     DETAILED DESCRIPTION 
     The invention is illustrated in accordance with figures. The figures as simplified diagrams demonstrate the basic structures of the apparatus of embodiments of the invention. Thus, the invention is not limited to the figures. 
     Referring to  FIGS. 1-4 , a light and convenient pneumatic device for preparing tea brick includes a worktable  1 , a supporting device  2  arranged at the bottom of the worktable  1 , a punching device  3  arranged on the top of the supporting device  2  and a limiting device  4  arranged on the top of the worktable  1 . The bottom of the worktable  1  is provided with a rectangular receiving cavity  1   a  with an opening upward. The supporting device  2  includes a supporting component  2   a  fixedly disposed at the bottom of the worktable  1 . The punching device  3  includes a power component  3   a,  a punching component  3   b  and a waterproof component  3   c.  The power component  3   a  is fixedly disposed at the top of the supporting component  2   a.  The punching component  3   b  is fixedly disposed on an output end of the power component  3   a.  The waterproof component  3   c  is sleeved on an output end of the power component  3   a.  The punching component  3   b  includes a punching block  3   d,  and the punching block  3   d  is disposed in the rectangular receiving cavity  1   a.  The bottom of the rectangular receiving cavity  1   a  is provided with a protrusion  1   b  for receiving the punching block  3   d.  The limiting device  4  includes a limiting component  4   a,  and the limiting component  4   a  includes a limiting block  4   b.  The limiting block  4   b  is arranged at the top of the rectangular receiving cavity  1   a.  The punching block  3   d,  the rectangular receiving cavity  1   a  and the limiting block  4   b  constitute a working compartment for preparing the tea brick. The rectangular receiving cavity  1   a  in the worktable  1  is a place where the tea brick is molded. On one hand, the supporting component  2   a  supports the worktable  1 . On other hand, the supporting component  2   a  supports power component  3   a.  The power component  3   a  provides power in the vertical direction so that the punching block  3   d  can move upward and downward in the rectangular receiving cavity  1   a.  The limiting block  4   b  is used to restrict the position where the punching block  3   d  moves upward. During the upward punching of the punching block  3   d,  the steamed tea leaves are extruded. The waterproof component  3   c  is used for receiving the water during extrusion. 
     The power component  3   a  includes a first cylinder  3   e  and a cylinder shaft  3   f  disposed at the top of the first cylinder  3   e.  The first cylinder  3   e  is fixedly disposed at the top of the supporting component  2   a,  and the cylinder shaft  3   f  is disposed at the top of the first cylinder  3   e.  The punching block  3   d  is fixedly arranged on the top of the cylinder shaft  3   f.  The first cylinder  3   e  is opened. The first cylinder  3   e  drives the cylinder shaft  3   f  to move upward and meantime drives the punching block  3   d  to move upward. 
     The waterproof component  3   c  includes a water receiving tray  3   g  which is sleeved on the cylinder shaft  3   f  and located at the top of the first cylinder  3   e.  When the punching block  3   d  moves upward to extrude, the water in the streamed tea leaves is squeezed and the water receiving tray  3   g  is used to receive the water. 
     The supporting component  2   a  includes four supporting legs  2   b  and a supporting plate  2   c  for fixing the first cylinder  3   e.  The four supporting legs  2   b  are distributed in a rectangular shape at the bottom of the worktable  1 , and the supporting plate  2   c  is horizontally and fixedly disposed at four supporting legs  2   b.  The four supporting legs  2   b  are mainly used to support the worktable  1 . The supporting place  2   c  is mainly used to support and fix the first cylinder  3   e.    
     The limiting component  4   a  further includes a limiting cover  4   c.  The limiting cover  4   c  is disposed at the top of the worktable  1 , and one end of the limiting cover  4   c  is hinged with the worktable  1 . One end of the limiting cover  4   c  away from the hinge is provided with a plurality of buckles  4   d.  The side wall of the worktable  1  is provided with a plurality of blocks  4   e.  Each of the buckles  4   d  is engaged with each of the blocks  4   e.  The appropriate amount of streamed tea leaves is placed in the rectangular receiving cavity  1   a,  and the limiting block  4   b  is closed. The limiting block  4   c  is then rotated to be closed and the buckle  4   d  is buckled. 
     The limiting block  4   b  and the punching block  3   d  are rectangular plate-like structures of the same size and have the same cross-sectional size of the rectangular receiving cavity  1   a.  The punching block  3   d,  the limiting block  3   d  and the rectangular receiving cavity  1   a  have the same cross section size, and the tea is extruded into tea bricks with rectangular shape during the extrusion. 
     The bottom of the limiting block  4   b  is provided with stripes for punching and molding. The top of the punching block  3   d  is provided with stripes for punching and molding. When the surface of the tea bricks needs molding to increase stripes, it can be achieved by changing the strips on the surface of the limiting block  4   b  and the punching block  3   d.    
     The working principle is as follows. First, the limiting cover  4   c  is opened, and the limiting block  4   b  is taken out. The streamed tea leaves with an appropriate amount are placed in the rectangular receiving cavity  1   a.  The limiting block  4   b  is covered, and the limiting cover  4   c  is rotated and covered. The buckle  4   d  is buckled. The first cylinder  3   e  is opened, and the first cylinder  3   e  drives the cylinder shaft  3   f  to move upward and simultaneously drives the punching block  3   d  to move upward. Because the limiting block  4   b  is in a stationary state, the punching block  3   d  is moved upward and squeezed, and the water in the tea leaves is squeezed. The water receiving tray  3   g  is used for receiving the water to avoid contamination. When the extrusion and molding is completed, the first cylinder  3   e  is closed, and the limiting cover  4   c  is opened. At this time, the tea brick is made, but it is not easy to take out, and the first cylinder  3   e  can be opened again. The first cylinder  3   e  ejects the limiting block  4   b  and simultaneously ejects the tea bricks, at which time the substantially formed tea bricks are taken out. 
     The exemplary embodiments of the present invention are thus fully described. Although the description referred to particular embodiments, it will be clear to one skilled in the art that the present invention may be practiced with variations of these specific details. Hence this invention should not be construed as limited to the embodiments set forth herein.
