When the handle is held by hand to replace the blade, the fingers (the thumb) can directly touch and operate the unlocking part, which is convenient to control. Since the fingers (the thumb) are easy to touch and operate the unlocking part, the force and burden of the fingers (the thumb) to operate the unlocking part are also reduced.

[0007] Preferably, the locking mechanism comprises a swing lever, the swing lever is biased by the elastic force of a first elastic element to lock the blade, and the unlocking part is operated to overcome the elastic force of the first elastic element to make the swing lever reversely biased to unlock the blade. The swing lever of this structure has a large swing range, the locking is reliable, the swing lever can completely leave the blade when unlocked, and the jamming is avoided.

[0008] Preferably, the blade is provided with a first locked part, the swing lever is provided with a first locking part, the swing lever is biased by the elastic force of the first elastic element to interlock the first locking part with the first locked part, and the operation of the unlocking member overcomes the elastic force of the first elastic element to bias the swing lever in the opposite direction to unlock the first locking part from the first locked part. The elastic force of the first elastic element ensures that the first locking part and the first locked part are interlocked.

[0009] Preferably, the first locked part is a groove on the back of the blade, and the first locking part is a hook on the swing lever. This allows the swing lever to swing without obstruction.

[0010] Preferably, the blade is provided with a second locked part facing backward, and the holder is provided with a second locking part facing forward, and when the blade is inserted into the mounting part from front to back, the second locked part and the second locking part are inserted together.

[0013] Preferably, the holder has a notch to expose more cutting parts when the blade is assembled to the holder. Various structural forms of blades configured on the holder can perform their cutting functions.

[0014] Preferably, the unlocking member is a moving member protruding from the side surface of the handle and moving along the surface of the handle. Accordingly, it is easy to operate with the thumb, such as pushing and holding.

[0015] Preferably, the handle includes an inner plate and a face plate, and the unlocking member is positioned and guided between the inner plate and the face plate and protrudes from the face plate. This not only ensures easy operation of the unlocking member, but also appropriately conceals the unlocking member, ensuring the flexibility and structural reliability of the unlocking member, further avoiding the folding path of the holder and preventing accidental activation of the unlocking member when the holder is folded.

This not only allows the holder to be flexibly folded, but also ensures compact structure and avoids increasing the size of the tool.

[0017] Preferably, a second elastic element is arranged to act on the unlocking member, and the elastic force of the second elastic element urges the unlocking member to move away from the swing lever. When the unlocking member is operated to be unlocked, the elastic force of the second elastic element is overcome. This avoids the elastic force of the second elastic element from counteracting the elastic force of the first elastic element, and ensures that the elastic force of the first elastic element urges the first locking part to interlock with the first locked part.

[0018] Preferably, the second elastic element is a curved linear spring arranged between the inner plate and the face plate and acting on the unlocking member. The linear spring occupies a small space, and avoids the thickness of the handle from being excessively increased due to the arrangement of the second elastic element.

[0019] Preferably, one end of the curved linear spring is sleeved on the pivot, and the other end is connected to the unlocking member. In view of this structure, since the curved linear spring is limited between the inner plate and the face plate, and both ends of the curved linear spring are constrained and cannot move out of the working position. The assembly structure of the curved linear spring is simple, and a support structure for supporting the second elastic element does not need to be arranged on the handle, thereby reducing the processing cost. In the profile of the handle, this assembly mode can make the curved linear spring have a larger profile, and give it a proper elasticity, so as to exert sufficient elastic force on the unlocking member. When the unlocking member is operated, it is beneficial to overcome the elastic force, and when the unlocking member is released, it can be reset by the elastic force.

[0020] Preferably, the unlocking member is arranged to move in the front-rear direction, and the rear end of the swing lever is matched with the unlocking member by means of a slope. Therefore, it is easy to move the unlocking member by the thumb.

[0062] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0063] like Figures 1-5 As shown, the folding knife includes a handle 100, a blade holder 200, and a blade. The blade holder 200 is rotatably mounted to the front end of the handle 100 via a pivot 400 for folding. The blade holder 200 is provided with a mounting portion 201 and a locking mechanism, which locks the blade to the mounting portion of the blade holder. In particular, the front end of the handle 100 is provided with an unlocking member 500 that is linked to the locking mechanism. Operating the unlocking member unlocks the locking mechanism from locking the blade, allowing the blade to be removed and installed. Therefore, the blade can be replaced by operating the unlocking member when needed. Figures 1-13 The image shows the situation where the first cutting tool 310 is installed on the tool holder 200. Figure 14 The illustration shows the configuration of the second blade 320 mounted on the tool holder. Figure 15 The structure of the third blade 330 is shown. The first, second, and third blades shown in the figure are merely exemplary representations; in other embodiments, blades with other structural forms may also be used. The first, second, and third blades may be stored together in a box as spare blades.

