DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, a teaching device for electronic product scene application based on a single-chip microcomputer includes a base 1, on which a single-chip microcomputer mounting plate 2 for mounting a single-chip microcomputer is provided, and on which a guide rod 6 is provided, which is arranged horizontally and arranged at the bottom of one side of the single-chip microcomputer mounting plate 2. Two fixing seats 8 are correspondingly arranged on the base 1, and the guide rod 6 is arranged between the two fixing seats 8. A plurality of sliding cable fixers 7 are connected to the guide rod 6, and the sliding cable fixer 7 includes a fixer body 71, on which a guide hole 72 is provided, and the guide rod 6 passes through the guide hole 72; the fixer body 71 is provided with a locking mechanism and a cable clamp block 74, and the cable clamp block 74 is provided with a cable clamp groove 75.

[0022] The sliding cable holder 7 can be slidably adjusted on the guide rod 6, and the locking mechanism is used to achieve locking or loosening between the sliding cable holder 7 and the guide rod 6. During the practical training, the students can clamp and fix the cables by the cable clamp block 74 on the holder body 71, and can adjust the position of the cables by sliding the sliding cable holder 7, so that the cables can be moved to the desired position, thereby arranging the cables and avoiding the influence of the students' practical training operations on the operating table due to the large number of cables and disorder. When it is necessary to slide the sliding cable holder 7, the guide rod 6 and the holder body 71 are first loosened by the locking mechanism, and then the sliding cable holder 7 can be slidably adjusted along the guide rod 6; when the sliding cable holder 7 moves to the target position, the guide rod 6 and the holder body 71 are locked by the locking mechanism, so that the sliding cable holder 7 is fixed at the current position.

[0023] The cable clamp block 74 is made of a flexible material. In this embodiment, the cable clamp block 74 is made of rubber.

[0024] The fixing body 71 is provided with an installation cavity 78, and the locking mechanism includes a pressing column 77 and a rotating shaft 76 rotatably connected in the installation cavity 78. A rotating rod 710 is provided on the rotating shaft 76, and the rotating shaft 76 is located in the middle position of the rotating rod 710. An elastic member 711 is provided between one end of the rotating rod 710 and the inner wall of the installation cavity 78. A sliding groove is provided on the fixing body 71, and the sliding groove is arranged along the radial direction of the guide hole. The sliding groove is located on one side of the guide hole 72. A top block 714 is slidably connected in the sliding groove. One end of the top block 714 contacts one end of the rotating rod 710 away from the elastic member 711, and the other end of the top block 714 contacts the outer surface of the guide rod 6; a through hole 712 is provided on the fixing body 71, and one end of the pressing column 77 contacts one end of the rotating rod 710 close to the elastic member 711, and the other end of the pressing column 77 passes through the through hole 712. The pressing column 77 is divided into two sections with different diameters, one of which has a diameter smaller than the diameter of the through hole 712 and passes through the through hole 712 ; the other has a diameter larger than the diameter of the through hole 712 and is located in the installation cavity 78 .

[0025] When the pressing column 77 is not pressed, the rotating rod 710, under the elastic action of the elastic member 711, has one end pressed against one end of the top block 714, and the other end of the top block 714 presses against the guide rod 6, so that the sliding cable holder 7 is in a locked state; when the pressing column 77 is pressed, the rotating rod 710 overcomes the elastic force of the elastic member 711 and rotates, so that one end of the rotating rod 710 releases the top block 714, and then the top block 714 releases the guide rod 6, so that the sliding cable holder 7 can slide freely on the guide rod 6, so as to adjust the position of the sliding cable holder 7.

[0026] In this embodiment, the elastic member 711 is a spring sheet, and the cross section of the spring sheet is "C" shaped. The material of the spring sheet is spring steel. One end of the spring sheet is fixedly connected to the rotating rod 710, and the other end of the spring sheet is fixedly connected to the inner wall of the installation cavity 78.

[0027] The base 1 is provided with a socket 5, a power interface 4 and a power switch 3. The power interface 4 is used to connect a power line.

[0028] Furthermore, a slot 73 for placing a recording card is provided on one side of the holder body 71. During the training operation, the recording card can be inserted into the slot 73, and the recording card can record the information of the cable clamped by the holder body 71, such as how the cable is connected, which interface the cable is connected to, etc., so that the learner can quickly identify and find the corresponding cable, which is convenient for the student's operation.

[0029] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
