[0034] Specifically, in combination with Figure 1 and Figure 2As shown, the frame 110 is provided with a mounting hole; the measuring rod 120 is movably inserted through the mounting hole; the anvil 130 is disposed opposite to the measuring rod 120; the adjusting assembly 140 includes a clamping member 141 and an adjusting member 142. The clamping member 141 is sleeved on the measuring rod 120, and the clamping member 141 is disposed between the measuring rod 120 and the frame 110. The adjusting member 142 is movably connected to one end of the clamping member 141. When the adjusting member 142 adjusts the clamping member 141, the clamping member 141 can clamp the measuring rod 120. The measuring rod 120 can be adjusted by the adjusting member 142 so that the measuring rod 120 moves relative to the mounting hole to adjust the relative distance between the measuring rod 120 and the anvil 130. The object to be measured is placed between the measuring rod 120 and the anvil 130. The adjusting member 142 measures the size of the object to be measured by clamping the measuring rod 120 through the clamping member 141, avoiding the situation that the measuring rod 120 is eccentric or misaligned due to radial force, and reducing the situation that the measuring surfaces of the measuring rod 120 and the anvil 130 are not parallel. Exemplarily, the measuring rod 120 can be a micrometer screw.

[0035] It can be understood that the anvil 130 generally serves as a stable base for supporting the fixed end of the object to be measured or the measuring tool, ensuring the stability and accuracy of the measurement.

[0036] It should be noted that referring to Figure 1 As shown, the micrometer 100 has a first direction. Exemplarily, the first direction is taken as the length direction of the micrometer 100. It can be understood that the above definition is only for facilitating the understanding of the relative position relationship of each part in the micrometer 100 and should not be construed as a limitation to the present application.

[0037] In one embodiment, optionally, as Figure 2 shown, the clamping member 141 includes a first clamping portion 1411 and a second clamping portion 1412. Along the first direction, the first clamping portion 1411 and the second clamping portion 1412 are respectively disposed on opposite sides of the measuring rod 120, so that the adjusting member 142 is respectively in movable abutment with the first clamping portion 1411 and the second clamping portion 1412. The first clamping portion 1411 and the second clamping portion 1412 can be adjusted by the adjusting member 142 to enable the clamping member 141 to clamp or loosen, achieving the purpose of adjusting the measuring rod 120.

The positions of the first clamping portion 1411 and the second clamping portion 1412 are limited by the fixing bolts. The adjusting member 142 can finely adjust the gap between the first clamping portion 1411 and the second clamping portion 1412 to achieve the purpose of enabling the measuring rod 120 to move. After the measuring rod 120 abuts against the item to be measured, the first clamping portion 1411 and the second clamping portion 1412 are clamped by the adjusting member 142.

[0039] Optionally, referring to Figure 3 As shown, the adjusting member 142 defines an installation groove 1421. The first clamping portion 1411 and the second clamping portion 1412 are both inserted into the installation groove 1421. The first clamping portion 1411 abuts against the groove wall of the installation groove 1421, and the second clamping portion 1412 abuts against the groove wall of the installation groove 1421. That is, the clamping member 141 is limited by the groove wall of the installation groove 1421, and a certain adjustment space can be reserved between the first clamping portion 1411 and the second clamping portion 1412.

[0040] Optionally, in combination with Figure 1 and Figure 2 As shown, when the adjusting member 142 rotates in the first rotation direction, the adjusting member 142 locks the clamping member 141, and the clamping member 141 can clamp the measuring rod 120; when the adjusting member 142 rotates in the second rotation direction, the adjusting member 142 can loosen the clamping member 141, and the measuring rod 120 can move relative to the clamping member 141. The first rotation direction is opposite to the second rotation direction.

[0041] The micrometer 100 can adjust the measuring rod 120 through the adjusting member 142, so as to enable the measuring rod 120 to move relative to the installation hole, adjust the relative distance between the measuring rod 120 and the anvil 130. Place the item to be measured between the measuring rod 120 and the anvil 130. The adjusting member 142 measures the size of the item to be measured by clamping the measuring rod 120 through the clamping member 141, avoiding the situation that the measuring rod 120 is eccentric or displaced due to radial force, reducing the situation that the measuring surfaces of the measuring rod 120 and the anvil 130 are not parallel, and thus improving the measuring accuracy of the micrometer 100.

[0042] Embodiment 2

[0043] Referring to Figures 1 to 3As shown, an embodiment of the present application provides another micrometer 100, which includes a frame 110, a measuring rod 120, an anvil 130, and an adjusting assembly 140.

[0044] Specifically, as shown in combination with Figure 1 and Figure 2 The frame 110 is provided with a mounting hole; the measuring rod 120 is movably inserted through the mounting hole; the anvil 130 is disposed opposite to the measuring rod 120; the adjusting assembly 140 includes a clamping member 141 and an adjusting member 142. The clamping member 141 is sleeved on the measuring rod 120, and the clamping member 141 is disposed between the measuring rod 120 and the frame 110. The adjusting member 142 is movably connected to one end of the clamping member 141. The item to be measured is placed between the measuring rod 120 and the anvil 130. The adjusting member 142 measures the size of the item to be measured by clamping the measuring rod 120 through the clamping member 141.

