The marking pen is descended through the lifting assembly, so that the pen point of the marking pen is in contact with kraft paper, the gun head is driven by the multi-axis moving module, the marking pen is made to draw and mark on the kraft paper, an operator can conveniently obtain a paper sample, the number of overall equipment needing to be arranged is reduced, and the overall cost input is effectively reduced; and drawing is directly carried out on the cutting machine, so that the overall working efficiency can be improved, and manual participation is reduced.

This invention discloses a telescopic fountain pen, comprising a pen tip, a feed, a pen neck, a pen barrel, a pen cap, an ink reservoir, and a sealing bushing. The pen cap is slidably fitted onto the front end of the pen barrel, and the front end of the pen cap has a pen tip hole for the pen tip to extend out. The pen neck is disposed within the pen cap, and the rear end of the pen neck is detachably connected to the front end of the pen barrel. The ink reservoir is disposed within the pen barrel, and the front end of the ink reservoir is detachably connected to the rear end of the pen neck. The feed is inserted into the pen neck, and the front end of the feed extends out of the pen neck and connects to the pen tip. The pen neck has an ink inlet channel for injecting ink from the ink reservoir into the feed. The sealing bushing is fixed within the pen cap, and the sealing bushing is fitted around the outer periphery of the pen neck, with a dynamic sealing structure between the sealing bushing and the pen neck. The front end of the sealing bushing is a closed end, and the closed end has a self-closing slit for repeated insertion of the pen tip. A lower limit structure and an upper limit structure are provided between the pen cap and the pen neck. Using this invention, the problems of ink drying at the pen tip and uneven ink flow can be solved.

This utility model discloses a pull-type telescopic pen, including a pen barrel and a refill. The refill extends and retracts from the pen barrel via a telescopic locking mechanism. The telescopic locking mechanism includes a pressure rod and a locking element. The pressure rod pushes the locking element downwards to slide on a track inside the pen barrel. The pressure rod is located inside the pen barrel, and a pull tongue is fixed to the pressure rod, extending to the outside of the pen barrel and located on its vertical side. This utility model reduces the probability of the refill extending out of the pen barrel when the pressure rod is pressed by external force during storage by placing the pressure rod inside the pen barrel and the pull tongue fixedly connected to the pressure rod on the vertical side of the pen barrel.

This invention discloses a multifunctional retractable pen cap structure, including a pen cap and a retractable pen holder assembly. The pen holder assembly is located on the outside of the pen cap and is connected to a clamping assembly. The clamping assembly moves directionally along a limiting assembly, clamping the pen barrel and causing the pen holder assembly to retract. A locking assembly and a limiting assembly are fixedly connected to the clamping assembly and self-lock. In this invention, the clamping assembly drives the pen holder assembly to move, and the locking assembly and limiting assembly engage, enabling the pen holder assembly to retract or extend by closing and separating the pen barrel and pen cap. When extended, the pen holder assembly forms a support structure for placing and limiting the pen barrel; when retracted, it forms a clamping structure similar to existing technologies. The limiting assembly and locking assembly clamp and fix the pen holder assembly and pen barrel, improving the stability and robustness of the pen cap and pen barrel.

The utility model relates to the technical field of writing tools, and discloses a mute telescopic pen which comprises a pen holder, a positioning hole is formed in the right side of the pen holder, a pen cap is connected to the top of the pen holder in a threaded mode, a sliding column is connected into the pen cap in a sliding mode, and a lantern ring is fixedly connected to the middle of the sliding column. The bottom of the right side of the sliding column is fixedly connected with an elastic rod, the bottom of the right side of the elastic rod is fixedly connected with a protruding block, the bottom of the sliding column is fixedly connected with a hollow column, the bottom of the hollow column is fixedly connected with a spring, and the bottom of the spring is fixedly connected with a supporting column. According to the pen, the sliding column is pressed to drive the hollow column to descend, so that the elastic rod descends, the convex block extends out of the positioning hole, the fixing effect is achieved, when the pen does not need to be used, the convex block is pressed to push back the elastic rod, the hollow column bounces upwards under the action of the spring, the contraction effect is achieved, the pen can be protected, and the pen is convenient to store and carry.
