Prior art, for example, patent number CN 216918437U discloses a novel matrix lifting device comprising a base with an outer rod at its upper end, an inner rod within the outer rod, and a drive mechanism connected to the inner rod. The drive mechanism comprises a lead screw motor at the lower end of the base and a lead screw ring connected to the lower end of the inner rod. Driven by the drive mechanism, the inner rod performs linear reciprocating motion within the outer rod, thereby avoiding mechanical friction and reducing noise during movement.

[0003] However, existing matrix-type lifting support devices present the following challenges during use: When supporting an object, the inner rod's overall force is solely dependent on the threaded connection with the lead screw, lacking a decentralized support structure. This can lead to insufficient support and slippage over extended periods of use or as the lead screw wears, compromising overall support safety. Therefore, a corresponding technical solution is needed to address these issues. Utility Model Content

[0025] Further improved, the fastening member 10 includes a rotating base and a fixing block, the rotating base is fixedly mounted on the bottom of the screw ring 9, the fixing block is rotatably connected to the rotating base, and a torsion spring is installed at the connected position of the fixing block and the rotating base. Specifically, the torsion spring can push the fixing block to move in a certain direction, thereby ensuring that the end of the fixing block is always in contact with the rotating rod 1, ensuring that the end of the fixing block can be clamped in the fiber slot 7, and one end of the fixing block is located on the limit slot 7.

[0026] Further improved, the adjusting member 12 is composed of two bevel gears and an adjusting rod. The two bevel gears are respectively installed on the rotating rod 1 and the adjusting rod. The cross-section of the adjusting rod is a "T"-shaped structure. One end of the adjusting rod is located outside the outer rod 2, and the adjusting rod is rotationally connected to the outer rod 2.

[0027] When the lever 1 is in the proper position, the adjusting rod 8 is rotated, and the meshing connection of the bevel gear 1 is cooperated with the adjusting rod 8 to drive the rotating rod 1 to rotate, so that the end of the locking block moves into the limiting slot 7. Then, the driving motor 13 slightly drives the screw rod 8 to rotate in the opposite direction, so that the inner rod 3 is slightly contracted to a certain position, and the end of the locking block can be firmly stuck in the limiting slot 7.

When used for a long time or after the screw rod is worn, it is very easy for the inner rod to have insufficient supporting force and slip, which affects the overall support safety. Technical problem: Through the mutual combination of the above-mentioned components, the present invention, such as the limit slot 7 and the clamping piece 10, can conveniently fix the position of the inner rod 3. When the inner rod 3 moves to the appropriate position, the adjusting rod is rotated, and the meshing connection of the bevel gear is cooperated with to drive the rotating rod 1 to rotate, so that the end of the clamping block moves into the limit slot 7. Subsequently, the driving motor 13 slightly drives the screw rod 8 to rotate in the opposite direction, so that the inner rod 3 slightly contracts a certain distance, so that the end of the clamping block can be firmly clamped in the limit slot 7. When the inner rod 3 is supported as a whole, its supporting force can be dispersed between the clamping block and the limit slot 7, so as to avoid excessive force on the screw rod 8 and reduce its wear. In addition, the clamping block and the limit slot 7 can lock the position of the inner rod 3 to avoid sliding.
