[0002] With the continuous improvement of people's living standards, people have higher and higher requirements for materials such as clothing and leather. At present, when cutting materials such as clothing and leather, a pen tool for a single-layer cutting bed is required, and the pen tool is used for scribing operations during material cutting. The existing pneumatic pen for a single-layer cutting bed mainly consists of a fixed seat, a pen core, a pen barrel, a solenoid valve, a cylinder, a sliding seat, etc., and it achieves the purpose of drawing lines by controlling the lifting of the cylinder. However, in the prior art, due to the different hardness and thickness of the materials to be cut, problems such as unclear scribing and too thick scribing are likely to occur when the pen scribes lines. To solve the above problems, every time the material is changed for cutting in the existing single-layer cutting bed, a large amount of time is required to readjust the pneumatic pen, which not only incurs a large economic cost but also affects the accuracy of the pneumatic pen.

[0005] After adopting the above structure, the nib on the refill can rely on the elastic force of the spring to abut against the material to be scribed. And under the action of the spring, when the hardness or thickness of the material changes, the refill can float up and down, that is, the nib on the refill can float up and down, which means the nib can adapt to the change of the hardness or thickness of the material. Thus, it can avoid the problems of unclear scribing or too thick scribing when the refill is scribing, and can avoid affecting the accuracy of the pneumatic pen; in addition, after the material is replaced, there is no need to adjust the height of the pen, which can improve production efficiency and avoid unnecessary economic losses.

After adopting the cylinder as the driving component, it has the advantage of simple structure of the driving component. When the piston rod of the cylinder expands and contracts, the cylinder can reliably drive the sliding seat to slide vertically.
[0011] In a possible implementation, a buffer block is fixed to the lower end of the sliding seat. When the sliding seat slides upward and resets, the buffer block is used to abut against the lower end of the bracket. Through the setting of the buffer block, when the cylinder drives the sliding seat to slide upward and reset, the buffer block can finally abut against the lower end of the bracket, so as to play a buffering role for the sliding seat, eliminate the impact abnormal sound between the sliding seat and the bracket, and avoid the situation of impact damage between the sliding seat and the bracket.
[0012] In a possible implementation, the pneumatic pen further includes a tension spring. The two ends of the tension spring are respectively hooked to the sliding seat and the bracket, and the tension spring is used to apply a pulling force to the sliding seat to drive the sliding seat to move upward. Through the setting of the tension spring, the tension spring can always apply a pulling force to the sliding seat, so as to apply a certain tension to the sliding seat. When the cylinder drives the sliding seat to slide vertically, the sliding process of the sliding seat can be made smoother. In addition, when the cylinder drives the sliding seat to slide upward and reset, the tension spring can assist the sliding seat to slide upward and reset, that is, the process of the sliding seat sliding upward and resetting can be made smoother.

[0021] See Figures 1-4 As shown, the embodiments of the present application disclose a pneumatic pen with automatically adjustable height for a single-layer cutting table, which includes a bracket 1, a sliding seat 2, a driving assembly and a pen core 3; the bracket 1 is used to be fixed on the moving driving end of the single-layer cutting table, the sliding seat 2 is vertically slidably connected to the bracket 1, the driving assembly is installed on the bracket 1 and is used to drive the sliding seat 2 to slide vertically; the pneumatic pen further includes a pen barrel 4, an end cap 5 and a spring 6; the pen barrel 4 is vertically fixed on the sliding seat 2, the pen core 3 is arranged inside the pen barrel 4, the pen tip 31 on the pen core 3 vertically penetrates the lower end of the pen barrel 4 and extends out of the pen barrel 4, an annular step 32 is arranged on the outer peripheral wall of the pen tip 31, the annular step 32 abuts against the inner bottom of the pen barrel 4, the end cap 5 is threadedly connected to the opening at the upper end of the pen barrel 4, the spring 6 is arranged inside the pen barrel 4 and the two ends of the spring 6 respectively abut against the end cap 5 and the upper end of the pen core 3, and the spring 6 is used to apply a thrust force to the pen core 3 to drive the pen core 3 to move downward.
[0022] When the present utility model is in operation, the driving assembly can drive the sliding seat to slide downward so that the pen tip on the pen core abuts against the material. In this state, when the moving driving end of the single-layer cutting table drives the bracket to move horizontally, the pen core can draw a line on the material.

[0028] A buffer block 12 is fixed to the lower end of the sliding seat 2. When the sliding seat 2 slides upward and resets, the buffer block 12 is used to abut against the lower end of the bracket 1.
