Abstract
Description
Technical Field
[0001] The present invention provides a speed control tool structure with straight-in and straight-out, which mainly provides a secure assembly that can be visually identified during tool release, and can ensure safety after tool release, avoiding dangerous incidents. Background Technology
[0002] Wilderness survival skills are one of the essential skills for many enthusiasts who yearn for outdoor adventures, and folding knives are a common tool. Whether used for cutting, slicing, chopping, stabbing, or for self-defense, folding knives are very useful tools. When not in use, the blade can be folded into the handle for easy storage and carrying.
[0003] Please refer to patent number 268338, "Knife." This type of knife is the common folding knife we see today. However, with advancements in technology and the times, a major problem has emerged with this type of folding knife: it doesn't unfold quickly enough. In dangerous situations, one still has to pinch the blade with their fingers and pivot it relative to the handle. This action provides absolutely no time to react in a dangerous situation. Therefore, manufacturers have already improved the folding method, changing it to a spring-loaded type (the blade pops out when pressed). Please refer to patent number M628447, "Folding Knife with Elastic Rod Body." While folding knives are generally considered safe, this type can be dangerous due to accidental activation. To address this issue, new types of folding knives have been introduced to the market, primarily those that can be operated in a straight line (such as utility knives or spring knives). Straight-line knives allow for faster reaction time and better protection. However, these knives are subject to regulations and restrictions on their owners. This can sometimes prevent defenders from assessing the level of danger in time, leading to accidental injury to the user or others. Summary of the Invention
[0004] To address the issues of existing straight-in-straight-out knives that are prone to popping out and injuring the user, and make it difficult for the defender to predict or judge whether the knife-wielder intends to draw the knife, this invention provides a speed-controlled knife structure with a straight-in-straight-out feature. Before the user draws the knife, it can display the intention to draw it, allowing others to identify it and giving the defender time to protect themselves.
[0005] The technical solution adopted by this invention to solve its technical problem is: A speed-controlled cutting tool structure with straight-in and straight-out operation includes: a housing having an internal space, a cut on the end face of the housing, and a cutting exit on the side of the housing, wherein the internal space is connected to the cut and the cutting exit; an inner tool holder mounted in the internal space, with both ends of the inner tool holder assembled to the housing and having a track hole extending from the top to the bottom of the inner tool holder; and an upper guide plate mounted in the internal space and spaced apart from the position of the track hole of the inner tool holder, the upper guide plate having a slide rail corresponding to the cut, and a control part corresponding to the cut on the upper guide plate, the control part protruding from the cut and exposed. The outer casing includes a tool assembly comprising a cutting edge and a slider. Part of the slider slides within the track hole, while the other part protrudes from the track hole towards the side where the cut is located. The cutting edge is located on one side of the inner tool holder, opposite to the protruding part of the slider. One end of the cutting edge is assembled with the slider, while the other end faces the exit point. The slider moves along the shape of the track hole, causing the cutting edge to move through and retract from the exit point. A push control is partially located within the internal space, with the other part protruding from the outer casing. The push control is positioned between the upper guide plate and the slider, and is bolted through the cutting edge, the slider, and the slide hole by a shaft. The push control, when the upper guide plate moves towards the blade exit direction, contacts the part of the push control protruding from the outer shell during the movement, indirectly driving the slider to move along the track hole; two push blocks, which are respectively movably fastened to the upper guide plate and located at both ends of the slide, with part of the two push blocks fastened inside the slide, and the other part of the two push blocks protruding downward from the upper guide plate and located at the gap between the upper guide plate and the inner blade holder; additionally, an elastic element is installed in the slide and hooks the two push blocks at both ends; and a trigger latch is located between the slider and the upper guide plate, and is pierced by a central rod through the blade, the slider and the trigger latch, so that the trigger latch... When the blade pivots relative to the central rod and the cutting edge has not yet moved toward the exit point, the trigger latch is engaged at the end of the track hole. The control unit drives the upper guide plate to move toward the exit point, and the upper guide plate pushes the push block and push control near the exit point. The pushed push block moves and pulls the elastic element, generating elastic force. At the same time, the push control is pushed and indirectly drives the cutting edge to move. At this time, the trigger latch will release its engagement with the track hole and pivot. Then, due to the elastic force of the elastic element, it instantly pulls the push block away from the exit point, and pushes the slider with the push block, thereby allowing the cutting edge to quickly protrude from the exit point.
