[0043] The height of the robotic arm drive unit can be increased by cylinder 18 to adapt to the height of the site.

[0044] Based on the above embodiments, such as Figure 1 and Figure 4 As shown, a first limit sensor 11 is provided on the top of the first support plate 4, and a sensor is provided on the bottom of the first support plate 4 to limit the minimum height of the robot arm drive unit to descend, thereby protecting the device.
