[0007] To achieve the above purpose, the utility model provides the following technical scheme: A push frame capable of multi-angle adjustment, including a bottom plate and a long pin. The upper surface of the bottom plate is bolted with a support plate, and the support plates are symmetrically distributed about the center of the bottom plate. The upper surface of the support plate is bolted with a connecting plate, and a scale mark is engraved on the upper surface of the connecting plate.

[0008] The long pin is rotatably arranged inside the connecting plate, a first insertion plate is fixedly connected to the surface of the long pin, and a second insertion plate is fixedly connected to the lower surface of the connecting plate.

[0009] It further includes:

[0011] Movable plate, the movable plate is slidably arranged inside the support plate, and a fixed shaft is fixedly connected to the surface of the movable plate, and a push rod is sleeved and connected to the surface of the fixed shaft;

[0012] Fixed block, the fixed block is fixedly connected to the inner wall of the first insertion plate;

[0013] Drive shaft, the drive shaft is rotatably arranged inside the connecting plate, and the upper surface of the connecting plate is convex.

[0014] Preferably, clamping pieces are fixedly connected to the surface of the threaded rod, a connecting rod is fixedly connected to the surface of the movable plate, and the clamping pieces are symmetrically distributed about the center of the connecting rod.

[0015] Preferably, columns are fixedly connected to the inner wall of the support plate, and the columns penetrate through the inside of the movable plate.

[0016] Preferably, an inner shaft is fixedly connected to the inside of the fixed block, and the other side of the push rod is sleeved and connected to the surface of the inner shaft.

[0020] Compared with the prior art, the beneficial effects of the present utility model are: the push frame with multi-angle adjustment adopts a new structural design, and the specific content is as follows:

[0021] During the use of the push frame with multi-angle adjustment, when the angle needs to be adjusted, the threaded rod can be rotated. At this time, the threaded rod descends inside the inner rod, and then the clamping pieces drive the connecting rod and the movable plate to descend. At this time, the push rod pushes the first insertion plate, so that the first insertion plates on both left and right sides are unfolded, and finally the angle adjustment function is achieved;

[0022] Furthermore, during the movement of the movable plate, the columns enable the movable plate to move only in the vertical direction, ensuring stability;

[0023] When the movable plate of the push frame that can be adjusted at multiple angles descends, the movable plate unfolds through the traction rope protective film. Then, the protective film will gradually cover the scale markings. For the scale markings that are not covered, the value closest to the inner position of the connecting plate is the angle value at which the first plug board unfolds. This facilitates the operator's precise control of the angle and improves flexibility.

[0024] Furthermore, the movable plate is in a vertically moving state, so that the pulling force of the traction rope can always be maximized, which is convenient for the operation of the traction rope.

[0025] (3) When the transmission shaft of the push frame that can be adjusted at multiple angles rotates, the transmission shaft will stretch the torsion spring. When the rotary threaded rod rotates, the movable plate rises. At this time, the first plug board rotates. At the same time, the transmission shaft loses the pulling force of the traction rope. Then, the transmission shaft rotates under the action of the torsion spring. When the transmission shaft rotates, it will wind up the protective film, which is convenient for subsequent use.

Detailed Description of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0034] Embodiment 1: By providing the movable plate 11 and the push rod 16, the first plug board 3 can be unfolded and the angle can be quickly adjusted, as Figures 1-4 shown:

[0035] A push frame with multi-angle adjustment includes a bottom plate 1 and a long pin 7. The upper surface of the bottom plate 1 is bolted with a support plate 2, and the support plates 2 are symmetrically distributed about the center of the bottom plate 1. Moreover, the upper surface of the support plate 2 is bolted with a connecting plate 4, and a scale mark 6 is engraved on the upper surface of the connecting plate 4;

[0036] The long pin 7 is rotatably arranged inside the connecting plate 4, and a first plug board 3 is fixedly connected to the surface of the long pin 7. Moreover, a second plug board 5 is fixedly connected to the lower surface of the connecting plate 4;