[0006] The user can control the blade's extension by applying force with their hand. By continuously applying force to the control unit, the user can control the timing of the blade's extension. When no force is applied, the elastic element, when pulled, instantly pulls the push block away from the blade's extension point, and this push block then pushes the slider, thereby quickly protruding the blade from the extension point. Therefore, the above description of the invention can be divided into two aspects. When the user possesses the invention, they primarily need to determine the timing of its use. Simply put, if the user is in a defensive position, they must assess the attacker's intent. The defender can draw their knife if the attack is highly dangerous, but cannot if the attack is not dangerous. However, the defender can show an intention to draw their knife to deter the attacker and protect their own safety. From another perspective, when the attacker holds this invention, the defender can observe whether the attacker pushes or presses the control unit to expose the blade, thereby determining whether the attacker intends to draw their knife. In this way, the defender can react in time to protect their own safety.
[0007] The beneficial effect of this invention is that before the user draws the knife, he / she can display the intention to draw the knife so that others can recognize it, thus giving the defender time to protect himself / herself. Attached Figure Description

[0020] Please see Figures 1 to 10As shown, Figures 1 to 4 This is a structural part of the present invention, and Figures 5 to 9As a schematic diagram of continuous operation, the present invention discloses a speed-controlled cutting tool structure with straight-in and straight-out operation, comprising: a rectangular three-dimensional outer shell 1, the outer shell 1 having an internal space 11, a cutting edge 12 on the end face of the outer shell 1, and a cutting edge 13 on the side face of the outer shell 1, wherein the internal space 11 is connected to the cutting edge 12 and the cutting edge 13 respectively; an inner tool holder 2, which is installed in the internal space 11, with both ends of the inner tool holder 2 assembled to the outer shell 1, and having a track hole 21 extending from the top end to the bottom end of the inner tool holder 2, with connecting plates 22 vertically protruding from both ends of the inner tool holder 2 and being assembled with the outer shell 1; and an upper guide plate 3, which is installed in the internal space 11 and spaced apart from the position of the inner tool holder 2 with the track hole 21, and the upper guide plate 3 having a slide rail 3. 1. The slide 31 and the cut 12 are interconnected and correspond to each other. The upper guide plate 3 is provided with a control part 32 corresponding to the cut 12. The control part 32 extends through the cut 12 and protrudes from the outer shell 1 for easy pressing and operation by the user. The knife assembly 4 includes a blade 41 and a slider 42. The slider 42 is partially slidable in the track hole 21, and the other part of the slider 42 protrudes from the track hole 21 towards the upper guide plate 3. The blade 41 is located on one side of the inner knife holder 2 and opposite to the protruding part of the slider 42. One end of the blade 41 is assembled with the slider 42, and the other end of the blade 41 faces the exit 13. The slider 42 moves along the hole of the track hole 21 and drives the blade 41 to move out and retract from the exit 13. Push control Component 5, partly located within the internal space 11, with another part of the push control 5 protruding from the outer shell 1. The push control 5 is positioned between the upper guide plate 3 and the slider 42, stacked above the slider 42, and connected to the blade 41, slider 42, and push control 5 via a shaft bolt 51. When the upper guide plate 3 moves towards the exit point 13, it contacts the protruding part of the push control 5, indirectly driving the slider 42 along the track hole 21, thus allowing the blade 41 to exit through the exit point 13. Two push blocks 6 are L-shaped pieces, movably fastened to the upper guide plate 3 and located at both ends of the slide rail 31. Parts of the two push blocks 6 are fastened within the slide rail 31, while the other parts protrude downwards from the upper guide plate 3. At the interval between the upper guide plate 3 and the inner knife holder 2, an elastic element 61 is installed in the slide 31 and hooks the two push blocks 6 at both ends. The elastic element 61 pulls the two push blocks 