Description

Technical Field

[0001] This invention relates to the field of household tools, specifically a chopping tool. Background Technology

[0002] In existing technologies, splitting objects such as wood and ice is usually done using traditional axes or chisels. When using an axe to chop, a large swinging space is required, which demands a high level of skill and strength from the operator. If the strength is insufficient, the axe can easily get stuck in the object being chopped and is difficult to remove. It also poses certain safety hazards, as it can easily lead to accidental injury due to inaccurate chopping or the target object slipping. To address these issues, handheld impact splitting tools have emerged. These typically consist of a splitting head fixed to the object and a weight that slides along a guide rod. By lifting the weight and striking downwards, the force is transferred to the splitting head, allowing for a safer and less strenuous splitting of the object. However, these tools still have some drawbacks: 1) The intermediate moving sleeve gravity hammer does not have a dedicated handle, making it inconvenient to hold and operate. 2) The direction of the chopping head is prone to change when chopping objects. Moving the chopping tool between chopping objects is extremely inconvenient. One must release one hand to hold the exposed guide rod on the sleeve, and the other hand to grip the steel pipe on the gravity sleeve hammer. Both hands must work together to move the tool, making it very inconvenient and difficult to operate. 4) Current chopping tools lack a limit and anti-detachment device on the guide rod. If the operator lifts the gravity sleeve too high, the guide rod can easily slip off the sleeve and onto the gravity hammer, posing a significant risk of injury. Therefore, there is an urgent need for a well-designed, safe, labor-saving, and easily portable tool for chopping objects. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a chopping tool, including a chopping head and a guide rod connected to the chopping head, the guide rod being sleeved with a movable sleeve, the bottom of the movable sleeve being provided with a hammer head for striking the end of the chopping head, and the end of the movable sleeve away from the hammer head being connected to two handles; the handles of the movable sleeve being provided with two through holes; the guide rod being provided with a positioning hole, the top of the guide rod being provided with two anti-disengagement limiting screws, and the handles or the movable sleeve being provided with a locking structure for locking the guide rod with the positioning hole. Preferably, the locking structure is disposed inside the handle, the positioning holes are disposed on both sides of the guide rod, the handle includes a first handle section connected to both sides of the movable sleeve, the first handle section is detachably connected to a second handle section by threads, the other end of the second handle section is sleeved with a first button, the locking structure includes a screw fixed inside the first button, the end of the screw away from the first button is threadedly connected to a first locking rod and a cylindrical guide rod that can be inserted into the positioning hole, a limit ring is provided at the connection between the first locking rod and the cylindrical guide rod, a support limiting plate is provided inside the second handle section that abuts against the limit ring, the support limiting plate is close to the thread of the second handle section, and a first return spring is provided between the support limiting plate and the inner wall of the first button. Preferably, the capped screw is connected and fixed to the nut inside the first button and the first button. Preferably, the locking structure is disposed on the movable sleeve and located between the handles; the positioning hole is located on the side of the guide rod and corresponds to the locking structure; the through hole on the movable sleeve corresponds to the locking structure; the locking structure includes a locking base disposed on the side of the movable sleeve and a second button slidably disposed within the locking base; a second locking rod that can be inserted into the positioning hole is fixedly disposed within the second button; the diameter of the round head of the second locking rod near the positioning hole of the guide rod is larger than the diameter of the body of the second locking rod; the end of the second locking rod away from the positioning hole is provided with a threaded hole, which is connected to a fixing screw disposed on the end of the second button; a second return spring is disposed between the second button and the inner bottom surface of the locking base. Preferably, the inner bottom surface of the locking base is provided with a guide hole that fits onto the outside of the second locking rod. Preferably, the guide rod is a polygonal guide rod with a polygonal cross-section, the inner cavity of the movable sleeve is a circular inner cavity, and the inner cavity of the hammer head is provided with a circular inner cavity and a polygonal inner cavity that conforms to