The opposite two sides of its inner wall are equipped with and the matched groove of the spring latch lock；The reinforced bar sleeve plug division includes that an internal diameter is greater than
The tubular shell of reinforced bar sleeve outer diameter, the tubular shell is closed at one end open at one end, and closed end and the motor are defeated
One end of shaft plug division is welded, and tubular outer casing inner wall inlays the anti-friction rubber layer of a high resiliency, and the high resiliency is anti-friction
The internal diameter of rubber layer is less than the outer diameter of reinforced bar sleeve；The protrusion of the machine shaft of the electric screw driver is inserted into the silk head
Machine shaft spliced eye in, and the spring latch lock of the machine shaft two sides is stuck in the recessed of the machine shaft spliced eye inner wall
In slot.
The utility model is mainly used for mainly using common hand electric to silk on straight thread reinforced bar sleeve one end
Screwdriver provides power, and electric screw driver uses the motor of 80~150 Ns of rice of torque, anti-friction by the high resiliency in silk head
Rubber layer and the frictional force of straight screw sleeve outer wall rotate straight screw sleeve, realize quickly upper silk, behaviour using the high revolving speed of motor
Make easy, quick construction, being usually manually screwed into a sleeve needs time-consuming 12s, and only needs 2s, every reinforcing bar using the utility model
Upper silk shortens for 5/6ths time, and big heavy construction is measured to reinforcing bar connection, can greatly save the construction time, improves construction
Efficiency, economic benefit are huge.
