[0028] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] Example 1

[0030] Please refer to Figure 1 As shown, this embodiment provides a bit storage device, which includes: a shell 100 with an opening and a lifting assembly 200, the lifting assembly 200 is movably arranged inside the shell 100, the lifting assembly 200 is used to place the bit 300, the lifting assembly 200 is driven to move relative to the shell 100, and drives the bit 300 to extend or retract through the opening of the shell 100.

[0031] Please refer to Figure 1 As shown, in the present embodiment, the shell 100 is configured as a hollow columnar structure, one end of the shell 100 is closed, and the other end is open for easy removal of the bit 300 from the opening. The lifting assembly 200 is movably disposed inside the shell 100, and the lifting assembly 200 can place and fix multiple bits 300 in order. The lifting assembly 200 is driven to move relative to the shell 100, thereby driving the bit 300 placed on the lifting assembly 200 to move, so that the bit 300 is exposed from the opening of the shell 100 or retracted into the shell 100. In the present embodiment, the depth of the storage space in the shell 100 is greater than the length of the bit 300, so that the bit 300 can be completely retracted into the shell 100, so as to better store and protect the bit 300 and prevent the bit 300 from falling and being lost. Please refer to Figure 4 As shown, Figure 4 This is one of the use state diagrams of a screwdriver bit storage device provided in this embodiment. At this time, the screwdriver bits 300 are completely retracted into the housing 100, and the screwdriver bits 300 are stored in order. Figure 5 As shown, Figure 5 This is a second usage diagram of a bit storage device provided in this embodiment. At this time, the lifting assembly 200 is driven to drive the bit 300 to rise, so that the bit 300 is exposed from the opening of the shell 100, which is convenient for the operator to select and take the bit 300 to be used.

[0032] Optionally, in some implementations of the present embodiment, the lifting assembly 200 includes a rotating seat 201 and a lifting sleeve 202. The rotating seat 201 is rotatably connected to the shell 100, and the lifting sleeve 202 is sleeved on the rotating seat 201. A spiral lifting groove 2021 is provided on the lifting sleeve 202. A lifting protrusion 2011 is correspondingly provided on the rotating seat 201. The lifting protrusion 2011 is slidably clamped in the lifting groove 2021. The rotating seat 201 is driven to rotate and drives the lifting sleeve 202 to extend or retract through the opening of the shell 100, and the screwdriver bit 300 is placed on the lifting sleeve 202.

[0033] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the rotating seat 201 is rotatably arranged on the housing 100, and the lifting sleeve 202 is sleeved on the rotating seat 201. The lifting sleeve 202 is provided with spiral lifting grooves 2021 at intervals, and the rotating seat 201 is correspondingly provided with lifting protrusions 2011, and the lifting protrusions 2011 are slidably clamped in the lifting grooves 2021. The rotating seat 201 is rotatably connected to the housing 100, and only rotates around the rotating axis. The lifting sleeve 202 is lifted and moved along the length direction of the housing 100 under the action of the lifting protrusions 2011 and the lifting grooves 2021, thereby driving the screwdriver bit 300 placed on the lifting sleeve 202 to be lifted and lowered, so that the screwdriver bit 300 is exposed from the opening of the housing 100 or recovered into the housing 100. The screwdriver bit storage device provided in this embodiment adopts a rotating method to lift the screwdriver bit 300, which is convenient for the operator to operate quickly. The lifting protrusion 2011 and the spiral lifting groove 2021 have a certain self-locking effect. When the rotating seat 201 is rotated to lift the lifting sleeve 202, the lifting sleeve 202 remains stable and will not retract into the housing 100 due to self-generated gravity. On the contrary, after the lifting sleeve 202 is retracted into the housing 100, the lifting sleeve 202 will not be exposed from the housing 100 due to external shaking or inversion, thereby ensuring the stability of the screwdriver bit 300 when stored.

[0034] Optionally, in some implementations of the present embodiment, a placement rack 400 is disposed on the lifting sleeve 202 , and a fixing component 401 is disposed on the placement rack 400 . The fixing component 401 is used to fix the bit 300 placed on the placement rack 400 .

