Linear motor structure

The invention provides a linear motor structure which comprises a linear motor and an adjusting mechanism. The linear motor comprises an air cylinder and a piston arranged in the air cylinder in a sleeved mode. The adjusting mechanism comprises a connecting pipe, a first one-way valve and an adjusting valve; the cylinder and the first end of the piston form a back cavity, and the second end forms a compression cavity; the back cavity communicates with the compression cavity through a connecting pipe, an adjusting valve and a first one-way valve are arranged on the connecting pipe, and the first one-way valve is used for limiting gas to only flow towards the side with the large fluctuation pressure. According to the linear motor structure provided by the invention, the adjusting valve and the first one-way valve are arranged on the connecting pipe, so that when it is detected that the piston drifts or the pressure difference is formed between the compression cavity and the back cavity, it is ensured that gas i
