The bottom ends of the two groups of chucks 203 are respectively fixedly connected to a group of No. 1 sliding frames 204. The No. 1 sliding frames 204 are slidably sleeved on the outer wall of the No. 1 push rods 202. The other sides of the two groups of turntables 201 are respectively fixedly connected to a group of No. 2 sliding frames 206. The inner walls of the two groups of No. 2 sliding frames 206 are respectively slidably sleeved with a group of No. 2 push rods 205. The fixing mechanism 3 includes a support leg 301, a connecting rod 302, and a suction cup. 303, sleeve 304, piston 305 and push rod 306, the bottom end of the shell 1 is slidably connected to multiple groups of support legs 301 extending outside the shell 1, the tops of the two groups of support legs 301 on the same side are fixedly connected to a group of connecting rods 302, the second sliding frame 206 is fixedly connected to the side wall of the connecting rod 302, the bottom end of the shell 1 is fixedly connected to two groups of suction cups 303, the inner wall of the shell 1 is fixedly connected to two groups of sleeves 304, the bottom ends of the two groups of sleeves 304 are respectively connected to a group of suction cups 303, the sleeves 304 The inner wall is slidably connected with a group of pistons 305, and the piston 305 is provided with a sealing ring at the contact position with the sleeve 304. The side walls of the two groups of support legs 301 close to the storage mechanism are respectively fixedly connected with blocks 307. The side wall of the outer shell 1 is slidably connected with two groups of baffle rods, and the top ends of the two groups of connecting rods 302 are fixedly connected with one end of a group of support springs 309, and the other ends of the two groups of support springs are fixedly connected to the top of the inner wall of the outer shell 1. Another group of support springs 309 is provided at the connection between the baffle rod 308 and the outer shell 1.

[0031] By placing the circuit board on the top of the shell 1, the circuit board is located between the two groups of clamps 203, and then pressing down the shell 1, so that the shell 1 pushes the support leg 301 to slide into the shell 1, and the connecting rod 302 is driven to move upward during the sliding process of the support leg 301, so that the connecting rod 302 compresses the support spring 309, and drives the stopper 307 to slide upward during the sliding process of the support leg 301, and contacts the stopper 307 during the sliding process of the stopper 307, so that the stopper is pushed and compressed by another group of support springs 309. When the stopper 307 slides over the stopper, the other group of support springs 309 pushes the stopper to reset, so that the support push rod cannot slide downward, and the piston 305 is driven to slide upward through the push rod 306 during the sliding process of the connecting rod 302, so that the air between the suction cup 303 and the desktop is collected in the sleeve 304, so that the suction cup 30 3 is tightly adsorbed on the desktop, and when the connecting rod 302 slides upward, it drives the second sliding frame 206 to move upward, and the second sliding frame 206 drives the second pushing rod 205 to make the turntable 201 rotate. During the rotation of the turntable 201, it drives the first pushing rod 202 to rotate, and during the rotation of the first pushing rod 202, it drives the first sliding frame 204, so that the two groups of first sliding frames 204 respectively drive the two groups of clamps 203 to approach each other to clamp the circuit board. When the circuit board needs to be released, the two groups of shift rods 308 are pulled so that the shift rods 308 no longer block the stopper 307. At this time, the support spring 309 drives the connecting rod 302 to move downward, so that the connecting rod 302 drives the supporting leg 301 to slide toward the outside of the housing 1. During the downward sliding process of the connecting rod 302, the piston 305 is driven to reset through the push rod 306, so that the suction cup 303 is no longer adsorbed on the desktop.

[0032] Please refer to Figure 1-8 The storage frame 4 includes a box body 401, a slider 402, a limit pin 403, a No. 1 connecting rod 404, and a handle 405. The box body 401 is slidably connected to the inner wall of the shell 1. The inner wall of the box body 401 is slidably connected with two groups of sliders 402 extending to the outside of the box body 401. One end of the two groups of sliders 402 located inside the box body 401 is respectively fixedly connected with a group of limit pins 403 extending to the outside of the box body 401. One end of the two groups of sliders 402 located outside the box body 401 is respectively hinged with one end of a group of No. 1 connecting rods 404. The other end of the two groups of No. 1 connecting rods 404 is hinged with a handle 405. The outer wall of the handle 405 is provided with a rubber sleeve. The two groups of No. 1 connecting rods 404 are respectively provided with a group of torsion springs at the connection with the handle 405. The inner wall of the shell 1 is provided with a limit groove corresponding to the limit pin 403.

