DETAILED DESCRIPTION

[0025] 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 without creative work are within the scope of protection of the utility model.

[0027] The side fixing assembly includes a first rotating rod 7 and a side fixing plate 18. Two sets of side fixing plates 18 are provided. The two sets of side fixing plates 18 are threadedly sleeved on the outer arc surface of the first rotating rod 7, and the transformer body 17 is located between the two sets of side fixing plates 18.

[0028] The other two sides of the transformer body 17 are provided with fixing components for fixing the other two sides of the transformer body 17;

[0029] The fixing assembly includes a fixing plate 11, a compression spring 12 and a moving module. The fixing plate 11 and the compression spring 12 are both provided with two groups. The two groups of fixing plates 11 are movably arranged inside the fixing box 1. The transformer body 17 is located between the two groups of fixing plates 11. The two groups of compression springs 12 are respectively installed on the corresponding surfaces of the corresponding fixing plates 11 and the fixing box 1. By placing the transformer body 17 on the corresponding surfaces of the two groups of fixing plates 11, the two groups of fixing plates 11 drive the transformer body 17 to move to the fixing box under the action of the compression springs 12. 1, and then the two groups of spring buckles 4 are driven by the moving module to be respectively engaged with the two groups of buckle rings 10, so that the transformer body 17 is fixed by the two groups of fixing plates 11, and then the first servo motor 2 is started to drive the two groups of side fixing plates 18 to approach the transformer body 17, so that the transformer body 17 is fixed again by the two groups of side fixing plates 18, so that the transformer body 17 of different sizes is fixed inside the fixing box 1, and the movement of the transformer body 17 is avoided, thereby improving the applicability of the overall fixing device.

[0030] Preferably, the side fixing component also includes a first servo motor 2 and a limit block 20, the first servo motor 2 is bolted to one side of the fixed box 1, one end of the first rotating rod 7 is keyed to the output end of the first servo motor 2, the other end of the first rotating rod 7 is rotatably connected to the inner wall of the fixed box 1, and the outer arc surface of the first rotating rod 7 is symmetrically provided with thread grooves in opposite directions at the midpoint, and the two groups of side fixing plates 18 are symmetrically sleeved on the outer arc surfaces of the two groups of thread grooves, respectively. By providing thread grooves in opposite directions on the outer arc surface of the first rotating rod 7, when the first servo motor 2 is started to drive the first rotating rod 7 to rotate, the two groups of side fixing plates 18 are synchronously moved toward or away from each other along the outer arc surface of the first rotating rod 7, thereby solving the problem of left and right displacement of the mutual inductor body 17.

[0031] It is worth noting that two groups of limit blocks 20 are provided, and both groups of limit blocks 20 are fixedly installed on the lower surface of the corresponding side fixing plate 18, and the bottom end of the fixed box 1 is provided with movable grooves 16 corresponding to the two groups of limit blocks 20. By setting the limit blocks 20 as convex blocks and inserting the limit blocks 20 into the movable grooves 16, the side fixing plate 18 can be moved while solving the problem of rotation or vertical displacement of the side fixing plate 18.

[0032] Furthermore, the mobile module includes a second servo motor 5, a mounting frame 6, a first moving block 8, a second moving block 9 and a second rotating rod 19. The mounting frame 6 is fixedly installed on the side of the fixed box 1, the second servo motor 5 is bolted to one end of the mounting frame 6, the second rotating rod 19 is rotatably set inside the mounting frame 6, and one end of the mounting frame 6 is keyed to the output end of the second servo motor 5. Starting the second servo motor 5 drives the second rotating rod 19 to rotate, and by installing the mounting frame 6 on the side of the fixed box 1, the stability of the working process of the mobile module is improved.

[0033] Furthermore, the outer arc surface of the second rotating rod 19 is symmetrically provided with threads in opposite directions at the midpoint, and the first moving block 8 and the second moving block 9 are symmetrically sleeved on the two sets of threaded outer arc surfaces respectively. By providing threads in opposite directions on the outer arc surface of the second rotating rod 19, the rotation of the second rotating rod 19 drives the first moving block 8 and the second moving block 9 to move toward or away from each other synchronously.

[0034] Specifically, both ends of the two groups of fixed plates 11 are fixedly connected with a snap-in block 13, and the inner wall of the fixed box 1 is provided with a snap-in groove 15 corresponding to the snap-in block 13. The snap-in block 13 is configured as a convex block. The snap-in block 13 is snapped into the inside of the snap-in groove 15, so that the fixed plate 11 can be moved while solving the problem of rotation and vertical displacement of the fixed plate 11.

[0035] It is worth mentioning that the two groups of fixing plates 11 are fixedly connected to the side of the clamping block 13 near one end of the mounting frame 6, and the two groups of connecting rods 3 are fixedly installed with a snap ring 10 at one end away from the fixing plate 11. The movement of the fixing plate 11 drives the connecting rod 3 to move synchronously, and drives the snap ring 10 to move, thereby facilitating the fixation of the position of the fixing plate 11.

[0036] In addition, spring buckles 4 corresponding to the snap rings 10 are fixedly installed on the lower surfaces of the first moving block 8 and the second moving block 9, and the snapping sides of the two groups of spring buckles 4 are arranged on the corresponding surfaces of the two groups of spring buckles 4. The two groups of spring buckles 4 are driven to approach the two groups of snap rings 10 synchronously by the movement of the first moving block 8 and the second moving block 9, and when the snapping sides of the spring buckles 4 contact the snap rings 10, the spring buckles 4 will snap the snap rings 10 into themselves, thereby fixing the position of the fixed plate 11, thereby solving the problem of movement of the transformer body 17.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
