Abstract

The utility model discloses an anti-break pen, which aims to provide an anti-break pen preventing a pen point from breaking when a pen is falling down. The anti-break pen comprises a cap (6), a penholder (1) and a spring (4). An inner connecting rod (2) which is fixedly connected to the penholder (1) is disposed in the penholder (1). The penholder (1) is provided with two symmetrical strip-shaped holes (5). The cap (5) is fixedly connected to two strip-shaped holes (5) through an outer connecting rod (3). The anti-break pen is advantageous in that the structure is simple and the producing is convenient; the protection effect to a pen is obvious and the practicality is strong.

Description

Antibreaking pen

Technical field

The utility model relates to a kind of pen, in particular, can prevent to break the Antibreaking pen of nib when it relates to a kind of dropping.

Background technology

At present, on the market the pen of a great variety, can up to the present can effectively not prevent the Antibreaking pen that nib is broken when also a kind of dropping occurring on the market.

Summary of the invention

The purpose of the utility model is the deficiency that overcomes existing product, and a kind of Antibreaking pen that can effectively prevent to break nib is provided.

The purpose of the utility model is achieved through following technical proposals:

The Antibreaking pen of the utility model comprises the cap for brush, penholder and spring etc., and the inside connecting rod that is fixedly connected with penholder is arranged in the described penholder, and the strip hole of two symmetries is arranged on the described penholder, and the described cap for brush is fixedly connected through outside connecting rod with strip hole.Described inside connecting rod, spring and outside connecting rod all are to be fixedly connected on the penholder, and the extension and contraction control outside connecting rod of described spring moves up and down in strip hole.

The beneficial effect of the utility model is: (1) is simple in structure, is easy to make; (2) obvious to the protective effect of pen, practical.

Description of drawings

Fig. 1 is the structural representation under the user mode of the utility model; The sketch map that Fig. 2 is the utility model under user mode not;

Among the figure: penholder 1, inside connecting rod 2, outside connecting rod 3, spring 4, strip hole 5, the cap for brush 6.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to describe.

In Fig. 1, Antibreaking pen mainly is made up of penholder 1 (having certain roughness), inside connecting rod 2, outside connecting rod 3, spring 4, inner strip hole 5, the cap for brush 6 of penholder.

In Fig. 2, the formation of Antibreaking pen is constant, but state changes.

Inside connecting rod 2 is a fixing integral body with penholder 1 in Fig. 1; Be fixed together with inside connecting rod 2 other end of (effect that inside connecting rod 2 mainly plays fixing spring 4) spring 4 of spring 4 is fixedly connected with outside connecting rod 3; Outside connecting rod 3 passes penholder 1 inner strip hole 5 and is fixedly connected with the cap for brush 6; Because spring 4 can freely stretch, so inside connecting rod 2 is movable with the cap for brush 6.Its movable scope is exactly the length of strip hole 5.When pen is in compressive state at user mode lower spring 4, and people have given the cap for brush 6 one pressure with hand when using pen, the elastic force of spring 4 that formed the frictional force balance between the cap for brush 6 and the penholder 1, and pen is use normally.

When pen does not use or during improper disengagings, the cap for brush 6 loses pressure, frictional force disappears, and spring 4 extend the drive outside connecting rod 3 and the cap for brush 6 naturally, and the cap for brush 6 reaches Fig. 2 state, nib is protected interior, thereby played the effect of shatter-resistant.

Claims

1. Antibreaking pen; Comprise the cap for brush (6), penholder (1) and spring (4) etc.; It is characterized in that; The inside connecting rod (2) that is fixedly connected with penholder (1) is arranged in the described penholder (1), the strip hole (5) of two symmetries is arranged on the described penholder (1), the described cap for brush (6) is fixedly connected through outside connecting rod (3) with strip hole (5).

2. according to right 1 described Antibreaking pen, it is characterized in that described inside connecting rod (2), spring (4) and outside connecting rod (3) all are to be fixedly connected on the penholder (1).

3. according to right 1 described Antibreaking pen, it is characterized in that the extension and contraction control outside connecting rod (3) of described spring (4) moves up and down in strip hole (5).
