ある。[Detailed description of the invention] The present invention is a chuck device for a sharp pencil, which comprises a chuck body capable of holding a lead, a chuck actuating body cooperating with the chuck body, and a ball interposed between the chuck body and the chuck actuating body. It is related to.

満足せる機能をチヤツク装置に求めるためには加
工が複雑になる等して、コストが非常に高くなる
といつた問題がある。 Conventionally, in this type of chuck device, when the core moves forward, this forward movement is not hindered.
On the other hand, when the core retreats, it strongly prevents this retreat through a wedge action, which is a unique function not found in ordinary collect chucks. However, in order to satisfy this function, positioning accuracy such as the slot position of the chuck body and the ball position is required.
In order to obtain satisfactory functions from the chuck device, processing becomes complicated, resulting in a very high cost.
本考案は上述せる問題に鑑みなされたもので、
チヤツク装置に工夫を施こすことにより機能を満

る。 1 and 2 show a first embodiment of the present invention, reference numeral 1 is a chuck body, and this chuck body 1 consists of two pieces of core having a tapered ball receiving surface 2 on the front outer surface. The rear portions of the clamping pieces 3, 3 are connected by a connecting body 4. 5 is the chuck body 1
The chuck operating body 5 is equipped with a ball guide surface 6 having a substantially circular arc shape in longitudinal section on the inner surface of the front portion. Reference numeral 7 denotes balls (two balls in the figure) located between the ball receiving surface 2 and the ball guide surface 6 described above, and these balls 7 are attached to a cylindrical retainer 8 fixed to the connecting body 4 described above. hole 9
It is placed in such a way that its position is regulated.
