One end of the first conducting member and one end of the second conducting member are electrically connected to the power supply assembly. The ring contact member is arranged on a blade body. The ring contact member is arranged around a rotating shaft. The ring contact member is insulatedly connected to the blade body. The other end of the first conducting member is arranged at the rotating shaft. The first conducting member is arranged to slide against the ring contact member when the handle rotates on the rotating shaft. The other end of the second conducting member is arranged at the rotating shaft. The second conducting member is arranged to slide against the blade body when the handle rotates on the rotating shaft. The light emitting assembly is arranged on the blade body.

[0041] The above-mentioned electric contact structure makes the light-emitting component arranged on the knife body, i.e. makes the knife body have the light-emitting function, and in the structure for realizing the light-emitting function of the light-emitting component, the first conducting member and the second conducting member are arranged on the knife handle in a spaced manner, and one end of the first conducting member and one end of the second conducting member are electrically connected with the power supply component, i.e. the power supply component is arranged on the knife handle, and the first conducting member and the second conducting member are arranged on the knife handle, which preferably ensures the structural stability of the power supply component, the first conducting member and the second conducting member arranged on the butterfly knife. In addition, the annular contact member is insulatedly connected with the knife body, i.e. the annular contact member is arranged on the knife body, which preferably ensures the structural stability of the annular contact member on the butterfly knife. Furthermore, the annular contact member is arranged around the rotating shaft, the first conducting member is used to slide against the annular contact member when the knife handle rotates on the rotating shaft, and the second conducting member is used to slide against the knife body when the knife handle rotates on the rotating shaft, i.e. the arrangement of the first conducting member, the second conducting member and the annular contact member does not affect the smooth rotation of the knife handle and the knife body. Furthermore, in the case of ensuring the structural stability and the smooth rotation, the aesthetic appearance of the butterfly knife is improved.

[0042] It should be noted that the main body of the knife handle is made of an insulating material, for example, plastic. The power supply component is a battery pack structure, and the first conducting member and the second conducting member are independently connected to the battery pack through a conductor or a wire. The first conducting member and the second conducting member are used as positive and negative conducting members to cooperate with the knife body and the annular contact member to make the light-emitting component connected with the battery pack in a path, thereby realizing that the butterfly knife can emit light when the conductor rotates, and effectively improving the aesthetic appearance of the butterfly knife.

[0043] In order to better understand the electric contact structure of the present application, the electric contact structure of the present application is further explained as follows:

[0044] Please refer to Figures 1-2The electric contact structure 10 of one embodiment includes a power supply assembly 100, an electric contact assembly 200, and a light emitting assembly 300. The power supply assembly 100 is configured to be mounted on a handle. The electric contact assembly 200 includes a first conductor 210, a second conductor 220, and a ring contact 230. The first conductor 210 and the second conductor 220 are configured to be disposed on the handle, and one end of the first conductor 210 and one end of the second conductor 220 are electrically connected to the power supply assembly 100. The ring contact 230 is configured to be disposed on a blade body, and the ring contact 230 is configured to surround a rotation shaft. The ring contact 230 is insulated from the blade body. The other end of the first conductor 210 is configured to be located at the rotation shaft, and the first conductor 210 is configured to slide and abut against the ring contact 230 when the handle rotates on the rotation shaft. The other end of the second conductor 220 is configured to be located at the rotation shaft, and the second conductor 220 is configured to slide and abut against the blade body when the handle rotates on the rotation shaft. The light emitting assembly 300 is configured to be disposed on the blade body, and the light emitting assembly 300 is electrically connected to the ring contact 230 and the blade body.