the shape of the guide rod. Preferably, the bottom of the splitting head is a sharp end, and the top is provided with a force-bearing plate to receive the hammer head. Preferably, when the locking structure is disposed on the movable sleeve and located between the handles, the handle is a straight handle or a curved handle. The advantages of this invention compared to the prior art are: (1) By setting a unique locking structure, the user can easily switch between the "working state" and the "carrying state". In the working state, the locking structure is in the normally unlocked state, and the moving sleeve and the hammer head can slide freely along the guide rod to impact and split objects; in the carrying state, the locking structure locks the moving sleeve to the positioning hole on the guide rod, making the entire tool a rigid whole with a fixed length, which greatly facilitates hand-carrying and storage. (2) In the embodiment of the present invention, the locking structure is set inside the handle. Through the threaded connection design, the second section of the handle and the locking structure can be disassembled from the first section of the handle, which further shortens the lateral dimension of the tool and makes it easier to put into a bag or store in a small space. (3) The guide rod of the present invention adopts a polygonal prismatic tube design, and the inner cavity of the hammer head is provided with a polygonal guide hole that is compatible with it, ensuring that the moving sleeve will not rotate relative to each other during the sliding process, so that the hammering force is accurately and vertically applied to the force plate of the splitting head, thereby improving the splitting efficiency and operational stability. (4) The present invention provides two preferred locking structure implementation schemes. Scheme 1 places the locking structure inside the handle, which is simple and reliable to operate. Scheme 2 places the locking structure on the movable sleeve between the two handles. This invention utilizes the principle of gravity impact, making it more labor-saving and safer than traditional axe chopping, thus reducing the physical demands on the operator. Furthermore, because it eliminates the need for large swings, it requires less workspace, significantly improving operational safety.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances. Example 1: Based on the implementation of claims 1-3 and 6-7 refer to Figure 1-5 This embodiment provides a splitting tool, mainly used for splitting objects such as wood and ice. The splitting tool includes a splitting head 1, a guide rod 2, a movable sleeve 3, a hammer head 4, and a handle 5. The bottom of the splitting head 1 is a sharp end 11, which facilitates cutting into the object to be split. A force-bearing plate 12 is fixedly connected to the top of the splitting head 1. One end of the guide rod 2 is fixedly connected to the center of the force-bearing plate 12. The cross-section of the guide rod 2 is preferably a regular hexagon or a square polygonal structure. The movable sleeve 3 is fitted onto the outside of the guide rod 2. The movable sleeve 3 has a hollow circular through hole inside, and the hammer head 4 is fixedly installed at the bottom of the movable sleeve 3. The hammer head 4 has a circular hole and a polygonal hole 8 near the bottom inside. The diameter of the circular hole is larger than the length of opposite sides of the polygonal hole 8. The shape of the polygonal hole 8 is adapted to the polygonal cross-section of the guide rod 2. This allows the hammer head 4 to move axially along the guide rod 2 while both hands hold the handle 5 and move the movable sleeve 3, without the guide rod rotating relative to it, and the chopping head 1 below the guide rod 2 will not rotate relative to it. When the user holds the handle 5, lifts the movable sleeve 3 upward, and then strikes it downward, the hammer head 4 will hit the force plate 12 at the top of the chopping head 1, thereby wedging the chopping head 1 deeper into the object. Two anti-disengagement limiting screws 10 are provided at the top of the guide rod 2. The handle 5 is connected to the end of the movable sleeve 3 away from the hammer head 4. In this embodiment, the locking structure 6 is disposed inside the handle 5. Specifically, a series of positioning holes 21 are symmetrically opened on both sides of the end of the guide rod 2 away from the splitting head 1. A through hole 301 is opened at the connection between the movable sleeve 3 and the first section 51 of the handle. The handle 5 includes a first handle section 51 fixedly connected to both ends of the movable sleeve 3. A second handle section 52 is detachably connected to the first handle section 51 via threads. A first button 53 is sleeved on the other end of the second handle section 52, and the first button 53 can slide axially relative to the second handle section 52 to a certain extent. The locking structure 6 includes a nut-loaded screw 61 disposed within the handle 5. The nut end of the screw 61 and the nut 62 are locked together with the first button 53. The end of the screw 61 away from the first button 53 extends into the circular