  • Figure 6 shows a structural view of a nut clamp 600 of another embodiment of the present application.
  • the embodiment shown in Figure 6 is similar to that of the embodiment shown in Figure 1 except that the first biasing arm 613 and the second biasing arm (covered up in Figure 6) and the first release operation portion 616 and the second release operation portion (covered up in Figure 6) are different from those in the first embodiment.
  • the second biasing arm and the second release operation portion have the same structure as the first biasing arm 613 and the first release operation portion 616, respectively.
  • neither the upper portion of the first biasing arm 613 nor the upper portion of the second biasing arm is provided with a bifurcation of a U-shaped structure; thus, the upper portion of the first biasing arm 613 and the upper portion of the second biasing arm respectively have only one abutting end for engaging with the lower surface of the panel.
  • the first release operation portion 616 and the second release operation portion are still arm-shaped structures extending inward and upward from upper portions of the first biasing arm 613 and the second biasing arm. However, they also bend inwardly while extending inwardly from the upper portions of the first biasing arm 613 and the second biasing arm.
  • the base plate 602 is further provided with holding protrusions 621, 622, 623, and 624.
  • the holding protrusions 621, 622, 623, and 624 extend outward from the first side 145 and the second side 147, respectively, and are located in the hollow portions of the first holding arm 610 and the second holding arm 620. After insertion of the nut clamp 600 into the hole 211 of the panel 210, the holding protrusions 621, 622, 623, and 624 are located above the panel.
  • the protrusions 601, 602, 603, and 604 are kept cooperating with the first biasing arm 613 and the second biasing arm to better retain the nut clamp 600 on the panel.
  • the nut clamp 100 of the embodiment shown in Figure 1 may also be provided a similar holding protrusion portion.
  • Figure 7 shows a structure of a nut clamp 700 according to a further embodiment of the present application with a bolt 320 therein.
  • the embodiment shown in Figure 7 is similar to that of the embodiment shown in Figure 1 except that the first biasing arm 713 and the second biasing arm (covered up in Figure 6) and the first release operation portion 716 and the second release operation portion (covered up in Figure 6) are different from those in the first embodiment.
  • the second biasing arm and the second release operation portion have the same structure as the first biasing arm 713 and the first release operation portion 716, respectively.
  • the upper portion of the first biasing arm 713 and the upper portion of the second biasing arm are not provided with a bifurcation of the U-shaped structure.
  • the first release operation portion 716 and the second release operation portion are not arm-shaped structures, but notches formed extending inwardly at the upper portion of the first biasing arm 713 and the upper portion of the second biasing arm, respectively.
  • the first release operation portion 718 and the second release operation portion 725 are located below the panel.
  • the notch shapes of the first release operation portion 716 and the second release operation portion can be seen through the through hole above the panel.
  • the nut clamp of the present application makes it not only easy to install, but also can be more firmly held in the panel, so that it is more conducive to adjusting the screwing depth of the bolt in the nut clamp for adjusting the length of the nut clamp assembly.
  • the nut clamp of the present application is also designed to be conveniently detached from the panel when needed, and the mounting panel will not be damaged when disassembled.
  • a nut clamp of the present application has a simple and compact structure and is easy to be integrally formed. Therefore, it can facilitate industrial production and reduce production costs.
