[0002] In modern industrial automation, instrumentation, and the Internet of Things (IoT), the CAN bus, as a highly efficient serial communication network, is widely used for data transmission between devices. However, CAN bus devices typically require wired connections for communication, which presents limitations in some application scenarios. For example, in equipment debugging, remote monitoring, and situations requiring frequent mobile device movement, wired connections may be constrained by cabling limitations, increasing the complexity of installation and maintenance.
[0003] Bluetooth technology, as a wireless communication technology, boasts advantages such as low power consumption, low cost, and ease of implementation, and has been widely used in the field of wireless communication. Therefore, there is a need to design a bus device that combines Bluetooth technology with the CAN bus to achieve data conversion between Bluetooth and CAN buses. Furthermore, current bus devices are typically secured with screws, requiring tools for disassembly and maintenance, leading to inconvenience. Utility Model Content

The circuit board and the power module are installed in the inner compartment of the housing. The power module is electrically connected to the circuit board, and a communication unit is provided on the circuit board.
[0007] The connecting assembly consists of a handle, a movable plate, a limiting block, and a compression spring. The movable plate is located inside the housing. Limiting blocks are fixedly installed at both ends of the front side of the movable plate. Multiple sets of compression springs are installed between the rear side of the movable plate and the inner wall of the housing.

This can be done without the aid of tools, greatly enhancing the convenience of use. Attached Figure Description