6 to move with elastic force. A trigger clip 7 is provided between the slider 42 and the upper guide plate 3 and is stacked on the slider 42. A shaft rod 71 passes through the blade 41, the slider 42 and the trigger clip 7 (the shaft bolt 51 and the shaft rod 71 in this invention are composed of three parts, including a sleeve, screw and nut. This is not a limitation on the composition of the shaft bolt 51 and the shaft rod 71). The trigger clip 7 pivots relative to the shaft rod 71. When the blade 41 has not yet moved toward the exit 13, the trigger clip 7 is partially locked at the end of the track hole 21.The control unit 32 moves the upper guide plate 3 towards the blade outlet 13, and the upper guide plate 3 pushes the push block 6 and the push control 5 near the blade outlet 13. The pushed push block 6, after moving, pulls the elastic element 61, generating elastic force. Simultaneously, the push control 5 is pushed, indirectly moving the blade 41. At this time, the trigger clip 7 releases its latch from the track hole 21 and pivots. Then, due to the elastic force of the elastic element 61, it instantly pulls the push block 6 away from the blade outlet 13, and the push block 6 pushes the slider 42, thereby allowing the blade 41 to quickly protrude from the blade outlet 13.
[0021] Based on the above explanation, please see Figures 5 to 9 The continuous motion diagram illustrates the process from not extending the blade to extending it. When the user wants to extend the blade, they simply need to cover the control unit 32 with their finger and apply force to push it. The control unit 32 will move along the opening direction of the cut 12. The movement of the control unit 32 controls the upper guide plate 3 to move towards the blade extension opening 13. During the movement of the upper guide plate 3, it simultaneously pushes the push block 6, which is close to the blade extension opening 13, to move together. The movement of the push block 6 simultaneously pulls the elastic element 61 to stretch elastically. As the upper guide plate 3 moves, the end away from the blade extension opening 13 will gradually approach and abut against the part of the push control 5 exposed in the outer shell 1. Under the continuous movement of the upper guide plate 3, the trigger latch 7 located between the upper guide plate 3 and the slider 42 will gradually pivot and release from the track hole 21. When the latch is engaged, the elastic force of the elastic element 61 is also stored to a certain strength. When the trigger latch 7 is completely disengaged from the latch of the track hole 21, the push block 6 close to the trigger latch 7 will be pulled by the elastic element 61 and instantly impact and push the trigger latch 7. Since the trigger latch 7 is connected to the slider 42, the blade 41 of the knife assembly 4 will instantly pass through the blade outlet 13 under the combined force of the user's pushing force and the elastic force of the elastic element 61. If you want to show the intention of the knife, you can use the force applied to the control part 32. As long as you continue to apply force to the control part 32 to control whether the knife is extended or not, the blade 41 of the knife assembly 4 will not pop out instantly, allowing the user to remain in a defensive state or to watch whether the holder intends to extend the knife and defend accordingly.
[0022] In addition to the above description of the main technical features of this invention, other technical features and structures are further detailed below. Please see below for details. Figure 3 , Figure 4As shown, to prevent the blade 41 from retracting into the internal space 11 on its own during use and causing danger, a positioning arm 8 is further configured to pivot on the inner blade holder 2 and near the blade outlet 13. The positioning arm 8 is located between the inner blade holder 2 and the upper guide plate 3. One end of a spring 81 is hooked to the end of the positioning arm 8 near the blade outlet 13, and the other end of the spring 81 is sleeved on the column block 111 in the internal space 11. The position of the column block 111 corresponds to that of the positioning arm 8. The control unit 32 drives the upper guide plate 3 to move towards the blade outlet 13. The upper guide plate 3 pushes against the positioning arm 8 to pivot and pulls the spring 81 to generate force. After the blade 41 passes through the blade outlet 13, the spring 81 releases its elasticity, causing the positioning arm 8 to abut against the slider 42 of the tool assembly 4, thereby fixing the retraction of the blade 41.
