Description

Technical Field

[0001] This utility model belongs to the field of hammer technology, and in particular relates to a hammer with a detachable connection between the hammer head and the hammer handle. Background Technology

[0002] Hammers used for striking are generally divided into two types: those with an integrated hammer head and a separate handle.

[0003] The hammer head and handle of a one-piece hammer are less prone to damage and are more durable, but they are more difficult to manufacture and more expensive.

[0004] Although the hammer head and handle of a split hammer are detachable, the disassembly and assembly process is inconvenient and may even require additional equipment to ensure the stability of the connection between the hammer head and handle.

[0005] Utility model patent CN222177612U discloses a hammer with a detachable hammerhead, which uses a magnetic attraction principle to allow for the replacement of different hammerheads. However, the magnetic attraction component is easily damaged under strong impact. Utility model patent CN222038413U discloses a hammer designed to prevent detachment, which uses a positioning block to securely connect the hammerhead to the handle. However, there are flaws in the direction of force applied during use and the orientation of the positioning block, and the positioning block is also prone to damage after a period of use.

[0006] Therefore, it is necessary to design a hammer that is easy to assemble quickly, has good stability, and improves service life while maintaining a simple structure. Utility Model Content

[0007] This invention provides a hammer to solve the problems mentioned in the background section. It enables rapid assembly between the hammer head and the handle, and the connection between them after assembly is stable and reliable. The structure is simple and easy to operate.

[0008] To solve the above-mentioned technical problems, this utility model provides a hammer, including a hammer head and a hammer handle, wherein one end of the hammer head is provided with a striking head; The hammer head is provided with a limiting member arranged along its axial direction at one end away from the striking head, and the hammer handle is provided with a plug-in hole that is plugged into the limiting member. The connection end between the hammer head and the hammer handle is also provided with a limiting structure to restrict the hammer head or the hammer handle from rotating in the axial direction of the limiting member.

[0009] As a further improvement, the hammer handle is provided with an internal threaded hole that is threaded to the limiting member.

[0010] As a further improvement, the limiting structure includes at least one fitting portion one located on the hammer head near the peripheral surface of the limiting member, and a fitting portion two located on the hammer handle and corresponding to the fitting portion one. After the fitting portion one and the fitting portion two are fitted together, the limiting connection between the hammer head and the hammer handle is realized.

[0011] As a further improvement, the first fitting part is also provided with a groove arranged along the axial direction of the limiting member, and the second fitting part is also provided with a protruding end inserted into the groove.

[0012] As a further improvement, the protruding end is two corresponding protruding plates spaced apart from each other.

[0013] As a further improvement, the raised plate is elastic.

[0014] As a further improvement, one side of the insertion hole is provided with a notch that communicates with the gap between the two protrusions.

[0015] As a further improvement, the hammer handle shown has a nail-starting opening on one side, close to the direction of the hammer head.

[0016] As a further improvement, a magnetic element is provided at the end of the hammer handle away from the hammer head.

[0017] As a further improvement, the hammerhead is provided with a nail groove, and a magnetic suction element is provided in the nail groove.

[0018] The beneficial technical effects of this utility model are as follows: The axial direction of the limiting component is consistent with that of the hammer head, ensuring no deviation in the direction of force during impact and preventing interference with the stability of the limiting component.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. 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 this utility model based on the specific circumstances.

[0024] like Figures 1 to 9 As shown, this utility model provides a hammer, including a hammer head 100 and a hammer handle 200. One end of the hammer head 100 is provided with a striking head 101, and the other end can be provided with a nail puller (also known as a nail puller) or a rounded hammer head or other common tools.

[0025] The improvement in this product is the detachable connection structure between the hammer head 100 and the hammer handle 200, specifically: Example 1 A limiting member 110 is provided at the end of the hammer head 100 away from the striking head 101, arranged along its axial direction (length as shown in the figure). This limiting member 110 can be a cylinder, a triangular prism, or a quadrilateral prism, as shown in the figure. In this embodiment, a cylinder is used as an example. Additionally, the hammer handle 200 is provided with an insertion hole 230 that interlocks with the limiting member 110. This insertion hole 230 can be a through hole (through the width of the hammer handle 200 as shown in the figure) or a blind hole. In this structure, the insertion hole 230 is a through hole, and its diameter needs to match the diameter of the limiting member 110. It cannot be too large or too small; otherwise, there will be slight wobbling or the two cannot be inserted. When the limiting member 110 is placed into the insertion hole 230, the two have a certain degree of connection stability after insertion, ensuring that the hammer head 100 and the hammer handle 200 cannot be displaced in the radial direction, nor can they easily separate or fall off in the axial direction.

[0026] In other words, the hammer head 100 and the hammer handle 200 are connected by the insertion of the limiting member 110 into the insertion hole 230, and the insertion direction is consistent with the axial direction of the hammer head 100, which facilitates assembly. This insertion structure ensures that the direction of force during striking corresponds to the insertion direction, and the limiting member 110 and the insertion hole 230 are not easily subjected to large impact forces, making them less prone to damage and thus improving their overall lifespan. The impact force generated during striking can be dispersed from the hammer head 100 to the hammer handle 200. If the axial direction of the limiting member 110 were to be longitudinally or transversely aligned with the axial direction of the hammer head 100, then the limiting member 110 would be subjected to a larger impact force and be more prone to deformation.

