Description

Hexagon bolt with length adjustment mechanism

Technical Field

The utility model relates to a bolt technical field especially relates to a hexagon bolt with length adjustment mechanism.

Background

Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.

At present, current hex bolts still has the weak point, and current hex bolts length is comparatively fixed, and it is when carrying out the screw that is not the match size and close soon, two kinds of circumstances often appear: the screw depth is too shallow and leads to the unable normal close of screwing of bolt to and when the screw was too deep, the operation appears turning round number too much easily and leads to work piece outward appearance wall to damage, and hexagon bolt's length can not carry out length adjustment according to the demand, thereby has reduced hexagon bolt's application scope.
