Detailed Description

The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.

Examples are given. A PCB fixing device for a small-sized chip mounter is composed of a base plate 1, a plurality of fixing seat groups 2 arranged on the base plate 1, a fixing shaft 3 arranged at the lower end of the fixing shaft 3, a rotating arm 4 rotatably connected to the fixing shaft 3 and including a rotating cylinder 401, a limiting plate 301 arranged at the outer side of the fixing shaft 3 and arranged at the bottom of the rotating cylinder 401, a locking cover 5 connected to the fixing shaft 3 and arranged at the top of the rotating cylinder 401, an arm body 402 arranged at one side of the outer wall of the rotating cylinder 401, a wiring chute 403 and a base body chute 404 arranged at both sides of the arm body 402 and communicated with each other via a strip hole 405, a plurality of wire mounting seats 6 arranged on the wiring chute 403, a fixing seat 7 arranged on the base body chute 404, and a guide plate 701 arranged at the inner side of the fixing seat 7 and matched with the chute base body 404, the two ends of the fixing seat 7 are provided with electromagnetic locks 8, and the top of the fixing seat 7 is provided with a mounting hole.
