Description

Technical Field

[0001] This utility model relates to the field of claw hammer technology, and in particular to a novel claw hammer. Background Technology

[0002] Traditional claw hammers typically feature a fixed claw design. While this meets functional requirements such as nail removal, the protruding claw can easily snag on other objects or injure the user during transport or storage. Furthermore, the sharp points of the claw can cause cuts or punctures to the user or those nearby due to improper handling. While claw hammer designs with retractable claws exist, the complex storage structure increases manufacturing difficulty, and the intricate design significantly impacts the strength of the connecting ends.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a new type of claw hammer to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and for the convenience of those skilled in the art to understand it. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the present invention discloses a new type of claw hammer, which reduces the possibility of injury to personnel from the claw during use and storage through a retractable claw design.

[0006] This utility model discloses a novel claw hammer, including a hammer head and a hammer handle fixedly connected to the hammer head. One end of the hammer head has a striking surface, and the other end has a claw portion. The claw portion is rotatably connected to the hammer head by a pin, allowing the claw portion to rotate around the axis of the pin between a retracted position close to the hammer handle and a working position away from the hammer handle. A limiting structure is fixedly provided on the hammer head, located at the end of the movement path when the claw portion rotates to the working position, to prevent the claw portion from continuing to rotate away from the hammer handle. A limiting protrusion is fixedly provided on the pin along its axial direction. A first groove matching the limiting protrusion is provided on the side of the claw portion. When the claw portion rotates to the working position, the pin can move along its axial direction, causing the limiting protrusion to engage in the first groove, thereby locking the circumferential rotation of the claw portion and ensuring that the claw portion will not accidentally rotate during operation.

[0007] Preferred technical solution: The side of the ram's horn is also provided with a second groove that matches the limiting protrusion. The second groove is intersected with the first groove. When the ram's horn is flipped to the storage position, the pin can move along its axial direction, so that the limiting protrusion is engaged in the second groove, thereby locking the circumferential rotation of the ram's horn and ensuring that the ram's horn will not flip over accidentally in the storage state.

[0008] Preferred technical solution: The hammer head is also provided with a detachable pressure cap. The pressure cap is located on the side away from the connection surface between the hammer head and the horn. The pressure cap has a contoured groove that mates with the pin and the limiting protrusion to prevent the pin from rotating circumferentially and enhance the stability of the locking structure.

[0009] Preferred technical solution: The limiting structure consists of a limiting block and a limiting groove on the hammer head. When the horn is flipped to the working position, the root of the horn abuts against the limiting block and the limiting groove to ensure its stability during use.

[0010] Preferred technical solution: The two ends of the pin are axially movable and installed in the shaft hole of the hammer head. The two ends of the pin are provided with an operating part and an elastic reset part. The elastic reset part provides an axial preload force that tends to make the limiting protrusion automatically engage with the first groove and the second groove, which simplifies the operation steps of switching the position of the hammer head.

[0011] Preferred technical solution: A nail box is provided on the side of the hammer handle near the hammer head. The nail box is detachably connected to the hammer handle by magnetic attraction, which facilitates the storage and retrieval of nails.

[0012] Preferred technical solution: The nail box is equipped with a flip-up magnetic lid for easy storage and retrieval of nails.

[0013] Preferred technical solution: The hammer handle has a cylindrical structure and a flip cover at the tail end. The flip cover is connected to the hammer handle by an elastic buckle and can be used to store small tools or spare parts.

[0014] Preferred technical solution: The striking surface is covered with a removable silicone sleeve to reduce vibration and noise during striking, while also reducing the possibility of damage to the surface of the object being struck.

[0015] Preferred technical solution: The hammer head and hammer handle are forged as a single piece, which improves the strength and durability of the overall structure.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0017] 1) With its flip-up ram's horn design, the ram's horn can be placed close to the hammer handle when stored, significantly reducing the risk of injury to people from the ram's horn when carrying or storing it.

[0018] 2) The locking mechanism of the limiting protrusion and the groove is adopted to ensure that the ram's horn can be firmly fixed in both the working position and the storage position, and to prevent accidental flipping.

