The blade disengagement structure 10 of the present application is used to achieve mechanical separation of the blade 110 and the handle 120 to avoid direct contact of the hand with the blade 110, while improving the disengagement efficiency of the blade 110. In one embodiment, the knife of the present application is a scalpel 100, and the disengagement node of the blade 110 is postoperative disengagement. In addition to being applicable to scalpels 100, the blade disengagement structure 10 of the present application is also applicable to knives in which the blade 110 and the handle 120 are connected by a snap-on structure.

[0063] Attached Figure 1 1 is a schematic diagram of the structure of the scalpel 100 of the present application. Figure 2 This is a schematic diagram of the structure of the blade 110 of the present application. Figure 1 And attached Figure 2 As shown, the scalpel 100 of the present application includes a blade 110 and a handle 120, and the blade 110 and the handle 120 are connected by a clamping method. The handle 120 of the present application includes a mounting section 121 and a hand-held section 122, and the mounting section 121 is located at one end of the hand-held section 122, and the mounting section 121 is fixedly connected to the hand-held section 122. The width of the mounting section 121 is smaller than the width of the hand-held section 122, and the mounting section 121 and the hand-held section 122 are transitionally connected through a connection, and the width of the connection is gradually increased from the mounting section 121 to the hand-held section 122. The mounting section 121 is formed with a protrusion toward one side of the blade 110, and the protrusion is circumferentially provided with a groove, and the mounting section 121 is mounted on the blade 110 through the protrusion, and part of the blade 110 is clamped in the groove.

[0064] In one embodiment, the mounting section 121 and the hand-held section 122 are manufactured in one piece.

[0065] Please refer to the attached Figure 1 And attached Figure 2 As shown, the blade 110 of the present application includes a mounting area 111 and a contact area 112. The mounting area 111 is a through hole that runs through the blade 110 and an area around the through hole. When the blade 110 is mounted on the handle 120, the protrusion of the mounting section 121 is located in the mounting area 111. When the blade 110 is mounted on the mounting section 121, the mounting area 111 contacts the mounting section 121, the contact area 112 is protruded relative to the mounting section 121, and the contact area 112 does not contact the mounting section 121. Therefore, when the blade 110 is detached, the initial separation of the blade 110 and the handle 120 can be achieved by means of the raised area 112.

[0066] The blade 110 includes an upper surface 113 and a lower surface 114 . The upper surface 113 and the lower surface 114 are located at upper and lower sides of the blade 110 , respectively.

[0067] The blade 110 includes a first end 115 and a second end 116. The first end 115 of the blade 110 is smaller than the second end 116. When the blade 110 is mounted on the mounting section 121, the second end 116 of the blade 110 is spaced apart from the handheld section 122.

[0068] Please refer to the attached Figure 3 To Attachment Figure 8 As shown, the first direction X of the present application refers to the length direction of the blade detachment structure 10, that is, the direction from left to right of the blade detachment structure 10 or the direction from right to left of the blade detachment structure 10. In the present application, the blade entry 211 of the first accommodating cavity 210 is arranged to the right relative to the blade exit 212 of the first accommodating cavity 210, and the blade exit 212 of the first accommodating cavity 210 is arranged to the left relative to the blade entry 211 of the first accommodating cavity 210. The second direction Y of the present application refers to the height direction of the blade detachment structure 10, that is, the direction from top to bottom of the blade detachment structure 10 or the direction from bottom to top of the blade detachment structure 10. In the present application, the first connecting member 611 is arranged above the second connecting member 612, and the second connecting member 612 is arranged below the first connecting member 611. The width direction of the present application refers to the width direction of the blade detachment structure 10, that is, the direction from left to right of the blade detachment structure 10 or the direction from right to left of the blade detachment structure 10.

