In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

In an embodiment of the applanation mechanism shown in fig. 1, a protrusion 3 extends along the axial direction of the body 1, and the protrusion 3 is integrally formed with the body 1. A clearance structure 2 for accommodating burrs is arranged between the protruding part 3 and the body 1.

The body 1 sets up a plurality of stands along circumference equidistant, and wherein, keep away the shaping of empty structure 2 between stand and body 1, a plurality of recesses, protruding portion 3 for the interval sets up are circular reference column. The positioning column is provided with a frustum 4 at one end far away from the body 1, and a guide inclined plane is formed on the side surface of the frustum 4. The cross-sectional area of the end surface of the frustum 4 far away from the body 1 is smaller than that of the other end surface close to the body 1. Set up frustum 4 on the reference column in order to be used for with treat that connecting piece 6 is connected, treat that connecting piece 6 is last to be equipped with the through-hole 5 with the reference column tight fit.

The flatting mechanism is made of elastic materials and can be made of rubber or flexible plastics.

One embodiment of a lay flat assembly as shown in fig. 2 comprises the lay flat mechanism and the part to be connected 6 connected with the projection 2 of the lay flat mechanism. Specifically, treat that connecting piece 6 is the PCB board, be equipped with on the PCB board and be used for the through-hole with reference column tight fit.

In the specific implementation process, burrs which are difficult to identify by naked eyes can appear in the inner hole of the PCB after the PCB is subjected to engraving and milling. When the PCB is connected with the body 1, the frustum 4 of the positioning column is firstly contacted with the through hole 5 of the PCB, and the frustum 4 plays a role in guiding when being contacted with the through hole 5 of the PCB. Under the guide effect, through-hole 5 of PCB board is to reference column direction motion, and 5 inner walls of through-hole and reference column outer wall can take place to wipe and bump this moment, and remaining burr drops towards body 1 direction on the inner wall and directly enters into and keeps away empty structure 2, and it is flat to paste with the stand surface until the surface of PCB board. Annular recess form keep away empty structure 2 has held the burr that drops because of wiping of PCB board through-hole 5 and reference column bumps, has avoided the burr directly to fall on the surface of pasting flat mechanism and influence the roughness of installing the PCB board on body 1 to guarantee the switching electrical property of PCB board, effectively improve product overall quality.
