montant 32's lower extreme outer walls, and two third buffer spring 34's lower extreme respectively with the bottom wall body fixed connection of two montant fixed slot 31 inner chambers, third buffer spring 34's top fixedly connected with second buffer block 33, third buffer spring 34 and second buffer block 33 through setting up can play the effect of buffer protection to the first lifter 12 of the end of will rising, the quantity of second buffer block 33 is two, two second buffer block 33 are fixed connection respectively in two third buffer spring 34's top, and the middle part cover of two second buffer blocks 33 is established at two montant 32's outer wall.

It should be noted that, the invention is an operation guide plate for preparing an alveolar socket for autologous tooth transplantation, when in use, the operation guide plate body 15 is fixed on teeth of a patient, two elastic lantern rings 1 are hung on ears of the patient, then an ejector block 9 at the upper end is contacted with an upper jaw of the patient, an ejector block 9 at the lower end is contacted with a lower jaw, then a twisting block 13 rotates a rotating rod 40, the rotating rod 40 drives a first conical gear 35 to rotate under the action of a fourth rotating bearing 42, a second conical gear 36 rotates under the drive of the first conical gear 35, a lifting screw 20 rotates under the drive of the second conical gear 36, as an inner cavity of a screw cylinder 16 is connected with the outer wall of the lifting screw 20 through threads, the screw cylinder 16 drives the first lifting rod 12 to ascend under the rotation of the lifting screw 20, when the first lifting rod 12 ascends to a proper position, the support for the oral cavity of the patient is completed, thereby the operation is convenient to carry out, can reduce the friction when first lifter 12 ascends under the setting of gyro wheel 21, at third buffer spring 34, second buffer block 33, can play the effect of buffering protection to the first lifter 12 of lift under the setting of fourth buffer spring 38 and third buffer block 39, the movable sleeve that has made things convenient for first swivel bearing 4 and third buffer spring 34 under montant 32 sets up establishes, can play the effect of buffering to the patient's that supports oral cavity under the setting of first buffer spring 27 and second buffer spring 30, the setting of movable rod 25 conveniently drives compression block 23 and extrudes first buffer spring 27, stopper 28's setting can play spacing effect to first connecting block 10.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
