Optical system setup, microscopic observation, fiber coupling, sample alignment, many compact optical path scenarios, do not require long-stroke scissor-type structures, but have very high requirements for the coaxiality of the lifting, lateral shaking, and repeated positioning. The traditional scissor-type lifting mechanism is prone to lateral gaps, and in small-stroke high-precision alignment, slight swaying can affect the alignment effect of the optical path. The 7SVM0313 direct-action lifting platform adopts a direct-guide structure, eliminating the lateral offset隐患 of the scissor structure， and is specifically designed for short-stroke， high coaxiality vertical precision adjustment.

It uses a precise linear guide pair + lead screw drive scheme， with the lifting process moving linearly along the vertical axis， the movement trajectory is upright， and the lateral creep is extremely small. The effective lifting travel is 13mm， precisely matching the slight height fine-tuning requirements， with a 0.01mm adjustment resolution. The handwheel rotation feels uniform and delicate， without jamming or false position， the coarse adjustment is fast and in place， the fine adjustment is delicate and controllable， suitable for lens， probe， micro samples， photoelectric receiving elements' micrometer-level height calibration.

Rigidity and stability are the core advantages of the direct-action lifting platform. The integrated base structure has a precisely machined guide gap， and the lifting does not tilt or sway under the rated load. The locking mechanism locks quickly after reaching the position， the locking is reliable， has strong anti-vibration ability， and does not cause position drift during long-term static experiments， avoiding optical path drift and marking failure， significantly reducing the workload of repeated calibration， and ensuring the stability of calibration， imaging， and coupling test data.

Installation continues the universal design of the optical machine module， the tabletop and the base plate are reserved with standard optical installation holes， both up and down can be used as installation benchmarks. It can directly be equipped with sample holders， lens brackets， fiber clamps， and can also be combined with translation tables， rotation tables for stacking， to build a multi-degree-of-freedom fine-tuning platform， suitable for optical platforms， optical breadboards， etc. The body is compact and small， can be embedded in cramped integrated optical paths and small detection workstations， without occupying too much experimental table space.

The application scenarios are rich and widely used in university research laboratories， optical research workshops： microscopic focusing debugging， fiber optical path coupling， optical element calibration， micro sample characterization， teaching optical experiments， automatic detection workstations， etc. Especially suitable for optical path systems that are sensitive to lateral displacement and do not allow horizontal offset during adjustment， it is the preferred choice for small-stroke vertical dimension adjustment.

Direct drive and direct progress， precise without shaking. The 7SVM0313 direct-action lifting platform， with the linear guide structure， guards the coaxial accuracy of vertical adjustment， allowing each height fine-tuning in a small space to be stable and controllable.
