It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or modules that are not clearly listed or inherent to these processes, methods, products, or devices.

[0033] Reference Figure 1 A portable screwdriver of this embodiment includes a shell 1 and a cutter head assembly and a storage assembly installed on the shell 1.

[0034] Reference Figure 2 and Figure 3 The housing 1 is provided with a storage slot 3 on the other side of the cutter head assembly. The cutter head assembly includes a fixed cutter head 2 installed on one side of the housing 1 and a spare cutter head (not shown in the figure) stored in the storage slot 3. The fixed cutter head 2 is driven to rotate by the rotation of the motor so that the fixed cutter head 2 tightens or loosens the screw. The spare cutter head (not shown in the figure) needs to be stored in the storage slot 3 for use, which facilitates the storage of the spare cutter head and helps to improve the portability of the electric screwdriver.

[0035] Combination Figure 4 The housing 1 is provided with a fixing box 4 for fixing the spare cutter head in the storage slot 3. By storing the spare cutter head in the fixing box 4 and storing the fixing box 4 in the storage slot 3 of the housing 1, it is convenient to take the cutter head. By taking the fixing box 4 out of the storage slot 3, it is convenient to take the cutter head, which helps to improve the portability of the electric screwdriver.

[0036] In the implementation of the present application, the wall of the fixed box 4 is designed with a transparent plate, so that it is convenient to see the shape of the spare cutter head from the outside, which is helpful for selecting the spare cutter head. In addition, a partition 41 is fixed in the fixed box 4, wherein the four sides of the partition 41 are bonded to the wall of the fixed box 4. In addition, a plurality of positioning holes 42 for fixing the spare cutter head are provided on the partition 41, so as to facilitate the fixation of the spare cutter head and improve the stability of the spare cutter head. In the embodiment of the present application, the aperture of the positioning hole 42 is a hexagonal screw hole, and all the spare cutter heads and the fixed cutter head 2 connected to the housing 1 are hexagonal studs that are just snapped into the hexagonal screw holes.

[0037] Reference Figure 4 A slider 31 is integrally formed on the side wall of the housing 1 located at the storage groove 3, and a slide groove 43 for the slider 31 to slide through is opened on the outer wall of the fixed box 4, which facilitates the removal of the fixed box 4 from the storage box and improves the efficiency of storing the spare blade heads.

[0038] In addition, an anti-skid groove 431 is provided on the inner wall of the fixed box 4, and the design of the anti-skid groove 431 makes it easy to take the fixed box 4 out of the storage slot 3. At the same time, the bottom of the anti-skid groove 431 is provided with an anti-skid pattern 432, which further increases the friction force and facilitates the removal of the fixed box 4 from the storage slot 3. In addition, a rounded corner 433 is provided between the groove wall of the anti-skid groove 431 and the box wall of the fixed box 4 to reduce the probability of scratching fingers when taking out the fixed box 4.

[0039] Reference Figure 5 and Figure 6 The housing 1 is provided with a cover 5 in the opening direction of the fixed box 4, and the cover 5 is covered in the storage slot 3 so that the fixed box 4 is a closed space. Specifically, the cover 5 is parallel to the notch plane of the storage slot 3 to close the storage slot 3.

[0040] Reference Figure 6, the groove wall of the storage groove 3 includes a positioning portion 32, a limiting portion 33 and a clamping groove 34; wherein, the positioning portion 32 has two and is located on both sides of the limiting portion 33, and the clamping groove 34 is located on the opposite side of the limiting portion 33. Specifically, positioning strips 51 are integrally provided on both sides of the cover 5, and the positioning portions 32 on both sides are provided with positioning grooves 321 for the positioning strips 51 to slide through. The cover 5 is integrally provided with a limiting block 52 on one side of the limiting portion 33, and the limiting portion 33 is provided with a limiting groove 331 for passing and fixing the limiting block 52. In this embodiment, the cover 5 is passed through the clamping groove 34, and the positioning strips 51 on both sides of the cover 5 are passed through the positioning grooves 321 on the positioning portion 32 to achieve the positioning of the guide, and then the limiting block 52 on the cover 5 is passed through and fixed in the limiting groove 331, thereby realizing the cover 5 covering the storage groove 3, so that the spare blade head is stored in the fixed box 4. Moreover, in this example, a limiting card block can be provided on the limiting strip, and a card slot for the limiting card block to be engaged is provided in the limiting groove 331, thereby facilitating the unlocking of the limiting strip in the limiting block 52; in addition, anti-slip textures are also provided on the cover 5 to help slide the cover open.

[0041] Furthermore, the housing 1 is provided with a connection port 11 for charging the portable screwdriver on one side of the storage slot 3. In this embodiment, the connection port 11 is specifically a type-C interface, which not only facilitates the charging of the portable screwdriver, but also can adapt to more application environments. In addition, the housing 1 is provided with a clearance groove 12 on the side around the connection port 11 to reduce the risk of friction between the data cable and the outer edge of the housing 1.
