DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model provides a fixing device for a bone sawing machine as shown in FIGS. 1 to 5, comprising a mounting frame 1 and a bone sawing machine mainframe 2 on which the mounting frame 1 is mounted, the mounting frame 1 being movably arranged on the top of a cutting platform of the bone sawing machine mainframe 2, fixing frames 3 being fixed on both sides of an inner cavity of the mounting frame 1, a plurality of movable blocks 4 being arranged in the inner cavity of the fixing frame 3, a sliding through groove 5 being provided at the center of the movable block 4, a screw 6 being slidably connected to the inner cavity of the sliding through groove 5, the screw 6 being rotated in the inner cavity of the fixing frame 3 through a bearing, an extrusion plate 7 being threadedly connected to the surface of the screw 6 through a screw sleeve, a clamping column 8 for clamping and fixing bones being fixed on one side of the movable block 4, a frame body 9 being fixed on one side of the fixing frame 3, and a driving assembly 10 for synchronously driving the screw 6 being arranged in the inner cavity of the frame body 9;

By driving the three sets of screw rods 6 synchronously, the screw sleeve can be used to drive the clamping plate to move in the inner cavity of the fixed frame 3, squeeze the movable block 4, and keep the movable block 4 stable, so that the position of the clamping column 8 remains fixed, and the clamping column 8 is driven by the support spring 11 to fit the surface of the bone, so that the clamping column 8 fits the bone and limits the rotation of the bone. The clamping column 8 can not only clamp the bone to prevent the bone from moving left and right, but also cannot ensure the stability of the bone. At the same time, the clamping column 8 limits the rotation of the bone when it is cut, thereby improving the stability of the bone when it is divided.

The driving assembly 10 includes a worm 101 that rotates in the inner cavity of the frame 9 through a bearing. One end of the screw 6 passes through the inner cavity of the frame 9 and is fixed with a worm wheel 102. The worm wheel 102 is meshed with the opposite side of the worm 101. The top of the worm 101 passes through the frame 9 and is fixed with a handle 103. The worm 101 can be driven by rotating the handle 103. The worm 101 drives the worm wheel 102 to rotate to drive the screw 6. By adjusting the rotation direction of the handle 103, the rotation direction of the screw 6 can be adjusted, so that the position of the extrusion plate 7 can be adjusted using the screw sleeve.

A support spring 11 is fixed to the side of the movable block 4 away from the clamping column 8, and the other end of the support spring 11 is fixed to the inner cavity of the fixed frame 3. The setting of the support spring 11 facilitates the support of the movable block 4 to prevent the movable block 4 from sliding freely in the inner cavity of the fixed frame 3. At the same time, the movable block 4 and the clamping column 8 are attached to the surface of the bone under the drive of the support spring 11.

A slide groove 12 is provided at the top and bottom of the inner cavity of the fixed frame 3, and a slider 13 is slidably connected to the inner cavity of the slide groove 12. The opposite side of the slider 13 passes through the slide groove 12 and is fixed to the surface of the extrusion plate 7. The slider 13 slides in the inner cavity of the slide groove 12, which facilitates the limitation of the extrusion plate 7 and prevents the extrusion plate 7 from shaking in the fixed frame 3 due to the traction of the screw 6, making the extrusion force of various parts of the movable block 4 unbalanced, which may easily cause the movable block 4 to slide, affecting the clamping and fixing effect of the clamping column 8 on the bone.

Limiting frames 14 are arranged on both sides of the top of the cutting platform of the bone sawing machine main body 2, and limiting grooves 15 are opened on both sides of the installation frame 1. The limiting frames 14 extend to the inner cavity of the limiting grooves 15. The cooperation between the limiting frames 14 and the limiting grooves 15 facilitates the limiting of the installation frame 1 to prevent the installation frame 1 from shaking on the top of the cutting platform of the bone sawing machine main body 2, causing the saw blade and the bone to be stuck.

A mounting hole is provided at the bottom of the limit frame 14, and a mounting bolt 16 is movably provided in the inner cavity of the mounting hole. One end of the mounting bolt 16 passes through the mounting hole and is threadedly connected to the bone saw machine main body 2. The limit frame 14 can be detachably mounted on the surface of the bone saw machine main body 2 through the mounting bolt 16, and the fixing device can be removed from the bone saw machine main body 2.

The mounting frame 1 is located outside the saw blade of the bone sawing machine main body 2, and a handle 17 is fixedly installed on the front of the mounting frame 1. The setting of the handle 17 facilitates the movement of the mounting frame 1 to push the bone to contact the saw blade for cutting.

During specific use, the bone is placed in the installation frame 1, and then the two ends of the bone are inserted into the fixed frame 3. The bone contacts the clamping column 8 and pushes the clamping column 8 and the movable block 4 to slide in the inner cavity of the fixed frame 3. When the bone is neatly placed, the handle 103 is turned, and the handle 103 drives the worm 101 to rotate, and then the worm 101 drives the worm wheel 102 to rotate to drive the screw 6. The screw 6 drives the extrusion plate 7 to squeeze the movable block 4 through the screw sleeve, so that the movable block 4 remains stable under the action of friction, and then the movable block 4 and the clamping column 8 fix and limit the bone, and the handle 17 is used to push the installation frame 1, so that the installation frame 1 drives the bone to approach the saw blade of the bone sawing machine main body 2.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
