[0017] Please refer to the following: Figures 1-3 This utility model discloses a spring clip mounting fixture for a semiconductor heat sink, comprising: a fixture base 1, a vertical plate 2 fixedly connected to one side of the top of the fixture base 1, a fixing plate 3 fixedly connected to the upper end of the vertical plate 2 by screws, a limiting sleeve 4 fixedly welded to one end of the lower end of the fixing plate 3, a pressure post 5 longitudinally fitted and slidably sleeved inside the limiting sleeve 4, a limiting ring 6 fixedly connected to the outer side of the upper end of the pressure post 5 above the limiting sleeve 4, a return spring 7 sleeved between the pressure post 5 and the limiting sleeve 4 and the limiting ring 6, a connecting piece 18 connected to the top of the pressure post 5 by a shaft, a pressing handle 8 connected to the top of the connecting piece 18 by a shaft, and a shaft seat 9 connected to the end of the pressing handle 8 near the connecting piece 18 by a shaft.
[0018] Among them, the tooling base 1 has a bottom column 11 on one side of the top pressure column 5. The bottom column 11 has a rivet placement groove 12 in the middle of the top. The bottom end of the pressure column 5 is directly opposite the bottom column 11. The inner diameter of the limiting sleeve 4 is the same as the outer diameter of the pressure column 5. Thus, the limiting sleeve 4 ensures that the pressure column 5 moves vertically and stably up and down. The shaft seat 9 is fixedly welded to one side of the upper end of the fixed plate 3. The pressing handle 8 has a bent structure. The end of the pressing handle 8 away from the shaft seat 9 is fixedly sleeved with a rubber sleeve 10. The rubber sleeve 10 makes it easy for personnel to hold the pressing handle 8 for use.
[0019] Combination Figure 3 As shown, a rivet head 15 is placed at the top of the bottom post 11 through a rivet placement groove 12. A rivet body 14 is riveted to the inside of the upper end of the rivet head 15. A washer 16 is sleeved on one end of the rivet body 14, and the washer 16 limits the spring body 17. The rivet body 14 is connected to the radiator mounting base 13 through the radiator mounting base 13. The spring body 17 is sleeved between the rivet body 14 and the washer 16.
[0020] Combination Figure 1As shown, when using this utility model, simply place the rivet head 15 in the rivet placement groove 12 on the base post 11, then pass the rivet body 14 through the radiator mounting base 13, and then pass the spring body 17 and the washer 16 through the rivet body 14 in sequence. Next, align the end of the rivet body 14 with the rivet head 15 (at this time, hold the radiator mounting base 13), then manually pull down the pressing handle 8, and then the pressing handle 8 presses down the pressing post 5 through the connecting piece 18, and then the pressing post 5 presses down to rivet the rivet body 14 and the rivet head 15. After riveting, release the pressing handle 8, and then push the limiting ring 6 under the upward elastic force of the return spring 7, and then the limiting ring 6 lifts the pressing post 5 to reset.
