The holder portion 14b returns to the original state in which the pen 3 is clamped and fixed again. The above operation is repeated by pressing the holder portions 14a and 14b against each other.

[Problems to be Solved by the Invention] However, in the above-mentioned holder part, when the pen is passed from one holder part to the other holder part, a difference in frictional force between the claw part and the pen causes the pen part to move. There is a problem that the delivery state is different and the nipping position of the pen shifts or the pen falls.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a pen holder capable of reliably delivering a writing instrument between facing pen holders.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a movable claw whose rear side is rotatably supported by a shaft body in a state of facing a fixed claw extending forward. A pen holder which is provided with the spring body and presses and biases the front end side of the movable claw to the front end side of the fixed claw, and uses the elasticity of the spring body to clamp and fix the writing instrument with the both claws. In the vicinity of the shaft body on the inner side surface of the movable claw, a pressing piece extending toward the fixed claw is provided so as to project, and when the both claws hold and fix the writing tool, the tip end of the pressing piece is a writing tool. When the movable claw is rotated so that the front end side of the movable claw moves away from the fixed claw while retracting along the surface, the tip end of the pressing piece moves forward and pushes out the writing instrument forward. Take composition.

[Effect] That is, in the pen holder according to the present invention, the front end side of the rotatable movable claw disposed to face the fixed claw is urged by the spring body toward the fixed claw, and When a pressing piece is provided on the rear side of the side surface and the movable claw is rotated to move the front end side away from the fixed claw, the tip of the pressing piece moves from the rear to the front. Therefore, the two pen holders are arranged in a relative state, the writing instrument is clamped and fixed to one of the pen holders, and in this state, the front side of the one pen holder is pressed against the front side of the other pen holder,
Slide the two claws of the other pen holder between the inner measuring surface of the two claws of the one pen holder and the outer peripheral surface of the writing instrument to push the front end sides of the two claws of the one pen holder apart from each other. The pressing piece moves toward the front and pushes out the writing instrument to the other pen holder side. As a result, the writing instrument can be reliably delivered from one pen holder to the other pen holder. Further, the handing of the writing instrument from the other pen holder to the one pen holder is surely performed in the same manner.

Next, this invention will be described in detail based on embodiments.
