Description

Technical Field

[0001] The utility model relates to the technical field of utility knives, in particular to a multifunctional utility knife. Background Art

[0002] A utility knife, also known as a cutting knife or wallpaper knife, is mainly used for cutting and trimming relatively soft materials. Generally, it consists of a handle and a blade, and mainly has a pull-out structure or a rotary structure. The blade is generally in a bevel shape, and usually has a breaking line on the blade. When the blade becomes blunt, it can be broken along the scoring line on the blade body to expose a new cutting edge, or the blade can be replaced for convenient use. Some utility knives on the market have the function of a screwdriver while having the cutting function. However, since different patterns of screwdriver bits are required for different screws, the utility knives with screwdriver function on the market usually only have one type of screwdriver bit or need to set up a storage bin for the screwdriver bit, which affects the user experience and is too heavy.

[0003] It is found that a utility knife with the patent number CN200920117973.8 includes a housing and a blade. A screwdriver socket is provided at the head of the housing. When in use, the screwdriver shaft can be inserted into the screwdriver socket at the head of the housing, so that the utility model can also be used as a screwdriver, thus realizing the multifunction of the utility knife. However, the housing for the screwdriver bits of this product needs to store multiple patterns of screwdriver bits, which affects the user's hand feeling and weight when using.

[0025] The following further describes the present utility model in detail in conjunction with the embodiments of the drawings.

[0026] According to Figures 1 to 6, a multi-functional utility knife, which includes a knife body 1, a blade 2, a blade transmission part 3, and a screwdriver fixing part 4. A knife body cavity 5 is opened at the front end of the knife body 1. The blade 2 is telescopically fixed in the knife body cavity 5 through the blade transmission part 3. And a screwdriver sliding cavity 17 is transversely arranged at the tail of the knife body 1. A screwdriver fixing part 4 capable of sliding back and forth is provided in the screwdriver sliding cavity 17. The key point of the invention lies in that a sliding slot hole 6 is provided on the outer wall of the knife body 1. The screwdriver fixing part 4 is connected with a push key 11 through the sliding slot hole 6 and can move back and forth in the screwdriver sliding cavity 17 of the knife body 1 under the push of the push key 11, so that the tip of the screwdriver is received in the screwdriver sliding cavity 17 of the knife body 1 or exposed outside the screwdriver sliding cavity 17 of the knife body 1.

[0027] A chute piece 7 is arranged at the rear cavity part of the knife body 1, dividing the cavity part into two parts, namely a blade storage cavity and a screwdriver sliding cavity 17. A transverse chute 8 is provided on the chute piece 7. A fixing tube 9 is slidably fixed in the chute 8. The fixing tube 9 is used as the screwdriver fixing part 4, so that the screwdriver tip 14 is detachably arranged on the screwdriver fixing part 4. Usually, the chute piece 7 is made of a metal sheet, the chute 8 is pressed and formed, and then fixed in the knife body 1 with fasteners to facilitate manufacturing and assembly. An installation groove 10 for installing the push key 11 is provided at the inner end of the fixing tube 9. The push key 11 is installed in the installation groove 10. Protrusions 15 are provided on the outer walls on both sides of the push key 11. Correspondingly, concave parts 16 are provided on the groove walls of the installation groove 10 at corresponding positions for the protrusions 15 to move telescopically. And there is a spring 12 between the push key 11 and the installation groove 10. The spring 12 always applies an outward thrust. Positioning grooves 18 are distributed on the sides above and below the sliding slot hole 6 on the outer wall of the knife body 1. The positioning grooves 18 at least have a first positioning groove 19 in the extended state and a second positioning groove 20 in the retracted state, which are in positioning cooperation with the protrusions 15. In this way, when the user presses the push key 11 to move, the push key 11 overcomes the elastic force of the spring 12, and the protrusions 15 withdraw from the positioning grooves 18 and retract into the concave parts 16 of the installation groove 10, so as to realize that the push key 11 drives the fixing tube 9 to slide back and forth in the chute 8. And when the finger is released, the push key 11 under the action of the elastic force of the spring 12, the protrusions 15 protrude from the concave parts 16 of the installation groove 10 and enter into the positioning grooves 18, realizing the locking of the fixing tube 9. A fixing hole 13 is opened at the other end of the fixing tube 9. The cross section of the fixing hole 13 is usually polygonal and matches the outer wall of the screwdriver tip 14 to realize insertable fixation. Usually, the fixing hole 13 is preferably an equilateral hexagon. Correspondingly, the outer wall of the screwdriver tip 14 is also an equilateral hexagon. When the knife body 1 rotates, the fixing hole 13 also rotates synchronously, which can drive the screwdriver tip 14 to rotate.

[0028] When the user uses this product, the user can insert the required screwdriver bit 14 into the fixing hole 13 of the fixing tube 9 according to their own needs, press the push key 11, and translate the push key 11, thereby driving the fixing tube 9 to be pushed out, and the convex parts 15 on both sides of the push key 11 are buckled in the first gear groove 19, and then use the screwdriver bit 14.
