[0022] like Figures 1 to 3As shown, a multi-bit screwdriver of the utility model includes a handle and a bit 1. The bit 1 includes at least one model. Several bits 1 are connected to the handle through a rotating pair, so that the bit 1 rotates around the rotating pair to be folded or unfolded with the handle. Through the setting of the utility model, multiple bits 1 are set on a handle, which greatly reduces the overall weight. When in use, the bit 1 is rotated to be unfolded with the handle. When not in use, the bit 1 and the handle are folded to avoid the bit 1 piercing the fabric, which is more convenient to carry.

[0023] The handle of the utility model includes two rotating shafts 8, one rotating shaft 8 is used to rotate and connect the straight-shaped screwdriver bit 1, and the other rotating shaft 8 is used to rotate and connect the cross-shaped screwdriver bit 1. One side of the screwdriver bit 1 is bent to form a rotating hole, and the rotating shaft 8 is inserted into the rotating hole, so that the screwdriver bit 1 rotates around the rotating shaft 8. The handle also includes a side structure 4, which is arranged at both ends of the rotating shaft 8. A receiving cavity 7 is formed between the side structures 4, and the receiving cavity 7 is used to accommodate the screwdriver bit 1. A limiting member 6 is provided in the receiving cavity 7, and the distance between the limiting member 6 and the rotating shaft 8 is less than the length of the screwdriver bit 1. The limiting member 6 can be a fixed rod. When the screwdriver bit 1 rotates to the fixed rod, the screwdriver bit 1 enters the receiving cavity 7, and the fixed rod prevents the screwdriver bit 1 from rotating out of the receiving cavity 7.

[0024] The side structure 4 includes a fixed layer 2 and an anti-skid layer 3. The fixed layer 2 is used to fix the rotating shaft 8, and the anti-skid layer 3 is used to increase the friction force. The fixed layer 2 and the anti-skid layer 3 are overlapped. The anti-skid layer 3 is made of rubber material, and the surface of the anti-skid layer 3 is provided with a concave-convex texture, and the texture is used to increase the friction force. The end of the rotating shaft 8 is inserted into the through hole of the fixed layer 2, and the nut 5 is combined to fix the end on the fixed layer 2.

[0025] Several screwdriver bits 1 are arranged and distributed in order from small to large along the axial direction of the rotating shaft 8 according to the size of the model. A separator 9 is provided between adjacent screwdriver bits 1 / screwdriver bits 1 and the side structure 4. The separator 9 is used to separate the distance between adjacent screwdriver bits 1 / screwdriver bits 1 and the side structure 4. When adjacent screwdriver bits 1 are attached together, the friction between the screwdriver bits 1 will increase, and when one screwdriver bit 1 rotates, it will drive the other screwdriver bits 1 to rotate together, causing the screwdriver bits 1 to wear and other problems. The separator 9 reduces the contact area between the adjacent screwdriver bits 1 / screwdriver bits 1 and the side structure 4, thereby reducing the friction. The separator 9 is a gasket, and the gasket is provided with a through hole, and the rotating shaft 8 is inserted into the through hole, so that the gasket is set on the rotating shaft 8.

[0026] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
