[0005] It comprises an operating handle and a spring tube arranged in the operating handle; wherein the spring tube is installed on the operating handle through a fixing structure; the fixing structure comprises a spring tube clamp and a locking nut arranged on the spring tube clamp; the spring tube clamp comprises a clamp tube and a chuck arranged at the end of the clamp tube, and an external thread is arranged at a portion of the clamp tube close to the chuck; a clamping ring is arranged in the locking nut, the chuck is composed of four jaws, and the chuck is conical as a whole, and the inner ring surface of the clamping ring is arranged as an inclined surface.

[0006] Furthermore: a fastening structure is also provided on the operating handle, and the fastening structure includes a slot for installing the spring pipe clamp, a threaded hole connected to the slot, and a fastening bolt is provided in the threaded hole.

[0007] Furthermore: a rocker structure is also arranged in the operating handle, a clamping bolt is arranged on the rocker structure, a soft steel wire rope is arranged in the spring tube, and one end of the soft steel wire rope is fixed to the rocker structure through the clamping bolt.

[0008] Further: a fixing seat is provided on the operating handle, and the spring pipe clamp is installed on the operating handle through the fixing seat.

[0009] The beneficial effects are:

[0010] The new structure cancels the stainless steel tube and replaces it with a spring tube clamp made of brass. This tube clamp has a circular outer diameter, a certain taper at one end, and a slot at this end; the other end is a threaded structure; and with a locking nut, the spring tube clamp and the spring tube are pressed together by compression to form a blocking effect. The pressure given by the compression method is relatively reliable and can play a good blocking role. And the tapered slotted end is outside the structure, which is easy to disassemble and repair.

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0020] See also Figure 1-4 This is an embodiment of the spring tube fixing device for an endoscope probe of the utility model.

[0021] It includes an operating handle 1 and a spring tube 2 arranged in the operating handle 1; wherein the spring tube 2 is installed on the operating handle 1 through a fixing structure 3; the fixing structure 3 includes a spring tube clamp 4 and a locking nut 5 arranged on the spring tube clamp 4; the spring tube clamp 4 includes a clamp tube 41 and a clamp head 42 arranged at the end of the clamp tube 41, and an external thread 43 is arranged at the position of the clamp tube 41 close to the clamp head 42; a clamping ring 6 is arranged in the locking nut 5, the clamp head 42 is composed of four clamping claws, and the clamp head 42 is conical as a whole, and the inner ring surface of the clamping ring 6 is arranged as an inclined surface.

[0022] After the spring tube 2 of the device passes through the spring tube clamp 4, a locking nut 5 with a hole is added in front of the spring tube clamp 4. The locking nut 5 presses the spring tube clamp 4 inward. The taper and pressure at the front end of the spring tube clamp 4 can cause the spring tube clamp 4 to deform and hold the spring tube 2 in its hole.

[0023] Specifically, the internal thread of the locking nut 5 rotates in coordination with the external thread 43 of the clamp tube 41, and the clamping ring 6 on the locking nut 5 presses on the chuck 42 composed of four clamping claws, so that the chuck 42 holds the spring tube 2 under pressure; in this way, the fixation of the spring tube 2 is completed; the device is easy to operate, and when the spring tube 2 is subsequently disassembled, it is only necessary to twist the locking nut 5.

[0024] A fixing seat 11 is provided on the operating handle 1, and the spring pipe clamp 4 is installed on the operating handle 1 through the fixing seat 11; a fastening structure 7 is also provided on the operating handle 1, and the fastening structure 7 includes a slot 71 for installing the spring pipe clamp 4, a threaded hole 72 connected to the slot 71, and a fastening bolt 73 is provided in the threaded hole 72.

[0025] The spring pipe clamp 4 is set in the slot 71, and then the fastening bolt 73 in the threaded hole 72 can be tightened, and the fastening bolt 73 will be pressed on the outside of the spring pipe clamp 4, so that the spring pipe clamp 4 is fixed in the slot 71; therefore, the device is also very convenient for replacing the spring pipe clamp 4.

[0026] It also avoids the spring pipe clamp from shaking up and down during use, which affects the use. At the same time, it also reduces the use of glue (to prevent loosening) in the spring pipe clamp 4, making it more convenient to disassemble and repair in the later stage.

[0027] A rocker structure 8 is also provided in the operating handle 1 , and a clamping bolt 9 is provided on the rocker structure 8 . A soft steel wire rope 10 is provided in the spring tube 2 , and one end of the soft steel wire rope 10 is fixed to the rocker structure 8 through the clamping bolt 9 .

[0028] The function of the soft steel wire rope 10 is the control line of the industrial endoscope, which is convenient for controlling the bending direction of the snake tube; the soft steel wire rope 10 of this device is fixed to the rocker structure 8 by the tightening bolt 9, and the staff can adjust the direction of the rocker structure 8 to achieve the purpose of adjusting the bending direction of the snake tube.

[0029] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
