Embodiment

Shown in Fig. 3,4, the utility model is used for the structure of detector electronics anchor clamps, comprises a pedestal 20, and pedestal 20 is connected with a rotating spanner 22 through a rotating shaft 21.The load substrate 23 that can move around is installed on the pedestal 20 of these rotating shaft 21 belows by at least one qualification axle 30 with elastic component 31, and load substrate 23 can be moved along described qualification axle 30; And this elastic component 31 makes load substrate 23 get back to the position (this part will be narrated hereinafter) of first end from stressed position.

An opening 24 is arranged near the middle section of load substrate 23, porose 25 on the opening 24, in order to a pivot pin 26 to be installed; A cam 40 is arranged in this opening 24, and this cam 40 is installed in this rotating shaft 21 with eccentric form, and rotates with spanner 22.In a preferred embodiment, cam 40 comprise one on eccentric position turn to rail 41 (displacement guiding can be docile and obedient as shown clockwise gradually row depart from, otherwise also can with counterclockwise gradually row depart from) and turn to a positioning section 42 of rail 41 rear ends; And make above-mentioned pivot pin 26 relative motion in this turns to rail 41, force load substrate 23 to move with the rotation of cam 40.

One has the follower plate 50 that probe portion 51 connects winding displacement 52, is connected this load substrate 23 1 ends, moves with load substrate 23; With so that probe portion 51 contact or do not contact this electronic package that is placed in a desired location on the worktable 60, circuit board or its similar object 70.

See also Fig. 3, Fig. 5, described this load substrate 23 and be positioned at initial position, probe portion 51 not with the situation of this electronic package, circuit board or its similar object 70 contact detection.When rotating, operation spanner 22 top or Fig. 6 direction of arrow in figure (also can make the rail 41 that turns to of cam 40 be made as reverse direction, when spanner 22 will be pulled downwards this moment, produce the action that compacting load substrate 23 descends), cam 40 rotates with spanner 22, and makes this pivot pin 26 seal displacement mutually in turning to rail 41; Therefore, pivot pin 26 forces the stressed position of load substrate 23 below in figure to be moved, and drives probe portion this electronic package of 51 contact detection, circuit board or its similar object 70, as shown in Figure 6 and Figure 7.
