Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] A kind of manual two-way self-shifting speed-up screwdriver of the present invention, as figure 1 , figure 2 and image 3 As shown, it includes a handle 2, one end of the handle 2 is matched with a rotating cap 1, the other end of the handle 2 is radially contracted, and one end of the magnetic suction groove 3 of the cutter head is connected to the outer ring of the bearing 5, and the magnetic suction groove 3 of the cutter head The other end is adsorbed with a cutter head 4;
[0022] The rotating cap 1 communicates with the handle 2, and is equipped with an acceleration gear mechanism. The acceleration gear mechanism is fixedly connected to one side of the plum-shaped cam upper cover 9 with a protruding rod, and the other side of the plum-shaped cam upper cover 9 is connected to the guide rail bar 6. One end is connected, and the...

The invention discloses a manual two-way self-shifting acceleration screwdriver which comprises a handle. One end of the handle is matched and connected with a turncap, and the other end of the handleis radially shrunk and is connected with one end of a screwdriver head magnetic-adsorption slot. The other end of the screwdriver head magnetic-adsorption slot adsorbs a screwdriver head. The turncapcommunicates with the inner part of the handle and is provided with an acceleration gear mechanism, and the acceleration gear mechanism is fixedly connected with one side face with a salient rod of aplum-shaped top cam cover. The other side face of the plum-shaped top cam cover is connected with one end of a guide rail rod, and the other end of the guide rail rod passes through the inner ring ofthe bearing and is fixedly connected with the screwdriver head magnetic-adsorption slot to form a whole. The guide rail rod is rotationally matched and connected with the other end of the handle through the outer ring of the bearing. According to the screwdriver, when a user holds the turncap on the tail by hand and rotates the handle in any direction, the acceleration mechanism starts to realizethe accelerating rotation of the screwdriver head. When the palm comes off the turncap, the operation process of tightening by a screw is completed. The screwdriver is easy and natural in use and greatly improves the operation efficiency. Two states are switched at will, so the screwdriver is convenient to use.
Description
technical field [0001] The invention belongs to the technical field of screwdrivers and relates to a manual two-way self-shifting speed-up screwdriver. Background technique [0002] At present, the ordinary screwdriver used by people is the operation mode that the handle rotates once and the cutter head rotates once, which cannot solve the problem of repeated operations in the screw loosening stage, and the screwing force required for the loosening stage of the screw tightening operation is small , The number of times of repeated twisting is large, and it takes a long time, which undoubtedly consumes a lot of time and energy for the user. Contents of the invention [0003] The purpose of the present invention is to provide a manual two-way self-shifting speed-up screwdriver, which solves the problems of many times of repeated turns and long time-consuming during the use of the existing screwdriver. [0004] The technical scheme adopted in the present invention is a manual...
