1. a clamping device (12), comprises positive shape part (14,114,214) and cloudy shape part (16,116,216) that relative to each other can adjust between non-clip position and clip position;

  • Described positive shape part comprises;

    First component main body (28), has the first component axis (B) and first component front surface (34) that limit fore-and-aft direction;

    Relative to the locking projection (36,136,236) that described first component front surface (34) extends forward, described locking projection has locking projection radius (r2), locking projection axis (C) and locking projection front surface (38), and has the rotational symmetry around locking projection axis (C);

    AndRelative to the alignment protrusion (40,140,240) that described locking projection front surface (38) extends forward, described alignment protrusion has alignment protrusion axis (E) and alignment protrusion front surface (42), and described alignment protrusion axis (E) and described locking projection (C) separate the distance of non-zero;

    AndDescribed cloudy shape part comprises;

    Second component main body (17), has the second component axis (G) and second component rear surface (54,154,254) that limit fore-and-aft direction;

    Extend forward relative to described second component rear surface (54,154,254) and have the lock hole (52,152,252) of lock hole front end (62), described lock hole comprises;

    There is the patchhole part (58) of patchhole radius (R2), part-circular cross section and patchhole axis (K);

    AndThere is the clamp bore portion (56) of clamp pore radius (R1), part-circular cross section and clamp axially bored line (H), described clamp axially bored line (H) and described patchhole axis (K) separate the first distance (M) of non-zero, and described clamp bore portion and described patchhole part merge;

    AndRelative to the mating holes (64,164,264) that described lock hole front end (62) extends forward, described mating holes has mating holes axis (N), and described mating holes axis (N) and described clamp axially bored line (H) separate the second distance (Q) of non-zero;

    Wherein;

    At described non-clip position;

    Described alignment protrusion occupies described mating holes;

    Described locking projection occupies the described patchhole part of described lock hole;

    Interference engagement is not formed between described locking projection and described lock hole;

    AndDescribed positive shape component can remove from described cloudy shape component;

    AndAt described clip position;

    Described alignment protrusion adjoins a part for described mating holes;

    Described locking projection occupies the described clamp bore portion of described lock hole;

    Described locking projection adjoins the clamping surface (60) of described clamp bore portion;

    Interference engagement is formed between described locking projection and described lock hole;

    AndDescribed clamp bore portion (56) need not any extras and remain locked on described locking projection (36);

    Described locking projection (36) is along the adjacent described clamping surface (60) of the clamp angular region (α

    ) being greater than 180 °
