[0010] As a further embodiment of the present invention, the lower mounting groove is formed by the outer ring body.

[0011] The utility model is beneficial in that it has a better sealing effect and improves the service life.

[0012] The six-dimensional force sensor has an integral sealed structure, which isolates the internal electronic components of the six-dimensional force sensor from the external environment, making the six-dimensional force sensor dust-proof and liquid-proof, greatly improving its service life in harsh environments with water vapor.
