[0014] (III) Beneficial Effects
[0015] This utility model provides a fixing structure for the production of flexible transmission shafts. It has the following beneficial effects:
[0016] 1. By using a fixed assembly and a geared motor to drive the threaded rod to rotate, the rotation of the threaded rod causes the threaded sleeve to move up and down, thereby causing the moving block to move up and down for easy adjustment. By rotating the locking bolt, the wedge at one end of the locking bolt contacts the end of the clamping spring by the interlocking action between the locking bolt and the threaded sleeve. The locking bolt moves within the threaded sleeve, causing the wedge to continuously compress the clamping spring, thus fixing the clamping spring to the transmission flexible shaft. This allows for the clamping and fixing of transmission flexible shafts of different sizes, facilitating subsequent processing operations and improving the practicality of the device.
[0017] 2. The clamping assembly, via a rotating lever, drives the rotating disk to rotate. The interaction between the fixed rod and the moving groove allows the rotating disk to move the fixed rod within the moving groove. The interaction between the arc-shaped groove and the limiting rod allows the rotating disk to slide the limiting rod within the arc-shaped groove, thereby moving the fixed frame. The fixed frame then moves the moving rod up and down, causing the hinged seat to rotate the rotating plate. The rotating plate, through the interaction between the L-shaped slide rail and the slide rod, moves between the two fixed plates. The rotating plate then drives the connecting block to rotate, achieving a 90° rotation of the clamping block. This allows the clamping block to hold the transmission flexible shaft on the clamping groove, improving the device's practicality. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] Example 1
[0027] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a fixed structure for the production of transmission flexible shaft, including a base plate 1. A groove 101 is provided on the upper surface of the base plate 1. A bidirectional screw 102 is rotatably arranged in the groove 101. A fixing component 2 is threadedly connected to the outer surface of the bidirectional screw 102. A clamping component 3 is fixedly connected to the middle of the upper surface of the base plate 1.
[0028] The fixing component 2 includes a movable frame 201 threaded onto the outer surface of the bidirectional screw 102. A threaded rod 202 is inserted inside the movable frame 201. A threaded sleeve is threaded onto the outer surface of the threaded rod 202. A movable block 203 is fixedly fitted onto the outer surface of the threaded sleeve. A threaded sleeve 204 is fixedly connected to the outer surface of the movable block 203. A through groove is opened inside the threaded sleeve 204. A fixed plate 205 is fixedly connected to the bottom wall of the through groove. Clamping springs 206 are arranged in a ring array on the outer surface of the fixed plate 205. A locking bolt 207 is threaded onto the inside of the threaded sleeve 204. A fixing groove 208 is opened inside the locking bolt 207.
[0029] Specifically, the end of the clamping spring 206 away from the fixed plate 205 is inclined, and a wedge is provided at one end of the locking bolt 207, and the wedge cooperates with one end of the clamping spring 206.
[0030] Furthermore, through the fixed component 2, the reduction motor 209 drives the threaded rod 202 to rotate. The rotation of the threaded rod 202 drives the threaded sleeve to move up and down, thereby driving the moving block 203 to move up and down for easy adjustment. By rotating the locking bolt 207, the wedge at one end of the locking bolt 207 contacts one end of the clamping spring 206 through the mutual cooperation between the locking bolt 207 and the threaded sleeve 204. The locking bolt 207 moves within the threaded sleeve 204, causing the wedge to continuously squeeze the clamping spring 206, thereby fixing the clamping spring 206 to the transmission flexible shaft. This allows for the clamping and fixing of transmission flexible shafts of different sizes, facilitating subsequent processing operations and improving the practicality of the device.
[0031] Example 2
[0032] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0033] The clamping assembly 3 includes a fixing frame 301 fixedly connected to the upper surface of the base plate 1. The upper surface of the fixing frame 301 is provided with a clamping groove 302. Fixing plates 304 are symmetrically arranged on the upper surface of the fixing frame 301. A rotating plate 305 is arranged between the two fixing plates 304. A connecting block 306 is fixedly connected to the upper surface of the rotating plate 305. A clamping block 307 is inserted through the outer surface of the connecting block 306. A moving rod 303 is inserted through the upper surface of the fixing frame 301. A hinge seat 308 is fixedly connected to one end of the moving rod 303. One end of the rotating plate 305 is hinged to the hinge seat 308.
