One end of the driving rotating shaft 21, which is far away from the driving gear 22, extends from one end of the mounting block 1, which is far away from the driven rotating shaft 23, and at the moment, the driving rotating shaft 21 can be rotated to drive the driven rotating shaft 23 to rotate when reading the dial indicator, so that the rotation of the screw rod is realized, the degree of the dial indicator and the rotation of the driving screw rod can be realized by only one worker, and the labor force required for detecting the parallelism of the axis of the main shaft and the guide rail is reduced, so that the parallelism detection of the main shaft is more convenient.
As shown in fig. 3, when the driven rotating shaft 23 is used to drive the screw to rotate, the screw and the driven rotating shaft 23 need to be rotated synchronously, and after the parallelism detection of the spindle is completed, the driven rotating shaft 23 and the screw need to be separated. Therefore, one end of the driven rotating shaft 23 far away from the driven gear 24 is coaxially connected with a connecting sleeve 25, the end surface of the connecting sleeve 25 coaxially penetrates through a connecting groove 251, and the driven rotating shaft 23 can be inserted into the connecting groove 251.

One end of the screw rod dismantling handle can be inserted into the connecting groove 251, and one end, far away from the screw cap, of the screw rod of the connecting bolt 27 is abutted with the side wall of the screw rod. The connecting bolt 27 is used for fixing the position of the screw rod connectable sleeve 25, so that the screw rod can synchronously rotate along with the rotation of the driven rotating shaft 23, and meanwhile, the connecting sleeve 25 and the screw rod are more quickly assembled and disassembled, so that the use process of the screw rod rocking handle is more convenient.
As shown in fig. 2, when the driving shaft 21 is rotated to drive the driven shaft 23 to rotate, the relative positions of the driving shaft 21 and the driven shaft 23 need to be fixed, otherwise, the driving gear 22 cannot be meshed with the driven gear 24. Therefore, the driving rotating shaft 21 and the driven rotating shaft 23 are both connected with a limiting mechanism 3 for limiting the positions of the driving rotating shaft 21 and the driven rotating shaft, and the limiting mechanism 3 comprises a cylindrical limiting block 31 which is connected with the mounting block 1 and is arranged in a hollow mode, and two ends of the cylindrical limiting block 31 are opened, and two bearings 32 connected with the limiting block 31. The outer wall of the limiting block 31 is coaxially provided with a clamping groove 311, and one end of the limiting block 31 is penetrated by the clamping groove 311. The limiting block 31 can be inserted into the mounting block 1, the side wall, close to the axis of the limiting block 31, of the clamping groove 311 can be abutted against the inner wall of the mounting block 1, and the end face, which is not provided with the clamping groove 311, is fixed with the end face of the mounting block 1 by using bolts. The two bearings 32 are arranged in the inner cavity of the limiting block 31, the outer wall of the outer ring of the bearing is abutted with the inner wall of the limiting block 31, and the inner wall of the inner ring of the bearing is abutted with the side wall of the driving rotating shaft 21 or the driven rotating shaft 23. The position of the driving rotating shaft 21 and the driven rotating shaft 23 is limited by the limiting mechanism 3, so that the driving gear 22 can be meshed with the driven gear 24, and the steering mechanism 2 can be used stably.
As shown in fig. 2, when the steering mechanism 2 is used to drive the screw rod to rotate, the mounting block 1 needs to be fixed with the machine tool, so that the side wall of the limiting block 31 connected with the driven rotating shaft 23 is integrally formed with a connecting ring 33, two fastening bolts 34 penetrate through the end face of the connecting ring 33, which is close to the connecting groove 251, and the two fastening bolts 34 penetrate through the connecting ring 33 to be in threaded connection with the support frame for supporting the screw rod. When the parallelism between the axis of the main shaft and the guide rail is detected, the mounting block 1 is detached from and connected with the machine tool through the fastening bolt 34, so that the screw rod rocking handle is more convenient to use.
As shown in fig. 2, since the heights of different workers are different, in order to make the workers more convenient when rotating the driving shaft 21, the end surface of the connecting ring 33 is penetrated with two circular arc-shaped waist-shaped grooves 331, the circular arc axes of the waist-shaped grooves 331 are coincident with the axes of the connecting ring 33, and the fastening bolts 34 respectively penetrate through the two waist-shaped grooves 331 and slide in the waist-shaped grooves 331.

As shown in fig. 3, because the space between the inner wall of the connecting sleeve 25 and the outer wall of the screw rod is smaller, in order to make the process of inserting the screw rod into the connecting sleeve 25 more convenient, the end surface of the connecting ring 33 away from the mounting block 1 is coaxially provided with a limiting groove 332, and the outer wall of the connecting ring 33 is penetrated by the limiting groove 332. When the connecting ring 33 is connected with the machine tool, the inner wall of the limiting groove 332, which is close to the axis of the connecting ring 33, can be abutted against the inner wall of the supporting frame. The position of the rotating mechanism is limited by the limit groove 332, so that the axis of the connecting sleeve 25 can be kept coincident with the axis of the screw rod, and the end surface of the screw rod can not directly contact with the end surface of the connecting sleeve 25 when the screw rod is inserted into the connecting groove 251, and the process of inserting the screw rod into the connecting groove 251 is more convenient.
As shown in fig. 3, the rotation of the driving shaft 21 is difficult because there is no point where the driving shaft 21 can be directly forced when it is directly rotated. Therefore, one end of the driving rotating shaft 21 far away from the driving gear 22 connected with the driving rotating shaft is connected with a cross rod 11, and one end of the cross rod 11 far away from the driving rotating shaft 21 is rotatably connected with a handle 12. The handle 12 is utilized to rotate the driving rotating shaft 21, and a point capable of directly applying force is arranged in the rotating process, so that the driving rotating shaft 21 can rotate more conveniently.
As shown in fig. 3, since the spindle box has a large size and the mounting block 1 has a short length, the worker needs to extend his hand as much as possible to grasp the handle 12 when directly rotating the handle 12, and the detection process is troublesome. Therefore, the side wall of the cross rod 11, which is close to the driving rotating shaft 21, is welded with the extension rod 13, the extension rod 13 is sleeved on the driving rotating shaft 21, and the extension rod and the driving rotating shaft are fixedly connected through bolts. The handle 12 is located at a position far away from the mounting block 1 through the extension bar 13, so that the handle 12 is closer to the position of the observation dial gauge where a worker is located, and the worker can grasp the handle 12 more, so that the driving rotating shaft 21 rotates, and the detection process is more convenient.
Working principle:

The screw rod and the connecting sleeve 25 are kept fixed by rotating the fastening bolt, and at the moment, the screw rod can be driven to rotate by rotating the handle 12 so as to detect parallelism.