[0064] The folding knife has the front end of the handle provided with an unlocking member linked with the locking mechanism, and the unlocking member is operated to unlock the locking mechanism to the blade to remove and mount the blade. Compared with the prior art in which the unlocking member of the locking mechanism is arranged on the handle, the distance between the unlocking member and the hand holding the handle is shortened, and when the blade is replaced by holding the handle with the hand, the unlocking member can be directly touched and operated by the finger (thumb), and the operation is convenient. Since the finger (thumb) is easy to touch and operate the unlocking member, the force and burden of the finger (thumb) are also reduced.

[0065] As shown in Figures 4-5 , Figures 9-11 , Figures 13-14 The locking mechanism includes a swing lever 260, which is biased to lock the blade by the elastic force of a first elastic element 270, and the unlocking member 500 is operated to overcome the elastic force of the first elastic element 270 to reverse the swing lever 260 to unlock the blade. Specifically, in the structure shown in the figure, the handle 200 includes a first plate 210 and a second plate 220 spaced apart, and a first gasket 230, a second gasket 240 and a third gasket 250 are arranged between the first plate and the second plate, and the first plate, the second plate and the corresponding gasket are fastened together by transverse fasteners such as rivets, screws to ensure the structural strength of the handle and support the blade when the blade is installed. The first plate 210 and the second plate 220 form an installation portion 201, and the front end of the installation portion is open to allow the blade to be inserted into the installation portion from the open end or pulled out of the installation portion. The swing lever 260 is assembled between the first plate 210 and the second plate 220 by a pin shaft. The first elastic element 270 is a linear spring, a part of which is fixed in a slot of the first gasket 230, and the upper end of the linear spring is supported on the lower part of the rear end of the swing lever 260. In this structure, the swing lever has a large swing range, the locking is reliable, and the blade can be completely separated during unlocking to avoid jamming. In order to limit the swing lever from being excessively biased by the elastic force of the first elastic element, the second gasket 240 located on the upper side of the rear end of the swing lever 260 and the third gasket 250 located on the front end of the swing lever can limit the swing lever.

[0066] Figures 1-13 The first blade 310 shown in Figure 14 The second blade 320 shown in Figure 15The third blade 330 is provided with a first locked part 301, and the swing lever 260 is provided with a first locking part 261. The first locking part 261 is interlocked with the first locked part 301 by the elastic force of the first elastic element 270. The operation of the unlocking part overcomes the elastic force of the first elastic element to make the swing lever swing reversely to unlock the first locking part 261 from the first locked part 301. The elastic force of the first elastic element ensures the interlocking of the first locking part 261 and the first locked part 301. Specifically, the first locked part 301 is a slot with its opening facing upward on the back of the blade, and the first locking part 261 is a downwardly extending hook at the front end of the swing lever. The swing lever of this structure is not hindered when the hook is swung out of the slot. Figure 14 The second blade 320 is provided with consistent structures at both ends, and is symmetrical as a whole. Therefore, the second blade can be installed upside down to the holder. For this purpose, the slot as the first locked part is two.

[0067] Figures 1-13 The first blade 310, Figure 15 The two ends of the third blade 330 remain different, and they realize different cutting functions from the second blade. Therefore, only one slot as the first locked part is configured. However, in order to make the installed blade more stable, the first blade and the third blade are both provided with a second locked part 302 facing backward. The holder is provided with a second locking part 251 facing forward, which is formed at the front end of the third gasket 250. When the blade is inserted into the installation part from front to back, the second locked part and the second locking part are inserted together. Accordingly, more structural forms of blades are configured for the folding knife, and reliable structural guarantees are provided for the installation of these blades. Specifically, the second locked part 302 is a slot, and the second locking part 251 is a convex part. The interlocking and unlocking of the two are facilitated. In particular, the convex part is located at the front end of the holder. Accordingly, the convex part is more easily interlocked and unlocked with the slot, and is prevented from being hindered.

[0068] As Figures 11-12 The holder 200 is provided with a notch 202 to expose more cutting parts 303 when the blade is assembled to the holder. The provision of the notch is suitable for the installation of any structural form of blade to the holder, so that various structural forms of blade configured to the holder can play their cutting roles. In Figures 6-7 , Figures 9-10 and Figure 13 The outline of the blade is indicated by a dashed line, and the outline of the holder is indicated by a solid line to highlight that more cutting parts 303 are exposed when the blade is assembled to the holder.

