[0035] See also Figure 1-Figure 5 , shows a preferred embodiment of the present invention, a knife twisting structure, comprising:

[0036] A push knob 1 having a mounting portion 111; and

[0037] The nighttime self-luminous structure 2 is disposed on the mounting portion 111 , and at least a portion of the nighttime self-luminous structure 2 is exposed from the push knob 1 .

[0038] The knife twist structure of the present invention provides a night-time self-luminous structure 2 on the mounting portion 111 of the push knob 1, and at least a portion of the night-time self-luminous structure 2 is exposed outside the push knob 1, so that the push knob 1 has a night-time self-luminous function, which can illuminate and indicate the push knob 1, thereby facilitating rapid and accurate positioning of the push knob 1 under low-light conditions at night, making it more convenient for the folding knife with the knife twist structure to be used outdoors at night. At the same time, since the night-time self-luminous structure 2 automatically illuminates at night and does not require a power source, the structure is simple and the cost is low, which can reduce the cost of the knife twist structure and thus reduce the cost of the folding knife.

[0039] See also Figure 1-Figure 3 In one embodiment, the push button 1 includes:

[0040] The first twist body 11 is provided with a protruding portion 112, a first connecting portion 113, and a second connecting portion 114. The protruding portion 112, the first connecting portion 113, and the second connecting portion 114 are sequentially arranged in the left-right direction of the push knob 1. The protruding portion 112 is configured to be disposed outside one of the left and right side walls of the blade body 3 and is configured to cooperate with a finger. The first connecting portion 113 is configured to penetrate the connecting hole 31 of the blade body 3; and

[0041] A second twisting body 12 is connected to the second connecting portion 114 and is configured to be disposed outside the other of the left and right side walls of the blade body 3. The second twisting body 12 is configured to cooperate with a finger;

[0042] The mounting portion 111 is provided on the first twist body 11 or the second twist body 12, or both the first twist body 11 and the second twist body 12 are provided with the mounting portion 111. Thus, during installation, the nighttime self-luminous structure 2 can be first installed on the first twist body 11 or the second twist body 12, then the first twist body 11 can be installed on the blade body 3, and finally the second twist body 12 can be installed on the second connecting portion 114. This makes it easy to install the push knob 1 on the blade body 3, and the installation operation is simple and convenient.

[0043] See also Figure 1-Figure 3 In one embodiment, the second twist body 12 is sleeved on the outer peripheral wall of the second connecting portion 114;

[0044] The mounting portion 111 includes a mounting hole 1111, which passes through the first twisted body 11 on both sides. The night-time self-luminous structure 2 is arranged in the mounting hole 1111 to realize that the night-time self-luminous structure 2 is built into the first twisted body 11, which can improve the connection stability between the night-time self-luminous structure 2 and the first twisted body 11, and at the same time enable the night-time self-luminous structure 2 to transmit light out of the protrusion 112 and the second twisted body 12 when emitting light, thereby illuminating the protrusion 112 and the second twisted body 12, making it convenient for users to quickly locate the protrusion 112 and the second twisted body 12.

[0045] In one embodiment, the nighttime self-luminous structure 2 extends from one end of the mounting hole 1111 to the other end to increase the brightness of the protrusion 112 and the second twisting body 12 , making it easier for users to quickly locate the protrusion 112 and the second twisting body 12 .

[0046] In one embodiment, the night-time self-luminous structure 2 is interference fit with the mounting hole 1111 so that the night-time self-luminous structure 2 can be reliably fixed in the mounting hole 1111. While the installation is simple and convenient, the night-time self-luminous structure 2 can be installed on the push button 1 without a connection structure, thereby simplifying the structure.

[0047] Of course, in other embodiments, the night-time self-luminous structure 2 is loosely matched with the mounting hole 1111, and a glue layer is provided between the night-time self-luminous structure 2 and the mounting hole 1111, which fixes the night-time self-luminous structure 2 and the first twisted body 11 together.

[0048] Of course, in other embodiments, the nighttime self-luminous structure 2 can also be fixed in the mounting hole 1111 by fasteners such as screws and rivets.

[0049] Of course, in other embodiments, the mounting portion 111 may include a mounting groove or a mounting plane, as long as the push knob 1 and the nighttime self-luminous structure 2 can be fixedly connected together.

[0050] See also Figure 2 and Figure 3 In one embodiment, the nighttime self-luminous structure 2 includes:

[0051] A first nighttime luminous body 21 is inserted into one end of the mounting hole 1111 close to the protrusion 112; and

[0052] The second night-time luminous body 22 is inserted into the end of the mounting hole 1111 near the second twisted main body 12. That is, the night-time self-luminous structure 2 is composed of the first night-time luminous body 21 and the second night-time luminous body 22 which are separately provided. During installation, the first night-time luminous body 21 can be inserted into the end of the mounting hole 1111 near the protrusion 112, and the second night-time luminous body 22 can be inserted into the end of the mounting hole 1111 near the second twisted main body 12 in sequence, and the installation of the night-time self-luminous structure 2 can be completed. This can effectively avoid the problem of difficulty in assembling the night-time self-luminous structure 2 due to the long length of the mounting hole 1111 and the night-time self-luminous structure 2 in the left-right direction, and can greatly improve the assembly efficiency of the night-time self-luminous structure 2.

[0053] In one embodiment, the outer peripheral wall of the second connecting portion 114 is provided with an external thread structure, and the second twist body 12 has a threaded hole 121, and the threaded hole 121 is adapted to the external thread structure, that is, the second twist body 12 is connected to the second connecting portion 114 through a threaded connection. While the connection operation is simple, the second twist body 12 can be reliably fixed to the second connecting portion 114, and the structural reliability is higher.

[0054] Of course, in other embodiments, the second torsion body 12 may also be connected to the second connecting portion 114 by fasteners such as screws, bolts, and rivets.

[0055] In one embodiment, the outer diameter of the protrusion 112 and the outer diameter of the second twist body 12 are both larger than the outer diameter of the first connection part 113. In this way, the protrusion 112 can be abutted against one of the left and right side walls of the blade body 3, and the second twist body 12 can be abutted against the other of the left and right side walls of the blade body 3, thereby achieving a left and right limiting effect on the first connection part 113, so that the first connection part 113 is reliably connected to the connection hole 31 on the blade body 3, thereby achieving a reliable fixation of the push twist 1 and the blade body 3 together.

[0056] In one embodiment, the nighttime self-luminous structure 2 includes a tritium gas tube or a luminous tube. Both the tritium gas tube and the luminous tube can realize automatic luminescence without power supply. The structure is simple and practical, the cost is low, and the cost of the knife twisting structure and the folding knife can be reduced.

[0057] A preferred embodiment of the present invention provides a folding knife, comprising the above-mentioned knife-opening twist structure.

[0058] The folding knife of the present invention adopts the above-mentioned knife twist structure, and is also based on the arrangement of a night-time self-luminous structure 2 on the mounting portion 111 of the push knob 1, and at least a portion of the night-time self-luminous structure 2 is exposed outside the push knob 1, so that the push knob 1 has a night-time self-luminous function, which can illuminate and indicate the push knob 1, thereby facilitating the rapid and accurate positioning of the push knob 1 in low-light conditions at night, making it more convenient for the folding knife with the knife twist structure to be used outdoors at night.