[0045] The electric contact structure 10 described above is configured such that the light emitting assembly 300 is disposed on the blade body, i.e., such that the blade body has a light emitting function. In the structure for achieving the light emitting function of the light emitting assembly 300, the first conductor 210 and the second conductor 220 are configured to be disposed on the handle with a space therebetween, and one end of the first conductor 210 and one end of the second conductor 220 are electrically connected to the power supply assembly 100, i.e., the power supply assembly 100 is disposed on the handle, and the first conductor and the second conductor are disposed on the handle. This preferably ensures the stability of the structure in which the power supply assembly 100, the first conductor 210, and the second conductor 220 are disposed on the butterfly knife. In addition, the ring contact 230 is insulated from the blade body, i.e., the ring contact 230 is disposed on the blade body. This preferably ensures the stability of the structure in which the ring contact 230 is disposed on the butterfly knife. Furthermore, the ring contact 230 is configured to surround the rotation shaft, the first conductor 210 is configured to slide and abut against the ring contact 230 when the handle rotates on the rotation shaft, and the second conductor 220 is configured to slide and abut against the blade body when the handle rotates on the rotation shaft. This is configured such that the disposition of the first conductor 210, the second conductor 220, and the ring contact 230 does not affect the smooth rotation of the handle and the blade body. This preferably improves the aesthetic appearance of the butterfly knife while ensuring the stability of the structure and the smooth rotation.

[0046] Please refer to Figures 2-5In one of the embodiments, the first conducting member 210 comprises a conducting part 211 and an abutting part 212, both of which are arranged on the handle, one end of the conducting part 211 is electrically connected with the power supply assembly 100, the other end of the conducting part 211 is arranged at the rotating shaft, and the conducting part 211 is connected with the abutting part 212 at the end close to the rotating shaft, and the abutting part 212 is arranged to slide and abut with the annular contact member 230 when the handle rotates on the rotating shaft.

[0047] Please refer to Figures 2-5 In one of the embodiments, the abutting part 212 comprises a containing body 2121 and an elastic body 2122, both of which are arranged at the rotating shaft, and the containing body 2121 is connected with the conducting part 211, and the elastic body 2122 is connected with the containing body 2121, the elastic body 2122 is arranged to slide and abut with the annular contact member 230 when the handle rotates on the rotating shaft, and the elastic body is contracted when it abuts with the annular contact member 230. It can be understood that, in order to better meet the needs of the user, the tightness of the butterfly knife when rotating has differences, and thus when the tightness of the butterfly knife when rotating is low, the tightness of the handle and the blade of the butterfly knife is small, and the distance between them is large, and when the tightness of the butterfly knife when rotating is high, the tightness of the handle and the blade of the butterfly knife is large, and the distance between them is small, and in order to make the universal of the electric contact structure 10, the abutting part 212 is the containing body 2121 and the elastic body 2122, the containing body 2121 is arranged to assemble the elastic body 2122 on the conducting part 211, and the elastic body 2122 has the ability of elastic deformation, and thus in the case of different tightness of the butterfly knife, it can achieve good abutting strength with the annular contact member 230, that is, the elastic body 2122 has a certain pressing force on the annular contact member 230, and thus better ensures the universality and electrical connection stability of the electric contact structure 10, and thus better ensures the functional stability of the light emitting assembly 300 of the butterfly knife, and thus better improves the aesthetic property of the butterfly knife.

[0048] In one of the embodiments, the accommodating body is provided with an accommodating groove, and the accommodating groove is open towards the annular contact member. Further, the elastic body comprises an elastic component and an abutting component, both of which are arranged in the accommodating groove, the elastic component is clamped between the bottom of the accommodating groove and the abutting component, the elastic component is in sliding connection with the accommodating body in the accommodating groove, the abutting component at least partially protrudes from the accommodating groove, and the abutting component is used to slide and abut with the annular contact member when the handle rotates on the rotating shaft. The elastic component is contracted when the abutting component abuts with the annular contact member, which preferably ensures the elastic deformation ability of the elastic body. In different cases of tightness of the butterfly knife, the annular contact member has good abutting strength, which preferably ensures the functional stability of the light-emitting assembly of the butterfly knife, and further preferably improves the aesthetic appearance of the butterfly knife.

