[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-5 As shown, the utility model provides a printer display fixing bracket for fixing a display screen 7, comprising a mounting plate 1, a magnifying glass 5 for magnifying an image is provided on the front side of the mounting plate 1, and an extension arm 3 is provided between the magnifying glass 5 and the mounting plate 1;

[0025] The extension arm 3 includes a U-shaped tube 301 hinged to the front side of the mounting plate 1 through a damping hinge, and the rear side of the magnifying glass 5 is hinged to two insertion rods 302 through a damping hinge. The rear ends of the two insertion rods 302 extend to the inside of the U-shaped tube 301 through the two open ends of the U-shaped tube 301 respectively. The distance between the magnifying glass 5 and the display screen 7 can be adjusted by telescoping the insertion rods 302 on the U-shaped tube 301, and the damping hinge can adjust the angle of the magnifying glass 5.

[0026] The display screen 7 is mounted and fixed on the mounting plate 1, and a magnifying glass 5 is arranged on the front side of the mounting plate 1. The magnifying glass 5 can magnify the content displayed on the display screen 7, so as to facilitate observation. In this way, there is no need to set the size of the display screen 7 too large. Selecting a smaller display screen 7 can greatly save the production cost of the printer. The magnifying glass 5 is connected to the mounting plate 1 through the extension arm 3 and the damping hinge. When in use, the magnifying glass 5 is moved to the front of the mounting plate 1 by rotating the extension arm 3. When not in use, the extension arm 3 can be rotated to fold the mounting plate 1 under the mounting plate 1 without taking up space. At the same time, the insertion rod 302 can be extended and retracted on the U-shaped tube 301 to adjust and control the distance between the magnifying glass 5 and the display screen 7, thereby adjusting the magnification of the image.

[0027] After controlling the length change of the extension arm 3, the length of the extension arm 3 needs to be fixed, such as Figure 4 ,5 As shown, a rubber head 308 is fixedly provided at the rear end of the insertion rod 302, and the outer end of the rubber head 308 contacts the inner wall of the U-shaped tube 301 to play a sealing role.

[0028] The outer end of the U-shaped tube 301 is sleeved with a closed ring 303, the outer end of the closed ring 303 is provided with an outer hole 305, and the outer end of the U-shaped tube 301 is provided with an inner hole 304. The closed ring 303 can rotate to make the inner hole 304 coincide with the outer hole 305. After the two coincide, the U-shaped tube 301 can be connected to the outside world.

[0029] A torsion spring 307 is fixedly provided at the front end of the closed ring 303 , and a fixing ring 306 fixed to the outer end of the U-shaped tube 301 is fixedly provided at the front end of the torsion spring 307 . A paddle is fixedly provided at the outer end of the closed ring 303 , and the rotation of the closed ring 303 is conveniently controlled by the paddle.

[0030] Under normal conditions, the inner hole 304 and the outer hole 305 are staggered, and the inside of the U-shaped tube 301 is in a closed state through the rubber head 308, and the movement of the insertion rod 302 will change the air pressure inside the U-shaped tube 301, so that the insertion rod 302 will be difficult to move due to the resistance generated by the air pressure. In this way, the position of the insertion rod 302 is fixed under normal conditions, and the overall length of the extension arm 3 is fixed. When the length of the extension arm 3 needs to be adjusted, the closing ring 303 is rotated by the paddle so that the inner hole 304 and the outer hole 305 coincide with each other. At this time, the U-shaped tube 301 is no longer closed, and moving the insertion rod 302 will allow air to smoothly enter and exit the U-shaped tube 301, and the resistance of air pressure disappears, so that the length of the extension arm 3 can be smoothly adjusted. After adjustment, the paddle is released, and the elastic force of the torsion spring 307 drives the closing ring 303 to rotate, and the U-shaped tube 301 is closed again, thereby fixing the length of the extension arm 3.

[0031] In order to avoid damage to the display screen 7, Figure 1 , 2 As shown, an inlay groove 6 is provided on the front side of the mounting plate 1 , and the display screen 7 is inlaid in the inlay groove 6 and can move synchronously with the mounting plate 1 .

[0032] A tempered film 4 is provided on the front side of the display screen 7, and a frame 8 is fixed on the outer end of the tempered film 4. The frame 8 is detachably provided on the front side of the mounting plate 1 by bolts. The tempered film 4 is closely attached to the front side of the display screen 7 to protect the display screen 7 without affecting the touch operation.

[0033] The display screen 7 is fixed by embedding the embedding groove 6 on the mounting plate 1, and the tempered film 4 is installed on the front side of the mounting plate 1 through the frame 8. The tempered film 4 is tightly attached to the front side of the display screen 7, does not affect the touch function of the display screen 7, and can protect the display screen 7.

[0034] In order to flexibly adjust the angle of the display screen 7, Figure 1 , 3 As shown, a back plate 2 is provided on the rear side of the mounting plate 1, and the mounting plate 1 and the back plate 2 are movably connected via a ball hinge 9. A spring 10 is provided on the outer side of the ball hinge 9, and both ends of the spring 10 are respectively fixedly connected to the rear side of the mounting plate 1 and the front side of the back plate 2. After adjusting the angle of the mounting plate 1, the elastic force of the spring 10 can drive the mounting plate 1 back to its original position.

[0035] The back plate 2 is detachably mounted on the outer end of the printer, so that the fixed bracket is connected to the printer. The back plate 2 is connected to the front mounting plate 1 through a ball hinge 9 and a spring 10. The mounting plate 1 can rotate in all directions under the action of the ball hinge 9 to adjust the direction of the display screen 7. During this process, the spring 10 will bend as the display screen 7 rotates, and eventually the elastic force of the spring 10 will drive the mounting plate 1 back to its original position.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
