Description

Technical Field

[0001] This utility model relates to the field of agricultural tools, and in particular to a miniature hook shovel. Background Technology

[0002] As a lightweight agricultural tool, the mini hook shovel is widely used for digging trenches and backfilling in confined spaces such as vegetable greenhouses and nurseries. Its design needs to balance operational flexibility and structural strength to meet the precise needs of shallow trench excavation in precision agriculture scenarios.

[0003] Most commercially available mini hook shovels currently use an integrated fixed rod structure, with the handle and shovel head rigidly connected by welding or bolts. During operation, the user applies downward pressure by holding the handle, and uses the wedge-shaped structure of the blade to cut into the soil. In conjunction with the slope protection plate, the soil is guided to flow and form a trench. These tools rely on the integral metal rod to transmit torque. The structure is simple, but the functional expansion is limited.

[0004] However, the traditional fixed-bar structure has significant drawbacks. It cannot adjust the tool length according to the depth of the crop roots or the hardness of the soil. For example, when cultivating shallow-rooted crops, a short handle is required to control the depth of the furrow, while a long handle is required to increase leverage for deep-rooted crops. Users are forced to bend over or change the entire set of tools, which not only exacerbates labor fatigue but also leads to low work efficiency and makes it difficult to meet the requirements of differentiated agronomy. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a miniature hook shovel, which aims to improve the problem that the length of traditional fixed rods cannot be adjusted.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a miniature hook shovel, comprising an inner rod, a curved rod fixedly connected to one end of the inner rod, a connecting block fixedly connected to one end of the curved rod, a connecting column fixedly connected to the outer wall of the connecting block, a trench shovel provided on the outer wall of the connecting column, a slope protection plate fixedly connected to the outer wall of the trench shovel, a connecting assembly provided inside the trench shovel, an outer tube sleeved on the other end of the inner rod, a shovel handle fixedly connected to one end of the outer tube, and a telescopic assembly provided inside the inner rod;

[0007] The telescopic assembly includes a slot and a rod. The slot is formed on the inner wall of the outer tube. The outer wall of the rod is slidably connected to the inner wall of the inner rod. The slot and the rod are engaged. A ring is fitted on the outer wall of the inner rod. An inclined block is slidably connected to the inner wall of the inner rod. One end of the rod is slidably connected to the outer wall of the inclined block. A button is fixedly connected to the outer wall of the inclined block. The outer wall of the button is slidably connected to the inner wall of the ring.

[0008] Furthermore, the connecting assembly includes a screw, a second slot, and a locking block. The second slot is formed on the inner wall of the trench shovel, the outer wall of the locking block is slidably connected to the inner wall of the connecting column, the locking block is engaged with the second slot, the outer wall of the screw is threadedly connected to the outer wall of the trench shovel, and the outer wall of the screw is threadedly connected to the outer wall of the connecting column.

[0009] Furthermore, the inner wall of the connecting column is rotatably connected to two connecting rods, which are cross-connected. The outer wall of the connecting rods is provided with a sliding groove, and the outer wall of the locking block is slidably connected to the inner wall of the sliding groove.

[0010] Furthermore, a spring four is provided inside the connecting column. One end of the spring four is fixedly connected to one end of a connecting rod, and the other end of the spring four is fixedly connected to one end of another connecting rod.

[0011] Furthermore, two buttons are slidably connected to the inner wall of the connecting block, and a connecting rod is fixedly connected to the inner wall of each of the two buttons. The two connecting rods are located at the other end of the two connecting rods.

[0012] Furthermore, a spring three is sleeved on the outer wall of the connecting rod, and one end of the spring three is fixedly connected to the inner wall of the connecting block.

[0013] Furthermore, a spring is sleeved on the outer wall of the lever, and one end of the spring is fixedly connected to the inner wall of the inner rod.

[0014] Furthermore, a second spring is provided inside the inner rod, and one end of the second spring is fixedly connected to the outer wall of the inclined block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the inclined block is driven to slide by pressing the button on the ring sleeve, which forces the locking rod to disengage from the outer tube slot. At this time, the extension and retraction length of the inner rod can be freely adjusted. After releasing the button, the spring automatically pushes the locking rod to reset and lock, realizing the quick adjustment of the shovel handle length with one hand. This design significantly improves the adaptability to different working depth requirements, and the mechanical self-locking structure ensures that the length is stable and does not slip during tillage.

[0017] 2. In this utility model, pressing the buttons on both sides of the connecting block simultaneously causes the locking block to retract and disengage from the trench shovel slot via the linkage mechanism, thus disassembling the trench shovel. After replacing the new shovel head, releasing the button causes the spring to drive the locking block to pop out and complete the pre-fixation. Tightening the screw then achieves double locking. This structure makes trench shovel replacement faster and more convenient, greatly improving maintenance efficiency. At the same time, the mechanical locking and thread reinforcement ensure the reliability of the connection under high-intensity tillage. Attached Figure Description

