[0043] like Figure 6 , Figure 7 , Figure 8 and Figure 11 As shown, the table body 3 includes a table 31 and a frame 32. The table 31 and the frame 32 cooperate with each other and are fixedly connected by screws. The frame 32 is equipped with a pivot locking component 4. The frame 32 is equipped with limit stops according to the pivot locking component 4 to match the position of the pivot locking component 4.

[0044] like Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the pivot locking assembly 4 includes a button lever 41, a transmission rod 43, a first brake spring 42, a support leg 44, a push bracket 45, a second brake spring 46, an inclined slide block 47, and a bushing 48. The button lever 41 is arranged correspondingly to the mounting groove of the frame 32. The first brake spring 42 is connected to the button lever 41 to provide key travel and button return force. One end of the button lever 41 is connected to the transmission rod 43, and the other end of the transmission rod 43 is connected to the support leg 44. The inclined slide block 47 has 45° U-shaped grooves on both sides, and the inclined slide block 47 is connected to the bushing 48. A groove is provided, and a second braking spring 46 is provided between the groove on the bushing 48 and the groove on the inclined slide block 47. The support leg 44 and the inclined slide block 47 are linked to form a transmission function. The inclined slide block 47 and the reserved groove on the bushing 48 correspond one-to-one. Furthermore, the inclined slide block 47 and the bushing 48 form a single degree of freedom linkage through the second braking spring 46. The cylindrical pin ends on both sides of the support 45 are linked with the inclined slide block 47. The cylindrical pin ends on both sides of the support 45 are linked with the 45° U-shaped grooves on both sides of the inclined slide block 47 to form a sliding linkage. The flat end of the support 45 is linked with the flat end of the support leg 44.

[0045] like Figure 7 , Figure 11 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, the cylindrical pin end of the inclined top slider 47 is inserted into the limiting through hole of the locking sheet metal 21 in the support assembly 2. The cylindrical pin end of the inclined top slider 47 can slide back and forth in the limiting through hole and rotate around the central axis of the cylindrical pin. The cylindrical pin of the inclined top slider 47 can also pass through the limiting through hole of the locking sheet metal 21 and enter the locking through hole in the limiting sheet metal 22. Furthermore, the cylindrical pin of the inclined top slider 47 can slide and rotate within the locking through hole of the limiting sheet metal 22.

[0046] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, the cylindrical pin at the end of the frame 32 is inserted into the rotation limit U-shaped groove of the locking sheet metal 21, and the frame 32 and the table body 3 work together to form a folding and swinging motion around the limit through hole of the locking sheet metal 21.
