Description

technical field [0001] The invention relates to the field of screws, in particular to an anti-dropping fixing screw. Background technique [0002] The fixing screw is an indispensable small part in our life and work. The general fixing screw can achieve a good fixing effect in most cases, but like various containers and suitcases during transportation, and various parts fixedly connected with the vibrator For items such as collection boxes that have been in vibration for a long time, if there are general fixing screws installed in them, they need to be fixed and inspected within a certain period of time to prevent the fixing screws from falling off from the screw holes during vibration and affect the stability of the items. Contents of the invention [0003] The problem to be solved by the present invention is to provide an anti-falling fixing screw with a locking part at the bottom. [0004] In order to solve the above-mentioned technical problems, the technical solution...
