[0002] Pneumatic screwdriver bits, scientifically known as pneumatic screwdriver bits, are also called pneumatic screwdrivers because they use compressed air as power. Pneumatic screwdriver bits usually refer to screwdriver bits that are installed on electric drills or electric hammers to screw screws. Electric screwdriver bits are used to drive screwdrivers to tighten or loosen screws. They are small power tools. In order to facilitate the installation of bit heads, in actual application, pneumatic screwdriver bits are mostly installed on machines and equipment for use by setting connecting devices.

[0003] However, the connection device of the current electric drill bit needs to use different types of bits when tightening and loosening different types of screws. Traditional connection devices mostly use fastening screws to install and fix the bits. When different types of bits need to be used, they need to be disassembled and installed back and forth, which is cumbersome and inconvenient for quick replacement.

[0004] In order to solve the above problems, we propose a connecting device that is convenient for replacing the air screwdriver bit to solve the above problems. Utility Model Content

[0023] A groove 6 is provided on the back of the mounting tube 2, and the groove 6 is opened at the upper end of the mounting seat 1. A limit slot 7 is provided at the head end of the groove 6; a turntable 4 is rotatably installed in the middle of the inner side of the mounting seat 1, and a connecting rod 8 is movably installed in the middle of the upper end of the turntable 4. A limit block 9 is slidably installed on the periphery of the connecting rod 8, and the limit block 9 is adapted to the limit slot 7 and can be snapped.

[0024] Rotate the connecting rod 8 so that the connecting rod 8 can be moved into the groove 6, and then the limiting block 9 is engaged in the limiting groove 7 to limit and fix the connecting rod 8. At this time, the connecting rod 8 is located on the back of the pneumatic screwdriver head and is in a straight line with the pneumatic screwdriver head, so that it is convenient to rotate the connecting rod 8 to use the pneumatic screwdriver head.

[0025] Elastic components are provided on both sides of the bottom end of the limit block 9, and the limit block 9 is driven to move up and down by the elastic components; the elastic component includes a fixed sleeve 12, a movable rod 13 and a spring 14, the movable rod 13 is slidably installed in the middle of the inner side of the fixed sleeve 12, the bottom end of the spring 14 is fixedly installed at the inner bottom of the fixed sleeve 12, and the top of the spring 14 is connected to the bottom end of the movable rod 13; the fixed sleeve 12 is fixedly installed in the middle of the two ends of the connecting rod 8, and the top of the movable rod 13 is connected to the bottom end of the limit block 9.

[0026] When the limit block 9 slides on the surface of the connecting rod 8, the spring 14 will generate a pulling force. When the limit block 9 is connected to the limit slot 7, the limit block 9 is pulled by the spring 14 to prevent the limit block 9 from falling off and causing the connecting rod 8 to loosen.

[0027] A limiting block 11 is provided in the middle of the upper end of the limiting block 9 , and the limiting block 11 is slidably connected to the connecting rod 8 . Pulling the limiting block 11 can drive the limiting block 9 so that the limiting block 9 slides around the connecting rod 8 .

[0030] The working principle of the utility model is:

[0031] By arranging a plurality of mounting tubes 2 around the side ends of the mounting base 1, it is convenient for the user to install a plurality of types of air screwdriver bits. During use, the air screwdriver bits to be used are first installed and fixed around the mounting base 1 in sequence, and then wait for use.

[0032] During use, first, the rotary disk 4 is rotated to move the connecting rod 8 to the back of the air screwdriver head, and then the connecting rod 8 is rotated to allow the connecting rod 8 to fall into the groove 6;

[0033] At this time, by pulling the limit block 11, the limit card block 9 slides on the connecting rod 8. When the limit card block 9 slides toward the outer end of the connecting rod 8, the connecting rod 8 can be completely placed in the groove 6. Then, the pulling force on the limit card block 9 is released. Under the rebound of the spring 14, the limit card block 9 is driven to retract and slide, so that the limit card block 9 is inserted into the limit card slot 7 for clamping, thereby realizing the limit fixing of the connecting rod 8 and improving the stability of the air screwdriver head when it is used;

[0034] On the contrary, when the pneumatic screwdriver bit needs to be replaced, it is only necessary to pull the limit block 11 to make the limit block 9 fall off from the limit slot 7, and then the connecting rod 8 can be erected, so that it is convenient to rotate the turntable 4 to select a new pneumatic screwdriver bit for use.

[0035] The above structure makes it convenient for users to quickly replace the air screwdriver bit for use, thereby effectively improving work efficiency.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
