First, the elimination of common faults 1. The self-sliding of the lens barrel: This is one of the frequent malfunctions of the organism. The microscope solution for the bushing structure can be carried out in two steps. Step 1: Hold the two coarse handwheels with both hands and tighten them relatively hard. If you can't solve the problem, if you can't solve the problem, you should use a special double-column wrench to unscrew a coarse hand wheel and add a friction plate. After the hand wheel is tightened, if the rotation is very laborious, the friction plate is added. Too thick, can be changed to a thin one. It is easy to rotate with the handwheel, and the lens barrel moves up and down easily, and it does not fall on its own. The friction linings can be punched with a waste photographic film and a soft plastic sheet less than 1 mm thick with a punch. Step 2: Check the gears on the coarse handwheel shaft and the rack on the lens barrel. The up and down movement of the lens barrel is accomplished by the gear carrying the rack. The optimal meshing state of the gear and the rack is theoretically that the index line of the rack is tangent to the indexing circle of the gear. In this state, the gear rotates easily and the rack wear is the most Double Desk And Chair,Double School Desk,Double Table Chair,Double School Table AU-PINY FURNITURE CO., LTD , https://www.aupinyjm.com
