the utility model provides a portable safe screwdriver, its structure includes handle, tool bit connecting rod, tool bit, and handle one side is equipped with the storage tank along handle length direction, and the one end of tool bit connecting rod is articulated to be installed in storage tank one end, the other one end of tool bit connecting rod of tool bit detachable installation.

Furthermore, one end of the cutter head connecting rod, which is provided with the cutter head, is provided with a mounting blind hole, the section of the mounting blind hole is in a regular n-polygon shape, and n is 3, 4, 5, 6, 7 or 8; one end of the tool bit is provided with an installation column, the section of the installation column is the same as that of the installation blind hole, and a gap between the installation columns is inserted into the installation blind hole.

Furthermore, the inner side of the storage groove is provided with elastic surfaces which are arranged on two sides of the storage groove, and the distance between the elastic surfaces on the two sides in the storage groove is smaller than the diameter of the cutter head connecting rod.

Further, handle one end still is equipped with a plurality of tool bits and deposits the chamber, and the chamber setting is deposited at the looks remote site of handle installation tool bit connecting rod to the tool bit, and the one end that the handle was equipped with the tool bit and deposits the chamber still is equipped with the shutoff lid, and shutoff lid detachable installs in handle one end.

Furthermore, the plugging cover is screwed at one end of the handle.

Furthermore, a cavity is arranged between the cutter head storage cavity and the plugging cover, the depth of the cutter head storage cavity is smaller than the length of the cutter head, when the cutter head is stored in the cutter head storage cavity, a part of the cutter head is arranged in the cavity, and the cutter head is convenient to take out after the plugging cover is opened.

Compared with the prior art, the screwdriver has the advantages that the screwdriver head connecting rod can be folded and clamped into the storage groove through the arrangement of the storage groove, so that the length of the screwdriver is shortened, the screwdriver head can be arranged on the screwdriver head connecting rod and clamped into the storage groove, the injury to people when the screwdriver is not used is avoided, and the screwdriver can be used after being unfolded; the cutter head of all the other models and types can be placed into the cutter head storage cavity at one end of the handle, and the cutter head can be directly taken out for replacement when replaced, so that the multifunctional electric screwdriver is convenient to use.
