[0014] The shaft end or rod end to be adjusted extends into the cylindrical tube after passing through the wrench seat, the bearing seat, and the thrust bearing, and is locked with the cylindrical tube. The wrench seat slides away from the bearing seat so that the rubber ring is pressed against the square nut on the shaft end or rod end to be adjusted.
[0015] Preferably, the number of guide posts is at least two, and both of them penetrate the wrench holder so that the wrench holder can be slidably disposed along the axial direction.

The adjusting wrench is provided with an adjusting part that extends between the wrench seat and the bearing seat and abuts against both. The adjusting part rotates about the rotation axis of the adjusting wrench and drives the wrench seat away from the bearing seat, so that the rubber ring moves toward the square nut and is pressed.
[0017] Preferably, there are two adjusting wrenches, which are symmetrically arranged on both sides of the wrench seat, and the two adjusting wrenches are coaxially rotatably connected so that the two sides of the wrench seat move away from the bearing seat simultaneously.
[0018] Preferably, a spring is further provided between the bearing housing and the wrench seat, with both ends of the spring fixed to the bearing housing and the wrench seat respectively, and the spring is used to provide an elastic force for the wrench seat to move towards the bearing housing.

[0023] An adjustment method, implemented by using the manual fine adjustment device of any one of the above, comprising the steps of:
[0024] S1, placing the magnetic rotating needle at the zero scale of the dial, i.e. against the raised baffle;
[0025] S2, loosening the locking bolt, and rotating the adjustment ring to drive the locking bolt to rotate to the required angular scale, at this time the locking bolt and the raised baffle form the adjustable range of the magnetic rotating needle;
[0026] S3, tightening the locking bolt to relatively fix the adjustment ring and the annular member, rotating the rotating adjustment member, under the magnetic attraction between the magnetic rotating needle and the dial, the manual fine adjustment device rotates as a whole, and drives the shaft or rod to be adjusted to rotate, thus completing the coarse adjustment;
[0027] S4, moving the wrench seat to face the square nut at the end of the shaft or rod to be adjusted, so that the rubber ring is pressed on the square nut, at this time the wrench seat and the bearing seat remain stationary relative to the square nut;
[0028] S5, rotating the rotating adjustment member, under the friction force between the rubber ring and the square nut, overcoming the magnetic attraction between the magnetic rotating needle and the dial, so that the magnetic rotating needle slides relative to the dial, the magnetic rotating needle is adjusted within the adjustable range formed between the locking bolt and the raised baffle, thus completing the fine adjustment operation.
[0029] With respect to the above background technology, the present application connects the cylindrical barrel with the end of the shaft or rod to be adjusted, and realizes the adjustment of the shaft or rod by rotating the cylindrical barrel. The adjustment is divided into coarse adjustment and fine adjustment. When the wrench seat is separated from the square nut, i.e. there is a gap between the rubber ring and the square nut, at this time the device can be rotated as a whole by the magnetic attraction of the magnetic rotating needle, so as to perform the coarse adjustment operation on the shaft or rod. When the rubber ring on the wrench seat is pressed against the square nut, at this time the friction force between the rubber ring and the square nut is much greater than the magnetic attraction between the magnetic rotating needle and the dial, so as to force the two to produce sliding friction during the rotation of the cylindrical barrel, so that only the shaft or rod is rotated under the driving of the cylindrical barrel, and the scale of the dial can accurately record the adjustment degree, thus realizing the fine adjustment operation.
[0030] Furthermore, the application sets the locking bolt through the adjusting ring, and the locking bolt extends outside the adjusting ring, so that the locking bolt corresponds to the scale on the dial plate. When the adjusting ring rotates by a certain angle, the locking bolt forms a limiting area with the raised baffle on the dial plate, and the magnetic rotating needle can be adjusted in the area. Of course, the area can be changed according to the actual situation, so as to realize the quantization of the adjustment range.
[0031] Specifically, the manual fine adjustment device comprises a bearing assembly, a wrench seat, a dial plate, a range adjustment member and a rotation adjustment member. The bearing assembly comprises a bearing seat and a thrust bearing arranged in the bearing seat. The end face of the bearing seat is provided with a guide column. The wrench seat is located on one side of the bearing seat and is slidably connected with the bearing seat through the guide column. The end face of the wrench seat away from the bearing seat is provided with a rubber ring. The dial plate is fixedly arranged on the end face of the bearing seat away from the wrench seat. The dial plate is centrally provided with a circular ring. The zero scale of the dial plate is provided with a raised baffle. The range adjustment member comprises an adjusting ring rotatably arranged on the outer periphery of the circular ring and a locking bolt threadedly connected with the side wall of the adjusting ring. One end of the locking bolt penetrates the side wall of the adjusting ring and abuts against the outer periphery of the circular ring, so as to realize the tightness adjustment of the adjusting ring. The other end of the locking bolt extends outside the adjusting ring and forms an adjustable range with the raised baffle. The rotation adjustment member comprises a hollow cylindrical barrel and a magnetic rotating needle arranged outside the cylindrical barrel. The cylindrical barrel penetrates the circular ring and extends into the bearing seat to abut against the end face of the thrust bearing, so as to rotatably arrange the cylindrical barrel. The end of the magnetic rotating needle abuts against and magnetically attracts the dial plate. It should be noted that the shaft end or rod end to be adjusted penetrates the wrench seat, the bearing seat, the thrust bearing and extends into the cylindrical barrel, and is locked with the cylindrical barrel. The wrench seat slides away from the bearing seat, so that the rubber ring is pressed against the square nut of the shaft end or rod end to be adjusted. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0039] It should be noted that in the present embodiment, the directions or position relationships indicated by “up”, “down”, “front”, “back” and the like are the directions or position relationships shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, “first”, “second”, “third”, “fourth” are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0040] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.
