Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
As shown in Fig. 1 ~ Fig. 3, the floating type screw assembly for being not easy to deviate from of one kind of the utility model, including nut 1, screw
2, nut 1 is made of Nut column 11, clamping plate slot 12, boot segment 13 and nut cap 14, annular stop boss 15, wherein nut cap
14 and boot segment 13 be located at the both ends of nut 1, since boot segment 13 toward 14 direction of nut cap be successively arranged clamping plate slot 12,
