Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is done concrete introduction.

Referring to figs. 1 through Fig. 4, PCB measurement jig of the present utility model comprises: casing 1, needle plate 2, support plate 3, cover plate 4 and driving mechanism 5.Casing 1 is horizontally disposed with, and its inside has a cavity; Needle plate 2, support plate 3, cover plate 4 set gradually from bottom to up, and all are arranged at the top of casing 1, and wherein, support plate 3 is fixedly connected with casing 1, and cover plate 4 is rotationally connected by coupling shaft with casing 1.

Driving mechanism 5 in the utility model is used for driving needle plate 2 and does vertical to-and-fro movement, and as a kind of preferred scheme, driving mechanism 5 comprises: cam 51, handle 52, and rotating shaft 53.Wherein, cam 51 be positioned at casing 1 cavity, be arranged at the below of needle plate 2, and contact with needle plate 2; Handle 52 be positioned at casing 1 the outside, be fixedly connected with cam 51, junction both is formed with a reception hole; One end of rotating shaft 53 is fixedly connected with casing 1, and the other end inserts in above-mentioned reception hole, can realize that cam 51 53 rotates around the shaft, vertically moves reciprocatingly thereby drive needle plate 2 thereby move handle 52.

As a kind of preferred scheme, the angle between cam 51 and handle 52≤90 degree can facilitate and manually move handle 52.

As a kind of preferred scheme, cover plate 4 rotates opening and closing around coupling shaft and realizes by barb handle 6.Concrete, barb handle 6 is arranged at a side that is connected with casing 1 of cover plate 4, and utilize its hook end directly or indirectly with cover plate 4 around coupling shaft jack-up, thereby realize the unlatching of cover plate 4; After unclamping barb handle 6, cover plate 4 is because gravity falls, and lid is pressed on support plate 3, or lid is pressed on PCB to be tested.