[0069] As Figure 1As shown, the unlocking member 500 is a moving member protruding from the side surface of the handle 100 and moving along the surface of the handle. Accordingly, it is convenient to operate with the thumb, such as pushing. In the structure shown, the first panel 110 has a through hole, and the unlocking member 500 protrudes through the through hole 111 for operation. The first panel 110 is flat, and the surface of the handle is embodied as the surface of the first panel. In other embodiments, the panel can be curved, and the movement of the moving member along the surface of the handle is embodied as movement in the direction perpendicular to the pivot axis (left-right direction), such as forward-backward movement or upward-downward movement.

[0070] As shown, Figures 4-5 The handle 100 includes a first inner panel 120, a second inner panel 140, a first panel 110, a second panel 150, and a spacer 130. The spacer 130 is located between the first inner panel 120 and the second inner panel 140, the first panel 110 is attached to the outside of the first inner panel 120, and the second panel 150 is attached to the outside of the second inner panel 140. The first panel 110, the first inner panel 120, the spacer 130, the second inner panel 140, and the second panel 150 are fastened together by fasteners such as rivets. The knife holder 200 is assembled between the first inner panel 120 and the second inner panel 140 by the pivot 400, and a containing space is maintained between the first inner panel and the second inner panel for containing the knife holder after being folded. The unlocking member 500 is positioned and guided between the first inner panel 120 and the first panel 110 and protrudes from the first panel. It not only ensures easy operation of the unlocking member, but also appropriately conceals the unlocking member, ensures the flexibility of the unlocking member and the reliability of the structure, further avoids the folding path of the knife holder, and avoids affecting the folding of the knife holder and accidental touching of the unlocking member when the knife holder is folded.

[0071] Further, the front end of the first inner panel 120 is provided with an arc-shaped through hole 121, the rear end of the swing lever 260 extends into the front end of the handle and extends out of the handle to the side (left side in the figure) as a bent portion 262, the bent portion 262 passes through the arc-shaped through hole and is located between the first inner panel 120 and the first panel 110 and cooperates with the unlocking member 500. This not only enables the knife holder to be flexibly folded, but also ensures compact structure and avoids increasing the size of the knife. Since the first panel and the first inner panel are attached together, a corresponding recess 112 is provided on the inner side (right side) of the first panel for accommodating and guiding the unlocking member and accommodating the bent portion and the second elastic element described below. Figure 5 The shape and depth of the recess 112 depend on the structure and range of movement of the bent portion, the unlocking member, and the second elastic element described below.

[0072] As shown, Figures 4-7 , Figure 10 , Figures 12-13As shown, a second elastic element 600 is configured to act on the unlocking member 500, and the elastic force of the second elastic element 600 urges the unlocking member 500 to move away from the swing lever. When the unlocking member is operated to be unlocked, the elastic force of the second elastic element is overcome. This avoids the elastic force of the second elastic element from counteracting the elastic force of the first elastic element, and ensures that the elastic force of the first elastic element urges the first locking portion to interlock with the first locked portion. Specifically, the second elastic element 600 is a curved linear spring located between the first inner plate and the first panel and acting on the unlocking member. The linear spring occupies a small space, and avoids excessive increase in the thickness (left-right direction dimension) of the handle due to the configuration of the second elastic element.

[0073] In particular, one end of the curved linear spring is sleeved on the pivot 400, and the other end is connected to the unlocking member 500. In view of this structure, since the curved linear spring is limited between the first inner plate and the first panel, and both ends of the curved linear spring are constrained and cannot be moved out of the working position. The assembly structure of the curved linear spring is simple, and it is not necessary to provide a support structure on the handle to support the second elastic element, thereby reducing the processing cost. Within the profile of the handle, this assembly mode can make the curved linear spring have a larger profile, and give it appropriate elasticity, so as to exert sufficient elastic force on the unlocking member. When the unlocking member is operated, it is beneficial to overcome the elastic force, and when the unlocking member is released, it can be reset by the elastic force.

[0074] As shown in Figure 4 , Figures 6-7 , Figure 10 , Figures 12-13 , the unlocking member 500 is configured to move in the front-back direction, and the rear end of the swing lever 260 cooperates with the unlocking member 500 through the inclined surface 263 formed on the bent portion 262. Therefore, as shown by the straight arrow in Figure 13 , the unlocking member 500 is pushed forward by the thumb to move the unlocking member forward, and the forward movement of the unlocking member urges the rear end of the swing lever 260 to swing downward through the inclined surface 263. Through the swing of the swing lever as shown by the arc arrow in Figure 13 , the hook at the front end of the swing lever can be disengaged from the first locked portion 301, and the blade is unlocked. At this time, the blade can be pulled out, and a new blade can be inserted into the blade holder. When the unlocking member is released, the unlocking member and the swing lever are reset, and the installed blade is locked in the blade holder.
