[0020] It should be noted that in order to fix the extended telescopic rod, each telescopic tube is installed with a bolt to fix the telescopic tube after movement; the telescopic rod 1, mounting part 2, sickle head 3 and cutting blade 4 are made of carbon steel alloy with light weight and high toughness.

[0021] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a clamping assembly 5 is provided on the side wall of the sickle head 3; wherein the clamping assembly 5 includes a mounting box 51, two clamping plates 52 and a power assembly; the mounting box 51 is detachably mounted on the side wall of the sickle head 3 by bolts, and the two clamping plates 52 are symmetrically slidably arranged in the inner cavity of the mounting box 51 (the clamping plates 52 move along the length extension direction of the sickle head 3), and the bottom ends of the two clamping plates 52 extend to the bottom outside of the mounting box 51; the power assembly includes two second elastic members 56 (springs, which are in a compressed state), two moving blocks 58, two limit blocks 59 and a control assembly, and the two second elastic members 56 are respectively arranged between the two clamping plates 52 and the mounting box 51, and the two The two moving blocks 58 are respectively installed on the top walls of the two splints 52, and two storage grooves are opened on the top of the inner cavity of the installation box 51. The two limit blocks 59 are respectively slidably arranged in the two storage grooves (the limit blocks 59 can move up and down, and a spring is installed between the limit blocks 59 and the storage groove, and the spring provides support force for the limit blocks 59). The two limit blocks 59 are located on the inner sides of the two moving blocks 58, and the two fit together; the control component includes a flexible pulling member 57 (such as a rope) and a connecting rod 7, one end of the flexible pulling member 57 is connected to the connecting rod 7, and the other end is connected to the two limit blocks 59 respectively, and the end of the connecting rod 7 away from the flexible pulling member 57 is connected to the pressing block 62.

[0022] Working principle: After extending the telescopic rod 1, move the telescopic rod 1 so that the sickle head 3 hooks the sampled branch and presses it downward; then pull the flexible connecting piece 63 to move the pressure block 62, and pull the flexible pulling piece 57 with the connecting rod 7 to move the limit block 59 up and out of contact with the moving block 58, thereby releasing the restriction on the splint 52; under the action of the second elastic member 56, the two splints 52 move together to clamp the hooked forest branch; the movement of the pressure block 62 will also cause the cutting blade 4 to rotate closer to the sickle head 3, which is used to cut off the hooked sickle head 3, move the telescopic rod 1, pull down the cut branch, and complete the sampling.

[0023] It should be noted that the clamping assembly 5 is reset by manual reset; the side wall where the two limit blocks 59 are close to each other is a slope or an arc surface, so that when the splint 52 is reset, the moving block 58 contacts the slope of the limit block 59, which will push the limit block 59 into the storage groove, so that the moving block 58 passes over the limit block 59.

[0024] In this embodiment, as a further optimization solution, please refer to Figure 3 and Figure 4 The second spring 523 is used to push the movable plate 522 downward, thereby increasing the length of the clamping plate 52 and ensuring that the clamping plate 522 can clamp the sampled branches.

[0025] In this embodiment, as a further optimization solution, please refer to Figure 3The movable plate 522 slides away from the side of the movable plate 521 and is provided with a supporting block 54. A first elastic member 55 (spring) is provided between the movable plate 522 and the supporting block 54. The moving direction of the supporting block 54 is the same as the moving direction of the movable plate 521. The supporting block 54 is under the clamped branches to prevent the branches from escaping from between the two splints 52, and the supporting block 54 slides at the bottom of the movable plate 522 so that it does not affect the two splints 52 from moving closer together; an elastic block 53 (rubber material) is provided on the side wall where the two movable plates 522 are close to each other. The elastic block 53 has a certain flexibility. When the two splints 52 move closer to each other, the elastic block 53 contacts the branch, which will cause the elastic block 53 to be squeezed and deformed, so that the elastic block 53 can fully contact the branch, ensuring that the splint 52 stably clamps the branch.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
