It is appreciated that in other examples, the set-up mode of the supporting surface can be not limited to described above Vertical described matrix end face, the supporting surface can be arranged on the positioning tooth with other set-up modes.For example, institute A preset range can be met by stating formed angle between supporting surface and the end face of described matrix so that make the tumbler 41 It is described when no matter much the external force of rotation is, it will not be relatively moved all the time between intermeshing two positioning tooth phases, so as to ensure Firm position between the tumbler 41 and the fixture 21 is reliable.

Specifically, the angle between the normal of the supporting surface and the end face of described matrix is less than or equal to intermeshing Angle of friction of two positioning tooths when being in contact when, the torque no matter tumbler 41 described in outer bound pair applies is much, intermeshing Two positioning tooth phases between will not relatively move all the time, therefore, two keepers all the time be in intermeshing shape State, the tumbler 41 can not be rotated relative to the fixture 21 all the time.

Above-mentioned angle of friction is the angle of friction on ordinary meaning in Machine Design/manufacture field, and the angle of friction can be with popular Ground is interpreted as：Object is in one plane acted on by external force Fr, when the object is in the critical condition slided, the plane pair The stiction Fs of the object reaches maximum Fmax, now external force Fr and angle of the plane to the holding power Fn of the objectAlso it is maximum, angle nowReferred to as angle of friction.

Angle of friction when above-mentioned two positioning tooth is in contact is determined by the material and surface appearance of two positioning tooths.In this reality Apply in mode, the positioning tooth is the positioning steel-tooth that is made up of steel, the normal of the supporting surface and the end face of described matrix it Between angle be less than or equal to 10 degree, it is preferable that the angle between the normal of the supporting surface and the end face of described matrix is less than Or equal to 8.5 degree.

It is appreciated that in other examples, the positioning tooth can be made up of other materials, such as aluminium, copper, iron, modeling Material etc..It is appreciated that the material of two intermeshing positioning tooths be able to can also be differed with identical.When the positioning tooth is served as reasons When material beyond steel is made, angle of friction when intermeshing two positioning tooths are in contact is also with different manufacture materials And it is different.

For example, one of positioning tooth of two intermeshing positioning tooths is made up of steel, another positioning tooth is by soft Steel is made, now, and static friction factor when two positioning tooths are in contact is relatively large, the normal of the supporting surface and the base Angle between the end face of body is less than or equal to 17 degree, it is preferable that between the normal of the supporting surface and the end face of described matrix Angle be less than or equal to 16.7 degree.

For another example, one of positioning tooth of two intermeshing positioning tooths is made up of mild steel, and another positioning tooth is by Huang Copper is into now, the angle between the normal of the supporting surface and the end face of described matrix is less than or equal to 25 degree, it is preferable that Angle between the normal of the supporting surface and the end face of described matrix is less than or equal to 24.7 degree.By the keeper and institute The substantially coaxial setting of accepting hole 2131 is stated, the described matrix of the keeper is substantially discoid, and the tumbler 41 can be around The axis of the perforating 2133 is rotated relative to the fixture 21, then the end face of described matrix is approximately perpendicular to the tumbler Pivot center.Therefore, formed angle is less than or equal to mutually between the normal of the supporting surface and the end face of described matrix Angle of friction when two positioning tooths of engagement are in contact, you can be interpreted as, the normal of the supporting surface perpendicular to described with rotating Formed angle is not more than angle of friction when intermeshing two positioning tooths are in contact between the plane of the pivot center of part 41. Now, the torque that no matter tumbler 41 described in outer bound pair applies is much, and the positioning tooth 433 of the keeper 43 is all without relative institute The positioning tooth 233 for stating keeper 23 is moved, and two keepers 23,43 are in intermeshing state all the time.Even if described Capture apparatus 500 is by larger impact endurance test shock, and two keepers 23,43 also not readily disengage from engagement, so as to ensure institute The firm position stated between tumbler 41 and the fixture 21 is reliable.
