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 rear part 3 of the penholder is compressed for the second time relative to the blocking part 5, namely, the blocking part 5 rotates to enable the clamping piece bulge 31 to move 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 realized by the relative motion action of the front part 1 of the penholder and the rear part 3 of the penholder which are extruded by one hand, and the force in the return stage is realized by the elastic force of the spring 4.
Further specifically, in terms of shape and structural expression, the limiting stopper 52 is composed of a first limiting member 521 and a second limiting member 522, the first limiting member 521 and the second limiting member 522 are both strip-shaped protrusions with two parallel sides, and one end of each of the first limiting member 521 and the second limiting member 522 is connected to form a 7-shaped blocking step, an acute angle is formed at the connection position of the first limiting member 521 and the second limiting member 522, and the acute angle accommodating area is the blocking position 52 b. The polygonal slot 51 is a polygonal groove formed by overlapping two parallelograms which have different sizes and are overlapped by the extension lines of two adjacent sides.
