[0043] Embodiment 1

[0044] Refer to Figures 1 to 3, a schematic diagram of the overall structure of a fastening mechanism is provided. A fastening mechanism includes a fastening component 100, which includes a base 101 and an abutting portion 102 disposed at a position near the edge of the upper surface of the base 101; a control component 200, which includes a transmission portion 201 disposed on the abutting portion 102, a control portion 202 disposed on the transmission portion 201, and an elastic portion 203 disposed on the control portion 202; wherein, the transmission portion 201, the control portion 202 and the elastic portion 203 are all disposed inside the base 101.

[0045] Specifically, there are two sets of transmission portions 201. The two sets of transmission portions 201 are centrosymmetric about the center of the disc 202a of the locking portion. Each set of transmission portions 201 is connected with three abutting portions 102, and the abutting portions 102 on both sides are symmetric with each other.

[0046] In summary, the control portion 202 can drive the two transmission portions 201 to move synchronously. The two moving portions can drive the three abutting portions 102 connected thereto to move synchronously. The six abutting portions 102 can synchronously switch between the abutting state and the released state. The elastic portion 203 can make the six abutting portions 102 all in the abutting state when the control portion 202 is not subjected to an external force. The control portion 202 can release the abutting state of the abutting portion 102 by controlling the transmission portion 201. When the control portion 202 is released, the elastic portion 203 can switch the abutting portion 102 back to the abutting state through the transmission portion 201, and the elastic portion 203 makes the abutting portion 102 closely abut.

[0047] Embodiment 2

[0048] Referring to Figures 3 to 6 , the difference between this embodiment and the first embodiment is that the abutting portion 102 includes a fixed block 102a fixedly disposed on the upper surface of the base 101, an abutting member 102b disposed on the upper side of the fixed block 102a, and a trigger block 102c located on the upper surface of the base 101; wherein, the trigger block 102c is in contact with the abutting member 102b. The six abutting portions 102 are arranged in two rows, left and right, and one row is provided with three connecting portions.

[0049] Specifically, the abutting member 102b includes a rotating rod movably disposed on the upper part of the fixed block 102a, a convex block 102b-3 fixedly disposed on the bottom side of the front end of the rotating rod, and a rotating block 102b-1 rotatably disposed at the tail end of the rotating rod; the moving block is in contact with the trigger block 102c. A torsion spring is disposed between the rotating rod and the fixed block 102a. The upper surface of the trigger block 102c is inclined, and the side of the upper surface away from the rotating block 102b-1 is higher than the side close to the rotating block 102b-1.

[0050] When the trigger block 102c approaches and presses against the trigger block 102c, the trigger block 102c can only drive the rotating rod to rotate clockwise around the fixed block 102a. The rotating rod drives the convex block 102b-3 at its front end to rotate downward until it contacts and clamps the component that the abutting portion 102 needs to abut against. The torsion spring can keep the convex block 102b-3 on the rotating rod in the abutting state. If you want to release the abutting portion 102, just move the trigger block 102c away from the fixed block 102a, and the torsion spring will automatically rebound, driving the rotating rod to rotate counterclockwise, so that the convex block 102b-3 moves away from the component that needs to be abutted against.

[0051] The transmission part 201 includes a first connecting rod 201a arranged on the bottom surface of the trigger block 102c, a second connecting rod 201d fixedly arranged at the bottom of the first connecting rod 201a, and a moving plate 201b fixedly arranged on the side surface of the second connecting rod 201d; a limiting groove 201c is formed in the base 101, and the moving plate 201b is slidably arranged in the limiting groove 201c; the arrangement of the limiting groove 201c enables the moving plate 201b to only slide left and right. A first connecting rod 201a is arranged at the bottom of each trigger block 102c. Each transmission part 201 includes three first connecting rods 201a, and the three first connecting rods 201a are all connected to the same second connecting rod 201d. The three first connecting rods 201a are arranged in a row. When the control part 202 controls the left and right moving plates 201b to approach or move away from each other, it can drive the first connecting rod 201a and the second connecting rod 201d to move synchronously, and can drive the trigger block 102c to move synchronously, so that the trigger blocks 102c on the left and right sides approach or move away from each other, thereby achieving the purpose of uniformly controlling the synchronous movement of multiple abutting parts 102.

[0052] Furthermore, the control part 202 includes a connecting column 202d rotatably arranged at one end of the moving plate 201b, a disc 202a fixedly arranged on the upper surface of the connecting column 202d, a fixed column 202b rotatably arranged at the center of the disc 202a, and a control rod 202c movably arranged on the right side of the disc 202a; the fixed column 202b is fixedly arranged on the base 101, and the control rod 202c extends out of the outer surface of the base 101. Operating the control rod 202c can control the rotation of the disc 202a. When the disc 202a rotates, it can drive the two connecting columns 202d on it to rotate synchronously. Similar to the transmission part 201, the two connecting columns 202d are centrosymmetric with respect to the center of the disc 202a. When the disc 202a rotates counterclockwise, it can drive the two moving plates 201b to approach each other, and when the disc 202a rotates clockwise, it can drive the two moving plates 201b to move away from each other.

