[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0030] Example 1

[0031] Reference Figures 1-2 This is the first embodiment of the present utility model. This embodiment provides an internal hex screwdriver with a structure that provides ratchet seats at both ends, making it easier to install and remove internal hex screws during use. This makes the screwdriver more labor-saving and convenient to use. It includes a linkage unit 100, which includes a rotating base 101, a telescopic rotating shaft 102, and a rotating gear 103. The rotating base 101 is provided with the telescopic rotating shaft 102, and the telescopic rotating shaft 102 is provided with the rotating gear 103.

[0032] A screwdriver shank 200 is provided with a linkage unit 100. The screwdriver shank 200 includes an internal hex head 201, a lower ratchet seat 202, a mounting base 203, an upper ratchet seat 204, and a gripping handle 205. The screwdriver shank 200 is provided with the lower ratchet seat 202 and the upper ratchet seat 204. The upper ratchet seat 204 is connected to the internal hex head 201 through the mounting base 203. The screwdriver shank 200 is provided with a gripping handle 205.

[0033] In use, the hex head 201 is installed onto the lower ratchet seat 202 or the upper ratchet seat 204 via the mounting base 203. After installation, the screw is fixed by gripping the gripping handle 205 and cooperating with the internal ratchet rotation structure.

[0034] Example 2

[0035] Reference Figure 2 and Figure 3This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a connecting structure, which solves the problem that existing hex wrenches cannot achieve the function of ratchet wrenches. It includes an upper ratchet seat 204, which includes a rotating ratchet 204a, a connecting spring 204b, an adjusting ratchet 204c, and a conversion cam 204d. The rotating ratchet 204a is provided inside the upper ratchet seat 204. An adjusting ratchet 204c is provided at one end of the rotating ratchet 204a. The connecting spring 204b is provided on the adjusting ratchet 204c. The conversion cam 204d is provided on the adjusting ratchet 204c.

[0036] Preferably, the structure of the upper ratchet seat 204 is the same as that of the lower ratchet seat 202. The lower ratchet seat 202 and the upper ratchet seat 204 are arranged perpendicularly to each other about the gripping handle 205. The gripping handle 205 includes a linkage plate 205a, a reset groove 205b, a reset spring 205c and a locking groove 205d. The linkage plate 205a is provided inside the gripping handle 205. The linkage plate 205a has a reset groove 205b and a locking groove 205d. The reset spring 205c is provided at one end of the linkage plate 205a.

[0037] Furthermore, an adjustment base 206 is provided on the gripping handle 205, and a reversing block 207 is provided on the adjustment base 206. A limit button 208 and a reset button 209 are provided at one end of the reversing block 207.

[0038] In use, by pressing down the limit button 208 on the lower ratchet seat 202 or the upper ratchet seat 204, the internal linkage plate 205a, in conjunction with the locking protrusion 208b, limits the movement and completes the fixation. By adjusting the ratchet seat at the end where the limit button 208 is not pressed using the reversing lever 207, the internal actuating gear 207b drives the conversion cam 204d to rotate according to the user's work needs, thereby driving the adjusting ratchet 204c at the limit end to achieve the effect of a ratchet wrench.

[0039] Example 3

[0040] Reference Figure 3 and Figure 5 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a solution to the problem of not being able to adjust two ratchets in different directions. It includes a positioning seat 104 provided at one end of the rotating gear 103, a rotating base 101, a telescopic shaft 102 and two rotating gears 103 arranged perpendicularly to the positioning seat 104, a limiting boss 105 provided on the rotating base 101, an inner connecting groove 107 and a limiting groove 108 provided in the telescopic shaft 102, and the rotating base 101 and the telescopic shaft 102 are connected to each other by a telescopic spring 106.

[0041] Preferably, the reversing block 207 is provided with a block shaft 207a, one end of the block shaft 207a is provided with a toggle gear 207b, the limit button 208 is provided with a guide seat 208a, the guide seat 208a is provided with a guide rod 208a-1, the guide seat 208a and the gripping handle 205 are provided with a guide spring 208a-2, and the limit button 208 is also provided with a locking protrusion 208b;

[0042] Furthermore, the reset button 209 is located on one side of the limit button 208. The reset button 209 is provided with a button linkage 209a, a button spring 209c is provided at one end of the reset button 209, and a reset protrusion 209b is also provided on the reset button 209.

[0043] When in use, pressing down on the limit button 208 will simultaneously cause the locking protrusion 208b to move within the locking groove 205d. Due to the structure of the locking groove 205d, the locking protrusion 208b will be fixed after pressing down, thus fixing the limit button 208. The limit button 208 will then limit the linkage unit 100, fixing the telescopic shaft 102 towards the end closer to the rotating base 101. This will disengage the rotating gear 103 connected to one end of the telescopic shaft 102 from the actuating gear 207b, facilitating the adjustment of the ratchet direction at the other end. When adjustment is needed, pressing the reset button 209 will release the limitation under the action of the reset protrusion 209b and the reset groove 205b, allowing for reversal adjustment.