[0035] Please refer to Figure 1As shown, in this embodiment, the placement rack 400 is connected to the lifting sleeve 202, and a storage space is formed between the placement rack 400 and the housing 100 for placing the screwdriver bits 300 to be stored. A fixing assembly 401 is provided on the placement rack 400. Optionally, the fixing assembly 401 can be a plurality of placement slots or fixing buckles arranged evenly spaced in the circumferential direction, and the screwdriver bits 300 to be stored are placed in the placement slots or fixing buckles one by one. At present, the screwdriver bits 300 on the market are usually provided with a hexagonal connection portion 2014 for connecting an electric screwdriver. Therefore, the placement slot or fixing buckle can be set to a hexagonal structure, so as to firmly place the screwdriver bits 300 and prevent the screwdriver bits 300 from shaking and falling. Under the action of the fixing assembly 401, each placed screwdriver bit 300 is fixed, maintained in an orderly arrangement, and will not be confused due to external shaking, so as to facilitate the quick selection of the screwdriver bit 300 of the corresponding model during subsequent use.

[0036] Optionally, in some other embodiments, the fixing component 401 may be configured as a structure adapted to the bit 300 according to the shape of the bit 300 to be placed.

[0037] Optionally, in some implementations of this embodiment, a connecting buckle 2022 is provided on the lifting sleeve 202 , a slot 402 is provided on the placement rack 400 , and the placement rack 400 is detachably connected via the connecting buckle 2022 and the slot 402 .

[0038] Please refer to Figure 1 and Figure 2As shown, in this embodiment, the sleeve and the placement rack 400 are detachably connected, and the placement rack 400 can be replaced according to the needs of use. It can be understood that the screwdriver bits 300 commonly used in the market currently have different shapes, such as the common straight shape, cross shape, five-pointed star shape, regular hexagon shape, etc., and each shape of the screwdriver bits 300 has different sizes, resulting in a large number of screwdriver bits 300 models. The storage space in the housing 100 is limited. If all types of screwdriver bits 300 are stored, the volume and weight of the housing 100 will be large, which is inconvenient to carry. And when using, according to the use scenario, several fixed models of screwdriver bits 300 are often used, so it is sufficient to carry the corresponding number of screwdriver bits 300. Before production, assembly or use, the use scenario can be preset, and the screwdriver bits 300 that may be used in the scenario can be grouped into a group and fixed on a placement rack 400. For example, if the preset screwdriver usage scenario is small appliance repair, the screwdriver bit 300 that may be used in this scenario is a cross-shaped or straight-shaped screwdriver bit 300. Several cross-shaped or straight-shaped screwdriver bits 300 of different sizes are grouped together and placed on a placement rack 400. When small appliance repair is required, the original placement rack 400 only needs to be removed from the lifting sleeve 202, and then the placement rack 400 with the group of screwdriver bits 300 is connected to the lifting sleeve 202. When using multiple scenarios, different screwdriver bits 300 can be matched according to the usage requirements of different scenarios and fixed on the placement rack 400. When different types of screwdriver bits 300 need to be carried and used, the entire group of screwdriver bits 300 can be quickly replaced by simply replacing the placement rack 400, which is fast and convenient to operate. And when there are a large number of screwdriver bits 300, it is only necessary to configure multiple placement racks 400, without configuring multiple screwdriver bit storage devices, thereby achieving the purpose of cost saving. In this embodiment, the connection buckle 2022 on the lifting sleeve 202 has a certain elasticity. On the one hand, it can ensure the stability of the connection buckle 2022 when it is connected with the card slot 402. On the other hand, the connection buckle 2022 can be pressed to deform the connection buckle 2022, so that it can be easily separated from the card slot 402, and the placement rack 400 can be conveniently disassembled. When the placement rack 400 needs to be replaced, the rotating seat 201 is rotated to lift the lifting sleeve 202 to the maximum position, and then the lifting sleeve 202 and the placement rack 400 are taken out of the shell 100 together, and then the connection buckle 2022 is pressed to disassemble the placement rack 400, and finally another placement rack 400 is connected to the lifting sleeve 202, and the lifting sleeve 202 is installed back into the shell 100, which is convenient and quick to operate.

[0039] Optionally, in some other embodiments, the lifting sleeve 202 and the placement rack 400 may also be detachably connected by bolts, bonding or other methods.

[0040] Optionally, in some implementations of this embodiment, a guide groove 403 is provided on the placement rack 400 , and a guide bar 101 is provided on the inner side wall of the shell 100 , and the guide bar 101 is clamped in the guide groove 403 .

[0041] Please refer to Figure 3 As shown, in this embodiment, the inner side wall of the shell 100 is provided with one or more guide bars 101 along the extension direction of the opening, and the lifting and lowering movement direction of the lifting sleeve 202 is consistent with the length direction of the guide bar 101. A guide groove 403 is provided on the placement rack 400, and the guide groove 403 is slidably matched with the guide bar 101. When the lifting sleeve 202 is lifted and lowered, under the limiting and guiding action of the guide bar 101 and the guide groove 403, the lifting sleeve 202 and the placement rack 400 only move in a straight line direction in the shell 100, so as to prevent the lifting sleeve 202 and the placement rack 400 from rotating due to the rotation of the rotating seat 201, which affects the normal lifting and lowering of the lifting sleeve 202, and ensure the stability of the lifting sleeve 202 and the placement rack 400 when they are lifted and lowered.

