Abstract: The present invention relates to the technical field of photographic apparatuses, and in particular, to a locking assembly, a driving-type locking mechanism, a telescopic supporting leg, and a tripod. The locking assembly includes a fixing base and a rotating shaft member, an abutting component is fixedly sleeved on a periphery of the rotating shaft member, and an elastic component and a movable component are disposed on the periphery of the rotating shaft member. The driving-type locking mechanism includes a driving component and the locking assembly. The telescopic supporting leg includes the driving-type locking mechanism, an upper sleeve, and a lower sleeve. The tripod includes a tripod base, an operating component, and three telescopic supporting legs. According to the present invention, a transmission member is not needed to provide locking force or locking torque for the locking assembly.

Abstract: A tripod, comprising angle snap-fit structures (32); rotating members (33), each of the rotating member (33) having one end rotatably connected to each angle snap-fit structure, and the other end connected to each support leg (1) of the tripod; angle control members (34) which are matched and snap-fitted with the angle snap-fit structures so as to lock the corresponding angle of the rotating members rotating relative to the angle snap-fit structures; support legs, each of the support legs comprising two or more leg sections (1a, 1b, 1c) and expandable assemblies (2) mounted on the second leg section (1b) and the third leg section (1c), wherein each leg section can axially move relative to one or more of other leg sections, and the expandable assemblies can perform position locking and position releasing by means of expansion and contraction. The structure can implement quick adjustment of the angle and length of the support legs.

Abstract: The invention discloses a method and a device for constructing a SQL statement based on reinforcement learning, wherein the method includes: initializing an actor-critic network parameter; acquiring a sequence pair of natural language and real SQL statement from a data set; inputting a natural language sequence into an actor network encoder, and inputting a real SQL sequence into a critic network encoder; using an encoded hidden state as an initialized hidden state of a corresponding decoder; gradually predicting, by an actor network decoder, a SQL statement action, and inputting the SQL statement action to a critic network decoder and an environment to obtain a corresponding reward; and using a gradient descent algorithm to update the network parameters, and obtaining a constructing model of the natural language to the SQL statement after repeated iteration training.
