The function of the lower gasket and the upper gasket is to prevent the device from damaging the surface of the workpiece to be processed when tightening the workpiece, and improve the processing quality of the device. At the same time, there is a spring on the fixed block. The function of the spring layer is to buffer the vibration generated during the processing of the workpiece, thereby further improving the processing quality of the device. In addition, the movable block is divided into an upper block and a lower block, and the lower block is fixed on the upper block by clamping. Below, there is a ball between the upper block and the lower block. The function of the ball is to make the relative movement between the upper block and the lower block. The rolling friction is replaced by sliding friction, which greatly reduces the screw rotation. The resistance suffered facilitates the tightening of the workpiece to be processed.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, in the embodiment of the utility model, a kind of fixture, comprises base 1, fixed block 2, spring layer 3, lower gasket 4, upper gasket 5, movable block 6, reinforcing rod 7, support rod 8 , fixed plate 9, handle 10, screw rod 11, fixed column 12, ball 13, upper block body 14 and lower block body 15, described base 1 upper end is provided with fixed column 12, and fixed column 12 upper end is provided with support bar 8, supports The upper end of the rod 8 is provided with a fixed plate 9, and the fixed plate 9 and the support rod 8 are connected and fixed by welding. , between the screw rod 11 and the fixed plate 9 is threaded connection, the upper end of the screw rod 11 is provided with a handle 10, the lower end of the screw rod 11 is provided with a movable block 6, the lower end of the movable block 6 is provided with an upper gasket 5, and the base below the movable block 6 1 is provided with a fixed block 2, and the upper end of the fixed block 2 is provided with a lower gasket 4, which is made of rubber material.
