Loosen the locking bolt close to the sleeve and slide the connecting rod downward to facilitate drawing vertical lines.

[0012] Specifically, an anti-slip sleeve is fixed on the handle, and anti-slip patterns are provided on the two knobs.

[0013] By adopting the above technical solution, the provision of the anti-slip cover makes it easy to hold, and the anti-slip pattern on the knob makes it easy to rotate the knob.
