Wall extension, the wall extension extend to can with periphery wall of another rotary body in shaft coordinate subject to.The specific revolving part
First limiting section can be that the fixture block being arranged on wall extension or protrusion, the second limiting section for limiting the revolving part of cooperation therewith then may be used
For the protrusion or fixture block being arranged on periphery wall.When specific rotary body rotation drives the rotation of its wall extension, the first limiting section is turning
The second limiting section being limited in dynamic circumferential direction on another rotary body periphery wall.
For the situation of axial-rotation limit, the first limiting section corresponding central angle in the circumferential direction of shaft is a1, second
Limiting section corresponding central angle in the circumferential direction of shaft is a2, above-mentioned central angle exists by the first limiting section and the second limiting section respectively
Occupied arc length determines in the circumferential direction of shaft.The rotational angle size of the relatively previous revolving part of latter revolving part is i.e. by central angle
a1+a2It determines, i.e., rotational angle is 360- (a1+a2).Total rotational angle that latter revolving part can rotate around the shaft is 720- (2a1+
a1+b).Therefore, by the duplication in revolving part upper limit portion, the revolving part for being connected with the second subject matter can be made to carry out big model
Enclose the rotation of angle.For the situation of radial rotary limit, the first limiting section corresponds to the central angle of spindle central on wall extension
For a3, the second limiting section corresponding central angle in the circumferential direction of periphery wall is a4, the relatively matched revolving part of specific revolving part
Rotational angle size i.e. by a3+a4It determines, i.e., rotational angle is 360- (a3+a4)。
Above-mentioned first limiting section, the second limiting section and third limiting section can phases in the circumferentially upper corresponding central angle of shaft
It together, also can be respectively different.By the design of central angle, the rotation model for the revolving part for being connected with the second subject matter can be flexibly controlled
It encloses.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
