The rotation of the threaded sleeve drives the telescopic rod to move. Due to the stepless expansion and contraction performance of the thread, the spacing between the two splints can be more precisely adjusted according to the length of the electronic device, the electronic device is clamped, and the electronic device of the various lengths of the splint is improved. Adaptation performance; the clamping plate is in the clamping state, the telescopic rod pushes the threaded sleeve against the rotating shaft, so that the threaded sleeve is integrated with the rotating shaft, so in the clamped state, the rotating shaft rotates together with the threaded sleeve and the telescopic rod.

The axial movement of one end of the threaded sleeve is constrained, so that when the threaded sleeve rotates, the telescopic rod undergoes relative axial movement, which can be manually grasped and the rotation of the telescopic rod is restricted, so that the telescopic rod moves axially.

Preferably, the baffle assembly comprises a retaining ring fixed to the rotating shaft and two retaining blocks for fixing the threaded sleeve, two blocks A gap is formed between the blocks for the rotation of the retaining ring, and two stops are placed on both sides of the retaining ring.

By adopting the above technical solution, the retaining ring rotates between the two blocks, and the circumferential rotation of the rotating shaft and the telescopic rod does not receive the constraint; the blocking of the blocking block on both sides of the retaining ring, the rotating shaft and the threaded sleeve are positioned in the axial position The threaded sleeve is relatively stationary relative to the support seat, so the threaded sleeve drives the telescopic rod to move telescopically relative to the support base.

When the cylinder 55 is pushed out, the rectangular electronic device is placed on the receiving plate 51, and then the side plates 31 are moved toward each other to clamp the electronic device.

As shown in FIG. 2, four vertically disposed springs 54 are soldered and fixed on the bottom plate 56, and four circular through holes 53 are formed in the receiving plate 51, and the spring 54 can pass through the through holes 53; The upper end cover is provided with a flexible plate 52, and the flexible plate 52 is made of rubber.

As shown in FIG. 3, after the clamp 31 holds the electronic device, after the push cylinder 55 is retracted, the receiving plate 51 is placed below the upper end of the spring 54. The flexible board 52 is supported by the upper end of the spring 54 to achieve the suspended support of the flexible board 52. The advantage of this design is that if the electronic device is not effectively clamped due to the error of the inspector, the electrons are rotated during the rotation of the splint 31. The device is dropped on the flexible board 52, and it can be seen that the soft board 52 is soft and plays a buffering effect, so that the electronic device is not easy to be broken; and the spring 54 plays a secondary buffering effect for some of the higher quality electrons. The device, the spring 54 brings a more excellent cushioning effect.
