[0024] By adopting the above technical solution, the top driving motor 56 of the top seat 52 is started to drive the screw 55 to rotate. Under the meshing connection between the screw 55 and the tooth block 54, the tooth block 54 is limited to move downward and tightly meshes with the tooth groove 53 to position and reinforce the slide plate 6, thereby making the structural stability of the slider 1 higher.

[0025] Specifically, the inner groove of the top seat 52 is in a square block structure, and the surface of the tooth block 54 is tightly fitted with the inner groove wall of the top seat 52 .

[0026] By adopting the above technical solution, the surface of the tooth block 54 and the inner groove wall of the top seat 52 are tightly fitted together, so that the meshing of the tooth block 54 and the tooth groove 53 can be more stable and firm.

[0027] Specifically, the auxiliary component 51 includes a positioning groove 511, a fixing plate 512 and a positioning block 513. The fixing plate 512 is installed on the side of the base 4. The fixing plate 512 has a positioning groove 511 inside. The surface of the screw rod 3 is covered with a positioning block 513, and the positioning block 513 is a circular ring structure.

[0028] By adopting the above technical solution, the positioning groove 511 inside the fixing plate 512 limits the positioning block 513 so that the screw rod 3 can be stably limited in rotation, which can achieve a better transmission control effect between the screw rod 3 and the slider 1.

[0029] When this embodiment is used, the stepper motor 10 drives the screw rod 3 to rotate.

[0033] By adopting the above technical solution, the limit sleeve 72 limits the limit block 71, and the rotating block 74 is engaged between the control rod 73 and the transmission block 75. Since the thread directions of the two end surfaces of the control rod 73 are opposite, the screw 8 and the through hole 76 are slidingly limited. The two transmission blocks 75 can respectively drive the screws 8 to move toward each other. Synchronous control of the movement of the two screws 8 can make the operation simpler and the adjustment accuracy higher.

[0034] When this embodiment is in use, the limiting sleeve 72 limits the limiting block 71, and the rotating block 74 is engaged with the control rod 73 and the transmission block 75. Since the thread directions of the two end surfaces of the control rod 73 are opposite, the screw 8 and the through hole 76 are limited by sliding. The two transmission blocks 75 can respectively drive the screws 8 to move toward each other. Synchronous control of the movement of the two screws 8 can make the operation simpler and the adjustment accuracy higher.

[0035] The driving motor 56 in the present invention is an existing disclosed technology, and the selected model is Z2D15W.

[0036] The structure and use principle of the slider 1, sleeve 2, screw 3, base 4, slide plate 6, screw 8, nut 9 and stepper motor 10 in the utility model have been disclosed in Chinese patent application No. 202220851191.2, which discloses a high-precision electric displacement transmission device. Its working principle is that the stepper motor 10 drives the screw 3 to rotate, and under the meshing connection between the screw 3 and the sleeve 2, the slide plate 6 and the base 4 slide and limit, and the sleeve 2 can drive the slider 1 to move in a limited manner. By controlling the two screws 8 to drive the steel ball at the end to connect with the ball groove on the surface of the sleeve 2, a certain buffer space can be left when the sleeve 2 jumps slightly, and the rotating nut 9 can fix the position of the screw 8.

[0037] The working principle and use process of the utility model are as follows: when the utility model is used, the stepper motor 10 drives the screw rod 3 to rotate. Under the meshing connection between the screw rod 3 and the shaft sleeve 2, the sliding limit shaft sleeve 2 between the slide plate 6 and the base 4 can drive the slider 1 to move in a limited manner. The positioning groove 511 inside the fixed plate 512 limits the positioning block 513, so that the screw rod 3 can be stably limited in rotation, and the transmission control effect between the screw rod 3 and the slider 1 can be better. The top drive motor 56 of the top seat 52 is started to drive the screw rod 55 to rotate. Under the meshing connection between the screw rod 55 and the tooth block 54, the tooth block 54 is limited to move downward and is tightly meshed with the tooth groove 53 to The plate 6 is positioned and reinforced, thereby making the structural stability of the slider 1 higher. The limit sleeve 72 limits the limit block 71. The rotating rotary block 74 is engaged and connected between the control rod 73 and the transmission block 75. Since the thread directions of the surfaces at both ends of the control rod 73 are opposite, the screw 8 and the through hole 76 are slidingly limited. The two transmission blocks 75 can respectively drive the screws 8 to move toward each other. Synchronous control of the movement of the two screws 8 can make the operation simpler and the adjustment accuracy higher. The screw 8 drives the steel ball at the end to connect with the ball groove on the surface of the sleeve 2. Then the nut 9 can be rotated to fix the position of the screw 8. A certain buffer space can be left when the sleeve 2 jumps slightly.
