[0019] The utility model embodiment provides a silent writing ballpoint pen, such as Figure 1-3 As shown, it includes a shaft cylinder 11, a stop support 12, a pen core 13, a rebound component and a shaft sleeve 15, as shown in FIG. Figure 2 As shown, the stopper 12 is threadedly connected to one end of the shaft cylinder 11, the pen core 13 is arranged in the shaft cylinder 11, and the shaft sleeve 15 is arranged on the outer circumferential surface of the shaft cylinder 11, as shown in FIG. Figure 3 As shown, rubber pads 23 and cotton pads 24 are embedded on the inner and outer sides of the sleeve 15. The rubber pads 23 and the cotton pads 24 are both made of sound-proof cotton. The sleeve 15 is sleeved on the outer circumferential surface of the shaft tube 11 through the rubber pads 23, and the cotton pads 24 are sleeved on the outside of the sleeve 15. The outer circumferential surface of the shaft tube 11 is sleeved with anti-slip pads 18.

[0020] The shaft sleeve 15 is located at one end of the shaft tube 11 close to the rebound assembly.

[0021] Two buckle grooves 20 are defined in the shaft cylinder 11 , and the buckle grooves 20 are arranged along the axis direction of the shaft cylinder 11 .

[0022] The rebound assembly includes a press support 14, a pen clip 17 and a switching piece 21. The press support 14 and the switching piece 21 are both arranged in the shaft tube 11 (the same as the prior art structure). The press support 14, the switching piece 21 and the pen core 13 are arranged in sequence from top to bottom in the shaft tube 11. The switching piece 21 extends into one of the buckle grooves 20. A connecting rib 16 is fixedly provided on the outside of the shaft sleeve 15. The pen clip 17 is connected to the shaft sleeve 15 through the connecting rib 16. The lower end of the pen clip 17 is located in the same plane as the buckle groove 20 on the lower side.

[0023] The material of the pen clip 17 is elastic.

[0024] The user rotates the gear support 12 out of the barrel 11, takes out the refill 13 and replaces the refill 13 in the barrel 11 with its tail against the switch 21, and then rotates the gear support 12 into the barrel 11 to complete the replacement.

[0025] When the support 14 is pressed down, the support 14 drives the switching member 21 to move downward, the switching member 21 is located in the lower buckle groove 20, and the pen core 13 extends to the outside of the support 12. When the pen clip 17 is pressed, the pen clip 17 is against the switching member 21 located in the lower buckle groove 20, and the elastic member in the switching member 21 makes the switching member 21 rebound to the initial position. At this time, the pen core 13 rebounds into the shaft tube 11.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