[0041] Please refer to Figure 1 In the present embodiment, a manual fine adjustment device is provided, which comprises a bearing assembly 1, a wrench seat 2, a dial 3, a range adjustment piece 4 and a rotary adjustment piece 5. The bearing assembly 1 comprises a bearing seat 11 and a thrust bearing 12 arranged inside the bearing seat 11. Generally, the thrust bearing 12 has axial bearing capacity, thereby bearing the cylindrical barrel 53 and realizing the rotational arrangement of the cylindrical barrel 53.
[0042] The end face of the bearing seat 11 is provided with a guide column 13, and the wrench seat 2 is slidably connected with the bearing seat 11 through the guide column 13; that is, the wrench seat 2 can slide along the guide column 13 to approach or move away from the bearing seat 11. The end face of the wrench seat 2 away from the bearing seat 11 is provided with a rubber ring 22, and when the wrench seat 2 moves away from the bearing seat 11, the rubber ring 22 can be pressed on the square nut 9, so that the bearing seat 11 and the wrench seat 2 are stationary relative to the square nut 9.
[0043] The dial plate 3 is fixed on the end face of the bearing seat 11 away from the wrench seat 2, please refer to Figure 1 The dial plate 3 is provided with a circular ring 32 in the center, and a raised baffle 31 is arranged at the zero scale of the dial plate 3; the thickness of the raised baffle 31 is relatively thin, which does not affect the scale value at the zero scale.
[0044] The range adjusting part 4 includes an adjusting ring 41 rotatably sleeved on the outer periphery of the circular ring 32 and a locking bolt 42 threadedly connected with the side wall of the adjusting ring 41. One end of the locking bolt 42 penetrates through the side wall of the adjusting ring 41 and abuts against the outer periphery of the circular ring 32, and the other end extends out of the adjusting ring 41 and has a certain extension length, which can correspond to the scale on the dial plate 3. After the locking bolt 42 is rotated by a certain angle, an adjustable range can be formed between the locking bolt 42 and the raised baffle 31.
[0045] It should be noted that one function of the locking bolt 42 is to lock or loosen the adjusting ring 41 and the circular ring 32, and the other function is to determine the adjusting range of the magnetic rotating needle 51, that is, the adjustable range is formed between the locking bolt 42 and the raised baffle 31, so as to form a visual or quantitative adjusting range.
[0046] Please refer to Figure 1 The rotating adjusting part 5 includes a hollow cylindrical barrel 53 and a magnetic rotating needle 51 arranged on the outer side of the cylindrical barrel 53. The cylindrical barrel 53 penetrates through the circular ring 32 and extends into the bearing seat 11 to abut against the end face of the thrust bearing 12, so that the cylindrical barrel 53 is rotatably arranged. The end of the magnetic rotating needle 51 abuts against and magnetically attracts the dial plate 3. Through the magnetic attraction force between the two, the overall rotation of the device can be maintained.
[0047] And the shaft end or rod end to be adjusted penetrates through the wrench seat 2, the bearing seat 11, the thrust bearing 12 and extends into the cylindrical barrel 53, and is locked with the cylindrical barrel 53. When the wrench seat 2 slides away from the bearing seat 11, the rubber ring 22 can be pressed on the square nut 9 of the shaft end or rod end to be adjusted. At this time, the friction force between the rubber ring 22 and the square nut 9 can overcome the magnetic attraction force between the magnetic rotating needle 51 and the dial plate 3, so that when the cylindrical barrel 53 is rotated, the magnetic rotating needle 51 and the dial plate 3 will slide, and the fine adjustment operation can be realized.
[0048] In combination with the above embodiments, the present application is connected with the shaft end or rod end to be adjusted by the cylindrical barrel 53, and the adjustment of the shaft or rod is realized by rotating the cylindrical barrel 53. The adjustment is divided into coarse adjustment and fine adjustment. When the wrench seat 2 is separated from the square nut 9, i.e. there is a gap between the rubber ring 22 and the square nut 9, at this time, the cylindrical barrel 53 can be rotated, the magnetic attraction of the magnetic rotating needle 51 drives the whole device to rotate, thereby the shaft or rod is coarsely adjusted. When the rubber ring 22 on the wrench seat 2 is pressed against the square nut 9, at this time, the friction force between the rubber ring 22 and the square nut 9 is much greater than the magnetic attraction between the magnetic rotating needle 51 and the dial 3, thereby in the process of rotating the cylindrical barrel 53, the sliding friction between the two is forced, thereby the shaft or rod is only rotated under the drive of the cylindrical barrel 53, and the scale of the dial 3 can accurately record the adjustment degree, thereby the fine adjustment is realized.