[0069] Attached Figure 3 1 is a schematic diagram of the structure of the blade separation structure 10 of the present application. Figure 4 This is another schematic diagram of the structure of the blade separation structure 10 of the present application. Figure 3 And attached Figure 4 As shown, the blade detachment structure 10 of the present application includes a detachment body 200, and the detachment body 200 of the present application is a long strip structure. A first accommodating cavity 210 is arranged in the detachment body 200 of the present application along the first direction X. When the blade 110 is separated from the handle 120, the blade 110 is always located in the first accommodating cavity 210. In the present application, the first accommodating cavity 210 is arranged through the detachment body 200, so the first accommodating cavity 210 is respectively provided with a blade entry 21 and a blade exit 212 at both ends along the first direction X. The width of the blade entry 211 and the blade exit 212 of the present application in the third direction Z is greater than the width of the installation section 121 of the blade 110 and the handle 120, but less than the width of the hand-holding section 122 of the handle 120.

[0070] During specific use, the blade disengagement structure 10 is generally tilted, and the specific tilting method is that the blade entry 211 is located above the blade exit 212 in the height direction, so that when the blade 110 is separated from the handle 120, the blade 110 automatically slides out of the first accommodating cavity 210 from the blade exit 212.

[0071] In one embodiment, the detachable body 200 of the present application is a rectangular parallelepiped.

[0072] In one embodiment, any cross section of the first receiving cavity 210 of the present application is rectangular.

[0073] Please refer to the attached Figure 3 And attached Figure 4 As shown, a first outlet 400 is provided in the detachable body 200 of the present application along the first direction X. The first outlet 400 of the present application is located at the bottom of the first accommodating cavity 210 along the second direction Y. The first accommodating cavity 210 is connected to the outside in the second direction Y through the first outlet 400.

[0074] During specific use, the mounting section 121 of the handle 120 is separated from the first accommodating cavity 210 through the first outlet 400 .

[0075] Please refer to the attached Figure 3 And attached Figure 4 As shown, the blade disengagement structure 10 of the present application further includes a blocking block 300. The setting of the blocking block 300 ensures that the blade 110 is retained in the first accommodating cavity 210 when the blade 110 and the handle 120 are disengaged. In the present application, the blocking block 300 is set in the first accommodating cavity 210, and further the blocking block 300 is set on one side of the blade inlet 211. The first outlet 400 of the present application also passes through the blocking block 300. The blocking block 300 of the present application will be attached.

[0076] In one embodiment, blocking blocks 300 are disposed on both sides of the first outlet 400 .

[0077] Please refer to the attached Figure 3 And attached Figure 4 As shown, the detachable body 200 of the present application is also provided with a first avoidance groove 410, which is located in the extension direction of the first outlet 400 along the first direction X, and is provided on the side of the first outlet 400 close to the blade inlet 211, and the width of the first avoidance groove 410 along the third direction Z is greater than the width of the first outlet 400 along the third direction Z. Since the connection between the mounting section 121 of the handle 120 and the hand-held section 122 is a transition connection, the width of the connection between the mounting section 121 of the handle 120 is greater than the width of the normal mounting section 121 of the handle 120, so that the mounting section 121 of the handle 120 can be normally moved out of the first outlet 400 when the blade 110 is detached from the handle 120, the width of the first outlet 400 in the third direction Z, that is, the width of the first avoidance groove 410, is deliberately increased.

[0078] In one embodiment, the width of the first avoidance groove 410 in the third direction Z is gradually reduced from the blade entry 211 side to the blade exit 212 side.

[0079] Please refer to the attached Figure 3 And attached Figure 4 As shown, the blade disengagement structure 10 of the present application also includes a contact block 500, which is arranged in the first accommodating cavity 210 along the first direction X. The contact block 500 is arranged to increase the contact surface 510 with the blade 110 after the blade 110 is tilted, so as to avoid the blade 110 from being broken due to uneven force after the blade 110 is tilted. At the same time, the blocking block 300 may not be arranged in the present application, and the friction between the contact block 500 and the blade 110 is used to separate the blade 110 from the handle 120 when the handle 120 is pulled out. In the present application, the contact block 500 will be arranged in the attached Figure 6 And attached Figure 7 Further described in .
