Abstract: A battery includes a battery cell and a terminal post. The first casing includes a first arc sidewall and a flat sidewall connected to the first arc sidewall and the first sidewall. The terminal post is disposed on the flat sidewall. Instead of disposing the terminal post on top of the battery, increased thickness of the battery due to the terminal post is avoided in the present disclosure. The internal space of an electrode device can be fully utilized. In addition, it can prevent the terminal post from occupying the top of the battery and decreasing the number of the electrode plates. Thus, the present disclosure can avoid the reduce of the number of the electrode plates and increase the energy density of the battery.

Abstract: The present disclosure provides an extensible stable clamping device. A chuck subassembly of the extensible stable clamping device includes two clamping jaw bodies and two clamping jaw heads. The two clamping jaw bodies are curved towards the inner sides and are symmetrically disposed; after the two clamping jaw bodies are closed, a clamping gap is formed between the clamping jaw bodies; the clamping gap can accommodate a clamped object; each clamping jaw head is located at a top of the clamping jaw body and extends a distance in a direction where the clamping jaw body extends out to form a plate shape; and after the two clamping jaw bodies are closed, the two clamping jaw heads are attached to each other to improve the clamping stability.

Abstract: A housing includes a first housing and a second housing. The second housing is provided with at least one protrusion, and the first housing includes a bottom wall and a side wall. The side wall is disposed on a peripheral edge of the bottom wall to form an accommodating space together with the bottom wall. The second housing is disposed on a side of the side wall away from the bottom wall, and the at least one protrusion is accommodated in the accommodating space and comes in contact with an inner surface of the side wall.

Abstract: The present disclosure provides a retractable pickup device. A chuck subassembly of the retractable pickup device includes: a control handle subassembly, a driving subassembly that is in driving connection with the control handle subassembly, and a chuck subassembly that is in driving connection with the driving subassembly. The control handle subassembly drives the chuck subassembly to be closed and opened through the driving subassembly, so as to achieve picking and placement of an object. The present disclosure has the beneficial effects that in the actual operation, the control handle subassembly is operated to drive the chuck subassembly to be closed and opened through the driving subassembly, so as to achieve picking and placement of the object. Therefore, the retractable pickup device after the improvement is simpler in both structure and operation, which further improves the operation experience of a user.

Abstract: A method of using a mobile terminal to implement cloud searching is provided. The method includes receiving, by the mobile terminal, searching conditions inputted by a user; executing, by the mobile terminal, local searching; and detecting whether networking is executed If networking is executed, the method includes detecting, by the mobile terminal, whether the local stores user account information; and connecting to a cloud server when the local of the mobile terminal stores the user account information. If networking is not executed, the method includes returning local searching results. The method further includes transmitting, by the mobile terminal, the searching conditions to the cloud server; and executing, by the cloud server, cloud searching according to the searching conditions; and returning searching results to the mobile terminal.
