8. A wear pad for a suspended load-bearing machine tool for preventing wear of a floor as set forth in claim 7, wherein: the limiting assembly (32) comprises a spur gear (326) which is connected to the limiting shaft (311) in a sliding mode, the spur gear (326) and the limiting shaft (311) are located on one side, close to the tooth groove (313), of the first bevel gear (312), the spur gear (326) corresponds to the tooth groove (313) on the first bevel gear (312), and a fixing ring (325) is fixedly connected to one side of the spur gear (326).

9. A wear pad for a suspended load-bearing machine tool for preventing wear of a floor as set forth in claim 8, wherein: the limiting component (32) further comprises a bearing (324) fixedly connected to the outer wall of the fixed ring (325), a connecting plate (323) is fixedly connected to the outer wall of the bearing (324), a connecting rod (322) is fixedly connected to the connecting plate (323), and a fixing rod (321) is fixedly connected to one end of the connecting rod (322).

10. A method of using the wear pad of a floor wear resistant suspension bearing machine tool of claim 9, comprising the steps of:

s1: firstly, pulling a fixed rod (321), inserting a straight gear (326) into a tooth groove (313) through a connecting rod (322), a connecting plate (323), a bearing (324) and a fixed ring (325) when the fixed rod (321) moves, then rotating a rotating disc (221) from the outside to enable a rotating rod (222) to rotate, driving a second bevel gear (314) to rotate through a limiting shaft (311) and a first bevel gear (312) when the rotating rod (222) rotates, and enabling a fixing piece (316) to extend out of a sliding groove (219) through a threaded rod (315) to finally abut against the inner side of a machine tool guide rail (1) to realize installation;

s2: after the installation is finished, resetting the fixed rod (321) and then installing the friction plate (232) into the inner side of the installation plate (231), then installing a guide rail sliding block outside the machine tool guide rail (1), then rotating the rotating disc (221), driving the face gear (224) to rotate by the rotating disc (221) through the rotating rod (222) and the bevel gear (223), driving the worm wheel (2262) to rotate by the worm (2241) when the face gear (224) rotates, and increasing the distance between two groups of nut seats (2263) by the thread groove (2261) when the worm wheel (2262) rotates;

s3: with the increase of the interval between the nut seats (2263), the interval between the two groups of extrusion blocks (227) is increased, the compression block (228) is extruded by the extrusion blocks (227), and under the guidance of the fixed block (2252), the interval between the compression block (228) and the upper shell (211) and the lower shell (212) is increased, and the rotating disc (221) and the rotating rod (222) are fixed at the inner side of the machine tool guide rail (1) at the moment, so that under the action of the compression block (228), the mounting plate (231) and the friction plate (232) move outwards until the friction plate (232) abuts against the inner side of the guide rail slider, and when the friction plate (232) is worn, the friction plate (232) can be adjusted to be always attached to the guide rail slider, so that the whole using method is completed.
