[0028] The extension mechanism includes a guide component and a limit component. A matching cavity hole 6 is opened at the top of one end of the hand-held rod 1. The matching cavity hole 6 is connected to the inner side of the hand-held rod 1. The inner side of the matching cavity hole 6 is equipped with a guide component, and the inner side of the guide component is equipped with a limit component.

[0029] The guide assembly includes a carrying movable column 7, an auxiliary top plate 8, a through cavity 9 and a first connecting spring 10. The carrying movable column 7 is slidably connected to the inner side of the matching cavity hole 6. A through cavity 9 is opened on the inner side of the carrying movable column 7. The through cavity 9 is slidably connected to the extension rod 2. The first connecting spring 10 is fixed to the top of the inner side of the through cavity 9. The auxiliary top plate 8 is fixed to one end of the first connecting spring 10. Both ends of the auxiliary top plate 8 are fixed to the inner side of the matching cavity hole 6. The auxiliary top plate 8 is slidably connected to the through cavity 9. A rubber pad is provided on the top of the carrying movable column 7 to facilitate force protection for the user's hands.

[0030] The guide assembly includes a limiting tooth head 11 and a bottom tooth groove 13.

A plurality of bottom tooth grooves 13 corresponding to the positions of the limiting tooth heads 11 are evenly opened on the bottom of the extension rod 2. The bottom tooth grooves 13 are slidably connected to the limiting tooth head 11. Through the arrangement of the limiting tooth head 11 and the bottom tooth grooves 13, it is convenient to limit the extension rod 2 on the inner side of the through cavity 9 to prevent the extension rod 2 from loosening.

[0031] Example 2

[0032] Embodiment 1 is further optimized, specifically, as Figure 4 As shown, a carrying mechanism is installed between the extension rod 2 and the docking joint 5, and the carrying mechanism is used for connecting the extension rod 2 and the docking joint 5.

[0033] The carrying mechanism includes a docking groove 12, an insertion interface 14, a force-applying pulling column 15, a square plate 16, a quick plug block 17 and a second connecting spring 18. The side of the docking joint 5 away from the connecting ring 3 is provided with a plug-in interface 14, and the plug-in interface 14 is slidably connected to the extension rod 2. Both ends of the docking joint 5 are slidably connected with the force-applying pulling column 15. The inner side of the docking joint 5 and the positions at both ends of the plug-in interface 14 are provided with an inner groove, and one end of the force-applying pulling column 15 passes through the inner groove and is fixed with a square plate 16. The square plate 16 is slidably connected to the inner groove, and one end of the square plate 16 Quick-insertion blocks 17 are fixed on both sides, and the quick-insertion blocks 17 are slidably connected to the docking joint 5. The outer side of the force-applying pulling column 15 and the position inside the inner connecting groove are slidably connected with the second connecting spring 18.

When the extension rod 2 needs to be separated from the docking joint 5, the two force-applying pulling columns 15 are pulled until the square plate 16 drives the quick-insertion blocks 17 to separate from the docking grooves 12, and then the extension rod 2 can be pulled out from the plug interface 14.

[0034] One end of the quick-insertion block 17 is provided with an inclined surface. When the extension rod 2 needs to be connected to the docking joint 5, the extension rod 2 is inserted into the plug-in port 14. The setting of the inclined surface makes it easy for the extension rod 2 to push the quick-insertion block 17 into the inner groove through the inclined surface, thereby realizing the quick connection between the docking groove 12 and the quick-insertion block 17.

[0035] From the above, we can know that:

[0036] The utility model aims at the following technical problems: the existing technology can realize the salvage of algae during use, but it is not convenient to adjust the length of the hand-held rod when salvaging algae at different distances on the water surface, and it is not convenient to replace the salvage net when it is damaged; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0037] During use, when the total length of the hand-held rod 1 and the extension rod 2 needs to be adjusted, the carrying movable column 7 is pressed so that the carrying movable column 7 squeezes and contracts the first connection spring 10, thereby separating the limit tooth head 11 from the bottom tooth groove 13, and then the extension rod 2 is pulled so that the extension rod 2 extends or retracts from the hand-held rod 1. When the adjustment is completed, the carrying movable column 7 is released. At this time, the elastic force generated by the first connection spring 10 pushes the carrying movable column 7 to reset upward, thereby causing the carrying movable column 7 to drive the limit tooth head 11 to reset upward until the limit tooth head 11 is connected to the bottom tooth groove 13;

[0038] When the connecting ring 3 or the salvage net 4 is damaged, the two force-applying pulling columns 15 are pulled, so that the force-applying pulling columns 15 drive the block plate 16 to squeeze the second connecting spring 18 to contract, until the block plate 16 drives the quick-insertion block 17 to separate from the docking groove 12, and then the extension rod 2 is pulled out from the plug interface 14, and a new connecting ring 3 and salvage net 4 are replaced, and the extension rod 2 is inserted into the plug interface 14 on the new docking joint 5, and then the force-applying pulling column 15 is released. At this time, the elastic force generated by the second connecting spring 18 pushes the block plate 16 to move until the quick-insertion block 17 is inserted into the corresponding docking groove 12, so that the connection between the extension rod 2 and the docking joint 5 can be achieved.

[0039] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0040] 1. The utility model uses the structural design of the extension mechanism to make it easy to adjust the distance between the hand-held rod 1 and the extension rod 2, so that the user can fish algae at different positions, thereby improving the flexibility of the device.
