A first bit 10 is fixedly connected to the inner wall of the fixed head 22. A second bit 11 is fixedly connected to the outer wall on the right side of the first connecting shell 8;

[0025] Specifically, the electric push rod 3 drives the connecting plate 4 to drive the pressure rod 5 to rotate. When the pressure rod 5 rotates, the rotating rod 1 can ensure the stability of the pressure rod 5, and under the limitation of the first limiting rod 7 and the rotating rod 1, the pressure rod 5 drives the clamping plate 6 to slide into the inner wall of the clamping groove 9 and the first connecting shell 8, achieving the effect of quickly installing and disassembling the first connecting shell 8 and quickly installing and disassembling the first bit 10.

[0026] Refer to Figure 3 , a hand guard 12 is slidably connected to the outer wall of the rotating rod 1, and an anti-slip rod 15 is fixedly connected to the inner wall of the hand guard 12; the outer wall of the anti-slip rod 15 is slidably connected to the inner wall of the rotating rod 1, and a rotating block 13 is fixedly connected to the outer wall of the hand guard 12; a second limiting rod 14 is fixedly connected to the outer wall of the rotating block 13, and the outer wall of the second limiting rod 14 is slidably connected to the left inner wall of the rotating block 13;

[0027] Specifically, the hand guard 12 drives the anti-slip rod 15 to insert into the inner wall of the rotating rod 1. During use, the anti-slip rod 15 can prevent the hand guard 12 from falling off and slipping, and the material of the hand guard 12 can be maintained for stability during operation according to different working conditions.

[0028] Refer to Figures 3 - 4 , a socket 16 is slidably connected to the inner wall of the hand guard 12, a screw rod 18 is fixedly connected to the outer wall of the socket 16, and the outer wall of the screw rod 18 is threadedly connected to the inner wall of the hand guard 12; a clamping head 17 is fixedly connected to the left outer wall of the socket 16, a connecting sleeve 19 is slidably connected to the outer wall of the clamping head 17, and an anti-detachment ring 20 is arranged on the outer wall of the connecting sleeve 19; the outer wall of the anti-detachment ring 20 is fixedly connected to the second connecting shell 21, and the outer wall of the second connecting shell 21 is fixedly connected to the inner wall of the hand guard 12;

[0029] Specifically, after the socket 16 rotates into the inner wall of the hand guard 12 through the screw rod 18, it achieves the effect of quickly installing the socket 16. During use, when the clamping head 17 slides into the inner wall of the connecting sleeve 19, it achieves the effect of quickly connecting the hand guard 12, and the second connecting shell 21 and the anti-detachment ring 20 prevent the connecting sleeve 19 from falling off, increasing the stability during use.

[0030] Working principle: When the double-bit tool needs to be used, the electric push rod 3 drives the connecting plate 4 under the limit of the connector 2, driving the pressure rod 5 to rotate. During the use process, when the pressure rod 5 rotates, the stability of the pressure rod 5 can be ensured through the rotating rod 1, and under the limit of the first limiting rod 7 and the rotating rod 1, the pressure rod 5 drives the clamping plate 6 to slide into the inner wall of the clamping groove 9 and the first connecting shell 8, achieving the effect of quickly installing and disassembling the first connecting shell 8 during use, and achieving the effect of quickly installing and disassembling the first bit 10, so that different bits can be quickly replaced according to the usage situation during use. During use, the clamping groove 9 not only prevents falling off, but also when the clamping plate 6 slides into the inner wall of the clamping groove 9 during use, it can prevent the first bit 10 and the fixed head 22 from shaking during use, thereby improving the hand feeling during use and increasing the accuracy when the bit rotates the screw during use. During use, the hand guard 12 drives the anti-slip rod 15 to insert into the inner wall of the rotating rod 1, achieving the effect of quickly connecting and using the hand guard 12 and the rotating rod 1 during use. During use, the anti-slip rod 15 prevents the hand guard 12 from sliding on the outer wall of the rotating rod 1 during rotation, resulting in the hand guard 12 slipping. During use, the screw 18 can quickly install the socket 16 and the chuck 17. During use, when the hand guard 12 is damaged, it can quickly open the two hand guards 12 for replacement, and during use, the material of the hand guard 12 can be replaced according to different environmental uses to ensure that the hand guard 12 does not slip and is not dropped in different working environments. The rotating block 13 drives the rotating rod 1 to merge under the limit of the second limiting rod 14, the socket 16 drives the chuck 17 to insert into the inner wall of the connecting sleeve 19, and the anti-drop ring 20 and the second connecting shell 21 prevent the connecting sleeve 19 from detaching, achieving the effect of quickly installing the hand guard 12 during use. And during use, the hand guard 12 can prevent hand injuries when rotating the screw, improving the comfort and safety during use, and using the wrench and the rotating block 13 can achieve a better force application effect.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
