However, the machine is not universal, and must be periodically inspected and maintained for a long time to maintain the service life, and parts which do not meet the requirements must be replaced to maintain safety protection if the machine has any parts. However, in the whole machine, since the volume of the screw and the nut is too small, the problems such as dropping and losing of the screw and the nut are easily caused during the maintenance, and therefore, a hand tool is often used for the operation and maintenance to avoid the problems.

However, the main functions of the screw and the nut are to be screwed together to fix the components inside the relevant machine, so as to prevent the machine from vibrating during operation and the internal components from falling off due to large vibration, which may affect the operation of the whole machine, so that the relevant personnel may use the hand tool to lock, tighten and disassemble the screw and the nut together for construction, although the hand tool is operated vigorously to firmly fix the components inside the machine, and the screw and the nut are fixed firmly, and the screw and the nut are disassembled for maintenance, the screw and the nut are easily damaged due to excessive force application, so that the screw and the nut originally having corners are deformed, and the original polygonal shape is changed into a shape without corners (approaching to a circular shape), and long-term screwing and unscrewing are also one of the original shapes of the screw and the nut, which may cause that the user cannot smoothly change the screw and the nut with the hand tool in the future, The nut is disassembled and locked, and finally the screw and the nut are disassembled by a destructive method, so that the defects of time and labor waste, unnecessary payment (replacement of new screw and nut) and the like are increased. Therefore, the related manufacturers must think again how to improve the screw and nut, so as to allow the user to take out the screw and nut in a smooth and undamaged manner.

In view of the above, the present inventors have invested much time in studying related knowledge, comparing the merits with each other, conducting research and development of related products, and going through many experiments and tests, and finally have developed a kind of fixing tool device to improve the above-mentioned shortcomings, so as to meet the needs of the public.
