When the knocking link 50 is to be inserted into the second through hole 22, the second through hole 22 forms a passage through which the knocking link 50 passes after an upward force is applied to the catching member 40 to move the catching member 40 upward.
When the knocking connecting rod 50 is positioned in the second through hole 22, the clamping piece 40 moves downwards under the action of the spring 43, and the upper end wall of the third through hole 23 is clamped into the groove of the knocking connecting rod 50.
The limiting block 12 positioned below is provided with a fourth through hole 24.
The holder of this embodiment may be used in conjunction with an instrument holder 60. Instrument holding devices can be found in patent No. cn201910562914.x, which discloses a special instrument holding device for use with an orthopaedic surgical robot. The holder of this embodiment, in use, may be mated with the instrument holding device disclosed in the patent.
The holder of this embodiment is typically used by first securing the instrument holder 60 and then securing the intramedullary canal file 20 to the holder of this embodiment. Of course, it is also possible to secure the intramedullary canal file first and then to the instrument holder.
When the holder of the present embodiment is empty, the state of the catching member 40 is as shown in fig. 6; the upper end wall of the third through hole 23 is positioned in the second through hole 22 under the action of the spring 43, the third through hole 23 and the second through hole 22 are staggered downwards, and the latch pin 42 abuts against the upper end wall of the kidney-shaped hole.
Then, the button 45 is pressed, the snap 40 moves upward, and the second through hole 22 forms a passage through which the striking link 50 passes. The knocking link 50 is inserted into the second through hole.
Then, the button 45 is released, the snap-in member 40 moves downward by the spring 43, and the upper end wall of the third through hole 23 is snapped into the groove of the knocking link 50. Thus, the holder of the present embodiment is fixed to the tapping link 50. The state between the gripper and the striking link is shown in fig. 7.
When the clamp holder and the knocking connecting rod of the embodiment need to be detached, the button 45 is pressed to pull out the knocking connecting rod, and the clamp holder and the knocking connecting rod of the embodiment can be separated.
The head 61 of the instrument holder 60 is a rectangular parallelepiped having a square cross section. The head 61 of the instrument holding device is inserted between the two stoppers 12.

The other end of the knocking connecting rod is positioned outside the instrument clamping device, and a knocking disc is arranged at the end part of the knocking connecting rod. When the intramedullary nail is used, external force can act on the knocking disc and push the knocking connecting rod to move towards the direction of the medullary cavity file. When the external force disappears, the instrument clamping device can enable the knocking connecting rod to rebound to the original position. Because the length of the limiting block is greater than the maximum axial moving distance of the knocking connecting rod in the instrument clamping device, when external force is applied to the knocking connecting rod, the directional knocking device is protected from being separated from the head of the instrument clamping device by the eight-gear intramedullary cavity file stroke. In this way, the stroke protection function is realized.
Because the striking rod can only move axially in the instrument holding device, the directional movement of the device of the present invention during striking can be achieved.
