4. The smart watch according to claim 2 , wherein the diffusing apparatus comprises an antistatic layer, a polyethylene terephthalate layer, and a diffusion layer which are sequentially stacked.

5. The smart watch according to claim 2 , wherein the fixing apparatus further comprises:
a spotlight apparatus disposed on a surface of the fixing plate facing the skin, the spotlight apparatus being configured to correspond to a position of the receiving optical fiber, and being configured to improve an angle of a reflected light received by the receiving optical fiber; and
a fixing block configured to connect the spotlight apparatus to the fixing plate.

6. The smart watch according to claim 2 , wherein the fixing apparatus further comprises:
a diffusing apparatus disposed on a surface of the fixing plate facing the skin, the diffusing apparatus being configured to correspond to a position of the transmitting optical fiber, and being configured to increase an exit angle of an infrared light output from the transmitting optical fiber;
a spotlight apparatus disposed on the surface of the fixing plate facing the skin, the spotlight apparatus being configured to correspond to a position of the receiving optical fiber, and being configured to increase an angle of a reflected light received by the receiving optical fiber; and
a fixing block configured to connect the diffusing apparatus and the spotlight apparatus to the fixing plate; respectively.

7. The smart watch according to claim 2 , wherein the fixing apparatus comprises:
a fixing plate disposed inside the watchband; and
a fixing band configured to fix the output end of the transmitting optical fiber and the receiving end of the receiving optical fiber on the fixing plate.

8. The smart watch according to claim 7 , wherein the output end of the transmitting optical fiber is oppositely disposed with the receiving end of the receiving optical fiber.

9. The smart watch according to claim 8 , wherein both an end face of the output end of the transmitting optical fiber and an end face of the receiving end of the receiving optical fiber are perpendicular to a plane of the fixing plate.

10. The smart watch according to claim 7 , wherein the fixing apparatus further comprises a reflector plate disposed between the output end of the transmitting optical fiber and the receiving end of the receiving optical fiber.

11. The smart watch according to claim 7 , wherein, in the output end of the transmitting optical fiber and the receiving end of the receiving optical fiber, an optical fiber wall on the side away from the skin is longer than an optical fiber wall on the side adjacent to the skin.

12. The smart watch according to claim 1 , wherein the processing apparatus comprises:
an optical transmitter connected to the transmitting optical fiber, the optical transmitter being configured to generate an infrared light;
an optical receiver connected to the receiving optical fiber, the optical receiver being configured to receive a reflected light generated after the infrared light illuminates skin and convert the reflected light into an electrical signal; and
a processor connected to the optical transmitter and the optical receiver, respectively, the processor being configured to control the optical transmitter to generate the infrared light and receive the electrical signal sent by the optical receiver, and being configured to process the electrical signal to obtain the pulse information.

13. The smart watch according to claim 1 , wherein the watchband comprises:
