Valve holder

A valve holder including:

• a base including a through hole extending in a first direction;
• two arm members symmetrically extending from opposing sides of the base, each of the two arm members including a first arm, a second arm and a third arm, an end of the first arm and an end of the second arm being separate in the first direction and connected to the base, another end of the first arm and another end of the second arm extending in the first direction and being integrally merged with each other and connected to the third arm, the base, the first arm and the second arm forming a room;
• and
• two clamping members, each of the two clamping members including a main body connected to the third arm and a plurality of projections, the main bodies of the two clamping members being arranged in interval in a direction perpendicular to the first direction and defining a clamping space configured for receiving a portion of a valve, the plurality of projections being disposed on the clamping member and projecting to be within the clamping space for engaging with the valve;
• wherein the main body has two of the plurality of projections, one of the two of the plurality of projections is flash with an end surface of the main body remote the base to form a first guide surface, and the first guide surface is inclined to the first direction;
• the first guide surfaces of the two clamping members extend taperedly toward the base in the first direction, and the first guide surfaces of the two clamping members define an opening.