[0027] In this embodiment, to facilitate the individual replacement of the limiting member 110, the hammer handle 200 is provided with an internal threaded hole 111 that is threaded to the limiting member 110. That is, the limiting member 110 and the internal threaded hole 111 are fastened together by thread. When the limiting member 110 is deformed or misaligned, it can be replaced individually without replacing the entire hammer head 100, making it more convenient to use. Of course, the limiting member 110 can also be made as follows... Figure 6 and Figure 8 The internal hex bolt shown is a more convenient and cost-effective option for using universal parts.

[0028] In addition, a limiting structure is provided at the connection end of the hammer head 100 and the hammer handle 200 to restrict the hammer head 100 or the hammer handle 200 from rotating in the axial direction of the limiting member 110. This limiting structure can achieve a better limiting effect after the hammer head 100 and the hammer handle 200 are connected by insertion, and ensure the stability of the connection between the two while being easy to assemble.

[0029] The limiting structure specifically includes at least one first fitting portion 120 located on the circumferential surface of the hammer head 100 near the limiting member 110, and a second fitting portion 210 located on the hammer handle 200 and corresponding to the first fitting portion 120. When the first fitting portion 120 and the second fitting portion 210 are fitted together, the limiting connection between the hammer head 100 and the hammer handle 200 is achieved. After the two fitting portions 120 and 210 are fitted together and close to each other, they can use their surfaces to play a limiting role, forming multiple limiting points, making the insertion of the hammer head 100 and the hammer handle 200 more stable.

[0030] Example 2 The purpose of this embodiment is to provide a structure based on Embodiment 1 to further improve the connection stability between the hammer head 100 and the hammer handle 200.

[0031] like Figure 3 and Figure 4 As shown, in actual use, the striking direction, point of force, and striking force are different, so the insertion method between the hammer head 100 and the hammer handle 200 will be affected to a certain extent, which can easily cause deformation and loosening between the two. In order to ensure stability, the first fitting part 120 is also provided with a groove 121 arranged along the axial direction of the limiting member 110, and the second fitting part 210 is also provided with a protruding end 220 inserted into the groove 121. The protruding end 220 is inserted into the groove 121 to realize a multi-step insertion structure, which can better ensure the stability of the connection. The protruding end 220 is also two corresponding protruding plates spaced apart from each other, and the two protruding plates can be inserted into the groove 121 to realize insertion.

[0032] In addition, further improvements can be made based on this embodiment, such as: the two protruding plates are elastic, and after the two protruding plates are inserted into the groove 121, they can use their own elasticity to apply force to the inner wall of the groove 121, thereby improving the stability of the insertion and making it less likely for them to separate and fall off.

[0033] As a further improvement, one side of the insertion hole 230 is provided with a notch 231 that communicates with the gap 221 between the two protruding plates. The two protruding plates are respectively located on both sides of the notch 231, so that the two protruding plates are more likely to move closer or further apart, the elasticity between the protruding plates is greater, and it is easier to insert into the groove 121.

[0034] As a further improvement, the hammer handle 200 shown has a nail-picking opening 203 on one side, close to the hammer head 100, so that the hammer handle 200 alone can perform nail-picking operations even without the hammer head 100. Of course, an internal hexagonal hole can also be provided on the hammer handle 200 to facilitate the tightening of nuts or bolts.

[0035] To facilitate the handling of workpieces, a magnetic element 201 (such as a magnet) is provided at the end of the hammer handle 200 away from the hammer head 100. Workers can use the bottom end of the hammer handle 200 to approach the workpiece and attract it under the action of magnetism without having to bend over or squat down significantly.

[0036] To facilitate nailing, the hammer head 100 is provided with a nail groove 102. As shown in the figure, the nail groove 102 is located on one side of the hammer head 100. A magnetic attractor 103 (such as a magnet) is provided in the nail groove 102. The nail can be placed into the nail groove 102 and fixed by magnetic attraction, which allows for one-handed operation when nailing, making it more convenient.

[0037] When the limiting member 110 in this utility model is fixedly connected to the hammer head 100, the hammer handle 200 can be as follows: Figure 8 The angle and direction shown are for insertion into the hammer head 100, i.e., the insertion hole 230 and the limiting member 110 are mutually inserted. If the limiting member 110 is detachably connected to the hammer head 100, the hammer handle can be... Figure 8 The angle and direction shown are used to connect the hammer head 100. Alternatively, the protruding end 220 can be connected to the groove 121 first from bottom to top, and then the insertion hole 230 can be connected to the limiting member 110 step by step.

[0038] The beneficial technical effects of this utility model are as follows: The axial direction of the limiting component is consistent with that of the hammer head, ensuring no deviation in the direction of force during impact and preventing interference with the stability of the limiting component. Inserting the limiting component into the insertion hole allows for rapid assembly of the hammer head and handle. Furthermore, the limiting structure further restricts the movement between the hammer head and handle, preventing misalignment and enhancing connection stability.

[0039] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