[0049] In one of the embodiments, the abutting component is a ball, which is clamped in the accommodating groove and is in rotational connection with the accommodating body. It can be understood that, since the handle and the body of the butterfly knife are in rotational connection, when the friction strength between the abutting component and the annular contact member is high, the rotational smoothness of the butterfly knife is affected, and the user experience is affected. Therefore, in order to better improve the user experience, the abutting component is a ball in the present application, which effectively reduces the abutting area when the abutting component abuts with the annular contact member, and the ball realizes the rolling abutment of the abutting component on the annular contact member, and also realizes the rolling arrangement of the abutting component on the accommodating groove. Therefore, the rolling smoothness of the ball on the annular contact member is preferably ensured, the rotational smoothness of the butterfly knife is preferably ensured, and the user experience is preferably improved.

[0050] Please refer to Figures 2-5 In one of the embodiments, the second conducting member 220 comprises a second conducting part 221 and a second abutting part 222, both of which are arranged on the handle. One end of the second conducting part 221 is electrically connected with the power supply assembly 100, and the other end of the second conducting part 221 is arranged at the rotating shaft, and the second conducting part 221 is connected with the second abutting part 222 near one end of the rotating shaft. The second abutting part 222 is used to slide and abut with the body when the handle rotates on the rotating shaft.

[0051] In one of the embodiments, the structure of the second abutting part of the second conducting member is the same as that of the abutting part of the first conducting member, which preferably ensures the abutting stability and rolling smoothness of the second abutting part on the body, and further preferably improves the aesthetic appearance of the butterfly knife and the user experience.

[0052] In one of the embodiments, the second conducting part of the second conducting member and the conducting part of the first conducting member are both in the shape of a long strip, and are both used for the electrical conduction of the power supply assembly.

[0053] Please refer to Figures 2-5 In one of the embodiments, the annular contact piece 230 comprises an annular part 231 and a conductive part 232, both of which are arranged on the knife body and insulatedly connected with the knife body, the annular part 231 is arranged around the rotation shaft, and the annular part 231 is used to abut against the first conducting piece 210 when the handle rotates on the rotation shaft, one end of the conductive part 232 is connected with the annular part 231, and the other end of the conductive part 232 is electrically connected with the light-emitting assembly 300.

[0054] In one of the embodiments, the annular contact piece further comprises an insulating part, which is sleeved on the annular part and the conductive part, and the annular part and the conductive part are insulatedly connected with the knife body through the insulating part, which reduces the short circuit problem of the power supply assembly and effectively utilizes the existing structure, thereby improving the aesthetics of the butterfly knife while simplifying the structure of the butterfly knife.

[0055] In one of the embodiments, the annular contact piece is subjected to insulation treatment, such as oxidation passivation treatment, to form a passivation insulating layer on the surface of the annular contact piece, thereby improving the aesthetics of the butterfly knife while simplifying the structure of the butterfly knife.

[0056] It can be understood that excessive increase of the conductive structure on the handle will greatly increase the structural volume of the handle, and the increase of the structural volume of the handle, i.e. the increase of the length or width of the handle, will affect the hand feeling of the user, i.e. the increase of the length or width of the handle will cause interference between the rotation of the handle and the hand of the user, thereby affecting the experience of the user, and in order to better ensure the experience of the butterfly knife, the second abutting part of the second conducting piece is directly abutted against the knife body in the present application, which reduces the arrangement of the electrically conductive structure between the light-emitting assembly and the second abutting piece, thereby effectively simplifying the butterfly knife and effectively ensuring the experience of the user.

[0057] Please refer to Figures 2-5 In one of the embodiments, the annular part 231 and the conductive part 232 are integrally formed, which improves the connection stability and compactness of the annular part 231 and the conductive part 232, thereby better ensuring the structural stability and compactness of the annular contact piece 230 and reducing the processing procedures of the annular contact piece 230, thereby improving the processing efficiency of the annular contact piece 230.

[0058] Please refer to Figure 3 and Figure 5In one of the embodiments, the electric contact structure 10 further comprises an auxiliary light-emitting component 400, which is arranged on the peripheral wall of the handle and is electrically connected with the power supply component 100, thereby further improving the appearance of the handle and further improving the appearance of the butterfly knife.

