Further, the basal surface of those teats has different shape or size.
Further, those teats are separated from each other.
Further, those teats are arranged symmetrically.
Further, those teats are: arrange symmetrically at the center according to the basal surface of this base portion, and with in the process of hardness test, this gauge head applies the teat of uniform pressure to this determinand evenly.
According to the utility model on the other hand, a kind of gauge head of hardness test meter is provided.Gauge head comprises base portion and most teats.Teat is arranged on the below of base portion.Teat is separated from each other and has different size or shape.In the process of tested for hardness, the basal surface of teat contacts with determinand.
Further, those teats are: arrange symmetrically at the center according to the basal surface of this base portion, and with in the process of hardness test, this gauge head applies the teat of uniform pressure to this determinand evenly.
Further, the basal surface of those teats has different shape or size.
According to the utility model again on the other hand, a kind of hardness test meter with above-mentioned a kind of gauge head is provided.
Compared with prior art, gauge head of the present utility model has a plurality of shapes or the different teat of size, therefore uses this gauge head to measure number of times and time that hardness can reduce measurement, and convenience also saves time.But the teat symmetry of gauge head ground is arranged, and in the process of hardness test, gauge head can apply uniform pressure evenly to determinand, and obtains measurement accurately by this.In addition, according to the condition of the base portion of gauge head, the position of the teat of gauge head can suitably be arranged, to obtain the gauge head of realistic requirement.
Can describe in detail and appended graphic being further understood by following utility model about advantage of the present utility model and spirit.

Embodiment
The gauge head of embodiment of the present utility model has a plurality of teats, and teat has different shapes or size, therefore can use a gauge head and carry out a hardness measurement step to obtain most measurements, can reduce measuring number of times and time, and improve the efficient that measures.
Fig. 2 A is the stereographic map of the gauge head of the utility model first embodiment.Fig. 2 B is the upward view of the gauge head shown in Fig. 2 A.Please refer to Fig. 2 A, gauge head 20A comprises base portion 40A and most teat 30A.Teat 30A is arranged on the below of the basal surface 41A of base portion 40A.Teat 30A becomes big from left to right gradually and is of different sizes.From the side, teat 30A has identical height.In addition, teat 30A is not limited to the column of the fixed diameter shown in Fig. 2 A, and the taper that also can narrow down gradually from top to bottom, or other shape.Please refer to Fig. 2 B, the basal surface 31A of teat 30A is of different sizes.The shape of the basal surface 31A of teat 30A is not limited to the circle shown in Fig. 2 B, and also can or have different shapes for other shape, for example circle, triangle or other polygon etc.
