The structure of the pair of retaining parts 5 is completely the same, wherein the matching modes of the polygonal slot 51, the limiting stopper 52 and the retaining part protrusion 31 covered by any pair of pressing mechanisms are as follows: the limiting stop piece 52 is located in the middle area of the polygonal clamping groove 51, when the pen holder barrel part 3 and the front pen barrel part 1 move axially mutually, the clamping piece protrusion 31 is clamped into the limiting stop piece 52, the pen holder barrel part 3 and the front pen barrel part 1 are in a first stage of axial relative approach, and the pen core 2 is in an exposed state. When the clamping piece protrusion 31 is separated from the limiting stop piece 52 and the penholder barrel part 3 and the front penholder barrel part 1 are in the second stage of axial separation, the pen core 2 is in a hidden state. The invention is within the scope of the invention as long as the position-limiting stopper 52 is located in the polygonal slot 51, so that the card member protrusion 31 has the above two states.
For those skilled in the art, when the first stage that the barrel part 3 and the front barrel part 1 are relatively close to each other in the axial direction is realized, the catching protrusion 31 is caught in the limiting stopper 52, and when the second stage that the barrel part 3 and the front barrel part 1 are far away from each other in the axial direction is realized, the catching protrusion 31 can be separated from the limiting stopper 52 and return to the original position, which should be a variety of implementations that can be reasonably derived by those skilled in the art according to the above description, and the following examples are specific structures.

As shown by the dotted line in fig. 8, when the barrel portion 3 is compressed relative to the locking member 5, the catching protrusion 31 moves along the first guide path 51a from the initial position to the end along the first guide slope 51b, and at this time, the locking member 5 rotates until the catching protrusion 31 is located at the end of the first guide slope 51b, and the barrel portion 3 is compressed relative to the locking member 5 to the maximum stroke for the first time. After the hand is loosened, the clamping piece protrusion 31 rebounds along the second guide slide way 51c, and under the action of the first limiting slope 52a, the clamping part 5 rotates again, so that the clamping piece protrusion 31 is clamped into the blocking clamping position 52b, and the pen point of the pen refill is stably exposed at a proper position. When the barrel portion 3 is compressed relative to the catching part 5 for the second time, the catching part 5 rotates to move the catching protrusion 31 along the second guide slope. The clamping part 5 rebounds after the hand is released, and the clamping part bulge 31 moves along the third guide slide way until the clamping part 5 rotates around under the action of the return guide slope; the card member protrusion 31 returns to the initial position, and the pen core 2 is in a hidden state. The force in the carry stage is acted by relative motion of the pen barrel part 1 and the pen barrel part 3 before being extruded by a single hand, and the force in the return stage is all completed by the elastic force of the spring 4.

The locking groove 16 is offset from the rotation-stopping straight groove 15 and the compression straight groove 17 in the circumferential direction. The locking groove 16 is connected to the rotation stopping straight groove 15 or the compression straight groove 17 through groove walls of the locking guide groove 15a, respectively, to form a rotational guide of the locking dog 33.
