Abstract: An infusion flow regulator includes: a main body having an inlet through which fluid is introduced and an outlet through which the fluid is discharged; and a rotary dial rotatably coupled to the main body, with a sealing member interposed therebetween, so as to regulate a flow rate of the fluid, in which the rotary dial includes a regulating flow path having a shape of a recessed groove in cross section with a first width and a first height, and the regulating flow path includes a first region in which the first width is constant and the first height is decreased, and a second region in which both the first width and the first height are decreased. By the aforementioned configuration, the infusion flow regulator for the fluid can accurately regulate the flow rate even in a region where the flow rate of the fluid is very small.

Abstract: Disclosed is a golf tee including a main body having an upper seat on which a golf ball is supported; an insertion pin having a lower pointed part; and a connection pin connecting the insertion pin and the main body, the connection pin including an upper integral-type head part and a body part extending from the head part and having a lower screw section on a lower end thereof and around which a spring is integrally fitted, the insertion pin having an elongated screw hole extending from an upper central portion thereof such that the screw part of the connection pin is screwed therethrough.

Abstract: A golf tee for separating the upper body and the lower pin body at the impact moment. The tee has increased re usability. The tee has two springs inside. One spring is inside of an upper head body made of a transparent and flexible outer layer having a golf ball placement at the top. The other spring is embedded in a plastic pin. Those springs are connected by a flexible polymer string connector, which is inserted inside of the springs. Both ends of the flexible plastic string connector has a diameter larger than that of the springs to hold the upper end of the spring in the upper body and the lower end of the other spring in the pin. The springs, inside of the upper head body and inside of the pin, retract at the impact moment.

Abstract: The present invention provides a golf tee wherein a body (1) and a stick pin (2) for sticking to the ground are separated and formed to be connected with the clevis pin (8), a spring (7) is provided in the inner portion of the body (1), the body (1) is, upon striking of golf ball, bent in the progress direction of the golf ball, thereby a frictional resistance to the golf ball and golf tee is minimized and a light striking can be made, and further a ratio length of the golf ball can be further extended. Further, the bent body can be automatically restored in an original state and conveniently re-used.

Abstract: The present invention provides a holder of small pieces which consists of a coil spring and wherein its inlet narrows step by step to form a concave portion connected by a certain section and further form a convex portion which is outwardly projected. The holder of the present invention can simply wear and carry short pieces such as ball pen or golf tee and thus, more conveniently carry, store and use various kinds of small pieces.
