1. A linkage supporting device for supporting a display on a working surface, comprising: a base that can be placed on the working surface;a first shaft fixed to the base;a second shaft fixed to the base without coinciding with the first shaft;a first bar member having a main bar having a first end, a second end and a receiving space, the first end pivotally disposed on the first shaft;a third shaft for the second end of the main bar to be pivotally disposed thereon;a second bar member having one end pivotally disposed on the third shaft;a fourth shaft for the other end of the second bar member to be pivotally disposed thereon;a third bar member having one end pivotally disposed on the fourth shaft;a fifth shaft for the other end of the third bar member to be pivotally disposed thereon;a fourth bar member that has a sliding bar slidably received in the receiving space of the main bar and having a head end pivotally disposed on the fifth shaft;a sixth shaft for a tail end of the sliding bar to be pivotally disposed thereon;a fifth bar member having two ends pivotally disposed on the sixth shaft and the second shaft, respectively; anda spring member received in the receiving space of the main bar and having two ends connected to the first bar member and the fourth bar member, respectively;wherein when the display is moved from a higher position to a lower position, the fourth shaft rotates around the third shaft and the second bar member pivotally drives the third bar member to move, so as to cause the sliding bar to slide in the receiving space, thereby increasing a resistance force of the spring member. 2. The linkage supporting device of claim 1, wherein the spring member is a compression spring, and wherein when the display is moved from the higher position to the lower position, the fourth shaft rotates around the third shaft to shorten a distance between the fourth shaft and the second shaft and cause the third bar member to move so as to cause the sliding bar to slide toward the first end of the main bar, thereby compressing the spring member. 3. The linkage supporting device of claim 1, wherein the first shaft, the third shaft, the fifth shaft and the sixth shaft are on a same plane, and the second shaft and the fourth shaft are not on the plane. 4. The linkage supporting device of claim 1, wherein the base has a base body disposed on the working surface, and an inner plate and an outer plate perpendicularly extending from the base body, the first shaft is fixed on the outer plate, and the second shaft is fixed on the inner plate. 5. The linkage supporting device of claim 1, wherein the first bar member further has a torque adjusting unit that adjusts a position of a sliding block in the receiving space, and one end of the spring member abuts against the sliding block. 6. The linkage supporting device of claim 5, wherein the first bar member further has a guiding bar disposed on the main bar, the fourth bar member further has a wing plate covering the guiding bar, and the other end of the spring member abuts against the wing plate. 7. The linkage supporting device of claim 6, wherein the spring member is disposed around the guiding bar. 8. The linkage supporting device of claim 1, wherein the first bar member further has a cover configured to the main bar through a screw group passing through a through groove of the sliding bar. 9. The linkage supporting device of claim 1, further comprising a display holder pivotally disposed on the third shaft for holding the display.
