Vertical displacement stopping system

A vertical displacement stopping system, comprising a sliding guide mechanism, a locking mechanism and a bearing mechanism, wherein:

• the locking mechanism, having positioning holes, comprises positioning pins, telescopic mechanisms, and a handle located at a front portion of the bearing mechanism, wherein the handle is connected with the positioning pins through transmission parts, respectively;
• each of the telescopic mechanisms comprises a housing having a chamber, a movable block located within the chamber, and a reset spring located between a top portion of the movable block and the housing, wherein each of the transmission parts is connected with each of the positioning pins through the movable block;
• the handle is slidably connected with a bottom of the bearing mechanism, the housing is located at a bottom end of the bearing mechanism, each of the housing and the bearing mechanism has a through-hole for allowing the each of the positioning pins to pass through;
• the movable block is connected with a guide rod, the reset spring is sleeved outside the guide rod, the housing has another through-hole for allowing the guide rod to pass through;
• the sliding guide mechanism comprises moving rails and fixed rails, wherein the moving rails are connected with the bearing mechanism;
• the bearing mechanism comprises a support part which is connected with the fixed rails and a bearing device for accommodating an object;
• T-shaped connectors are provided at two sides of an end of the bearing device;
• each of the T-shaped connectors comprises a clamping arm protruding from the end of the bearing device and a connecting arm located at a front end of the clamping arm;
• the support part has multiple mounting holes at two sides thereof;
• each of the mounting holes comprises a penetration hole, a connection hole and a clamping hole, wherein a length of the penetration hole is larger than or equal to a length of the clamping arm, a total length of the connection hole and the clamping hole is larger than or equal to a length of the connecting arm, and smaller than the length of the clamping arm.
