[0023] like Figures 1 to 3 As shown, a specific embodiment of the present invention provides a novel multifunctional claw hammer, comprising a hammer head 1 and a first hammer handle 2, the hammer head 1 and the first hammer handle 2 are fixedly arranged, a claw assembly 3 is fixedly arranged on one side of the hammer head 1, a shock-absorbing assembly is arranged inside the hammer head 1, the shock-absorbing assembly includes a spring 7 and a steel ball 8, at least two groups of steel balls 8 are provided, and the steel ball 8 is fitted with one side of the spring 7, a second hammer handle 9 is provided at the lower end of the first hammer handle 2, a mounting rod 10 is provided at the upper end of the second hammer handle 9, a screwdriver head 14 is provided at the upper end of the mounting rod 10, the screwdriver head 14 is provided in several groups and each group can be installed inside the mounting rod 10, a wrench assembly is provided at the lower end of the second hammer handle 9, the wrench assembly includes a first jaw 16 fixedly arranged at the lower end of the second hammer handle 9 and a second jaw 17 slidably arranged at the lower end of the second hammer handle 9.

[0024] By adopting the above technical solution, the utility model is designed with a shock-absorbing component, which uses the inertia of the steel ball 8 during the striking process to offset part of the rebound force to achieve the purpose of reducing vibration, so that the claw hammer has a shock-absorbing function. By designing a wrench component at the lower end of the second hammer handle 9 and installing it integrally with the first hammer handle 2, the claw hammer has the function of removing nuts. Further, after the second hammer handle 9 is removed, the screwdriver head 14 is installed on the upper part, and the second hammer handle 9 can be used as a screwdriver to remove screws, thereby further improving the functionality of the claw hammer.

[0025] Specifically, such as Figure 2 As shown, a slide groove 20 is provided at the lower end of the second hammer handle 9 , the size of the slide groove 20 is adapted to the slide rod 18 , the slide rod 18 is slidably set inside the slide groove 20 , and the lower end of the slide rod 18 is fixed to the second jaw 17 .

[0026] By adopting the above technical solution, the distance between the first jaw 16 and the second jaw 17 is adjusted by moving the sliding rod 18 inside the sliding groove 20 so that it can adapt to the removal of nuts of various sizes. The first jaw 16 and the second jaw 17 are installed at the lower part of the second hammer handle 9 and are integrated into the first hammer handle 2, so that the claw hammer has the function of removing nuts, thereby improving the versatility of the claw hammer.

[0027] Specifically, such as Figure 3 As shown, a worm 21 is rotatably provided on one side of the second hammer handle 9 , and a plurality of groups of evenly arranged convex teeth 19 are fixedly provided on the outer side of the slide bar 18 , and the convex teeth 19 are meshed with the worm 21 .

[0028] By adopting the above technical solution, the convex tooth 19 is meshed with the worm 21. During the rotation of the worm 21, it adheres to the side wall of the convex tooth 19 and pushes the convex tooth 19 and the sliding rod 18 to move as a whole, thereby achieving the purpose of adjusting the distance between the first jaw 16 and the second jaw 17.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, the sizes of the blade ends of the screwdriver head 14 are all different. The screwdriver head 14 is made of a high-strength metal material and is magnetic. The other end of the screwdriver head 14 is consistent in size and is not limited to a hexagon. The screwdriver head 14 can be set inside the first mounting groove 11 and the second mounting groove 15. The first mounting groove 11 is set inside the mounting rod 10, and the second mounting groove 15 is set inside the second hammer handle 9. The screwdriver head 14 can be set inside the first mounting groove 11 and the second mounting groove 15 by magnetic attraction.

[0030] By adopting the above technical solution, the sizes of the blade ends of the screwdriver head 14 are different, so that it can adapt to the disassembly and installation of screws of more sizes. The screwdriver head 14 is magnetic, which makes it easy to be installed inside the first installation groove 11. On the other hand, after use, it can be stored in the second installation groove 15 to prevent it from falling off and being lost.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, the lower end of the mounting rod 10 is fixed to the second hammer handle 9. The size of the mounting rod 10 is adapted to the storage cavity 13 and is arranged inside the storage cavity 13. The storage cavity 13 is arranged inside the first hammer handle 2. A threaded layer 12 is provided on the outer side of the lower end of the mounting rod 10, and the mounting rod 10 is connected to the storage cavity 13 by threads.

[0032] By adopting the above technical solution, after the second hammer handle 9 is removed, the screwdriver head 14 can be installed in the inside of the first mounting groove 11 to use it as a screwdriver, further increasing the versatility of the claw hammer. The mounting rod 10 is connected to the storage cavity 13 by a thread, which facilitates the second hammer handle 9 to be quickly removed from the first hammer handle 2 and quickly installed with the first hammer handle 2 after use.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, a movable cavity 6 is provided inside the hammer head 1, and several groups of steel balls 8 are slidingly provided inside the movable cavity 6. The steel balls 8 are all provided at one end close to the horn component 3. A spring 7 is provided inside the movable cavity 6, and the spring 7 is provided at one end away from the horn component 3.

[0034] By adopting the above technical solution, the hammer head 1 will generate rebound force and vibration when hitting the nail. When the hammer head 1 no longer moves toward the nail after contacting the nail, the steel ball 8 will continue to move due to inertia to offset the rebound force to achieve the effect of reducing vibration, and the feeling of vibration transmitted to the hand is reduced, which improves the comfort during use. The contact area between the steel ball 8 and the movable cavity 6 is small, and the friction force generated during its movement is small, which has little effect on the inertia, so that the inertia can better offset the rebound force. The inertia of the steel ball 8 is transmitted to the hammer head 1 through the compression spring 7 to offset the rebound force. The spring 7 also has the function of restoring the steel ball 8 to its original position.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, a nail groove 4 is provided at the upper end of the hammer head 1 , and a magnetic block 5 is provided at the bottom of the nail groove 4 .

[0036] By adopting the above technical solution, the nail is placed in the nail groove 4 and fixed by the magnetic block 5. The nail can be directly hammered into the required position without the need to support the nail with hands to maintain the stability of the nail, thereby reducing the occurrence of hand injuries.

[0037] Specifically, such as Figure 1 As shown, a handle sleeve 22 is provided on the outer side of the first hammer handle 2 , and a hanging hole 23 is provided on one side of the first hammer handle 2 .

[0038] By adopting the above technical solution, the handle sleeve 22 can increase the friction between the handle sleeve and the palm, thereby making the claw hammer more firmly gripped during use, and also improving the comfort when using the claw hammer. When working at height, the hanging hole 23 connects the claw hammer to the rope body to prevent it from detaching and falling.

[0039] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may 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 detail for the sake of simplicity.

[0040] The present invention 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 the present invention shall be included in the scope of protection of the present invention.
