[0013] Preferably, a counterweight block is provided at one end of the first connecting rod close to the correction block.

[0014] A method for using a positioning device for improving the use effect of a digital screen comprises the following steps:

[0015] Step 1: Before using the digital screen, place the digital screen on the top of the placement plate and turn the handle to make the handle drive the rotating rod to rotate, the rotating rod drives the reset gear, the reset gear drives the reset gear plate to move upward, the reset gear plate drives the synchronization bar to move, the synchronization bar drives the first positioning block and the second positioning block to move, so that the first positioning block and the second positioning block reach the maximum height, and one corner of the digital screen fits the motor;

[0016] Step 2: After placing the digital tablet, continue to turn the handle to move the second slider to the bottom of the initial slot. At this time, the spring releases its elastic potential energy and drives the second slider to move to the inner wall of the initial slot. At this time, the reset gear stops meshing with the reset tooth plate, causing the reset tooth plate to move downward under the action of gravity. The reset tooth plate drives the synchronization bar to move, and the synchronization bar drives the first positioning block and the second positioning block to move. When the correction block abuts against the digital screen, the correction block moves relative to the limit slot, and the correction block drives the limit block to move to the top of the limit slot, thereby causing the limit block to hinder the movement of the limit slot, the limit slot hinders the movement of the second positioning block, the second positioning block hinders the movement of the synchronization bar, and the synchronization bar hinders the movement of the first positioning block, so that the top of the first positioning block is in contact with the digital screen. The top of the digital screen is flush with the top of the first positioning block, which prevents the top part of the first positioning block from being higher than the digital screen, causing obstruction and friction on the wrist when using the digital screen. At the same time, the correction block drives one end of the first connecting rod to move, and the first connecting rod rotates with the first rotating axis as the axis, so that the other end of the first connecting rod moves toward the second positioning block. The other end of the first connecting rod drives the second connecting rod to move, and the second connecting rod drives one end of the third connecting rod to move, so that the third connecting rod rotates with the second rotating axis as the axis, and the end of the third connecting rod away from the second connecting rod moves toward the second positioning block. The third connecting rod drives the auxiliary block to move, so that the auxiliary block moves to abut against the synchronization bar, so that the synchronization bar will not tilt toward the end close to the first positioning block, thereby improving the positioning effect of the device on the digital screen;

[0017] Step 3: After the position of the first positioning block is corrected, the motor is started to drive the screw device to operate, and the screw device drives the first positioning block to move toward the second positioning block, so that the first positioning block and the second positioning block squeeze the digital screen, so that the digital screen is positioned and will not be displaced during use, which will affect the use effect;

[0018] Step 4: After the digital screen is positioned, continue to rotate the handle, so that the handle drives the rotating rod to rotate, and the rotating rod drives the adjusting gear to rotate, and the adjusting gear is meshed with the adjusting tooth plate, so that the adjusting gear moves along the adjusting tooth plate away from the fixed plate, and the adjusting gear drives the placement plate to move, and according to the required inclination of the digital screen, the second slider is rotated to the bottom end of the inclination slot corresponding to the inclination angle, so that the spring releases the elastic potential energy, and pushes the second slider to move to the inner wall of the inclination slot, so as to complete the adjustment and fixation of the inclination angle of the digital screen, and further improve the use effect of the digital screen;

[0019] Step 5: After using the digital screen, start the motor to drive the screw device to operate, and the screw device drives the first positioning block to reset. Remove the digital screen and turn the handle to move the second slider away from the tilting slot. At this time, the handle stops engaging with the adjustment gear, thereby resetting the placement plate to facilitate the placement of the digital screen for next use.

[0020] The present invention is beneficial in that:

[0021] 1. The present invention provides a correction component. Before positioning a thinner digital screen, the second positioning block moves under the action of gravity. The second positioning block drives the correction block and the synchronization bar to move. The synchronization bar drives the first positioning block to move. When the correction block abuts against the digital screen, the correction block moves relative to the limiting slot. The correction block drives the limiting block to move to the top of the limiting slot, so that the limiting block blocks the movement of the limiting slot. The limiting slot blocks the movement of the second positioning block. The second positioning block blocks the movement of the synchronization bar. The synchronization bar blocks the movement of the first positioning block, so that the top of the first positioning block is flush with the top of the digital screen. This avoids the problem that when the digital screen is thin, the thickness of the positioning block is higher than the thickness of the digital screen. After the digital screen is positioned, the part of the positioning block that is higher than the digital screen is easy to cause obstruction and friction to the wrist or arm during use, affecting the use effect of the digital screen. This reduces the interference of the device on the hand during the use of the digital screen, improves the user experience, and improves the use effect of the digital screen.

