[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a fixture for attaching a touch screen includes two support plates 1, which are respectively fixed to the top surface of a base 2. Movable holes 3 are respectively opened on one side of each support plate 1. Electric push rods 4 are respectively fixed to the outer sides of each support plate 1. One end of each electric push rod 4 extends through the two movable holes 3 and is respectively fixed with a first clamping plate 5. A movable groove 6 is opened on the top surface of the base 2. Two second clamping plates 7 are movably arranged inside the movable groove 6. A bidirectional lead screw 8 is rotatably arranged inside the movable groove 6. A fixture is opened on the right side of the base 2. The base 2 has a rotating hole 9. A drive motor 10 is fixed on the right side of the base 2. The output shaft of the drive motor 10 passes through the rotating hole 9 and is fixedly connected to the right end of the bidirectional lead screw 8. Threaded holes 11 are opened on one side of each of the two second clamping plates 7. The two threaded holes 11 are threadedly connected to the threaded ends of the bidirectional lead screw 8. Mounting grooves 12 are opened on the top surfaces of the two second clamping plates 7 and the two first clamping plates 5. Third clamping plates 13 are movably installed inside the two mounting grooves 12. Springs 14 are fixed between the two third clamping plates 13 and the two mounting grooves 12.

[0023] In use, the operator first places the electronic device (not shown in the figure) on the top surface of the base 2, then places the touch screen (not shown in the figure) between several third clamping plates 13. Subsequently, the electric push rod 4 is activated to bring the two first clamping plates 5 closer together, which in turn brings the front and rear third clamping plates 13 closer together, allowing simultaneous clamping of the front and rear sides of the electronic device and the touch screen. At the same time, the drive motor 10 is activated to rotate the bidirectional lead screw 8, which brings the two second clamping plates 7 closer together, which in turn brings the left and rear third clamping plates 13 closer together, allowing simultaneous clamping of the left and right sides of the electronic device and the touch screen. Through this series of operations, the touch screen is precisely positioned directly above the electronic device. Afterward, the operator simultaneously presses several pressing plates 25. The pressing plates 25 transmit force to the third clamping plates 13 through the pressing column 24, causing the third clamping plates 13 to descend. At this time, the spring 14 is in a compressed state. When the third clamping plate 13 moves to the bottom, the touch screen and the electronic device are tightly attached, completing the attachment operation. By using the support plate 1, base 2, electric push rod 4, first clamping plate 5, second clamping plate 7, bidirectional lead screw 8, drive motor 10, third clamping plate 13 and spring 14 together, the electronic device and the touch screen can be clamped and fixed at the same time, and the two can be kept in a precise relative position. During the entire operation, the staff does not need to frequently manually align the electronic device and the touch screen, which reduces the difficulty and time of operation and improves the attachment efficiency and accuracy.

[0024] like Figures 1-3As shown, the inner wall of the movable groove 6 is provided with a first sliding groove 15 on the front and rear sides respectively, and the two second clamping plates 7 are respectively fixed with a first slider 16 on the front and rear sides respectively. The two first sliders 16 are slidably arranged in the two first sliding grooves 15 respectively.

[0025] In use, the cooperation between the first slide groove 15 and the first slider 16 helps to limit the second clamping plate 7, ensuring that the second clamping plate 7 will not shake or deviate when moving, thereby improving the stability of clamping.

[0026] like Figures 1-4 As shown, the inner sides of the two first clamping plates 5 and the two second clamping plates 7 are respectively fixed with first rubber pads 17, and the inner sides of the two third clamping plates 13 are respectively fixed with second rubber pads 18. The front and rear sides of the base 2 are respectively provided with suction grooves 19, and the top surface of the base 2 is provided with a number of suction holes 20. The number of suction holes 20 are respectively connected to the interior of the two suction grooves 19, and the interior of the two suction grooves 19 is respectively fixed with suction pipes 21.

[0027] During use, the combined use of the first rubber pad 17 and the second rubber pad 18 helps to buffer the clamping force when clamping and fixing the electronic device and the touch screen, avoiding damage to the surface of the electronic device and the touch screen from hard contact. At the same time, it increases friction and ensures the stability of clamping. The operator connects the suction pipe 21 to the suction pump (not shown in the figure). After starting the suction pump, the suction pump draws air from the bottom of the electronic device through the suction pipe 21 and the suction hole 20, so that the electronic device is in a negative pressure adsorption state on the base 2, which further improves the stability of the electronic device.

[0028] like Figures 2-4 As shown, the inner walls of the two mounting slots 12 are respectively provided with second sliding grooves 22, and the outer walls of the two third clamping plates 13 are respectively fixed with second sliders 23. The two second sliders 23 are slidably arranged in the two second sliding grooves 22. The top surfaces of several third clamping plates 13 are respectively fixed with pressing columns 24, and the top ends of several pressing columns 24 are respectively fixed with pressing plates 25.

[0029] During use, the cooperation between the second slide groove 22 and the second slider 23 helps to limit the movement of the third clamping plate 13, ensuring that the third clamping plate 13 will not wobble or shift when pressed, thus improving the stability of the third clamping plate 13 during pressing. The cooperation between the pressing column 24 and the pressing plate 25 allows the operator to press the third clamping plate 13 more easily and conveniently, improving the ease of use.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
