Improved release structure of fixture limit

This creation is related to a fixture structure, especially a release structure improvement of a labor-saving clamp limit.

According to a conventional clamp structure, as shown in FIG. 7, the clamp 50 is mainly connected with a fixed clamp arm 52 and a movable clamp arm 53 by a long rod 51. The movable clamp arm 53 is connected with a clamping block 54. With a pressing handle 55, the pressing handle 55 can be pressed to press the clamping block 54 toward the fixing clamp arm 52, and a rack 531 is fixed to the movable clamping arm 53, and the pressing handle 55 is pivotally connected by a shaft 551. A release button 56 is provided, and the release button 56 is toothed with the tooth 561 at one end, and a spring 57 is disposed on the other end of the release button 56. When the article is to be clamped, the pressure handle 55 is applied. The force is rotated downward by the swaying handle 55. During the swaying, the teeth 561 of the release button 56 are locked with the rack 531 of the movable clamp arm 53 at any time to ensure that the clamping process is not loose. When the article is to be removed, the pressing is provided through the pressing handle 55, so that the release button 56 can be lifted up at the other end of the tooth 561, and then the release button 56 is pressed to make the tooth 561 and the rack 531. If the detachment occurs, the movable clamp arm 53 can be retracted by the synchronization. However, it is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reason is as follows: Since the clamping block 54 generates a reaction force with an equivalent clamping force due to the article, the rack 531 is pressed against the tooth 561, so that the tooth 561 is not easy to separate the rack by the swinging manner. 531, the user can not directly operate the release button 56 to relax, so it is necessary to first force the pressing of the pressing handle 55, the first tooth 561 is not stuck at the rack 531, however, the pressing handle 55 is originally under full force compression At the position of the article, the pressure handle 55 needs to exert a greater force than the original clamping force, so that the pressure handle 55 can be further depressed, so that the release operation is too laborious.
