[0034] As another further provided embodiment of the utility model, circular plate 21 is fixedly installed on mobile seat 2 and is inserted with rotary table 3.

[0035] Specifically, convex-shaped shaft rod is integrally formed on lower end surface of rotary table 3, and circular groove is opened on upper end surface of circular plate 21 for embedding and rotating of shaft rod, so that rotary table 3 and mobile seat 2 are kept connected.

[0036] Rotary table 3 is stably rotated on mobile seat 2, which is convenient for rotary table 3 to rotate according to placing position of metal plate, and the purpose is to facilitate operator polishing.

[0037] As another further provided embodiment of the utility model, clamping hole 31 is arranged on rotary table 3 for sliding of stand column 4, and worm sleeve 51 is rotatably arranged in clamping hole 31.

[0038] Residual worm wheel head 41 is arranged on end portion of stand column 4 and is engaged with worm sleeve 51.

[0039] Specifically, residual worm wheel head 41 is kept engaged with worm sleeve 51, and residual worm wheel head 41 is part of complete worm wheel.

[0040] Residual worm wheel head 41 is driven to rotate in clamping hole 31 by worm sleeve 51, so as to adjust inclination angle of stand column 4, and then inclination angle of metal plate is adjusted.

[0041] As a further provided embodiment of the utility model, rotating shaft 5 is further included for fixing worm sleeve 51, and handle 6 is slidably sleeved on rotating shaft 5.

[0042] Specifically, worm sleeve 51 is assembled by inner diameter extrusion on side wall inclined surface or step of rotating shaft 5.

[0043] Rotating handle 6 can drive worm sleeve 51 to rotate, which is convenient for driven swinging and locking of stand column 4, and under self-locking action, the use amount of parts is reduced, and the safety and service life are reduced due to damage of motor with self-locking after core is pressed.

[0044] As further provided by the utility model, the handle 6 is fixedly installed with a plug rod 61, and the circular plate 21 is provided with a plurality of lock holes 22 arranged in a circle and matched with the plug rod 61.

[0045] By adjusting the position of the handle 6, the position between the rotating table 3 and the circular plate 21 can be changed, and the rotating table 3 can be fixed at the specified position after rotation, so that the locking function of the rotating table 3 is realized, and the stability of the metal plate after placement is improved.

[0048] By pulling the handle 6 to the position of the protrusions 52 to be coupled, the unlocked circular plate 21 does not interfere with the rotation of the rotating shaft 5 driven by the handle 6, and then after the decoupling of the protrusions 52, the rotating table 3 is locked again, and no metal plate is added in the process, so there is no influence of other factors.

[0049] As further provided by the utility model, the base 1 is provided with a motor for driving the screw rod 12 to rotate.

[0050] Specifically, the motor is powered by a 220V power supply, and the motor and its wiring mode, self-locking mode are all prior art, which will not be described here.

[0051] The motor is convenient for driving the screw rod 12 to rotate, and is also convenient for stopping the movement of the moving seat 2, and the moving seat 2 is located in the square groove 11, so it will not cause the screw rod 12 to be crushed by the weight.

[0052] As further provided by the utility model, the handle 6 is fixedly installed with a pull spring located outside the rotating shaft 5.

[0053] Specifically, the pull spring is rotatably connected to the side wall of the rotating table 3.

[0054] After the rotating shaft 5 is rotated by any angle, the handle 6 is released and the plug rod 61 is returned to vertical under the rotatable action of the pull spring, i.e. the plug rod 61 is aligned with the direction of the lock hole 22, so that the change of the arbitrary inclination angle (switching between 20°-160° with respect to the horizontal plane) of the stand 4 will not affect the locking of the rotating table 3.

[0055] As further provided by the utility model, the stand 4 is specifically a steel alloy column.

[0056] By using steel alloy columns to increase rigidity and prevent the metal plate from bending under gravity when tilted and fallen, high-strength load-bearing capacity is achieved, and the stability of the metal plate placement and clamping is improved.

[0057] Working principle: The metal plate is vertically clamped by multiple clamps 7 on the two columns 4, so that the end face of the metal plate faces the operator. Rotating the worm gear 51 can tilt the columns 4 at any angle and lower the height of the metal plate. When the columns 4 are staggered by the transmission of the screw 12, the turntable 3 is rotated to clamp the metal plate, changing the facing angle of the metal plate and the operator. This allows the grinding position of the metal plate to be changed according to the actual site. The distance between the two turntables 3 is adjustable to accommodate metal plates of different widths, improving the adaptability. The metal plate can also be tilted after the facing angle is changed, so that the height and position can be adapted on site.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
