[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0022] Reference Figure 1-Figure 5 As shown, the utility model provides a technical solution: a new ear structure that is easy to install, including a shell 1, sleeves 2 are fixed at both ends of the shell 1, a rotating shaft 3 is rotatably connected to the inside of the shell 1, and a limit plate 4 is fixed at one end of the rotating shaft 3 located inside the shell 1. The limit plate 4 is elliptical in shape, and a fixing plate 5 is slidably connected to both sides of the shell 1. A new ear body 6 is fixed to one end of the fixing plate 5, an ear hole 7 is opened inside the sleeve 2 and passes through the inside of the shell 1, and the inside of the ear hole 7 is slidably connected to the new ear body 6, a first spring 10 is fixed on both sides of the shell 1, and the other end of the first spring 10 is fixed to the fixing plate 5, a square rod 11 is slidably connected to the inside of the rotating shaft 3, and a knob 12 is fixed to one end of the square rod 11. An insertion rod 13 is fixed to one side of 12, and a slot 14 is provided on one side of the shell 1 for use with the insertion rod 13. By pulling the knob 12, the insertion rod 13 is driven to move upward and disengage from the inside of the slot 14. Then the knob 12 can be twisted, and the square rod 11 cooperates with the square groove provided inside the rotating shaft 3 to drive the rotating shaft 3 to rotate together, and at the same time drive the limit plate 4 to rotate. At this time, the limit plate 4 will contact the fixing plate 5 and squeeze the fixing plate 5. At this time, the first spring 10 begins to contract, so that the fixing plate 5 pushes the raw ear body 6 to extend to the outside of the ear hole 7 and insert it into the inside of the undrawn watchband for fixation. Then push the knob 12 again to drive the insertion rod 13 to insert into the inside of the slot 14. It is easy to install and can be completed without special tools, thereby improving the efficiency of use.

[0023] Reference Figure 3 and Figure 4As shown, in this embodiment: guide rods 8 are fixed on both sides of the interior of the shell 1, and a guide groove 9 is provided on the surface of the fixing plate 5 for use with the guide rods 8. The difference between the maximum diameter and the minimum diameter of the limiting plate 4 is greater than the diameter of the raw ear body 6 extending out of the ear hole 7. During the installation of the raw ear body 6, the guide rods 8 and the guide grooves 9 can limit the movement trajectory of the fixing plate 5 to avoid tilting, so that the raw ear body 6 can be accurately extended into the interior of the sleeve 2. By utilizing the elliptical shape of the limiting plate 4, when the limiting plate 4 is rotated, the difference between the maximum diameter and the minimum diameter of the limiting plate 4 can ensure that when the raw ear body 6 needs to be disassembled from the undrawn watchband, the moving distance of the fixing plate 5 can drive the raw ear body 6 to detach from the undrawn watchband and return to the interior of the sleeve 2.

[0024] Reference Figure 4 and Figure 5 As shown, in this embodiment: sliding grooves 16 are provided on both sides of the interior of the rotating shaft 3, and sliders 15 used in conjunction with the sliding grooves 16 are fixed on both sides of the square rod 11. A second spring 17 is fixed to the interior of the rotating shaft 3, and the other end of the second spring 17 is fixed to the square rod 11. When the operator pulls the knob 12, the structure of the slider 15 and the sliding groove 16 can prevent the operator from using too much force to pull the square rod 11 out from the interior of the rotating shaft 3, affecting the fixing effect, and in the process of pulling the knob 12, the second spring 17 is in a stretched state. When the installation of the ear body 6 is completed, the rebound force of the second spring 17 is used to pull the square rod 11 to drive the knob 12 to pull the insertion rod 13 into the interior of the slot 14, thereby completing the rapid installation of the ear body 6.

[0025] The specific steps for using the ear structure that is easy to install are as follows:

[0026] 1. When the ear body 6 needs to be installed, the knob 12 is pulled to drive the insertion rod 13 to move upward and disengage from the inside of the slot 14. Then the knob 12 can be turned, and the square rod 11 cooperates with the square groove opened inside the rotating shaft 3 to drive the rotating shaft 3 to rotate together, and at the same time drives the limit plate 4 to rotate. At this time, the limit plate 4 will contact the fixing plate 5 and squeeze the fixing plate 5, so that the fixing plate 5 pushes the ear body 6 to the outside of the ear hole 7 and is inserted into the inside of the undrawn watchband for fixation. Then, the knob 12 is pushed again to drive the insertion rod 13 to insert into the inside of the slot 14. The installation is convenient and can be completed without special tools, thereby improving the use efficiency.

[0027] Second, during the installation of the ear body 6, the guide rod 8 and the guide groove 9 can limit the movement trajectory of the fixing plate 5 to prevent tilting, thereby enabling the ear body 6 to accurately extend into the interior of the sleeve 2. Utilizing the elliptical shape of the limit plate 4, when the limit plate 4 is rotated, the difference between the maximum and minimum diameters of the limit plate 4 ensures that when the ear body 6 needs to be detached from the undrawn watchband, the moving distance of the fixing plate 5 is sufficient to drive the ear body 6 to separate from the undrawn watchband and return to the interior of the sleeve 2.

[0028] 3. When the operator pulls the knob 12, the structure of the slider 15 and the slide groove 16 can prevent the operator from using too much force and pulling the square rod 11 out from the inside of the rotating shaft 3, affecting the fixing effect. In the process of pulling the knob 12, the second spring 17 is in a stretched state. When the mounting ear body 6 is installed, the rebound force of the second spring 17 is used to pull the square rod 11 to drive the knob 12 to pull the insertion rod 13 into the inside of the slot 14, thereby completing the rapid installation of the mounting ear body 6.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
