end.
This bulb end is provided with a maximum outside diameter, and this recess is by this maximum outside diameter, and this recess can provide to be driven of the vertical driving of this bulb end with this maximum outside diameter joint.
This first cambered surface several recesses that are shaped, the distance between this each recess are not to equate.
This recess and this bite are and are arranged in parallel.
This first cambered surface comprises a first end and second end, this recess is strip, the two ends of this recess are respectively towards the first end of this first cambered surface and the second end of this first cambered surface, and the length that this recess extends is proportional with the angle of relative to be driven the swing of this bulb end.
This first cambered surface comprises a first end, second end, first side and second side, this recess is oblique line shape, be the end of recess of oblique line shape towards first end and the first side joint of this first cambered surface, be the other end of recess of oblique line shape towards the second end and the second side joint of this first cambered surface.
This recess is staggered oblique line shape.
This recess is point-like.
The rounded recess of this recess.
Compared with prior art, the beneficial effect that has of the present invention is:
When the present invention relies on the bulb end that rotates this hexagonal bulb spanner, because two contact-making surfaces of bite force in drive hole, and can reach the effect of better interlock.This recess can increase this bite and drive hole contact-making surface quantity and improve the problem of skidding.
The present invention relies on this recess and bite and increases the quantity of contact-making surface, this recess and bite can be processed directly and be finished, and the requirement that makes hexagonal bulb spanner need not other assembly additionally is installed and can satisfy cost and process velocity, the present invention really has cost, need not to assemble the advantage fast with process velocity compared to traditional hexagonal bulb spanner.
The present invention relies on the bulb end to be provided with most bite, and therefore when the bite of skidding broke away from drive hole, the bite that also has other can be attached at drive hole.Because a plurality of contact-making surfaces of bite force in drive hole, and can reach the effect of better interlock.