Further, in this embodiment, the electric contact structure 10 comprises the power supply component 100, the electric contact component 200, and the light-emitting component 300. The power supply component 100 is installed on the handle 30. The electric contact component 200 comprises the first and second conductive members 210 and 220 and the annular contact piece 230. The first and second conductive members 210 and 220 are arranged on the handle 30 in a spaced manner, one end of the first conductive member 210 and one end of the second conductive member 220 are electrically connected with the power supply component 100, the annular contact piece 230 is arranged on the blade body 20 and surrounds the rotating shaft 40, the annular contact piece 230 is insulatedly connected with the blade body 20, the other end of the first conductive member 210 is located at the rotating shaft 40 and is in sliding abutment with the annular contact piece 230 when the handle 30 rotates on the rotating shaft 40, and the other end of the second conductive member 220 is located at the rotating shaft 40 and is in sliding abutment with the blade body 20 when the handle 30 rotates on the rotating shaft 40. The light-emitting component 300 is arranged on the blade body 20 and is electrically connected with the annular contact piece 230 and the blade body 20, respectively.

[0061] The above butterfly knife 10A adopts the electric contact structure 10, which improves the aesthetic appearance of the butterfly knife 10A while ensuring the structural stability and smooth rotation of the butterfly knife 10A.

[0062] Please see Figure 6 and Figures 8-11 In one embodiment, the rotating shaft 40 includes a bearing 41, a threaded member 42, and a screw 43. The threaded member 42 is arranged on the handle 30 and is rotationally connected to the handle 30. One end of the threaded member 42 protrudes from the handle 30. The screw 43 is screwed with the threaded member 42, and at least part of the screw 43 protrudes from the threaded member 42. The threaded member 42 protruding from the handle 30 and the screw 43 protruding from the threaded member 42 are respectively in abutment with the two side walls of the handle 30. The inner ring of the bearing 41 is sleeved on the peripheral wall of the threaded member 42, and the outer ring of the bearing 41 is connected with the blade body 20. It can be understood that the screw 43 is used to adjust the rotation tightness of the handle 30 on the rotating shaft 40, that is, the screw 43 is used to adjust the tightness of the handle 30 and the blade body 20. The tightness of the handle 30 and the blade body 20 can be adjusted, which is convenient for the user to adjust the rotation tightness of the handle 30 and the blade body 20, thereby improving the universality and use convenience of the butterfly knife 10A.

[0063] In one embodiment, a snap ring is arranged on the screw, and the snap ring of the screw is clamped on the threaded member when the screw is screwed with the threaded member. It can be understood that the screw is prone to loosening during the rotation of the handle and the blade body, which affects the rotation of the butterfly knife, and thus a snap ring is arranged on the screw. Even if the screw loosens during the rotation of the handle and the blade body, it will loosen to the snap ring at most, thereby preventing the handle and the blade body from further loosening and improving the use safety of the butterfly knife.

[0064] It can be understood that users have different requirements for the tightness of the butterfly knife during rotation. Some users require the butterfly knife to be relatively loose during rotation to achieve fast and easy rotation, while some users require the butterfly knife to be relatively tight during rotation, so that they can better control the rotation amplitude of the butterfly knife to complete more difficult butterfly knife rotations. Therefore, in order to better adapt the butterfly knife to the usage habits and purposes of more users, two screws are used to adjust the tightness of the handle of the butterfly knife. However, this also causes the tightness of the butterfly knife to become looser and looser during rotation, which makes it difficult for the butterfly knife to maintain consistent tightness during long-term use. This not only affects the user's operation experience, but also greatly affects the user's effective control of the rotation of the butterfly knife, which may cause the butterfly knife to injure the user. In order to better maintain the tightness of the butterfly knife during use, please see Figure 6 , Figure 7 ,Figure 13 And Figure 14 In one of the embodiments, at least one reinforcing hole 31 is formed on the shank 30, the reinforcing hole 31 is arranged in the same direction as the rotation shaft 40, and a reinforcing fastener 50 is arranged on each reinforcing hole 31. The reinforcing hole 31 is arranged away from the power supply assembly 100, the first conducting element 210, and the second conducting element 220, the reinforcing fastener 50 penetrates through the corresponding reinforcing hole 31, and the reinforcing fastener 50 abuts against the two side walls of the shank 30, respectively. It can be understood that the reinforcing hole 31 is formed on the shank 30, and the reinforcing fastener 50 is added at the reinforcing hole 31, which cooperates with the screw 43 at the rotation shaft 40 to improve the maintenance effect of the tightness of the shank 30 on the rotation shaft 40, thereby effectively improving the user experience.

