[0008] Preferably, the matching component includes two groups of positioning plates arranged on the outer periphery of the bone drill body. A matching sleeve is sleeved at the position of the positioning plates. A fixing ring is arranged on the upper part of the matching sleeve.

[0009] Among them, the fixing ring connects and fixes the matching sleeve to the outer periphery of the positioning plate.

[0010] Preferably, internal threads are provided on the inner periphery of the lower part of the fixing ring, and external threads are provided on the outer periphery of the upper part of the matching sleeve. The internal threads and the external threads cooperate with each other, so that the fixing ring and the matching sleeve are connected by threads.

[0011] Preferably, the outer diameter of the fixing ring is smaller than the outer diameter of the matching sleeve.

[0012] Preferably, clamping grooves for cooperating with the positioning plates are provided on both sides of the inner wall of the matching sleeve, and force - increasing threads for increasing force are provided on the outer periphery of the matching sleeve.

[0013] Preferably, the force increasing member includes a guide rod located between two groups of load-bearing rods. A force increasing cylinder is arranged in the middle of the guide rod, and a guide thread matching with the force increasing thread is arranged on the inner wall of the force increasing cylinder.

[0027] Please refer to Figures 1-4 , the present utility model provides a guiding and force increasing bone drill, including a stabilizing frame 1 and a bone drill body 4. Two groups of bearing rods 2 are arranged on one side of the stabilizing frame 1. The bearing rods 2 are connected to the bone drill body 4 through a force increasing member 3. A fitting 5 is arranged on the outer periphery of the bone drill body 4.

[0028] The force increasing member 3 includes a guiding rod 301 located between the two groups of bearing rods 2. A force increasing cylinder 302 is arranged in the middle of the guiding rod 301. A guiding thread 303 is provided on the inner wall of the force increasing cylinder 302 and is matched with a force increasing thread 5023.

[0029] Guiding grooves 201 for the linear movement of the guiding rod 301 are provided on the opposite sides of the bearing rods 2, and a force increasing spring 6 is arranged above the guiding rod 301 in the guiding grooves 201.

[0030] A handle 101 for an operator to hold is arranged in the middle of the stabilizing frame 1.

[0031] The fitting 5 includes two groups of positioning plates 501 arranged on the outer periphery of the bone drill body 4. A fitting sleeve 502 is sleeved at the positioning plates 501. A fixing ring 503 is arranged at the upper part of the fitting sleeve 502.

[0032] An internal thread 5031 is provided on the lower inner circumference of the fixing ring 503, and an external thread 5021 is provided on the upper outer circumference of the mating sleeve 502. The internal thread 5031 and the external thread 5021 cooperate with each other so that the fixing ring 503 and the mating sleeve 502 are threadedly connected. The outer diameter of the fixing ring 503 is smaller than the outer diameter of the mating sleeve 502. Card slots 5022 that cooperate with the positioning plate 501 are provided on both sides of the inner wall of the mating sleeve 502, and a force-increasing thread 5023 for increasing force is provided on the outer circumference of the mating sleeve 502.
