Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3, an anti-detachment bit, comprising a handle 1, one outer wall of the handle 1 is fixedly connected with a limiting device 2, one side inner wall of the limiting device 2 is clamped with a bit assembly 3, the limiting device 2 includes a connecting head 4, a positioning plug 5, an anti-slip sleeve 6, a limiting sleeve 7, a fixing wrench 8, and a limiting groove 9. One outer wall of the handle 1 is fixedly connected with the connecting head 4, the output end of the connecting head 4 away from the handle 1 is fixedly connected with the positioning plug 5, one outer wall of the connecting head 4 is sleeved with the anti-slip sleeve 6, one outer wall of the connecting head 4 close to the positioning plug 5 is fixedly connected with the limiting sleeve 7, and the limiting sleeve 7 is sleeved on one outer wall of the positioning plug 5. One outer wall of one end of the limiting sleeve 7 is movably connected with the fixing wrench 8, and one side of the top output end of the fixing wrench 8 is provided with the limiting groove 9. The bit assembly 3 includes a bit fixing seat 10, a limiting head 11, and a limiting strip 12. One outer wall of the positioning plug 5 is inserted and matched with the bit fixing seat 10. One inner wall of the bit fixing seat 10 close to the positioning plug 5 is provided with the limiting head 11. One outer wall of the bit fixing seat 10 close to the limiting sleeve 7 is provided with the limiting strip 12.

[0023] Further, the output end of the limiting head 11 is in inserted and matched with the inner wall of the positioning plug 5.

[0024] Further, the top output end of the limiting strip 12 is in sliding fit with the inner wall of the limiting sleeve 7.

[0025] Further, a fixing groove 13 is opened on one outer wall of one end of the bit fixing seat 10 close to the limiting strip 12.

[0026] Further, a fixing head 14 is provided on one side of the top output end of the fixing wrench 8, and the output end of the fixing head 14 is tightly pressed against the fixing groove.

[0027] Working principle: The handle 1 serves as the main body of the entire tool. A limiting device 2 is fixedly connected to one side of the handle 1. The limiting device 2 includes a connecting head 4, a positioning plug 5, an anti-slip sleeve 6, a limiting sleeve 7, a fixing wrench 8, and a limiting groove 9. The connecting head 4 is directly fixed to the handle 1 and provides a plugging basis for the bit assembly 3 through the positioning plug 5. The bit assembly 3 consists of a bit fixing seat 10, a limiting head 11, and a limiting strip 12. Among them, the bit fixing seat 10 is used to fix and install the actual working bit part, and the limiting head 11 and the limiting strip 12 cooperate with the corresponding parts of the limiting device 2 to achieve stable fixation. When the bit assembly 3 needs to be installed, the bit fixing seat 10 realizes plugging cooperation with the positioning plug 5 through the built-in limiting head 11 therein. This step ensures the preliminary positioning of the bit assembly in the vertical direction. At the same time, the limiting strip 12 on the bit fixing seat 10 slides along the inner wall of the limiting sleeve 7 until it reaches the appropriate position. This process not only further enhances the stability of the bit assembly but also prepares for its subsequent locking. After the bit assembly 3 is inserted and preliminarily positioned, by operating the fixing wrench 8, the limiting groove 9 at its top is made to cooperate with the limiting strip 12, and the fixing wrench 8 is pressed downward. As the fixing wrench 8 is pressed, the fixing head 14 at its top is tightly pressed into the fixing groove 13 on the bit fixing seat 10, thereby realizing the locking of the bit assembly 3 in the horizontal direction and effectively preventing the bit from falling off during use. The setting of the anti-slip sleeve 6 increases the comfort and stability of holding during operation and prevents accidental dropping caused by hand slippage. The design of the entire limiting device and the bit assembly, through multi-level plugging, sliding, and locking mechanisms, jointly ensure the stability and safety of the bit during use.
