Technical Field
[0001] The utility model relates to the technical field of wrenches, in particular to a combined wrench. Background Art
[0002] A wrench is a tool used to remove nuts or bolts. There are different models that can correspond to different bolts, etc., and according to different usage methods, wrenches are divided into adjustable wrenches, fixed wrenches, hexagonal wrenches, cylinder wrenches and universal wrenches, which can correspond to different usage environments and usage situations. These wrenches are made of metal, have extremely high hardness and corrosion resistance, are heavy, and the outer surface is generally chrome-plated, so wrenches are generally bright silver, which is more eye-catching, and when oil stains adhere to it, it is easy to clean the stains. The use environment of the wrench is relatively harsh, and after long-term use, there will be a certain error in the accuracy.
[0003] In the auto repair industry, wrenches are indispensable tools. Various types of wrenches are required for the disassembly and installation of damaged parts. In addition, during the disassembly process, different types of wrenches are required to disassemble and assemble the workpieces. Ordinary wrenches can only disassemble one type of bolts or nuts. When different types of bolts appear, the wrenches need to be replaced, which is troublesome. Moreover, many wrenches left in the work area are often lost, causing inconvenience. Secondly, ordinary wrenches are used to disassemble ordinary hexagonal bolts and hexagonal nuts. When it is necessary to disassemble a flat-head or cross screw, a corresponding screwdriver needs to be specially used. It is time-consuming to take and put the wrench back and forth. Finally, the angle between the wrench and the grip rod cannot be changed. It is difficult to disassemble some bolts with special installation positions. Therefore, a combined wrench is proposed to address the above problems. Utility Model Content

[0026] Working process: The device is composed of multiple parts. The wrench 1 can remove and install three different types of bolts or nuts. A connecting rod 2 with a connecting function is fixed on one side of the wrench 1. A mounting groove 3 is provided inside the connecting rod 2. A conical hole 4 is provided on one side of the mounting groove 3. A spring 5 is installed in the conical hole 4. When the wrench 1 needs to be installed on the connecting head 10, the mounting groove 3 is aligned with the connecting head 10, and the wrench 1 is pressed hard. The connecting rod 2 enters the outside of the connecting head 10. A conical hole 4 is also provided inside the connecting rod 2. The spring 5 presses the round ball 6 inside it. When the connecting rod 2 enters the mounting groove 3, the ... After the straight rod 7 is in the right position, the ball 6 is pressed against the positioning groove 11 to fix the connecting rod 2 and the wrench 1, so as to prevent the wrench 1 from falling off during use. A straight shaft 8 is fixed in the notch at one end of the straight rod 7, and the rotating block 9 rotates on the outside of the straight shaft 8. When the position of the bolt to be removed is special, the angle between the wrench 1 and the straight rod 7 can be changed. A handle 14 is provided at the other end of the straight rod 7, and a receiving groove 15 is provided in the handle 14, in which two screwdrivers 16 can be stored at the same time, which can meet the needs of removing some bolts. A plug cover 18 can also be installed at the tail of the receiving groove 15, and the plug cover 18 and the handle 14 are threadedly connected. After the screwdriver 16 is stored in the receiving groove 15, the plug cover 18 can be tightened into the handle 14. The rubber block 19 on one side of the plug cover 18 will directly contact the hexagonal prism 17 of the screwdriver 16, pressing the screwdriver 16 tightly into the receiving groove 15 to prevent the screwdriver 16 from shaking between the receiving groove 15 when not in use. The baffle 20 is attached to the tail of the handle 14. When the screwdriver 16 needs to be used to remove the bolt, the plug cover 18 is removed from the handle 14, and then the screwdriver 16 to be used is taken out of the receiving groove 15, and the hexagonal prism 17 at one end of the screwdriver 16 is inserted into the fixing hole on the connector 10. In the groove 12, the cross-section of the fixing groove 12 is a regular hexagon, which wraps the hexagonal prism 17 therein. A magnet 13 is also provided on the innermost side of the fixing groove 12. After the hexagonal prism 17 completely enters the fixing groove 12, the magnet 13 and the hexagonal prism 17 are magnetically connected, which can prevent the screwdriver 16 from accidentally falling during use. When the screwdriver 16 is not in use, the screwdriver 16 can be stored in the receiving groove 15 to prevent the screwdriver 16 from being lost. When it is needed, there is no need to look for the screwdriver 16, and it can be directly taken out of the receiving groove 15 for use, which reduces the difficulty and time of finding tools and improves work efficiency.
