Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
The present invention discloses a kind of block head, referring to Fig. 1 to Fig. 3, comprising: knob 1, positioning sleeve 2 and positioning ball 3, wherein
Positioning sleeve 2 has hollow space, and what knob 1 sealed is set in hollow space, and is threadedly engaged with positioning sleeve 2；
The direction that knob 1 protrudes into hollow space is first direction, and the top of knob 1 is centrum section 14, centrum section 14 in a first direction,
Diameter is gradually reduced；Positioning sleeve 2 has at least one radial through-hole 21, and perforation to hollow space positions ball 3 and is arranged in through-hole 21
Place, and after knob 1 protrudes into hollow space, the outer wall of institute's centrum section 14 supports positioning ball 3；Gasket is provided with outside positioning sleeve 2.
In use, positioning sleeve 2 protrudes into opening port, which can refer to any required mouth sealed.By turning rotation
Button 1, is gradually protruded into first direction, and the outer wall driving positioning ball 3 of centrum section 14 is moved to outside through-hole 21, and it is solid to stretch out through-hole 21
It is scheduled on the inner wall of opening port.In general, in a preferred embodiment, the smaller diameter with positioning ball 3 of the diameter of through-hole 21 is protected
The part of card positioning ball 3 can expose, and be connected in opening port.
Knob 1 is divided into a first direction: rotation section 11, linkage section 12, trench segment 13 and centrum section 14；Linkage section 12
