[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 7 As shown, the utility model discloses a tool for facilitating the disassembly and assembly of a slotted nut 1, comprising a slotted nut 1 and a disassembly knife 2, wherein the disassembly knife 2 comprises a blade section 21 at the front side, wherein the blade section 21 comprises a positioning groove 211 for inserting the slotted nut 1, wherein the blade section 21 is cylindrical and extends leftward and rightward in the length direction and is located at the upper side of the positioning groove 211 and is openly arranged, wherein the blade section 21 is located at the left and right sides of the positioning groove 211 and is respectively provided with a left positioning plug block 212 and a right positioning plug block 213 protruding therefrom, and the slotted nut 1 is provided with a disassembly and assembly groove 11 for inserting the left positioning plug block 212 and the right positioning plug block 213, and by After the left positioning block 212 and the right positioning block 213 are inserted into the disassembly and assembly groove 11, the disassembly knife 2 can be rotated to transmit the torque to the slotted nut 1 through the left positioning block 212 and the right positioning block 213. The setting of the left positioning block 212 and the right positioning block 213 enhances stability. The left positioning block and the right positioning block 213 ensure that the blade segment 21 fits tightly with the disassembly and assembly groove 11 to prevent the blade segment 21 from shifting during rotation, keep the blade segment 21 aligned, improve the operating efficiency and accuracy, and thus realize the rotation of the slotted nut 1: 1. Since the blade segment 21 is located on the left and right sides of the positioning groove 211, the left positioning blocks are respectively protruded 2. Compared with the traditional flat head end, which needs to be completely inserted into the disassembly and assembly groove 11 and causes indentations or scratches to the disassembly and assembly groove 11, the design of the left positioning block 212 and the right positioning block 213 reduces damage to the slotted nut 1 and protects the surface integrity of the slotted nut 1; 2. Compared with the traditional flat head end setting, the left positioning block 212 and the right positioning block 213 can better match more different types of slotted nuts 1, even non-standard size or shape screws, increase compatibility, and have stronger versatility; 3. Reduce damage to the blade section 21, the design of the left positioning block 212 and the right positioning block 213 reduces wear The concentrated stress points of the blade segment 21 are dispersed, which prolongs the service life, maintains the tool life and reduces frequent replacement; 4. The left positioning block 212 and the right positioning block 213 are designed to be easier to align than the traditional flat head end, so that the blade segment 21 can quickly locate the slotted nut 1, which reduces the difficulty of misoperation and improves efficiency; 5. Since the blade segment 21 is located on the upper side of the positioning groove 211 and is open, at this time, due to the opening on the upper side, the slotted nut 1 can squeeze the positioning groove 211 more smoothly and then fall into the positioning groove 211, so that the left positioning block 212 and the right positioning block 213 are inserted into the disassembly and assembly groove 11.

[0026] Among them, the blade segment 21 also includes a left observation block 214 and a right observation block 215 extending forward and backward in the length direction. The left observation block 214 and the right observation block 215 are both located in the circumference of the blade segment 21 and are respectively located at the same height as the left positioning block 212 and the right positioning block 213. Since the left observation block 214 and the right observation block 215 are respectively located at the same height as the left positioning block 212 and the right positioning block 213, after the left positioning block 212 and the right positioning block 213 are located in the disassembly groove 11 of the slotted nut 1, the positions of the left positioning block 212 and the right positioning block 213 can be connected by observing the left observation block 214 and the right observation block 215, that is, the operator's intuitive field of vision is improved, the accuracy of the left positioning block 212 and the right positioning block 213 in the circumference of the blade segment 21 is ensured, misoperation is reduced, and operational safety and accuracy are improved.

[0027] Among them, the disassembly knife 2 also includes a connecting section 22 located at the rear side of the blade segment 21, and the connecting section 22 includes a limiting portion 221 on the front side. The limiting portion 221 is provided with a plurality of limiting plugs 2211 located in the circumference of the blade segment 21, and the blade segment 21 is inserted into the connecting section 22, and the left observation block 214 and the right observation block 215 are respectively located between adjacent limiting plugs 2211. Since there are a plurality of limiting plugs 2211 on the limiting portion 221, and the left observation block 214 and the right observation block 215 are respectively located between adjacent limiting plugs 2211, after the blade segment 21 is inserted into the connecting section 22 during the assembly process, due to the existence of the left observation block 214 and the right observation block 215, the blade segment 21 cannot rotate compared to the connecting section 22, so that the blade segment 21 can be stably located in the connecting section 22, which provides convenience for the installation of the connecting section 22 and the blade segment 21.

