[0031] In the related art, when the mesh tail of the therapeutic instrument handpiece housing is connected to the handpiece wire 20, the handpiece wire 20 is often directly pressed against the handpiece housing by clamping and tightening the handpiece wire 20. In this arrangement, since the handpiece wire 20 is deformed by the clamping and tightening, the inner core part of the handpiece wire 20, such as the trachea 21, is at risk of deformation and failure.
[0032] The utility model provides a hand tool fixing assembly 100 .
[0033] See also Figure 1 and Figure 2 In one embodiment of the present invention, the hand tool fixing assembly 100 is used to fix the wire 20 including the air tube 21 to the hand tool housing 30, and the hand tool fixing assembly 100 includes:
[0034] A sheath 10, wherein the sheath 10 is embedded in the inner wall of the wire 20, and a hollow passage 111 is formed in the sheath 10 for the trachea 21 to pass through;
[0035] The hand tool housing 30 contacts the outer wall of the wire 20 and applies a certain force to the wire 20 and the sheath 10 to tighten the wire 20 while the hollow channel 111 is not deformed under the force.
[0036] The technical solution of the utility model fixes the wire 20 including the trachea 21 to the hand tool housing 30 by adopting a hand tool fixing assembly 100. The hand tool fixing assembly 100 includes a sheath 10 for being embedded in the inner wall of the wire 20. A hollow channel 111 for the trachea 21 to pass through is formed in the sheath 10. With such an arrangement, when the hand tool housing 30 contacts the outer wall of the wire 20 and applies a certain force to the wire 20 and the sheath 10 to tighten the wire 20, the hollow channel 111 of the sheath 10 may not be deformed and may protect the trachea 21 passing through it, thereby preventing the trachea 21 structure inside the wire 20 from being deformed and failing, thereby improving the protection performance of the hand tool fixing assembly 100.
[0037] See also Figure 1 and Figure 2 In an embodiment of the present utility model, the sheath 10 comprises:
[0038] The sleeve portion 11 is embedded in the port of the wire 20 and abuts against the inner wall of the port; and
[0039] The flange portion 12 is protrudingly provided at one end of the sleeve portion 11 , and radially extends away from the center of the sleeve portion 11 and abuts against the port.
[0040] The sleeve body is a hollow tubular structure, and a hollow passage 111 is formed in the sleeve body for the air pipe 21 to pass through. The sleeve body 11 is embedded in the port of the wire 20 and arranged around the circumference of the wire 20 so that the outer wall of the sleeve body and the inner wall of the port abut against each other, thereby improving the protection performance of the wire 20 without affecting the passage of the air pipe 21 in the wire 20. The flange portion 12 is protruded at one end of the sleeve body 11, and radially extends away from the center of the sleeve body 11 and abuts against the port, thereby facilitating the installation of the sleeve 10 and improving the installation stability between the sleeve 10 and the wire 20.
[0041] See also Figure 1 and Figure 2 In an embodiment of the present invention, the sheath 10 comprises a rigid material.
[0042] Among them, by making the sheath 10 include rigid materials, the strength performance of the sheath 10 can be improved, and the sheath 10 is not easily deformed due to force. Therefore, the protection performance of the wire 20 can be improved by embedding the sheath 10 in the inner wall of the wire 20. Common rigid materials can be metals or metal alloys to make the sheath 10.
[0043] See also Figure 1 and Figure 2In an embodiment of the utility model, in the hollow channel 111 , an isolation layer is filled between the inner wall of the sheath 10 and the trachea 21 to prevent the trachea 21 from moving with the wire 20 when the wire 20 moves.
[0044] The outer wall of the trachea 21 and the inner wall of the sheath 10 are spaced apart, and an isolation layer is filled between the two. The isolation layer can be, but is not limited to, an elastic material such as cotton. In this way, when the wire 20 moves, the isolation layer can prevent the trachea 21 from moving, which is beneficial to improve the installation stability between the trachea 21 and the sheath 10. In one embodiment, the isolation layer is a soft rubber ring, which is arranged in a groove provided on the inner wall of the sheath 10 and elastically abuts between the inner wall of the sheath 10 and the trachea 21, so as to prevent the trachea 21 from moving with the wire 20 when the wire 20 moves.

The fastener 31 is fixed to the hand tool housing 30 and is ringed around the outer wall of the wire 20, and applies a certain tightening force to the wire 20 and the sheath 10.
[0046] The fastener 31 is a hollow ring structure and is arranged around the circumference of the wire 20, and is used to be arranged around and pressed against the outer wall of the wire 20 to apply a certain fastening force to the wire 20 and the sheath 10. In this way, the fastening force applied by the fastener 31 to the wire 20 and the sheath 10 can fix the wire 20 in the hand tool housing 30, and because the sheath 10 is embedded in the inner wall of the wire 20 and the hollow channel 111 in the sheath 10 will not be deformed by the fastening force applied by the fastener 31, the connection stability between the hand tool housing 30 and the wire 20 can be ensured while reducing the risk of deformation and failure of the trachea 21 passing through the hollow channel 111.

By making the first pressure block 311 and the second pressure block 312 arranged around the port side of the wire 20, the first pressure block 311 and the second pressure block 312 are squeezed against each other by external force, and a fastening force can be applied to the outer periphery of the wire 20, so that the wire 20 can be stably limited between the first pressure block 311 and the second pressure block 312.
[0050] Furthermore, in an embodiment of the present invention, the first pressing block 311 and the second pressing block 312 are connected by threads.
[0051] Specifically, the first pressing block 311 and the second pressing block 312 can be detachably connected by a set screw, but are not limited to the set screw. By tightening the set screw, the first pressing block 311 and the second pressing block 312 can be closely matched with each other so that they can be pressed against the peripheral side of the hand tool wire 20.
[0052] See also Figure 1 and Figure 2 In an embodiment of the utility model, the fastener 31 also includes at least a first pin 313 and a second pin 314, the first pin 313 sequentially penetrates the first pressure block 311 and the wire 20 to abut the sheath 10, and the second pin 314 sequentially penetrates the second pressure block 312 and the wire 20 to abut the sheath 10.
[0053] Among them, by providing the first pin 313, and making the first pin 313 pass through the first pressing block 311 and the wire 20 in sequence to abut the sheath 10, it can play a role in fixing the first pressing block 311, the wire 20 and the sheath 10; similarly, by providing the second pin 314, and making the second pin 314 pass through the second pressing block 312 and the wire 20 in sequence to abut the sheath 10, it can play a role in fixing the second pressing block 312, the wire 20 and the sheath 10. Such a setting can further improve the limiting effect of the fastener 31 on the wire 20, reduce the risk of the wire 20 detaching from the fastener 31 and falling out of the hand tool housing 30, and is conducive to improving the structural stability of the hand tool fixing assembly 100.
[0054] See also Figure 1 and Figure 2In an embodiment of the utility model, the first latch 313 and the second latch 314 are provided with external threads, and the first pressure block 311 and the second pressure block 312 are correspondingly provided with internal threads. The first latch 313 sequentially penetrates the first pressure block 311 and the wire 20 through threaded cooperation to abut against the sheath 10, and the second latch 314 sequentially penetrates the second pressure block 312 and the wire 20 through threaded cooperation to abut against the sheath 10.
[0055] Specifically, the first latch 313 and the second latch 314 can be, but are not limited to, set screws, and the outer peripheral surface of the set screws is provided with external threads; the first pressure block 311 and the second pressure block 312 can be provided with threaded holes correspondingly, and the inner side walls of the threaded holes are provided with internal threads.
