What is claimed is: 1. Virtual reality (VR) glasses, comprising: a bottom plate, two communicating light-transmitting holes being provided on the bottom plate symmetrically; a first sealing part and a second sealing part, the first sealing part and the second sealing part being both made of a silicone material and fixed onto the bottom plate, and the first sealing part and the second sealing part being in one-to-one correspondence with positions of the two light-transmitting holes respectively; and a first lens barrel and a second lens barrel, the first lens barrel communicating with one of the two light-transmitting holes through the first sealing part, and the second lens barrel communicating with the other one of the two light-transmitting holes through the second sealing part, and the first lens barrel and the second lens barrel being configured to be able to move toward each other, wherein the first sealing part and the second sealing part are provided with bellows-type structures along an opening direction of the light-transmitting holes, and in a state where a spacing between the first lens barrel and the second lens barrel changes, the first sealing part and the second sealing part are deformed through the bellows-type structures. 2. The VR glasses as claimed in claim 1 , wherein the VR glasses further comprises a pressing plate fixed on the bottom plate, wherein the pressing plate is configured to fix an end of two ends of each of the first sealing part and the second sealing part that is closer to the bottom plate on the bottom plate. 3. The VR glasses as claimed in claim 1 , wherein an end of two ends of the first sealing part that is more away from the bottom plate is provided with a first mounting groove, and an end of two ends of the second sealing part that is more away from the bottom plate is provided with a second mounting groove, the first mounting groove wraps up an end of two ends of the first lens barrel that is closer to the bottom plate, and the second mounting groove wraps up an end of two ends of the second lens barrel that is closer to the bottom plate. 4. The VR glasses as claimed in claim 1 , wherein a first mounting plate and a second mounting plate in parallel with a movement direction of the first lens barrel and the second lens barrel are provided on the bottom plate, and the first mounting plate and the second mounting plate are respectively disposed at two sides of the first lens barrel and the second lens barrel; the first lens barrel is symmetrically provided thereon with a first sliding plate and a second sliding plate, the first sliding plate is slidably disposed on the first mounting plate and the second sliding plate is slidably disposed on the second mounting plate; the second lens barrel is symmetrically provided thereon with a third sliding plate and a fourth sliding plate, the third sliding plate is slidably disposed on the first mounting plate and the fourth sliding plate is slidably disposed on the second mounting plate. 5. The VR glasses as claimed in claim 4 , wherein the fourth sliding plate extends toward a side where the second mounting plate is located, and a third mounting plate is disposed on the bottom plate, the third mounting plate is parallel with the second mounting plate and the first mounting plate, and the third mounting plate is provided with a first sliding groove; the second lens barrel is fixedly provided with a first rack, a first gear and a second rack are disposed between the third mounting plate and the second mounting plate, the first gear is disposed between the first rack and the second rack, and both the first rack and the second rack are in mesh with the first gear; an end of the second rack passes through the first sliding groove, and when the second rack is pushed in a direction away from the first lens barrel, the first gear rotates clockwise, and the second lens barrel moves toward the first lens barrel. 6. The VR glasses as claimed in claim 5 , wherein the VR glasses comprises a boss provided between the third mounting plate and the second mounting plate, wherein the second rack is slidably disposed on the boss. 7. The VR glasses as claimed in claim 5 , wherein a third rack is provided on a side, opposite to the first rack, of the second lens barrel, and the third rack is disposed toward the third mounting plate, a fourth rack is provided on a side of the first lens barrel that is closer to the first mounting plate than the second mounting plate, the fourth rack and the third rack are oppositely disposed, the fourth rack and the third rack are in mesh with a second gear therebetween, an axis of the second gear is perpendicular to an axis of the first gear, when the first gear is in a clockwise rotation state, the second gear is also in a clockwise rotation state, and the first lens barrel and the second lens barrel move toward each other. 8. The VR glasses as claimed in claim 7 , wherein a fixing post is provided on a position, corresponding to the second gear, of the bottom plate, and the second gear is rotatably disposed on the fixing post. 9. The VR glasses as claimed in claim 4 , wherein the first mounting plate and the second mounting plate are provided with prisms, and the first sliding plate, the second sliding plate, the third sliding plate and the fourth sliding plate all provided with second sliding grooves, the prisms are cooperated with the second sliding grooves to limit the first lens barrel and the second lens barrel.
