• the second control portion aligns with the first control portion after the locking block is assembled with the pawl member;
• the locking block has a second end provided with a second connecting portion connected with the first connecting portion, so that the pawl member and the locking block are rotated synchronously;
• the second connecting portion has a shape corresponding to that of the first connecting portion;
• the first elastic element is received in the third receiving groove and has two ends elastically pressing the two locking modules, so that the engaging portion constantly meshes with the ratchet portion by an elastic force of the first elastic element;
• the first elastic element is biased between the abutting blocks of the two locking modules;
• the control member is pivotally mounted on the main body and is rotatable relative to the main body;
• the control member is rotated to control operation of the screwdriver rotating structure so that the screwdriver rotating structure is operated in a one-way direction or in a two-way direction;
• the control member rests on a side of the driving member or a gap is defined between the control member and the driving member;
• the control member is provided with three positioning grooves arranged annularly and spaced from each other;
• one of the three positioning grooves aligns with the first spring cavity;
• the control member is provided with two receiving spaces, with the three positioning grooves being located between the two receiving spaces;
• the second control portion of each of the two locking modules is received in one of the two receiving spaces;
• the two receiving spaces are arranged symmetrically;
• each of the two receiving spaces has a side provided with a third control portion located adjacent to the three positioning grooves;
• the control member is rotated to a position where the third control portion of one of the two receiving spaces presses the second control portion of one of the two locking modules, so that the engaging portion of one of the two locking modules disengages the ratchet portion;
• the control member has a peripheral face provided with a rotation portion having multiple projections to facilitate rotation of the control member;
• the fixed plate is assembled with the main body and is provided with a pivot hole allowing passage of the restriction portion;
• the pivot hole is provided with multiple limit grooves allowing passage of the limit blocks;
• the pivot hole is pivotally mounted on the second pivot portion and has a first side abutting the second abutting face;
• when the fixed plate is rotated slightly after the limit grooves pass the limit blocks, the limit grooves misalign with the limit blocks, and the first abutting faces of the limit blocks rest on a second side of the fixed plate, so that the fixed plate is secured on the main body without detachment;
• the control member is pivotally mounted on the main body and limited by the fixed plate, so that the control member is sandwiched between the fixed plate and the driving member without detachment;
• the two snap-fit members are assembled with the main body and the driving member;
• each of the two snap-fit members is received in one of the two fourth receiving grooves;
• each of the two snap-fit members is provided with a second spring cavity aligning with the first spring cavity;
• each of the two snap-fit members is provided with a snap-fit block pivotally mounted in the annular groove, so that the driving member is pivotally mounted on the main body by the two snap-fit members;
• each of the two snap-fit members has a bottom provided with a third abutting face directed toward the recess;
• each of the two snap-fit members has two sides abutting the two first side faces and has a first end abutting the second side face, so that each of the two snap-fit members is limited and non-movable in one of the two fourth receiving grooves;
• each of the two snap-fit members has a second end limited by the fixed plate;
• the two snap-fit members are limited by the control member so that the two snap-fit members are mounted on the main body without detachment;
• the third abutting face extends into the recess before assembly of the control member and the fixed plate, so that the recess allows movement of the snap-fit block;
• when the driving member is mounted on the main body, the annular groove slides on the two snap-fit members, and the snap-fit block is snapped into the annular groove;
• the limit grooves align with the limit blocks;
• the control member and the fixed plate are mounted on the main body serially;
• the fixed plate is rotated slightly until the limit grooves misalign with the limit blocks, so that the fixed plate is secured on the main body;
• the control member and the two snap-fit members are assembled on the main body by limit of the fixed plate;
• each of the two snap-fit members is limited by the two first side faces, the second side face, the control member, and the fixed plate, so that the third abutting face is detached from the recess, to interrupt movement of the snap-fit block, and the driving member is pivotally mounted on the main body;
• the positioning element is received in the first spring cavity and the second spring cavity;
• the second elastic element is received in the first spring cavity;
• the second elastic element is biased between a bottom of the first spring cavity and the positioning element, so that the positioning element protrudes from the second spring cavity slightly;
• and
• the positioning element is positioned in one of the three positioning grooves, so that the control member is positioned on the main body and drives the driving member to idle in the counterclockwise direction, to rotate in the counterclockwise and clockwise directions, and to idle in the clockwise direction.
