BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The invention is in the field of folding furniture, in particular the invention is to a folding table, which can realize a folding collection of upper and lower parts and can be used to support an umbrella and assemble into an umbrella folding table for outdoor use. 
     Technical Background 
     Patent No. 201710831683.9 shows a folding table, comprising an upper support part and a lower support part, in which the upper support part is inserted into the guide pipe of the lower support part by means of a shaft rod to form a docking position with the lower support part. The lower end face of the upper main disc collides with the upper end face of the lower main disc to form a bearing support. The supporting device has the characteristics of strong versatility, wide application and stable support, but it also has the shortcomings of high locality, the fact that the upper and lower main plates of the upper and lower support parts must conflict with each other. Moreover, the flexible desktop supported by the device has no tension design, and it is easy to collapse after shelving items on it, which affects the use of the device. 
     For folding tables, the main consideration is to fold compactly and make it easier to store and carry, especially for outdoor use. For this reason, the combination of an umbrella and table is also the industry&#39;s most considered option. such as: 
     The patent application No. 200720032755.5, shows a solar multi-functional sunshade for automobile and traveling. It includes an umbrella frame, the umbrella textile wrapped on the frame and the frame sliding seat supporting the frame. The sliding seat is equipped with a central axis, and the lower end of the central axis is connected with an interface connector, and the lower end of the interface connector is equipped with a support device. The support device includes an upper support rod which is connected with a lower support rod by the interface, and the lower end of the lower support rod is attached to the base by a hinge. A removable table is installed on the lower support rod, which includes a table supported by the movable support, one end of the movable support is attached to the lower support rod of the umbrella by hinge. The other end is attached to the sliding sleeve of the support with positioning device, and the sliding sleeve of the support is installed on the lower support rod of the umbrella handle. The design combines the movable table with the sunshade, but the structure is too messy and the assembly is too complicated. 
     Another example is patent application No. 201720769472.2, which shows a multi-functional sunshade which includes the umbrella bar, the umbrella frame installed on the bar and the textile attached on the outer surface of umbrella frame. A connecting seat is fixed on the bar, and at least two pivotal grooves are installed on the connecting seat. The bottom of each pivotal groove is provided with a stopper, and each pivotal groove is matched by a supporting rod to which a table surface is attached. Structurally, it fulfills the table function, but the support rod which bears the table is directly attached to the connecting seat, which appears flimsy and it is difficult to tighten the table, and also limits the space of the table surface. 
     All the existing technologies have shortcomings in the design of a folding table or umbrella with table. How to fulfill the function of folding table, how to assemble and disassemble conveniently, how to be compact and be able to support the umbrella at the same time are some of the objectives of the current research.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) 
     Referring to  FIGS. 1, 2 and 3 , a folding table with an umbrella is shown. The folding table part comprises a desktop fabric  1 , an upper support  2  and a lower support  3 . 
     The upper support  2  includes an upper main disc  21 , the upper auxiliary disc  22 , the upper support rod  23 , the upper connecting rod  24  and the shaft rod  25 . One end of the plural upper support rod  23  is articulated on the upper main disc  21  and the other end is used to support the desktop fabric  1 . Specifically, four to eight upper support rods  23  are radially distributed on the upper main disc  21 , and the upper support rod  23  is planar to support the desktop fabric  1 . This example has six support rods  23 . It can support a six-sided desktop. The larger the number of supporting rods, the better the tautness of the desktop. The corresponding number of upper connecting rods  24  are articulated at one end on the upper support rod  23  and at the other end on the upper and auxiliary discs  22 . 
     The axle bar  25  is locked onto the upper and auxiliary discs  22  and penetrates through the reserved holes of the upper main disc  21  downwardly to form a solid relationship. A locking sleeve  4  is arranged between the upper main disc  21  and the axle bar  25 . With the help of the locking sleeve  4 , the upper main disc  21  is locked in the design position of the axle bar  25 , and the desktop fabric  1  can be tightened. That is to say, the upper main disc  21  slides upwardly along the shaft bar  25 , pushes the upper support bar  23  apart, and extends the upper main disc  21  relatively downward when the shaft rod  25  is opened. 
     The lower support part  3  includes the lower main disc  31 , the lower auxiliary disc  32 , the lower support rod  33 , the lower connecting rod  34  and the guide pipe  35 . The end of the plural lower support rod  33  is articulated on the lower main disc  31 , and the corresponding number of lower connecting rods  34  is articulated on the lower support rod  33  at one end and on the lower auxiliary disc  32  at the other end; specifically, four to six lower support rods  33  are radially distributed on the lower main disc  31 , and the end lock is inherently grounded. The plastic part  331  is used to increase the contact surface with the ground. In this example, the lower support rod  33  is four in number, which can balance the support to the desktop and remain stable on the ground. 
     The guide pipe  35  is locked in the through hole  311  of the lower main disc and passes through the reserved hole of the lower auxiliary disc, that is to say, it keeps the upper end of the guide pipe  35  connected with the through hole  311  and provides for the insertion of the shaft rod  25 . When the lower support rod  33  is opened in place, the guide pipe  35  still extends out of the lower auxiliary disc  32  to form the direction of restraint and folding. Furthermore, the guide pipe  35  has a closed bottom or a pin horizontally arranged to support the inserted shaft rod  25  lower end. 