[0023] Continuing from the above explanation, please see [link / reference]. Figures 5 to 9 The continuous movement of the upper guide plate 3 and the positioning arm 8 is mainly achieved by utilizing the actuating post 82 provided on the positioning arm 8. Actuating blocks 33 are further protruding from both ends of the upper guide plate 3, extending in opposite directions and forming a trapezoidal shape. One actuating block 33 is used to push against the portion of the push control 5 protruding from the outer shell 1, while the other actuating block 33 corresponds to the position of the positioning arm 8. The actuating block 33 closer to the positioning arm 8 has an inclined guide surface 331 and a flat push surface 332. The flat push surface 332 is not at the same horizontal level as the side of the upper guide plate 3. When the upper guide plate 3 moves, the actuating post 82 movably abuts against the flat push surface 332, the inclined guide surface 331, and the peripheral surface of the upper guide plate 3. Before the upper guide plate 3 moves, the actuating pin 82 abuts against the flat push surface 332 and the spring 81 is stretched. When the upper guide plate 3 begins to move toward the cutting edge 13, the actuating pin 82 descends along the inclined guide surface 331 and falls onto the circumferential side of the upper guide plate 3. Utilizing the height difference between the flat push surface 332 and the circumferential side of the upper guide plate 3, the spring 81 releases its elastic force. With the continuous movement of the upper guide plate 3, after the cutting edge 41 of the tool assembly 4 is instantly extended, the movement of the slider 42 pushes the positioning arm 8 to swing and then locks against the circumferential side of the slider 42. In this way, the position of the cutting edge 41 after it is extended can be positioned, and the problem of the cutting edge 41 retracting on its own during use can be avoided.
[0024] For further explanation, please see Figures 2 to 4As shown above, the method for controlling the blade extension speed has been explained. This invention also has another function to control the blade extension speed. This is mainly achieved by further cutting a side sliding opening 14 at the protruding position of the push control 5 on the outer shell 1. This side sliding opening 14 connects to the internal space 11, and one end of the push control 5 protrudes through the side sliding opening 14 and is exposed outside the outer shell 1. This allows the protruding part of the push control 5 to move along the opening of the side sliding opening 14. Additionally, at the end of the push control 5 protruding from the outer shell 1... An adjusting block 52 is installed and locked to the push control 5 with a screw 53. The screw 53 passes through the push control 5 and movably abuts against the outer shell 1. The screw 53 is looser than the push control 5 to reduce contact with the outer shell 1 and reduce friction, thereby allowing the cutting edge of the tool assembly 4 to quickly pass through the exit opening 13. Conversely, when the screw 53 is tighter than the push control 5 to increase contact with the outer shell 1 and increase friction, the cutting edge 41 of the tool assembly 4 will reduce its exit speed.