[0045] In this embodiment, when the adjusting member 142 adjusts the clamping member 141, the clamping member 141 can clamp the measuring rod 120. The adjusting member 142 can adjust the measuring rod 120 to facilitate the movement of the measuring rod 120 relative to the mounting hole, so as to adjust the relative distance between the measuring rod 120 and the anvil 130, avoid the situation that the measuring rod 120 is eccentric or misaligned due to radial force, and reduce the situation that the measuring surfaces of the measuring rod 120 and the anvil 130 are not parallel. Exemplarily, the measuring rod 120 can be a micrometer screw.

[0046] It should be noted that, as shown in reference to Figure 1 This micrometer 100 has a first direction. Exemplarily, the first direction is taken as the length direction of the micrometer 100.

[0047] In one embodiment, optionally, as shown in Figure 2 The clamping member 141 includes a first clamping portion 1411 and a second clamping portion 1412. Along the first direction, the first clamping portion 1411 and the second clamping portion 1412 are respectively disposed on opposite sides of the measuring rod 120, so that the adjusting member 142 is respectively in movable abutment with the first clamping portion 1411 and the second clamping portion 1412. The first clamping portion 1411 and the second clamping portion 1412 can be adjusted through the adjusting member 142, so that the clamping member 141 can clamp or loosen, achieving the purpose of adjusting the measuring rod 120. Exemplarily, the first clamping portion 1411 and the second clamping portion 1412 jointly define a cylindrical cavity to facilitate the measuring rod 120 to pass through the cylindrical cavity of the clamping member 141.

[0048] Optionally, one end of the first clamping portion 1411 away from the adjusting member 142 is hinged to one end of the second clamping portion 1412 away from the adjusting member 142, that is, the first clamping portion 1411 can be movable relative to the second clamping portion 1412, so as to have a certain gap between the first clamping portion 1411 and the second clamping portion 1412. The measuring rod 120 is placed in the gap, so as to be adjusted by the adjusting member 142 to reduce the gap between the first clamping portion 1411 and the second clamping portion 1412, clamp the measuring rod 120, and realize the limiting and positioning of the measuring rod 120.

[0049] Optionally, referring to Figure 3 As shown, the adjusting member 142 defines an installation groove 1421. Both the first clamping portion 1411 and the second clamping portion 1412 are inserted into the installation groove 1421. The first clamping portion 1411 abuts against the groove wall of the installation groove 1421, and the second clamping portion 1412 abuts against the groove wall of the installation groove 1421. That is, the clamping member 141 is limited by the groove wall of the installation groove 1421, and a certain adjustment space can be reserved between the first clamping portion 1411 and the second clamping portion 1412. Further, a limiting boss is provided at the position of the groove wall of the installation groove 1421. Both the first clamping portion 1411 and the second clamping portion 1412 are provided with clamping portions, and the clamping portions are clamped to the limiting boss, so that the first clamping portion 1411 and the second clamping portion 1412 are respectively clamped to the groove wall of the installation groove 1421.

[0050] Optionally, the adjusting member 142 is in threaded connection with the clamping member 141. It can be understood that the threaded connection is a mechanical connection method, and the fastening and positioning of parts are realized by the mutual screwing of the threads of the clamping member 141 and the adjusting member 142. It has the characteristics of simple structure, convenient installation and disassembly, and good reliability. The clamping member 141 and the adjusting member 142 are used in cooperation. By adjusting the adjusting member 142, the clamping tightness of the clamping member 141 can be adjusted, and the adjusting member 142 and the clamping member 141 can be screwed together by rotating the adjusting member 142.

[0051] Optionally, in combination with Figure 1 and Figure 2As shown, when the adjusting member 142 rotates in the first rotation direction, the adjusting member 142 locks the clamping member 141, and the clamping member 141 can clamp the measuring rod 120; when the adjusting member 142 rotates in the second rotation direction, the adjusting member 142 can release the clamping member 141, and the measuring rod 120 can move relative to the clamping member 141. The first rotation direction is opposite to the second rotation direction. Exemplarily, the first rotation direction is the clockwise direction, and the second rotation direction is the counterclockwise direction. Rotating the adjusting member 142 clockwise can lock the clamping member 141, and rotating the adjusting member 142 counterclockwise can release the clamping member 141.

[0052] Optionally, the rotation axis of the adjusting member 142 is perpendicularly arranged with respect to the length direction of the measuring rod 120, that is, the axial direction of the rotation axis of the adjusting member 142 is perpendicular to the first direction. The length direction of the measuring rod 120 is the first direction. When the measuring rod 120 moves, the measuring rod 120 can move along the first direction to abut against the item to be measured, completing the measurement process of the item to be measured.

[0053] Furthermore, the adjusting member 142 is a rotary wrench. The rotary wrench is used to tighten or loosen the clamping member 141. In this application, using a rotary wrench as the adjusting member 142 can be applicable to occasions with limited space or requiring rapid rotation.
