On the basis of the technical scheme, the utility model can be further improved as follows:

further: the convex block is in a cone frustum shape with a downward cone tip.

Further: and a first arc-shaped chamfer is arranged at the joint of the lug and the handle body. The beneficial effect of this step: stress concentration is reduced by chamfering one.

Further: the first concave part is arc-shaped. The beneficial effect of this step: so that the shape of the first concave part is more matched with that of the finger holding part.

Further: and an anti-skid bulge is arranged in the first concave part. The beneficial effect of this step: the friction force during holding is increased by the anti-skid protrusions.

Further: the antiskid protrusions are located at one end, far away from the protruding blocks, of the first concave portion.

Further: and a second concave part is arranged in the middle of at least one of the left side surface and the right side surface of the handle body. The beneficial effect of this step: the handle body is convenient to manually hold through the second concave part, and the holding stability is improved.

Further: the second concave part is arc-shaped. The beneficial effect of this step: the shape of the second concave part is more matched with that of the part where the fingers are held.

Further: the upper end of the handle body is provided with a boss for connecting the needle body.

Compared with the prior art, the utility model has the beneficial effects that: through setting up the lug, be convenient for mark human skin to the handle body is held by the manual work of being convenient for of depressed part one and depressed part two that set up, travelling comfort and stability when increasing to hold.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

As shown in fig. 1 and 3, a small needle knife handle includes: handle body 1, handle body 1 lower extreme is provided with lug 2, and lug 2 is used for pricking the position at skin mark, and handle body 1 upper end is provided with boss 3 that is used for connecting the needle body, extrudees at human skin through this boss 3 and forms the mark, the operation of being convenient for prick the needle.

As shown in fig. 1, the bump 2 is in the shape of a truncated cone with a downward conical tip, a circular arc-shaped chamfer 4 is arranged at the boundary between the bump 2 and the handle body 1, and the stress concentration is reduced by the circular arc-shaped chamfer 4, so that the strength of the handle body 1 is increased.

Wherein, as shown in fig. 2, the middle part of preceding terminal surface and the rear end face of the handle body 1 all is provided with depressed part one 5, depressed part one 5 is arc, thereby make the handle body 1 from last to form the structure that the thick first reduces gradually then increases gradually of board, set up the aim at of depressed part, because when the handle body 1 is handed to the manual work, generally adopt thumb and forefinger to grip in depressed part one 5, and the place that the finger was gripped has the radian, set up depressed part one 5 into arc, thereby be convenient for the manual work and grip this handle body 1, in order to improve the travelling comfort and the stability of gripping.
