[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-9 This utility model provides a multi-functional scissor with replaceable blades and base, including an upper handle 1 and a lower handle 2. Both the upper handle 1 and the lower handle 2 are provided with pin holes 3, and the same threaded pin 4 is inserted into the two pin holes 3. A return spring 5 is fixedly connected between the upper handle 1 and the lower handle 2, and a cutting blade 6 is installed between the upper handle 1 and the lower handle 2.
[0030] The shearing cutter 6 includes a blade 7 movably sleeved outside a threaded pin 4. The blade 7 has a mounting groove 8, through which the threaded pin 4 passes. A limiting pin 9 is fixedly connected to the lower handle 2, passing through the blade 7 via the mounting groove 8. A base 10 is mounted on the upper handle 1, and the base 10 is fixedly connected to the upper handle 1 by a locking bolt 11. A graduated shearing table 12 is fixedly connected to the upper side wall of the base 10, and the graduated shearing table 12 has a shearing groove 13 corresponding to the blade 7. A mounting hole 14 is provided on the vertical side wall of the base 10. A slide rail 15 is fixedly connected in the mounting hole 14. A sliding block 16 is movably sleeved on the slide rail 15. Two angle adjustment discs 17 are fixedly connected to the upper side wall of the sliding block 16. Both the lower side wall of the base 10 and the lower side wall of the sliding block 16 are provided with threaded holes 18 that communicate with the mounting hole 14. The same wing bolt 19 is threaded into the two threaded holes 18. A positioning element 20 is movably sleeved on the outside of the wing bolt 19. Multiple angle scale grooves 21 are provided on the upper side of the angle adjustment disc 17.
[0031] In the first embodiment, when cutting grooves of different lengths, the wing bolt 19 is tightened. Through the threaded engagement between the wing bolt 19 and the threaded hole 18 on the sliding block 16, the wing bolt 19 is disengaged from the sliding block 16, thereby releasing the limiting fixation of the sliding block 16 by the wing bolt 19. This pushes the sliding block 16, allowing it to move on the slide rail 15, thus adjusting the position of the angle adjustment disc 17. The position of the angle adjustment disc 17 can be flexibly adjusted according to the actual length of the groove, thereby achieving precise cutting of grooves of different sizes. The set scale... The shearing table 12 can accurately position the length of the wire groove, which can improve the shearing accuracy. By turning the wing bolt 19, the limiting fixation of the wing bolt 19 on the positioning member 20 can be released. By rotating the positioning member 20, the positioning member 20 can rotate around the wing bolt 19 as the axis, thereby adjusting the angle between the positioning member 20 and the angle adjustment plate 17. The positioning angle of the positioning member 20 can be adjusted according to the actual shearing needs, which effectively improves the flexibility of the shears. Furthermore, by loosening the threaded pin 4, the limiting fixation of the threaded pin 4 on the blade 7 can be released, which facilitates the replacement of the blade 7.
[0032] The shearing cutter 6 also includes a second blade 22 installed between the threaded pin 4 and the lower handle 2. The upper handle 1 is fixedly connected to a mounting base 24 by a second locking bolt 23. A shearing seat 25 is fixedly connected to the mounting base 24 by screws. A semi-circular positioning groove 26 is provided on the upper side of the shearing seat 25.
[0033] In the second embodiment, the first and second embodiments are configured such that the locking bolts 11 and 23 allow for quick disassembly and installation of the shearing blade 6, enabling rapid replacement of different chassis. This allows for flexible replacement of different models of shearing blades 6 according to actual usage needs, making the shears adaptable to different usage environments. In the first embodiment, the shearing blade 6 can cut different wire grooves, while in the second embodiment, the shearing seat 25, when installed in the forward direction, can cut pipes, and when installed in the reverse direction, it can cut branches, effectively improving the versatility of the shears.
[0034] The upper handle 1 and the lower handle 2 are evenly provided with multiple anti-slip grooves 27, which can improve the anti-slip performance of the scissors when in use.
[0035] The sliding block 16 has a sliding hole 28, and the slide rail 15 passes through the sliding block 16 through the sliding hole 28. The hole wall of the sliding hole 28 and the lower side wall of the slide rail 15 are both fixedly connected with multiple locking teeth 29. The locking teeth 29 can improve the stability of the sliding block 16 when locked and its cooperation with the slide rail 15, thereby improving the stability of the shearing tool 6 when in use.
[0036] The positioning component 20 includes a U-shaped plate 30, with U-shaped positioning blocks 31 fixedly connected to both ends of the U-shaped plate 30. The U-shaped positioning blocks 31 are movably sleeved on the angle adjustment disk 17. The two U-shaped positioning blocks 31 can cooperate with the two angle adjustment disks 17 to improve the positioning accuracy.
[0037] The U-shaped positioning block 31 has a first positioning hole 32, and the angle adjustment disk 17 has a plurality of second positioning holes 33 corresponding to the first positioning hole 32. The plurality of second positioning holes 33 are arranged in an arc shape. By cooperating with the first positioning hole 32 and the second positioning hole 33, the accuracy of the adjustment of the positioning component 20 and the angle adjustment disk 17 can be improved.
[0038] The upper handle 1 is fixedly connected with a limiting pin 34, and the lower handle 2 is provided with a limiting groove 35 corresponding to the limiting pin 34. The limiting pin 34 and the limiting groove 35 cooperate with each other to limit and support the lower handle 2, thereby improving the stability of the scissors closing.
[0039] The lower grip 2 includes an operating handle 36, and a U-shaped clamp 37 is fixedly connected to the upper end of the operating handle 36. The blade 7 is installed in the U-shaped clamp 37. The U-shaped clamp 37 can limit the blade 7 and improve the stability of the blade 7 installation.
[0040] Working principle: When cutting troughs of different lengths, the wing bolt 19 is tightened. Through the threaded engagement between the wing bolt 19 and the threaded hole 18 on the sliding block 16, the wing bolt 19 is disengaged from the sliding block 16, thus releasing the limiting fixation of the sliding block 16 by the wing bolt 19. This pushes the sliding block 16, allowing it to move on the slide rail 15, thereby adjusting the position of the angle adjustment disc 17. The position of the angle adjustment disc 17 can be flexibly adjusted according to the actual length of the trough, enabling precise cutting of troughs of different sizes. The set scale cutting... The cutting table 12 can accurately position the length of the wire groove, which can improve the cutting accuracy. By turning the wing bolt 19, the limiting fixation of the wing bolt 19 on the positioning member 20 can be released. By rotating the positioning member 20, the positioning member 20 can be rotated around the wing bolt 19 as the axis, thereby adjusting the angle between the positioning member 20 and the angle adjustment plate 17. The positioning angle of the positioning member 20 can be adjusted according to the actual cutting needs, which effectively improves the flexibility of the scissors. Furthermore, by loosening the threaded pin 4, the limiting fixation of the threaded pin 4 on the blade 7 can be released, which makes it easy to replace the blade 7.
[0041] Through the first and second embodiments, the locking bolts 11 and 23 allow for quick disassembly and installation of the shearing blade 6, and the rapid replacement of different chassis. This enables flexible replacement of different models of shearing blades 6 according to actual usage needs, allowing the shears to adapt to different usage environments. In the first embodiment, the shearing blade 6 can cut different wire grooves, while in the second embodiment, the shearing seat 25, when installed in the forward direction, can cut pipes, and when installed in the reverse direction, it can cut branches, effectively improving the versatility of the shears.
