[0057] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0058] according to Figures 1 to 8A multifunctional utility knife comprises: a blade body 1, which is composed of left and right shells fitted together, which can usually be made of plastic injection molding and connected with screws to form an installation space between the left and right shells, a blade functional component 2, which is arranged at the front of the blade body 1; a screwdriver functional component 3, which is arranged at the rear of the blade body 1; the focus of its improvement is that the screwdriver functional component 3 includes a screwdriver barrel 4, which is L-shaped as a whole, and a connecting part 5 is provided at the front end to be rotatably fixed to the blade body 1; a barrel cavity 6 is provided at the rear end to fix a pluggable screwdriver head 36; a screwdriver storage cavity 7 is provided at the back of the blade body 1, and the screwdriver storage cavity 7 matches the size of the screwdriver barrel 4, so that the screwdriver storage cavity 7 can accommodate the screwdriver barrel 4.

[0059] The specific structure is that there is a metal rear connecting seat 8 fixed to the rear part of the blade 1. In order to simplify the structure, the metal rear connecting seat 8 is in the form of a metal plate in this embodiment, and it is a double-piece metal plate form, which is simple and has appropriate strength. The metal rear connecting seat 8 is provided with a connecting shaft hole 9. Correspondingly, a connecting hole 10 is provided on the blade 1, and the connecting part 5 of the screwdriver barrel 4 is also provided with an shaft hole 11. The connecting shaft 12 passes through the connecting shaft hole 9 of the metal rear connecting seat 8, the shaft hole 11 of the front connecting part of the screwdriver barrel and the connecting hole 10 on the blade 1. The limit screw 13 is fixed to the end of the connecting shaft 12, firmly fixing the left and right shells to the metal rear connecting seat 8. At the same time, the double-piece metal plate is formed into an integral metal rear connecting seat 8 through the connecting shaft and the limit screw, and the screwdriver functional component 3 is rotatably and foldably connected to the rear part of the blade 1.

[0060] To facilitate rotational folding and securing, a locking mechanism is provided between the screwdriver functional assembly 3 and the blade 1. Specifically, a screwdriver locking hole 14 is provided on both the metal rear connector 8 and the blade 1. A screwdriver locking pin 15, which can move left and right, is located within the screwdriver locking hole 14. A reduced diameter portion 16 is located in the middle of the screwdriver locking pin 15. A locking spring 17 is secured to the bottom of the screwdriver locking pin 15, ensuring that the screwdriver locking pin 15 maintains an outward movement. A locking notch 19 is provided on the front connection of the screwdriver barrel 4, which cooperates with the reduced diameter portion 16 and the non-reduced diameter portion 18 of the screwdriver locking pin 15 to lock and unlock the screwdriver functional assembly 3 in either the folded or unfolded state. A stopper mechanism is also provided between the screwdriver functional assembly 3 and the blade 1. Specifically, a stopper pin 20 is located on the underside of the metal rear connector 8 and engages with the front connection of the screwdriver barrel 4 to prevent damage to the screwdriver barrel 4 due to excessive force during use.

[0061] The blade functional component 2 can also be connected to the blade body 1 in a rotatable and foldable manner. The blade housing 22 consists of a blade seat 23 and a blade cover 24, which are connected with screws after being aligned to form a blade mounting cavity. The blade seat 23 and the blade cover 24 are preferably made of engineering plastics, which have the advantages of high strength and high wear resistance. The front part of the blade body 1 has a blade edge, and the rear connecting part has an axial hole 9. The blade 25 is arranged in the blade mounting cavity for cutting and other functions. A blade changing button and a spring sheet are also installed. This is common knowledge. The metal front connecting seat 26 is fixed on the blade body 1. In order to simplify the structure and facilitate assembly, the metal front connecting seat 26 in this embodiment is made of sheet metal. The metal front connecting seat 26 has a connecting shaft hole 9. Correspondingly, the blade body 1 has a connecting hole 10. The connecting shaft 12 passes through the connecting shaft hole 9 of the metal front connecting seat 26, the shaft hole 9 at the connecting part of the blade shell 22 and the connecting hole 10 on the blade body 1. The limit screw 13 is fixed to the end of the connecting shaft 12 for limiting, fixing the blade shell 22 and the metal front connecting seat 26 together, so that the blade functional component 2 can be rotatably and foldably connected to the front part of the blade body 1, and the blade functional component storage cavity 30 is set at the lower part of the blade body 1 for the blade functional component 2 to be hidden in the storage state.