[0025] Furthermore, the relationship between the trigger clip 7 and the track hole 21 has been explained above. Its main purpose is to prevent the blade 41 from popping out unnecessarily and causing danger. However, a more detailed technical feature is that the track hole 21 further includes a straight section 211 and an arc-shaped clip section 212. Please see... Figure 3 , Figure 4 As shown, the arc-shaped buckle segment 212 is connected to the straight section 211 and forms a locking protrusion 213 at the connection. The locking protrusion 213 has an arc-shaped guide surface 214. The trigger latch 7 has a stop portion 72 protruding from the arc-shaped buckle segment 212 corresponding to the track hole 21. When the tool assembly 4 has not yet slid, the stop portion 72 abuts against the locking protrusion 213. When the upper guide plate 3 pushes the push control 5 to move, the stop portion 72 of the trigger latch 7 is guided along the arc-shaped guide surface 214 of the locking protrusion 213. The trigger clip 7 pivots around the pivot rod 71. After the stop part 72 releases from the latching protrusion 213, the slider 42 can move along the path of the straight section 211 and drive the blade 41 through the exit hole 13. Conversely, when the blade is retracted, the stop part 72 of the trigger clip 7 will latch onto the wall of the arc clip section 212. Only when the user indirectly applies force to the upper guide plate 3 will the stop part 72 of the trigger clip 7 be guided back to the arc clip section 212 along the arc guide surface 214 and latch.
[0026] Please see Figure 3 , Figure 4As shown, in the design of the push control 5, in order to make the user control the cutting speed of the blade 41 of the tool assembly 4 more stable, the push control 5 further includes a first section 54 and a second section 55 in the part between the upper guide plate 3 and the slider 42. The first section 54 is connected to the second section 55 at one end and is L-shaped. The other end of the first section 54 protrudes from the outer shell 1 and is bent upward. The spindle 71 and the bolt 51 both pass through the first section 54 and the second section 55 of the push control. By setting the spindle 71 and the bolt 51, the push control 5 can be stably connected with the slider 42. During the movement of the upper guide plate 3, the push control 5 can also be stably driven.
[0027] Finally, to provide users with stable control over the knife, a control element 10 is further provided, connected to the portion of the control unit 32 that extends through the cut 12. The control element 10 is cone-shaped, with a flat top. Textures 101 are provided on both sides of the flat top of the control element 10, primarily to provide friction for the user's fingers when pressing, facilitating stable control of the control element 10. Users can adjust the applied force and the timing of release according to their needs and knife-throwing intentions. (See [link to relevant documentation]). Figure 1 As shown.
[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.

The upper guide plate is installed in the built-in space and is spaced apart from the position where the inner knife holder has a track hole. The upper guide plate is cut with a slide, and the slide corresponds to the cut. The upper guide plate is provided with a control part corresponding to the cut, and the control part protrudes from the cut and is exposed in the outer shell. The tool assembly includes a cutting edge and a slider. Part of the slider is slidably disposed in the track hole, and the other part of the slider protrudes from the track hole toward the side where the cut is located. The cutting edge is disposed on one side of the inner tool holder and opposite to the protruding part of the slider. One end of the cutting edge is assembled with the slider, and the other end of the cutting edge faces the exit opening. The slider moves along the hole pattern of the track hole and drives the cutting edge to move out and retract into the exit opening. The push control is partially located in the built-in space, while the other part of the push control protrudes from the outer shell. The push control is located between the upper guide plate and the slider, and the blade, the slider and the push control are connected by a shaft. When the upper guide plate moves towards the blade outlet, it contacts the part of the push control that protrudes from the outer shell during the movement, so that it indirectly drives the slider to move along the track hole. Two push blocks are movably fastened to the upper guide plate and located at both ends of the slide. Part of the two push blocks are fastened inside the slide, while the other part of the two push blocks protrudes downward from the upper guide plate and is located at the gap between the upper guide plate and the inner knife holder. In addition, an elastic element is installed inside the slide and hooks the two push blocks at both ends. The trigger clip is located between the slider and the upper guide plate, and is inserted through the blade, the slider and the trigger clip by a central rod, so that the trigger clip pivots relative to the central rod. When the blade has not yet moved toward the exit point, the trigger clip is partially engaged with the end of the track hole. The control unit moves the upper guide plate toward the blade outlet, and the upper guide plate pushes the push block and push control near the blade outlet. The push block, when moved, pulls the elastic element and generates elastic force. At the same time, the push control is pushed and indirectly drives the blade to move. At this time, the trigger clip will release its latch from the track hole and pivot. Then, due to the elastic force of the elastic element, it instantly pulls the push block away from the blade outlet, and pushes the slider with the push block, thereby allowing the blade to quickly protrude from the blade outlet.
