[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Those skilled in the art may make similar generalizations without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Example 1

[0025] like Figure 1 、 Figure 2 and Figure 5 As shown; a tool for removing a rack tube fastener nut provided in an embodiment includes a base 1, a support 2 is provided on one side of the top surface of the base 1, and a crossbar 5 is provided on the other side of the top surface of the base 1;

[0026] The support 2 is provided with a shaft 3 running through the top of the support 2, and a first fixing mechanism for locking the nut 63 is provided on one end of the shaft 3 facing the cross bar 5, and a second fixing mechanism for locking the nut 61 is provided on the side of the cross bar 5 facing the shaft 3. A vertical rod 51 is fixedly provided at the bottom of one end of the cross bar 5, and the bottom of the vertical rod 51 is rotatably connected to the top surface of the base 1;

[0027] The shaft 3 is driven to rotate by a driving device.

[0028] The first fixing mechanism is a sleeve 32 , which is coaxially fixed to one end of the shaft 3 . The internal channel cross-section of the sleeve 32 is hexagonal. The second fixing mechanism is a strip block 52 , on which a U-shaped groove 521 is provided.

[0029] A first pulley 31 is coaxially fixedly disposed on one end of the shaft 3 away from the first fixing mechanism;

[0030] The driving device is a motor 4 arranged on the top surface of the base 1. A second pulley 41 is coaxially fixedly arranged on the output shaft of the motor 4, and the two pulleys are driven by belts.

[0031] The height of the cross bar 5 is consistent with the height of the sleeve 32 .

[0032] When the utility model is in use;

[0033] First, rotate the crossbar 5 to be parallel to the shaft 3, insert the hexagonal nut 61 of the fastener 6 into the U-shaped groove 521, and rotate the crossbar 5 to Figure 1 In the position shown, the hexagonal nut 63 just extends into the sleeve 32. Hold the handle 7 and keep it still. At this time, start the drive motor 4 to drive the shaft 3 to rotate, and then rotate the sleeve 32 to unscrew the nut 63 from the screw 62. After completion, rotate and remove the cross bar 5, and then pull the nut 63 out of the sleeve 32. The wire with a hook can be used for pulling it out.

[0034] It should be noted that the internal channel size of the sleeve 32 is slightly larger than the nut 63, which facilitates the insertion and removal of the nut 63.

[0035] Example 2

[0036] The difference between this embodiment and the first embodiment lies in the difference between the first fixing mechanism and the second fixing structure;

[0037] Specifically, if Figure 3 and Figure 4 As shown, the first fixing mechanism is a sleeve 32, and an annular sink 33 is provided on the end face of the sleeve 32 away from the shaft 3. Six limit blocks 35 are fixed in a radial array on the sink 33. A sliding groove is provided on the side of the limit block 35 away from the sink 33 along the radial direction of the shaft 3. A limit rod 36 is slidably provided in the sliding groove. A transmission rod 361 is provided on the side of the limit rod 36 away from the sink 33. The transmission rod 361 is parallel to the shaft 3. A plurality of positioning screw holes 34 are arranged in a circumferential array on the end face of the sleeve 32 away from the shaft 3.

[0038] An annular cover plate 37 is provided at one end of the sleeve 32 away from the shaft 3. The annular cover plate 37 has six obliquely arranged strip-shaped through holes 371 arranged in a circumferential array. A radius line passing through the center of the strip-shaped through hole 371 of the annular cover plate 37 forms an acute angle with the strip-shaped through hole 371, preferably an angle of 45 degrees. The six transmission rods 361 are respectively slidably disposed in the six strip-shaped through holes 371. A plurality of avoidance holes 372 are provided on the outer edge of the annular cover plate 37.

[0039] By rotating the cover plate 37, the limiting rod 36 can be moved closer to or away from the axis of the sleeve 32, thereby adapting to hexagonal nuts 63 of different sizes. When the limiting rod 36 is adjusted, it is fixed by screwing through the avoidance hole 372 and threading it into the positioning screw hole 34.

[0040] The second fixing mechanism includes two threaded rods 55 and a horizontal base plate 56. The base plate 56 is fixedly arranged at the lower part of the cross bar 5 facing the sleeve 32. A horizontal lower clamping plate 54 and an upper clamping plate 53 are sequentially arranged above the base plate 56. The bottoms of the two threaded rods 55 are rotatably connected to the base plate 56. The threaded rods 55 are threadedly connected to the screw holes of the upper clamping plate 53 and the screw holes of the lower clamping plate 54. The thread directions of the screw holes of the upper clamping plate 53 and the screw holes of the lower clamping plate 54 are opposite.

[0041] During use, the distance between the upper clamping plate 53 and the lower clamping plate 54 is adjusted by rotating the threaded rod 53 so that the distance between the two clamping plates is adapted to hexagonal nuts 61 of different sizes.

[0042] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort shall fall within the scope of protection of the present invention.
