The screw driving assembly 30 includes a first screw 31 and a second screw 32 connected with each other, the first screw 31 is rotatably connected to the movable chuck 22, the second screw 32 is rotatably connected to the fixed assembly 10, and rotating the second screw 32 in a first direction rotates the first screw 31, so that the first screw 31 drives the movable chuck 22 to move toward the fixed chuck 21. The pitch of the first screw 31 is different from the pitch of the second screw 32 to limit the movable chuck 22 to move only on the first screw 31, so as to avoid the movable chuck 22 moving too long when holding screws of other sizes, thereby improving the working efficiency of the multifunctional tool 100. In this embodiment, the pitch of the first screw 31 is smaller than the pitch of the second screw 32, so that when the second screw 32 is rotated in a large range, a small distance movement of the movable chuck 22 on the first screw 31 is realized, thereby facilitating the application of force to the screw driving assembly 30. In other embodiments, the pitch of the first screw 31 is greater than the pitch of the second screw 32, such that a small range of rotation of the second screw 32 allows for a large distance movement of the movable clamp 22 on the first screw 31, thereby allowing for a quick adjustment of the distance between the fixed clamp 21 and the movable clamp 22. In application, the first screw 31 and the second screw 32 may be of an integral structure, or may be fixedly connected by welding.

The second end 212 of the fixed jaw 21 is provided with a first jaw 214 on the side facing the movable jaw 22, and the fourth end 222 of the movable jaw 22 is provided with a second jaw 225 on the side facing the fixed jaw 21. The first jaw 214 and the second jaw 225 form a jaw portion 226, and the movable clamp 22 moves towards or away from the fixed clamp 21, so that the jaw portion 226 can be adapted to screws with different sizes, thereby avoiding the use of wrenches with different sizes when disassembling a workpiece, and improving the adaptability and the working efficiency of the multifunctional tool 100. In the present embodiment, the structure of the jaw portion 226 is the same as that of the wrench end portion 224, and the size of the jaw portion 226 is smaller than that of the wrench end portion 224, so that the multifunctional tool 100 can be adapted to more types of screws, and the adaptability and the working efficiency of the multifunctional tool 100 can be improved.

Specifically, the multi-function tool 100 may be used in place of a nail puller, the jaw portion 226 removing a nail by picking up a different size nail when the movable jaw 22 moves toward the fixed jaw 21.