[0028] Preferably, the connecting section 22 includes a contact portion 222 located on the rear side of the limiting portion 221, and the contact portion 222 is circumferentially protruding with a plurality of rear contact ridges 2221 extending forward and backward. The presence of each rear contact ridge 2221 can increase the circumferential roughness of the contact portion 222 and thereby increase the friction of the contact portion 222, so that the hand can hold the contact portion 222 of the connecting section 22 more firmly during operation, thereby preventing slipping and falling that may cause injury to the hand or damage to surrounding objects, thereby improving control.

[0029] Among them, it also includes a protective sleeve 3, and the connecting section 22 also includes a mounting portion 223 located between the limiting portion 221 and the contact portion 222. The mounting portion 223 is threadedly connected to the protective sleeve 3, and the outward projection of the limiting portion 221 falls inside the protective sleeve 3. The protective sleeve 3 is circumferentially provided with a plurality of front contact ridges 31. 1. Since the outward projection of the limiting portion 221 falls inside the protective sleeve 3, the limiting blocks 2211 of the limiting portion 221 after installation can be shielded by the protective sleeve 3, so that without the action of external force, 1. The user will not touch the limiting plug blocks 2211 and the left observation block 214 and the right observation block 215, so that the blade section 21 can be stably inserted in the connecting section 22 without relative rotation; 2. Since the protective cover 3 is threadedly connected to the mounting portion 223, the protective cover 3 is detachable and can be stably positioned around the limiting portion 221 during installation without being separated therefrom; 3. Due to the setting of the front contact ridge 31, the circumferential friction of the protective cover 3 is increased, and then cooperates with the rear contact ridge 2221 to increase the overall anti-slip area of ​​the connecting section 22.

[0030] The disassembly knife 2 further includes a gripping section 23 located at the rear side of the connecting section 22, the gripping section 23 is inserted at the rear side of the blade section 21, and the blade section 21 is provided with a plurality of connecting blocks 216 protruding in the circumferential direction, and the front side end face of each connecting block 216 abuts against the rear end face of the connecting section 22, and the gripping section 23 is provided with a connecting slot 231 corresponding to each connecting block 216, 1. Since the front side end face of each connecting block 216 abuts against the rear end face of the connecting section 22, the protective cover 3 and each connecting block 216 can contact the connecting section 22. 1. The front and rear limits are provided at the circumferential position of the blade segment 21, thereby facilitating the installation of the connecting segment 22 on the blade segment 21; 2. Since the holding segment 23 is provided with connecting slots 231 corresponding to each connecting plug block 216, when the holding segment 23 is installed, the positions of the holding segment 23 and the blade segment 21 can be determined by inserting each connecting plug block 216 on the blade segment 21 into each connecting slot 231 of the holding segment 23, so that the holding segment 23 cannot rotate compared with the blade segment 21, thereby facilitating the assembly of the holding segment 23 and the blade segment 21.

[0031] Preferably, a rear magnet 217 is provided on the rear side of the blade segment 21, and a front magnet 232 that is attracted to the rear magnet 217 is provided in the holding segment 23. Since the front magnet 232 is attracted to the rear magnet 217, after the holding segment 23 is installed so that each connecting plug 216 can enter the corresponding connecting slot 231, the presence of the front magnet 232 and the rear magnet 217 enables the holding segment 23 to be stably located in the circumferential direction of the rear side of the blade segment 21.

[0032] By applying force to separate each connecting plug block 216 from the corresponding connecting slot 231, the front magnet 232 can be separated from the rear magnet 217, that is, the grip section 23 can be removed from the blade section 21, thereby facilitating the disassembly of the various parts of the knife 2.

[0033] In addition, it is worth noting that since the gripping section 23 and the blade section 21 cannot rotate relative to each other, the blade section 21 cannot rotate after the disassembly knife 2 is assembled, which indirectly makes the protective cover 3 unable to rotate, thereby making the protective cover 3 more stably mounted on the connecting section 22. During assembly, the connecting section 22 needs to be first installed on the blade section 21 and then the blade section 21 is rotated to achieve the threaded fit of the protective cover 3 and the blade section 21, and then the gripping section 23 is installed to achieve the assembly of the disassembly knife 2. Similarly, the gripping section 23 needs to be separated from the blade section 21 before the blade section 21 can be rotated to achieve the removal of the protective cover 3 from the blade section 21.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
