Description

  The present invention relates to a kind of handwriting recognition expansion / contraction touch pen, and more particularly to a handwriting recognition touch pen of a PDA, a mobile phone or other related electronic products.

  In general, the pen structure used for a PDA or a mobile phone or the like generally employs a telescopic structure so that it can take up space and provide comfort in gripping. The one described in Patent Document 1 shown in FIG. 5 is a three-stage structure, and is composed of three tubular bodies of a first rod 90, a second rod 91, and a third rod 93. Among these, the nib 900 is fitted to the front end of the first rod 90, and the rear end is connected to the front end of the second rod 91. The rear end of the second rod 91 is connected to the front end of the third rod 92. When the pull head 93 is combined with the rear end of the third rod 92, the third rod 92 and the second rod 91 are moved back and forth. Then, the pen drawn out of the first rod 90 and stretched is formed. Among them, a pair of metal spring pieces 94 is provided between the first rod 90 and the second rod 91, and between the second rod 91 and the third rod 92, and the metal spring piece 94 is a half of the circumference. A cylindrical circular arc shape having a smaller circle is provided, and a convex portion 95 is provided at one end, and a set of positioning is provided at predetermined positions of the first rod 90 and the second rod 91 and the second rod 91 and the third rod 92. A hole 96 is provided, and the metal spring piece 94 is engaged with the positioning hole 96 by the convex portion 95 to prevent deviation. Further, since the cylindrical arcuate body itself has a certain elasticity, two mutually corresponding metal spring pieces 94 are joined to the end portions of the second rod 91 and the third rod 92 to form a locking part. Thus, the first rod 90, the second rod 91, and the third rod 92 are not escaped and decomposed when stretched.

The known structural design is incomplete and its drawbacks are as follows.
1. The main drawback is that there is a frictional sound when stretching or stretching, the feeling of operation is uncomfortable due to the mutual movement between the metal spring 94 and the tube, and sometimes there is noise, the quality is not good and the life is not long. .
2. The locking part of the structure end is not sealed and therefore the lubricant cannot be added to increase the texture.
3. Another drawback of known techniques is difficult and time consuming to assemble. Since the two metal spring pieces 94 are manually positioned and then inserted into the rod, misalignment is likely to occur, and the small protrusion 95 is not firmly engaged with the positioning hole 96.

  Further, FIG. 6 shows a touch pen described in Patent Document 2, which includes an outer barrel 101, an intermediate barrel 102, and an inner barrel 103. Both the outer barrel 101 and the middle barrel 102 are hollow tubular items, and the middle barrel 102 is housed inside the outer barrel 101 and slides inside the outer barrel 101, and the inner barrel 103 is a real core column. A first fitting portion 131 fitted into the outer barrel 101 and a second fitting portion 132 inserted into the middle barrel 102 are provided at the ends. The outer barrel 101, the middle barrel 102, and the inner barrel 103 are integrally fitted with a coaxial relationship, and when the touch pen is extended, the first fitting portion 131 of the inner barrel 103 corresponds to the outer barrel 101. The second fitting part 132 is fitted into the opening of the corresponding one end of the middle barrel 102. When the touch pen is retracted for storage, the inner barrel 103 is stored inside the middle barrel 102, and the middle barrel 102 is further stored in the outer barrel 101 together with the inner barrel 103.

  Patent Document 2 has two drawbacks in use. One of them is that when the two end fitting parts 131 and 132 of the inner barrel 103 are outside and the inside barrels 101 and 102 are fitted inside, the outer surfaces of the two fitting parts 131 and 132 are completely outside. Since the inner barrel 103 abuts against the inner wall surface of the middle barrels 101 and 102 and the inner barrel 103 has a real core structure, the expansion and contraction operation when using the touch pen is not smooth and is more severe. When the atmospheric pressure does not equilibrate quickly, the touch pen cannot be expanded or contracted. The other is that the inner barrel 103 has a real structure, so that the weight of the entire touch pen increases, and when the touch pen is in the extended use state, the inner barrel 103 is in the upper position of the pen, and the weight imbalance is reduced. Therefore, the touch pen of Patent Document 2 needs to be improved.
