Specific embodiment

Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.

As depicted in figs. 1 and 2, a kind of irregular semicircle bone concave boost motor, it is characterised in that: including pedestal 1 and caltrop 4；

The front end face 11 of the pedestal 1 is equipped with the first spherical surface 2 to concave, and the surface scarfing of first spherical surface 2 is multiple The caltrop 4；

The rear end face 12 of the pedestal 1 is equipped with the second spherical surface 3 to concave, and the surface scarfing of second spherical surface 3 is multiple The caltrop 4；

What first spherical surface 2 and second spherical surface 3 were respectively formed on the pedestal 1 is used to accommodate in semicircle bone Concave space.

When semicircle bone is placed on first spherical surface 2 and second spherical surface 3, the caltrop 4 pierces semicircle bone table The tissue in face makes semicircle bone be not likely to produce loosening in cutting process or fall off, to obtain good to fixed semicircle bone It is sliced sample.

It further explains, as shown in figure 3, the caltrop 4 includes that thorn tapering 41 and embedded division 42, the embedded division 42 are set There are multiple annular grooves 421, the embedded division 42 is respectively embedded into first spherical surface 2 and second spherical surface 3, the thorn tapering 41 The surface of first spherical surface 2 and second spherical surface 3 is protruded from respectively, and the central axis of the caltrop 4 is across described The centre of sphere of first spherical surface 2 or the second spherical surface 3.

The thorn tapering 41 is cone, can effectively pierce semicircle bone surface tissue, and the embedded division 42 is equipped with multiple Annular groove 421, this structure keep the connection of the caltrop 4 and the pedestal 1 stronger, and the caltrop 4 is not easy to be pulled out.

It further explains, as depicted in figs. 1 and 2, multiple caltrops 4 are respectively in first spherical surface 2 and described the It forms a circle on two spherical surfaces 3, and the thorn tapering 41 of the caltrop 4 does not protrude from the front end face 11 or rear end face 12.Institute It states the first spherical surface 2 and second spherical surface 3 is equipped with a circle caltrop 4, semicircle bone can be pierced in different directions, It is more firm when cutting.

It further explains, as depicted in figs. 1 and 2, the radius of turn R of first spherical surface 2₁Less than second spherical surface 3 radius of turn R₂, opening size W of first spherical surface 2 at the front end face 11₁Less than second spherical surface 3 in described Opening size W at rear end face 12₂.The size dimension of first spherical surface 2 and the second spherical surface 3 is not identical, can meet different rulers The clamping of very little semicircle bone.

It further explains, opening size W of first spherical surface 2 at the front end face 11₁Between 50-60mm, Opening size W of second spherical surface 3 at the rear end face 12₂Between 65-75mm；First spherical surface 2 is before described Hollow depth at end face 11 is between 13-20mm, and hollow depth of second spherical surface 3 at the rear end face 12 is in 13- Between 20mm.The diameter of the semicircle bone of required slice is between 50-70mm, the ruler of first spherical surface 2 and second spherical surface 3 Very little range can meet the slice demand of this kind of semicircle bone.

It further explains, as depicted in figs. 1 and 2, the middle part of first spherical surface 2 and second spherical surface 3 is set respectively Fluted 5.The groove 5 can accommodate some irregular semicircle bones with projection.

It further explains, as shown in Fig. 2, the rear end face 12 is equipped with notch 31.The notch 31 is convenient for described in difference First spherical surface 2 and second spherical surface 3.

It further explains, the upper surface 13 of the pedestal 1 and the junction of two sides 14 are equipped with the chamfering 6 of transition.Institute Stating chamfering 6 facilitates operator more comfortable when holding the irregular semicircle bone concave boost motor of the electric saw class.

It further explains, is respectively equipped with grip part 7 on the two sides 14 of the pedestal 1.The grip part 7 is vertical Ripple glaze facilitates operator preferably to hold the irregular semicircle bone concave boost motor of the electric saw class, pushes the electric saw class not Hand is not easy to skid when regular semicircle bone concave boost motor is cut.

It further explains, the material of the pedestal 1 is plastics, and the material of the caltrop 4 is stainless steel.Plastic material Density is small, light weight, it is more flexible in cutting to make the irregular semicircle bone concave boost motor, and plastic material is easier to realize Insertion connection is carried out with the caltrop 4.Semicircle bone surface often has water and other liquid, resistance to using the caltrop 4 of stainless steel making Corrosive nature is good.

Furthermore the print of different-thickness in order to obtain, the irregular semicircle bone concave boost motor usually with a baffle It is used cooperatively, the irregular semicircle bone concave boost motor pierces the periphery of semicircle bone, and the baffle withstands semicircle bone Half-plane pushes the irregular semicircle bone concave boost motor to saw blade according to the position of the thickness controllable register of required print It is mobile to carry out cutting sampling.

Technical principle of the utility model has been described above with reference to specific embodiments.These descriptions are intended merely to explain this reality With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein, Those skilled in the art, which does not need to pay for creative labor, can associate with other specific implementation modes of this utility model, These modes are fallen within the protection scope of the utility model.
