[0002] It is a common design to have rivet posts on the back of the LCD display module. The rivet posts are usually embedded into the metal sheet on the back of the backlight through a riveting process. The rivet posts are used for positioning and guiding the assembly of the display module and the customer's whole machine motherboard. Generally, customers require small diameters and high heights. However, since the rivet posts are riveted to the iron frame behind the backlight, they are easy to fall off and tilt during transportation and use (such as Figure 1 ), affecting product quality and leading to serious customer complaints.

[0003] For example, Chinese utility model patent (CN202021238006.X) discloses a rivet with an anti-pull rivet head loosening head. The utility model discloses a rivet with an anti-pull rivet head loosening head, including a rivet sleeve, wherein the inner wall of the rivet sleeve is provided with a card groove on both sides, a rivet body is inserted in the rivet sleeve, a rivet head is provided on the top of the rivet body, a connecting groove is provided in the rivet body, an inner rivet is connected to the connecting groove, grooves are provided on both sides of the outer wall of the inner rivet, a spring sleeve rod is fixedly installed in the groove, a card block is sleeved on the spring sleeve rod, through holes are provided on both sides of the outer wall of the rivet body, a cross groove is provided on the top of the inner rivet, the rivet body is provided with an inner cavity, a thread is provided in the rivet body, a thread is provided on the outer wall of the inner rivet, the rivet body is threadedly connected to the inner rivet, and a boss is fixedly provided at one end of the rivet sleeve. The device is a self-contained locking mechanism that can fix the rivet sleeve and is an easy-to-use anti-pull rivet head loosening head rivet.

[0004] Therefore, in order to solve the above-mentioned problem of defective products, this patent proposes a solution to prevent rivets from tilting. While meeting the customer's needs for positioning and guiding assembly, it avoids the occurrence of defective products such as rivet uprights falling off and tilting, thereby improving production yield.

When dealing with some situations where the length of the inner cavity is inconsistent, it is not convenient to fine-tune the length of the rivet. This makes it difficult to adjust the end of the rivet to an appropriate length when the rivet length is constantly extended. Utility Model Content
