[0038] Example
[0039] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment provides a dual-purpose utility knife with a housing 10, a movable blade 11, and a fixed blade 12. The housing 10 has a receiving cavity 101, the opening of which (not shown in the figure) is located at the end of the housing 10. A sliding groove 102 is provided on one side of the housing 10, and a limiting part 103 is provided on the other side of the housing 10 opposite to the sliding groove 102. A movable blade 11 is disposed in the receiving cavity 101. A push key 111 is provided on the movable blade 11 to slide along the sliding groove 102 to drive the movable blade 11 to extend or retract from the opening. A limiting shaft 1111 is provided on the push key 111 to engage or disengage with the limiting part 103. A clearance notch 104 is provided on the top of the housing 10 to avoid the rotation of the movable blade 11. A fixed blade 12 is located in the receiving cavity 101 and is hinged to the axis of the movable blade 11. An elastic element 121, which can be a spring, is provided between the fixed blade 12 and the push key 111.
[0040] Specifically, the slide groove 102 and the limiting part 103 penetrate the housing 10 and are connected to the receiving cavity 101, so that one end of the push key 111 can slide along the slide groove 102, and the other end of the push key 111 is engaged or disengaged from the limiting part 103 through the limiting shaft 1111, and the limiting shaft 1111 can slide along the limiting part 103, thereby achieving precise control of the blade.
[0041] In use, the blades of the movable blade 11 and the fixed blade 12 are positioned opposite each other. When the push key 111 slides to a specific position, the limiting shaft 1111 separates from the limiting part 103. Under the action of the elastic element 121, the push key 111 automatically pops out from the slide groove 102, so that the movable blade 11 and the fixed blade 12 are at an angle. The clearance notch 104 on the top of the housing 10 allows the movable blade 11 to rotate at a certain angle. At this time, the housing 10 and the push key 111 can be used as the handle of the scissors. Pressing the push key 111 towards the housing 10 will cause the blades of the movable blade 11 and the fixed blade 12 to cut each other, thus realizing the function of scissors.
[0042] When the push key 111 is pressed back into the slide groove 102, and the push key 111 is slid to another specific position, the limiting shaft 1111 engages with the limiting part 103 again, and the movable blade 11 and the fixed blade 12 overlap in parallel. At this time, the utility knife resumes its normal cutting function and can be used as a utility knife.
[0043] In this way, users can flexibly switch between different usage modes according to actual needs, without having to carry extra scissors, reducing the burden of carrying them, enriching the functionality of the utility knife, and improving ease of use.
[0044] like Figure 3 and Figure 4As shown, in this embodiment, the limiting part 103 includes a first hole 1031, a second hole 1032 and a limiting groove 1033 that are sequentially connected along the length direction of the housing 10. The limiting groove 1033 extends to the bottom of the housing 10. The diameter of the first hole 1031 is smaller than the diameter of the limiting shaft 1111, and the diameter of the second hole 1032 is larger than the diameter of the limiting shaft 1111.
[0045] Specifically, when the push key 111 is pushed, the limiting shaft 1111 can slide along the limiting groove 1033, and the diameter of the end of the limiting shaft 1111 is greater than the width of the limiting groove 1033. Under the combined action of the elastic element 121 and the limiting shaft 1111, the push key 111 can slide stably along the limiting groove 1033 and the slide groove 102, preventing the push key 111 from coming off the slide groove 102 during the sliding process. When the push key 111 slides to the second hole 1032, since the diameter of the end of the limiting shaft 1111 is smaller than the diameter of the second hole 1032, the limiting shaft 1111 can separate from the second hole 1032, so that the push key 111 pops out of the slide groove 102 under the action of the elastic element 121, and the movable blade 11 rotates to the cutting position and is used as scissors. When the push button 111 is pressed back to the second hole 1032 and the push button 111 is pushed to the first hole 1031, since the end diameter of the limiting shaft 1111 is larger than the diameter of the first hole 1031, the limiting shaft 1111 engages with the first hole 1031 again, the push button 111 is stably locked, and the movable blade 11 and the fixed blade 12 are stacked in parallel, and it is used as a utility knife.
[0046] like Figure 5 As shown, in this embodiment, the bottom of the slide groove 102 is provided with a slot (not shown in the figure), and the bottom of the push key 111 is provided with a hook 1112 that engages with the slot. Specifically, when the blade retracts, the push key 111 engages with the slot to fix the position of the push key 111 and ensure the blade is safely stored; when it is needed, pressing the push key 111 separates it from the slot, allowing the push key 111 to slide freely within the slide groove 102 and extend the blade.
[0047] like Figure 5 As shown, in this embodiment, the push button 111 is provided with a concave surface 1113 for placing the hand. The design of the concave surface 1113 conforms to the ergonomic principle, and the curvature of the concave surface 1113 matches the natural curvature of the fingers, which improves the comfort of holding and pushing the push button 111, increases the operability, and ensures the precise extension and retraction of the blade.
[0048] like Figure 1 and Figure 2 As shown, in this embodiment, the push button 111 and / or the housing 10 are provided with anti-slip texture 1114, which enhances the stability of pushing and holding, prevents slippage during operation, and further improves the safety and reliability of use.
[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the housing 10 is provided with a hanging rope hole 105, which makes it convenient for users to hang, store or carry, saves space and is not easy to lose.
[0050] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
