[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-6 As shown, this utility model provides a technical solution: a multifunctional forest tending handcart, including: a mounting frame 1, moving wheels 2, a support frame 3, a frame body 4, a lead screw 5, a nut 6, a limiting block 7, a sliding groove 8, a sliding block 9, a rigid claw 10, a flexible claw 11, a rubber gasket 12, a sealing block 13, a bolt 14, a connecting rod 15, a slot 16, a moving block 17, a handle 18, and a threaded rod 19.

[0036] In existing handcarts, tools are typically carried inside the cart. However, when traversing bumpy roads, the tools are prone to colliding, generating annoying noise pollution and potentially causing damage. Furthermore, the fixed height of the handcart's handles, which cannot be adjusted to accommodate different user heights, significantly limits its convenience and comfort, failing to meet diverse usage needs. Therefore, there is room for further improvement.

[0037] A multifunctional forest tending handcart includes: a mounting frame 1, with movable wheels 2 on the lower side of the mounting frame 1 and a support frame 3 on the upper side of the mounting frame 1, the upper side of the mounting frame 1 being rotatably connected to a frame body 4 via a connecting component; a clamping mechanism for convenient placement of tools is provided on the side of the frame body 4, and a sliding groove 8 is provided on the side of the frame body 4, the sliding groove 8 being symmetrical about the vertical central axis of the frame body 4; an adjustment mechanism for convenient use by people of different heights is provided on the side of the mounting frame 1, and a connecting rod 15 is provided on the upper right side of the mounting frame 1, the connecting rod 15 being symmetrical about the vertical central axis of the mounting frame 1.

[0038] A lead screw 5 is provided on the upper side of the mounting frame 1. The lead screw 5 is threadedly connected to a nut 6. The lower side of the nut 6 is tightly fitted with a limiting block 7, which is located on the lower right side of the frame 4. A sliding block 9 is slidably connected to a sliding groove 8. The sliding block 9 is fixedly connected to a rigid claw 10 and a flexible claw 11, with the flexible claw 11 located above the rigid claw 10. Rubber gaskets 12 are provided on the inner sides of both the rigid claw 10 and the flexible claw 11. A sealing block 13 is slidably connected inside the sliding groove 8. The sealing block 13 is threadedly connected to a bolt 14, which is also threadedly connected to the sliding groove 8.

[0039] The slot 16 is formed inside the connecting rod 15. The slot 16 is slidably connected to the moving block 17, and the moving block 17 is threadedly connected to the threaded rod 19. The threaded rod 19 is rotatably connected to the connecting rod 15, and the moving block 17 is fixedly connected to the handle 18. The slot 16, the moving block 17, the handle 18, and the threaded rod 19 all correspond one-to-one with the connecting rod 15.

[0040] Working principle:

[0041] like Figure 1 , Figure 3 and Figure 5 As shown, before carrying out forest tending operations, the sliding block 9 is moved within the sliding groove 8 according to the size of the tools to be carried, such as pruning shears and shovels. The distance between the rigid claw 10 and the flexible claw 11 is adjusted. The rear side of the sliding block 9 has a relatively large friction with the frame 4, making it difficult for the tool to move within the sliding groove 8 via the sliding block 9 during movement. The tool is placed between the rigid claw 10 and the flexible claw 11. The flexible claw 11 can slightly deform to adapt to the tool's contour, and the inner rubber pad 12 fits tightly against the tool's surface, increasing friction and preventing the tool from sliding. Subsequently, the sealing block 13 is slid to the right side of the sliding groove 8, and the bolt 14 is tightened to fix the sealing block 13 to the sliding groove 8, restricting the movement of the sliding block 9 and completing the tool fixation, preventing the tool from impacting when the cart is moved.

[0042] When replacing the sliding block 9, remove the bolt 14 to allow the sealing block 13 to be removed from the sliding groove 8, and then the sliding block 9 can be removed for replacement.

[0043] like Figure 1 and Figure 6 As shown, the height of the handle 18 is adjusted according to the user's height: Rotating the disc on the upper side of the threaded rod 19 causes the moving block 17 to slide up and down along the slot 16, as the threaded rod 19 is threadedly connected to the moving block 17 and rotatably connected to the connecting rod 15. The moving block 17 is fixedly connected to the handle 18, thus causing the handle 18 to rise and fall synchronously until a comfortable height for the user is reached. Rotating the threaded rod 19 then stops, and the moving block 17 remains fixed in position under the threaded locking action of the threaded rod 19, completing the armrest height adjustment.

[0044] like Figure 1 and Figure 4 As shown, when materials such as fertilizer and seedlings need to be transported, the materials are placed in the frame 4, and the user holds the handle 18 to push the cart. The moving wheels 2 on the lower side of the mounting frame 1 roll on the forest road, and the support frame 3 supports the upper structure of the mounting frame 1 to ensure the stability of the cart during movement.

[0045] like Figure 1 and Figure 2 As shown, when it is necessary to empty the material inside the frame 4, loosen the nut 6. The nut 6 moves downward along the screw 5, causing the limiting block 7 to move downward simultaneously, releasing the support on the right side of the frame 4. Then, rotate the frame 4 around the connecting assembly between the mounting frame 1 and the frame 4, causing the frame 4 to tilt, and the internal material will pour out in the tilting direction. After the material is poured out, rotate the frame 4 in the opposite direction to reset it, and loosen the nut 6 to move upward, causing the limiting block 7 to re-fit tightly against the lower right side of the frame 4, thus fixing the frame 4.
