[0024] One end of the positioning frame 34 away from the movable plate 32 extends to the inner cavity of the positioning hole 36 and is movably connected to the inner cavity of the positioning hole 36 .
[0025] like Figure 1-3As shown, by placing the transistors in the placement grooves on the top of the fixing seat 1, and the number of placement grooves is six, six transistors can be placed at the same time, and by pulling the positioning frame 34 to move to one side, the positioning frame 34 will cause the movable disk 32 and the spring 33 to move to one side, and then the spring 33 is stretched to produce deformation, and at the same time the connecting seat 2 drives the connecting block 35 to move to one side around the hinge, so that the connecting block 35 is directly above the fixing block 31, and the positioning frame 34 can be reset by the reset elastic force of the spring 33, and the positioning frame 34 enters the inner cavity of the positioning hole 36, and then the connecting block 35 and the connecting seat 2 can be positioned, so that the connecting seat 2 can position the six transistors.
[0026] Example 2
[0027] Reference Figure 1 and 2 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.
[0028] In this embodiment, the inner cavities of the placement grooves at the tops of the fixing seat 1 and the connecting seat 2 are fixedly connected with the soft pads 21, and the side of the soft pads 21 away from the inner wall of the placement groove is in contact with the transistor.
[0029] A limiting hole 351 is formed at the top of the connecting block 35 . A limiting rod 311 is fixedly connected to the top of the fixing block 31 . The top of the limiting rod 311 extends to the inner cavity of the limiting hole 351 and is movably connected to the inner cavity of the limiting hole 351 .
[0030] like Figure 1 and 2 As shown, the transistor can be protected by the soft pad 21 to prevent the transistor from being worn when positioned. At the same time, when the connecting seat 2 drives the connecting block 35 to move to just above the fixed block 31, the limiting rod 311 will enter the inner cavity of the limiting hole 351, thereby positioning the connecting block 35.
[0031] Example 3
[0032] Reference Figure 1 and 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.
[0033] In this embodiment, the bottom of the fixing seat 1 is fixedly connected to the support 11 , the bottom of the support 11 is fixedly connected to the connecting plate 12 , and the top of the connecting plate 12 is movably connected to bolts.

[0036] When in use, first place the transistor in the placement slot of the fixing seat 1. There are six placement slots, and then the six placement slots can be placed at the same time. After placement, pull the positioning frame 34 to move to one side, and the positioning frame 34 will drive the movable disk 32 to move to one side. The movable disk 32 drives the spring 33 to move to one side, so that the spring 33 is stretched and deformed. At the same time, pull the connecting seat 2, and the connecting seat 2 drives the connecting block 35 to move to one side around the hinge, so that the connecting block 35 is directly above the fixed block 31. Then release the positioning frame 34, and the positioning frame 34 can be reset by the reset elastic force of the spring 33. The positioning frame 34 will gradually enter the inner cavity of the positioning hole 36, and then the connecting block 35 and the connecting seat 2 can be positioned.
