[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In this embodiment:

[0026] A pneumatic blower with exhaust function, such as Figures 1-4 As shown, the device includes an electric screwdriver body 1 and a storage compartment 5. The storage compartment 5 is fixed to the top of the electric screwdriver body 1, and the outer side of the storage compartment 5 is provided with several sets of groove-shaped structures arranged in a circular array for engaging with a rotating plate 12. It is rotatably connected to the rotating plate 12 via a rotating shaft. A storage box 13 is fixed to the inner side of the rotating plate 12, and a second connecting block 15 is fixed to the side of the storage box 13 away from the rotating plate 12. A connecting rod 11 is rotatably connected inside the second connecting block 15. A limit rod 6 is fixed to the middle of the inner side of the storage compartment 5, and a sliding seat 7 is slidably provided on the outer side of the limit rod 6.

[0027] The storage compartment 5 is directly fixed to the top of the electric screwdriver body 1, which effectively saves space and makes the electric screwdriver more portable. The circumferential array groove structure on the outside of the storage compartment 5 and the locking design of the rotating plate 12, together with the rotating shaft, realize the rotational connection, so that the storage box 13 can rotate smoothly to the outside of the storage compartment 5, which is convenient for the removal and placement of the blade. When it is necessary to open the storage box 13, simply drive the sliding seat 7 to slide on the limiting rod 6, and then let the first connecting block 10 push the second connecting block 15 through the connecting rod 11, so that the storage box 13 rotates to the outside along with the rotating plate 12, realizing the quick replacement or storage of the blade.

[0028] See Figure 1 , Figure 2 , Figure 3 and Figure 4 A pull rod 8 is fixed to the top of the sliding seat 7 and is sleeved with the limiting rod 6. A pull tab 9 is fixed to the top of the pull rod 8.

[0029] The pull rod 8 fixed at the top of the sliding seat 7 is sleeved with the limit rod 6, which ensures the stability and smoothness of the pull rod 8 during the sliding process. The pull plate 9 fixed at the top of the pull rod 8 provides the operator with a component that is easy to hold and operate, making it easier and less strenuous to pull the pull rod 8 to drive the sliding seat 7 to rise or fall.

[0030] See Figure 1 The outer surface of the electric screwdriver body 1 is provided with an electric screwdriver charging port 2, and the bottom of the electric screwdriver body 1 is provided with an electric screwdriver grip 3, and the electric screwdriver blade 4 is magnetically attached inside the electric screwdriver grip 3.

[0031] The electric screwdriver body 1 has a charging port 2 on its outer surface, which allows the electric screwdriver to be charged quickly and easily when the power is depleted, improving the efficiency and convenience of the electric screwdriver. The operator can quickly replace the old electric screwdriver bit 4 by simply pulling it off and aligning the new electric screwdriver bit 4 with the magnetic position of the grip part 3.

[0032] See Figure 1 The top of the electric screwdriver head 4 has a cross-shaped groove structure;

[0033] The "+" shaped groove design facilitates quick replacement of the cutting head. Because the structure has a clear positioning and guiding function, the operator can quickly and accurately align the new cutting head and insert it into the electric screwdriver body 1 when changing the cutting head, without the need for complicated adjustments or calibrations, which greatly improves work efficiency.

[0034] See Figure 2 , Figure 3 and Figure 4 The storage box 13 has a groove-shaped structure inside, and a locking block 14 is fixed inside the groove-shaped structure, which is compatible with and engages with the "+" shaped groove-shaped structure on the top of the electric screwdriver head 4.

[0035] The slotted structure inside the storage box 13 and the fixed locking block 14 are adapted to and locked into the cross-shaped slotted structure on the top of the electric screwdriver head 4. This design ensures that the head will not shake or fall off when stored, thereby avoiding the risk of damage to the head due to collision during carrying or storage.

[0036] See Figure 2 , Figure 3 and Figure 4The outer side of the sliding seat 7 has several sets of first connecting blocks 10 arranged in a circular array, and is rotatably connected to the bottom of the connecting rod 11.

[0037] Among them, several sets of first connecting blocks 10 arranged in a circular array on the outer side of the sliding seat 7 are rotatably connected to the bottom of the connecting rod 11. This design allows the connecting rod 11 to move synchronously through the first connecting blocks 10 when the sliding seat 7 slides on the limiting rod 6.

[0038] The implementation principle of this embodiment is as follows: First, the electric screwdriver body 1 is opened, causing the electric screwdriver head 4 at the bottom to rotate for operation. When the operation is finished or the electric screwdriver head 4 needs to be replaced, the pull tab 9 at the top of the pull rod 8 can be pulled, causing the pull tab 9 to drive the pull rod 8 to rise. This causes the pull rod 8 to drive the sliding seat 7 at the bottom and several sets of first connecting blocks 10 fixed on the outside of the sliding seat 7 to rise synchronously. The rise is limited by the limit rod 6. Then, the first connecting block 10 drives one end of the connecting rod 11 rotatably connected to it to rise. The lever 11 is raised, which pushes the second connecting block 15, which is rotatably connected to the other end. The second connecting block 15 then pushes the rotating plate 12 through the storage box 13, causing the rotating plate 12 to rotate through the rotating shaft rotatably connected to the storage compartment 5. This allows the storage box 13 to rotate to the outside of the storage compartment 5. Then, the blades inside the storage box 13 can be selected and replaced with the electric screwdriver blade 4 or stored. Finally, the storage box 13 is retracted into the storage compartment 5 by pressing down the pull tab 9.
