[0002] There are many types of fasteners. In a broad sense, they can refer to all mechanical parts used for fastening connections. They are commonly seen in mechanical manufacturing, bridge construction, and the processing of vehicles, ships, aircraft, etc. They often appear in sets such as bolts and nuts, and vary in size and specifications to install different components.

[0003] In the past, most bolt fasteners had a slot at the top for a screwdriver or special-shaped tool to connect to. However, the number of tools that can be carried at one time is limited. If the tool rod does not match the bolt slot, a new one needs to be found, which is time-consuming and not beneficial to the assembly process.

[0004] Now, a new type of high-strength and lightweight fastener with an improved structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-strength and lightweight fastener with an improved structure to solve the problem of fixing the specifications of the plug-in slot body proposed in the above background technology.

[0015] (1) By providing a hexagonal chamber inside the top of the rotary block, the screw rod is rotated in the three slots according to the specifications of the end of the tool to be inserted, and the screw rod can be screwed in and out of the screw hole. The thin rods embedded in the slots on both sides serve as a limit. The push block connected to the screw rod is rotated horizontally to slide, and then tightly fits around the tool rod body smaller than the hexagonal chamber and is clamped and fixed. After the fastener is installed, this structure can also be used to connect other objects;

[0016] (2) By fixing a suction cup on the top of the sleeve, when the threaded barrel in the nut block is rotated along the bolt rod by using a rotary blade, the four groups of suction cups on the surface of the nut block will be squeezed and pressed against the fitting between the nut block and the rotary block. At this time, the sleeve will pass through the through slot to squeeze the spring outside the guide rod and provide reverse support force, preventing the suction cup from leaving the adsorbed object and reinforcing the nut block, thereby improving the connection strength of the fastener;

[0017] (3) A threaded barrel is movably connected at the center of the nut block. The nut block and the internal threaded barrel are not fixedly connected. The nut block can be raised or lowered by turning the rotary vane. At this time, the rotary vane is also connected to the surface of the plug rod on both sides through the annular groove. The balance of the rotary vane during rotation is maintained under the lubrication of the ball. After the threaded barrel defines the position of the nut block, the orientation of the assembly blocks on both sides of the nut block can be adjusted, and screws and other objects can be installed in the holes to tightly connect them with the clamping objects.

[0026] Specifically, if Figure 1 and Figure 2 As shown, according to the specifications of the end of the tool to be inserted, the screw rod 14 is rotated in the three slots 15 respectively, and the screw rod 14 can be screwed in and out of the screw hole 16, and is restricted by the thin rods 12 embedded in the slots 13 on both sides. The push block 6 connected to the screw rod 14 is rotated horizontally to slide, and then fits tightly around the tool rod body in the hexagonal chamber 5 which is smaller than the hexagonal chamber and is clamped and fixed.

[0027] A circular groove 17 is provided on both sides and the front and rear ends of the top of the nut block 1, and a hidden chamber 20 is provided below the circular groove 17. A through groove 18 is provided between the circular groove 17 and the hidden chamber 20. A guide rod 22 is fixed to the bottom of the hidden chamber 20, and a sleeve 19 is sleeved on the upper part of the outer portion of the guide rod 22.

The thin rods 12 embedded in the slots 13 on both sides serve as restrictions. The push block 6 connected to the screw rod 14 is rotated horizontally to slide, and then fits tightly around the tool rod body smaller than the hexagonal chamber 5 and is clamped and fixed. The nut block 1 is not fixedly connected to the internal threaded barrel 8. The nut block 1 can be lifted or lowered by turning the rotary piece 9.