[0037] It further includes:

[0038] An inner rod 8, the inner rod 8 is fixedly connected to the inner wall of the support plate 2, and a threaded rod 9 is rotatably arranged inside the inner rod 8. Moreover, the upper end of the threaded rod 9 is spherical. A movable plate 11, the movable plate 11 is slidably arranged inside the support plate 2, and a fixed shaft 13 is fixedly connected to the surface of the movable plate 11. Moreover, a push rod 16 is sleeved and connected to the surface of the fixed shaft 13;

[0039] A fixed block 14, the fixed block 14 is fixedly connected to the inner wall of the first plug board 3. A transmission shaft 19, the transmission shaft 19 is rotatably arranged inside the connecting plate 4, and the upper surface of the connecting plate 4 is convex.

[0040] A clip 10 is fixedly connected to the surface of the threaded rod 9. A connecting rod 12 is fixedly connected to the surface of the movable plate 11. The clips 10 are symmetrically distributed about the center of the connecting rod 12. A column 17 is fixedly connected to the inner wall of the support plate 2, and the column 17 penetrates through the inside of the movable plate 11. An inner shaft 15 is fixedly connected to the inside of the fixed block 14, and the other side of the push rod 16 is sleeved and connected to the surface of the inner shaft 15.

[0041] During use, when the angle needs to be adjusted, the threaded rod 9 can be rotated. At this time, the threaded rod 9 descends inside the inner rod 8, and then the clamping piece 10 drives the connecting rod 12 and the movable plate 11 to descend. At this time, the fixed shaft 13 pushes the inner shaft 15 and the fixed block 14 through the push rod 16. At this time, under the action of the thrust, the first insertion plate 3 drives the long pin 7 to rotate inside the connecting plate 4. Finally, the first insertion plates 3 on both the left and right sides unfold, ultimately playing the role of adjusting the angle. During the movement of the movable plate 11, the column 17 enables the movable plate 11 to move only in the vertical direction, ensuring stability. After the first insertion plate 3 unfolds, the second insertion plate 5 can also be used normally, improving the overall flexibility of the device.

[0042] Embodiment 2: Different from Embodiment 1, by setting the transmission shaft 19, the protective film, and the scale markings 6, the operator can quickly understand the unfolding angle of the first insertion plate 3, improving the overall precision of the device. As Figure 5 shown:

[0043] A traction rope 18 is fixedly connected to the upper surface of the movable plate 11, and the other side of the traction rope 18 is fixedly connected to a protective film, and the protective film covers the scale markings 6. The scale markings 6 are angle markings, and the other side of the protective film is wound and fixedly connected to the surface of the transmission shaft 19.

[0044] When the movable plate 11 descends, the movable plate 11 unfolds the protective film through the traction rope 18. Then, the protective film will gradually cover the scale markings 6. For the scale markings 6 that are not covered, the value closest to the position inside the connecting plate 4 is the angle value at which the first insertion plate 3 unfolds. Thus, it is convenient for the operator to precisely control the angle, improving flexibility.

[0045] Embodiment 3: Different from Embodiment 2, by setting the torsion spring 20, the transmission shaft 19 can be rotated back, and the protective film can be wound up for the next use. As Figure 6 shown:

[0046] A torsion spring 20 that plays an elastic reset role is fixedly connected to the surface of the transmission shaft 19, and the other side of the torsion spring 20 is fixedly connected to the inner wall of the connecting plate 4.

[0047] When the transmission shaft 19 rotates, the transmission shaft 19 will stretch the torsion spring 20. When the threaded rod 9 is rotated back, the movable plate 11 rises. At this time, the first insertion plate 3 rotates back. At the same time, the transmission shaft 19 loses the pulling force of the traction rope 18. Then, the transmission shaft 19 rotates back under the action of the torsion spring 20. When the transmission shaft 19 rotates back, it will wind up the protective film for subsequent use.

[0048] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
