A tension lock comprises a first base and a second base which are matched with each other. A lock hook having a unciform head and an annular tail is arranged inside the first base, an eccentric cam having an eccentric shaft is arranged inside the annular tail of the lock hook, a spring enabling the eccentric cam and the lock hook to be interlocked with each other is arranged between the eccentric cam and the inner wall of the lock hook, the shaft end of the eccentric shaft is internally hexagonal, the lock hook is movably arranged inside the first base through the eccentric shaft of the eccentric cam, and correspondingly a fixed shaft is arranged inside the second base. The invention is characterized in that: the eccentric cam and the eccentric shaft are both made of steel material, and the eccentric shaft travels into an eccentric cam connecting hole and is welded securely in the connecting hole. The invention is applicable to tension locks with greater locking strength, reliable operation, long service life and the cam which is not easy to break.

The invention relates to a mobile hard disc, which comprises a shell, an opening positioned on the shell, a moveable USB male which is led out from the inside of the shell through the opening, a hard disc accommodated in the shell and a flexible PCB electrically connected with the hard disc, wherein the flexible PCB comprises a hard disc control chip and a circuit and is provided with a slender extension part taken as a USB data wire connected with the USB male; and the USB data wire is bent and accommodated in the shell and is pulled out or pushed in the shell along with the USB male through the opening. The mobile hard disc has the advantages that: firstly, the USB male has a moveable structure and is accommodated in the shell, and in use, the USB male is pushed out from the opening and is connected through the flexible USB data wire which is not easy to break off and damage; secondly, the mobile hard disc is designed by the flexible PCB so as to facilitate the lightness and thinness; thirdly, the mobile hard disc is used for the integrated design of the flexible PCB controlled by the hard disc and the USB data wire so as to improve the production efficiency; and finally, the USB male adopts the unshielded design so as to save the space.

The invention provides an uninterrupted full-automatic plywood hot press production line. According to thee uninterrupted full-automatic plywood hot press production line, the structural form of a traditional plywood hot press is broken through, in the actual working process, under the control of a master controller, a glue brushing production line section is used for brushing glue on template blanks to form template blocks subjected to glue brushing then and conveying the template blocks subjected to glue brushing to a hot press forming production line section, a supply production line section is used for conveying interlayer and the uppermost-layer template blank to the hot press forming production line section so that the uppermost-layer template blank can be arranged above the corresponding number of the template blocks subjected to glue brushing in a cushioning mode to serve as a surface layer, the interlayer can be arranged above the corresponding uppermost-layer template blank in a cushioning mode to separate the uppermost-layer template blank located at the upper portion from the several template blocks subjected to glue brushing and separate the uppermost-layer template blank located at the lower portion and the several template blocks subjected to glue brushing, finally, the hot press forming production line section is used for performing hot press forming, and multiple plywood can be formed at a time. According to the uninterrupted full-automatic plywood hot press production line, uninterrupted, continuous and smooth hot press forming can be performed on the template blanks, the mechanical degree is high, and the strength of the finished-product plywood is higher.