[0022] 2. The present invention sets an adjustment component. When the digital screen needs to have a certain tilt angle, the handle is rotated to make the handle drive the rotating rod to rotate, and the rotating rod drives the adjusting gear to rotate. The adjusting gear is meshed with the adjusting tooth plate, so that the adjusting gear moves along the adjusting tooth plate in a direction away from the fixed plate, and the adjusting gear drives the placement plate to move, so that the digital screen forms a certain tilt, which can meet the user's need to tilt the digital screen, and avoids the problem that the device cannot meet the user's needs when the user needs the digital screen to tilt at a certain angle to improve work efficiency, which affects the user's experience and reduces the use effect of the digital screen. The user experience is improved and the use effect of the digital screen is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] A method for using a positioning device for improving the use effect of a digital screen comprises the following steps:

[0040] Step 1: Before using the digital screen, place the digital screen on the top of the placement plate 1, and turn the handle 16 to make the handle 16 drive the rotating rod 15 to rotate, the rotating rod 15 drives the reset gear 14, the reset gear 14 drives the reset gear plate 13 to move upward, the reset gear plate 13 drives the synchronization bar 9 to move, the synchronization bar 9 drives the first positioning block 2 and the second positioning block 3 to move, so that the first positioning block 2 and the second positioning block 3 reach the maximum height, and one corner of the digital screen is fitted with the motor 4;

[0041] Step 2: After placing the digital tablet, continue to rotate the handle 16 to move the second slider 23 to the bottom of the initial slot 24. At this time, the spring 22 releases its elastic potential energy and drives the second slider 23 to move to the inner wall of the initial slot 24. At this time, the reset gear 14 stops meshing with the reset tooth plate 13, so that the reset tooth plate 13 moves downward under the action of gravity, and the reset tooth plate 13 drives the synchronization bar 9 to move, and the synchronization bar 9 drives the first positioning block 2 and the second positioning block 3 to move. When the correction block 6 abuts against the digital screen, the correction block 6 moves relative to the limit slot 7, and the correction block 6 drives the limit block 8 to move to the top of the limit slot 7, thereby making the limit block 8 hinder the movement of the limit slot 7, and the limit slot 7 hinders the movement of the second positioning block 3, and the second positioning block 3 hinders the movement of the synchronization bar 9, and the synchronization bar 9 hinders the movement of the first positioning block 2. The top of the positioning block 2 is flush with the top of the digital screen to prevent the top part of the first positioning block 2 from being higher than the digital screen, causing obstruction and friction to the wrist when using the digital screen. At the same time, the correction block 6 drives one end of the first connecting rod 26 to move, and the first connecting rod 26 rotates with the first rotating shaft 27 as the axis, so that the other end of the first connecting rod 26 moves toward the second positioning block 3. The other end of the first connecting rod 26 drives the second connecting rod 28 to move, and the second connecting rod 28 drives one end of the third connecting rod 29 to move, so that the third connecting rod 29 rotates with the second rotating shaft 30 as the axis, and the end of the third connecting rod 29 away from the second connecting rod 28 moves toward the second positioning block 3. The third connecting rod 29 drives the auxiliary block 31 to move, so that the auxiliary block 31 moves to abut against the synchronization bar 9, so that the synchronization bar 9 will not tilt toward the end close to the first positioning block 2;

[0042] Step 3: After the position of the first positioning block 2 is corrected, the motor 4 is started to drive the screw device 5 to operate, and the screw device 5 drives the first positioning block 2 to move toward the second positioning block 3, so that the first positioning block 2 and the second positioning block 3 squeeze the digital screen, so that the digital screen is positioned and will not be displaced during use, which will affect the use effect;

