Technical Field
[0001] The utility model relates to the technical field of fine-tuning tools, in particular to a fine-tuning screw and a wrench. Background Art
[0002] During the production and testing process, precise fine-tuning of the screws of the device is a crucial technical activity. Fine-tuning screws are widely used in situations that require precise adjustment due to their higher torque transmission capacity and more compact space occupancy. However, although commonly used fine-tuning screws can provide higher clamping force, they often lack intuitive adjustment distance indication when fine-tuning is required. This makes it difficult to control the adjustment accuracy during the adjustment process, and it is also difficult to quantify the specific adjustment distance, thus affecting the efficiency and quality of production and testing.
[0003] Therefore, the technical problems that the adjustment accuracy of traditional fine-tuning screws is difficult to control and the adjustment distance is difficult to quantify during fine-tuning are urgently needed to be solved in our production process. Utility Model Content

[0009] As a preferred solution, the handle is transversely fixed on the side of the connecting rod to form an L-shaped wrench.
[0010] As a preferred solution, the length ratio of the connecting rod to the handle is 1 to 3.
[0011] The beneficial effects of the utility model are:

[0020] To illustrate the features of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.
[0021] Example:
[0022] See also Figures 1 to 3The present embodiment provides a fine-tuning screw, including a screw head 1 and a screw rod 2. The screw head 1 is a hexagonal screw head. Four vertical first scales 3 are arranged on the side of the screw head 1. It is particularly noted that the reading of the first scale 3 is the height of the top surface of the screw head 1 above the surface of the fixed device, which is convenient for the operator to determine the adjustment position according to the current insertion distance. In order to avoid observation errors when reading, the present embodiment evenly distributes four planes on the side of the screw head 1, and sets the first scale 3 on the plane, which effectively avoids observation errors.
[0023] In addition, the present embodiment also provides a wrench for use with the above-mentioned fine-tuning screw, including a handle 4, a connecting rod 5 and a head 6. The handle 4 is fixedly arranged at the top end of the connecting rod 5, and the head 6 is fixedly arranged at the bottom end of the connecting rod 5. The head 6 is adapted for use with the screw head 1. The height of the head 6 is equal to the depth of the hexagonal hole of the screw head 1. The handle 4 is laterally fixedly arranged on the side of the connecting rod 5 to form an L-shaped wrench. The length ratio of the connecting rod 5 to the handle 4 is 1.5, which makes it more convenient for the operator to exert force when using it.
[0024] The core point of the wrench improvement provided in this embodiment is that a second scale 7 is provided on the side of the bottom end of the connecting rod 5. The position of the second scale 7 corresponds to the first scale 3, and the 0 points of the two coincide. The readings of the second scale 7 and the readings of the first scale 3 take the coincidence point as the 0 point, and continuously increase in their respective directions. The advantage of this setting is that by integrating a continuous scale on the screw head and the wrench, the adjustment accuracy is greatly improved, allowing the operator to fine-tune the screw through intuitive scale readings to ensure that each adjustment can reach the expected precise position. This improvement in accuracy is crucial for mechanical structures and equipment that require fine adjustment, because it can ensure precise matching between components, thereby improving the performance and reliability of the overall equipment. When the screw is completely immersed in the screw hole, the current screw depth can still be determined by reading the scale on the wrench.

The utility model is described in detail with reference to the preferred embodiments.
