Description

Technical Field

[0001] This utility model belongs to the field of hand tools and relates to a wrench tool for assembling and disassembling nuts in confined spaces. Background Technology

[0002] When assembling or repairing compact electronic products, it is often necessary to install and remove nuts in confined spaces. Conventional wrenches, due to their size and shape limitations, often cannot easily enter such spaces or accurately position the nuts for effective installation and removal. Operators need to apply more force to tighten or loosen the nuts, and it is impossible to ensure that the nuts are securely locked. In addition, prolonged use can easily cause hand fatigue for the operator. Summary of the Invention

[0003] The purpose of this utility model is to solve the problem that conventional wrenches are difficult to use in confined spaces or cannot accurately position nuts when assembling or repairing compact electronic products, resulting in inconvenient operation and difficulty in guaranteeing the tightening effect; at the same time, it solves the problem that prolonged use by operators can easily cause hand fatigue, and provides a nut removal and installation wrench for confined spaces.

[0004] The present invention provides a nut removal and installation wrench for use in confined spaces, comprising a conversion bit 1, a connecting rod 2, a rivet 3, and a handle 4; the conversion bit 1 and the connecting rod 2 are fixed together by a four-way connector, and the connecting rod 2 and the handle 4 are fixed together by the rivet 3.

[0005] The conversion bit 1 has a square sleeve interface at the base and an open design at the head, allowing for the replacement of different sized conversion bits according to the size of the nut.

[0006] The square sleeve interface of the conversion bit 1 is equipped with anti-drop steel balls.

[0007] The connecting rod 2 is long and slender, with a connection hole at the head for connecting to the handle 4, and an opening at the bottom. The opening adopts a standard square interface and has a built-in anti-detachment slot.

[0008] The handle 4 is made of fabric-reinforced bakelite material, and the handle body has an anti-slip design.

[0009] The handle 4 has a connecting hole at its base for connecting to the connecting rod 2.

[0010] The technical advantages of this invention are as follows: This invention provides a nut removal and installation wrench for confined spaces. It allows easy access to narrow spaces, and the open design of the interchangeable bits ensures a precise fit between the wrench and the nut, allowing the operator to remove or install the nut without applying excessive force. Furthermore, it allows for the replacement of the corresponding sized interchangeable bits according to the nut size. This invention shortens the operation time for removing and installing nuts in confined spaces, ensures a secure nut tightening, and improves work efficiency and product quality. The material and anti-slip design of the handle improve comfort and grip stability, reducing hand fatigue after prolonged use. The ability to quickly change interchangeable bits according to nut size enhances the tool's convenience and practicality. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-8 As shown, a nut removal and installation wrench for use in confined spaces, used for the assembly and repair of compact electronic products, includes a conversion bit 1, a connecting rod 2, a rivet 3, and a handle 4; the conversion bit 1 and the connecting rod 2 are fixed together by a four-way connector, and the connecting rod 2 and the handle 4 are fixed together by the rivet 3.

[0023] The conversion bit 1 has a square sleeve interface at the base and an open design at the head, allowing for the replacement of different sized conversion bits according to the size of the nut.

[0024] The square sleeve of the conversion bit 1 is equipped with anti-slip steel balls, making the sleeve less prone to slippage.

[0025] The connecting rod 2 is long and slender, with a connection hole at the head for connecting to the handle 4, and an opening at the bottom. The opening adopts a standard square interface and has a built-in anti-detachment slot.

[0026] The handle 4 is made of fabric-reinforced bakelite material to reduce its weight. The handle body has an anti-slip design to reduce hand slippage.

[0027] The handle 4 has a connecting hole at its base for connecting to the connecting rod 2.

[0028] Example 1

[0029] A compact electronic product has multilayer printed circuit boards with narrow spacing placed in corresponding slots in the housing. By using a nut removal wrench, the narrow space can be easily accessed to tighten the nuts. This causes the locking devices on both sides of the printed circuit board to rub against the groove rails on which the printed circuit board is located, thus achieving a tightening effect.

[0030] Once the nut removal wrench is inserted into a confined space, the hand rotation operation is located outside the confined space, allowing for flexible operation without interference with the edge of the space. During rotation, the hand experiences uniform force without resistance.

[0031] This nut removal and installation wrench is lightweight and provides a firm grip. The handle has an anti-slip design to reduce hand fatigue.

[0032] A product contains nuts of various sizes that need to be tightened. This nut removal and installation wrench completes the tightening of all nuts by changing the corresponding size conversion bit.
