[0022] 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.

[0023] Referring to Figures 1-3, one embodiment of this utility model provides a multi-functional auto repair wrench, including a rod body 1. A groove 5 is provided at the middle end of the rod body 1, and the diameter of the top end of the groove 5 is much larger than the diameter of the bottom end of the groove 5. A movable rod 10 is slidably connected to the right end of the rod body 1. By pulling the movable rod 10 out of the rod body 1, the lever arm for tightening bolts can be lengthened, making it easier for workers to tighten bolts. The movable rod 10 is connected to the rod body 1 through an adjustment component, which can adjust the length of the movable rod 10 and limit its movement. A socket wrench head 8 is fixedly connected to the right end of the movable rod 10, and a pry block 9 is fixedly connected to the right end of the socket wrench head 8. The pry block 9 can pry up some rivets or parts. An adjustable wrench head 2 is fixedly connected to the left end of the rod body 1, and a screwdriver head 4 is provided at the left end of the adjustable wrench head 2. A placement groove 7 is provided at the top end of the rod body 1 and the left end of the adjustable wrench head 2. The placement groove 7 is used to place the screwdriver head 4, increasing the overall practicality of the wrench.

[0024] Referring to Figures 2-4, the adjusting assembly includes a movable groove at the top of the movable rod 10. A limiting block 6 is installed in the movable groove, allowing it to move within the groove. A spring 11 is installed at the bottom of the limiting block 6, with one end connected to the limiting block 6 and the other end connected to the movable rod 10. By using the spring 11, the limiting block 6 can be pushed out, thereby pushing it into the groove 5 and fixing the position of the movable rod 10. A rotating block 3 is installed at the right end of the adjusting wrench head 2. Rotating the rotating block 3 allows the movable block to move, thus clamping bolts of different sizes. A movable block is installed at the left end of the adjusting wrench head 2. There are two grooves 5, and the diameter of the bottom of each groove 5 matches the diameter of the limiting block 6. The grooves 5 limit the limiting block 6, preventing the movable rod 10 from being pulled out. There are nine placement slots 7 located at the top of the rod 1, and the width of each slot 7 is adapted to the width of the screwdriver head 4. These slots are used to hold screwdriver heads 4 of different sizes. Magnets are installed on the inner walls of each slot 7 to hold the screwdriver head 4, ensuring its stability within the slot. The pry bar 9 is wedge-shaped and tilted to the right.

[0025] Working principle: By rotating the rotating block 3, the position of the adjusting wrench head 2 can be adjusted to clamp the bolt. Alternatively, the bolt can be fitted with the socket wrench head 8. During rotation, by pressing the limiting block 6 downward, the spring 11 is compressed, allowing the movable rod 10 to be pulled out from the rod body 1. When the limiting block 6 moves into another groove 5, the spring 11 returns to its original position, pushing the limiting block 6 out and thus limiting the movable rod 10. This ensures the stability of the movable rod 10 and prevents it from retracting or extending due to its own weight, achieving the effect of extending the lever arm for easier operation. The system reduces the difficulty for workers to tighten bolts. When a screwdriver is needed, the screwdriver head 4 is taken out from the slot 7 at the top of the rod 1 and then inserted into the slot 7 at the left end of the adjusting wrench head 2. The screwdriver head 4 is held in place by a magnet in the slot 7 to ensure its stability. Rivets or parts can be pried up by the pry bar 9. By setting different types of tools on the rod 1, the overall portability and practicality of the wrench are greatly improved, thereby increasing the efficiency of workers and reducing the frequency of tool changes during operation.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
