A spring sheet is arranged in an inner hole of the upper cylinder, the spring sheet is sheathed on a rod body of the screwdriver and can slide in the rod body up and down, and the inner hole of the lower cylinder is slightly larger than the width of a screwdriver head. When in use, the anti-slip sleeve is moved upwards to the upper part of the rod body; after the screwdriver head is embedded into a straight flute on a screw head, the anti-slip sleeve is moved to place the screwdriver head and the screw head into a lower round hole, so as to stop the screwdriver head from being transversely slid off in the straight flute, thus avoiding hand injury and damage of machine members caused by the sudden sliding-off of the screwdriver head in operation.
Description
Affiliated technical field
Novel a kind of repair outfit, the specifically a kind of on-slip device of Flathead screwdriver of relating to of this reality.
Background technology
Usually; Flathead screwdriver in use; landing through the straight trough of regular meeting from screw terminal; continue operation again and will find straight trough again accurately; sometimes in operation firmly than conference landing from straight trough suddenly, not doing a good job to injure hand, also may cause the damage of parts; not only time-consuming, and cause damage.
The utility model content
