Use and structure of charging drill

Working principle of electric wrench

When the end face of the nut contacts the end face of the workpiece, the resistance moment rises sharply. The rotating spiral groove causes the ball to move backward with the active impact block against friction and the pressure of the working spring, causing the teeth that engage the active impact block and the driven impact block to disengage from each other. At this point, the driven impact block does not move, while the active impact block continues to move rearward.

Precautions for level gauge

The level gauge is a measuring tool with strict packaging requirements. Each level gauge shall be packed in a shockproof box made of foam material, coated with anti rust oil and placed in a plastic bag before packaging. The shockproof box is then packed in a strong cardboard or wooden box with the specified markings painted on the outside. The level meter should be stored in a dry, ventilated, non corrosive gas warehouse. Strictly prevent falling, collision and rain during transportation.

How to use the level

The scale value of the level gauge is expressed in terms of angle (seconds) or slope, which means the angle at which the bubble is offset by one grid of work tilt, or the height at which the bubble is offset by one grid of work surface tilt over a length of one meter.