hole of the support limiting plate 65 inside the second section 52 of the handle, and is threadedly connected to a first locking rod 63 and a cylindrical guide rod 9 with internal threads. The end of the first locking rod 63 away from the screw 61 can be inserted into the through hole 301 on the movable sleeve 3 and the positioning hole 21 on the side of the guide rod 2. A limiting ring 64 is provided between the first locking rod 63 and the cylindrical guide rod 9. A support limiting plate 65 is fixedly disposed on the inner wall of the second section 52 of the handle near the thread, and the first locking rod 63 and the limiting ring 64 are located between the support limiting plate 65 and the through hole 301 on the movable sleeve 3. A first return spring 66 is sleeved on the screw 61 between the support limiting plate 65 and the inner wall of the first button 53. Working principle: When chopping objects, the user simply holds the handle 5 with both hands, lifts the movable sleeve 3 upwards, and then quickly presses the handle 5 downwards. The movable sleeve 3, along with the hammer head 4, strikes the force plate 12 on the chopping head 1 to perform the chopping operation. When both hands hold the handle 5, the first button 53, without external force, will be in the extended return spring 66 state. This will cause the first button 53 to move outwards along the second section 52 of the handle. The outward movement of the first button 53 will cause the screw 61 and the first locking rod 63 to disengage from the positioning hole 21 on the guide rod 2. At this time, holding the handle 5 with both hands allows the movable sleeve 3 to slide up and down along the guide rod 2 for chopping operations. When it is necessary to lock the chopping tool while moving it to another location, press the first button 53 with one hand. Pressing the first button 53 will cause the screw 61 and the first locking rod 63 to push into the positioning hole 21, thus locking the tool. By disassembling the connecting threads between the first section 51 and the second section 52 of the handle, the second section 52 of the handle can be easily removed from the first section 51 of the handle, which facilitates the production and installation of the locking structure 6 and saves more packaging space for packaging and transportation. Example 2: Implementation based on claims 1, 4-8 refer to Figure 6-7 The core components (splitter head 1, guide rod 2, moving sleeve 3, hammer head 4) of this embodiment are basically the same as those of Embodiment 1. The main difference lies in the setting position and specific structure of the locking structure 6. In this embodiment, the handle 5 is fixed to the movable sleeve 3 by the first handle section 51 and the second handle section 52. The handle 5 is not limited to any particular shape, such as whether it is curved or ring-shaped. The function of the handle 5 is to be used to grip and operate the movable sleeve 3. The locking structure 6 is directly mounted on the side wall of the movable sleeve 3 and located between the two handles 5. A series of positioning holes 21 corresponding to the locking structure 6 are provided on the side of the guide rod 2. The locking structure 6 includes a locking base 67 fixed to the side wall of the movable sleeve 3. A second button 68 is slidably mounted inside the locking base 67. The second button 68 has a screw hole at its top and a second locking rod 69 inside. One end of the second locking rod 69 has a round head slightly larger than its own diameter, and the other end has a fixing threaded hole. The round head end of the second locking rod 69 can be inserted into the positioning hole 21 on the side of the guide rod 2. The diameter of the round head end of the second locking rod 69 is larger than the diameter of the guide hole 72 on the locking base 67, and the diameter of the rod body is larger than the diameter of the screw hole on the second button 68. The other end of the second locking rod 69 has a fixing threaded hole. A fixing bolt 70 is inserted from the screw hole at the end of the second button 68 and connected and fixed to the fixing threaded hole at one end of the second locking rod 69. A second return spring 71 is provided between the inner bottom surface of the second button 68 and the inner bottom surface of the locking base 67. The second locking rod 69 is placed in the middle of the return spring 71. In order to ensure that the second locking rod 69 moves smoothly, a guide hole 72 is also fixedly provided on the inner bottom surface of the locking base 67, and the rod body of the second locking rod 69 moves axially in the guide hole 72. Working principle: Due to the second return spring, the second locking rod 69 is normally in a released and disengaged state from the positioning hole 21 on the guide rod 2, allowing the operator to hold the handle 5 with both hands for chopping operations. When the operator needs to move the chopping tool and lock the guide rod 21, the operator only needs to press the second button 68 with one thumb of the hand holding the handle 5. The second button 68 pushes the second locking rod 69 into the positioning hole 21 to lock the guide rod 2.
