[0030] How this utility works:

[0031] When in use, first place the instrument to be repaired on the support frame 2, and then the staff can pull the first pull block until the fixed plug rod 14 moves out of the fixed plug hole and releases the vertical slide bar 6. At this time, the height of the clamping plate 9 can be adjusted by moving the vertical slide bar 6 up and down. When it is adjusted to a suitable height, release the first pull block, and under the elastic force of the return tension spring 15, the first pull block will be pulled to automatically reset, and then the fixed plug rod 14 can be driven to automatically move into the fixed plug hole to fix the vertical slide bar 6. Then, the staff can pull the second pull block, and the movement of the second pull block will drive the locking block 19 to disengage from the locking gear 16 through the hexagonal slide bar 18, and release the locking gear 16 and the horizontal screw rod 3. At this time, the staff can turn the control knob 11, and the rotation of the control knob 11 will drive one of the horizontal screw rods 3 to rotate, and the first bevel gear 12 and multiple second bevel gears 13 will rotate. Under the joint action, the remaining multiple horizontal screw rods 3 will be driven to rotate synchronously. The synchronous rotation of multiple horizontal screw rods 3 will drive multiple moving blocks 4 to move toward or away from each other at the same time, and then the multiple clamping plates 9 can be driven to move toward or away from each other through the fixed sleeve 5, the vertical slide bar 6, the connecting sleeve 7 and the horizontal slide bar 8. With the cooperation of the extrusion spring 10, instruments of different sizes can be clamped and fixed. After clamping and fixing, the second pull block can be directly released. Under the elastic force of the reset spring 20, the hexagonal slide bar 18 can be automatically reset by squeezing the convex piece, and then the locking block 19 can be driven to engage with the locking gear 16, so that the locking gear 16 and the horizontal screw rod 3 are always locked and cannot be rotated, so as to avoid the loosening of the instrument due to accidentally touching the control knob 11 during use. The operation is simple and convenient, saving time and effort, improving work efficiency, and having good practicality.
