Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1 to 3, a bolt for a brake caliper capable of being screwed in two axes includes a center axis 5, a first outer axis 4 is integrally formed on a circumferential outer wall of the center axis 5, a second outer axis 6 is integrally formed on a circumferential outer wall of the center axis 5, and the first outer axis 4 and the second outer axis 6 are protruded portions of an outer surface of the center axis 5.

Axis 5 one end integrated into one piece has slipmat 3, setting through slipmat 3, the contact friction of bolt inside the screw has been increaseed, the problem of the screw that the bolt drops has been avoided, axis 5 one end integrated into one piece has hexagonal prism 2, hexagonal prism 2 fastening strength is bigger, can use monkey wrench or open-end spanner during the installation, it is very convenient, almost all use is in various structures, and hexagonal prism 2 is located one side of slipmat 3, axis 5 one end integrated into one piece has outer side cut 1, and outer side cut 1 is located one side of hexagonal prism 2, axis 5 one end integrated into one piece has interior side cut 7, and interior side cut 7 is located one side of second

outer axle

6, 1 one side integrated into one piece of outer side cut has specification groove 8, specification groove 8 has shown the basic information of bolt.

The working principle of the embodiment is as follows: when the anti-skidding bolt is used, one side of the inner trimming edge 7 is placed into the screw hole, the hexagonal prism 2 is clamped by a tool and rotated, the middle shaft 5 is sent into the screw hole, the whole bolt is screwed, the anti-skidding pad 3 increases the contact area of the bolt and the screw hole, and the bolt is tightly contacted with the screw hole.

Example 2

Referring to fig. 4, a brake caliper bolt that can biax is screwed up, axis 5 still includes spiral ring silk 9 and screw thread 10, sets up through the cooperation of spiral ring silk 9 and screw thread 10, has increaseed the area of contact of bolt and screw, has increased contact friction to make bolt and screw link up closely, axis 5 one end and screw thread 10 fixed connection, and axis 5 one end forms the cup joint with spiral ring silk 9.