[0042] Optionally, in some implementations of this embodiment, a limiting protrusion 1011 is provided on the guide bar 101, and an elastic buckle 404 is correspondingly provided on the placement rack 400. The elastic buckle 404 can abut against the limiting protrusion 1011, and the elastic buckle 404 will be detached from the limiting protrusion 1011 after the force applied to it exceeds a threshold.

[0043] Please refer to Figure 3 As shown, in this embodiment, a plurality of limiting protrusions 1011 are provided on the guide bar 101, and the limiting protrusions 1011 can be provided at both ends of the guide bar 101, so as to limit the maximum lifting height and the maximum retracting depth of the lifting sleeve 202. When the lifting sleeve 202 rises to the maximum height, the elastic buckle 404 on the placement rack 400 abuts against the limiting protrusion 1011, so as to prevent the lifting sleeve 202 from falling off from the housing 100 after continuing to rise, and other accidents. On the contrary, when the lifting sleeve 202 retracts, the limiting protrusion 1011 at the lower end plays a limiting role, so as to prevent the lifting sleeve 202 from colliding with other components and being damaged. The elastic buckle 404 on the placement rack 400 can be deformed, and when the force exceeds the threshold value, the elastic buckle 404 is deformed, and at this time the placement rack 400 can be free from the restriction of the limiting protrusion 1011. When it is necessary to remove the lifting sleeve 202 and replace the placement rack 400, the operator rotates the rotating seat 201 to lift the lifting sleeve 202. After the elastic buckle 404 is engaged with the limiting protrusion 1011, a certain rotational force is continued to be applied. At this time, the elastic buckle 404 is deformed when the force exceeds the threshold, and the placement rack 400 is separated from the limiting protrusion 1011 and continues to rise, and then the lifting sleeve 202 can be taken out. The limiting protrusion 1011 is set on the guide bar 101 to limit the moving range of the lifting sleeve 202, thereby protecting the lifting sleeve 202, preventing the lifting sleeve 202 from falling or being damaged, and improving the service life of the device.

[0044] Optionally, in some embodiments of the present embodiment, the rotating base 201 includes a supporting base 2012 and a lifting knob 2013, the supporting base 2012 is arranged inside the shell 100, a through hole is opened on the shell 100, the lifting knob 2013 is rotatably arranged outside the shell 100, and the lifting knob 2013 has a connecting portion 2014, the connecting portion 2014 extends through the through hole to the interior of the shell 100 and is detachably connected to the supporting base 2012.

[0045] Please refer to Figure 1 As shown, in this embodiment, a through hole is provided at the bottom of the housing 100, and a lifting knob 2013 is arranged at the bottom of the housing 100, and a connecting portion 2014 of the lifting knob 2013 extends through the through hole to the inside of the housing 100, thereby connecting to a support seat 2012 inside the housing 100. The lifting knob 2013 is exposed to the outside of the housing 100, so that an operator can drive the lifting knob 2013 to rotate. The lifting sleeve 202 is sleeved on the outside of the support seat 2012, and the lifting protrusion 2011 is arranged on the supporting peripheral wall, and cooperates with the lifting groove 2021 of the lifting sleeve 202. When the operator rotates the lifting knob 2013, the lifting knob 2013 drives the support seat 2012 to rotate, and then the lifting protrusion 2011 on the support seat 2012 is lifted or retracted to adjust the lifting, thereby realizing the function of lifting and lowering the screwdriver 300 placed on the lifting sleeve 202.

[0046] Optionally, in some implementations of this embodiment, the connecting portion 2014 is provided with a connecting spline 2015, and a keyway is correspondingly provided on the support seat 2012, and the spline is inserted into the keyway, so that the lifting knob 2013 and the support seat 2012 rotate synchronously.

[0047] Please refer to Figure 1 As shown, in this embodiment, the lifting knob 2013 and the support seat 2012 can be manufactured separately and then assembled. During installation, the lifting knob 2013 and the support seat 2012 are respectively assembled with the outside and the inside of the housing 100, and then can be connected by screws. Optionally, the connecting portion 2014 of the lifting knob 2013 can be set as a polygonal structure, or a spline is set on the peripheral wall of the connecting portion 2014, and a polygonal mounting hole or keyway is correspondingly opened on the support seat 2012.
