[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] As Figures 1 - 3 shown, a high-precision compound optoelectronic encoder includes an encoder body 1 and a shaft seat 2 fixedly connected to the lower surface of the encoder body 1. A storage housing 3 is rotatably connected to the outside of the shaft seat 2. An inlet hole 4 is opened on the left side of the outer circumferential surface of the storage housing 3, and an outlet hole 5 is opened on the right side of the outer circumferential surface of the storage housing 3. An elastic mechanism 6 is provided inside the shaft seat 2 and extends to the outside. The elastic mechanism 6 includes a chute 61 opened inside the shaft seat 2. A slider 62 is slidably connected inside the chute 61. A sliding rod 63 is fixedly connected to the lower surface of the slider 62. A return spring 64 is sleeved outside the sliding rod 63, and the lower end of the sliding rod 63 is fixedly connected to the inner bottom of the storage housing 3.

[0019] By adopting the above technical solution, the storage case 3 can store the wire body of the encoder body 1. When storing, the storage case 3 can be pulled downward, the slider 62 slides inside the chute 61, and the return spring 64 is compressed. The wire body near the wire outlet end of the encoder body 1 enters the storage case 3 through the wire inlet hole 4, and one end passes through the wire outlet hole 5. Releasing the storage case 3 can store the excess wire body, effectively solving the problem of messy wire bodies. Messy wire bodies are prone to accidental pulling, affecting the normal operation of the encoder body 1.

[0020] As Figures 2 - 3 shown, a threaded barrel seat 7 is fixedly connected to the left side of the outer cylindrical surface of the encoder body 1, and the threaded barrel seat 7 is of an open design.

[0021] Furthermore, a nut 8 is threadedly connected to the outer cylindrical surface of the threaded barrel seat 7, and the wire body of the encoder body 1 passes through the inside of the threaded barrel seat 7.

[0022] Furthermore, a threaded hole 9 is provided above the threaded barrel seat 7 on the left outer cylindrical surface of the encoder body 1, and a fixing rod can be threadedly connected inside the threaded hole 9.

[0023] Working principle: When using this high-precision compound photoelectric encoder, first, the storage case 3 can store the wire body of the encoder body 1. When storing, the storage case 3 can be pulled downward, the slider 62 slides inside the chute 61, and the return spring 64 is compressed. The wire body near the wire outlet end of the encoder body 1 enters the storage case 3 through the wire inlet hole 4, and one end passes through the wire outlet hole 5. Releasing the storage case 3 can store the excess wire body. Tightening the nut 8, the nut 8 can exert pressure on the threaded barrel seat 7, and the cracked threaded barrel seat 7 can exert pressure on the wire body to fix the outer surface of the wire body and enhance the firmness of the connection. This is the working principle of this high-precision compound photoelectric encoder.
