DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0027] Embodiment 1

[0028] AsFigures 1 to 3 As shown, a tool clamp of a stainless steel hanging basket of a centrifuge comprises a first fixed frame 1, the first fixed frame 1 is a right-opened U-shaped structure, two second round holes 11 corresponding to two first round holes 22 of the stainless steel hanging basket 2 are embedded in the upper side horizontal plate part of the first fixed frame 1, and a vertical column 3 vertically penetrating the second round holes 11 is used to limit the stainless steel hanging basket 2 horizontally. A screw hole 12 (blind hole) is arranged at the center position of the upper and lower horizontal plate parts of the first fixed frame 1, and vertical first through holes 13 are arranged on the upper and lower horizontal plate parts of the first fixed frame 1 on the front and back sides of the screw hole 12. The first fixed frame 1 is slidingly embedded in a front-opened second fixed frame 4, the second fixed frame 4 is a side-opened U-shaped structure, the upper and lower horizontal plate parts of the second fixed frame 4 on the outer side (upper side and lower side) of the screw hole 12 are respectively provided with second through holes 41 vertically coinciding with the screw hole 12, and bolts 42 cooperating with the screw hole 12 are penetrating the second through holes 41. The upper and lower horizontal plate parts of the second fixed frame 4 on the front side of the second through hole 41 are respectively provided with third through holes 43 with the same diameter as the first through hole 13 and vertically coinciding with the first through hole 13, and a pin shaft 44 slidingly cooperating with the first through hole 13 is slidingly penetrating the third through hole 43 on the upper side downward. A fixed seat 5 is fixedly arranged on the rear side surface of the second fixed frame 4, and the fixed seat is a cylinder in the front-rear direction. A magnetic block 45 attracting the pin shaft 44 is fixedly arranged at the outer end of the third through hole 43. The pin shaft 44 is prevented from slipping off.

[0029] The top of the vertical column 3 is below the upper end of the second round hole 11, and an arc-shaped handle 31 is fixedly arranged at the top of the vertical column 3.

[0030] The top surface of the arc-shaped handle 31 is flush with the upper end of the second round hole 11. The inner surface of the upper side horizontal plate part of the second fixed frame 4 abuts against the arc-shaped handle 31, which is beneficial to the firmness of the vertical column 3 and avoids the vertical column 3 moving up and down.

[0031] The upper and lower outer surfaces of the first fixed frame 1 slidingly cooperate with the upper and lower inner surfaces of the second fixed frame 4. This is beneficial to limiting the first fixed frame 1 upward and downward.

[0032] The first round hole 22 and the second round hole 11 have the same diameter.

[0033] The side peripheral surface of the vertical column 3 slidingly cooperates with the inner surface of the second round hole 11, and the side peripheral surface of the vertical column 3 slidingly cooperates with the inner surface of the first round hole 22.

[0034] In use, the stainless steel hanging basket 2 is transversely slid into the first fixing frame 1 to limit the vertical position of the stainless steel hanging basket 2, then the vertical column 3 is inserted into the second round hole 11 and the first round hole 22 from top to bottom to limit the transverse position of the stainless steel hanging basket 2. Then the first fixing frame 1 is slid into the second fixing frame 4, the bolt 42 is connected with the screw hole 12 through the second through hole 41 to fix the first fixing frame 1, and the first fixing frame 1 can be adjusted in angle when the bolt 42 is not tightened or loosened, the pin shaft 44 is inserted into the third through hole 43 and the first through hole 13 to position the first fixing frame 1 and avoid rotation, so that one ear 21 is exposed on the front side, when the ear 21 is processed, the pin shaft 44 is pulled out, the first fixing frame 1 is rotated, the other ear 21 is turned out, then the pin shaft 44 is positioned, so that the effect of changing the ear 21 without disassembling the stainless steel hanging basket 2 is realized. The fixing seat 5 can be clamped on the three-jaw chuck of the numerical control lathe to process the ear 21 of the stainless steel hanging basket 2, and the magnetic block 45 can prevent the pin shaft 44 from slipping off.

[0035] It is worth noting that the second round hole 11 needs to be upward when the first fixing frame 1 fixes the stainless steel hanging basket 2, and the second fixing frame 4 is symmetrical in structure and does not distinguish between front and back.

[0036] The pin shaft 44 can be used only (or another one can be inserted at the bottom, and the fixing effect is better). There is one bolt 42 above and one below. When the stainless steel hanging basket 2 is disassembled, the pin shaft 44 is pulled out first, then the upper and lower bolts 42 are disassembled, then the first fixing frame 1 is slid out, then the vertical column 3 is taken out, and finally the stainless steel hanging basket 2 can be pulled out to one side transversely.