[0049] It should be noted that the number of guide columns 13 is at least two, and they all penetrate the wrench seat 2, thereby ensuring that the wrench seat 2 can be stably arranged in the axial sliding manner along the guide column 13.
[0050] The end surface of the wrench seat 2 facing the bearing seat 11 is provided with a support 21, the adjusting wrench 6 is arranged in a rotating manner on the support 21, the adjusting wrench 6 is provided with an adjusting part extending into and abutting against the wrench seat 2 and the bearing seat 11, and the adjusting part can be an eccentric structure. When the adjusting part rotates around the rotating shaft of the adjusting wrench 6 as the axis, the wrench seat 2 is driven to move away from the bearing seat 11, thereby the wrench seat 2 is arranged in the up-down sliding manner, the rubber ring 22 is forced to move towards and press against the square nut 9.
[0051] Similarly, in order to ensure the sliding stability of the wrench seat 2, the number of adjusting wrenches 6 is also set to two, and they are symmetrically arranged on both sides of the wrench seat 2. The two adjusting wrenches 6 can be coaxially and rotationally connected through a light rod, thereby realizing the synchronous movement of the wrench seat 2 away from the bearing seat 11 on both sides.
[0052] Please refer to Figure 1 The spring 7 is arranged between the bearing seat 11 and the wrench seat 2, and can be arranged on the side of the bearing seat 11 and the wrench seat 2 or between the two, which is not limited here. When the spring 7 is arranged on the side of the bearing seat 11 and the wrench seat 2, it can be fixed through a bolt, thereby ensuring that the two ends of the spring 7 can be fixed with the bearing seat 11 and the wrench seat 2. The spring 7 can provide elasticity for the movement of the wrench seat 2 towards the bearing seat 11. When the wrench seat 2 needs to move towards the bearing seat 11, the adjusting wrench 6 is only needed to be rotated, so that a certain space is left between the adjusting part and the bearing seat 11, thereby under the action of the spring 7, the wrench seat 2 is driven to move towards the bearing seat 11, and the rubber ring 22 is separated from the square nut 9.
[0053] And the number of spring 7 is at least two, and the part is divided between bearing seat 11 and wrench seat 2, so that the wrench seat 2 is subjected to evenly distributed elastic force, ensuring that the wrench seat 2 can move more stably when facing the bearing seat 11.
[0054] In addition, the rotary adjusting part 5 further comprises a knob 54 sleeved on the outer periphery of the cylindrical barrel 53, the knob 54 rotates synchronously with the cylindrical barrel 53; the outer wall of the cylindrical barrel 53 is provided with a connecting rod 52, the connecting rod 52 is provided with a magnetic rotating needle 51 at the end away from the cylindrical barrel 53, and the knob 54 is provided with a notch for clamping the connecting rod 52, so that the knob 54 drives the cylindrical barrel 53 to rotate synchronously through the connecting rod 52.
[0055] It should be noted that the sidewall of the cylindrical barrel 53 is provided with a through wire hole, and a jack screw for pressing the shaft end or rod end to be adjusted is arranged in the wire hole, so that the locking operation can be completed when the shaft end enters the cylindrical barrel 53.
[0056] When the device is assembled, the thrust bearing 12 is first installed in the bearing seat 11, the cylindrical barrel 53 is on the thrust bearing 12, and then the dial 3 is bolted with the bearing seat 11; the adjusting ring 41 is sleeved, at this time the magnetic needle on the magnetic rotating needle 51 and the connecting rod 52 part are bolted with the cylindrical barrel 53. The knob 54 is sleeved on the cylindrical barrel 53 and the jack screw is tightened to make it relatively fixed. The adjusting wrench 6 is arranged on the support 21, so that the two wrenches keep synchronous movement. The guide column 13 is used between the wrench seat 2 and the bearing seat 11 to form a relative movement structure, and the wrench seat 2 can slide on the guide column 13. The spring 7 is bolted on the wrench seat 2 and the bearing seat 11, wherein the bolt on the bearing seat 11 is longer for locking the guide column 13, the bolt on the wrench seat 2 is shorter and does not contact the guide column 13, and the rubber ring 22 at the bottom of the wrench seat 2 is glued with the wrench seat 2.

[0061] S4, moving the wrench seat 2 to face the square nut 9 of the lead screw 8, so that the rubber ring 22 is pressed on the square nut 9, at this time the wrench seat 2 and the bearing seat 11 keep still relative to the square nut 9;
[0062] S5, rotating the rotation adjusting part 5, under the friction force of the rubber ring 22 and the square nut 9, overcoming the magnetic attraction force between the magnetic rotating needle 51 and the dial 3, so that the magnetic rotating needle 51 slides relative to the dial 3, the magnetic rotating needle 51 is adjusted within the adjustable range formed between the locking bolt 42 and the convex baffle 31, thus completing the fine adjustment operation, for details, please refer to Figure 3 At this time, the rubber ring 22 is pressed on the square nut 9.
