Description

Technical Field

[0001] This utility model belongs to the field of line drawing devices, and specifically relates to a brow line drawing device. Background Technology

[0002] The main function of a wheel arch line marker is to help with precise positioning and line marking when repairing car dents. Traditional wheel arch line markers use bolts to fix the position of the middle cylinder, which requires the bolts to squeeze the main body of the screw to lock the middle cylinder. Prolonged use may damage the screw. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a brow line drawing tool.

[0004] The purpose of this utility model can be achieved through the following technical solution: a wheel eyebrow line drawer, including a screw, a middle cylinder that can move up and down on the screw, and a pen holder installed above the screw, characterized in that an adjustment knob is provided below the middle cylinder, the adjustment knob has a sliding groove, a sliding block that can slide up and down is provided in the sliding groove, and an inner cylinder surrounding the outer ring of the screw is provided at the upper end of the sliding block.

[0005] The inner cylinder is provided with limiting discs at both the upper and lower ends for cooperating with the middle cylinder for limiting, and the middle cylinder is provided with a groove for the limiting discs to rotate.

[0006] The upper end of the screw is provided with a locking nut for locking the inner cylinder together with the adjusting knob.

[0007] The aforementioned eyebrow liner is characterized in that a slot is provided below the middle cylinder, and a buckle is provided above the adjustment knob.

[0008] The aforementioned wheel arch liner is characterized in that a roller for conforming to the wheel arch is provided on the central cylinder.

[0009] The aforementioned eyebrow line drawer is characterized in that the pen holder has a threaded hole for screwing in a bolt to lock the drawing pen.

[0010] The aforementioned wheel brow liner is characterized in that the inner cylinder is provided with a thread that meshes with the screw.

[0011] Compared with existing technologies, this wheel brow line painter adjusts the middle cylinder by cooperating with the adjusting knob and the locking nut, avoiding the traditional wheel brow line painter's method of locking the middle cylinder by squeezing the screw, thus reducing damage to the screw.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 As shown, this eyebrow drawing tool includes a screw 1, a middle cylinder 2 that can move up and down on the screw 1, and a pen holder 3 installed above the screw 1. An adjustment knob 4 is provided below the middle cylinder 2. The adjustment knob 4 has a sliding groove 5 inside. A sliding block 6 that can slide up and down is provided in the sliding groove 5. An inner cylinder 7 that surrounds the outer ring of the screw 1 is provided at the upper end of the sliding block 6.

[0017] The inner cylinder 7 is provided with a limiting disc 8 at both the upper and lower ends for cooperating with the middle cylinder 2. The middle cylinder 2 is provided with a groove 9 for the limiting disc 8 to rotate. The upper end of the screw 1 is provided with a locking nut 10 for locking the inner cylinder 7 together with the adjusting knob 4.

[0018] When in use, turn the adjustment knob 4. The adjustment knob 4 will drive the inner cylinder 7 to rotate and move up and down along the screw 1. After adjusting to the desired position, turn the locking nut 10 downward until it fits against the middle cylinder 2 to lock the middle cylinder 2.

[0019] To elaborate further, a slot 11 is provided at the bottom of the middle tube 2, and a buckle 12 is provided above the adjustment knob 4. After the middle tube 2 is locked, the buckle 12 engages with the slot 11. Since the adjustment knob 4 is locked and cannot be rotated at this time, the middle tube 2 cannot be rotated after the buckle 12 engages with the slot 11.

[0020] To elaborate further, the middle cylinder 2 is equipped with a roller 13 for fitting the wheel arch.

[0021] To elaborate further, the pen holder 3 has a threaded hole 14 for screwing in a bolt to lock the drawing pen.

[0022] To elaborate further, the inner cylinder 7 is provided with threads that mesh with the screw 1.

[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0024] Although this document frequently uses terms such as screw 1, middle cylinder 2, pen holder 3, adjusting knob 4, sliding groove 5, sliding block 6, inner cylinder 7, limiting disc 8, channel 9, locking nut 10, slot 11, buckle 12, roller 13, and threaded hole 14, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
