Description

Mounting tool is assisted to screw

Technical Field

The utility model belongs to the technical field of the appurtenance field of apparatus installation and specifically relates to a mounting tool is assisted to screw is related to.

Background

In the field of structural fixation, the fixation by using a nail head part is the simplest and practical method. The basic operation is to pass the nail head part through the other part through holes and then fix it on the final part, and the nail head presses all parts tightly. The most common use scenario is to fix the part on the component with the threaded hole by using a screw, and a simple fastening tool such as a screwdriver or a wrench is usually used to fix and fasten the screw. For convenient and fast installation, fastening tools such as a screwdriver or a wrench and the like are generally magnetic, so that the screw can be attached to the wrench in the installation process and is not easy to fall off. However, this is based on a precondition: the main body of the screw is made of iron. If the screw is not allowed to be iron under certain conditions, such as the conditions that the screw is wet and easy to embroider or has high requirements on the strength of the screw, the screw made of plastic or other metal materials is needed, at the moment, the magnetism of the tool cannot play a role, the phenomenon that the screw falls off frequently occurs in the installation process, and great instability is brought to the assembly. To prevent accidental occurrences and reduce the error rate, such situations often use robots instead of tools. The manipulator not only increases the use cost, but also cannot be operated under the condition of narrow space. Therefore, the market urgently needs an auxiliary mounting device which can assist a tool to mount a nailed component in a very small space.
