[0033] The first round head portion 410 and the second round head portion 510 are both exposed outside the wheel shell 100, which is convenient for grasping on the one hand, and can clamp the wheel shell 100 and the cover 200 on the other hand, so that the wheel shell 100 and the cover 200 are restricted between the first round head portion 410 and the second round head portion 510; the first rotating portion 420 and the second rotating portion 520 are convenient for the rotation of the wheel shell 100 and the cover 200; the square tenon 540 is embedded in the square tenon groove 440 to prevent the first central axis 400 and the second central axis 500 from rotating relative to each other; the cross-section of the first square column 430 and the cross-section of the second square column 530 are congruent, which is convenient for the insertion of the ratchet 300; the ratchet 300 is inserted into the first square column 430 and the second square column 530 based on the square through hole 310, which can prevent the ratchet 300 from rotating relative to the first central axis 400 and the second central axis 500, thereby ensuring that the ratchet 300 is controlled by the first central axis 400 and the second central axis 500.

[0034] In some specific embodiments, the edges of the first round portion 410 and the second round portion 510 are rounded to form smooth arc surfaces that do not hurt the hands.

[0035] In some specific embodiments, see Figure 3 、 5 and 6, the first central axis 400 is recessed from the first round head 410 toward the first square column 430 to form a first polygonal hole 450, and the second central axis 500 is recessed from the second round head 510 toward the second square column 530 to form a second polygonal hole 550. The existence of the first polygonal hole 450 and the second polygonal hole 550, on the one hand, is convenient for grasping, and on the other hand, can be used to match the screwdriver bits (screwdriver bits) to form a screwdriver tool for use. Specifically, insert a suitable screwdriver bit, such as a flathead, cross, Pozidriv, star, plum blossom, or hexagonal screwdriver bit into the first polygonal hole 450 or the second polygonal hole 550; then, hold the wheel housing 100 and align the screwdriver bit with the screw, rotate the wheel housing 100 with appropriate force, and then use the one-way rotation function of the decompression ratchet screwdriver to continuously tighten or loosen the screw, which is conducive to improving work efficiency.

[0036] Furthermore, the interior of the first polygonal hole 450 and the interior of the second polygonal hole 550 are magnetized to form a magnetic layer, which has weak magnetism and can absorb the screwdriver bit, making it easier to install and use the screwdriver bit.

[0037] In some specific embodiments, an annular cavity is formed inside the ratchet 300, and the annular cavity surrounds the square through hole 310, which can make the sound produced by the continuous collision between the pawl 600 and the ratchet 300 clearer and louder, and better relieve psychological pressure.

[0038] In some specific embodiments, the number of the shifting blocks 110 is 6, 8, or 10, making it easier to move the keys. Specifically, the edges of each of the shifting blocks 110 are rounded, making the touch more comfortable and aesthetically pleasing to the fingertips.

[0039] In some specific embodiments, see Figure 1 and Figure 4The inner circumference of the wheel housing 100 is provided with a plurality of pawl mounting grooves 130, and the plurality of pawls 600 are movably embedded in the plurality of pawl mounting grooves 130. A spring 610 is disposed in each pawl mounting groove 130, and each spring 610 abuts against the bottom surface of the corresponding pawl 600. Under the action of the spring 610, the pawl 600 and the ratchet 300 engage. The pawl 600 is movably embedded in the pawl mounting groove 130, and is blocked by the ratchet 300 to prevent it from falling. At the same time, the pawl 600 is elastically engaged with the ratchet 300 based on the spring 610, facilitating unidirectional rotation of the wheel housing 100 relative to the ratchet 300.

[0040] In some specific embodiments, the ratchet wheel 300 has a number of teeth ranging from 30 to 34, a tooth tip diameter ranging from 4 to 6 mm, and a module ranging from 0.117 to 0.200. This makes the sound produced by the collision between the ratchet wheel 300 and the pawl 600 clearer, louder, and more rhythmic, which is more conducive to relieving people's psychological stress. Moreover, such a ratchet wheel 300 is strong and durable, with a long service life. Specifically, the ratchet wheel 300 has 32 teeth, a tooth tip diameter of 4 mm, and a module ranging from 0.125, which makes it easy to accurately match with the pawl 600, so that the ratchet wheel 300 rotates in a coordinated manner.

[0041] In some specific embodiments, there are two pawls 600. The two pawls 600 are arranged opposite each other, which can also make the sound produced by the collision between the ratchet wheel 300 and the pawl 600 clearer, louder, and more rhythmic, which is more conducive to relieving people's psychological stress. Specifically, each pawl 600 has two claws, which accurately cooperate with the ratchet wheel 300 to ensure coordinated rotation of the ratchet wheel 300.

[0042] In some specific embodiments, the decompression ratchet screwdriver is a metal ratchet screwdriver, which is durable, feels good, and is easy to play.

[0043] The decompression ratchet screwdriver of the present invention can be played with at any time. By pinching the ends of the first central axis 400 and the second central axis 500 and unidirectionally shifting or rolling the wheel housing 100, the pawl 600 and the ratchet 300 continuously collide, thereby emitting a rhythmic and crisp sound, which can effectively relieve psychological stress, reduce peak anxiety, and allow people to relax immediately and quickly adjust their mental state. Moreover, decompression ratchet screwdrivers are relatively rare on the market, giving people a strong sense of novelty and good fun. In addition, the decompression ratchet screwdriver of the present invention can also be used as an everyday tool, used to continuously tighten or loosen screws in conjunction with a screwdriver bit, which is conducive to improving work efficiency.
