[0027] Figure 2 This is a cross-sectional schematic diagram of an electric screwdriver adapter according to an embodiment of the present invention. Detailed Implementation

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0029] First, combine Figures 1-2The electric screwdriver adapter according to an embodiment of the present invention is used for the adaptation and installation of electric screwdrivers and has a wide range of applications.

[0030] like Figures 1-2 As shown, the electric screwdriver adapter of this utility model embodiment includes: adapter body 1, air tube 2 and conversion connector 3.

[0031] Specifically, such as Figures 1-2 As shown, in this embodiment, the top of the adapter body 1 is connected to the electric screwdriver. The electric screwdriver is inserted from the top of the adapter body 1 to the bottom of the adapter body 1, achieving a stable connection with the electric screwdriver through the adapter body 1. The bottom of the adapter body 1 is provided with an air source connector 5; one end of the air tube 2 is connected to the air source connector 5; the conversion connector 3 is fixed to the top of the adapter body 1, and the conversion connector 3 is connected to the other end of the air tube 2 and an external air source. Existing electric screwdriver adapters use a single air tube 2 directly connected to the air source at the air tube 2 connector. The air tube 2 is scattered and cannot be fixed. The bottom end of the adapter body 1 can rotate 360° during operation, which can easily interfere with or even damage the customer's product. By adding the conversion connector 3 fixed to the top of the adapter body 1, the air tube 2 is fixed, avoiding the air tube 2 being scattered and interfering. The rotation range of the bottom end of the adapter body 1 during operation is maintained within 15°, avoiding interference with the customer's product. The air source is connected through the air source connector 5, the air pipe 2 and the conversion connector 3. A negative pressure is generated in the adapter body 1 and transmitted to the surface of the screw head to form a suction force, thereby achieving the effect of non-magnetic screw picking.

[0032] Furthermore, such as Figures 1-2 As shown, in this embodiment, the adapter 3 has two interfaces that are interconnected and respectively connect to the other end of the air pipe 2 and an external air source.

[0033] Furthermore, such as Figures 1-2 As shown, in this embodiment, the adapter 3 is fixed to the top of the adapter body by screws 4, which is simple, reliable, and easy to assemble and disassemble.

[0034] Furthermore, such as Figures 1-2 As shown, in this embodiment, the air tube 2 is a silicone hose. The existing air tube 2 uses a PU air tube 2 for air supply. When the end at the bottom of the adapter body 1 is compressed, the air tube 2 will also bend, which will increase the bending force of the air tube 2 in addition to the spring pressure, making it easy for the pressure to exceed the limit. The bending force generated by the silicone hose is much smaller than that of the PU air tube 2, which can avoid the pressure exceeding the limit during operation.

[0035] Furthermore, such as Figures 1-2 As shown, in this embodiment, the length direction of the air tube 2 is parallel to that of the adapter body 1. At this time, the length of the air tube 2 is the shortest, which saves the material of the air tube 2 and reduces the cost.

[0036] Specifically, such as Figures 1-2 As shown, in this embodiment, the adapter body 1 includes: a cylindrical body 11, with a conversion connector 3 fixed to the top of the cylindrical body 11; a suction nozzle fixing end 12, which is installed at the bottom of the cylindrical body 11, and an air source connector 5 is provided on the side wall of the suction nozzle fixing end 12; a suction nozzle, which is installed at the bottom of the suction nozzle fixing end 12 and connected to the air source connector 5, with a partition plate inside the suction nozzle, which is integrally formed with the suction nozzle to ensure sealing, and the partition plate is positioned above the air source connector 5; and an electric screwdriver that passes through the cylindrical body 11 and the suction nozzle fixing end in sequence and extends into the suction nozzle. By placing the air source connector 5 at the lower part of the suction nozzle fixing end 12 and connecting it to the inner cavity of the suction nozzle, negative pressure is only generated in the inner cavity of the suction nozzle during operation and will not diffuse to other places, ensuring the airtightness of the inner cavity of the suction nozzle. There is a gap between the suction nozzle and the screwdriver bit to ensure air circulation, and the negative pressure inside the suction nozzle can be transmitted to the surface of the screw head being sucked up through the suction nozzle to form suction.

[0037] Furthermore, such as Figures 1-2 As shown, in this embodiment, a sealing ring is provided on the inner wall of the top of the cylinder 11. The sealing ring seals the electric screwdriver and the cylinder 11, further ensuring airtightness and improving the adsorption effect.

[0038] Furthermore, such as Figures 1-2 As shown, in this embodiment, the adapter body 1 further includes: an adjusting end 14, a buffer spring 15, and a stop nut 16; the inner wall of the cylinder 11 is provided with an internal thread, and the outer wall of the adjusting end 14 is provided with an external thread, and the cylinder 11 and the adjusting end 14 are threadedly connected; the suction nozzle fixing end 12 is slidably disposed at the bottom end of the adjusting end 14; the buffer spring 15 is disposed inside the cylinder 11, and the two ends of the buffer spring 15 abut against the cylinder 11 and the suction nozzle fixing end 12 respectively. Through the buffer spring 15, the suction nozzle fixing end 12 can move up and down, and the suction nozzle moves up and down accordingly, realizing soft contact between the suction nozzle and the screw, reducing product pressure loss; the stop nut 16 is screwed onto the adjusting end 14 and screwed into the mating position of the adjusting end 14 and the cylinder 11 to achieve locking and stopping.

[0039] Furthermore, such as Figures 1-2 As shown, in this embodiment, the adapter body 1 further includes a bearing, which is disposed between the adjusting end 14 and the suction nozzle fixing end 12. The bearing is a linear bearing, which can reduce the friction when the suction nozzle fixing end 12 slides up and down, and achieve smooth sliding.

[0040] Furthermore, such as Figures 1-2As shown, in this embodiment, the bottom end of the cylinder 11 is provided with a first step portion 111, and the top end of the adjusting end 14 is provided with a second step portion 141 that cooperates with the first step portion 111. Since the adjusting end 14 and the cylinder 11 are two separate components, simply relying on threaded tightening will result in a coaxiality deviation. Once misaligned, the suction nozzle at the bottom end of the adjusting end 14 will be crooked. For high-precision positioning tightening, the deviation is sufficient to cause tightening failure or even product scrap. The cooperation of the first step portion 111 and the second step portion 141 serves as a reference for installation and application, ensuring that the adjusting end 14 and the cylinder 11 are coaxial during adjustment, minimizing the risk of non-coaxiality.

[0041] Working principle: The adapter is assembled and installed on the electric screwdriver. It is connected to an external air source through the conversion connector 3. The air source creates a negative pressure cavity inside the suction nozzle. The adapter moves with the electric screwdriver to the designated screw picking position and moves vertically downward to pick up the screw. When picking up the screw, the suction nozzle contacts the screw and the buffer spring 15 avoids hard contact. It forms a suction force on the surface of the screw head to achieve non-magnetic picking up of the screw.

[0042] Above, refer to Figures 1-2 The electric screwdriver adapter according to an embodiment of the present invention is described. By adding a conversion connector and fixing the air tube, the air tube is effectively prevented from becoming tangled, the rotation range of the bottom end of the adapter is reduced, and interference and damage to the customer's product are avoided.
