[0010] Furthermore, several of the second through holes connect to the second groove.

[0011] Furthermore, a first limiting member and a second limiting member are fixed on the second stamping plate. The first limiting member and the second limiting member are respectively disposed at opposite ends of the second stamping plate along the length direction. The forming mandrel is placed in the second groove, and the first limiting member and the second limiting member limit the forming mandrel.

[0012] Furthermore, the longitudinal section of the first limiting member is Y-shaped, including a first limiting arm and a second limiting arm, with an arc transition between the first limiting arm and the second limiting arm, the diameter of which is smaller than the outer diameter of the snake bone to be pressed.

[0035] The present invention discloses an endoscope snake bone pressing tool for making pressing grooves (traction holes) on both sides of the snake bone. The pressing grooves (traction holes) on both sides of the snake bone are used to pass through the traction wire that drives the snake bone to bend.

[0036] This utility model discloses an endoscope snake bone pressing tool, see [link to related document]. Figures 1-3Specifically, it includes an upper pressing assembly 1, a lower pressing assembly 2, and a forming mandrel 3. The upper pressing assembly 1 is fixed with several first punches 11 extending toward the lower pressing assembly 2, and the lower pressing assembly 2 is fixed with several second punches 21 extending toward the upper pressing assembly 1. The forming mandrel 3 is positioned on the lower pressing assembly 2 and is used to pass through the snake bone to be pressed. The first punches 11 and the second punches 21 are arranged on both sides of the snake bone to be pressed along the diameter direction. By pressing the first punches 11 fixed on the upper pressing assembly 1 and the second punches 21 fixed on the lower pressing assembly 2 with external force, the groove of the snake bone designed on the lower pressing assembly 2 is formed, and the required snake bone groove is finally obtained, which effectively improves the efficiency and accuracy of snake bone pressing.

[0037] In one embodiment of this utility model, the upper pressing assembly 1 includes a first pad 12 and a first stamping plate 13. The end face of the first stamping plate 13 facing the lower pressing assembly 2 has a first groove 131 extending along its length direction. The first stamping plate 13 also has first through holes 132 distributed along its length direction and penetrating its thickness direction. (See also...) Figure 4 It is important to understand here that the thickness direction refers to the direction towards the lower pressing component 2 and perpendicular to its length direction, and that several first through holes 132 connect to the first groove 131, and several first punches 11 are limited in the first through holes 132 and fixed to the first stamping plate 13 by the first pad 12.

[0038] In one embodiment of this utility model, the lower pressing assembly 2 includes a second pad 22 and a second stamping plate 23. A second groove 231 extending along its length is formed on the end face of the second stamping plate 23 facing the upper pressing assembly 1. When the upper pressing assembly 1 and the lower pressing assembly 2 cooperate to complete the pressing operation, the second groove 231 and the first groove 131 are positioned opposite each other, and the forming mandrel 3 is placed in the second groove 231. The second stamping plate 23 also has second through holes 232 distributed along its length and penetrating its thickness direction. (See also...) Figure 5 It is important to understand here that the thickness direction refers to the direction towards the upper pressing component 1 and perpendicular to its length direction, and that several second through holes 232 connect to the second groove 231, and several second punches 21 are limited in the second through holes 232 and fixed to the second stamping plate 23 by the second pad 22.

[0039] As an embodiment of this utility model, in order to fix the forming mandrel 3 onto the lower pressing assembly 2, a first limiting member 24 and a second limiting member 25 are also fixed on the second stamping plate 23. The first limiting member 24 and the second limiting member 25 are respectively disposed at opposite ends of the second stamping plate 23 along the length direction. It can be understood that the distance between the first limiting member 24 and the second limiting member 25 is adapted to the length of the forming mandrel 3; preferably, see Figure 7The longitudinal section of the first limiting member 24 is Y-shaped, including a first limiting arm 241 and a second limiting arm 242. The first limiting arm 241 and the second limiting arm 242 are connected by an arc, the diameter of which is smaller than the outer diameter of the snake bone to be pressed. (See also...) Figure 8 The second limiting member 25 has a limiting hole 251, and the diameter of the limiting hole 251 is smaller than the outer diameter of the snake bone to be pressed, so that the snake bone to be pressed can be fixed between the first limiting member 24 and the second limiting member 25, effectively preventing the snake bone to be pressed from moving along the length direction of the second stamping plate 23.

[0040] As an embodiment of this utility model, the outer peripheral surface of the molding mandrel 3 has pressing grooves 31 extending along its length direction on opposite sides along its diameter direction. See [reference needed]. Figure 6 Preferably, the first end 32 of the forming mandrel 3 is tapered to facilitate the insertion of the snake bone to be pressed, and the first end 32 is confined within the arc of the first limiting member 24; the end of the second end 33 of the forming mandrel 3 forms a limiting surface 331 to prevent the snake bone to be pressed from rotating in the tooling, and the second end 33 is confined within the limiting through hole 251 of the second limiting member 25.

[0041] The snake bone to be pressed is threaded onto the forming mandrel 3, and then the forming mandrel 3 with the snake bone to be pressed is placed in the second groove 231 on the second stamping plate 23, so that the first end 32 of the forming mandrel 3 is limited in the arc hole on the first limiting member 24, and the second end 33 is limited in the limiting hole 251 of the second limiting member 25. It is ensured that the pressing grooves 31 opened on opposite sides of the forming mandrel 3 along the diameter direction correspond to the first punch 11 and the second punch 21 respectively. By pressing the first punch 11 and the second punch 21 with external force, the part of the snake bone that is placed on the second stamping plate 23 and is limited to form a pressing groove is formed, and finally the required snake bone pressing groove is obtained.
