English translation of the [Chinese original](), translated on 2026-11-15. Original publication dates, attribution, code and version notes are retained. An adjustable wrench combines a fixed jaw and a jaw sliding in a guide, rather than two pivoting plier handles. Draw an empty oblique exterior view in Aquarell, checking continuous head/handle, opposing jaws and adjustment placement, without a nut or force demonstration. ## Set the continuous handle-to-head direction Use an approximately 1700×1500 px canvas with handle lower left and head upper right, fully visible. Sketch handle axis, head envelope and two contact lines. A modest head offset is fine, but not a floating component. Unite spoon-like pieces into one body and remove a second long handle if it resembles pliers. Pixels and tilt are composition choices, not measured length, standard angle or an inferred operating direction. ## Keep the fixed jaw integral to the head Extend the fixed jaw from one side of the head with a continuous back contour and flat inner face. Check its integral form in one colour rather than adding screws across continuous material. Widen a tooth-like root and reopen a closed-loop gap. Perspective may narrow the face but must not twist head sides into incompatible views. This general exterior is not a precise manufacturer profile; omit unchosen serrated or pipe-jaw features. ## Give the movable jaw an independent sliding path Place the opposing movable jaw with its base entering a head guide rather than rotating about a handle-root knob. A short guide line may indicate sliding on a checking layer, not an exported rod. Keep facing surfaces distinct even at small openings. Replace crossed-scissor geometry with one fixed and one sliding component; repair a floating jaw through basal insertion and overlap. This exterior explanation establishes no manufacturing tolerance or measured travel. ## Seat the adjustment worm inside the head window Draw a small adjustment window beside the movable-jaw base, with a short cylinder and a few oblique ridges. Let the window occlude it rather than floating a whole wheel outside the handle. Place it correctly before texture; shorten any shaft apparently crossing both jaws. Do not expose every hidden rack contact or prescribe turn directions without model/view verification. This locates exterior parts, not a repair or dismantling procedure. ## Check opposing faces through the empty gap Use warm-grey ground and a clean gap, with slightly stronger near metal edges and softer far edges. Dark shading must not weld the opposing faces into a solid hole. Recheck the chosen faces if the gap becomes a V rather than hiding it with a nut. Turn thickness planes with the head perspective, not uniformly with the canvas. Gap width is pictorial, without millimetre graduations that imply a gauge or measured opening. ## Distinguish the handle hole from the jaw opening Optionally add one closed hanging hole in the handle end, exposing ground within metal thickness. It is distinct from the open jaw; no dark slot should connect them along the handle. Taper smoothly and use restrained longitudinal highlights, not identical white patches for window, hole and shine. Close an accidental end notch if it looks like another jaw, and restore ground in a solid hole. Omit lettering and let body continuity precede texture. ## Audit one body plus the movable component Hide highlights and ridges. Trace handle end to fixed jaw continuously, then movable face through its base into the guide. Remove plier-like second handles or large pivots at the sketch stage rather than concealing them with metal colour. Restore the window without hidden worm edges. Revise one identified fault, such as outward-facing jaw or floating window, then reduce again. Static continuity proves no smooth real adjustment; guide lines are not automatically computed motion. ## Reopen and verify fixed and movable identities Save native work, hide guides and export PNG. Reopen to identify one handle, fixed/movable faces and the window, then enlarge for insertion and hanging-hole occlusion. Reduce a black-hole window’s contrast rather than expanding it over the head. Remove stray checking layers in the original and reopen editable components. Note the empty general-jaw study and inspect specialised models separately. Success concerns ownership and gaps, not measured opening, torque, repair or automatic mechanical assembly. ## Related tutorials and sources [Draw pliers in Aquarell: turn both halves around one pivot](); [Draw a vernier caliper in Aquarell: align fixed and sliding jaws on one beam]().
