Optionally, the dental block booster 241 includes a resilient plate 2411. The elastic pushing force provided by the elastic plate 2411 is greater than the friction force between the tooth block and the jaw plate, so that the tooth block can be pushed. A circle of protective sleeve can be arranged around the elastic plate 2411, so that abrasion caused by contact and collision of the elastic plate 2411 and the tooth block in the tooth block boosting process is avoided, the service life of the elastic plate 2411 can be prolonged, and the cost is reduced. The material of the elastic plate 2411 may be spring steel or other materials, which is not limited herein. Fig. 5 is a schematic view of the booster assembly of the hydraulic clamp block remover of fig. 4. Alternatively, the number of the elastic plates 2411 is 2. The two elastic plates 2411 are parallel to form a notch capable of avoiding the telescopic pin, the two elastic plates 2411 can respectively prop against the edge of the tooth block separated by the notch, so that the elastic plates 2411 are in closer contact with the tooth block, the two elastic plates 2411 can also have the same shape as the radian of the tooth block, so that the tooth block can be better contacted with the tooth block, and the tooth block can be pushed more conveniently. When the dental block booster 241 is used, the dental block can be extruded through the elastic plate 2411, so that the elastic plate is elastically deformed under the action of pressure, meanwhile, the telescopic pin is pressed down through the ejector rod 23, when the end face of the telescopic pin is flush with the surface of the jaw plate, the dental block loses the constraint of the telescopic pin and can be rapidly pressed on the telescopic pin under the action of the elastic force released by the elastic plate 2411, at the moment, the ejector rod 23 can be controlled to stop pressing the telescopic pin, and the dental block is pushed out of the jaw plate through the dental block booster 241. The elastic force of the elastic plate 2411 makes the operator not need to deliberately find the time for withdrawing the ejector rod in the operation process, and the whole operation process is simpler and more convenient.
As shown in fig. 3. The other end 231 of the ejector rod 23 is tapered. The other end 231 of the ejector rod 23 is used for pressing down the telescopic pins, the diameters of the telescopic pins used on jaw plates and tooth blocks of different types are also different, the conical ejector rod 23 can cope with the telescopic pins of different diameters, and the ejector rod 23 does not need to be replaced frequently when the tooth blocks of different types are dismounted for a plurality of times. After the conical end presses down the telescopic pin, a certain space exists on the end face of the telescopic pin, and after the boosting assembly 24 pushes the tooth block, the tooth block can be pressed onto the end face of part of the telescopic pin, and then the ejector rod 23 is removed. Compared with the prior art, the embodiment of the invention does not need to grasp the opportunity to draw out the ejector rod 23 while pushing the tooth blocks during operation, and the operation is more convenient.
Optionally, the ejector rod 23 is screwed with the bracket 21. Screw holes can be formed in the support 21, the ejector rod 23 is in threaded connection with the support, disassembly and assembly are convenient, and the threaded connection is convenient for fixing the ejector rod 23 during operation. And the length of the jack 23 from the bracket to the other end 231 can be adjusted by rotating the jack 23.
In addition, the dental block suction end 221 of the magnetic assembly 22 may be a magnet. Wherein the dental block suction end 221 may be a permanent magnet, such as a neodymium iron boron strong magnet. The permanent magnet has the advantages of low cost, large magnetic energy storage, stable magnetic force and the like. The magnetic assembly 22 may also include a cartridge compartment into which the magnets are placed, and a flexible layer may be provided on the inner wall of the cartridge compartment to prevent the magnets from wearing away from the cartridge compartment. One surface of the box cabin, which is contacted with the tooth block, can be set to be an arc surface, and the arc tooth block is not easy to fall off after being adsorbed. The dental block suction end 221 can select a magnet which can suck dental blocks of common size even though the magnetic suction force penetrates through the box cabin. For example, the weight of a typical dental block is typically 50 grams to 200 grams, so that a magnet with a magnetic attraction of 9.8 newtons can be selectively passed through the capsule.
