Abstract
Description
Technical Field
[0001] This utility model relates to the field of outdoor knife manufacturing technology, and more specifically, to a straight knife with a concealed blade handle. Background Technology
[0002] Fixed-blade knives are indispensable multi-functional tools for outdoor activities. They combine cutting, chopping, peeling, and emergency demolition functions, making them especially suitable for processing food, clearing obstacles, or dealing with emergencies. Fixed-blade knives are also frequently used by tourists because they can be sheathed for easy carrying during travel and outdoor activities. However, most traditional fixed-blade knives use sheaths for sheathing, which makes it difficult to quickly open and close the blade, thus hindering their ability to handle unexpected outdoor events and limiting their operational capabilities.
[0003] Therefore, in view of this, we will study and improve the existing technology to provide a straight knife with a concealed handle, in order to achieve a more practical value. Utility Model Content
[0004] In view of the problems of existing straight blades, this utility model provides a straight blade with a concealed handle to solve the problems mentioned in the background art.
[0005] This utility model is implemented as follows: This utility model provides a straight knife with a concealed handle. The concealed handle straight knife includes a straight blade and a handle locking mechanism movably connected to the straight blade. The straight blade has a cutting edge at its front end, a button hole in its middle, a screw hole above the right of the button hole, a spindle hole vertically below the button hole, and a handle and screw hole at the tail end of the straight blade. Each screw hole on the straight blade contains a threaded stop pin. The handle locking mechanism includes a left handle plate, a right handle plate, a left handle locking plate, a right handle locking plate, a button, a spring, and a threaded spacer sleeve. The left and right handle plates have corresponding screw holes. Screws pass through the screw holes to connect the left and right handle plates to the two ends of the threaded stop pins on the straight blade, forming a handle for gripping. The left handle plate also has a button hole and a button limiting groove. The button has a protruding edge and is installed in the button hole of the straight blade, with the right end of the button... A recessed groove is provided between the two sides, and a spring is placed in the groove. The right end of the spring contacts the right handle plate, accumulating elastic force. Under the action of the spring, the protrusion of the button protrudes to the left in the button hole of the left handle plate and contacts the finger. The left and right handle locking plates are provided with screw holes and spindle holes respectively. Threaded spacer sleeves are provided in the screw holes of the left and right handle locking plates, and spindle nuts are provided in the spindle holes. The left and right handle locking plates are connected to the two ends of the threaded spacer sleeves by screws. The left and right handle locking plates are also connected to the two ends of the spindle nuts by spindle screws, forming a swing arm that can swing left and right. The left handle locking plate is also provided with a first locking groove and a second locking groove. The first and second locking grooves contact the protruding edge of the button. When the straight knife is in the active state, by pressing the button, the button that is locked in the first or second locking groove is disengaged. The swing arm rotates synchronously around the spindle hole of the straight knife blade, thereby realizing the opening or closing of the straight knife.
[0006] Furthermore, both ends of the threaded spacer sleeve, threaded stop pin, and spindle nut are provided with threaded holes for connection with screws and spindle screws.
[0007] The beneficial effects of this utility model are: Because this utility model uses a handle locking mechanism on the straight blade, the swing arm of the handle locking mechanism can swing left and right to hide the cutting edge inside the swing arm. By controlling the button to contact the first locking groove and the second locking groove, the straight blade can be opened quickly and the cutting edge can be quickly stored in the swing arm, which effectively improves the working efficiency of the straight blade and solves the problems mentioned in the technical background.

[0014] Please see Figure 1-7This utility model provides a straight knife with a concealed handle. The straight knife includes a straight blade 11 and a handle locking mechanism 12 movably connected to the straight blade 11. The straight blade 11 has a cutting edge 6 at its front end, a button hole 15 in its middle, a screw hole 16 above and to the right of the button hole 15, and a spindle hole 17 vertically below the button hole 15. The tail end of the straight blade 11 has a handle 7 and a screw hole 16. Each screw hole 16 on the straight blade 11 is fitted with a threaded stop pin 18. The handle locking mechanism... The structure 12 includes a left handle plate 35, a right handle plate 36, a left handle locking plate 37, a right handle locking plate 38, a button 39, a spring 40, and a threaded spacer sleeve 41. The left handle plate 35 and the right handle plate 36 are respectively provided with screw holes 16. Screws 22 are used to pass through the screw holes 16 to connect the left handle plate 35 and the right handle plate 36 to both ends of the threaded stop pins 18 provided on the straight blade 11. Combined with the handle 7, it forms a handle 21 for gripping. The left handle plate 35 is also provided with a button hole 15 and a button limiting groove 23. The button 39 has a protruding edge 24 and is installed in the button hole 15 of the straight blade 11. Furthermore, a groove 25 is recessed in the middle of the right end of button 39, and spring 40 is placed in the groove 25. The right end of spring 40 contacts the right handle plate 36 and accumulates elastic force. Under the action of the spring, the protrusion 1 of button 39 protrudes to the left in the button hole 15 of left handle plate 35 and contacts the finger. Screw holes 16 and spindle holes 17 are correspondingly provided on the left handle locking plate 37 and right handle locking plate 38. Threaded spacer sleeves 41 are provided in the screw holes 16 of the left handle locking plate 37 and right handle locking plate 38, and spindle nuts 2 are provided in the spindle holes 17. The left handle locking plate 37 and right handle locking plate 38 are made of screws. The pin 22 is connected to both ends of the threaded spacer sleeve 41. The left handle locking plate 37 and the right handle locking plate 38 are both connected to both ends of the main shaft nut 2 by the main shaft screw 20, forming a swing arm 3 that can swing left and right. The left handle locking plate 37 is also provided with a first locking groove 4 and a second locking groove 5. The first locking groove 4 and the second locking groove 5 are in contact with the protruding edge 24 of the button 39. When the straight knife is in the active state, by pressing the button 39, the button 39 that is locked in the first locking groove 4 or the second locking groove 5 is disengaged. The swing arm 3 is operated to rotate synchronously around the main shaft hole 17 of the straight knife blade, thereby realizing the opening or closing of the straight knife.
[0015] Preferably, the threaded spacer sleeve 41, the threaded stop pin 18, and the spindle nut 2 are all provided with threaded holes at both ends to connect with the screw 22 and the spindle screw 20.
[0016] The specific usage and function of this utility model are described in detail below: When this utility model needs to be used, firstly... Figure 4 The swing arm rotates as follows: Figures 3 to 1As shown, at this time, under the action of the spring 40, the button 39 causes the protruding edge 24 to snap onto the second locking groove 5 to fix the swing arm 3, effectively preventing the swing arm 3 from loosening during use. When this utility model is not needed, firstly... Figure 1 In the current state, press button 39 to separate the protruding edge 24 from the second locking groove 5, then rotate the swing arm 3 to... Figure 4 In this state, the spring 40 supports the lower protruding edge 24, which then latches onto the first locking groove 4 to lock the swing arm 3. This operation is repeated for subsequent uses. This utility model is simple to operate and can be used by both beginners and experienced users, achieving the effect of instantaneous opening and closing of the straight knife.
