[0029] In the embodiment, the sleeve plug-in section 31 of the connecting piece 3 is provided with a radial hole, which is sequentially provided with a ball 33 and a spring from outside to inside. The connecting hole of the nut sleeve 2 is provided with a positioning hole matched with the ball 33. This structure design makes the installation and disassembly process of the nut sleeve relatively simple, without the need for complex tools or operation steps. Users can easily connect and disassemble the nut sleeve with the connecting piece, improving work efficiency. Principle of power transmission: the power device 1 transmits power to the connecting section 32 of the connecting piece 3 through the output shaft 11. The rotation of the connecting section 32 drives the sleeve plug-in section 31 to rotate, thereby transmitting power to the nut sleeve 2. Connection method: the sleeve plug-in section 31 is inserted into the connecting hole of the nut sleeve 2. The spring pushes the ball into the positioning hole. When the nut sleeve rotates, the friction between the ball and the positioning hole makes the sleeve plug-in section and the nut sleeve relatively fixed, thereby realizing the transmission of power.

[0030] In the embodiment, as shown in Figure 2 the connecting piece is connected with the output shaft through a coupling. The connecting section 32 of the connecting piece 3 is connected with the output shaft 11 of the power device 1 through the coupling 4. The coupling 4 is internally formed with fixed holes matched with the connecting section 32 of the connecting piece 3 and the output shaft 11 of the power device 1. The outer wall of the coupling 4 is provided with a radial threaded hole. The jackscrew 41 is screwed into the threaded hole to abut against the corresponding connecting section 32 of the connecting piece 3 and the output shaft 11 of the power device 1. The fixed holes of the coupling 4 are matched with the connecting section 32 of the connecting piece 3 and the output shaft 11 of the power device 1, respectively. Through this close cooperation, the two can keep synchronous during rotation. When the output shaft 11 of the power device 1 rotates, the connecting section 32 of the connecting piece 3 also rotates. The jackscrew 41 screwed into the threaded hole plays a fastening role. By tightening the jackscrew 41, it can ensure that the connecting section 32 of the connecting piece 3 and the output shaft 11 of the power device 1 are tightly combined, preventing them from relatively displacing or loosening during operation. Accurate positioning: the coupling 4 can accurately position the output shaft of the power device 1 and the connecting section of the connecting piece 3, ensuring the accuracy of power transmission, which is crucial for some high-precision nut tightening operations. Stable connection: the jackscrew 41 makes the connection between the connecting section of the connecting piece 3 and the output shaft of the power device 1 more stable. Even under high load and high speed, it can ensure the reliability of the connection and prevent loosening or falling off. Easy to install and adjust: through the design of the threaded hole and the jackscrew, the installation and adjustment of the connecting piece 3 and the power device 1 are facilitated. During installation, the position of the jackscrew 41 can be adjusted according to actual needs to ensure the tightness of the connection.

[0031] In the embodiment, as shown in Figure 3As shown, the connecting piece is connected with the output shaft through a threaded connection, the connecting section 32 of the connecting piece 3 is formed with an internal thread, and the output shaft 11 of the power device 1 is formed with an external thread that is threadedly combined with the internal thread, and the connecting piece 3 is threadedly combined and fixed with the output shaft 11 of the power device 1. This threaded connection provides an efficient and stable connection scheme for power transmission of the nut tightening machine.

[0032] In the embodiment, the power device 1 is provided with a support 12, which provides support and stability for the power device. It can fix the power device at a specific position to ensure the stability during operation. Through the bolt hole and other structures on the support, the power device can be connected with other equipment or installation platform. At the same time, the design of the support can also disperse the weight of the power device, making it more stable during operation.

[0033] In the embodiment, the support 12 of the power device 1 is fixed on the bracket 5, which provides a stable support structure for the power device 1. The support 12 is fixed with the bracket 5 through bolts and other connecting pieces, ensuring that the power device will not shake or displace during operation. This is crucial for the normal operation of the equipment, especially in high-speed operation or under heavy vibration.

[0034] In the embodiment, the bracket 5 is fixed below the workbench 6, and the driving part 21 of the nut sleeve 2 is arranged upward.
