Figure 10 for Figure 1 The diagram shows a third-view operation of the telescopic object retrieval rod. Figure 11 for Figure 1 The diagram shows a fourth-view operation schematic of the telescopic retrieval pole. A multi-functional telescopic retrieval pole suitable for fire rescue includes:

[0048] Telescopic rod 1, circular fixing sleeve 2, extrusion assembly 3, movable limiting sleeve 4, movable assembly 5, first operating component 7, second operating component 8, third operating component 9, multiple circular fixing blocks 10 and multiple fixing holes 11;

[0049] The circular fixing sleeve 2 is connected to one end of the telescopic rod 1. The extrusion assembly 3 is disposed on one side of the circular fixing sleeve 2. The extrusion assembly 3 includes a fixing rod 31, two movable sleeves 32, two movable frames 33, multiple circular limiting blocks 34, and a spring 35. The fixing rod 31 is connected to the inside of the circular fixing sleeve 2. The two movable sleeves 32 are respectively fitted on both sides of the surface of the fixing rod 31. The two movable frames 33 are respectively connected to one side of the two movable sleeves 32. The multiple circular limiting blocks 34 are respectively connected to the opposite side of the two movable frames 33. The spring 35 is fitted on the surface of the fixing rod 31 and is located between the two movable sleeves 32.

[0050] The movable limiting sleeve 4 is movably fitted onto the surface of the circular fixed sleeve 2;

[0051] The movable component 5 is disposed on the surface of the circular fixing sleeve 2;

[0052] Multiple circular fixing blocks 10 are respectively connected to one end of the first operating member 7, the second operating member 8 and the third operating member 9, and multiple fixing holes 11 are respectively opened on the surface of the multiple circular fixing blocks 10.

[0053] The first operating component 7, the second operating component 8, and the third operating component 9 can be hooks, waist ropes, and D-shaped movable ropes, or triangular claw hooks, elastic catchers, buoyancy bars, and arc-shaped scoops, thus enabling multiple multi-functional uses.

[0054] The movable component 5 includes two movable slots 51, two movable blocks 52, a fixing bolt 53, and two fixing through holes 54. The two movable slots 51 are symmetrically opened on the surface of the circular fixing sleeve 2. The two movable blocks 52 are slidably connected to the interior of the two movable slots 51 respectively. The surface of the movable block 52 is connected to the inner wall of the movable limiting sleeve 4.

[0055] The use of spring 35 makes it easy to return to the original position through movable sleeve 32 when the two movable frames 33 are not compressed. The size of the fixing hole 11 on the surface of the circular fixing block 10 is adapted to the size of the circular limiting block 34. At the same time, the position of the fixing hole 11 on the surface of the circular fixing block 10 corresponds to the position of the circular limiting block 34 on the movable frame 33.

[0056] The fixing bolt 53 is disposed between the two movable blocks 52 and the circular fixing sleeve 2, and the two fixing through holes 54 are respectively opened inside the two movable grooves 51.

[0057] A handle 12 is provided on one side of the surface of the telescopic rod 1.

[0058] The adjustment and fixing of the telescopic rod 1 are the same as the size adjustment and fixing of the fishing rod. The telescopic rod 1 is composed of multiple movable connecting rods.

Then, by pressing the movable frame 33 with multiple circular limiting blocks 34 on both sides of the circular fixing sleeve 2, under the action of the fixing rod 31 and the two movable sleeves 32, the multiple circular limiting blocks 34 are connected to the multiple fixing holes 11 on the surface of the circular fixing block 10. At the same time, when the two movable frames 33 move the movable sleeves 32 respectively, they compress the springs 35 on the surface of the fixed rod 31. When the two movable frames 33 with circular limit blocks 34 are completely in contact with the circular fixed block 10, the movable limit sleeve 4 is pushed and placed on the surface of the two movable frames 33 under the action of the movable block 52 and the movable groove 51. Then, the fixed bolt 53 is connected to the fixed through hole 54 between the two movable blocks 52 and the circular fixed sleeve 2. Then, the telescopic rod 1 is adjusted to a suitable length for the use of the first operating component 7, the second operating component 8, or the third operating component 9.
