The invention claimed is: 1. A terminal having a fingerprint identification function, comprising: a body having a camera and a processing unit, the camera being electrically connected to the processing unit; an optical lens assembly, used to change a focal length of the camera, located above the camera, and mounted on the body; a light-guiding fingerprint capture platform, located above the optical lens assembly, and used cooperatively with the optical lens assembly; a light source, located between the camera and the fingerprint capture platform and aside the camera, a light emitting end of the light source facing the fingerprint capture platform; a light guide member, mounted between the fingerprint capture platform and the light source; and a sliding rail, located on the body, the optical lens assembly being movably mounted on the sliding rail, the fingerprint capture platform being fixedly mounted on the optical lens assembly, and the light guide member being mounted on the optical lens assembly in a penetration manner, wherein when the optical lens assembly carries the fingerprint capture platform and the light guide member to move along the sliding rail to a first set location, the optical lens assembly and the fingerprint capture platform are located right above the camera, and the light guide member is located right above the light source; and when the optical lens assembly carries the fingerprint capture platform and the light guide member to move along the sliding rail to a second set location, the optical lens assembly and the fingerprint capture platform are located aside a place right above the camera, and the light guide member is located aside a place right above the light source. 2. The terminal having a fingerprint identification function according to claim 1 , further comprising: a switch, located aside the camera, and electrically connected to the processing unit, wherein when the optical lens assembly carries the fingerprint capture platform and the light guide member to move along the sliding rail to a first set location, the optical lens assembly comes into contact with the switch to turn the switch ( 5 ) on; and when the optical lens assembly carries the fingerprint capture platform and the light guide member to move along the sliding rail to a second set location, the optical lens assembly is separated from the switch to turn the switch off. 3. The terminal having a fingerprint identification function according to claim 2 , further comprising: a limiting member, mounted at an end of the sliding rail, to stop the optical lens assembly from slipping off the sliding rail. 4. The terminal having a fingerprint identification function according to claim 3 , wherein the switch is a toggle switch, the light source is an LED flashlight, and the limiting member is a limiting plate. 5. The terminal having a fingerprint identification function according to claim 1 , wherein the optical lens assembly comprises: a sliding support having a first through-hole, movably mounted on the sliding rail; and an optical lens, mounted in the first through-hole. 6. The terminal having a fingerprint identification function according to claim 5 , wherein the fingerprint capture platform comprises: a light-guiding platform support, mounted on the sliding support; and light-guiding platform glass, mounted on the platform support. 7. The terminal having a fingerprint identification function according to claim 6 , wherein the platform support is provided with a second through-hole, corresponding to the first through-hole. 8. The terminal having a fingerprint identification function according to claim 7 , wherein the platform glass is optical glass, the optical lens is a wide-angle lens, the first through-hole is cylindrical, and the second through-hole is flared. 9. The terminal having a fingerprint identification function according to claim 2 , wherein the optical lens assembly comprises: a sliding support having a first through-hole, movably mounted on the sliding rail; and an optical lens, mounted in the first through-hole. 10. The terminal having a fingerprint identification function according to claim 9 , wherein the fingerprint capture platform comprises: a light-guiding platform support, mounted on the sliding support; and light-guiding platform glass, mounted on the platform support. 11. The terminal having a fingerprint identification function according to claim 10 , wherein the platform support is provided with a second through-hole, corresponding to the first through-hole. 12. The terminal having a fingerprint identification function according to claim 11 , wherein the platform glass is optical glass, the optical lens is a wide-angle lens, the first through-hole is cylindrical, and the second through-hole is flared. 13. The terminal having a fingerprint identification function according to claim 3 , wherein the optical lens assembly comprises: a sliding support having a first through-hole, movably mounted on the sliding rail; and an optical lens, mounted in the first through-hole. 14. The terminal having a fingerprint identification function according to claim 13 , wherein the fingerprint capture platform comprises: a light-guiding platform support, mounted on the sliding support; and light-guiding platform glass, mounted on the platform support. 15. The terminal having a fingerprint identification function according to claim 14 , wherein the platform support is provided with a second through-hole, corresponding to the first through-hole. 16. The terminal having a fingerprint identification function according to claim 4 , wherein the optical lens assembly comprises: a sliding support having a first through-hole, movably mounted on the sliding rail; and an optical lens, mounted in the first through-hole. 17. The terminal having a fingerprint identification function according to claim 16 , wherein the fingerprint capture platform comprises: a light-guiding platform support, mounted on the sliding support; and light-guiding platform glass, mounted on the platform support. 18. The terminal having a fingerprint identification function according to claim 17 , wherein the platform support is provided with a second through-hole, corresponding to the first through-hole.