[0053] The elastic part 203 includes a first fixing rod 203a fixedly arranged in the base 101, and a second fixing rod 203b fixedly arranged at one end of the upper surface of the moving plate 201b close to the disc 202a. There are two second fixing rods 203b in total. The two second fixing rods 203b and one first fixing rod 203a are all parallel to each other, and the direction in which they are parallel is perpendicular to the moving path of the moving plate 201b. A first spring 203c is fixedly arranged between the first fixing rod 203a and the second fixing rod 203b. There are two parallel first springs 203c between the left second fixing rod 203b and the first fixing rod 203a, and there are also two parallel first springs 203c between the right second fixing rod 203b and the first fixing rod 203a. The four first springs 203c are all arranged parallel to the moving path of the moving plate 201b, and the two moving plates 201b on both sides are symmetrical to each other. It should be noted that under normal conditions when the disc 202a is not affected by external forces, the first springs 203c on both sides pull the corresponding moving plates 201b inward respectively, and the elastic force of the torsion spring is less than the elastic force of the spring, so that the abutting part 102 is in the abutting state in the natural state.

[0054] Referring to Figure 3 , in summary, in the initial state, the abutting part 102 is in the abutting state, the bottom end of the convex block 102b-3 is in close contact with the component to be fastened, the rotating rod is in the state of being higher on the left and lower on the right. When it is necessary to loosen the abutting part 102, move the control rod 202c in the direction away from the disc 202a, which can drive the disc 202a to rotate clockwise, thereby driving the two moving plates 201b on both sides to move away from each other. The first springs 203c on both sides are stretched. The transmission part 201 drives the trigger blocks 102c to move away from their respective corresponding fixed blocks 102a. Due to the elastic force of the torsion spring, the rotating rod rotates counterclockwise, the convex block 102b-3 moves upward, and the abutting part 102 is in the loosened state. When it is necessary to make the abutting part 102 return to the abutting state, just loosen the control rod 202c, and the first springs 203c will all rebound, thereby driving the two moving plates 201b on both sides to move closer to each other, and then the abutting part 102 returns to the abutting state.

[0055] All the other structures are the same as those in Embodiment 1.

[0056] Embodiment 3

[0057] Referring to Figure 1 and Figures 7 to 9 , the difference between this embodiment and the above embodiments is that: a flexible concentrating solar cell preparation device includes the fastening mechanism in any one of the above embodiments, and further includes a back plate 300, a first groove 301 opened in the upper part of the back plate 300, a cover plate 302 sleeved in the first groove 301, and a lining plate main body 303 placed in the first groove 301; the cover plate 302 covers the lining plate main body 303, and the lining plate main body 303 is located between the back plate 300 and the cover plate 302.

[0058] Specifically, the cover plate 302 includes a square frame 302a and a retaining wall 302b fixedly arranged at the outer edge of the bottom of the square frame 302a. The outer edges of the retaining wall 302b and the square frame 302a are in contact with the inner edge of the first groove 301, the side edge of the lining plate main body 303 is in contact with the inner edge of the retaining wall 302b, and the part of the upper surface of the lining plate main body 303 near the edge is pressed by the square frame 302a; a second groove 302c is formed inside the square frame 302a, and the inside of the second groove 302c is a deposition area. The shape of the second groove 302c can be changed, and the staff can design and select the cover plate 302 with different shapes of the second groove 302c according to actual needs, so as to generate different deposition areas to meet different needs of the staff.

[0059] Furthermore, the back plate 300 is slidably installed inside the base 101. A baffle 304 is movably arranged on the side of the base 101. A second spring 305 is fixedly arranged at the bottom of the baffle 304, and the second spring 305 is connected to the base 101. When using this device, first place the lining plate main body 303 into the first groove 301, then cover the back plate 300 on the lining plate main body 303 and place the back plate 300 into the first groove 301. Then pull the control rod 202c to release the abutting part 102, and then place the back plate 300 into the base 101 from the side of the base 101. During the placement process, the back plate 300 presses the baffle 304 and the second spring 305 until the back plate 300 is placed inside the base 101 and the baffle 304 pops out. The baffle 304 and the base 101 surround the four sides of the back plate 300. Then release the control rod 202c. When the lining plate needs to be removed, press the baffle 304, pull the control rod 202c to release the clamping part, and then slide the back plate 300 out. The sliding out of the back plate 300 will also press the baffle 304, and then release the control rod 202c.

[0060] In summary, the six abutting parts 102 simultaneously press the cover plate 302 and are distributed at the edge of the cover plate 302. The square frame 302a presses the upper surface of the substrate main body. The cooperation between the first groove 301 and the back plate 300 can lay and press the substrate main body flat. The clamping part can tightly press the cover plate 302 on the substrate main body and make the force evenly distributed. The boundary between the deposition area and the non-deposition area on the substrate main body is clear, and the abutting part 102 does not directly contact the substrate main body, so it is not easy to damage the substrate main body.

[0061] All the other structures are the same as those in Embodiment 2.