[0043] Step 4: After the digital screen is positioned, continue to rotate the handle 16, so that the handle 16 drives the rotating rod 15 to rotate, and the rotating rod 15 drives the adjusting gear 17 to rotate, and the adjusting gear 17 is meshed with the adjusting tooth plate 18, so that the adjusting gear 17 moves along the adjusting tooth plate 18 away from the fixed plate 19, and the adjusting gear 17 drives the placement plate 1 to move, and according to the required inclination of the digital screen, the second slider 23 is rotated to the bottom end of the inclination slot 25 corresponding to the inclination angle, so that the spring 22 releases the elastic potential energy, and pushes the second slider 23 to move to the inner wall of the inclination slot 25, so as to complete the adjustment and fixation of the inclination angle of the digital screen, and further improve the use effect of the digital screen;

[0044] Step 5: After using the digital screen, start the motor 4 to drive the screw device 5 to operate, and the screw device 5 drives the first positioning block 2 to reset. Remove the digital screen, turn the handle 16 to make the second slider 23 away from the tilting slot 25.

[0045] Embodiment 2

[0046] See also Figure 3-4 , Figure 6 , Figure 8-9 As shown, compared with Example 1, as another embodiment of the present invention, the adjustment component includes an adjustment gear 17 arranged on the outer wall of the rotating rod 15, and a plurality of adjustment gears 17 are evenly arranged. An adjustment tooth plate 18 is meshed and installed on one side of the adjustment gear 17, and the adjustment tooth plate 18 is fixedly installed on the top of the fixed plate 19, and the fixed plate 19 is rotatably installed on the bottom end of the placement plate 1; by setting the adjustment component, when the digital screen needs to have a certain tilt angle, the rotating handle 16 is rotated to make the rotating handle 16 drive the rotating rod 15 to rotate, and the rotating rod 15 drives the adjustment gear 17 to rotate, and the adjustment gear 17 is meshed with the adjustment tooth plate 18, so that the adjustment gear 17 moves along the adjustment tooth plate 18 in a direction away from the fixed plate 19, and the adjustment gear 17 drives the placement plate 1 to move, so that the digital screen forms a certain tilt, which can meet the user's demand for tilting the digital screen, and avoids the problem that when the user needs the digital screen to be tilted at a certain angle in order to improve work efficiency, the device cannot meet the user's needs, affects the user's experience, and reduces the use effect of the digital screen, improves the user's experience, and improves the use effect of the digital screen.

[0047] See also Figure 4 and Figure 7As shown, the fixing component includes a gear adjuster 20 arranged on the outer wall of the rotating rod 15, and the inner wall of the gear adjuster 20 is provided with an initial position groove 24 and an inclined position groove 25, and a plurality of inclined position grooves 25 are provided.

The other end of the spring 22 is installed on the inner wall of the second slide groove 21, and the second slide groove 21 is provided on the outer wall of the rotating rod 15; by setting the fixing component, after the correction component is reset, the handle 16 can be rotated to move the second slider 23 to the bottom end of the initial position groove 24. At this time, the spring 22 releases its elastic potential energy and pushes the second slider 23 to move to the inner wall of the initial position groove 24. At this time, the reset tooth plate 13 stops meshing with the reset gear 14, so that the synchronization bar 9 can move under the action of gravity to correct the position of the first positioning block 2. When the joint component adjusts the inclination of the placement plate 1, the handle 16 can be rotated to move the second slider 23 to the bottom end of the inclined slot 25 corresponding to the required inclination angle. At this time, the spring 22 releases its elastic potential energy to push the second slider 23 to move to the inner wall of the inclined slot 25. When the second slider 23 moves to the initial slot 24 or the inner wall of the inclined slot 25, by setting the rotation direction side of the second slider 23 as an inclined part and the other side as a straight part, the rotating rod 15 can only rotate unidirectionally in the direction of the inclined part, avoiding the situation that when the adjustment component is in operation, the rotating rod 15 is rotated to the corresponding position, and the gravity of the placement plate 1 easily causes the rotating rod 15 to rotate, so that the adjusted inclination angle of the placement plate 1 changes, affecting the operation effect of the adjustment component, reducing the use effect of the digital screen, improving the stability of the adjustment component, and thereby improving the use effect of the digital screen.

