A fracture-resistant ceramic glow plug
By incorporating a combination of a calibration guard plate and a push bolt into the ceramic glow plug, the problem of ceramic glow plugs being prone to breakage due to vibration is solved, resulting in better shock resistance.

Abstract
This utility model relates to the field of ceramic glow plug technology, specifically a fracture-resistant ceramic glow plug, comprising an adapter component, a clamping component disposed outside the adapter component, a protective component installed outside the clamping component, and four positioning bolts installed inside the adapter component and the protective component; the clamping component includes an adapter, an electrode installed inside the adapter, and a ceramic heating tube installed at the bottom of the electrode. By leaving a sufficiently large cylindrical gap between the conventional ceramic heating tube and the outer shell, and arranging multiple evenly distributed calibration plates within the cylindrical gap, as the push bolt pushes the sliding pad upward, the multiple traction plates pulled by the sliding pad will cause the evenly distributed calibration plates to centrally pressurize the ceramic heating tube, actively applying buffer protection to the ceramic heating tube, thereby reducing the risk of heating tube breakage due to vibration imbalance.
