After being led out from the winding wheel 21, the suspension rope 8 is wound obliquely downward in the wire groove of the traversing wheel 1 311, and then wound backward in the wire groove of the traversing wheel 2 312. The wire groove at the bottom of the traversing wheel 1 311 coincides with the wire groove of the traversing wheel 2 312, and the suspension rope 8 changes from an oblique downward state to a horizontal state.

[0035] like Figure 2-4 As shown, there are three reversing wheels, including a reversing wheel 1 41, a reversing wheel 2 42, and a reversing wheel 3 43, which are arranged in sequence along the guiding direction of the suspension rope 8.

In this embodiment, the adjustment structures are strip-shaped holes, but are not limited thereto.

[0037] The working principle of the small space high-precision lifting device of the utility model is as follows: hang the jig to be replaced on the hook at the bottom of the lifting rope 8, and start the equipment; press the analog value rising button 71, adjust the pressing force according to the required speed, and release the button after reaching the required height; move the jig to the place where it needs to be placed, press the analog value descending button 72, and the front section will descend quickly. When it needs to contact and cooperate with the product, the pressing force is reduced, and the descending speed is reduced synchronously, which is convenient for manual control; after the jig is fully aligned, it is slowly lowered to prevent dislocation or shaking from hitting the components on the circuit board and causing damage. After the jig is clamped, release the hook and the lifting device is reset.
