Problems solved by technology

However, with this traditional fixing method, the head of the screw and the nut expose the surface of the first mounting part and the surface of the second mounting part respectively, which increases the thickness of the product
Moreover, when the fixing hole on one of the mounting parts is not a through hole, this traditional fixing method cannot be used to achieve fixing

Abstract

The invention relates to a fixing device used for fixing a first mounting piece on a second mounting piece. The fixing device comprises a first fixing piece and a second fixing piece, wherein the first fixing piece is provided with two separate clamping parts, and the inner walls of the two clamping parts are provided with inner threads; the outer wall of the second fixing piece is provided with an outer thread; the second fixing piece is accommodated between the two clamping parts; and the outer thread of the second fixing piece is engaged with the inner threads of the two clamping parts of the first fixing piece, and the two clamping parts are outwards expanded. The fixing device has simple structure and is suitable for fixing different types of mounting pieces.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device which is easy to install and disassemble. Background technique [0002] The fixing device is usually used to connect a first mounting part and a second mounting part together, wherein each mounting part is provided with a mounting hole, and the fixing part passes through the mounting holes of the two mounting parts to lock the mounting parts together . The traditional structure for fixing two mounting parts is to cooperate with a screw and a nut. The screw usually has a head larger than the mounting hole on the first mounting part and a screw rod with an external thread at the end. The periphery of the nut is larger than the mounting hole on the second mounting part, and the nut has an internal thread capable of engaging with the external thread of the screw rod. During installation, the first mounting part is attached to the second mounting part, and the mounting holes on th...
