Figure 5 As shown, a slot is provided on the placement plate 2, which allows the movable plate 9 to move a short distance to the left. The outer wall of the slider 4 is elastically connected to the limit block 11 through a positioning spring 10. The right end of the limit block 11 is inclined. When the inclined surface is squeezed, the limit block 11 will slide along the inner wall of the slider 4. An adjustment mechanism is provided on the top of the placement plate 2, and a connecting component is provided on the side wall of the placement plate 2.

[0037] Reference Figure 2 、 Figure 6 and Figure 7The connecting assembly includes an insert 15, which is fixedly connected to the side wall of the placement plate 2. The outer wall of the insert 15 is plugged with a positioning plate 16. The positioning plate 16 matches the insert 15, allowing the insert 15 to be plugged with it to initially position the entire placement plate 2. The inner wall of the positioning plate 16 is penetrated and slidably connected with a wedge 18. The wedge 18 is inclined. When the inclined surface is squeezed, the wedge 18 slides along the inner wall of the positioning plate 16. The right end of the wedge 18 is supported by a movable spring 17. It is elastically connected to the testing machine 1, and the right end of the wedge block 18 is fixedly connected to one end of the movable spring 17. When the wedge block 18 moves to the right, it compresses the movable spring 17. When resetting, the elastic force of the movable spring 17 is used to reset the wedge block 18. The other end of the movable spring 17 is fixedly connected to the inner wall of the right end of the testing machine 1. The wedge block 18 is inserted into the side wall of the insertion block 15. The insertion block 15 is provided with an opening corresponding to the wedge block 18, and the positioning plate 16 is fixedly connected to the inner wall of the testing machine 1.

[0038] Reference Figure 2-Figure 4 When the cam 4 is in the state of being moved down, the cam 4 is in the state of being moved down, and the cam 4 is in the state of being moved down, and the cam 4 is in the state of being moved down, and the cam 4 is in the state of being moved down, and the cam 4 is in the state of being moved down, and the cam 4 is in the state of being moved down, and the cam 4 is in the state of being moved down, and the cam 4 is in the state of being moved down, and the cam 4 is in the state of being moved down.

[0039] Reference Figure 4-Figure 5The adjustment mechanism includes a top frame 12, which is fixedly connected to the top of the placement plate 2. The inner wall of the top frame 12 is penetrated and threadedly connected with a threaded rod 13. The top of the top frame 12 is provided with a pattern corresponding to the threaded rod 13, which allows the threaded rod 13 to move along the inner wall of the top frame 12. The right end of the threaded rod 13 is rotatably connected to a slide plate 14, which is slidably connected to the inner wall of the top frame 12. A slot is provided on the top frame 12 to meet the lateral movement of the movable plate 9 in the slot. The right end of the slide plate 14 It contacts the left end of the movable plate 9, and the outer wall of the slider 4 is fixedly connected to one end of the positioning spring 10. When the limit block 11 moves outward, the positioning spring 10 will be stretched. When resetting, the elastic force of the positioning spring 10 is used to reset the limit block 11. The other end of the positioning spring 10 is fixedly connected to the inner side wall of the limit block 11. The limit block 11 is inserted into the outer wall of the support column 5. A notch corresponding to the limit block 11 is opened on the support column 5, so that the limit block 11 can be inserted into it to limit the slider 4 in one direction.

[0040] Working principle: First, when multiple flat plates need to be clamped and fixed for testing at the same time, just place the flat plates one by one horizontally from the inside to the outside in the arc of the movable plate 9, then move the slider 4 downward and compress the return spring 3, let the slider 4 move downward with the hinge rod 6, let the other end of the hinge rod 6 push the connecting plate 7 and the fixed plate 8 to move to the left, let the arc of the fixed plate 8 contact and cooperate with the movable plate 9 to fix the flat plate, when the slider 4 moves downward, the outer wall notch of the support column 5 will squeeze the inclined surface of the limit block 11, let the limit block 11 move outward and stretch the positioning spring 10, let the limit block 11 separate from the notch of the support column 5, when the limit block 11 coincides with the next outer wall notch of the support column 5, use the reverse elastic force of the positioning spring 10 to reset the limit block 11, and let the limit block 11 be plugged into the outer wall notch of the support column 5.

[0041] When it is necessary to release the limit of a single plate, it is only necessary to rotate the threaded rod 13 counterclockwise to move the threaded rod 13 with the slide 14 to the right, so that the movable plate 9 has enough space to move to the left, so that the arc of the movable plate 9 can be separated from the plate, and the limit of the single plate can be released and tested separately.

[0042] When multiple tablets need to be released from the limit at the same time, just pull the limit block 11 outward and stretch the positioning spring 10 to separate the limit block 11 from the notch of the support column 5. Then move the slider 4 upward with the hinge rod 6 and use the reverse elastic force of the reset spring 3 to move to the initial state. The hinge rod 6 will bring the connecting plate 7 and the fixed plate 8 to reset to the right. Finally, release the limit block 11 and use the reverse elastic force of the positioning spring 10 to reset the limit block 11.

[0043] When it is necessary to move the two sets of placement plates 2 out of the test machine 1 to test larger electronic equipment, it is only necessary to push the wedge 18 to the right and compress the movable spring 17 to separate the wedge 18 and the opening of the plug block 15. Then, the plug block 15 on the placement plate 2 is slowly moved out from the inner wall of the positioning plate 16, and finally, the wedge 18 is released and the reverse elastic force of the movable spring 17 is used to bring the wedge 18 back to the left. When it is necessary to install the two sets of placement plates 2 into the test machine 1, it is only necessary to insert the plug block 15 into the positioning plate 16 and use the side wall of the plug block 15 to squeeze the inclined surface of the wedge 18, so that the wedge 18 moves to the right and compresses the movable spring 17. When the wedge 18 coincides with the opening of the plug block 15, the reverse elastic force of the movable spring 17 is used to bring the wedge 18 back to its original position, so that the wedge 18 is inserted into the slot of the plug block 15 to limit the plug block 15 in one direction. The test space inside the test machine 1 can be adjusted according to actual conditions.
