This creation provides a designer of the shaft structure for quick clamps.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the implementation method and the detailed description of the drawings as follows: See the first to seventh figures, this creation provides a quick The shaft structure of the clamp comprises: a shaft 10, the shaft 10 is coupled with a fixing block 11 at one end thereof, and the other end of the shaft 10 is coupled with a fixing clamp 50. The shaft 10 is provided with at least one slot 12 connected thereto. A hollow passage 13 is formed in the inner portion of the shaft 10. The fixed block 11 is held by a spring 111 to limit one end of the traction member 20. The movable rod holder 30 is slid on the shaft 10, and a clamping structure 40 is formed. The 掣 structure 40 is slidably disposed in the hollow passage 13 of the shaft 10, and the clamping structure 40 can normally fix the traction member 20, and the clamping structure 40 is fixedly integrated with the movable clamping seat 30 through the slot 12 of the shaft 10, the foregoing The fixing clamp 50 is sleeved on the free end of the shaft 10, and the free end of the traction member 20 is fixed to an elastic rod 21. The elastic rod 21 is inserted through the fixed clamping seat 50 and is pivoted to one of the eccentric operating handles 60. The operating handle 60 presses the free end of the clamping seat 50 to the concave end 51, and the eccentric operating handle 60 swings the pulling member 20 and the movable clamping seat 30 to clamp the object in the direction of the fixed clamping seat 50. The main reason is that the traction member 20 is a steel straight rod body, and the traction member 20 is disposed on the shaft rod 1 0 Internal hollow passage 13, the shaft 10 can be polygonal, circular or square, and the shaft 10 is at least one shaft 10 of the slot 12, according to which the clamping structure 40 is pulled by the hollow passage 13 of the shaft 10. At 20, it is fixed to the movable holder 30 via the aforementioned slot 12.

Referring to the third figure, the shaft 10 is formed as a circular shaft 10a, and the circular shaft 10a is provided with two slits 12.

Referring to the fourth figure, the shaft 10 is made into a circular shaft. 10a, and its circular shaft 10a is provided with three slits 12.

Referring to the fifth figure, the shaft 10 is formed as a square shaft 10b, and the square shaft 10b is provided with two slits 12.

Referring to the second and sixth figures, a movable button 30 is provided with a button 31. When the button 31 is depressed, the swing arm 32 is controlled to push back against the clamping mechanism 40. The locking member 20 is unlocked, and at the same time, the movable holder 30 can be adjusted to the desired position or abut against the object 70 to be clamped while the button 31 is kept depressed.

Referring to the second, sixth and seventh figures, when the movable clamp 30 is pressed against the object 70, the depressed button 31 is released, and the clamp positioning member 43 immediately locks the traction member 20, and then the panel is clamped. The eccentric operating handle 60 is rotated, and the eccentric operating handle 60 is rotated to be eccentric to generate a pulling force transmitted to the clamping structure 40 and the movable clamping seat 30 via the pulling member 20, so that the movable clamping seat 30 can clamp the object 70.