[0048] See also Figure 1-4 , Figure 6 , Figure 8-9As shown, the auxiliary component includes a first connecting rod 26 arranged at the top of the correction block 6, a first rotating shaft 27 is installed in the middle of one side of the first connecting rod 26, the first rotating shaft 27 is fixedly installed at the top of the second positioning block 3, the end of the first connecting rod 26 away from the correction block 6 is rotatably installed with the second connecting rod 28, the bottom end of the second connecting rod 28 is rotatably installed with the third connecting rod 29, a second rotating shaft 30 is installed in the middle of one side of the third connecting rod 29, the second rotating shaft 30 is fixedly installed on one side of the reset tooth plate 13, and the end of the third connecting rod 29 away from the second connecting rod 28 is rotatably installed with the auxiliary block 31; by setting the auxiliary component, when the correction component is in operation, the correction block 6 moves in the direction away from the second positioning block 3, so that the correction block 6 drives one end of the first connecting rod 26 to move, and the first connecting rod 26 rotates with the first rotating shaft 27 as the axis, so that the other end of the first connecting rod 26 moves toward the second positioning block 3, and the other end of the first connecting rod 26 One end drives the second connecting rod 28 to move, and the second connecting rod 28 drives one end of the third connecting rod 29 to move, so that the third connecting rod 29 rotates with the second rotating shaft 30 as the axis, and the end of the third connecting rod 29 away from the second connecting rod 28 moves toward the second positioning block 3, and the third connecting rod 29 drives the auxiliary block 31 to move, so that the auxiliary block 31 moves to abut against the synchronization bar 9, so that the synchronization bar 9 will not tilt toward the end close to the first positioning block 2, thereby keeping the first positioning block 2 and the digital tablet in a horizontal position, avoiding that after the first positioning block 2 is corrected, the end of the synchronization bar 9 close to the first positioning block 2 is easily moved down slightly due to gravity, resulting in the first positioning block 2 being unable to keep level with the digital screen, thereby affecting the positioning effect of the device on the digital screen, making the position of the digital screen easy to change during use, reducing the use effect of the digital screen, improving the positioning effect of the device on the digital screen, and thereby improving the use effect of the digital screen.

[0049] See also Figure 1-4 , Figure 6 , Figure 8-9 As shown, the length between the first and last tooth blocks on the outer wall of the reset gear 14 is the same as the length between the top and bottom ends of the limiting groove 7; by setting the length between the first and last tooth blocks on the outer wall of the reset gear 14, when the limiting block 8 moves to the top end of the limiting groove 7, the reset tooth plate 13 stops meshing with the reset gear 14, so that the reset gear 14 will not cause motion interference to the rotating rod 15, thereby avoiding the reset gear 14 driving the reset tooth plate 13 to move away from the reset gear 14, so that after the second positioning block 3 is reset, the synchronization bar 9 abuts against the top end of the inner wall of the placement plate 1, causing the reset tooth plate 13 to continue to mesh with the reset gear 14, thereby hindering the rotation of the reset gear 14.

[0050] See also Figure 4 , Figure 6-9As shown, the angle between the first and last tooth blocks on the outer wall of the adjusting gear 17 is the same as the angle between the first and last tooth blocks on the outer wall of the tilting slot 25; by setting the angle between the first and last tooth blocks on the outer wall of the adjusting gear 17, when the second slider 23 moves from the inner wall of the initial slot 24 to the inner wall of the first tilting slot 25, the adjusting gear 17 is simultaneously engaged with the adjusting tooth plate 18, and the user can accurately adjust the tilt angle of the digital screen according to the tilting slot 25, thereby avoiding the angle between the first and last tooth blocks on the outer wall of the adjusting gear 17 being different from the angle between the first and last tooth blocks on the outer wall of the adjusting gear 17, resulting in errors in the tilt angle determined by the tilting slot 25 when the handle 16 is rotated to adjust the tilt angle of the placement plate 1, thereby affecting the user experience of the digital screen during use, reducing the impact on the use effect of the digital screen, making the adjustment component to the inclination of the digital screen more accurate, and improving the use effect of the digital screen.

[0051] See also Figure 1-4 , Figure 8-9 As shown, a counterweight block is provided at one end of the first connecting rod 26 close to the correction block 6; by providing the counterweight block, before the correction assembly is operated, the end of the first connecting rod 26 close to the counterweight block can be tilted under the action of gravity and abut against the top of the correction block 6, so that the auxiliary block 31 abuts against one end of the synchronization bar 9, avoiding the end of the first connecting rod 26 close to the correction block 6 from tilting up, thereby causing the end of the second rotating shaft 30 close to the auxiliary block 31 to tilt up, causing the auxiliary block 31 to stop abutting against the synchronization bar 9, which can easily cause the auxiliary block 31 to rotate around one end of the third connecting rod 29 as the axis, making the auxiliary block 31 perpendicular to the synchronization bar 9, thereby affecting the subsequent auxiliary support effect of the auxiliary block 31 on the synchronization bar 9.

