Detailed Implementation
[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0034] Please see Figure 1-18 A garden tool with a novel telescopic component includes a handle 1 and a working body 2, with a telescopic rod assembly 3 connecting the handle 1 and the working body 2.
[0035] The telescopic rod assembly 3 in this utility model can be applied to various electric garden tools, such as Figure 1 Electric chainsaws, such as Figure 18 The blower in the picture can also be used for electric garden tools such as trimmers and hedge trimmers.
[0036] The telescopic rod assembly 3 includes an outer tube 4 and an inner tube assembly 5. One end of the outer tube 4 is connected to the handle 1, and the inner tube assembly 5 is movably disposed inside the outer tube 4. The other end of the inner tube assembly 5 is connected to the working body 2. A limiting member 6 is provided on the outer periphery of the telescopic rod assembly 3 to restrict the movement of the inner tube assembly 5. The limiting member 6 is movably disposed inside the handle 1. One end of the limiting member 6 extends out of the handle 1 and is provided with an unlocking button 7. A limiting part 8 is formed inside the limiting member 6. Several limiting holes are opened on the side wall of the telescopic rod assembly 3 for the limiting part 8 to be inserted, thereby restricting the movement of the telescopic rod assembly 3. The movement of the telescopic rod assembly 3 can be released by operating the unlocking button 7, thereby adjusting the length for use.
[0037] This utility model, through the design of the telescopic pole assembly 3, allows for the use of the extended working body 2 during actual use, facilitating the pruning and cleaning of branches at higher locations. It is convenient to operate and, compared to existing methods, eliminates the need for auxiliary equipment to climb to higher locations, making it safer, more reliable, and more efficient.
[0038] See details Figure 3 The telescopic rod assembly 3 in this utility model can adopt a two-section design, depending on different actual usage conditions. Figure 2 Alternatively, a three-section design can be adopted, allowing the main body of the machine to extend further.
[0039] When a three-section design is adopted, the inner tube assembly 5 includes an inner tube 1 9 and an inner tube 2 10 movably disposed on its inner periphery. A limit component 2 11 is provided between the inner tube 2 10 and the inner tube 1 9. By operating the limit component 2 11, the relative displacement between the inner tube 2 10 and the inner tube 1 9 can be limited or released for subsequent use.
[0040] The upper end of the outer tube 4 is provided with a limiting block 20, and the side of the inner tube 9 is formed with a sliding groove 21 for the limiting block 20 to slide. The cooperation of the sliding groove 21 and the limiting block 20 improves the stability of the inner tube 9 and the outer tube 4 during relative movement. The lower end of the inner tube 9 is provided with a slider 22, the lower end of which is located within the sliding groove 21. Figure 11 and Figure 13 When the telescopic rod assembly 3 extends to its limit position, the slider 22 abuts against the side wall of the limiting block 20 to restrict the inner tube 9 from continuing to move and prevent it from falling out of the outer tube 4.
[0041] Combination Figure 8 and Figure 9 The upper end of the inner tube 10 is connected to the working body 2, and the lower end of the inner tube 10 is provided with a limiting block 23. The side of the limiting sleeve 12 is equipped with a side cover 24, and a limiting part 3 25 is formed inside the side cover 24 for the limiting block 23 to abut against. When it is necessary to adjust the extension, first press the unlock button 7 to make the limiting part 1 8 leave the second limiting hole 27 and the third limiting hole 28. Then pull the working body 2 to pull the inner tube 10 out of the inner tube 1 9 until the inner tube 10 moves to the limit position. At this time, the telescopic rod assembly is in a partially unfolded state, and the limiting block 23 abuts against the side wall of the limiting part 3 25. Then continue to pull the working body 2. Through the cooperation of the limiting block 23 and the limiting part 3 25, the inner tube 10 can drive the inner tube 1 9 to be pulled out of the outer sleeve 4, so that the telescopic rod assembly continues to extend as a whole, so that the telescopic rod assembly is in a fully unfolded state.
[0042] Combination Figure 5 and Figure 6 The limiting holes include a first limiting hole 26, a second limiting hole 27, and a third limiting hole 28. The upper end of the outer sleeve 4 has a first limiting hole 26, allowing the limiting part 8 to extend into the second and third limiting holes 27 and 28. The upper and lower ends of the inner tube 9 have second limiting holes 27, and the upper end of the inner tube 10 has a third limiting hole 28. When the telescopic rod assembly is in a retracted state, the limiting part 8 passes through the first limiting hole 26 and is locked within the second and third limiting holes 27 and 28, thereby restricting the movement of the telescopic rod assembly and keeping its position fixed. Figure 9 and Figure 13 When the inner tube 9 in the telescopic rod assembly extends, the limiting part 8 passes through the first limiting hole 26 and is locked in the second limiting hole 27, thereby restricting the movement of the inner tube 9.
[0043] The limiting component 2 11 includes a limiting sleeve 12 installed on the outer periphery of the inner tube 1 9. A limiting member 2 13 is movably disposed inside the limiting sleeve 12. The lower end of the limiting member 2 13 extends out of the limiting sleeve 12 and is provided with an unlocking part 14. A limiting part 2 15 is formed inside the limiting member 2 13. The upper and lower ends of the inner tube 2 10 are respectively provided with limiting holes 2 16 for the insertion of the limiting part 2 15. Figure 11 and Figure 12 When the telescopic rod assembly is fully extended, the second limiting part 15 is engaged in the second limiting hole 16 at the lower end of the second inner tube 10, thereby restricting the relative position between the second inner tube 10 and the first inner tube 9. When the telescopic rod assembly is fully extended, the restriction on the relative position movement between the second inner tube 10 and the first inner tube 9 can be released by operating the unlocking part 14. Then the second inner tube 10 can be retracted into the first inner tube 9, so that the telescopic assembly is partially retracted, achieving the effect of shortening the length. At this time, the second limiting part 15 is engaged in the second limiting hole 16 at the upper end of the second inner tube 10, thereby restricting the relative position between the second inner tube 10 and the first inner tube 9.
[0044] A return spring 17 abuts against the limiting member 13 and the limiting sleeve 12, so that the limiting part 15 tends to move closer to the limiting hole 16. The front side of the handle 1 is formed with a limiting wall 18 for the lower end of the limiting member 13 to abut against. Figure 6 and Figure 9 When the inner tube 9 is still inside the outer tube 4, because the lower end of the limiting member 13 abuts against the limiting wall 18, the limiting part 15 will not be stuck into the limiting hole 16, and therefore will not restrict the relative displacement between the inner tube 9 and the inner tube 10. Figure 11 and Figure 12 When the inner tube 19 is pulled out from the outer tube 4, the lower end of the limiting member 2 13 no longer abuts against the limiting wall 18. Due to the action of the reset spring 17, the limiting member 2 13 will be inserted into the limiting hole 2 16, thereby limiting the relative displacement between the inner tube 19 and the inner tube 2 10 and preventing the inner tube 2 10 from falling out of the inner tube 19.
[0045] The front side of the limiting wall 18 is formed with a sliding slope 19. During the process of retracting the telescopic rod assembly, the unlocking part 14 can move along the sliding slope 19 so that the limiting part 2 15 automatically leaves the limiting hole 2 16, thereby releasing the relative displacement restriction between the inner tube 1 9 and the inner tube 2 10.
[0046] A return spring 29 abuts between the lower end of the limiting member 6 and the handle 1, so that the limiting part 8 tends to move closer to the limiting hole.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
