Abstract: A pluggable optical module unlocking structure has a shell and outer buckle; a mounting groove with a metal rocker plate having a flat and oblique rocker plates; the oblique rocker plate at a flat rocker plate end away from the outer buckle, and an oblique rocker plate end near the flat rocker plate is a lower end; a flat rocker plate end away from the oblique rocker plate symmetrically has lifting claws on both sides of the outer buckle; a pulling tab is slidably mounted on the shell, the pulling tab includes a pressing rod in a shell width direction, and a lower end pressing rod surface abuts against a flat rocker plate upper end surface. The pressing rod and metal rocker plate form a seesaw structure unlocking mechanism. The pulling tab moves the pressing rod so that the lifting claws raise the cage spring upward to unlock.

Abstract: A robotic drilling apparatus is described which has been adapted for drilling holes in ceilings and walls on a construction site. The apparatus (100) comprises a robotic arm (110) mounted to a substructure (112), the substructure comprising a lifting mechanism arranged to lift the robotic arm to a working position, wherein the robotic arm has a base end (110a) and a movable end (110b), the base end being mounted to an upper surface (114) of the lifting mechanism and the movable end being capable of movement with respect to the base end in a three dimensional space, wherein the robotic drilling apparatus further comprises a mount (120) provided on the movable end for holding a drilling device (122) and a control unit (134) for controlling the operation of the robotic arm. The lifting mechanism preferably comprises a scissor-jack lifting platform. The robotic arm (110) and any support structure (134) for the robotic arm weighs less than 43 kg, and preferably individually weigh less than 23 kg.
