[0021] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0022] As Figures 1-4 shown, a pressure-resistant marker pen includes a pen body 1 and a pen cap 2. The pen body 1 is provided with a sealed end 13 and an open end 11 that communicate with each other. A pressure-resistant mechanism 3 is arranged on the pen body 1. The pressure-resistant mechanism 3 includes a plurality of elastic support strips 33 arranged in a circumferential array along the sealed end 13. A fiber composite core 31 inserted into the sealed end 13 is arranged inside the elastic support strip 33;

[0023] A tapered groove 131 is formed on the sealed end 13.

[0024] Specifically, a pigment cartridge is arranged inside the pen body 1. The open end 11 is one end of the pigment cartridge. The sealed end 13 is snap-fitted on the open end 11 for blocking the pigment cartridge. A tapered groove 131 is formed on the sealed end 13. A plurality of elastic support strips 33 are arranged on the tapered groove 131. The fiber composite core 31 is snap-fitted on the tapered groove 131. The fiber composite core 31 is wrapped and supported by the plurality of elastic support strips 33 to increase the pressure resistance of the fiber composite core 31. At the same time, the elastic elastic support strips 33 can be deformed to a certain extent when the fiber composite core 31 is pressed to maintain normal oil output.

[0025] In the above technical solution, the fiber composite core 31 is wrapped and supported by a plurality of elastic support strips 33 to increase the pressure resistance of the fiber composite core 31. A friction sleeve 32 is arranged outside the elastic support strip 33, and the replaceable friction sleeve 32 is used for outer friction replacement to increase the durability effect.

[0026] As a further embodiment provided by the present utility model, a friction sleeve 32 is sleeved outside the elastic support strip 33. Barbs 331 are arranged on the elastic support strip 33. The friction sleeve 32 is made of composite fiber. The friction sleeve 32 is sleeved before long-term use and fixed by the barbs 331 to reduce the wear on the fiber composite core 31. The friction sleeve 32 can be directly torn off and discarded for replacement after use.

[0027] As a further embodiment provided by the present utility model, the elastic support bars 33 are driven to approach the sealing end 13 to drive the plurality of elastic support bars 33 to close along the tapered groove 131. A hook end 332 is provided on the elastic support bar 33, and an opening groove 14 is formed on the sealing end 13. A moving bar 34 is slidably connected to the opening groove 14. A ring is provided on the moving bar 34. The moving bar 34 is driven to move to pull the hook end 332 through the ring, so as to move the elastic support bar 33. A sliding groove 12 for the moving bar 34 to slide is formed on the pen body 1, so as to move the moving bar 34 through the sliding groove 12, which is convenient for operation.

[0028] Working principle: When it is necessary to add pigments or for the first use, slide the moving bar 34 back and forth along the sliding groove 12, so that the plurality of elastic support bars 33 close or relax along the tapered groove 131, thereby driving the fiber composite core 31 to move and absorb pigments. When a large area of application is required, the elastic support bars 33 are kept in a relaxed state, and when fine painting is required, the elastic support bars 33 are kept in a closed state. At the same time, the plurality of elastic support bars 33 wrap the fiber composite core 31 for support, increasing the pressure resistance of the fiber composite core 31. When in use for a long time, a friction sleeve 32 is sleeved and fixed by the barbs 331.

[0029] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
