The material of the prior art grease nipple body 1 and the prior art grease nipple filling position 2 is cast iron / cast steel, and the assembly angle α of the prior art grease nipple body 1 and the prior art grease nipple filling position 2 can be selected as 0°, 45° and 90° according to the actual assembly position and the convenience of butter gun filling butter. In addition, the material of the prior art dustproof cap 3 is PE-M. Cast iron / cast steel, the corrosion resistance is much worse than brass, and in addition, the working condition of commercial vehicle is harsh, which can easily cause the grease nipple to corrode and cause its premature failure. The dustproof cap of the grease nipple is easy to fall off and cannot play a dustproof role. And it is very easy to be pulled out during maintenance, and basically cannot play a dustproof role, causing the grease nipple to be easily blocked and unable to fill butter during maintenance.