[0034] Specifically, a fixed frame 311 is fixedly connected to the end of the movable rod 303 away from the hinge seat 308. A movable groove 312 is formed on the outer surface of the fixed frame 311. A rotating disk 313 is movably arranged inside the fixed frame 311. A fixed rod 314 is inserted into the rotating disk 313, with both ends of the fixed rod 314 passing through the movable groove 312 and extending to the outside of the fixed frame 301. An arc-shaped groove 315 is formed on the outer surface of the rotating disk 313. A limiting rod 316 is fixedly connected to the inner wall of the fixed frame 311, and the limiting rod 316 is slidably connected to the arc-shaped groove 315. A lever 317 is fixedly connected to the outer surface of the rotating disk 313. L-shaped slide rails 309 are fixedly connected to opposite sides of the two fixed plates 304. A slide rod 310 is fixedly connected to the side wall of the 05, and one end of the slide rod 310 is slidably connected to the L-shaped slide rail 309. The rotating plate 305 is rotatably connected to the fixed plate 304 through the slide rod 310 and the L-shaped slide rail 309. A limiting slide groove 104 is opened on the inner side wall of the groove 101. A limiting slider 210 is fixedly connected to the outer surface of the moving frame 201. The moving frame 201 is slidably connected to the groove 101 through the limiting slider 210 and the limiting slide groove 104. A drive motor 103 is fixedly connected to one side of the base plate 1, and the output end of the drive motor 103 is connected to the bidirectional screw 102. A reduction motor 209 is provided on the top of the moving frame 201, and the output end of the reduction motor 209 is connected to the threaded rod 202.
[0035] Furthermore, through the clamping assembly 3, the rotating lever 317 drives the rotating disk 313 to rotate. The cooperation between the fixed rod 314 and the moving groove 312 causes the rotating disk 313 to move the fixed rod 314 within the moving groove 312. The cooperation between the arc-shaped groove 315 and the limiting rod 316 causes the rotating disk 313 to slide the limiting rod 316 within the arc-shaped groove 315, thereby moving the fixed frame 311. The fixed frame 311 then moves the moving rod 303 up and down, causing the hinge seat 308 to rotate the rotating plate 305. The rotating plate 305, through the cooperation between the L-shaped slide rail 309 and the slide rod 310, moves between the two fixed plates 304. The rotating plate 305 then drives the connecting block 306 to rotate, achieving a 90° rotation of the clamping block 307. This allows the clamping block 307 to clamp the transmission flexible shaft on the clamping groove 302, improving the practicality of the device.
[0036] Working principle: In use, the operator starts the drive motor 103 to drive the bidirectional screw 102 to rotate. The cooperation between the limiting slide groove 104 and the limiting slider 210 causes the moving frame 201 to move within the groove 101, thus adjusting according to the size of the transmission flexible shaft. The end of the transmission flexible shaft is then inserted into the threaded sleeve 204 through the fixing groove 208. By rotating the locking bolt 207, the cooperation between the locking bolt 207 and the threaded sleeve 204 allows for clockwise rotation. The locking bolt 207 is tightened so that the wedge at one end of the locking bolt 207 contacts the clamping spring 206 at one end. The locking bolt 207 moves within the threaded sleeve 204, causing the wedge to continuously press against the clamping spring 206, thereby fixing the flexible shaft. This allows for the clamping and fixing of flexible shafts of different sizes. The geared motor 209 drives the threaded rod 202 to rotate, which in turn causes the threaded sleeve to move up and down, thereby causing the moving block 203 to move up and down. The flexible shaft is adjustable to accommodate users of different heights. The outer side of the transmission shaft is placed in the clamping groove 302. Rotating the lever 317 drives the rotating disk 313 to rotate. The interaction between the fixed rod 314 and the moving groove 312 causes the rotating disk 313 to move the fixed rod 314 within the moving groove 312. The interaction between the arc-shaped groove 315 and the limiting rod 316 causes the rotating disk 313 to slide the limiting rod 316 within the arc-shaped groove 315, thereby moving the fixed frame 313. 11. The fixed frame 311 moves the moving rod 303 up and down, causing the hinge seat 308 to drive the rotating plate 305 to rotate. The rotating plate 305 moves between the two fixed plates 304 through the cooperation between the L-shaped slide rail 309 and the slide rod 310. The rotating plate 305 drives the connecting block 306 to rotate, realizing the 90° rotation of the clamping block 307. Thus, the clamping block 307 is used to clamp the transmission flexible shaft on the clamping groove 302, improving the practicality of the device.
