Problems solved by technology
[0003] The purpose of the present invention is to provide a multifunctional detachable wrench, which solves the problem that when removing special nuts, ordinary wrenches and socket wrenches cannot be used, and the entire part of the special nut must be removed to have enough space to remove it. First, it is time-consuming and labor-intensive, and for precision components with high assembly size requirements, the design accuracy may not be maintained due to the overall disassembly, which improves the efficiency of special nut disassembly and assembly accuracy, and improves the yield of products

Embodiment Construction
[0017] The beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings, in order to help readers
[0018] Readers can better understand the essence of the present invention, but it cannot constitute any limitation to the implementation and protection scope of the present invention.
[0019] A multifunctional detachable wrench, which includes a wrench body 1, a fixing screw 2, a wrench arm 3, and a matching wrench head 4. The wrench body includes a central axis 13 and a handle 14 that are perpendicular to each other, and a handle that connects the lower end of the central axis and is perpendicular to the central axis. The connecting rod is provided with several second through holes 12 for fixing the arm, the connecting rod 15 is provided with the first through hole 11 for inserting the wrench arm, and several threaded connections are evenly distributed on the wrench arm. The threaded hole 31 of the fixing screw, th...

The invention relates to a multifunctional dismountable spanner. The multifunctional dismountable spanner comprises a spanner main body, a fastening screw, a spanner arm and a matched spanner head, the spanner main body comprises a central axis, a handle and a connecting rod; the central axis and the handle are mutually perpendicular, the connecting rod is connected with the lower end of the central axis and is perpendicular to the central axis; the multifunctional dismountable spanner solves the problems that the common spanner and the socket spanner cannot be used when a special nut is dismounted, the special nut can be dismounted only by dismounting the whole part of the special nut, then the time and the energy are consumed, and the design accuracy cannot be guaranteed for a precision part with high requirements on mounting dimensions possibly due to the integral dismounting; the dismounting efficiency and the assembly accuracy of the special nut are improved, and the product yield is increased.
Description
technical field [0001] The invention relates to a wrench, in particular to a multifunctional detachable wrench. Background technique [0002] With the continuous improvement of my country's comprehensive national strength, science and technology in various fields have entered the world's first-class level. Among them, in the field of aviation and manufacturing, there are some nuts with special shapes. Due to the limitation of shape and space, ordinary wrenches, socket wrench to remove it, refer to Figure 7 , the shape of the special nut is irregular hexagonal, and it is fixed in the cavity of the cylinder. If you want to remove the special nut, the ordinary wrench and socket wrench cannot be used. You must remove the whole part of the special nut to have enough It is time-consuming and labor-intensive to dismantle it, and for precision components with high assembly size requirements, the design accuracy may not be maintained due to the overall disassembly. Therefore, a multi...
