[0023] See also Figure 1-6The present embodiment is a bench vise that is easy to use, and is composed of structural components such as a clamping mechanism 1, a fixed seat 2, and a lifting seat 10. The clamping mechanism 1 is used to clamp the workpiece that needs to be polished. The clamping mechanism 1 is fixedly installed on the top of the lifting seat 10. At least three sets of lifting mechanisms are arranged inside the fixed seat 2. The lifting mechanisms are used to assist the lifting seat 10 in lifting. The lifting mechanisms include a screw sleeve 3, a bearing 4, a threaded rod 5 and a movable hole 7. Four through-type movable holes 7 are arranged at the four corners of the top surface of the fixed seat 2. The bearing 4 is installed inside the fixed seat 2 and is located between the two movable holes 7. The axis of the bearing 4 is symmetrical with the axis of the movable hole 7. The fixed seat 2 is provided with a screw sleeve 3, a bearing 4, a threaded rod 5 and a movable hole 7. There is a screw sleeve 3, the upper end of the screw sleeve 3 is exposed outside the bearing 4, and a pinion 6 is fixed on the top surface of the screw sleeve 3. The inside of the screw sleeve 3 is hollow, and one end of the pinion 6 is connected to a transmission gear 8. The transmission gear 8 is mainly used to drive the four pinions 6 to rotate at the same time. A motor 9 is fixedly installed at the bottom of the fixed seat 2, and the top of the output end of the motor 9 is fixedly connected to the transmission gear 8 to achieve a transmission effect. The threaded rod 5 penetrates the movable hole 7 from the top and then penetrates the screw sleeve 3 and the bearing 4 below in turn. The bearing 4 assists the rotation of the screw sleeve 3. The thread inside the screw sleeve 3 matches the thread on the surface of the threaded rod 5. When the threaded rod 5 rotates in the screw sleeve 3, it has a lifting effect.

[0024] Furthermore, the lifting mechanism is provided with four groups and is arranged in a rectangular shape below the lifting seat 10, which improves stability. At the same time, all the pinions are meshed with the transmission gears, thereby achieving the effect of transmitting the four lifting mechanisms.

[0025] Furthermore, the threaded rod 5 is made of high-strength steel, which improves the strength of the threaded rod 5 , thereby improving its durability and the firmness of supporting the lifting seat 10 .

[0026] Furthermore, a fixing block 11 is installed on the side wall of the fixing seat 2, and the fixing block 11 is fixed on the table surface by fastening bolts.

[0027] Furthermore, fixing blocks 11 are provided at the four corners of the fixing seat 2 to improve stability and firmness. At the same time, the fixing blocks 11 are made of high-strength steel to improve the strength of the fixing blocks 11.

[0028] The working principle of this embodiment is as follows: when in use, first align the movable hole 7 at the bottom of the base with the reserved hole on the workbench to be installed, and then install and fix it through the fixing block 11. When adjusting the clamping structure, the motor 9 is electrically connected to the factory. When the motor 9 rotates forward, it drives the transmission gear 8 to rotate, and the transmission gear 8 thereby drives the four pinion gears 6 to rotate, and the screw sleeve 3 is driven to rotate in the bearing 4 through the pinion gear 6. When the screw sleeve 3 rotates, its internal thread matches the thread of the threaded rod 5, thereby converting the rotational motion into an ascending motion of the threaded rod 5 inside it. When the threaded rod 5 rises in the movable hole 7, the lifting seat 10 on the top is driven to rise and fall to achieve the effect of raising the clamping mechanism 1. The reserved hole on the workbench is used to install the bench vise to provide a moving space for the threaded rod 5, which greatly improves the convenience of using the bench vise and the user experience of the operator. Conversely, the descending effect can be achieved when the motor 9 is reversed.
