[0006] Furthermore, a bottom slider is provided on the lower side of the slider connecting plate, and a silicone sleeve is installed on the outside of the grip force sensor.

[0007] Furthermore, the arm support is connected to the bearing cover plate by screws, and the bearing cover plate is connected to the bearing base by screws.

[0008] Furthermore, the multi-dimensional force sensor is connected to the bearing base by screws, and the threaded rod at the bottom of the grip force sensor is tightened into the threaded hole of the handle connector.

[0009] Furthermore, the deep groove ball bearing is embedded in the inner ring of the bearing base, and the bearing pressure ring and the bearing base are fixed to the slider connecting plate by fixing screws.

[0010] Furthermore, the arm support can be slidably adjusted along the extension end of the bearing cover plate to change its installation position.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of a handle connector, a multi-dimensional force sensor and a grip force sensor, allows the handle connector to combine and install the multi-dimensional force sensor and the grip force sensor.
