Technical Field

The invention relates to the technical field of medical auxiliary tools, in particular to a sheet-cutting sand bar handheld device.

Background

The sliced sand strip is mainly used for removing enamel (IPR) on the adjacent surface in the orthodontic process to provide clearance for orthodontics. At present, the slicing and grinding strip is mostly designed in a horizontal strip mode, and the two ends of the slicing and grinding strip are clamped by hands or needle holders, so that the slicing and grinding strip is inconvenient to use in a narrow oral cavity. The machine sheet cutting sand strip adopts the integrated design of the sand strip and the clamping device, the surface of the sand strip is very easy to wear, the whole replacement cost is high, and the disinfection is not facilitated. The invention provides a sand strip clamping device which is used for clamping a sand strip designed by a transverse strip, is convenient to replace and sterilize and can be used for controlling the glaze removal effect accurately by hand.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a sheet cutting sand strip handheld device.

In order to solve the technical problem, the technical scheme provided by the invention is that the sheet-cutting sand strip hand-held device comprises: comprises a connecting rod and clamping columns symmetrically arranged at two ends of the connecting rod; one end of each clamping column is fixedly connected with the connecting rod, the end, far away from the connecting rod, of each clamping column is horn-shaped, an open slot is formed in the end, far away from the connecting rod, of each clamping column, the extending direction of each open slot is the same as the extending direction of the connecting rod, and planes of the open slots on the two clamping columns form a certain included angle; the adjusting pipe is sleeved on the outer side of the clamping column, a spring is arranged in the adjusting pipe, and the adjusting pipe can slide along the extending direction of the clamping column.

As the improvement, the extending direction who presss from both sides tight post, regulating tube, spring is the same, the opening diameter that is close to tight post loudspeaker type end of regulating tube is less than the maximum diameter who presss from both sides tight post loudspeaker type end, and works as when the opening that is close to tight post loudspeaker type end of regulating tube and the circumferencial face laminating that presss from both sides tight post loudspeaker type end, press from both sides the relative regulating tube of tight post and stretch out, just press from both sides the width that the relative regulating tube of tight post stretched out length more than or equal to sliced sand strip.

As an improvement, the horn-shaped end of the spring close to the clamping column is fixedly connected with the adjusting pipe, the other end of the spring is fixedly connected with a support ring, and the support ring is fixedly connected with the clamping column.

As an improvement, a first holding rod is fixedly connected between the two adjusting pipes and is arranged at the end, close to the connecting rod, of the adjusting pipe.

As an improvement, the ends, close to the connecting rods, of the two adjusting tubes are fixedly connected with holding tubes, the holding tubes are communicated with the adjusting tubes, the holding tubes are sleeved on the outer sides of the connecting rods, and in an initial state, due to the elastic action of the springs, the connecting rods are in extrusion fit with the inner walls, far away from the supporting ring side, of the holding tubes.

As an improvement, the middle part of the holding tube, which is far away from the side of the supporting ring, is provided with a through hole, the middle part of the connecting rod, which is far away from the side of the supporting ring, is fixedly connected with a sliding rod matched with the through hole, and the end, which is far away from the connecting rod, of the sliding rod is fixedly connected with a second holding rod.

Compared with the prior art, the invention has the advantages that: the invention is very convenient when loading and unloading the sheet-cutting abrasive strip, and the sheet-cutting abrasive strip is reliably fixed, the stress of the fixing parts at the two ends is uniform, the coarsening effect on teeth is better, the structure is simple, the use is convenient, and the practicability is very good.
