[0002] A CNC grinder is a machine tool that uses a grinding tool through CNC technology to grind the surface of a workpiece. When in use, the existing CNC grinder frame shell lacks a convenient threading structure for the CNC mold circuit. The random arrangement of the circuits can easily lead to entanglement between the circuits, affecting the operation and use of the device. A CNC grinder frame shell with application number CN2021211388302 includes a main shell, and connecting shells are plugged into both sides of one side of the main shell. The main shell and the connecting shell are installed and connected by plugging in the plug-in groove and the plug-in strip, which adds a convenient installation feature to the device, thereby facilitating the disassembly, replacement and maintenance of some structures.

[0003] Although the device has the above advantages, during use, the device arranges the wires through the limiting holes and the limiting clamps, which has the following defects. First, there is a gap between the limiting clamps and the limiting holes, and there are gaps between the redundant connection holes on each connecting shell, which easily causes internal dust contamination. Secondly, the curvature of the limiting clamp is fixed, and when clamping wires of different thicknesses, the clamping is prone to unstable clamping, and the clamping is performed by spring expansion and contraction, which further reduces the stability of the wires. Therefore, it is necessary to solve the problems that still exist in the prior art. Utility Model Content
