Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a utility knife with a multi-angle adjustable cutting head. Background Technology

[0002] As a common hand tool, the utility knife is widely used in many fields such as advertising production, DIY crafts, packaging disassembly, and model making. With its sharp blade and flexible operation, it can meet the cutting needs of various materials in different scenarios, such as paper, plastic, cloth, and thin wood.

[0003] A utility knife with publication number CN222945616U includes a blade core, a blade holder slidably disposed within the blade core, and a blade disposed on the blade holder. The blade core is characterized by a hollow internal structure with a blade outlet. A groove is formed on one end face of the blade core, and multiple slots are formed along the length of the groove wall. A push button and an elastic element are disposed on the blade holder. When the push button is not pressed, the elastic element is engaged in a slot to fix the relative position of the blade holder. This utility model achieves equal-width cutting of long items by attaching the hook of an existing measuring tape to the utility knife. However, because the blade of this utility model can only extend and retract, the angle of the cutting blade cannot be adjusted, making it inconvenient to adjust according to different usage needs.

[0004] Therefore, it is necessary to design a utility knife with a multi-angle adjustable cutting head that allows for convenient adjustment of the cutting head at multiple angles, making it easy to use and flexible according to needs. Utility Model Content

[0005] To overcome the shortcomings of existing technologies where the blade can only extend and retract and the angle of the cutting blade cannot be adjusted, making it inconvenient to adjust according to different usage needs, this utility model provides a utility knife with a multi-angle adjustable cutting head that allows for convenient multi-level angle adjustment of the cutting head, facilitating flexible adjustment according to needs and making it easy to use.

[0006] Technical solution: A utility knife with a multi-angle adjustable cutting head, comprising a handle, a fixing plate, a rotating shaft, a cutting head, an adjustment component, and a locking component. The left side of the handle is connected to two fixing plates, and the left side of the fixing plates is rotatably connected to the rotating shaft. The cutting head is connected to the rotating shaft. The handle is provided with an adjustment component that allows for convenient multi-angle adjustment of the cutting head. The left side of the handle is provided with a locking component that can retract and lock the cutting head.

[0007] Furthermore, it is particularly preferred that the handle has multiple grooves.

[0008] Furthermore, it is particularly preferred that the cutting head has a mating hole on the left side.

[0009] Furthermore, it is particularly preferred that the adjustment assembly includes a rotating column, an external gear ring, a gear, a locking tooth, a synchronous toothed belt, and a first spring. The rotating column is rotatably and slidably connected to the right side of the handle. An external gear ring is connected to the middle of the rotating column. A gear is rotatably connected to the inner side of the right side of the handle. A gear is also connected to the rotating shaft. A locking tooth is connected to the inner side of the gear. A synchronous toothed belt is wound around the gears. A first spring is sleeved between the rotating column and the handle.

[0010] Furthermore, it is particularly preferred that the rotary column also includes a knob, with the knob connected to the upper side of the rotary column.

[0011] Furthermore, it is particularly preferred that the assembly also includes a locking component, which includes a locking frame, a second spring, a locking post, and a locking member. The locking frame is slidably connected to the upper left part of the handle, and the second spring is connected between the locking frame and the handle. The locking post is connected to the lower middle part of the locking frame and engages with the handle. The locking member is connected to the lower left part of the locking frame and engages with the rotating shaft.

[0012] Beneficial effects: 1. This utility model, by pressing the knob downwards, causes the rotating column to move downwards, so that the outer gear ring engages with the locking teeth. Then, by rotating the knob, the rotating column is driven to rotate, causing the gear to rotate. The gear meshes with the synchronous tooth belt, causing the rotating shaft to rotate, which in turn drives the cutting head to rotate. This achieves the effect of conveniently adjusting the cutting head to multiple angles, making it easy to adjust flexibly according to needs and convenient to use.

[0013] 2. This utility model uses a rotating shaft to rotate the cutting head and retract it between the fixed plates. Then, the knob is released, so that the outer gear ring is no longer engaged with the locking teeth. Next, the locking frame is released, which drives the locking pin and locking piece to move downward, so that the locking piece engages with the rotating shaft. This achieves the effect of limiting the cutting head and preventing accidental knob rotation, thus avoiding accidental injury to personnel caused by the blade rotating out.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] A utility knife with a multi-angle adjustable cutting head, such as Figure 1 and Figure 2 As shown, it includes a handle 1, a fixing plate 2, a rotating shaft 3, a cutting head 4, an adjustment component, and a locking component. The handle 1 has ten grooves for easy gripping. The left side of the handle 1 is connected to two fixing plates 2, and the left side of the fixing plates 2 is rotatably connected to the rotating shaft 3. The cutting head 4 is connected to the rotating shaft 3. The left side of the cutting head 4 has a docking hole for easy docking. The handle 1 is equipped with an adjustment component, and the left side of the handle 1 is equipped with a locking component.

[0021] like Figures 1-3 As shown, the adjustment assembly includes a rotating column 5, a knob 51, an external gear ring 6, a gear 7, a locking tooth 8, a synchronous toothed belt 9, and a first spring 10. The rotating column 5 is rotatably and slidably connected to the right side of the handle 1. The knob 51 is connected to the upper side of the rotating column 5. The external gear ring 6 is connected to the middle of the rotating column 5. The gear 7 is rotatably connected to the inner side of the right side of the handle 1. The gear 7 is also connected to the rotating shaft 3. The locking tooth 8 is connected to the inner side of the gear 7. The synchronous toothed belt 9 is wound around the gears 7. The first spring 10 is sleeved between the rotating column 5 and the handle 1.
