Detailed description of the invention
A kind of specimen holder being applicable to sanding and polishing operation as depicted in figs. 1 and 2, comprise two pieces of square fixed heads 1 be arranged in parallel, square fixed head 1 while offer bar shaped chute 3, relative with bar shaped chute 3 while offer two screws 2 on square fixed head 1, the length of described bar shaped chute 3 is not less than the distance between described two screws 2, two pieces of described square fixed heads 1 are fixedly connected with the second screw rod 6 wearing screw 2 by the first screw rod 4 wearing bar shaped chute 3, described first screw rod 4 is two screw rods that can slide along bar shaped chute 3, described first screw rod 4 and described second screw rod 6 are provided with clamp nut 5.
In the present embodiment, adopt two first screw rods 4 that can slide along bar shaped chute 3 by sample laterally clamping, further, the distance between two the first screw rods 4 is adjustable, also can realize clamping multiple sample simultaneously; The present embodiment is by the displacement of the square fixed head 1 of adjustment two on the first screw rod 4 and the second screw rod 6, and it is fastening by clamp nut 5, to reach spacing between the square fixed head 1 of adjustment two thus by sample longitudinally clamping, so realize stable holding sample, reduce the Personal Risk of operating personnel, improve the operating efficiency of sanding and polishing sample.Further, the distance between two square fixed heads 1 is adjustable, also can realize the sample clamping difformity, size.
In the present embodiment, preferred square fixed head 1 is stainless steel, contributes to extending service life of the present utility model.
As shown in Figure 1, described bar shaped chute 3 medial surface is provided with the guiding screw thread with described first screw rod 4 threaded engagement.Arrange in bar shaped chute 3 and guide screw thread to be to guide the first screw rod 4 to slide in bar shaped chute 3, after the first screw rod 4 laterally clamps sample and adopts clamp nut 5 fixing, guide the setting of screw thread and clamp nut 5 can fastening first screw rod 4 further, make the clamping of the transverse direction of the first screw rod 4 pairs of samples more stable.
Further, the upper surface of square fixed head 1 described in the present embodiment and lower surface are provided with elastic cord breaker (not shown).The upper surface of square fixed head 1 and lower surface are provided with elastic cord breaker can make operating personnel's comfortable feel when hand-held fixture of the present utility model; In addition, two square fixed heads 1 also can be avoided to destroy sample when clamping sample.In the present embodiment, preferred elastic cord breaker is for having certain flexible soft polymer material layer.
As shown in Figure 1, described clamp nut 5 is wing nut.Because wing nut can ensure moment of torsion, adopt wing nut as securing member, the clamping of square fixed head 1 pair of sample can be made more stable.
Another kind of detailed description of the invention of the present utility model is: one end of the second screw rod 6 is fixed on a square fixed head in two square fixed heads 1, and the other end of the second screw rod 6 is provided with clamp nut 5 through after another the square fixed head in two square fixed heads 1.Design like this, not only cost of manufacture can be saved, and when clamping sample, only need the clamp nut 5 of adjustment second screw rod 6 other end, namely the distance between adjustable two square fixed heads 1, thus longitudinal fastening sample, simplify experimental procedure, decrease experimental period, reduce the labour intensity of staff.
