Description

Technical Field

[0001] This utility model relates to a disassembly and assembly tool that is convenient for use in confined spaces, and more particularly to a tool with an overall thin design that can be inserted into confined spaces to disassemble and assemble screws, nuts and parts electrically or manually. Background Technology

[0002] Currently, tools used for disassembling and assembling screws, nuts, and parts generally include manual and electric screwdrivers, adjustable wrenches, fixed wrenches, and socket wrenches. These tools mostly have specific dimensions. Manual or electric screwdrivers, adjustable wrenches, and fixed wrenches are primarily used for disassembling screws and nuts at straight angles. While some socket wrenches have a bendable design, allowing them to be used for disassembling at straight or curved angles, their standard sizes mean that these traditional tools are difficult or even impossible to use when disassembling screws and nuts in confined spaces. Using them would be time-consuming and labor-intensive. For example, consider the tailgate panel 32 of a typical car. Figure 10 As shown, in most cars, the rear door panel 32 is connected to the body 31 by a set of hinges 33 on both sides of the top edge of the rear door panel 32. The space where the hinges 33 are located in most cars is quite small, so that the rear door panel 32 does not have a large gap when it is opened, which affects the appearance. However, due to the small space, when it is necessary to remove the screws 331 or nuts of the hinges 33 of the rear door panel 32, there is no suitable tool. Therefore, it is often necessary to use traditional tools to slowly remove the screws 331 or nuts of the hinges 33. In addition, extra manpower is required to lift and support the relatively heavy rear door panel 32 to prevent it from falling or tilting and affecting the disassembly work. Therefore, it is quite time-consuming and labor-intensive, which increases the maintenance cost. Utility Model Content

[0003] The main purpose of this utility model is to provide a disassembly and assembly tool that is convenient for use in confined spaces. Through the thin design of the main body, together with the thin design of the main drive wheel and tool parts, it can reach into confined spaces and improve the convenience of disassembling and assembling screws, nuts and parts in confined spaces.

[0004] A secondary objective of this invention is to provide a disassembly and assembly tool that is convenient for use in confined spaces. By using an electric or pneumatic tool to attach to the polygonal end of the drive rod and drive the drive rod to rotate, the thread at the front end of the drive rod drives the main drive wheel to rotate, and the main drive wheel simultaneously drives the tool to rotate, thereby improving disassembly and assembly efficiency and saving time.

The thread at the front end of the drive rod engages with the tooth grooves on the outer edge of the main drive wheel. A bottom cover is assembled at the bottom of the receiving space at the front end of the main body. The assembly also includes a tool that can be disassembled and replaced. The tool has a polygonal base and at least one tool end of different shapes and specifications on the polygonal base. The tool is inserted into the inner edge of the main drive wheel. Each corner formed by the polygonal base of each tool will engage with the tooth grooves on the inner edge of the main drive wheel. An electric tool or pneumatic tool is sleeved on the polygonal end of the drive rod and drives the drive rod to rotate. This enables the thread at the front end of the drive rod to drive the main drive wheel to rotate, and the main drive wheel to synchronously drive the tool to rotate.

[0007] The disassembly and assembly tool, which is advantageous for use in confined spaces, wherein the tool end of the tool is of the form of a polygonal inner hole, a multi-tooth type, a polygonal column type, a straight type, or a cross type.

[0008] The disassembly and assembly tool, which is advantageous for use in confined spaces, wherein the tool end of the tool is a multi-tooth type with a concave hole at the top.

[0009] The disassembly and assembly tool is designed for use in confined spaces, wherein the bottom cover is secured with screws to seal the accommodating space of the main body.

[0010] The disassembly and assembly tool, which is convenient for use in confined spaces, includes: an assembly part for assembling a bearing is provided at the center of the top of the bottom cover; a cam is provided at the bottom of the main drive wheel; and the cam is fitted into the bearing inner hole provided at the center of the top of the bottom cover, so that the main drive wheel can rotate freely around the bearing as the axis.

[0011] The disassembly and assembly tool, which is advantageous for use in confined spaces, has a magnet at the bottom of the main drive wheel, which attracts the inserted tool parts without them coming loose.

[0012] The main body of this utility model is designed to be thin, making it suitable for disassembling and assembling screws, nuts, and parts in confined spaces. A tool of the required size is inserted into the inner edge of the main drive wheel. Each corner of the polygonal base of the tool will fit into the toothed grooves provided on the inner edge of the main drive wheel. When an electric tool or pneumatic tool is attached to the polygonal end of the drive rod and drives the drive rod to rotate, the thread at the front end of the drive rod drives the main drive wheel to rotate, and the main drive wheel simultaneously drives the tool to rotate, so as to perform the disassembly and assembly of screws, nuts, and parts in confined spaces.