[0065] It can also be understood that even if the reinforcing fastener further strengthens the maintenance of the tightness of the butterfly knife during rotation, the tightness of the shank of the butterfly knife will still change slowly during a long time of use of the butterfly knife due to the friction between the shank and the screw during rotation of the butterfly knife, thereby requiring the user to constantly adjust the tightness of the butterfly knife. Therefore, in order to better maintain the tightness of the butterfly knife during use, in one of the embodiments, a plurality of shaft beads are arranged on the screw of the screw element, the plurality of shaft beads are arranged on the screw in a spaced manner and used for abutting against the side surface of the shank, and the plurality of shaft beads are arranged around the outer periphery of the screw element. Each shaft bead is clamped on the screw, each shaft bead is in rotational connection with the screw, and each shaft bead abuts against the side wall of the shank. It can be understood that the shaft bead effectively reduces the friction strength between the screw and the screw element, thereby reducing the change in the tightness of the shank during rotation of the shank, achieving effective maintenance of the tightness of the butterfly knife during use, and effectively improving the user experience.

[0066] Please refer to Figure 6 And Figure 7 In one of the embodiments, at least one reinforcing hole 31 is arranged near the rotation shaft 40, which better improves the maintenance effect of the tightness of the shank 30 on the rotation shaft 40 by the cooperation of the reinforcing fastener 50 and the screw 43, thereby effectively improving the user experience.

[0067] Please refer to Figure 6 And Figure 7 In one of the embodiments, the number of reinforcing holes 31 is two or more, and the two or more reinforcing holes 31 are arranged on the shank 30 in a spaced manner, which better improves the maintenance effect of the tightness of the shank 30 on the rotation shaft 40 by the cooperation of the reinforcing fastener 50 and the screw 43, thereby effectively improving the user experience.

[0068] Please refer to Figure 6 AndFigure 7 In one of the embodiments, the number of reinforcing holes 31 is three, and the three reinforcing holes 31 are evenly arranged on the handle 30, which can better improve the maintaining effect of the reinforcing fastener 50 cooperating with the screw 43 to improve the tightness of the handle 30 on the rotating shaft 40, thereby effectively improving the user's experience.

[0069] Please refer to Figure 6 , Figure 7 and Figure 12 In one of the embodiments, the reinforcing fastener 50 includes a reinforcing screw 51 and two reinforcing screws 52, the reinforcing screw 51 is arranged at the reinforcing hole 31, and the two reinforcing screws 52 are located at the two ends of the reinforcing screw 51. Each reinforcing screw 52 is screwed with the reinforcing screw 51, and each reinforcing screw 52 at least partially protrudes from the reinforcing hole 31. The portions of the two reinforcing screws 52 protruding from the reinforcing hole 31 are in opposite abutment with the two side walls of the handle 30. Without interfering with the adjustment of the rotating tightness of the handle 30 and the tool body 20, the reinforcing screw 52 cooperates with the screw 43 to better achieve the effective maintenance of the tightness of the handle 30 on the rotating shaft 40, thereby effectively improving the user's experience.

The plurality of auxiliary shaft beads are arranged on the side of the auxiliary screw for abutment with the side wall of the handle, and the plurality of auxiliary shaft beads are arranged around the outer periphery of the auxiliary screw. Each auxiliary shaft bead is clamped on the auxiliary screw, and each auxiliary shaft bead is in rotational connection with the auxiliary screw. Each auxiliary shaft bead is in abutment with the side wall of the handle. It can be understood that the reinforcing shaft bead cooperates with the shaft bead to further effectively reduce the friction strength of the screw and the screw, thereby reducing the change of the tightness of the handle during rotation of the handle, that is, the effective maintenance of the tightness of the butterfly knife during use is achieved, thereby effectively improving the user's experience.
