Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, 2, 3 and 4, the bolt disassembling tool comprises an elongated housing 1 and a cover plate 2, wherein the housing 1 and the cover plate 2 are matched to form a mounting cavity; a first chain wheel 11 and a second chain wheel 12 are arranged in the mounting cavity, and a chain 13 is meshed between the first chain wheel 11 and the second chain wheel 12; a first rotating shaft 111 is fixed on the first chain wheel 11; a second rotating shaft 121 is fixed on the second chain wheel 12, and the first rotating shaft 111 and the second rotating shaft 121 are respectively and rotatably connected with the shell and the cover plate through bearings 16; a rotating rod 112 is fixed on the end surface of the first rotating shaft 111, a connector 122 is fixed on the end surface of the second rotating shaft 121, and a clamping wheel 123 is fixed in the middle of the second rotating shaft 121; a sliding groove 21 is formed in the cover plate 2, a sliding block 22 is connected in the sliding groove 21 in a sliding mode, and a clamping rod 23 is fixed on the sliding block 22; the latch lever 23 can restrict the rotation of the latch wheel 123.

The connector 122 of the disassembling tool can be provided with hexagonal sleeves with various specifications, and a proper sleeve can be selected and arranged on the connector 122; then the rotating rod 112 is inserted into the clamping jaw of the electric batch (or the electric hand drill) to be clamped; then, the sleeve is sleeved on the bolt head to be disassembled (or assembled), the electric screwdriver is started, and the sleeve is driven to rotate by the rotating rod 112, the first chain wheel 11, the chain 13 and the second chain wheel 12, so that the disassembling or assembling of the bolt is realized. The disassembling tool adopts the electric tool as a power source, so the disassembling or the assembling of the bolt can be quickly completed, and the efficiency of equipment maintenance is greatly improved. Simultaneously, because the bolt that has is in narrow and small space department in the equipment, electric tool such as electric screwdriver, electric hand drill can't get to accomplish work in it, so can realize the skew of electric tool's impetus through this extracting tool, and then make it accomplish the quick dismantlement or the installation to bolt in the narrow and small space.

Some bolts are difficult to rotate due to the fact that the bolts are not moved for a long time, and cannot be loosened only by depending on power provided by an electric tool, so that a clamping wheel 123 and a clamping rod 23 mechanism are arranged in the disassembling tool, under the limiting effect of the clamping wheel and the clamping rod, the rotating of the sleeve can be realized through the disassembling tool of the swinging plate, a manual disassembling mode is started, and the bolts are loosened.