[0019] 3) The design of the elastic reset component simplifies the operation steps and improves the user experience;

[0020] 4) Additional features such as nail box and silicone sleeve further enhance the functionality of the claw hammer. Attached Figure Description

[0035] Example:

[0036] like Figure 1 As shown, this utility model discloses a novel claw hammer, including a hammer head 1 and a hammer handle 2. The hammer head 1 and the hammer handle 2 are integrally forged. The main components of the present utility model will be described in detail below:

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one end of the hammer head 1 has a striking surface 11 covered with a removable silicone sleeve 7; the other end has a horn portion 3, which is rotatably connected to the hammer head 1 via a pin 4. The striking surface 11 and the horn portion 3 are arranged opposite each other at 180°, allowing the horn portion 3 to rotate around the axis of the pin 4 between a storage position close to the hammer handle 2 and a working position away from the hammer handle 2. A limiting structure 12 is fixedly provided on the hammer head 1. The limiting structure 12 is located at the end of the movement path of the horn portion 3 when it rotates to the working position, and is used to prevent the horn portion 3 from continuing to rotate away from the hammer handle 2. A limiting protrusion 41 is fixedly provided on the pin 4 along its axial direction. A first groove 31 matching the limiting protrusion 41 is provided on the side of the horn portion 3. When the horn portion 3 rotates to the working position, the pin 4 can move along its axial direction, so that the limiting protrusion 41 is engaged in the first groove 31, thereby locking the circumferential rotation of the horn portion 3. The side of the horn portion 3 is also provided with a limiting protrusion 41 matching the limiting protrusion 41. The second groove 32 matches the first groove 31 and is intersected with it. When the ram's horn 3 is flipped to the storage position, the pin 4 can move along its axial direction, causing the limiting protrusion 41 to engage in the second groove 32, thereby locking the circumferential rotation of the ram's horn 3. The hammer head 1 is also detachably provided with a pressure cap 5, which is located on the side away from the connection surface between the ram's horn 3 and the hammer head 1. The pressure cap 5 has a contoured slot that mates with the pin 4 and the limiting protrusion 41. The limit structure 12 is a limit block and a limit groove provided on the hammer head 1. When the horn part 3 is flipped to the working position, the root of the horn part 3 abuts against the limit block and the limit groove. The two ends of the pin 4 are axially movable in the shaft hole of the hammer head 1, and the two ends of the pin 4 are provided with an operating part and an elastic reset member. The elastic reset member provides an axial preload force that tends to make the limit protrusion 41 automatically engage with the first groove 31 and the second groove 32.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a nail box 6 is provided on the side of the hammer handle 2 near the hammer head 1. The nail box 6 is detachably connected to the hammer handle 2 by magnetic attraction. The nail box 6 is provided with a flip-up magnetic cover. The hammer handle 2 has a cylindrical structure and a flip cover 21 at the tail end. The flip cover 21 is connected to the hammer handle 2 by an elastic buckle.

[0039] The method of use and principle of this utility model are as follows:

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, switch from the storage location to the work location:

[0041] Press the operating part of the pin 4 to overcome the elastic force of the elastic reset member and make the limiting protrusion 41 disengage from the second groove 32;

[0042] Flip the ram's horn 3 outward to the working position until its base abuts against the limiting structure 12;

[0043] Release the operating part, and the elastic reset member pushes the pin 4 to move axially, so that the limiting protrusion 41 is engaged in the first groove 31 to complete the locking. At this time, the horn part 3 can be used normally.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, switch from the work position to the storage position:

[0045] Press the operating part of the pin 4 to disengage the limiting protrusion 41 from the first groove 31;

[0046] Flip the ram's horn 3 inwards to the storage position close to the hammer handle 2;

[0047] Release the operating part, and the limiting protrusion 41 will engage with the second groove 32 to complete the locking. At this time, the ram's horn 3 will be retracted, reducing the size of the hammer head 1 and preventing the ram's horn 3 from causing injury to the user when using the striking surface 11.

[0048] This invention solves the safety issues of traditional claw hammers through its innovative reversible claw design and double locking mechanism. Simultaneously, its integrated multiple practical functions significantly enhance the tool's usability. With its reasonable structure, simple operation, and reliable performance, it is suitable for various scenarios such as home use, construction, and decoration, and has broad market prospects.

[0049] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
