Detailed Description

The utility model relates to a sleeved combined wrench, which consists of an outer sleeve wrench 1, an inner sleeve wrench 2 and a core barrel wrench 3, wherein the outer sleeve wrench 1, the inner sleeve wrench 2 and the core barrel wrench 3 are sequentially and in clearance fit with one another from outside to inside, the front ends of the outer sleeve wrench 1, the inner sleeve wrench 2 and the core barrel wrench 3 are a hexagonal wrench opening I7, a hexagonal wrench opening II 8 and a hexagonal wrench opening III 13 which have different calibers and can be nested inside and outside, and the inner hexagon and the outer hexagon of the hexagonal wrench opening I7 and the hexagonal wrench opening II 8 can be used for mounting or dismounting bolts and nuts with different specifications; the outer hexagon of the core barrel spanner 3 can be used for installing or disassembling bolts and nuts, the inner sleeve spanner 2 and a spanner I9 and a spanner II 10 of the core barrel spanner 3 are cylinders which can be mutually overlapped and have the same cross-sectional shapes with a hexagon spanner opening II 8 and a hexagon spanner opening III 13, the length of the spanner I9 is smaller than that of the spanner II 10, two annular convex edges are fixed on the columns of the first trigger I9 and the second trigger II 10, rotating rings are rotatably arranged at grooves formed between the two annular convex edges, a key handle I4 and a key handle II 11 are respectively fixed on the two rotating rings, a track groove 5 for the operation of the key handle I4 and the key handle II 11 is longitudinally arranged on the pipe wall of the outer sleeve wrench 1, the key handle I4 and the key handle II 11 penetrate through the track groove 5 and can slide in the track groove 5 to operate, and more than one bayonet 6 capable of being embedded into the key handle I4 and the key handle II 11 is arranged on each of two sides of the track groove 5; the tail end pipe of the outer sleeve wrench 1 is also provided with an inner angular wrench opening 12 for mounting or dismounting bolts and nuts with other shapes.

When in use, the outer socket wrench 1, the inner socket wrench 2 or the core barrel wrench 3 can be selected to be used according to the requirement. When the outer socket wrench 1 is used, as shown in fig. 3, the key handle i 4 and the key handle ii 11 are placed in the track groove 5, the key handle i 4 and the key handle ii 11 are pulled backward, so that the inner socket wrench 2 and the core barrel wrench 3 are completely placed inside the outer socket wrench 1, and then the key handle i 4 and the key handle ii 11 are respectively inserted into the bayonets 6 at both sides of the track groove 5, so that the inner socket wrench 2 and the core barrel wrench 3 are prevented from sliding inside the outer socket wrench 1.

When the inner socket wrench 2 is used, as shown in fig. 2, the key handle i 4 and the key handle ii 11 are placed in the track groove 5, the key handle ii 11 is pulled backwards while the key handle i 4 is pulled forwards, so that the hexagonal wrench opening ii 8 of the inner socket wrench 2 is placed outside the outer socket wrench 1, the core barrel wrench 3 is completely placed inside the inner socket wrench 2, and the key handle i 4 and the key handle ii 11 are respectively embedded into the bayonets 6 on two sides of the track groove 5, so that the inner socket wrench 2 and the core barrel wrench 3 are prevented from sliding inside the outer socket wrench 1.

When using core barrel spanner 3, as shown in fig. 1, arrange key handle I4 and key handle II 11 in track groove 5, pull key handle I4 and key handle II 11 forward simultaneously, make inner skleeve spanner 2 and core barrel spanner 3's hexagonal spanner opening II 8, hexagonal spanner opening III 13 all arrange outer sleeve spanner 1 outside in, and core barrel spanner 3's hexagonal spanner opening III 13 arranges inner skleeve spanner 2 outside completely, imbed respectively key handle I4 and key handle II 11 in the bayonet socket 6 of track groove 5 both sides again, prevent that inner skleeve spanner 2 and core barrel spanner 3 from sliding in outer sleeve spanner 1 is inside.

When encountering other shapes of bolts or nuts, the internal angular wrench opening 12 in the end tube of the outer sleeve wrench 1 can be used for installation or removal.
