[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment of a key chain that is easy to install, including an installation box 1 that plays a fixed connection role. The top of the installation box 1 is fixedly connected with a buckle ring 2, and the buckle ring 2 can hang the key chain at a required position. A limiting groove 3 is provided inside the installation box 1, and a button 5 is elastically connected to the inner wall of the left side of the limiting groove 3 through a limiting spring 4. When the button 5 is not under force, the limiting spring 4 will push the button 5 to the right. One end of the limiting spring 4 is fixedly connected to the inner wall of the left side of the limiting groove 3, and the other end of the limiting spring 4 is fixedly connected to the left side of the button 5. The outer periphery of the button 5 is slidably connected to the inside of the limiting groove 3. The limiting groove 3 limits the button 5 to only slide left and right along the limiting groove 3. A rounded slide groove 6 is provided inside the button 5, and a limiting column 7 is slidably connected inside the rounded slide groove 6. The rounded slide groove 6 and the limiting column 7 limit the distance that the button 5 moves left and right to prevent the button 5 from leaving the limiting groove 3. The bottom of the limiting column 7 is fixedly connected to the inner wall of the bottom end of the limiting groove 3, and a lock groove 8 is provided inside the left side of the button 5.

[0032] Reference Figure 2-Figure 4 A slot 9 is provided at the bottom of the installation box 1, and a plug block 10 is slidably connected inside the slot 9. A lock hook 11 is fixedly connected to the top of the plug block 10. The left side of the lock hook 11 is engaged with the inside of the lock slot 8 to fix the plug block 10. A group of placement slots 12 are provided on both sides of the plug block 10. A positioning column 13 is fixedly connected to the inner wall of the side of the placement slot 12. Two groups of positioning columns 13 are provided. The two groups of positioning columns 13 are symmetrically arranged inside the placement slot 12. A fixing component is placed inside the placement slot 12. The fixing component is used to fix the key. The fixing component includes a belt 14. The belt 14 can pass through The keyhole is used to fix the key. The front and rear ends of the belt 14 are placed inside the placement groove 12 to form a closed ring. Positioning holes 15 are opened inside the front and rear ends of the belt 14. There are four groups of positioning holes 15. The front and rear ends of the belt 14 respectively have two groups of positioning holes 15 that are symmetrically arranged on the left and right, and are opposite to the positioning column 13. The outer periphery of the positioning column 13 is slidably connected to the inside of the positioning hole 15. The height of the positioning column 13 is the same as the height of the placement groove 12, so that after the insert block 10 is inserted into the slot 9, the belt 14 cannot fall out from between the positioning column 13 and the placement groove 12.

[0033] Working principle: when you want to fix the key conveniently, press the button 5 to the left, the button 5 pushes the lock slot 8 to move to the left and squeezes the limit spring 4 at the same time, the lock slot 8 is out of contact with the lock hook 11, then take out the plug block 10, remove the belt 14 from the inside of the placement slot 12, pass the belt 14 through the keyhole on the key, and then place the front and rear ends of the belt 14 in the placement slot 12 before and after the plug block 10, so that the positioning hole 15 is sleeved on the positioning column 13, and then insert the plug block 10 into the inside of the slot 9, release the button 5, the limit spring 4 releases the compression, and pushes the button 5 to move to the right, so that the lock slot 8 and the lock hook 11 are re-engaged, so that the key can be conveniently installed on the keychain.
