摘要（英）：

The utility model relates to the field of instruments, and discloses an instrument pointer baffle shaft and a mounting structure thereof. The instrument pointer baffle shaft comprises a pointer, a baffle shaft, a scale panel, a mounting plate and adhesive. The baffle shaft, the scale panel and the pointer are arranged on the mounting plate. A countersink is drilled in one end of a through hole for mounting the baffle shaft on the mounting plate, and the countersink is filled with the adhesive. The baffle shaft is adhered on the mounting plate by using the adhesive in the countersink through drilling the countersink in one end of the through hole for mounting the baffle shaft on the mounting plate, the adhesive area of the baffle plate is enlarged, the mounting of the baffle shaft is more firm, the adhesive in the countersink shrinks during the drying process to tighten the baffle shaft, and the baffle shaft is further firmly fixed.
