Problems solved by technology

For example: in the current small green mandarin tea packaging process, people can place each small green mandarin in the placement slot of the packaging box. In the back, because the notch is narrow and deep, it is often inconvenient for users to take it out, so it is necessary to design a supporting device that can lift it out from the placement slot of the packaging box

Abstract

The invention discloses an extensible self-locking device and a product bracket using the same. The extensible self-locking device comprises an extensible top joint, an extensible bottom joint, a rotary cylinder, a middle bearing spring and at least one middle extensible joint, wherein the extensible top joint, extensible middle joints and the extensible bottom joint are movably connected from topto bottom, the rotary cylinder is rotatably installed in the extensible bottom joint, the middle bearing spring is installed between the extensible top joint and the extensible bottom joint and penetrates through all the extensible middle joints and the rotary cylinder, the bottom of the extensible top joint is provided with multiple V-shaped driving teeth and driving clamp blocks, the outer wallof the lower end of the rotary cylinder is provided with multiple lower driving oblique blocks, and the outer wall of the upper end of the rotary cylinder is provided with multiple groups of upper-end driving oblique blocks consisting of first upper driving oblique blocks and second upper driving oblique blocks. The extensible self-locking device is simple in structure and stable and reliable inoperation, has extensible and self-locking functions, can support a product through pressing and then achieve retraction self-locking through pressing, is very simple and convenient to operate, convenient for a user to use and wide in application range.

Description

technical field [0001] The invention relates to the technical field of supporting devices, more specifically, to a retractable self-locking device and a product bracket using the device. Background technique [0002] In some occasions, the product needs to be held up by the supporting device so that the user can take it easily. For example: in the current small green mandarin tea packaging process, people can place each small green mandarin in the placement slot of the packaging box. In the back, because the notch is narrow and deep, it is often inconvenient for users to take it out, so it is necessary to design a supporting device that can lift it out from the placement groove of the packaging box. Of course, in the process of using other products, in order to facilitate the user's operation, it is also necessary to design a product supporting device. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects in th...