[0062] Similarly, to facilitate rotational folding and fixing, a locking mechanism is provided between the blade functional assembly 2 and the blade body 1. A blade functional assembly locking hole 21 is arranged on the metal front connecting seat 26 and the blade body 1. A blade functional assembly locking pin 27 has a centrally located reduced diameter portion 16 and is positioned within the blade functional assembly locking hole 21, allowing it to move left and right. A locking pin spring 17 is provided at the bottom of the blade functional assembly locking pin 27, ensuring that the blade functional assembly locking pin 27 always maintains an outward movement tendency. A locking opening 19 is provided at the connection portion of the blade housing 22. The locking opening 19 cooperates with the reduced diameter portion 16 and the non-reduced diameter portion 18 of the blade functional assembly locking pin 27 to achieve locking and unlocking of the blade functional assembly 2 during rotational folding and unfolding. A limit brake mechanism is also provided between the blade functional assembly 2 and the blade body 1. Specifically, a brake pin 20 is provided on the upper side of the metal front connecting seat 26, which cooperates with the rear connection portion of the blade housing 22 for limit braking, preventing the blade housing 22 from being excessively stressed and thus damaged during use.

[0063] The front part of the metal front connecting seat 26 is also provided with a prying plate 28. The prying plate 28 is preferably made of metal material. A bayonet 29 is opened at the front part of the prying plate 28. The bayonet 29 matches the tail of the nail, which is convenient for the user to use the prying plate 28 to take out the nail. In addition, the prying plate 28 also serves as another metal plate of the metal front connecting seat 26, forming a double-piece metal plate form, that is, the prying plate 28 also serves as a part of the metal front connecting seat 26, and the sheet metal plate of the metal front connecting seat 26 is used to divide the internal installation space of the blade body 1 into left and right cavities. The left cavity cooperates with the blade functional component 2 to become a blade functional component storage cavity 30, and the other cavity becomes a blade storage cavity 31, which can be used to store blades for easy replacement. It has a blade holder 32, and the blade holder 32 has a plug-in slot 33 for supplying blades. The piece 25 is inserted and fixed; the rear part has a connecting hole 10. Because the metal rear connecting seat 8 adopts the form of a double-piece metal plate, there is another one-piece metal plate 34 with a semi-connecting hole on its side. Correspondingly, the metal front connecting seat 26 also has a semi-connecting hole. The blade holder 32 is rotatably connected between the metal rear connecting seat 8 and the metal front connecting seat 26 by a connecting piece, and forms a relatively strong connecting skeleton. Multiple blades 25 are pluggable and fixed in the plug-in slot 33, which are plugged and fixed on the blade holder 32. The blades 25 are traditional trapezoidal cutting blades and W-shaped hook blades, which are convenient for users to use under different needs. An elastic clip 35 is fixed on the outer wall of the blade body 1, which is convenient for users to clamp the tool on the tool belt or tool rack through the elastic clip 35.

[0064] When the user needs to use the blade function component 2 and the screwdriver function component 3 of this product, he only needs to press the screwdriver locking pin 15 or the blade function component locking pin 27 by hand to make the reduced diameter part 16 and the locking opening 19 cooperate with each other to complete the unlocking, and let the blade function component 2 or the screwdriver function component 3 rotate along the connecting shaft 12 to complete the expanded state, and then release the screwdriver locking pin 15 and the blade function component locking pin 27 to make the non-reduced diameter part 18 and the locking opening 19 engage with each other to complete the locked state.
