Description

A tool for loading and unloading nuts in confined spaces

technical field

The utility model relates to a nut loading and unloading tool in a limited space, which can be applied to the loading and unloading of connecting fastening nuts in a limited space with grooves in the process of equipment installation and maintenance in daily life and production.

Background technique

In daily life, the installation and disassembly of equipment and living utensils often require the use of bolts and nuts for connection and fastening. Cap handling tool for installation and removal work.

At present, the tool usually used for loading and unloading fastened connecting bolts and nuts is an adjustable wrench or a dead wrench. Usually, the loading and unloading operation space for connecting fastening bolts and nuts is mostly flat space or convex space, and the use of adjustable wrench or solid wrench can fully meet the disassembly requirements of connecting fastening bolts and nuts. However, during the installation and disassembly of equipment and living utensils, the nuts that need to be tightened or removed are located in the confined space of the groove, and the nuts cannot be tightened or removed with conventional tool spanners or dead wrenches. Therefore, it is necessary to design and process a special tool suitable for fastening or dismounting the connecting nut in the confined space of the groove.

Contents of the invention

The purpose of the utility model is to provide a simple, easy-to-process and reasonable-structured tool for loading and unloading fastening nuts in the restricted space of grooves or holes.

In order to achieve the above object, the technical scheme adopted by the utility model is:

A nut loading and unloading tool in a confined space, including a nut clamp, a torque transmission rod, and a handle rod. The nut clamp is welded to the torque transmission rod, and the torque transmission rod is welded to the handle rod. The nut clamp is cylindrical , the end surface of the cylinder is provided with a regular hexagonal groove, and then the adjacent two sides of the regular hexagonal groove are cut off along the axis of the cylinder.

The material of the handling tool is stainless steel.

The beneficial effects obtained by the utility model are:

The utility model can meet the fastening or dismounting operation of the nut in the limited space of the groove or the hole during the installation and disassembly process of the equipment or living utensils, and the tool is convenient to process, use and operate.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1 and Fig. 2, the nut loading and unloading tool in a confined space described in the utility model includes a nut clamp 1, a torque transmission rod 2, and a handle rod 3, and the nut clamp 1 is welded with the torque transmission rod 2, The torque transmission rod 2 is welded with the handle bar 3, the nut fixture 1 is cylindrical, and the end face of the cylindrical shape is provided with a regular hexagonal groove, and then the adjacent two sides of the regular hexagonal groove are cut off along the direction of the cylindrical axis. The material of the handling tool is stainless steel.

When in use, extend one end of the nut fixture 1 into the restricted groove space, clamp the loading and unloading nut with the slotted part of the nut fixture 1, and hold the hand grip lever 3 to select the direction of force according to the loading and unloading requirements. Rotate the handle bar 3, and transmit the force to the nut fixture 1 through the torque transmission bar 2, so as to carry out the loading and unloading operation of the nut.
