A belt structure includes a first housing, a second housing, a third housing and a belt. The two ends of the belt are respectively connected to the first housing and the third housing, which can be buckled together quickly. The second housing and the first housing are connected, so that a mechanism for fine tuning the belt can be formed through the gear, the driving element and the resisting element in the first and the second housing, thereby a belt structure with fast buckling capability and fine tuning function can be achieved.

What is claimed is: 1. A belt structure for binding a human body for first aid, comprising: a belt for surrounding the human body; a first housing, wherein the first housing has a hollow axle pipe at the front section thereof for fixing the front end of the belt, at least a gear is mounted on the hollow axle pipe, the first housing has at least a resisting element mounted therein for engaging the gear, the first housing has at least a resisting-element window formed thereon for exposing the two ends of the resisting element, the first housing also has a buckling trough mounted at the rear section thereof and an engaging element mounted therein, and the resisting element and the engaging element are respectively biased by an elastic element at one end thereof; a second housing, wherein the second housing is covered on the hollow axle pipe and the resisting element of the first housing, the second housing has an axle pillar mounted therein for extending into the hollow axle pipe, the second housing has at least a driving element mounted thereinside and an elastic element biasing the driving element, the second housing has at least a window formed thereon for exposing the driving element, each gear inside the first housing is engaged by the driving element, and the driving element has a bulge mounted thereon for engaging the resisting element as the driving element is moving backward, thereby the movement of the driving element rejects the resisting element to loose the gear; and a third housing, wherein the third housing has an opening for fixing the rear end of the belt and another opening for extending out thereof, the third housing also a pressing shaft for pressing and fixing the belt, and the third housing further has a buckling element at the other end thereof, wherein the two ends of the belt are respectively fixed at the first housing and the third housing and form a circular belt structure through the first housing and the third housing being buckled together, the second housing turns upwardly by using the axle pillar in the hollow axle pipe as the axle center so as to drive the gear by the driving element and also engaging and fixing the gear by the resisting element as the second housing is homed, and the engaging element and the buckling element respectively of the first housing and the third housing are capable of being released fast for separating the first housing and the third housing, so that a belt structure capable of being fast buckled and loosed and capable of fine tuning the level of tightness is achieved. 2. The belt structure as claimed in claim 1, wherein the resisting element is an integrally formed resisting element. 3. The belt structure as claimed in claim 2, wherein the bulge of the driving element is toward one side of the integrally formed resisting element, so that when the driving element is moving backward, the bulge of the driving element backwardly engages the two exposed ends of the resisting element, thereby the driving element and the resisting element simultaneously loose the gear so as to loose the belt. 4. The belt structure as claimed in claim 3, wherein the driving element is an integrally formed driving element. 5. The belt structure as claimed in claim 4, wherein the integrally formed driving element in the second housing engages each gear, and the second housing has an opening at the top thereof for exposing the integrally formed driving element. 6. The belt structure as claimed in claim 1, wherein the second housing has a driving element respectively at the right side and the left side thereof. 7. The belt structure as claimed in claim 6, wherein the first housing has a resisting element respectively at the right side and the left side thereof. 8. The belt structure as claimed in claim 1, wherein the bulges of the driving elements are toward one side of the resisting element, so that when the driving elements are moving backward, the bulges of the driving elements backwardly engages the respective two exposed ends of the resisting elements, thereby the driving elements and the resisting elements simultaneously loose the gear so as to loose the belt. 9. The belt structure as claimed in claim 1, wherein the resisting element and the driving element simultaneously engage the gear, and when the second housing moves upward by taking the axle pillar and the hollow axle pipe as the axle center, the driving element also is moved to drive the turning of the gear and the hollow axle pipe, thereby tightening the belt on the hollow axle pipe and also achieving a fine tuning mechanism. 10. The belt structure as claimed in claim 1, wherein the first housing has a buckling trough mounted at the rear section thereof for receiving the buckling element of the third housing, and the engaging element disposed in the buckling trough is buckled with the buckling element so as to connect the first and the third housings together. 11. The belt structure as claimed in claim 1, wherein through pressing the engaging element of the first housing to release the buckling element, the first housing and the third housing, which are originally buckled together, are separable. 12. The belt structure as claimed in claim 1, wherein the plural protruding teeth on the gear are bent toward one identical direction. 13. The belt structure as claimed in claim 1, wherein the elastic element for rejecting to the driving element, the resisting element and the engaging element is a spring. 14. The belt structure as claimed in claim 1, wherein the elastic element for biasing the driving element, the resisting element and the engaging element is an elastic piece. 15. The belt structure as claimed in claim 1, wherein the pressing shaft of the third housing further comprises patterns on the surface thereof for increasing friction, and the two ends thereof are exposed out of the third housing and manually moved to press and fix the belt. 16. The belt structure as claimed in claim 1, wherein the first housing is capable of being separated into two sub housings, which can be re-assembled, according to the different functions of buckling and fine tuning. 17. The belt structure as claimed in claim 1, wherein a time alarm is further mounted on the first housing, the second housing and the third housing.