[0033] Before welding, rosin or other soldering flux can be placed inside the box body 401. When the soldering flux is needed, the handle 405 is pulled so that the handle 405 pulls the two sets of sliders 402 closer to each other through the No. 1 connecting rod 404, so that the two sets of sliders 402 respectively drive a set of limit pins 403 to slide from the inside of the limit groove, and as the action of pulling the handle 405 continues, the box body 401 is pulled out from the inside of the outer box. In this process, as the two sets of sliders 402 continue to approach each other, the angle between the two sets of No. 1 connecting rods 404 and the pull plate continues to change, so that the No. 1 connecting rods 404 Twist the torsion spring, and when the box body 401 is pulled out, the handle 405 is released. At this time, the torsion spring drives the No. 1 connecting rod 404 to reset, thereby pushing the limit pin 403 to reset. When the box needs to be closed, the box body 401 is pushed to slide into the shell 1, so that the limit pin 403 is pushed by the shell 1 to slide into the box body 401, so that the slider 402 pushes the No. 1 connecting rod 404 to twist. When the limit pin 403 and the limit groove are aligned, the torsion spring pushes the No. 1 connecting rod 404 to reset, so that the limit pin 403 is inserted into the limit groove. At this time, the limit pin 403 is blocked by the limit groove, so that the box body 401 cannot slide out accidentally.

[0034] Please refer to Figure 1-8 The fixed sleeve 5 includes an outer cylinder 501, a clamping arm 502, a rotating arm 503, a sliding plate 504, a No. 2 connecting rod 505 and a reset spring 506. The outer cylinder 501 is fixedly connected to the side wall of the outer shell 1. The inner wall of the outer cylinder 501 is hinged with two groups of clamping arms 502. The side walls of the two groups of clamping arms 502 are respectively fixedly connected with a group of rotating arms 503. The inner wall of the outer cylinder 501 is slidably connected with a sliding plate 504. The top end of the sliding plate 504 is hinged with one end of two groups of No. 2 connecting rods 505. The other ends of the two groups of No. 2 connecting rods 505 are respectively rotatably connected to the end of a group of rotating arms 503. The bottom end of the sliding plate 504 is slidably fixedly connected with one end of a group of reset springs 506. The other end of the reset spring 506 is fixedly connected to the bottom end of the inner wall of the outer cylinder 501.

[0035] By inserting the electric soldering iron into the outer cylinder 501, the sliding plate 504 is pushed, so that the sliding plate 504 compresses the return spring 506. During the sliding process of the sliding plate 504, the sliding plate 504 pulls the two groups of rotating arms 503 to flip through the two groups of No. 2 connecting rods 505. The two groups of rotating arms 503 respectively drive the two groups of clamping arms 502 to rotate, so that the two groups of clamping arms 502 clamp the electric soldering iron. When the electric soldering iron is needed, the electric soldering iron is pulled toward the outside of the outer cylinder 501 to reduce the pressure on the sliding plate 504, so that the return spring 506 pushes the sliding plate 504 to reset. During the resetting process of the sliding plate 504, the No. 2 connecting rod 505 drives the rotating arm 503 to flip in the opposite direction. The reverse flipping of the rotating arm 503 drives the clamping arm 502 to flip in the opposite direction, thereby releasing the electric soldering iron, so that the electric soldering iron can be conveniently fixed and can be quickly taken out when in use.

[0036] When in use, the circuit board is placed on the top of the shell 1 so that the circuit board is located between the two groups of clamps 203, and then the shell 1 is pressed down, so that the shell 1 pushes the supporting legs 301 to slide into the inside of the shell 1, driving the piston 305 to slide upward, so that the air between the suction cup 303 and the desktop is collected into the sleeve 304, so that the suction cup 303 is tightly adsorbed on the desktop, and when the connecting rod 302 slides upward, it drives the second sliding frame 206 to move upward, and the second sliding frame 206 pushes the second pushing rod 205 to make the turntable 201 rotate, and the rotation of the turntable 201 drives the first sliding frame 204, so that the two groups of first sliding frames 204 respectively drive the two groups of clamps 203 to approach each other to clamp the circuit board, so that the circuit board can be conveniently fixed during the process of soldering electronic components, and the suction cup 303 can be tightly adsorbed on the desktop to prevent the shell 1 from displacement during the process of fixing the circuit board.
