Described protection bucket is arranged on two flexible thes tip of the axis, and makes stretching motion under the effect of two telescopic shafts, when the state of stretching out completely, the bottom surface of protection bucket lower than or equal the point of a knife plane of screwdriver.
After using electric screw driver, on-off controller on pressing electric screw driver, two telescopic shafts stretch out from bottom under the effect of motor, because protection bucket is arranged on two flexible thes tip of the axis, thus protection bucket is synchronously stretched out together along with two telescopic shafts, stretching out under state completely, the bottom surface of protection bucket is not higher than the point of a knife plane of screwdriver, in being enclosed in by the point of a knife of screwdriver, the point of a knife of screwdriver and other materials is avoided to touch; Before using electric screw driver, again press on-off controller, motor drives two telescopic shafts to make retraction movement, drives protection bucket upwards to retract, then starts electric screw driver and rotate.
Described protection bucket top is provided with two connecting plates; described connecting plate is provided with circular hole, the nut that described flexible the tip of the axis is provided with screw thread and mates with screw thread, and flexible the tip of the axis is through circular hole; together with bucket is movably arranged on protection by telescopic shaft by nut, be convenient for changing impaired protection bucket.
The bottom surrounding of described body is provided with LED, opens LED, can conveniently operation under the situation of dark.
The bottom of described protection bucket is provided with bottom, covers bottom, prevents the point of a knife of screwdriver from touching other materials from bottom.
The bottom of described bottom and protection bucket is respectively equipped with screw thread two, and described bottom and protection bucket are linked together by screw thread two, make connection more fastening.
Described protection bucket and bottom material are transparent safety glass, visual, are convenient to watch inner screwdriver.
Described protection bucket is provided with hole, saves material, cost-saving.
Beneficial effect:
The present invention is a kind of electric screw driver with protective action, comprises body and the screwdriver being positioned at organism bottom, also comprises motor, on-off controller, two telescopic shafts and protection bucket; Two telescopic shafts are connected on motor, and under the effect of motor, do synchronization telescope motion; Protection bucket is arranged on two flexible thes tip of the axis, and makes stretching motion under the effect of two telescopic shafts, and when the state of stretching out completely, the bottom surface of protection bucket is not higher than the point of a knife plane of screwdriver.
1, by arranging motor, on-off controller, two telescopic shafts and protection bucket; after electric screw driver uses; pressing on-off controller; two telescopic shafts are stretched out completely; the bottom surface of protection bucket is not higher than the point of a knife plane of screwdriver; in the point of a knife of screwdriver is enclosed in, avoids the point of a knife of screwdriver and other materials touch and scratch material surface, cause bad order.
2, together with bucket is movably arranged on protection by telescopic shaft by nut, impaired protection bucket is convenient for changing.
3, the bottom surrounding of body is provided with LED, opens LED, can conveniently operation under the situation of dark.
4, protect the bottom of bucket to be provided with bottom, cover bottom, prevent the point of a knife of screwdriver from touching other materials from bottom.
5, the bottom of bottom and protection bucket is respectively equipped with screw thread two, and bottom and protection bucket are linked together by screw thread two, and screw thread two makes the connection between bottom and protection bucket more fastening.
6, protect bucket and bottom material to be transparent safety glass, realize visual, be convenient to watch inner screwdriver.
7, protect bucket to be provided with hole, save material, cost-saving.
