[0021] The utility model is implemented as follows Figures 1 to 6As shown in the figure, a portable support frame includes a support plate 1, and the support plate 1 is selected to have a flat internal hollow or non-hollow structure. For example, the support plate 1 is set to a cylindrical structure, and then connecting pieces are correspondingly set at its lower end and upper end to connect the base 2 and the placement seat 3. The opposite ends of the support plate 1 are correspondingly limited and pivotally connected with the base 2 and the placement seat 3 that can be flipped relative to the support plate 1. The lower end of the support plate 1 is limited and pivotally connected to the base 2, and the upper end of the support plate 1 is limited and pivotally connected to the placement seat 3. When unfolded, the base 2 and the placement seat 3 are flipped in different directions, that is, the base 2 is rotated in the counterclockwise direction. The base 2 is flipped up and down, and the placement seat 3 is flipped up and down in a clockwise direction. After flipping into place, the base 2 and the placement seat 3 are at the lower end and the upper end of the same side of the support plate 1. The placement seat 3 can be used to place corresponding electronic devices so that the support frame can be used as a reading rack or a bracket. The base 2 is provided with a base notch 22 in the middle of the edge of one end thereof, and the support plate 1 is limited and pivotally connected with the base 2 at the base notch 22, so that the support plate 1 and the base 2 are kept in a flush state at the edge, and the support plate 1 does not protrude from the base 2; the base 2 is provided with a base for storing the placement seat 3 and the support The storage slot 20 of the support plate 1 is arranged on the bottom surface of the base 1. The storage slot 20 is formed by an extension arm of a U-shaped structure arranged or extended at the bottom edge of the base 1 and placed sideways. The bottom edge of the U-shaped structure of the extension arm is a flat bottom structure, which is located at the rear edge of the base 2, and the opening is located at the front edge of the base 2. The thickness of the extension arm gradually decreases from the back to the front, so that the base 2 will be tilted forward at a certain angle when placed on the desktop. When the support frame is used as a reading frame, the electronic equipment placed on it will also be tilted forward at a certain angle, which is convenient At this time, a notch is set on the base 2 corresponding to the position of the bottom edge of the extension arm, which penetrates the base 2 and the extension arm, and then the support plate 1 is pivoted with the base 2 in the notch, so that the support plate 1 does not protrude from the rear edge of the base 2; the placement seat 3 is movably provided with a baffle 4 that can be hidden in the placement seat 3 at one end away from the support plate 1, and the placement seat 3 is pivoted with the support plate 1 at the rear end, and the baffle 4 is set at its front end. At this time, the baffle 4 can be movable relative to the placement seat 3, and the baffle 4 can be pulled out of the placement seat 3 when needed, and pushed back into the placement seat 3 when not needed. With such a structure, when stored, the baffle 4 is hidden in the placement seat 3, and then the support plate 1 and the placement seat 3 are turned over and stored in the storage groove 20, so that no parts protrude from the surface of the base 2, so that the folded bracket becomes very small, and it is not easy to be squeezed and collided and damaged during carrying, which is convenient to carry.Furthermore, the base 2 is provided with a base through hole 21 that can be used for holding when the placement seat 3 and the support plate 1 are stored in the storage groove 20. That is to say, after the placement seat 3 and the support plate 1 are stored in the storage groove 20, the placement seat 3 and the support plate 1 will not block the base through hole 21, and the support frame can be held and lifted by using the base through hole 21; when the base 2 and the support plate 1 are pivotally connected at the rear end of the base 2, one situation is that when the placement seat 3 and the support plate 1 are stored in the storage groove 20, the placement seat 3 and the support plate 1 do not cover the bottom of the front end of the storage groove 20. At this time, the base through hole 21 is provided on the bottom of the front end of the storage groove 20; another situation is that when the placement seat 3 and the support plate 1 are stored in the storage groove 20, the placement seat 3 and the support plate 1 do not cover the bottom of the front end of the storage groove 20. The seat 3 and the support plate 1 completely cover the bottom of the storage groove 20. At this time, a base through hole 21 is set at the bottom of the front end of the storage groove 20, and a support plate through hole 10 is also set on the support plate 1. The support plate through hole 10 is set at the end of the support plate 1 away from the base 2. The base through hole 21 and the support plate through hole 10 are coaxial when the seat 3 and the support plate 1 are stored in the storage groove 20, which is convenient for holding and lifting the support frame; in both cases, the base through hole 21 is set on the side of the base 2 away from the pivot position between the base 2 and the support plate 1, that is, the front end of the base 2. When it is convenient to hold and lift, it will not affect the pivot structure between the support plate 1 and the base 2. The base through hole 21 facilitates the holding and lifting of the bracket, which is more conducive to use.

At the same time, an annular damping member that generates damping by friction with the lower end through hole is sleeved on the two ends of the rotating shaft corresponding to the lower end through hole. The damping member can be formed by two semicircular ring components sleeved on the rotating shaft, and the lower end through hole constitutes the damping through hole, and the rotating shaft and the damping member sleeved thereon constitute the damping shaft; Figure 4 As shown in the figure, the support plate 1 and the placement seat 3 are pivotally connected by another damping structure consisting of a damping shaft 7 and a damping through hole 70. This structure can adopt the same damping structure as the pivotal connection between the support plate 1 and the base. When the placement seat 3 is composed of two support arms, an upper through hole penetrating the left and right side walls of the support plate 1 is also provided at the top of the support plate 1. The upper through hole constitutes the damping through hole 70 in the damping structure. A rotating shaft 71 is inserted into the upper through hole and passes through it.
