In a shift device, rotational movement of a lever in a left and right direction is restricted by control of a motor. Rotational movement of the lever in a front and rear direction is also restricted by control of the motor. Therefore, rotational movements of the lever in the left and right direction and in the front and rear direction can be restricted by control of the single motor. Thus, structure of the restricting mechanism can be simplified.

A joystick including a main housing with a first control surface and a second control surface. A ball rotationally engages the first control surface. A shaft has a first end that releasably engages the ball. A shoe rotationally engages the second control surface. A main spring has a first end for pressing the shoe against the second control surface. A center lock housing engages a second end of the main spring and houses a slider and a lock spring. The slider selectively permits and prevents movement of the shoe along the shaft. The lock spring presses the slider into a desired default position. A knob releasably engages the second end of the shaft. A boot covers portions of the joystick.

A rotational positioning mechanism includes a base, a rotational shaft, a rotational plate, at least two first switches and a positioning assembly. The rotational shaft is pivoted to the base. The rotational plate is connected to the rotational shaft and is configured to rotate relative to the base along with the rotational shaft. The rotational plate has at least two first positioning portions. The two first switches are respectively disposed at the two first positioning portions. The positioning assembly is disposed at the base, and comprises a positioning component configured to form a structural interference with any one of the first positioning portions or remove the structural interference. After the positioning component forms the structural interference with any one of the first positioning portions, the positioning component abuts against the corresponding first switch, and the degree of rotational freedom of the rotational plate and the rotational shaft are restricted.

A remote controller comprising a shifter lever structure, a controller, and a signal emission device electrically coupled to the controller. The shifter lever structure includes a base, a press key movably connected to the base, a shifter lever arranged surrounding the press key and movably connected to the base, and a sensor coupled to the press key and the shifter lever. The sensor is configured to obtain moving state information about the press key and the shifter lever. The sensor includes at least one of an angle sensor, an angular displacement sensor, an angular velocity sensor, an angular acceleration sensor, a torque sensor, a distance sensor, a linear displacement sensor, a linear velocity sensor, a linear acceleration sensor, or a pressure sensor. The controller is configured to receive the moving state information from the sensor and emit a control signal corresponding to the information via the signal emission device.

An apparatus with two anchors including a housing, a movable element, and a rotary element is provided. The housing includes a first expansion unit, a second expansion unit, and a linkage. First alignment structures are disposed in the movable element and anti-rotation structures are disposed in the linkage. When the movable element and the rotary element enter the housing from two ends and are coupled along an axis, the movable element and the rotary element can approach each other to expand the first expansion unit and the second expansion unit to fonn two anchors. The apparatus :with two anchors secures a sensor in a variety of environments such as walls or machines. When the apparatus with two anchors fixes a sensor in a hole of a stamping machine, the impact force does not cause stress concentration on the sensor so as to improve the reliability of the sensor.