     The upper support part  2  and the lower support part  3  are separate structures. The upper support part  2  is opened and folded independently of the lower part. The upper support part  2  is inserted into the guide tube  35  of the lower support part through the shaft rod  25  to form a positioning relationship between them. No additional positioning is needed. The upper support part  2  cannot rotate around the guide tube  35  to increase the usefulness. At the same time, the design height of the desktop is more flexible. Only the shaft rod  25  or the lower support part  35  needs to be changed. The length of the guide pipe  35  is enough. 
     In this design, the relative area of the desktop is large, and a supporting disc  26  is also arranged on the upper and auxiliary disc  22 . The upper end face of the supporting disc  26  is higher than the plane of the tightened desktop fabric  1  for less than 3 cm which forms a support beneath the center of the desktop fabric  1  to prevent any collapse. 
     Further, the axle  25  fixed on the upper auxiliary disc  22  is extended upwardly. An umbrella  5  is inserted at the upper end of the axle rod, and a manual clamp  6  for fastening is arranged at the insertion part of the umbrella rod  51  and the axle rod  25 . Manual clamp  6  is locked at the end of umbrella rod  51 . The upper end of shaft rod  25  is inserted in the manual clamp  6 . Alternatively, the manual clamp  6  can be locked at one side of shaft rod. The upper end of the shaft rod  25  is fixed with a core shaft section  251 . The core shaft section  251  is inserted into the umbrella rod  51  to form a staggered connection with the manual clamp  6 , which reduces the transverse force of the manual clamp  6  where thereby the connecting part can withstand greater wind force as shown in  FIGS. 2 and 5 . 
     Referring now to  FIG. 4 , the manual clamp  6  includes sleeve  61  and handle  62 . One end of sleeve  61  is divided into a pair of shrinkage pages  612  by T-shaped shrinkage joint  611 . Each of which is provided with an axle base  613 , while the axle base  613  is provided with a symmetrical notch  614  on the far side. A pair of axle ears  621  corresponding to the axle base  613  are opposite to each other, and a slope  622  is symmetrically arranged. The handle  62  is positioned on the axle base  613  through the pin axis  63 . Swing handle  62 , the slope  622  can drive the sleeve shrinkage page  612  to clamp the shaft rod, with the notch  614  serves as the boundary between locking and release. 
     Referring to  FIG. 2 , the umbrella  5  is a folding umbrella with an umbrella rod  51 , plural skeleton  52 , driving sleeve  53  and umbrella surface  54 . The umbrella skeleton  52  is articulated between the top of umbrella pole  51  and driving sleeve  53 , sliding up and down along the umbrella rod by driving sleeve  53 , to drive the skeleton  52  open and close. A locking sleeve  4  is arranged between driving sleeve  53  and umbrella rod  51 , and the skeleton  52  is locked in the opening position which holds the umbrella open. The umbrella surface  54  of this design is large. The umbrella rod  51  has an inherent connection seat  55  at the top lock. The plural parachute skeleton  52  is evenly distributed on the circumference of the connection seat  55 , that is, one end of the first member  521  is articulated on the connection seat  55 . 
     Referring now to  FIG. 5 , the locking sleeve  4  mentioned above includes a nut sleeve  41  and a hollow hand-adjusting bolt  42 , which is provided with a ring groove  421  between the knob and the thread section. With the help of the ring groove  421 , the locking sleeve  4  is rotated and positioned on the upper main disc  21  and the driving sleeve  53 , and can follow the upper main disc  21  or the driving sleeve  53  to slide up and down; while the nut sleeve  41  corresponds to the design position of the shaft  25  and umbrella rod  51 . In operation, as long as the upper main disc  21  or drive sleeve  53  is slid in place, the adjusting hand-adjusting bolt  42  can be screwed into the corresponding nut sleeve  41  to form a reliable connection. Through an extended connection, the tabletop fabric  1  and umbrella surface  54  can be tightened, and the positioning is more reliable. In this illustration, the lock set  4  is used in the upper support  2  and the same can be used in the sunshade. 
     The present folding table with umbrella is more suitable for outdoor use. If there is no need for shelter, the installation proceeds without the umbrella, and it does not affect the normal use of folding table. Because sunshade needs a larger area of shade and the height in use, the folded height of the umbrella is still the highest among the three parts. According to the design standard, the height of the supporting design shaft rod  25  should be equivalent, as shown in  FIG. 3 . As for the lower support part  3 , the design considers the stability of the ground support and generally requires a landing with four feet to meet the needs of the stable support while minimizing the obstruction to ground movement. Moreover, the desktop supported by the upper support part  2  can not only form ground obstacles by opening the lower support part  3 , but also achieve shade over the desktop which transforms into useful space. The overall coordination of this three-section design streamlines disassembly and assembly operation, with the opening and folding action being simple and consistent. The height after folding is less than half of the full height, which greatly improves its utility. It also reduces the space requirement for collection and transportation.
