The variable-speed gear set comprises variable-speed driving gears, variable-speed driven gears, driving variable-speed shifting fork rods and driven variable-speed shifting fork rods. The number of the driving variable-speed shifting fork rods is consistent with that of the driving gears. The number of the driven variable-speed shifting fork rods is consistent with that of the driven gears. A driving inserting hole is formed in the variable-speed driving gear, and a driven inserting groove is formed in the variable-speed driven gear.

The present invention provides an electronic device, comprising: a housing, a power mechanism, a rotating part, a sliding part and a driven part, and the power mechanism, the rotating part and the sliding part are all arranged in the housing; the The first end of the rotating part is connected with the power mechanism, and the surface of the rotating part is provided with a spiral slide groove; the first end of the sliding part is connected with the driven part, and the sliding part is provided with a The spiral chute is matched with the first slider; wherein, the power mechanism drives the rotating part to rotate, and drives the first slider to slide in the helical chute, so that the driven part It has a first state protruding from the housing and a second state being accommodated in the housing. In the embodiment of the present invention, the rotating part and the sliding part work together to achieve the purpose of transmission, and the rotating part and the sliding part have a better effect of resisting external impact force, thereby enhancing the reliability of driving the driven part.

The invention discloses a data transmission method and device. Wherein, the method includes: receiving the first request sent by the first target object; sending a first response message to the first target object in response to the first request, and transmitting the first target data to the second target object through the network, and the first response message Used to simulate the response message sent by the second target object after receiving the first target data; receive the second request sent by the first target object in response to the first response message, and the second request is used to request transmission to the second target object through the network Second target data for remote debugging; sending a second response message to the first target object in response to the second request, and transmitting the second target data to the second target object through the network, wherein the second response message is used to simulate the first target object The response message sent by the second target object after receiving the second target data. The invention solves the technical problem of low transmission efficiency of data transmission in the related art.

Provided by the present disclosure are a method and apparatus for transmitting diversity in a multi-antenna communication system, the method comprising: determining a pilot frequency sequence to be transmitted of each antenna port; mapping the pilot frequency sequence to be transmitted of each antenna port respectively to a resource element (RE) comprised in a pilot frequency symbol of a target subframe, so that the N antenna ports multiplex the pilot frequency symbol of the target subframe; on the target subframe, each antenna port respectively transmitting the pilot frequency sequence to be transmitted on the RE of the pilot frequency symbol to which the pilot frequency sequence to be transmitted of the antenna port is mapped.

The invention relates to the field of accessories for door windows, in particular to an aluminum alloy handle for door windows. The aluminum alloy handle is characterized in that a shaft sleeve and a handle seat of the aluminum alloy handle are assembled together, and a handle is penetratingly arranged in a hole of the shaft sleeve; springs are placed in a lining plate, then balls are placed in holes of the springs, the springs and the lining plate are assembled together and then are placed into the handle seat, then a gasket is assembled on the lining plate and is assembled on the other side of the handle seat, a gear is placed on the gasket, the handle seat and the handle are fixed to each other by the aid of a cross recessed countersunk head screw, a shift fork is placed into the handle seat and is meshed with the gear, mounting holes which are perforated through the handle seat are formed in the upper surface of the handle seat, threaded holes are formed in the lower surface of the handle seat, a bottom cover is fastened in the holes of the handle seat, and the mounting holes and the threaded holes can be exposed via the bottom cover. Assorted fastening covers are arranged on the mounting holes. The aluminum alloy handle has the advantages that the aluminum alloy handle not only can be applied to outward-opening windows, but also can be applied to inward-opening windows, only a large quantity of handles with identical specifications need to be prepared when assembled, and cannot be mixed up, and accordingly the practical performance of the aluminum alloy handle is improved.

Both are provided with a matching second grinding mechanism. The invention has a simple structure, and is used for multi-section cutting of the copper pipe to improve the cutting efficiency of the copper pipe.

The present invention relates to the field of computer communication, in particular to a data structure, a transmission method and a data terminal device. The terminal device on a mobile carrier realizes information reception, processing, storage and transmission, and provides time-sensitive distributed production sites. A low-cost, high-efficiency information transfer method, and in animal and plant conservation, provides an efficient collection method for relevant information. In the process of moving the carrier between the decentralized production sites, the data terminal on the mobile carrier realizes the transmission of data between the terminal devices on the mobile carrier through broadcasting, further achieving the purpose of information transmission between the decentralized production sites; in addition, During the transfer process, rules will be judged on the transfer content, and the transferred information content will be cleared in a timely manner to avoid the waste of resources such as storage, judgment and calculation due to the accumulation of a large amount of transfer information.