2. The speed control tool structure with straight-in and straight-out operation according to claim 1, characterized in that, The positioning arm is further positioned on the inner tool holder and close to the blade outlet. The positioning arm is located between the inner tool holder and the upper guide plate. One end of a spring is hooked to the end of the positioning arm near the blade outlet, while the other end of the spring is sleeved on the column block in the internal space. The control unit drives the upper guide plate to move towards the blade outlet. The upper guide plate pushes against the positioning arm pivot and pulls the spring to generate stored force. After the blade passes through the blade outlet, the spring releases its elastic force, causing the positioning arm to abut against the slider of the tool assembly, thereby fixing the retraction of the blade.
3. The speed control tool structure with straight-in and straight-out operation according to claim 1, characterized in that, The outer shell is further cut with a side sliding opening corresponding to the protruding position of the push control. One end of the push control protrudes through the side sliding opening and is exposed outside the outer shell. In addition, an adjustment block is installed on the end of the push control that protrudes from the outer shell, and the adjustment block is locked to the push control with a screw. The screw passes through the push control and is movably pressed against the outer shell. The screw is looser than the push control to reduce contact with the outer shell and reduce friction, so that the blade of the tool assembly can quickly pass through the exit point. Conversely, when the screw is tighter than the push control to increase contact with the outer shell and increase friction, the blade of the tool assembly will reduce the exit speed.
4. The speed control tool structure with straight-in and straight-out operation according to claim 1, characterized in that, The track hole further includes a straight section and an arc-shaped section. The arc-shaped section is connected to the straight section and forms a locking protrusion at the connection. The locking protrusion has an arc-shaped guide surface. The trigger latch has a stop protruding from the arc-shaped section of the track hole. When the tool assembly has not slid, the stop abuts against the locking protrusion. When the upper guide plate pushes the push control to move, the stop of the trigger latch is guided along the arc-shaped guide surface of the locking protrusion. The trigger latch pivots around the shaft rod. After the stop is released from the locking protrusion, the slider can move along the path of the straight section and drive the cutting edge to pass through the exit hole.
5. The speed control tool structure with straight-in and straight-out operation according to claim 1, characterized in that, The push control device, located between the upper guide plate and the slider, further includes a first section and a second section. The first section is connected to the second section at one end and is L-shaped. The other end of the first section protrudes from the outer shell. The shaft rod and the bolt both pass through the first section and the second section of the push control device.
6. The speed control tool structure with straight-in and straight-out operation according to claim 2, characterized in that, The upper guide plate has two additional protruding stop blocks at its two ends, each extending in opposite directions. One stop block is used to push against the part of the control component that protrudes from the outer shell, while the other stop block corresponds to the position of the positioning arm. The stop block closer to the positioning arm has an inclined guide surface and a flat push surface. The flat push surface is not at the same horizontal height as the side of the upper guide plate. In addition, the positioning arm has a stop post protruding from the stop block it is close to. When the upper guide plate moves, the stop post moves against the flat push surface, the inclined guide surface, and the peripheral surface of the upper guide plate. When the upper guide plate moves toward the cutting edge, the stop post first abuts against the flat push surface and the spring is stretched. Then it descends along the inclined guide surface and falls to the peripheral surface of the upper guide plate. At this time, the spring releases its elastic force. When the blade of the tool assembly is instantly cut out, the movement of the slider pushes against the swing of the positioning arm and then locks against the peripheral surface of the slider.
7. The speed control tool structure with straight-in and straight-out operation according to claim 1, characterized in that, Furthermore, the control component is connected to the part of the control unit that protrudes through the cut, and the top surface of the control component is textured to facilitate stable pushing and controlling of the control component.
