Abstract

The utility model provides a pen which comprises a penholder and a pen cap, wherein a pen head thread is formed on the penholder in positions near a pen head; a pen tail thread is formed on a pen tail of the penholder; the pen head thread and the pen tail thread are external threads with same size; an internal thread matched with the pen head thread and the pen tail thread is formed on the pen cap; and metal compression rings are arranged at the two ends of the pen tail thread. The pen is characterized by simple and firm structure and convenient use.

Description

Pen

Technical field

The utility model relates to a kind of pen.

Background technology

When the pen of the existing band cap for brush uses the cap for brush being taken off the back directly throws away the cap for brush aside or cooperates the secure fit that realizes between the cap for brush and the penholder by the cap for brush with the clamping of penholder afterbody, directly throw away and then lose the cap for brush aside easily, and cooperate the form that the cap for brush is fixed on the penholder also to have defective by clamping, owing to each use pen all to need the cap for brush taken off from pen head part to snap fit onto the penholder afterbody, often use just to make the cap for brush cooperate wear out failure easily, and the unstable defective of cooperation itself is also deposited in this clamping cooperation with clamping between the penholder.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, sound construction, pen easy to use.

In order to solve the problems of the technologies described above, technical solution of the present utility model is such: pen comprises the penholder and the cap for brush, wherein penholder is provided with written screw thread near written position, a penholder tail position is provided with a tail screw thread, the nib screw thread is the external screw thread of identical size with a tail screw thread, the described cap for brush is provided with the internal thread with a written screw thread and a tail threads engaged, and described tail screw thread two ends are provided with the metal pressure ring.

Because in the above-mentioned technical solution, penholder is provided with written screw thread near written position, a penholder tail position is provided with a tail screw thread, the cap for brush is provided with the internal thread with a written screw thread and a tail threads engaged, during use the cap for brush is screwed out from written screw thread, again the cap for brush is screwed in a tail screw thread and make the cap for brush extremely be securely fixed in the penholder afterbody, because penholder is generally working of plastics, therefore a tail screw thread two ends is provided with the metal pressure ring and can makes a structure at tail screw thread place more firm.

Description of drawings

Fig. 1 be the utility model provide the pen the overall structure schematic diagram.

The specific embodiment

The invention will be further described below in conjunction with the drawings and specific embodiments.

Wherein: 1, penholder; 2, the cap for brush; 3, written screw thread; 4, a tail screw thread; 5, internal thread; 6, metal pressure ring; 7, transition projection.

As shown in Figure 1, pen provided by the utility model, comprise penholder 1, the cap for brush 2, penholder 1 is provided with written screw thread 3 near written position, 1 tail position of penholder is provided with a tail screw thread 4, and written screw thread 3 is the external screw thread of identical size with a tail screw thread 4, and the described cap for brush 2 is provided with and a written screw thread 3 and an internal thread that tail screw thread 4 matches 5, described tail screw thread 4 two ends are provided with metal pressure ring 6, and that this pen has is simple in structure, sound construction, characteristics easy to use.

As shown in Figure 1; described penholder 1 tail end is provided with transition projection 7; transition projection 7 is set further plays reinforcement effect a tail screw thread 4; can also when not cooperating with a tail screw thread 4, the cap for brush 2 avoid a tail screw thread 4 to be directly exposed to penholder 1 afterbody; penholder 1 afterbody lands and directly damages a tail screw thread 4 when having avoided pen to drop, and a protection tail screw thread 4 is not damaged and makes its Acceptable life longer very effectively.
