Problems solved by technology

For a disassembly and assembly object, the disassembly and assembly spaces of different disassembly and assembly parts are often of different sizes and entry angles. Although the ratchet wrench has the above advantages, the length, shape and angle of the operating handle are fixed. When the above problems are encountered, the advantages of its ease of use cannot be brought into play, which brings certain limitations to its use.

Abstract

The invention provides a multifunctional ratchet wrench, which comprises a switching handle and one or more tools. Each of the tools is matched with the switching handle, and is provided with a wrench. The switching handle comprises a handle and a tool joint, which are hinged. Each tool with the wrench comprises a connecting handle and a ratchet wrench mechanism arranged at one end of the connecting handle. The tool joint can be detachably connected with different specifications of tools with the wrenches, and can rotate relative to the handle, and an included angle between the handle and the tool can be changed by rotation according to different operating spaces and the habits of operators to change the overall shape and operating angle of the ratchet wrench, so that the multifunctional ratchet wrench is convenient to operate and more labor-saving.

Description

technical field [0001] The invention relates to a wrench tool, in particular to a multifunctional ratchet wrench. Background technique [0002] The ratchet wrench has become a wrench tool widely used in the world. There is a ratchet device on the head, which can control the wrench to only turn left or right through the paddle placed on the outside. Because of this ratchet device, the operator It is widely used because there is no need to repeatedly pull out and put in. For a disassembly and assembly object, the disassembly and assembly spaces of different disassembly and assembly parts are often of different sizes and entry angles. Although the ratchet wrench has the above advantages, the length, shape and angle of the operating handle are fixed. When the above-mentioned problem is reached, the advantage of its ease of use cannot be brought into play, which brings certain limitations to its use. Contents of the invention [0003] The technical problem to be solved by...
