Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1-5 As shown, the utility model provides a computer science and technology display device, including a display device body 1, which is suitable for displaying computer science and technology. The display device body 1 includes a mobile cart 2, a display cabinet 3 is fixedly installed on the top of the mobile cart 2, and push rods 4 are fixedly installed on the edge positions of both sides of the top of the mobile cart 2. Adjustment units are arranged on both sides of the display cabinet 3, and a positioning unit is arranged inside the display cabinet 3. The positioning unit includes a placement plate 31 that is detachably engaged with the inside of the display cabinet 3. Positioning plates 316 are slidably installed in grooves on both sides of the top of the placement plate 31, and a positioning hole 317 is opened on the bottom end of the placement plate 31. The positioning plate 316 is A toothed cross plate 3161 is fixedly installed on one side of the bottom end, and a piston rod is movably inserted inside the other end of the toothed cross plate 3161, and the other end of the piston rod is fixedly installed on the inner wall of the top groove of the placement plate 31, and a rotating gear 3162 is meshingly connected on the inner side of the toothed cross plate 3161. A driving rod 3163 is fixedly installed on the bottom end of the rotating gear 3162, and the other end of the driving rod 3163 passes through the groove and extends onto the outer surface of the bottom end of the placement plate 31, and a handle 3164 is fixedly installed on the other end of the driving rod 3163, and a positioning rod 3165 is movably inserted inside the handle 3164, and the other end of the positioning rod 3165 is threadedly connected to the inside of the positioning hole 317.

[0027] Furthermore, by placing the computer science teaching aids on the top of the placement plate 31, the handle 3164 at the bottom of the placement plate 31 is rotated, and the handle 3164 drives the driving rod 3163 to cause the rotating gear 3162 to rotate, thereby making the toothed cross plates 3161 on both sides move relative to each other, and the toothed cross plates 3161 drive the positioning plates 316 on both sides to move relative to each other until they are clamped on the outer shells on both sides of the teaching aids for clamping and positioning, so that the clamping distance of the positioning plates 316 on both sides can be adjusted according to the size of the teaching aids. After clamping, the positioning rod 3165 is rotated so that the other end of the positioning rod is threadedly connected to the inside of the positioning hole 317, so that the handle 3164 is fixed in position, thereby making the positioning plates 316 fixed in position.

[0028] Example 2

[0029] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the adjustment unit includes a support vertical plate 1 32 fixedly installed on the front ends of both sides of the display cabinet 3, a support vertical plate 2 33 is fixedly installed on the rear end of the support vertical plate 1 32, and a clamping hole 34 is provided inside the support vertical plate 2 33 and the support vertical plate 1 32, and a resisting vertical plate 35 is fixedly installed on both sides of the rear end of the display cabinet 3 behind the support vertical plate 2 33, and a limiting slide groove 36 is provided inside the resisting vertical plate 35, and a clamping block 311 is fixedly installed on both sides of the placement plate 31, and the clamping block 311 is detachably inserted in the inside of the clamping hole 34, and a telescopic rod 312 is fixedly installed on both sides of the rear end of the placement plate 31, and a return spring 313 is movably sleeved on the outer surface of the telescopic rod 312, and a resisting plate 314 is fixedly installed on the other end of the telescopic rod 312, and a limiting slider 315 is fixedly installed on both sides of the rear end of the resisting plate 314, and the limiting slider 315 is slidably installed in the inside of the limiting slide groove 36.

[0030] Furthermore, by pushing the placement plate 31 backward, the clamping blocks 311 on both sides are disengaged from the clamping holes 34. At this time, the telescopic rod 312 contracts and squeezes the reset spring 313, pulling the placement plate 31 up and down to the required position, so that the clamping blocks 311 are correspondingly inserted into the inside of the clamping holes 34. Under the elastic pushing force of the reset spring 313, the placement plate 31 is pushed forward so that it is subjected to the squeezing force and will not automatically disengage from the clamping holes 34, thereby the clamping position of the placement plate 31 can be adjusted as needed.

[0031] The following is a detailed description of the working principle of the computer science and technology demonstration device.

[0032] like Figure 1-5As shown, when in use, the mobile cart 2 is pushed by the push rod 4 so that the display cabinet 3 can be easily moved to any teaching point. When the computer science teaching aids are placed on the top of the placement plate 31, the handle 3164 at the bottom of the placement plate 31 is rotated, and the handle 3164 drives the driving rod 3163 to cause the rotating gear 3162 to rotate, thereby making the toothed horizontal plates 3161 on both sides move relative to each other, and the toothed horizontal plates 3161 drive the positioning plates 316 on both sides to move relative to each other until they are clamped on the two side shells of the teaching aids for clamping and positioning, so that the clamping distance of the positioning plates 316 on both sides can be adjusted according to the size of the teaching aids. After clamping, the positioning rod 3165 is rotated to make the other end of the positioning rod 3165 threadedly connected to the positioning hole 317. The handle 3164 is fixed in position, thereby the positioning plate 316 is fixed in position. The placement plate 31 can also adjust its position inside the display cabinet 3 according to the height of the teaching aids. The placement plate 31 can be pushed backward as needed to make the clamping blocks 311 on both sides disengage from the clamping holes 34. At this time, the telescopic rod 312 contracts and squeezes the reset spring 313, pulling the placement plate 31 up and down to the required position, so that the clamping blocks 311 are correspondingly inserted into the inside of the clamping holes 34, and the placement plate 31 is pushed forward under the elastic pushing force of the reset spring 313, so that it is subjected to the squeezing force and will not automatically disengage from the clamping holes 34, thereby the clamping position of the placement plate 31 can be adjusted as needed.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
