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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: an anti-slip screw comprises a screw rod 1 and a screw cap 3, wherein the top of the screw cap 3 is provided with a second screw hole 8, the second screw hole 8 penetrates through the top of the screw cap 3, the top of the screw cap 3 is also provided with a first screw hole 7, the first screw hole 7 is communicated with the second screw hole 8, an operator can use a straight screwdriver to rotate the screw through the arranged second screw hole 8, the second screw hole 8 is matched with the first screw hole 7, the operator can use a cross screwdriver to rotate the screw, the application range is expanded, the use of the operator is facilitated, the top of the screw cap 3 is fixedly connected with a plurality of reinforcing blocks 5 which are uniformly distributed, the contact area between the reinforcing blocks 5 and the screwdriver can be increased, thereby disperse the power of screwdriver, reduce the possibility that takes place smooth silk, and even when operating personnel uses a style of calligraphy screwdriver or cross screwdriver to take place smooth silk, the hexagon has been constituteed to a plurality of bosses 5, operating personnel can also use outer hexagonal spanner to rotate the screw, the inside symmetry of nut 3 is equipped with chute 6, chute 6 extends to the side of nut 3, when operating personnel uses a style of calligraphy screwdriver, when the smooth silk condition all appears in cross screwdriver and outer hexagonal spanner, operating personnel can also insert a style of calligraphy screwdriver in chute 6, then strike the portion of gripping of a style of calligraphy screwdriver with the hammer, make the screw rotate not hard up, the condition that the screw can't be taken out when avoiding appearing smooth silk.

Wherein, the side of the reinforcing block 5 close to the first screw opening 7 is aligned with the edge of the first screw opening 7, and the side of the reinforcing block 5 close to the second screw opening 8 is aligned with the edge of the second screw opening 8.

Wherein, screw rod 1 fixed connection is in the bottom of nut 3, and screw rod 1's bottom integrated into one piece has pointed end 2.

Wherein, the outside of pointed end 2 and screw rod 1 all is equipped with external screw thread 4.

Wherein, the width of the first screw opening 7 is equal to the width of the second screw opening 8.

The nut 3 and the reinforcing block 5 are made of carburizing steel which has high hardness and good wear resistance, and therefore, the occurrence of wire slipping is further avoided.

Specifically, during the use, operating personnel can use a style of calligraphy screwdriver or cross screwdriver to rotate the screw, because the 5 increase of boss and the screwdriver area of contact between that set up, the probability that smooth silk takes place has been reduced, if use a style of calligraphy screwdriver or cross screwdriver when the smooth silk condition appears, operating personnel can place outer hexagonal spanner in the outside of boss 5, rotate the screw, if smooth silk has also appeared in using outer hexagonal spanner, operating personnel can also insert a style of calligraphy screwdriver in chute 6, then strike the portion of gripping of a style of calligraphy screwdriver with the hammer, make the screw rotate not hard up, the condition that the screw can't be taken out when avoiding appearing smooth silk.
