[0002] The ear is a component for connecting the watch band and the watch dial of the wristwatch, and the form, material and use state of the ear are of great significance for the identification and maintenance of the wristwatch. Specifically, the ear is a steel rod between the watch band and the watch dial, which can adjust the length and be inserted into or pulled out of the ear hole at the two ends of the watch dial according to the use requirement, so as to realize the disassembly of the watch dial and the watch band.

[0003] Generally, the ear batch can be pushed by using the ear batch to resist the end of the ear during disassembly. In order to avoid the slippage of the ear batch when clamping the end of the ear, a joint head is arranged outside the end of the ear in the prior art. The common joint head is a single joint head. However, there is limitation in blocking the ear batch only by the joint head. The smooth surface makes the ear batch slip when force is applied, and there is room for technical improvement. UTILITY MODEL CONTENT

[0005] To solve the above technical problem, the utility model provides a technical scheme of a wristwatch single joint ear structure, which comprises a round straight pipe, an ear head, and a spring located at both ends inside the round straight pipe and connected with the ear head.

[0006] A pin hole is arranged at one end of the ear head away from each other, and the other end of the pin hole is spherical.

[0007] A joint head is arranged between the pin hole and the ear head and is composed of two hollow cylinders, and the outer diameter of the hollow cylinder close to the ear head is larger, and the joint head is in a stepped shape.

[0008] An auxiliary limiting mechanism is arranged at both ends inside the round straight pipe and comprises a plurality of clamping blocks, and each clamping block comprises a metal base and a silica gel clamping piece.

[0009] Further, the end of the pin hole is chamfered, and the spherical surface is smoothly transitioned.

[0010] Further, the corners of the joint head are sharp right angles.

[0011] Further, a lining ring is arranged at both ends inside the round straight pipe, and the side surface of the clamping block away from each other is connected with the lining ring.

[0012] Further, the round straight pass is provided with limiting grooves near both ends, and the limiting grooves are circular annular; and the two sides of the watchband are provided with ridge-shaped protrusions capable of extending into the limiting grooves.

[0013] Further, the limiting grooves and the round straight pass are smoothly connected.

[0014] Compared with the prior art, the utility model has the advantages of:

[0015] When the ear stud is used to push the nail and the ear stud head into the round straight pass, the plurality of clamping blocks enter the corresponding rectangular grooves to achieve auxiliary limiting, and the ear stud head is self-limited at this time, the next step of taking down the round straight pass is facilitated, and the situation that the ear stud slips to cause unstable clamping and pushing under continuous force can be avoided.

[0016] The limiting grooves for limiting the watchband are arranged on the round straight pass, so that the watchband is not easy to slide outside the round straight pass, and the quality of the whole precision part is improved. DRAWINGS

[0022] The utility model will be further described in detail in combination with the drawings.

[0023] Embodiment one, in combination with the drawings Figure 1 A wristwatch single joint head ear structure, comprising a round straight pass 1, an ear stud head 2, and a spring located in the round straight pass 1 at both ends and connected with the ear stud head 2.

[0024] In the above structure, the ear stud head 2 moves in the round straight pass 1 through the spring, and when the ear stud head 2 moves towards each other, the overall length is shortened, the ear stud head 2 can be pulled out from the corresponding ear hole of the watch dial, so as to realize the disassembly of the whole ear.

[0025] In combination with the drawings Figure 1 , 2Also includes the nail 3; total of two, respectively, in the ear head 2 away from each other end; the diameter of the nail 3 is slightly smaller than the ear head 2, the reduced diameter can facilitate the insertion of the ear hole;

[0026] Based on the above structure, the end of the nail 3 is spherical; the end of the nail 3 is chamfered, which is smooth transition with the spherical surface; so that the end of the nail 3 has a smaller contact surface when inserted into the ear hole, and reduces the hard block, facilitating the sliding;
