[0033] like Figure 1-4 As shown, the utility model provides a fixing member for a leaf spring, comprising two locking tube groups 1 and two limiting plates 2, wherein the cross bars of the two locking tube groups 1 are provided with guide holes 11 penetrating in the transverse direction, a guide screw 12 is slidably connected in the guide hole 11, and a transverse nut 13 is threadedly connected to the guide screw 12;
[0034] Two locking tube groups 1 connect the two limit plates 2. Two side adjustment holes 31 that penetrate vertically are opened at the ends of the two limit plates 2 that are close to each other. The two ends of one locking tube group 1 are respectively slidably connected in the side adjustment holes 31 of the two limit plates 2. The locking tube groups 1 are all threadedly connected with vertical nuts 14.
[0035] An adjusting mechanism for adjusting the width of the locking tube set 1 is provided between the two limiting plates 2. The adjusting mechanism includes an adjusting hole 21 extending transversely through the middle of the two limiting plates 2. An adjusting screw 22 is threadedly connected in each of the two adjusting holes 21. An adjusting column 20 is fixedly installed at the ends of the adjusting screws 22 that are away from each other.
[0036] One end of the two adjusting screws 22 close to each other is rotatably connected to a positioning rod 23 , one end of the positioning rod 23 is fixedly mounted with an axle seat 24 with an arc-shaped abutment surface, and the other end of the positioning rod 23 is fixedly mounted with a leaf spring seat 25 .

[0038] Optionally, in the above technical solution, vertical slideways 41 are provided on opposite side walls of the leaf spring seat 25 , and limit blocks 42 are slidably connected in the slideways 41 , and the ends of the limit blocks 42 close to each other are fixedly connected to the clamping plate 43 .
[0039] Optionally, in the above technical solution, one end of the leaf spring seat 25 away from the positioning rod 23 is connected to the auxiliary plate 44 by bolts, and a threaded hole is opened in the middle of the auxiliary plate 44.
[0040] Optionally, in the above technical solution, one end of a driving screw 45 is threadedly connected to the threaded hole, and the other end of the driving screw 45 is fixedly connected to the middle of the clamping plate 43 , and a gasket 46 is fixedly installed on one side of the clamping plate 43 away from the auxiliary plate 44 .
[0041] Optionally, in the above technical solution, the outer peripheral sleeve of the locking tube group 1 is provided with two anti-slip sleeves 10 , and the anti-slip sleeves 10 abut against the limiting plate 2 .
[0042] The threads of the two adjusting screws 22 are arranged in opposite directions and have the same length, so that they can be adjusted synchronously, and the two adjusting screws 22 keep the position of the limiting plate 2 symmetrical;
[0043] The side wall width of the leaf spring seat 25 gradually increases from one end close to the positioning rod 23 to the end far away from the positioning rod 23;
[0044] The diameters of the adjustment column 20 and the positioning rod 23 are both larger than the diameter of the adjustment hole 21;
[0045] The positioning rods 23 limit the distance that the limiting plates 2 approach each other, and the adjusting columns 20 limit the distance that the limiting plates 2 move away from each other.
[0046] Working principle:
[0047] When in use, first place the leaf spring in the leaf spring seat 25, rotate the drive screw 45 to make the clamping plate 43 close to the leaf spring, until the middle of the leaf spring is clamped by the leaf spring seat 25 and the clamping plate 43 at the same time, and then place the leaf spring and the device as a whole on the axle;
[0048] First, remove the guide screw 12 and the transverse nut 13 from the locking tube assembly 1, and turn the adjustment column 20 clockwise. Since the positioning rod 23 is fixed, the adjustment screws 22 on both sides rotate in place, driving the two limit plates 2 to move away from each other;
[0049] At this time, the locking tube set 1 is sleeved on the outer periphery of the axle, and the guide screw 12 is first passed through the guide hole 11 and the transverse nut 13, and the adjustment column 20 is turned counterclockwise to drive the two limit plates 2 to move closer to each other until the vertical rod of the locking tube set 1 abuts against the axle to clamp the axle laterally, and then the transverse nut 13 is turned to a position close to the locking tube set 1 to position the transverse clamping of the axle;
[0050] Finally, slide the vertical rod of the locking tube set 1 into the side adjustment hole 31 of the limit plate 2 to a suitable position, so that the cross rod of the locking tube set 1 and the axle seat 24 can vertically clamp the axle, and at this time, screw the vertical nut 14 to a position close to the limit plate 2.
[0051] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
