Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] A hammer for quality supervision and testing in construction projects, referring to Figure 1-5 ,include:

[0028] Hammer head 1 is the main working part of the hammer, used to directly strike building components;

[0029] The placement groove 6, which is opened on one side of the hammer head 1, provides installation space for the counterweight block 4 and the positioning block 3 described below;

[0030] Hammer handle 2 is detachably connected to hammer head 1, which facilitates the replacement and maintenance of hammer handle 2, and is also easy to carry and store.

[0031] The positioning block 3 is inserted into the placement slot 6. The two sides of the positioning block 3 near the striking part of the hammer head 1 are inclined and parallel to each other. This inclined setting cooperates with the inclined opening 5 on the counterweight block 4. When adjusting the position of the counterweight block 4, the counterweight block 4 can be more stably fixed on the positioning block 3 and is not easy to shake.

[0032] Multiple counterweights 4 of equal thickness are provided and are fitted onto the positioning block 3. The cross-section of the counterweight 4 is the same as the cross-section of the placement groove 6, and the side of the counterweight 4 abuts against the side of the placement groove 6.

[0033] The bevel 5 is opened on the counterweight 4. The positioning block 3 passes through multiple bevels 5, and the bevels 5 correspond to the side of the positioning block 3. The design of the bevel 5 and the inclined side of the positioning block 3 cooperate with each other, so that the counterweight 4 can be stably fixed on the positioning block 3, preventing the counterweight 4 from shifting during the hammering process.

[0034] The oblique openings 5 ​​on the counterweight blocks 4 located on the positioning block 3, which are close to the hammer handle 2 and far from the hammer handle 2, are in the same position. By sliding different numbers of counterweight blocks 4 along the positioning block 3 to the appropriate position, the weight of the hammer head 1 can be adjusted. The counterweight blocks 4 at the corresponding positions are interchangeable, so that no special correspondence is required when adjusting the counterweight, which provides convenience for adjusting the counterweight.

[0035] For example, a lighter hammer is used for detailed inspection of welds on thinner steel plates, while a heavier hammer may be needed for welds on thicker steel plates or large steel structure joints to ensure that any internal defects can be detected. The weight can be added or removed as needed. This method also applies to the inspection of other related masonry structures, concrete structures, timber structures, and interior decoration structures; further examples are not provided here.

[0036] The counterweight 4 can be set in an even number, preferably four. The two counterweights 4 located at the edge can be interchangeable, and the two counterweights 4 located in the middle can be interchangeable. The total thickness of the multiple counterweights 4, the thickness of the positioning block 3, and the depth of the placement groove 6 are equal. This setting can ensure that the counterweights 4, positioning blocks 3 and placement groove 6 fit tightly inside the hammer head 1, avoiding gaps and ensuring the stability and reliability of the overall structure of the hammer.

[0037] The hammer handle 2 is T-shaped, and two positioning pins 7 are fixedly installed on the side of the hammer handle 2 near the hammer head 1. The positioning pins 7 are inserted into the hammer head 1. The T-shaped design of the hammer handle 2 makes it easy for the user to hold, providing a better grip and operational stability. The positioning pins 7 can accurately position and connect the hammer handle 2 and the hammer head 1, enhancing the strength of the connection.

[0038] A bolt is inserted into the side of the hammer head 1 away from the hammer handle 2, and the bolt is connected to the positioning block 3 by threads. By connecting the positioning block 3 with bolts, the positioning block 3 can be firmly fixed in the placement groove 6 of the hammer head 1, preventing the positioning block 3 from loosening or falling off during use.

[0039] The counterweight 4 is designed in the shape of a strip, and both the edge of the counterweight 4 facing the hammer handle 2 and the opposite edge are chamfered. The strip-shaped design of the counterweight 4 allows for better arrangement within the placement slot 6, improving space utilization. The chamfering prevents the edges of the counterweight 4 from scratching the user and also facilitates the sliding and installation of the counterweight 4 within the placement slot 6.

[0040] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
