detailed description

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, so that the protection scope of the utility model can be defined more clearly .

Please refer to Fig. 1 to Fig. 3, the utility model embodiment comprises:

An automatic rotary screwdriver, comprising: a screwdriver head 1, a handle 2, a rotating body 3, a rotating body 4, a button 5 and a return spring 6; the handle 2 is cylindrical, and the center of the upper surface of the handle 2 is provided with a circular groove. The screwdriver head 1 is vertically fixed on the lower surface of the handle 2, the rotating body 3 is vertically fixed at the bottom of the circular groove, and the axis of the screwdriver head 1 and the axis of the rotating body 3 coincide with the axis of the handle 2; The screwdriver head 1, the handle 2 and the rotating body 3 are of an integrated structure. The outer wall of the rotating body 3 is distributed with four convex lines in the axial direction of the rotating body 3 around the axis of the rotating body 3. The rotating body 4 is rotatably sleeved on the rotating body 3, and the inner wall of the rotating body 4 is obliquely arranged There are four pawls 8, the pawls 8 correspond to the convex strips one by one, the pawls 8 can stand on the convex strips, the pawls 8 have certain toughness, the cooperation between the rotary body 4 and the rotary body 3 is equivalent to a ratchet mechanism, and the rotary The positive rotation of the body 4 can drive the rotation body 3 to rotate forward, and the rotation body 3 does not move when the rotation body 4 rotates in the opposite direction; The position is covered with a one-way bearing 9, which is convenient for dynamic and static combination; the button 5 is cylindrical, and the outer diameter of the button 5 is equal to or smaller than the inner diameter of the circular groove. There is an internal thread matched with the external thread, and the button 5 is connected with the rotary body 4 through the thread; when the button 5 is pressed, the rotary body 4 rotates; the upper end of the rotary body 3 protrudes from the rotary body 4, and the rotary body 3 The diameter of the protruding part is equal to the inner diameter of the circular hole; it can guide the button 5 and facilitate pressing the button 5 .
