The grinding structure includes a grinding head and a transmission assembly. The grinding head is rotatably connected to the output end of the transmission assembly for grinding operations. The telescopic structure 1 is adjustable in length and is sleeved on a portion of the transmission assembly. A gripping portion is provided at the first end of the telescopic structure 1. The grinding head abuts against the second end of the telescopic structure 1. The operator adjusts the telescopic structure 1 to a suitable length, and then holds the gripping portion at the first end of the telescopic structure 1, so that the grinding head abutting against the second end of the telescopic structure 1 can contact the steel plate to be ground, so as to facilitate grinding of high steel plates without the need to set up scaffolding or use a climbing platform, etc., which is conducive to improving the efficiency of the grinding operation and can be used for grinding operations in narrow spaces.

[0031] Specifically, the grinding head is an existing structure that has been disclosed in the prior art. Its specific structure and principle refer to the prior art and will not be repeated here.

[0032] Optionally, the transmission assembly includes an air supply pipe and a driving mechanism. The air supply pipe is inserted into the telescopic structure 1 for delivering compressed air. The air supply pipe is connected to the air inlet of the driving mechanism, and the grinding head is rotatably connected to the output end of the driving mechanism. Compressed air is delivered into the driving mechanism through the air supply pipe. The driving mechanism can convert the kinetic energy of the compressed air into mechanical energy, thereby driving the grinding head to rotate to grind the steel plate. Specifically, the driving mechanism is a pneumatic motor commonly used in the art. Its specific structure and principle refer to the prior art and are not described here.

[0033] Furthermore, a regulating valve is provided on the air supply pipe, and the regulating valve is used to adjust the air volume in the air supply pipe to adjust the air volume entering the driving mechanism, thereby controlling the rotation speed or frequency of the grinding head and adjusting the grinding effect.

[0039] Optionally, an anti-corrosion layer is provided on the outer surface of each connecting pipe 11 to further improve the anti-corrosion performance of the connecting pipe 11 and extend the service life of the telescopic structure 1. Specifically, the specific composition of the anti-corrosion layer refers to the prior art and will not be repeated here.

[0040] Alternatively, the surface of each connecting pipe 11 is treated, such as anodizing or painting, which can not only improve the appearance of the connecting pipe 11, but also enhance its corrosion resistance and wear resistance.
