It should be understood that the specific embodiments described herein are only for explaining and understanding the present utility model, and do not limit the present utility model.

[0026] In the present utility model, unless otherwise stated, the directional terms such as "upper, lower, inner, outer" included in the terms only represent the orientation of the terms in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0027] As Figures 1-4 shown, a wire winding frame of a pulse modulator includes: a fixed side plate 1, a central support tube 2 fixedly connected coaxially with the fixed side plate 1, a movable side plate 3 detachably assembled coaxially on the central support tube 2 away from the fixed side plate 1, and at least three support rods evenly distributed along the central support tube 2;

[0028] The support rod includes a first support rod 4 parallel to the central support tube 2 and with an adjustable distance from the central support tube 2, a second support rod 6 connected to the end of the first support rod 4 away from the fixed side plate 1 through a first flexible connection part 5, and a positioning rod 8 connected to the second support rod 6 away from the first flexible connection part 5 through a second flexible connection part 7 and adjustably connected to the central support tube 2.

[0029] When manufacturing the support rod, the cross-sectional areas of the first flexible connection part 5 and the second flexible connection part 7 can be made smaller than those of the first support rod 4 and the second support rod 6, that is, the first flexible connection part 5 and the second flexible connection part 7 can be bent. The support rod is an integral whole, which is simple to manufacture, low in cost, and easy to assemble.

[0030] The second support rod 6 can provide a supporting force for the end of the first support rod 4 away from the fixed side plate 1, improving the compressive resistance of the first support rod 4; when adjusting the distance between the first support rod 4 and the central support tube 2, the positioning rod 8 also needs to be separated from the central support tube 2, and when the position adjustment of the first support rod 4 is completed, the positioning rod 8 is connected to the central support tube 2 again.

[0031] A threaded rod 9 with the same length direction and a diameter smaller than that of the first support rod 4 is fixedly connected to the end of the first support rod 4 away from the first flexible connection part 5. An installation through hole 10 matching the corresponding threaded rod 9 is penetratingly provided on the fixed side plate 1. A plurality of installation through holes 10 are arranged at intervals in the radial direction of the fixed side plate 1. A first nut 11 that can abut against the side of the fixed side plate 1 away from the movable side plate 3 is detachably sleeved on the threaded rod 9.

[0032] When it is necessary to adjust the position of the first support rod 4 on the fixed side plate 1, the first nut 11 is loosened and removed, the threaded rod 9 is pulled out from the corresponding installation through hole 10, then the threaded rod 9 is inserted into another installation through hole 10, and the first nut 11 is tightened on the threaded rod 9 again, and the position adjustment of the first support rod 4 is completed.

[0033] An insertion rod part 12 with a diameter smaller than that of the positioning rod 8 is connected to the end of the positioning rod 8 away from the second flexible connection part 7. A plurality of first positioning insertion holes 13 matching the corresponding insertion rod part 12 are penetratingly provided on the central support tube 2. A plurality of first positioning insertion holes 13 are arranged at intervals along the axial direction of the central support tube 2.

[0034] Before adjusting the position of the first support rod 4, the insertion rod part 12 is pulled out from the corresponding first positioning insertion hole 13; when the distance adjustment between the first support rod 4 and the central support tube 2 is completed, the insertion rod part 12 is inserted into the corresponding first positioning insertion hole 13.

[0035] A sleeve portion 14 that can be sleeved on the central support tube 2 is fixedly connected to the movable edge plate 3 coaxially, and a positioning bolt 15 for fixing the sleeve portion 14 is threadedly connected to the sleeve portion 14.

[0036] By loosening the positioning bolt 15, the movable edge plate 3 can be removed from the central support tube 2, facilitating the adjustment of the distance between the first support rod 4 and the central support tube 2.

[0037] A second positioning jack for the positioning bolt 15 to pass through is provided through the central support tube 2.

[0038] The positioning bolt 15 can directly abut against the outside of the central support tube 2. However, after the second positioning jack is opened, the positioning bolt 15 can be directly inserted into the second positioning jack, which can improve the installation stability of the movable edge plate 3.

[0039] An end cover portion 16 is provided at the end of the central support tube 2 close to the fixed edge plate 1. An installation bolt 17 passing through the end cover portion 16 is inserted into the fixed edge plate 1, and a second nut 18 that can abut against the side of the end cover portion 16 away from the fixed edge plate 1 is threadedly connected to the installation bolt 17.

[0040] During assembly, the central support tube 2 and the fixed edge plate 1 can be connected together through the installation bolt 17 and the second nut 18.

[0041] A positioning card slot for the second nut 18 to be inserted into is recessed on the side of the end cover portion 16 away from the fixed edge plate 1.

[0042] Inserting the second nut 18 into the positioning card slot can limit the rotation of the second nut 18, facilitating the rotation of the installation bolt 17 to connect the central support tube 2 and the fixed edge plate 1 together.
