It is sequentially compressed to top, while guaranteeing card ear 121 and 114 location fit of step surface, specifically, card ear 121 includes and revolving part
The body part 1211 and extended by body part 1211 and be used to hold with the hook of 114 location fit of step surface that 12 peripheral surface connects
Portion 1212, body part 1211 are equipped with the abutting arrangement abutted with inclined surface 113.In this way, when card ear 121 rotates, body part
1211 abutting arrangement will sequentially be compressed along the bottom of inclined surface 113 to top, and when the top of inclined surface 113,
Scratching part 1212 and 114 location fit of step surface, to realize being rotatably assorted revolving part 12 and fixing piece 11.
Refinement ground, in order to guarantee that abutting arrangement can preferably compress inclined surface 113, body part in the course of rotation
1211 is parallel with inclined surface 113.In this way, during rotation, body part 1211 remains parallel with inclined surface 113,
And since inclined surface 113 is to rise, abutting arrangement becomes larger the active force of inclined surface 113.
The preferred embodiments one of specific structure about abutting arrangement: as shown in figure 3, abutting arrangement includes being set to ontology
Groove 1213 in portion 1211 and extended by the notch of groove 1213 and the abutting that is formed and be used to abut with inclined surface 113
Piece 1214.Since the height of inclined surface 113 is become larger from bottom to top, in order to adapt to this kind variation, support
Contact pin 1214 will carry out the deformation of appropriateness, and the inner cavity of groove 1213 is just that contact piece 1214 provides the space of deformation.Carefully
Change ground, contact piece 1214, which has, to be connect with the small end 1215 connect at the notch of groove 1213 and with small end 1215 and vacantly big
End 1216, big end 1216 is sequentially compressed along the bottom of inclined surface 113 to top.
The preferred embodiments two of specific structure about abutting arrangement: abutting arrangement is to be convexly equipped in supporting for body part 1211
Connect column.In this embodiment, abutting column will sequentially compress along the bottom of inclined surface 113 to top, and due to inclined surface 113
Height be to be become larger from bottom to top, therefore, in order to adapt to this kind variation, body part 1211 will carry out appropriateness change
Shape.
Refinement ground, as shown in figure 3, hook is held in order to enable the location fit of scratching part 1212 and step surface 114 is more firm
Portion 1212 has elasticity, is equipped between body part 1211 and scratching part 1212 for providing elastic shrinkage recovery for scratching part 1212
The gap slot 1217 in space.In this way, also will do it corresponding change when scratching part 1212 falls into step surface 114 by rotary state
Shape is come the case where adaptation suddenly with the cooperation of step surface 114.
In the present embodiment, as shown in Figures 5 to 9, in order to enable revolving part 12 and the rotation connection of fixing piece 11 are more steady
Gu specifically, the quantity of card ear 121 is set as at least two, at least two card ears 121 are equal in being spaced in the peripheral surface of revolving part 12
Setting, the quantity of the quantity of through slot 112, the quantity of inclined surface 113 and step surface 114 is equal with 121 quantity of card ear, at least
Along the circumferentially-spaced equal setting of through-hole 111, fixed plate corresponds to each through slot 112 and is formed with an inclined surface two through slots 112
113, the top of each inclined surface 113 and the medial surface of fixed plate form step surface 114.Wherein, the quantity of card ear 121, logical
The quantity of the quantity of slot 112, the quantity of inclined surface 113 and step surface 114 can be selected according to actual use situation.
Preferably, as shown in Figures 5 to 9, the quantity of card ear 121 is set as two, and two card ears 121 are in the circumferential table of revolving part 12
It is oppositely arranged on face, the quantity of the quantity of through slot 112, the quantity of inclined surface 113 and step surface 114 is set as two, two through slots
112 are oppositely arranged on the side wall of through-hole 111.In this way, fixed with two step surfaces 114 respectively by two symmetrical card ears 121
Position cooperation, so that revolving part 12 imposes symmetrical clamping force to fixing piece 11, so that the company of revolving part 12 and fixing piece 11
It connects firm.
About the specific preferred embodiment of inclined surface 113, as shown in Fig. 3, Fig. 5, Fig. 6 and Fig. 7, inclined surface 113
Connect to forming wedge-shaped surface with step surface 114, inclined surface 113 connect with the inner wall of through slot 112 and along through slot 112 to platform
The direction of terrace 114 rises.In this way, abutting arrangement will press on inclined surface first when card ear 121 just passes through through slot 112
On 113, and the inner wall for rising to step surface 114 is compressed along the direction of through slot 112 to step surface 114, scratching part 1212 with
114 location fit of step surface.In this way, may make by setting inclined surface 113 in rotation process, abutting arrangement and nauropemeter
The inner wall in face 113 compresses power variation can constantly be adjusted.
As shown in Figures 2 to 4, in order to enable the connection of revolving part 12 and fixing piece 11 has Packed effect, specifically,
The lateral surface of fixing piece 11 be equipped with along through-hole 111 circumferentially around seal groove 115, shape in the peripheral surface of revolving part 12
