Description

Technical Field

[0001] This utility model relates to the field of claw hammers, specifically a multifunctional integrated claw hammer. Background Technology

[0002] A claw hammer is a common hand tool, mainly composed of a hammerhead and a handle. The hammerhead is usually made of metal, with one end flattened for striking objects, such as nails, using its flat surface to drive the nail vertically into the object; the other end is designed in the shape of a ram's horn, hence its name. The horn part has a unique function: when pulling out nails, the horn is used to wedge the nail, and then, through leverage, force is applied with the handle to easily pull the nail out. The claw hammer has a simple structure but is highly practical, and is widely used in construction, decoration, carpentry, and many other fields.

[0003] In the current tool market, existing claw hammers have significant design shortcomings. Most of them use a fixed claw design. When faced with nails of different sizes and embedment depths, the fixed claw makes it difficult to adjust the angle and position flexibly, and it cannot accurately fit the nail, making nail removal difficult. Moreover, in some narrow or special angled spaces, the fixed claw cannot adapt to the environment, which greatly limits the scope of use of claw hammers and cannot fully meet diverse work needs. There is still room for improvement in the structure. Utility Model Content

[0006] Preferably, the ram's horn includes a connector, the top of which is fixedly connected to the ram's horn body, and a through toothed groove is formed inside the lower part of the connector.

[0007] Preferably, the rotatable connection between the hammer handle and the ram's horn is achieved by the rotation of the actuating teeth within the tooth groove.

[0008] Preferably, the top of the metal handle has an arc-shaped design, and the bottom of the ram's horn body has a corresponding arc-shaped design.

[0009] Preferably, the lower section of the metal handle has an I-shaped structure.

[0018] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-functional integrated claw hammer, including a handle 1, with a claw 2 rotatably connected to the top of the handle 1, and the claw 2 is designed to be rotatable.

[0020] This claw hammer features an ingenious design, with its core highlight being the claw's flexible, freely rotating nature. Users can easily adjust the orientation of the claw 2 according to actual usage scenarios, such as pulling nails, prying objects, or adjusting the angle of force. It can meet diverse needs without changing tools. The rotating structure is precisely designed to ensure that the claw 2 rotates stably and smoothly, while the locking mechanism is reliable. It can quickly switch modes and is firmly positioned after the selected angle to prevent accidental deviation during operation. This innovative design greatly improves the tool's applicability and operating efficiency, allowing users to handle woodworking, repair, or disassembly and assembly tasks with ease, truly achieving the convenient experience of "one hammer for multiple uses".

[0021] The hammer handle 1 includes a metal handle 11. A rubber anti-slip sleeve 12 is fitted on the outer side of the top of the metal handle 11. A hammer head 13 is fixedly connected to the front side of the top of the metal handle 11. The top of the metal handle 11 is designed to be open. A prying tooth 15 is rotatably connected to the inner wall of one side of the top of the metal handle 11. An opening is opened on the other side of the top of the metal handle 11. A fastening bolt 14 is threadedly connected to the opening.

[0022] The lower section of the metal handle 11 has an I-shaped structure;

[0023] In practical applications, the I-shaped structure of the metal handle 11 provides strong support and can withstand external forces steadily. At the same time, this ingenious design effectively reduces the overall weight while ensuring support, making it easier and more convenient for users to hold. Meanwhile, the use of the rubber anti-slip sleeve 12 increases the friction when holding the handle, which can effectively reduce the occurrence of slipping even when hands are sweaty or in a relatively slippery environment, further improving the safety and comfort of use.

[0024] The ram horn 2 includes a connector 21, the top of which is fixedly connected to the ram horn body 22, and a through toothed groove 23 is opened inside the lower part of the connector 21;

[0025] The rotational connection between the hammer handle 1 and the ram's horn 2 is achieved by rotating the tooth 15 within the tooth groove 23.

[0026] In actual operation, when it is necessary to adjust the angle of the horn 2 according to specific needs, first loosen the fastening bolt 14. This operation is to release the fixed constraint on the moving tooth 15 and make the horn 2 have the possibility of adjusting the angle.

[0027] The ram horn 2 is able to adjust its angle thanks to its unique structural design, namely the clever cooperation between the tooth groove 23 and the actuating tooth 15. After the fastening bolt 14 is loosened, the user can easily adjust the ram horn 2 to the desired angle position by rotating it, so that the actuating tooth 15 can rotate within the tooth groove 23.

[0028] Once the ram horn 2 is adjusted to the ideal position, the fastening bolt 14 should be tightened. During the tightening process, the fastening bolt 14 will press against the connecting piece 21. This pressing and fixing method can effectively lock the ram horn 2 in the current position, preventing the ram horn 2 from continuing to rotate and shaking due to vibration or other external forces during subsequent use, thus ensuring the stability and reliability of the equipment operation.

[0029] The top of the metal handle 11 has an arc-shaped design, and the bottom of the ram's horn body 22 has a corresponding arc-shaped design;

[0030] The curved design prevents the ram horns 2 from interfering with each other during rotation.

[0031] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention includes the claims being limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0032] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
