[0030] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: an anti-fracture ratchet wrench, comprising two wrench handles 1, the inner sides of the two wrench handles 1 are slidably connected with an insert block 2, the outer side of the insert block 2 is fixedly connected with a wrench head 3, the outer sides of the two wrench handles 1 are fixedly connected with a fixed block 1 4, the interior of the fixed block 1 4 is slidably connected with a paddle rod 5, one side of the outer side of the paddle rod 5 is sleeved with a spring 6, the other side of the outer side of the paddle rod 5 is fixedly connected with a square plate 7, the outer side of the fixed block 1 4 is fixedly connected with a fixed block 2 8, one side of the inner side of the fixed block 2 8 is slidably connected with a clamping block 9, the other side of the inner side of the fixed block 2 8 is fixedly connected with a limiting plate 10, and a connecting component is arranged between the two wrench handles 1.
[0031] Specifically, the wrench handle 1 serves to facilitate hand-held use, the insert block 2 serves to facilitate replacement of the wrench head 3, the fixed block 1 4 serves to protect internal parts, the paddle rod 5 serves to drive the square plate 7 to slide inside the fixed block 1 4 and compress the spring 6, the spring 6 serves to reset, the square plate 7 serves to drive the paddle rod 5 when sliding, the fixed block 2 8 serves to protect internal parts, the clamping block 9 serves to limit the paddle rod 5, and the limiting plate 10 serves to limit the clamping block 9.
[0032] Reference Figure 1 and Figure 2 The connecting assembly includes a connecting block 11, the outside of the connecting block 11 is arranged between the two wrench handles 1, and threaded rods 12 are fixedly connected to both sides of the outside of the connecting block 11. The outside of the wrench handle 1 is rotatably connected to the outside of the connecting block 11, and the inside of the wrench handle 1 is threadedly connected to the outside of the threaded rod 12.
[0033] Specifically, the connecting block 11 serves to fix the threaded rod 12 , and the threaded rod 12 serves to facilitate the movement of the wrench handle 1 , so that the wrench handle 1 can still be used normally in a narrow area.
[0034] Reference Figure 1 , Figure 3 and Figure 4 The paddle rod 5 passes through the wrench handle 1, the outside of the paddle rod 5 is plugged into the inside of the plug block 2, the outside of the square plate 7 is slidably connected to the inside of the fixed block 4, one end of the spring 6 is fixedly connected to the inside of the fixed block 4, the other end of the spring 6 is fixedly connected to the outside of the square plate 7, the outside of the fixed block 8 is fixedly connected to the outside of the wrench handle 1, and the limit plate 10 is in conflict with the square plate 7.
