Detailed Description

The utility model is described in further detail below with reference to fig. 1-4.

The embodiment of the utility model discloses a four-jaw nut.

Referring to fig. 1-3, the four-jaw nut comprises a nut body 1, four connecting blocks 2 are uniformly distributed at the top of the nut body 1, a T-shaped groove 3 is formed in one end of each connecting block 2, a fixing jaw 4 is mounted in the T-shaped groove 3, a fixing piece 5 is mounted at one end of each fixing jaw 4, an inner hexagonal groove 6 is formed in the top of the nut body 1, a plurality of barb blocks 7 are fixedly connected to the inner side of each fixing jaw 4, and an organic silicon waterproof paint is coated on the surface of the nut body 1. Firstly, the fixing piece 5 is unscrewed through a screwdriver so as to relieve the fixed connection between the fixing claw 4 and the connecting block 2, then the nut body 1 is rotated through the inner hexagonal wrench matched with the inner hexagonal groove 6, so that the joint between the nut body 1 and the fixing claw 4 is loosened, the nut body 1 is driven to be separated from the contact with the fixing claw 4, the nut body 1 is conveniently taken out for replacement, the nut body 1 is conveniently taken out alone for replacement, and the damage to the mounting piece caused by disassembling and pulling the fixing claw 4 is reduced.
