Abstract

The invention relates to the technical field of dismounting tools, in particular to an equal-distance thread progressive type small bolt dismounting tool and a using method. The tool is matched with ahexagonal open wrench for converting a screwdriver or wrench dismounting fastening way which is difficult to implement in a narrow space into a hexagonal open wrench fastening way which is convenientto operate in a wide space, so that the problems such as screwdriver or wrench partial screwing or inclined screwing as a common screwdriver or wrench cannot be normally used if there is no enough operation space in a dismounting process in the prior art are solved; through engagement of a planetary wheel, a first gear and an inner gear, equal-thread advance and retract effect between a performing head and a bolt is realized based on gear variable-speed transmission principle when a drive sleeve rotates, so that the performing head is always tightly combined with a bolt head for synchronous advance and retract, and thus, bolt head damages caused by slip or inclination under force are avoided, and normal and effective transmission of torsion force moment is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of assembly and disassembly tools, in particular to an equidistant thread progressive small-sized bolt assembly and disassembly tool and its use method. Background technique

[0002] Maintenance personnel often encounter the disassembly and assembly of small bolts such as slotted head bolts, torx head bolts and hexagon head bolts in narrow spaces when performing maintenance on mechanical equipment of generator sets. The screwdriver or wrench cannot be used normally, and the screwdriver or wrench is often prone to biased or oblique screwing, which can easily lead to damage to the bolt head and increase the difficulty of disassembling the bolt. In severe cases, the bolt cannot be disassembled normally, and when installing the bolt , It is also prone to the situation that the bolts are difficult to tighten in place.

[0003] At present, tools such as internal and external hexagonal wrenches, socket adapter wre...
