[0028] In this embodiment, the top end of the sleeve member 4 is integrally connected with an external threaded joint 16, and a detachable top cap 11 is threadedly connected to the external threaded joint 16, and the upper anchor member 3 is sleeved from the bottom end of the sleeve member 4.

At the same time, a first positioning through hole 17 is arranged at the middle position of the top surface of the detachable top cap 11, allowing the measurement scale 6 to pass through.

[0029] In this embodiment, the positioning assembly 9 includes two positioning vertical rods 14 symmetrically welded to the top surface of the detachable top cap 11, and a positioning block 13 welded to the top end of the two positioning vertical rods 14, and the positioning block 13 and the detachable top cap 11 are arranged concentrically.

[0030] In this embodiment, the first positioning through hole 17 is arranged at the middle position of the top surface of the detachable top cap 11, and the second positioning through hole 18 is arranged at the middle position of the top surface of the positioning block 13.

[0031] In this embodiment, the measurement scale 6 is inserted into the sleeve member 4 through the second positioning through hole 18 and the first positioning through hole 17 in sequence, and the peripheral outer wall of the detachable top cap 11 has an anti-skid pattern 10.

[0034] Working principle:

[0035] The upper anchor exposed length controller first fixes the upper anchor plate 2 at the position where the upper anchor bolt 3 needs to be installed. Ensure that the upper anchor plate 2 is flat and stable. The support base 5 can be closely attached to the upper anchor plate 2, and the preliminary fixation is achieved through magnetic attraction. A plurality of upper anchor bolts 3 are arranged equidistantly and vertically inserted into the reserved holes on the upper anchor plate 2. Ensure that the bottom end of each upper anchor bolt 3 completely enters the inside of the upper anchor plate 2, and the top end is exposed to a certain length. The sleeve 4 is sleeved from the bottom end of the upper anchor bolt 3 upwards until the support base 5 closely adheres to the upper anchor plate 2. At this time, the annular magnet 12 is magnetically attracted to the upper anchor plate 2, further fixing the sleeve 4.

[0036] Take out the measuring scale 6, align the bottom end of the measuring scale 6 with the top opening of the sleeve 4, and vertically insert it into the sleeve 4. The bottom end of the measuring scale 6 should vertically touch the top surface of the upper anchor bolt 3, and the top end should pass through the first positioning through hole 17 and the second positioning through hole 18 in turn, and finally be located above the positioning block 13.

[0037] Through the positioning vertical rod 14 and the positioning block 13 in the positioning assembly 9, it is ensured that the measuring scale 6 always maintains a vertical state, preventing it from tilting or jamming. The design of the positioning assembly 9 can effectively limit the lateral movement of the measuring scale 6, ensuring the accuracy of the measurement. The compression spring 20 in the elastic compression assembly 8 exerts an elastic force through the support vertical rod 15 and the compression disc 7, so that the limiting disc 19 always closely adheres to the top end of the measuring scale 6. This design not only maintains the vertical position of the measuring scale 6, but also ensures that it will not loosen or shift during use.

[0038] When the measuring scale 6 is inserted into place, the operator can directly read the exposed length of the upper anchor bolt 3 by observing the scale line exposed outside the top end of the sleeve 4. The scale line has high precision and can provide accurate measurement results.

[0039] After completing the adjustment of the exposed length of the upper anchor bolt 3, the controller assembly 1 can be removed from the upper anchor bolt 3. Due to the design of the sleeve 4 and the detachable top cap 11, the whole process is simple and fast, and is convenient for repeated use.
