[0027] In view of the problems in the prior art, the utility model provides a kind of pre-oxidized fiber equipment with high stability, which comprises body 1, glass combustion cylinder 2 is sleeved outside body 1, clamping mechanism is arranged outside body 1, clamping mechanism includes mounting plate 3, long plate 4, screw 5 and clamping plate 6, two mounting plates 3 are fixedly installed outside body 1, long plate 4 is fixedly installed outside body 1, long plate 4 is between two mounting plates 3, screw 5 is rotatably connected at the outside of two mounting plates 3, two clamping plates 6 are screw-connected outside screw 5, clamping plate 6 is composed of cuboid plate and semicircular groove on cuboid plate, two clamping plates 6 are slidably connected outside long plate 4 close to one end of screw 5, circular ring 7 is fixedly installed outside glass combustion cylinder 2, circular ring 7 is located at the lower surface of two clamping plates 6, by setting clamping plate 6, cooperate screw 5, when glass combustion cylinder 2 is working, rotate screw 5 to drive two clamping plates 6 to move to glass combustion cylinder 2 until two clamping plates 6 clamp and fix glass combustion cylinder 2, so when user accidentally collides with glass combustion cylinder 2, because two clamping plates 6 fix the upper end of glass combustion cylinder 2, and circular ring 7 is located at the lower surface of two clamping plates 6, glass combustion cylinder 2 cannot move upward at the same time glass combustion cylinder 2 cannot tilt to the side, so the stability of glass combustion cylinder 2 is improved, and the accuracy of test result is ensured.

[0028] Slip groove 8 is formed in the outside of each clamping plate 6, clamping plate 6 is slidably connected outside long plate 4 through slip groove 8, two limit discs 9 are fixedly installed outside screw 5, two limit discs 9 are located at the two ends of mounting plate 3, to avoid the connection between screw 5 and mounting plate 3 being released.

[0029] The outer part of the screw rod 5 is fixedly provided with a handle 10, which facilitates the user to rotate the screw rod 5. The handle 10 is located at the end of the screw rod 5 away from the limiting disc 9. The outer part of the handle 10 is rotatably connected with a rotating shaft 11. The outer part of the rotating shaft 11 is fixedly provided with a fixing frame 12. The fixing frame 12 is composed of a frame-shaped body and a cuboid. The side of the machine body 1 close to the handle 10 is provided with a groove 13. The inner part of the groove 13 is fixedly connected with a spring 14. The outer part of the spring 14 is fixedly connected with a fixing plate 15. The fixing plate 15 is composed of a T-shaped body and a cuboid plate. The fixing plate 15 is slidably connected to the inner side of the fixing frame 12. By arranging the handle 10 and cooperating with the fixing plate 15, when the machine body 1 is moved, the clamping plate 6 clamps and fixes the glass combustion cylinder 2. At this time, the fixing plate 15 is moved away from the handle 10, the spring 14 is compressed, the fixing frame 12 is rotated to stand up, the fixing plate 15 is loosened, and the fixing plate 15 is moved under the action of the spring 14 until the fixing plate 15 is slidably connected to the inner side of the fixing frame 12.

[0031] Working principle:

[0032] Firstly, when the glass combustion cylinder 2 is sleeved on the machine body 1, the handle 10 is rotated to drive the screw rod 5. At this time, the screw rod 5 drives the two clamping plates 6 to move towards the glass combustion cylinder 2 until the protective pads 16 are tightly attached to the glass combustion cylinder 2. At this time, the glass combustion cylinder 2 is clamped and fixed. In this process, the end of each clamping plate 6 close to the screw rod 5 is slidably connected to the outer part of the long plate 4, which ensures that the clamping plate 6 does not rotate downward during the movement. Therefore, when the user accidentally collides with the glass combustion cylinder 2, the glass combustion cylinder 2 cannot move upward due to the combined action of the clamping plate 6 located on the upper surface of the circular ring 7 and the circular ring 7. At the same time, because the upper end of the glass combustion cylinder 2 is fixed and cannot move, it also cannot tilt to the side. The stability of the glass combustion cylinder 2 is improved, and the accuracy of the test results is ensured.

[0033] Secondly, when the machine body 1 is moved, the fixing plate 15 is moved away from the handle 10, the spring 14 is compressed, the fixing frame 12 is rotated to stand up, the fixing plate 15 is loosened, and the fixing plate 15 is moved under the action of the spring 14 until the fixing plate 15 is slidably connected to the inner side of the fixing frame 12. At this time, the handle 10 is fixed.

[0034] Finally, it should be noted that: apparently, the above embodiments are merely examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made. Here, it is not necessary and impossible to exhaust all the implementation. The obvious changes or variations derived from it are still within the protection scope of the utility model.
