Detailed Description

The invention will be further described with reference to the following figures 1-2 and specific examples:

embodiment 1, the utility model discloses a from just from anti-skidding screwdriver pullover of tighting, including hexagonal prism chuck 2, lead screw 3, knob and spring stop 4, staple bolt pressure spring 5, staple bolt 6, jack catch 7, jack catch spring arm 9 and screwdriver pullover 10, the central line of hexagonal prism chuck 2, lead screw 3 and screwdriver pullover 10 aligns and welds integratively; the knob ends 4 internal diameters with the spring and is equipped with and pass through the thread bush in the lead screw 3 outside with 3 complex screws of lead screw, the knob ends with the spring and ends closely sliding connection screw rod cover with the jump ring card on the ware 4, a plurality of jack catch spring arms 9 of shaft coupling on the screw rod cover, the lower extreme of jack catch spring arm 9 is equipped with jack catch 7 inwards, 5 downside are ended with the spring to the knob to staple bolt pressure spring 5 one end connection, the other end is equipped with staple bolt 6, staple bolt pressure spring 5 and staple bolt 6 cover are in the screw rod cover and the jack catch spring arm 9 outside, screwdriver pullover 10 and staple bolt 6 are located the jack catch top.

A self-aligning self-tightening anti-slip screwdriver sleeve is characterized in that a knob and a spring stopper 4 are barrel-shaped.

A self-aligning self-tightening anti-slip screwdriver sleeve is characterized in that a screw sleeve is axially connected with 6 elastic claw spring arms 9.

A self-correcting self-tightening anti-slip screwdriver sleeve head is characterized in that clamping jaws 7 on 6 elastic clamping jaw spring arms 9 face to the central lines of a hexagonal prism chuck 2, a screw rod 3 and a screwdriver sleeve head 10.

A self-correcting self-tightening anti-skid screwdriver sleeve head is characterized in that a hexagonal prism chuck 2 is a connector for connecting a universal clamp.

The self-correcting self-tightening antiskid screwdriver sleeve head has a screwdriver connecting port in the lower end.

A self-aligning self-tightening anti-slip screwdriver sleeve is characterized in that after a screwdriver 1 is sleeved on the self-aligning self-tightening anti-slip screwdriver sleeve, the screwdriver is clamped by a universal clamp, the function of the screwdriver is the same as that of a universal screwdriver connecting rod, and tapping and taking work under most conditions can be completed.

The lower extreme of jack catch spring arm is equipped with the jack catch inwards, and jack catch spring arm annular evenly distributed is fit for snatching countersunk head and flat head screw. The claw is connected with the claw spring arm and the screw rod sleeve at the upper end of the claw spring arm into a whole. The claw spring arm is an elastic arm, and when the anchor ear moves upwards, the whole body is outwards expanded to be enough to be sleeved in the head of the screw 8.
