Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of support protection tool for bolt disassembly, including symmetrical 1 He of the first mounting blocks
Second mounting blocks 2 are rotatably connected to shaft 3 in second mounting blocks 2, and 3 outer ring fixing sleeve of shaft is connected to two groups of symmetrical
One bevel gear 4, two groups of first bevel gears 4 side close to each other are engaged with second bevel gear 6, and 6 inner ring of second bevel gear is solid
Surely it is socketed with the screw rod 5 being rotatablely connected with the second mounting blocks 2, screw rod 5 stretches out one end outer ring and the first installation of the second mounting blocks 2
1 screw thread of block is socketed, and the first mounting blocks 1 and the second mounting blocks 2 side-lower close to each other are welded with arc block 7, two groups of arcs
The side close to each other of shape block 7 slidably connects two groups of symmetrical sliding blocks 8, and side of the sliding block 8 far from arc block 7 is hinged
There are connecting rod 9, the one end of connecting rod 9 far from sliding block 8 to be hinged with arc panel 10, the first mounting blocks 1 and 2 bottom of the second mounting blocks peace
Equipped with the first part 13, through-hole is offered in the first part 13, the side that two groups of arc blocks 7 are located remotely from each other is supported with through-hole inner ring
It connects, 13 top side of the first part is installed with the second part 12, and 12 bottom of the second part offers the first threaded hole, two groups
The side close to each other of arc block 7 offers sliding slot, and sliding slot madial wall is slidably connected with sliding block 8, and two groups of sliding blocks 8 are close to each other
Side be fixedly connected with the first spring, two groups of arc panels 10 equal sliding sleeve in side both ends outer end close to each other is connected to casing
