A control method includes, in response to detecting that an external device is in a target positional relationship with an electronic device, adjusting a working parameter of a supporting assembly of the electronic device, so that the supporting assembly is in a normal working state. In the normal working state, the supporting assembly is able to support the electronic device in different postures.

Control method, apparatus, and electronic device

A support device includes a support structure, a carrier assembly, and an elastic assembly. The carrier assembly is configured to support a display device. The carrier assembly ascends and descends relative to the support structure. The elastic assembly is connected to the support structure and the carrier assembly and provides different support forces to the carrier assembly to support display devices of different weights.

Support device and electronic apparatus

A downhole power drilling tool includes a flow distribution shaft, an outer pipe and a multi-stage eccentric gear driving mechanism which are coaxially arranged, the flow distribution shaft is suspended and supported in the outer pipe by the multi-stage eccentric gear driving mechanism.

A full-metal dynamic-sealed concentrically-centered downhole displacement motor includes an outer tube, a stator fixed in the outer tube, a rotor rotatably connected in the stator, and a flow distribution shaft suspended in the rotor. When the rotor rotates, the plurality of circulation ports is alternately communicated with the flow distribution holes, and an accommodation space for flowing the drilling fluid is formed among the plurality of rotor copper rods; each of the circulation ports has a notch on the side of the rotor copper rod that is in communication with the accommodation space; the stator is provided with pressure relief ports for allowing the annular chamber and the accommodation space to communicate with each other, and the flow distribution hole and the pressure relief port are circumferentially arranged in a staggered manner.
