The inner top surface 131 and medial surface 132 and a groove bottom 134.
In other words, a septal surface 133 is respectively formed between the inner top surface 131 of each arrival slot 13 and two medial surfaces 132.
Multiple moving parts 40 are installed in each arrival slot 13 of the external unit 1 respectively；In the present embodiment, each moving part 40 is
For blob of viscose slightly elastically deformable.
There is each moving part 40 inner top surface 131 of the 41 arc-shaped correspondence external unit 1 of an outer top surface, an inner top surface 45 to be in
Arc is located at the opposite of the outer top surface 41, the medial surface 132 of two lateral surfaces, the 42 arc-shaped correspondence external unit 1, two medial surfaces
44 are formed with an opening M therebetween.
Wherein, a septal surface 43 is respectively formed between the outer top surface 41 of each moving part 40 and two lateral surfaces 42, and it is each with this
A gap G is formed between the septal surface 43 of arrival slot 13.
In addition, being respectively formed with one between the inner top surface 45 of each moving part 40 and two medial surfaces 44 inside contracts slot 46.
Furthermore the both ends of the moving part 40 respectively there is a lug 47 to be formed between the outer top surface 41 and inner top surface 45,
In the both ends of the moving part 40 be respectively formed with a pillar 48 between the corresponding medial surface 44 of its each lateral surface 42.
One inscribed unit 5, fitting 50 is spirally connected with multiple bolts 70 with a termination case 60 and is formed in the present embodiment is by one.
There is the interior fitting 50 ontology 51, an axis hole 52, multiple 53 spaced radials of rib that support to be arranged.
Wherein, this, which respectively supports rib 53, has both sides of the chest side 531 respectively by being butted on two medial surfaces 44, Yi Jiyi of each moving part 40
