Referring to fig. 1, the present invention discloses a screwdriver, which comprises a screwdriver head, a screwdriver head sleeve, an extension bar, a screwdriver head sleeve, a ratchet wheel, an inner hexagonal sleeve, a rocking handle, a gear bin, a screwdriver handle, a cover, a screwdriver head bin and a handle bin.

The bottom of the handle of the screwdriver is provided with a gear bin, and a pair of bevel gears in meshing transmission is arranged in the gear bin; as shown in fig. 1, the axis of the first bevel gear is parallel to the axis direction of the screwdriver handle, and the second bevel gear is vertically distributed at 90 degrees with the first bevel gear; the shaft of the second bevel gear extends out of the right side of the gear bin, the shaft hole is formed in the right end of the shaft of the second bevel gear, an inner hexagonal sleeve is installed in the shaft hole, the cross section of the inner hexagonal sleeve and the cross section of the shaft hole are hexagonal, and the inner hexagonal sleeve and the cross section of the shaft hole are matched with the hexagonal shape of the part A of the rocking handle in a convenient mode.

A handle bin is arranged at the position above the right side of the handle of the screwdriver and used for inserting the part C of the rocking handle.

The rocking handle comprises a handle body, a handle and a rocking bar; the upper end of the handle body is connected with the handle, and the lower end of the handle body is connected with the rocker; the middle position of the rocker along the axial direction is connected with the lower end of the handle body, and the handle body is arranged obliquely to the rocker; the upper end of the handle body is provided with a handle, one end of the handle is fixedly connected to the upper end of the handle body, the handle body is rotated by holding the handle by hand, the rotation of the rocker is realized, the two ends of the rocker are respectively marked as an A part and a B part, when the rocker is mounted in the forward direction, the A part is inserted into the inner hexagonal sleeve, and the rocker can rapidly act by shaking; when the rocker is reversely mounted, namely the part B is inserted into the inner hexagonal sleeve, the part C is inserted into the handle bin, the rotating part of the screwdriver can be fixed, and the screwdriver can perform high-torque operation by adding a locking mechanism of the ratchet wheel part.

The bottom of the gear bin is fixedly provided with a ratchet bin, a ratchet structure is arranged in the ratchet bin, and the adopted bidirectional ratchet structure can only rotate rightwards when a right-handed mode is set, and can only rotate leftwards when a left-handed mode is set. The axis of the ratchet wheel is coaxial with the axis of the first bevel gear, the bevel gears in the gear bins are meshed for transmission to realize rotation of the ratchet wheel below the gear bins, the ratchet wheel has a locking function, rotation of the screwdriver in the left and right directions can be realized by adjusting the ratchet wheel, the ratchet wheel is arranged at the middle position, the middle position is in a locking state, and the screwdriver can not rotate left or right.

When the installation of rocker direction was that the B part of rocker was installed in the hexagonal cover in, the handle inserted the handle storehouse in, and whole rocking handle can't rotate and cause whole bevel gear to be unable pivoted, and the screwdriver can carry out manual other operations this moment, and whole extension bar can not carry out the self-rotation under the drive of ratchet. Other high torque operations may be performed.
