[0038] In summary, referring to Figure 10 , under normal conditions, a plurality of support units 3 are evenly distributed below the lead screw 4, and the top end of each support unit 3 provides support for the lead screw 4, at this time the support range of the support unit 3 is the whole of the lead screw 4, that is, the long support area 9, thereby increasing the number of support and constraint points on the lead screw 4, thereby increasing the overall weight-bearing capacity of the lead screw 4, so that the lead screw 4 can support the sliding table 5 to move linearly under a heavier load, and these points can provide additional damping, and the support unit 3 can also absorb and dissipate the energy of the lead screw 4 vibration through the energy-absorbing hammer 36, and the plurality of support units 3 divide the longer lead screw 4 into a plurality of shorter short sections 8, the shorter short sections 8 increase the equivalent stiffness of the lead screw 4, and under the same stress, the deformation of the shorter short sections 8 will be relatively smaller, thereby effectively preventing the lead screw 4 from bending due to a heavy load, ensuring the linear transmission accuracy of the lead screw 4 and prolonging its service life.

[0039] Wherein, referring to Figures 7 to 9 , the adjusting unit 7 comprises a wheel disc one 71 fixedly connected with the lead screw 4, a plurality of groups of the poking block 72 circumferentially and equally arranged on the wheel disc one 71, a soft spring 73 arranged at the end of each group of the poking block 72, a wheel disc two 74 located below the wheel disc one 71 and through the shaft center of the wheel disc two 74, a stop block 75 arranged on the side of the wheel disc two 74 and in a triangular structure, the poking block 72 can rotate with the lead screw 4, the wheel disc one 71 rotates and will throw the poking block 72 outwards under the action of centrifugal force, and the soft spring 73 reversely pulls the poking block 72 through the elastic contraction of itself, thereby limiting the length of the poking block 72 extending outwards, the faster the speed of the lead screw 4 rotates, the greater the centrifugal force the poking block 72 receives, and the centrifugal force applied at different speeds will overcome the elastic contraction force of the soft spring 73 to different degrees, so that the poking block 72 extends outwards to different lengths at different speeds of the lead screw 4.
[0040] Further, referring to Figures 7 to 9 , the outermost end of the poking block 72 is provided with a cross section matched with the stop block 75, and the inclined surface is provided with a tooth, the inclined side of the stop block 75 is provided with a tooth groove, and the amplitude of the inclined side of the stop block 75 expands outward from top to bottom, the wheel disc one 71 is provided with a containing groove 711 containing the poking block 72, the poking block 72 is contracted in the containing groove 711 by the pulling of the soft spring 73 in the normal state, the outer end of the poking block 72 is provided with a counterweight 721, the counterweight 721 makes the center of the poking block 72 at the end thereof, thereby better matching the influence of centrifugal force, the counterweight 721 can be added according to the size of the centrifugal force, thereby ensuring that the centrifugal force can normally act on the poking block 72, the poking block 72 can apply the force to the poking adjusting unit 2 through the cooperation of the tooth on the outer end inclined surface and the tooth groove on the inclined side of the stop block 75, the contact position of the poking block 72 and the inclined side of the stop block 75 directly affects the amplitude of the poking adjusting unit 2, the lower the position of the poking block 72 and the inclined side of the stop block 75 contacted, the greater the amplitude of the poking adjusting unit 2 rotated.
[0041] Further, referring to Figures 7 to 9 , the adjusting unit 7 further comprises a connecting block 77 connected with the outermost end of the adjusting unit 2, and a hydraulic reset rod 76 rotationally connected to the outer end of the connecting block 77, and the hydraulic reset rod 76 is arranged obliquely as a whole, and the outer end of the hydraulic reset rod 76 is rotationally connected with the base 1, the hydraulic reset rod 76 is a mature hydraulic telescopic rod in the prior art, which can extend outwards when subjected to external force, and will slowly retract when the external force disappears, so that when the adjusting unit 2 is driven to rotate by a certain angle by the adjusting unit 7, the connecting block 77 will synchronously drive the extension part of the hydraulic reset rod 76, and when the rotating speed of the lead screw 4 decreases, the adjusting unit 7 no longer continuously applies the poking force to the adjusting unit 2, the hydraulic reset rod 76 will drive the adjusting unit 2 to reset by contraction.
[0042] In use, in combination Figures 7 to 9 When the rotation speed of the lead screw 4 is increased, the centrifugal force exerted by the wheel disc 1 71 on the block 72 is also increased. The greater centrifugal force will cause the block 72 to extend outwardly to a greater length against the soft spring 73. The block 72 of the greater length will contact the bevel of the block 75 at the lower and outer part, thereby pushing the wheel disc 2 74 to drive the adjustment unit 2 to rotate greatly. The adjustment unit 2 of the great rotation will drive the plurality of support units 3 to move greatly towards the middle position of the lead screw 4, thereby causing the plurality of support units 3 to concentrate at the middle position of the lead screw 4 (as shown in Figure 11 The support range of the support unit 3 is adjusted from the long support area 9 to the concentrated support area 10 for supporting the middle part of the lead screw 4. The middle part of the lead screw 4 is closer to the middle position because the constraint is relatively weak due to the greater distance from the two end support points, the centrifugal force is significantly increased, the vibration frequency and amplitude of the middle part of the lead screw 4 are increased. The plurality of support units 3 concentrate the support range to the middle part of the lead screw 4 through the adjustment unit 7, thereby effectively strengthening the energy absorption and vibration suppression effect of the middle part of the lead screw 4, achieving the targeted support operation, and effectively ensuring the transmission accuracy of the linear module. The amplitude of the driven adjustment unit 2, i.e. the amplitude of the adjustment unit 2 driving the support unit 3 to adjust, i.e. the size of the adjustment range of the support unit 3, is affected by the extension length of the block 72. The extension length of the block 72 is directly matched with the rotation speed of the lead screw 4. Therefore, the adjustment unit 7 can follow the rotation speed of the lead screw 4 to drive the adjustment unit 2 to adjust the position of the plurality of support units 3 and the overall distribution range of the plurality of support units 3 in a proportional manner, thereby further strengthening the energy absorption and vibration suppression effect of the lead screw 4 and further ensuring the transmission accuracy of the linear module.
