[0025] With reference to Figure 1-2 , the threaded end of the fixing screw 3 is movably arranged in the corresponding fixing hole 11, and the screw rod end of the fixing screw 3 penetrates through the fixing hole 11 of the threaded denture framework 1, and the nut of the fixing screw 3 is capable of abutting against the fixing hole 11 of the fixing screw 3 to be connected with the internal thread of the oral implant hole through the screw rod end of the fixing screw 3.

[0026] With reference to Figure 1-3 , a limiting groove 31 is arranged between the threaded end and the middle part of the screw rod end of the fixing screw 3, and a movable seat 32 is slidably arranged in the threaded end of the fixing screw 3, and the movable seat 32 is slidably connected in the corresponding limiting groove 31, and a square rod 33 extending to the inside of the screw rod end of the fixing screw 3 is fixedly arranged at the center of one side of the movable seat 32, and the square rod 33 is movably arranged in the corresponding limiting groove 31, and the fixing screw 3 can be connected and limited to the square rod 33 through the limiting groove 31, so that the square rod 33 can only move up and down, and due to the limitation of the square rod 33, the movable seat 32 can also move up and down in the limiting groove 31, and after the rotation of the movable seat 32, the fixing screw 3 will also be rotated by the limitation of the square rod 33.

[0027] With reference to Figure 1-3 , a tension member 36 for pulling the movable seat 32 to the screw rod end of the fixing screw 3 is fixedly arranged between the limiting groove 31 of the fixing screw 3 and one side of the movable seat 32, and the tension member 36 can be a tension spring or other objects with tension effect, and the tension member 36 can be connected between the movable seat 32 and the fixing screw 3, so that the movable seat 32 will not be separated from the fixing screw 3, and under the tension of the tension member 36, the movable seat 32 will be pulled to the screw rod end of the fixing screw 3.

[0028] With reference to Figure 2-3 , a loosening prevention mechanism is arranged in the screw rod end of the fixing screw 3, and the loosening prevention mechanism comprises a fastening rod 4 slidably arranged at one side of the screw rod end of the fixing screw 3, and a guide slope 41 arranged between the fastening rod 4 and one end of the square rod 33 for guiding the fastening rod 4 to be pressed out of the screw rod end of the fixing screw 3 and inserted into the internal thread of the implant hole after the movable seat 32 moves to the screw rod end of the fixing screw 3.

[0029] Through the tension of the tension member 36, the movable seat 32 can be pulled to the screw rod end of the fixing screw 3, so that the square rod 33 can be pushed out of the screw rod end of the fixing screw 3 through the guide of the guide slope 41 after moving with the movable seat 32, one end of the pushed-out fastening rod 4 is inserted into the internal thread of the oral implant hole, and the other end is abutted against the side wall of the square rod 33 so that the fastening rod 4 cannot move back, at this time, the pushed-out fastening rod 4 is clamped in the internal thread of the implant hole and cannot rotate, so as to tighten and prevent loosening of the fixing screw 3.

[0030] With reference Figure 2-3 The fixed screw 3 is provided with a spring 42 in the screw rod end for pushing the fastening rod 4 back into the screw rod end of the fixed screw 3 after the movable seat 32 moves away from the screw rod end of the fixed screw 3. A sliding groove 43 is formed in the screw rod end of the fixed screw 3. The spring 42 is fixedly connected in the sliding groove 43 of the fixed screw 3. A connecting ring 44 is fixedly connected between one end of the spring 42 and the outer wall of the fastening rod 4. A cross slot 34 is formed in the middle of one side of the movable seat 32 for inserting the magnetic screwdriver. A magnetic block 35 is fixedly arranged in the movable seat 32 for magnetic attraction connection with the magnetic screwdriver. The sliding groove 43 can support and limit the connecting ring 44. The connecting ring 44 can connect the spring 42 and the fastening rod 4.

[0031] When the fixed screw 3 is disassembled and assembled, the staff can insert the magnetic screwdriver into the cross slot 34 and magnetically attract and fix the movable seat 32 through the magnetic attraction of the magnetic block 35. Then the movable seat 32 is moved away from the screw rod end of the fixed screw 3. At this time, the square rod 33 moved with the movable seat 32 moves reversely, so that one end of the fastening rod 4 is separated from the side wall of the square rod 33, and the guiding inclined surface 41 between the fastening rod 4 and the square rod 33 is re-attached. At this time, the fastening rod 4 can be retracted into the screw rod end of the fixed screw 3 under the elastic force of the spring 42, so as not to hinder the rotation of the fixed screw 3 during disassembly and assembly.

[0032] The implementation principle of the bolt channel type rod card in the embodiment of the application is as follows:

[0033] In use, the extension rod 21 and the adhering sheet 22 can be adhered in the cavity. The extension rod 21 and the adhering sheet 22 in the rod card 2 can extend the two ends of the bolt channel type denture framework 1, so as to improve the support strength of the ends of the bolt channel type denture framework 1, increase the contact area of the bolt channel type denture framework 1 in the oral cavity, and improve the stability after wearing the bolt channel type denture framework 1. The nut of the fixed screw 3 can be abutted in the fixing hole 11 of the fixed screw 3 to be connected with the thread in the implant hole through the screw rod end of the fixed screw 3.

[0034] When the fixed screw 3 is disassembled and assembled, the staff can insert the magnetic screwdriver into the cross slot 34 and magnetically attract and fix the movable seat 32 through the magnetic attraction of the magnetic block 35. Then the movable seat 32 is moved away from the screw rod end of the fixed screw 3. At this time, the square rod 33 moved with the movable seat 32 moves reversely, so that one end of the fastening rod 4 is separated from the side wall of the square rod 33, and the guiding inclined surface 41 between the fastening rod 4 and the square rod 33 is re-attached. At this time, the fastening rod 4 can be retracted into the screw rod end of the fixed screw 3 under the elastic force of the spring 42, so as not to hinder the rotation of the fixed screw 3 during disassembly and assembly.

[0035] After installation, the magnetic screwdriver is pulled away from the side of the fixing screw 3, and through the pulling force of the pulling piece 36, the movable seat 32 can be pulled towards the screw rod end of the fixing screw 3, so that the square rod 33 moves with the movable seat 32 and can be guided by the guide inclined surface 41 to push the fastening rod 4 out of the threaded end of the fixing screw 3. One end of the pushed-out fastening rod 4 will be inserted into the internal thread of the implant hole in the oral cavity, and the other end will abut against the side wall of the square rod 33, so that the fastening rod 4 cannot be moved back. At this time, the pushed-out fastening rod 4 will be clamped in the internal thread of the implant hole and cannot rotate, thereby tightening and preventing loosening of the fixing screw 3.

[0036] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
