[0021] One or more embodiments of the present specification disclose a storage device for screw bits, comprising a pancake-shaped box body, wherein the box body comprises two parallel cover plates 1, and a connecting tube 4 is connected at the center of the two cover plates 1. A plurality of accommodating grooves 3 for accommodating screw bits are provided inside the box body, and the accommodating grooves 3 coincide with the radius of the cover plates 1. An opening for screw bits to enter and exit is provided at one end of the accommodating groove 3 facing the edge of the cover plate 1. An annular groove 8 is provided at the edges of the opposite surfaces of the two cover plates 1, and two slidingly connected arc plates 2 are provided in the annular groove 8. The arc plates 2 are semicircular structures, and one end of the two arc plates 2 is connected to an elastic sheet 5, and a notch is provided between the other ends of the two arc plates 2. The spacing between the notches is smaller than the outer diameter of the screw bit, and a pick 7 is fixed to the outer wall of the other end of the two arc plates 2.

[0022] like Figure 1-5The utensil 2 is a kind of box body of the present invention, and its outer cover is provided with an upper and lower rim, and the lower cover 1 is provided with the rim of the box body.

[0023] The operating principle of this storage device is that various types of screw bits are placed independently in the accommodating groove 3, and the two curved plates 2 form an annular plate that is approximately a complete circle. The curved plate 2 can rotate in the annular groove 8. When a screw bit needs to be taken out, the curved plate 2 is rotated by the paddle 7 so that the gap between the curved plates 2 is aligned with the opening of the accommodating groove 3 containing the required type of screw bit. Then the two paddles 7 are moved away from each other, so that the ends of the two curved plates 2 close to the gap are moved away from each other, thereby enlarging the gap. In this way, the screw bit in the accommodating groove 3 can leak out from the opening, and then leak out to the outside of the box body from the enlarged gap, thereby realizing the taking of the screw bit. After the screw bit is used, the gap is also enlarged by the paddle 7, and the screw bit is inserted into the accommodating groove 3 from the gap. The elastic piece at one end of the curved plate 2 keeps the gap at the other end of the curved plate 2 smaller than the outer diameter of the screw bit, so that the screw bit will not fall out of the gap during storage.

[0024] The bit storage device provided by the present invention aligns the notch with the receiving groove 3 by rotating the arc plate 2, and allows the bits to leak out by toggling the paddle 7, making it more convenient to take and place the required type of bits.

[0025] In some optional embodiments, the accommodating groove 3 includes two splints 14, and the two splints 14 are symmetrically arranged about the radius of the accommodating groove 3. The spacing between the two splints 14 is smaller than the outer diameter of the bit, and the end of the splint 14 close to the center of the cover plate 1 is hingedly connected to the cover plate 1, and an elastic piece three 16 is fixed on the back-to-opposite side of the end of the two splints 14 close to the edge of the cover plate 1. The end of the elastic piece three 16 is provided with a fixing block 15 fixed to the cover plate 1, and a shift rod 6 is fixed to the inner wall of the other end of the two curved plates 2. When the two curved plates 2 are rotated to the position where their notches are aligned with the opening of the accommodating groove 3, the two shift rods 6 are respectively pressed against the inner walls of the two splints 14.

[0026] The accommodating groove 3 includes two splints 14, which are symmetrical about the radius of the cover plate 1 on which they are located. The spacing between the splints 14 is smaller than the outer diameter of the screwdriver. One end of the splint 14 close to the center of the cover plate 1 is hingedly connected to the cover plate 1, and an elastic piece 3 16 is fixed to the opposite side of one end of the splint 14 close to the edge of the cover plate 1. The end of the elastic piece 3 16 is fixed with a fixing block 15, and the fixing block 15 is fixedly arranged on the cover plate 1. The elastic piece 3 16 makes the spacing between the two splints 14 remain smaller than the outer diameter of the screwdriver. A lever 6 is fixed to the inner wall of the other end of the two curved plates 2. When the two curved plates 2 are rotated to the position where the notch is aligned with the opening of the accommodating groove 3, the two levers 6 move between the two splints 14, and the two levers 6 respectively abut on the inner walls of the two splints 14. When the screwdriver is stored, it is clamped by the two splints 14, which can reduce the shaking of the screwdriver. The user rotates the curved plate 2 by the paddle 7. When the notch is When the notch of the curved plate 2 is aligned with the opening of the accommodating groove 3, the two levers 6 are located between the clamping plates 14, and the rotation of the curved plate 2 is resisted, which can assist workers to quickly identify whether the notch of the curved plate 2 is aligned with the opening of the accommodating groove 3.

[0027] In some optional embodiments, an extension plate 17 extending outward is fixed to one end of the two clamping plates 14 near the edge of the cover plate 1. When the two arc-shaped plates 2 are rotated to a position where their notches are aligned with the openings of the accommodating grooves 3, the two levers 6 are respectively supported on the inner walls of the two extension plates 17.

[0028] The two extension plates 17 are approximately in an eight-shape, and the lever 6 is supported on the inner wall of the extension plate 17. When the levers 6 are away from each other for a certain distance, the extension plates 17 are stretched open, and then the clamping plates 14 are stretched open, so that the screw bits can leak out. The lever 6 is supported on the inner wall of the extension plate 17. It is only necessary to separate the lever 6 for a short distance so that the clamping plates 14 no longer clamp the screw bits, which facilitates the leakage of the screw bits and the lever 6 will not interfere with the leakage of the screw bits.

[0029] In some optional embodiments, the connecting tube 4 is a hollow structure, and an annular magnet 10 is embedded in the inner wall of the connecting tube 4. The outer wall of the connecting tube 4 is provided with a plurality of through holes 9 corresponding one to one with the accommodating grooves 3. An elastic piece 2 12 is passed through the through hole 9, and one end of the elastic piece 2 12 is fixedly connected to the outer wall of the magnet 10, and the other end of the elastic piece 2 12 extends between the two clamping plates 14 of the accommodating groove 3, and the other end of the elastic piece 2 12 is fixed with a support plate 13.

[0030] The second elastic piece 12 and the support plate 13 are both made of metal material that is attracted by the magnet 10. The magnet 10 makes the support plate 13 magnetic, and the support plate 13 transfers the magnetism to the screwdriver bit, thereby magnetizing the screwdriver bit.

[0031] In some optional embodiments, a protrusion 11 is fixed to the inner wall of one end of the two clamping plates 14 close to the edge of the cover plate 1 .

[0032] In order to prevent the bit from being separated from the support plate 13 and unable to be magnetized well during storage, a protrusion 11 is provided on the inner wall of one end of the splint 14. The bit is placed between the two splints 14 and falls on the support plate 13. The elastic piece 2 12 is compressed due to gravity. Then the two paddles 7 are released and the two splints 14 are closed under the action of the elastic piece 3 16. The support plate 13 is held against one end of the bit and the protrusion 11 is located at the other end of the bit. The two limit the bit so that the bit is held against the support plate 13 and keeps in contact with the support plate 13, thereby magnetizing the bit.

[0033] In some optional embodiments, the two paddles 7 are symmetrical semi-conical in shape.

[0034] The position for installing the bit at the front end of the hand drill is approximately in the shape of a cone. When installing the bit, the two picks 7 are attached to the front end of the hand drill, and the semi-conical shape is attached to the front end of the hand drill. The front end of the hand drill opens the picks 7, and the bit automatically falls into the position for installing the bit of the hand drill, making the bit installation procedure very simple.