[0052] Working principle: Before using the digital screen, place the digital screen on the top of the placement plate 1, and turn the handle 16, so that the handle 16 drives the rotating rod 15 to rotate, the rotating rod 15 drives the reset gear 14, the reset gear 14 drives the reset gear plate 13 to move upward, the reset gear plate 13 drives the synchronization bar 9 to move, the synchronization bar 9 drives the first positioning block 2 and the second positioning block 3 to move, so that the first positioning block 2 and the second positioning block 3 reach the maximum height, and one corner of the digital screen is fitted with the motor 4;

[0053] After placing the digitizer, continue to rotate the handle 16 to move the second slider 23 to the bottom end of the initial slot 24. At this time, the spring 22 releases its elastic potential energy, driving the second slider 23 to move to the inner wall of the initial slot 24. At the same time, the reset gear 14 stops meshing with the reset toothed plate 13, so that the reset toothed plate 13 moves downward under the action of gravity, and the reset toothed plate 13 drives the synchronization bar 9 to move, and the synchronization bar 9 drives the first positioning block 2 and the second positioning block 3 to move. When the correction block 6 abuts against the digitizer, the correction block 6 moves relative to the limit slot 7, and the correction block 6 drives the limit block 8 to move to the top end of the limit slot 7, thereby making the limit block 8 hinder the movement of the limit slot 7, the limit slot 7 hinders the movement of the second positioning block 3, the second positioning block 3 hinders the movement of the synchronization bar 9, and the synchronization bar 9 hinders the movement of the first positioning block 2, so that the top end of the first positioning block 2 and the digitizer are in contact. The top of the screen is flush, so as to prevent the top part of the first positioning block 2 from being higher than the digital screen, causing obstruction and friction to the wrist when using the digital screen. At the same time, the correction block 6 drives one end of the first connecting rod 26 to move, and the first connecting rod 26 rotates with the first rotating shaft 27 as the axis, so that the other end of the first connecting rod 26 moves toward the second positioning block 3. The other end of the first connecting rod 26 drives the second connecting rod 28 to move, and the second connecting rod 28 drives one end of the third connecting rod 29 to move, so that the third connecting rod 29 rotates with the second rotating shaft 30 as the axis, and the end of the third connecting rod 29 away from the second connecting rod 28 moves toward the second positioning block 3. The third connecting rod 29 drives the auxiliary block 31 to move, so that the auxiliary block 31 moves to abut against the synchronization bar 9, so that the synchronization bar 9 will not tilt toward the end close to the first positioning block 2, thereby improving the positioning effect of the device on the digital screen.

[0054] After the position of the first positioning block 2 is corrected, the motor 4 is started to drive the screw device 5 to operate, and the screw device 5 drives the first positioning block 2 to move toward the second positioning block 3, so that the first positioning block 2 and the second positioning block 3 squeeze the digital screen, so that the digital screen is positioned and will not be displaced during use, which will affect the use effect;

[0055] After the digital screen is positioned, the handle 16 is rotated continuously, so that the handle 16 drives the rotating rod 15 to rotate, and the rotating rod 15 drives the adjusting gear 17 to rotate, and the adjusting gear 17 is meshed with the adjusting tooth plate 18, so that the adjusting gear 17 moves along the adjusting tooth plate 18 in a direction away from the fixing plate 19, and the adjusting gear 17 drives the placement plate 1 to move, and according to the required inclination of the digital screen, the second slider 23 is rotated to the bottom end of the inclination slot 25 corresponding to the inclination angle, so that the spring 22 releases the elastic potential energy, and pushes the second slider 23 to move to the inner wall of the inclination slot 25, so as to complete the adjustment and fixation of the inclination angle of the digital screen, and further improve the use effect of the digital screen;

[0056] After using the digital screen, start the motor 4 to drive the screw device 5 to operate, and the screw device 5 drives the first positioning block 2 to reset. Remove the digital screen, turn the handle 16 to make the second slider 23 away from the tilting slot 25. At this time, the handle 16 stops engaging with the adjustment gear 17, thereby resetting the placement plate 1, which is convenient for the placement of the digital screen when it is used next time.
