Abstract
A rotary cassette pencil relates to a propelling pencil which can load cassette large-diameter pencil-lead. A shell of a pencil holder is integrated with a pencil head, and the tail end of the pencil holder uses internal thread while the inside of the pencil head uses staircase structure. An inside hollow pencil lead is integrated with a claw, a tail end of the hollow pencil lead uses external thread and the claw is an external bevel. The pen head is matched with the claw to clamp the pencil lead, while the tail end thread is matched together to keep a state of clamping, thus loading the pencil lead with thick diameter.
Description
Affiliated technical field
The utility model relates to a kind of propelling pencil of the particle size pencil-lead that can be installed.
Background technology
At present, known propelling pencil external structure is made up of penholder shell, nib; Internal structure is formed by connecting by hollow pen core, metal spring, cutting ferrule, claw.Utilize spring pressure to promote cutting ferrule and make claw chucking pencil-lead.This propelling pencil particle size pencil-lead that similar Wood pencil uses that can not be installed, the scope of application is limited.
Summary of the invention
In order to solve can not the be installed problem of particle size pencil-lead of existing propelling pencil, the utility model provides a kind of propelling pencil, this pencil particle size pencil-lead that can be installed.
The technical scheme that its technical problem that solves the utility model adopts is: outside penholder shell and nib are closed as a whole, and tail end uses internal thread, and hierarchic structure is used in the inside of pen head part; Inner hollow pen core and claw close as a whole, and tail end uses external screw thread, and claw partly is outer inclined-plane.Behind hollow pen core screw-in penholder, the outer inclined-plane of claw is subjected to the extruding of written ladder projection to make claw chucking pencil-lead, and the tail end screw thread cooperatively interacts with the maintenance gripping orientation, thereby reaches the purpose of the particle size pencil-lead that is installed.
The beneficial effects of the utility model are, the particle size pencil-lead that can be installed is simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the installation profile of the utility model embodiment.
Fig. 2 is the penholder shell section figure of the utility model embodiment.
Fig. 3 is the hollow pen core profile of the utility model embodiment.
1. penholder shells among the figure, 2. tail end internal thread, 3. pen head part, 4. hollow pen core, 5. tail end external screw thread, 6. dop part.
The specific embodiment
In the embodiment shown in fig. 1, hollow pen core (4) rotates in the penholder shell (1), tail end external screw thread (5) cooperates with tail end internal thread (2), and the inclined-plane of dop part (6) is subjected to the extruding of pen head part (3) projection that dop partly is out of shape and produces pressure pencil-lead is tightened.For guaranteeing that the dop part can obtain enough and lasting pressure, tail end external screw thread and tail end internal thread should closely cooperate, and the dop operative tip does not contact with the pen head part inwall.
Claims (1)
1. propelling pencil, penholder shell, nib, hollow pen core, dop connect and cooperate, it is characterized in that: the penholder shell is threaded with tail end with the hollow pen core, and the internal protrusion of penholder shell pen head part cooperates chucking with the outer inclined-plane of hollow pen core dop part.
