[0002] Double bolt head bolt, also known as double head screw or double head stud, is used for the fixed link function of connecting machinery, and both ends of the double bolt head bolt have threads, and the middle screw rod can be thick or thin. However, during use of the double bolt head bolt, the nut can rotate freely on the surface of the double bolt head bolt, causing friction between the double bolt head bolt and the nut, which leads to the double bolt head bolt slipping. Therefore, there is a need for a double bolt head bolt that prevents slipping.

[0003] The existing patent with publication number CN220769924U discloses a double bolt head bolt that prevents slipping. The double bolt head bolt includes a double bolt head bolt body, two nuts are threadedly connected to the outer side of the double bolt head bolt body, a plurality of first toothed blocks are fixedly arranged on one side of each nut, a connecting block is fixedly arranged at each end of the double bolt head bolt body, a buckle structure is arranged inside the connecting block, a fixed rod is connected to one side of the connecting block, and a push plate is arranged on one side of each nut. The second toothed blocks on one side of the push plate are engaged with the first toothed blocks on one side of each nut. Meanwhile, the second spring inside the first support rod deforms and pushes the push plate through the second support rod, causing the push plate to tightly abut against each nut. This prevents the nuts from rotating freely and causing the double bolt head bolt to slip.

[0004] The above-mentioned solution has the following problems during implementation. The structure prevents slipping by arranging the push plate on one side of each nut and engaging the second toothed blocks on one side of the push plate with the first toothed blocks on one side of each nut. However, the support rod connected to the push plate in the device is slidingly installed and is not locked, which causes the push plate to be movable. This easily affects the engagement between the second toothed blocks and the first toothed blocks, thereby reducing the anti-slip effect of the device. To solve the above-mentioned problem, we provide a double bolt head bolt that prevents slipping. UTILITY MODEL CONTENTS
