The invention discloses a bolt fastener with a movable bolt head. The bolt fastener comprises the movable bolt head and a bolt rod. A rod body of the bolt rod comprises an upper polygonal head and a lower screw. An outer hexagonal edge is arranged on the outer side of the movable bolt head, and a hole in the inner side is set to be an inner polygonal hole matched with the upper polygonal head. Themovable bolt head is in cup joint to the outer side of the upper polygonal head and can slide up and down on the upper polygonal head. One side edge of the outer side of the upper polygon is providedwith a vertical strip-shaped groove, one side edge of the outer side of the movable bolt head is provided with a threaded hole corresponding to the strip-shaped groove in position, and a positioningbolt is arranged in the threaded hole. The bolt fastener with the movable bolt head is simple in structure, convenient to install and manufacture, simple and fast in operation, capable of effectivelyadjusting the position of the bolt head above the bolt and effectively adjusting the length of the non-thread section and high in flexibility and practicability.
Description
Technical field: [0001] The invention relates to a bolt fastener with a movable bolt head, and relates to the technical field of bolt fasteners. Background technique: [0002] Fasteners, also known as standard parts in the market, are a general term for a class of mechanical parts used when two or more parts (or components) are fastened and connected into a whole. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used mechanical basic parts and are in great demand. At present, the bolt heads of many bolt fasteners are fixed, and their positions on the bolt rods cannot be adjusted, so the practicability is not high. Invention content: [0003] The technical problem to be solved by the present invention is to provide a bolt fastener with a movable bolt head, which has a simple structure, is convenient to install and manufacture, and...
