[0002] A hand hammer, also known as a water hammer, is an indispensable tool for electricians and other repairmen. It is used for straightening, chiseling, repairing, and assembling / removing parts. Experience has shown that improper use of a hand hammer can lead to personal injury, and in severe cases, even fires or explosions. A hand hammer mainly consists of a hammerhead, a wooden handle, and a wedge.

[0003] An adjustable hand hammer, with the existing patent publication number "CN208375216U", includes a hammer body, which comprises a handle and a connecting block. One end of the handle is provided with a bottom cover, an external thread, and a wrench. The bottom cover has a groove with an internal thread, and the bottom cover is installed at the bottom of the handle through the mutual engagement of the internal and external threads. One side of the handle is provided with a first finger sleeve, and the other side of the handle is provided with a second finger sleeve. The connecting block is connected to the handle by a shock-absorbing spring. One side of the connecting block is provided with a frame, and the other end of the connecting block is provided with a second hammer head. The frame has a slot, and the slot contains the first hammer head and a rotating shaft. This adjustable hand hammer has a novel design, high safety, and multiple functions.

[0004] However, in some forging operations, various cones with different counterweights are needed to forge steel plates. This device cannot adjust the weight of the hammer head well, and therefore cannot be used in different forging environments during the forging process. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable force hammer with a detachable counterweight to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable force hammer with detachable counterweights, comprising a handle, a first threaded rod at the top of the handle, an internal threaded tube on the outer side of the first threaded rod, an outer sleeve rod at the top of the first threaded rod, a hammer head on the outer side of the outer sleeve rod, a second threaded rod inside the outer sleeve rod, a rotating plate at the top of the second threaded rod, a counterweight chamber at the top of the outer side of the first threaded rod, and multiple sets of counterweights evenly distributed on the outer side of the first threaded rod, the counterweights being located on the outer side of the first threaded rod.

[0007] Preferably, the bottom of the outer side of the grip is provided with an anti-slip grip, and the outer side of the anti-slip grip is provided with anti-slip texture to improve the grip on the hammer.

[0008] Preferably, the counterweight has a slot on one side, and the slot is compatible with the first threaded rod, so that the counterweight can be easily snapped into the outside of the first threaded rod for assembly.

[0009] Preferably, the inner side of the outer sleeve rod is provided with threads, and the second threaded rod is compatible with the threads for easy connection.

[0010] Preferably, the top of the mallet head is provided with a connecting hole, and the outer sleeve is located inside the connecting hole to facilitate assembly of the mallet head.

[0011] Preferably, the outer side of the internally threaded tube is provided with an anti-slip sleeve to prevent slippage during the rotation of the internally threaded tube.

[0012] Preferably, the top and bottom of the outer side of the internally threaded tube are symmetrically provided with limiting plates to press the counterweight and compact the counterweight during the assembly process.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the adjustable force hammer with detachable counterweight;

[0014] With the cooperation of the internal threaded tube, the first threaded rod, the counterweight chamber, and the counterweight block, the counterweight of the hammer can be adjusted according to the environment of use, so that there is no need to use multiple hammers during operation, thereby reducing the cost of operation. Then, with the cooperation of the second threaded rod, the rotating plate, and the outer sleeve rod, the hammer head can be quickly replaced when it is damaged, thereby reducing the difficulty of replacement.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 The present invention provides an embodiment of an adjustable force hammer with a detachable counterweight, comprising a handle 1, an anti-slip grip on the bottom outer side of the handle 1, and an anti-slip texture on the outer side of the anti-slip grip to improve the grip on the hammer; a first threaded rod 3 on the top of the handle 1, an internally threaded tube 2 on the outer side of the first threaded rod 3, and an anti-slip sleeve on the outer side of the internally threaded tube 2 to prevent slippage during rotation of the internally threaded tube 2; an outer sleeve 7 on the top of the first threaded rod 3; a connecting hole on the top of the hammer head 4; the outer sleeve 7 located inside the connecting hole for assembly of the hammer head 4; and the hammer head 4 on the outer side of the outer sleeve 7. The inner part is provided with a second threaded rod 5, and the inner side of the outer rod 7 is provided with threads. The second threaded rod 5 and the threads are compatible with each other for easy connection. The top of the second threaded rod 5 is provided with a rotating plate 6. The top of the outer side of the first threaded rod 3 is provided with a counterweight chamber 8. Multiple sets of counterweight blocks 9 are evenly provided on the outer side of the first threaded rod 3. The top and bottom of the outer side of the inner threaded tube 2 are symmetrically provided with limiting plates to press the counterweight blocks 9 and compact the counterweight blocks 9 during the assembly process. One side of the counterweight block 9 is provided with a slot, and the slot is compatible with the first threaded rod 3 to facilitate the insertion of the counterweight block 9 into the outer side of the first threaded rod 3 for assembly. The counterweight block 9 is located on the outer side of the first threaded rod 3.

[0021] Working principle: When the counterweight needs to be adjusted, first rotate the internal threaded tube 2 to adjust it downwards. After adjustment, install the counterweight block 9 on the outside of the first threaded rod 3. After installing an appropriate number of counterweight blocks 9, rotate the internal threaded tube 2 upwards to squeeze the counterweight block 9 and compact it into the counterweight chamber 8, thus completing the adjustment of the hand hammer counterweight. When the hand hammer head 4 is damaged, rotate the rotating plate 6 and the second threaded rod 5 upwards so that the second threaded rod 5 no longer limits the hand hammer head 4. Then pull the hand hammer head 4 out from the outside of the second threaded rod 5 to complete the disassembly of the hand hammer head 4. Then replace the hand hammer head 4.
