DETAILED DESCRIPTION

[0020] In order to make the technical solution more clear to those skilled in the art, Figure 1 -6 Detailed description of the technical solution of the utility model:

[0021] A convenient structure for popping out a shell for storing bits of a precision screwdriver, comprising a rotating bit frame 1, a screwdriver body placement slot 2 arranged on the rotating bit frame 1, a plurality of bit mounting slots 3 arranged on the rotating bit frame 1, a tool magazine base 4 arranged below the rotating bit frame 1, a limiting mechanism 5 symmetrically arranged on both sides of the tool magazine base 4, and a mounting shell 6 arranged on the outer side of the rotating bit frame 1. The mounting shell 6 is sleeved on the rotating bit frame 1 and is mounted on the tool magazine base 4 by snapping the limiting mechanism 5. Bits of various types are placed in the bit mounting slots 3, and the screwdriver body is mounted The screwdriver body is placed in the groove, which is convenient for selection according to usage needs. When working, the mounting shell 6 is engaged with the tool magazine base 4 through the limiting mechanism 5, which can store the rotating tool head rack 1 and the screwdriver body. When the screwdriver needs to be used, the mounting shell 6 is pressed to separate it from the tool magazine base 4, the mounting shell 6 is removed, and then the screwdriver body and the appropriate tool head model are removed, installed, and then the screwdriver is used. After use, the screwdriver body and the tool head are returned to their original positions, and then the mounting shell 6 is sleeved on the rotating tool head rack 1, and engaged with the tool magazine base 4 through the limiting mechanism 5.

[0022] Among them, a multi-layer cutter head mounting frame 7 is provided on the rotating cutter head frame 1, and a plurality of cutter head mounting grooves 3 are provided in a circumferential array on the cutter head mounting frame 7.
