[0029] See also Figure 1-4A fastener with a limiting structure includes a fastener body 2, two workpieces 1 are arranged below the fastener body 2, the two workpieces 1 are connected through the fastener body 2, a limiting assembly 3 is arranged on the outside of the workpiece 1, the limiting assembly 3 includes a limiting frame 31, and a gasket 33 is arranged inside the limiting frame 31 and on the outer surface of the fastener body 2. During actual operation, the user can increase or decrease the number of gaskets 33 outside the fastener body 2 according to the depth that the fastener body 2 needs to be screwed into the bottom fastener body 2. After adjustment, the fastener body 2 can be screwed into the inside of the two workpieces 1, so that the connection of the two workpieces 1 can be completed, which is convenient to meet the different usage requirements of the user, and is conducive to improving the flexibility of the equipment and facilitating use. A limiting cap 36 is arranged on the outside of the head of the fastener body 2, and T-shaped grooves are opened on both sides of the limiting frame 31. 34, the T-shaped slide groove 34 is internally slidably connected with a T-shaped slider 35, one side of the T-shaped slider 35 is fixedly connected to one side of the limiting cap 36, both sides of the inside of the limiting cap 36 are fixedly connected with a clamping plate 38 through an extrusion spring 37, and the top of the limiting cap 36 is fixedly connected with a pull handle 39, and both sides of the limiting frame 31 are fixedly connected with side plates 311 through a connecting spring 310, one side of the side plate 311 and the top of the connecting spring 310 are fixedly connected with a limiting plate 312, and a limiting groove compatible with the limiting plate 312 is provided inside the T-shaped slider 35. In summary, the device can avoid the reversal of the head of the fastener body 2 due to external vibration by arranging a limiting component 3 on the outside of the workpiece 1, thereby helping to improve the stability of the equipment, making it convenient for users to protect the fastener body 2, thereby extending the service life of the equipment and facilitating the use of the staff.
[0030] The bottom of the limiting frame 31 is fixedly connected with an anti-skid protrusion 32 , and the anti-skid protrusion 32 can prevent the limiting frame 31 from being displaced during use.
[0031] A pull ring 313 is fixedly connected to the other side of the side plate 311 . The pull ring 313 facilitates the user to pull the side plate 311 .
[0032] A through hole is provided at the bottom of the limiting frame 31, and a magnet sheet is fixedly installed at the periphery of the through hole.

After connection, the T-shaped sliders 35 on both sides of the limiting cap 36 can be aligned with the T-shaped slide groove 34 inside the limiting frame 31. Before entering, the pull rings 313 on the two side plates 311 can be pulled at the same time, and the limiting plate 312 can be driven to move synchronously through the reverse movement of the two side plates 311. At this time, the T-shaped slider 35 is inserted into the inside of the T-shaped slide groove 34. When the limiting cap 36 on one side of the T-shaped slider 35 is completely engaged with the head of the fastener body 2, the two pull rings 313 can be released at the same time. Through the elastic force of the connecting spring 310, the limiting plate 312 can enter the limiting groove inside the T-shaped slider 35, and then the position of the limiting cap 36 can be limited.
[0036] By setting a limiting cap 36 on the outside of the fastener 2 and limiting the position of the limiting cap 36, the device can avoid the head of the fastener 2 from being reversed due to external vibration, thereby helping to improve the stability of the equipment, making it convenient for users to protect the fastener 2, and further extending the service life of the equipment and making it convenient for staff to use.