[0026] Reference Figure 1 - Figure 5This utility model provides an embodiment of a miniature hook shovel, comprising an inner rod 1, one end of which is fixedly connected to a curved rod 2. A connecting block 16 is fixedly connected to one end of the curved rod 2 for connecting the curved rod 2 and the shovel head assembly. A connecting post 17 is fixedly connected to the outer wall of the connecting block 16 for installing and fixing a trench shovel 3. The trench shovel 3 is provided on the outer wall of the connecting post 17 to dig up the soil. A slope protection plate 4 is fixedly connected to the outer wall of the trench shovel 3 to guide the soil during trenching, forming a regular trench wall. A connecting assembly is provided inside the trench shovel 3. An outer tube 5, serving as the outer sleeve of a telescopic rod, is sleeved on the other end of the inner rod 1. A shovel handle 6 is fixedly connected to one end of the outer tube 5 for easy gripping by the user. A telescopic assembly is provided inside the inner rod 1, comprising a slot 7 and a lever 1. 1. The slot 7 is formed on the inner wall of the outer tube 5 to embed and engage the locking rod 11. The outer wall of the locking rod 11 is slidably connected to the inner wall of the inner rod 1. When the slot 7 and the locking rod 11 are engaged and locked, it prevents the inner and outer rods from sliding relative to each other. The outer wall of the inner rod 1 is fitted with a ring 8 to provide a button mounting point. The inner wall of the inner rod 1 is slidably connected to a wedge 10 to convert the pressing motion of the button into the lateral movement of the locking rod 11. One end of the locking rod 11 is slidably connected to the outer wall of the wedge 10. The inclined surface of the wedge 10 drives the locking rod 11 to move. The outer wall of the wedge 10 is fixedly connected to a button 9. Pressing the button 9 unlocks the extension and retraction. The outer wall of the button 9 is slidably connected to the inner wall of the ring 8. The connecting assembly includes a screw 14, a slot 15, and a locking block 22 for double locking to ensure connection. The trench shovel 3 is securely positioned. The second slot 15 is formed on the inner wall of the trench shovel 3. The outer wall of the locking block 22 is slidably connected to the inner wall of the connecting column 17. The locking block 22 engages with the second slot 15 to achieve pre-positioning and prevent detachment of the trench shovel 3. The outer wall of the screw 14 is threadedly connected to the outer wall of the trench shovel 3 and the outer wall of the connecting column 17, rigidly connecting the trench shovel 3 and the connecting column 17. Two connecting rods 20 are rotatably connected to the inner wall of the connecting column 17. The two connecting rods 20 are cross-connected to form a scissor-type linkage. A sliding groove 21 is formed through the outer wall of the connecting rod 20 to restrict the movement trajectory of the locking block 22. The outer wall of the locking block 22 is slidably connected to the inner wall of the sliding groove 21. The rotation of the connecting rod 20 drives the locking block 22 to move linearly through the sliding groove 21. A spring is installed inside the connecting column 17. Spring 23, with one end fixedly connected to one end of a connecting rod 20 and the other end fixedly connected to one end of another connecting rod 20, provides a spring force to push the locking block 22 outward and maintain the connecting rod 20 in an unfolded state. Two buttons 24 are slidably connected to the inner wall of the connecting block 16; pressing them simultaneously unlocks the trench shovel 3 to prevent accidental activation from one side. Connecting rods 18 are fixedly connected to the inner walls of both buttons 24, and both connecting rods 18 are located at the other ends of the two connecting rods 20. A spring 19 is sleeved on the outer wall of each connecting rod 18 to provide a reset spring force for the buttons. One end of the spring 19 is fixedly connected to the inner wall of the connecting block 16. A spring 12 is sleeved on the outer wall of the locking rod 11 to provide a spring force to push the locking rod 11 outward into the locking groove.One end of the spring 12 is fixedly connected to the inner wall of the inner rod 1. A second spring 13 is installed inside the inner rod 1 to provide the elastic force for the inclined block 10 to return to its original position. One end of the second spring 13 is fixedly connected to the outer wall of the inclined block 10.

[0027] Working principle: When using this mini hook shovel, the operator first holds the shovel handle 6. If the working length needs to be adjusted, press button 9 on the ring sleeve 8 with your thumb to drive the inclined block 10 to slide inside the inner rod 1, forcing the locking rod 11 to disengage from the slot 7 on the inner wall of the outer tube 5. At this time, the spring 13 is compressed and stored energy, and the inner rod 1 can freely extend and retract inside the sleeved outer tube 5. After releasing button 9, the spring 12 pushes the locking rod 11 back into the slot 7, and at the same time, the spring 13 causes the inclined block 10 to return to its position, realizing one-handed quick length locking. When the trench shovel 3 is worn and needs to be replaced, first remove the screw 14, and then press the buttons 24 on both sides of the connecting block 16 simultaneously to push... The connecting rod 18 compresses the spring 19, and the connecting rod 18 drives the cross link 20 to rotate. Through the slide groove 21, the locking block 22 retracts and disengages from the slot 15 of the trench shovel 3. At this time, the old trench shovel 3 can be directly removed. When installing the new trench shovel 3, it is put into the connecting post 17. After releasing the button 24, the spring 23 pushes the connecting rod 20 to reset, so that the locking block 22 pops into the slot 15 to complete the pre-fixing. Finally, the screw 14 is tightened to achieve thread reinforcement. When tilling, the shovel handle 6 is held to cut the trench shovel 3 into the soil. The slope protection plate 4 guides the soil flow to form a trench. The curved rod 2 structure optimizes the torque transmission. The telescopic locking of the inner rod 1 and the outer tube 5 ensures the stability of operation at different depths.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
