The first polygonal clamping groove 51, the limiting stopper 52 and the clamping member protrusion 31 have the following structure and specific embodiments:
the polygonal clamping groove 51 is positioned on the outer side wall of the middle part of the clamping part 5, and the limiting stopper 52 is positioned in the middle area of the polygonal clamping groove 51, so that the clamping piece protrusion 31 is accommodated in the guiding groove structure between the polygonal inner wall of the polygonal clamping groove 51 and the outer wall of the limiting stopper 52.
The guide groove structure comprises a first guide slide way 51a, a first guide slope 51b, a second guide slide way 51c, a second guide slope 51d, a third guide slide way 51e and a return guide slope 51f for the movement of the clamping piece protrusion 31; the first guide slide way 51a, the first guide slope 51b, the second guide slide way 51c, the second guide slope 51d, the third guide slide way 51e and the return guide slope 51f are connected in sequence in the first position, and the tail end of the return guide slope 51f is connected with the first guide slide way 51 a.
The limit stopper 52 includes a first limit slope 52a corresponding to the second guide slide 51c, and a blocking stopper 52b for accommodating the stopper protrusion 31 and exposing the pen tip of the pen; the blocking detent 52b axially corresponds to the middle of the second guide ramp 51 d.
As shown by the broken line in fig. 8, when the second barrel 3 is compressed relative to the stopper 5, the stopper protrusion 31 moves from the initial position along the first guide rail 51a until reaching the bottom along the first guide slope 51b, at this time, the stopper 5 rotates until the stopper protrusion 31 is located at the end of the first guide slope 51b, and the second barrel 3 is compressed to the maximum stroke for the first time relative to the stopper 5. After the hand is loosened, the clamping piece protrusion 31 is rebounded along the second guiding 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 refill nib is stably exposed at a proper position. When the second barrel 3 is compressed for the second time with respect to the click member 5, that is, the click member 5 rotates so that the click protrusion 31 moves along the second guide slope. After the hand is loosened, the clamping piece protrusion 31 moves along the third guiding slide way until the clamping part 5 rotates under the action of the return guiding slope; the clamp protrusion 31 returns to the initial position, and the pen refill 2 is in a hidden state. The force in the carry stage is acted by extruding the first pen holder barrel part 1 and the second pen holder barrel part 3 by one hand to perform relative movement, and the force in the return stage is acted by the elasticity of the spring 4.
Further specifically, in terms of shape and structural expression, the limiting stopper 52 is composed of a first limiting stopper 521 and a second limiting stopper 522, the first limiting stopper 521 and the second limiting stopper 522 are strip-shaped protrusions with two parallel sides, one end of each of the first limiting stopper 521 and the second limiting stopper 522 is connected to form a blocking step similar to a shape of a 7, and an acute angle is formed at the connection position of the first limiting stopper 521 and the second limiting stopper 522, and the acute angle accommodating area is the blocking clamping position 52b. The polygonal clamping groove 51 is a polygonal groove formed by overlapping two parallelograms which are different in size and respectively coincide with the extension lines of two adjacent sides.
A locking groove is provided on the rear portion of the first barrel 1, and a locking clip 33 is provided on the inner wall of the second barrel 3 corresponding to the locking groove. The locking grooves include an insertion guide groove 14, a rotation-stopping straight groove 15, a locking guide groove 15a, a locking card groove 16, and a compression straight groove 17. The guiding groove 14, the rotation stopping straight groove 15, the locking guiding groove and the compression straight groove 17 are sequentially communicated from the rear part to the front part of the first pen holder barrel part 1; the locking detent 16 is offset in the circumferential direction from the rotation-stopping straight groove 15 and the compression straight groove 17; the locking groove 16 is connected to the rotation stopping straight groove 15 or the compression straight groove 17 through the groove wall of the locking guide groove 15a, respectively, so as to form a locking clamp 33 rotation guide.
Further, the loading guide groove 14 is horn-shaped with a large rear part and a small front part, the front end of the loading guide groove 14 is communicated with the rotation stopping straight groove 15, and the front end of the rotation stopping straight groove 15 is communicated with the locking guide groove 15a; the lock guide groove 15a is formed by a first guide inclined wall 150 connecting the rotation-stopping straight groove 15 and the lock catch groove 16, and a second guide inclined wall 151 connecting the lock groove 16 and the rear end of the compression straight groove 17.
More specifically, each set of locking grooves includes one fitting guide groove 14, one rotation-stopping straight groove 15, two locking guide grooves 15a, two locking card grooves 16, and one compression straight groove 17; the two locking grooves are offset and located on both sides of the rotation stopping straight groove 15 and the compression straight groove 17, and a locking guide groove 15a and a locking groove 16 are distributed on each side.
When the clip protrusion 31 is separated from the limit stop 52 and the second barrel 3 and the first barrel 1 are in the second stage of axial separation, i.e. the cartridge 2 is in a hidden state, the locking clip 33 is just located in the rotation stopping straight groove 15.
The purpose of the locking groove is to prevent the pen core 2 from being extruded by external force and exposed when the pen core 2 is in a hidden state, so that the pen core 2 is prevented from being extruded in the schoolbag and the inner wall of the briefcase from being scratched or scratched. Specifically, it is configured such that the user slightly presses the first barrel portion 1 so that the locking clip 33 leaves the rotation-stopping straight groove 15 and enters the locking guide groove 15a. In the re-locking guide groove 15a, the locking clip 33 is guided into the locking clip groove 16 by the first guide inclined wall 150 or the second guide inclined wall 151, regardless of the rotation operation. The locking clamping groove 16 is in a clamping state after entering, no rotation force is applied, and the locking clamping groove is generally not only pulled out, so that the telescopic length between the second pen holder barrel 3 and the first pen holder barrel 1 is mechanically and axially locked, the uncertain state of elasticity of the spring 4 is overcome, only the structure is changed, the manual operation is simple, the cost of parts and materials is not increased, and the locking clamping groove has a deliberate effect.
