[0031] Specifically, the workbench 1 is used to connect and protect the clamping assembly, the motor 2 is to output power to the clamping assembly, the motor 2 drives the first gear 3 to rotate, both the first gear 3 and the second gear 5 are bevel gears, through the meshing between them, the rotating rod 4 is driven to rotate, the rotating rod 4 drives the turntable 6 to rotate, the turntable 6 will push the push rod 7, and at this time the clamping plate 9 will move. The clamping plate 9 is used to clamp the electronic circuit board to ensure the stability of the electronic circuit board and prevent it from moving randomly. The limiting rod 8 is to limit the movement direction of the clamping plate 9 to ensure that the clamping plate 9 can only move left and right towards the center and will not move randomly. The sliding frame 10, the fixing member 11 and the nozzle 12 are all dispensing devices, and the rubber pad 21 is used to protect the electronic circuit board and prevent wear during clamping.

[0032] Refer to Figure 1 - Figure 3 , the replacement component includes a housing 13, the rear side of the housing 13 is fixedly connected to the front side of the fixing member 11, a sliding rod 14 is fixedly connected to the front side of the inner wall of the fixing member 11, a spring 15 is sleeved on the outside of the sliding rod 14, a plug rod 16 is fixedly connected to the rear end of the spring 15, a connecting rod 17 is rotatably connected to the front side of the outer wall of the plug rod 16, a baffle 18 is rotatably connected to the top of the connecting rod 17, a pull rod 19 is fixedly connected to the top of the baffle 18, the outer circumference of the baffle 18 is slidably connected to the inner wall of the housing 13, the pull rod 19 is slidably connected to the inside of the upper side of the housing 13, the front end of the spring 15 is fixedly connected to the front side of the inner wall of the housing 13, the inner wall of the plug rod 16 is slidably connected to the outside of the sliding rod 14, the outside of the plug rod 16 passes through the housing 13 and the fixing member 11 and is inserted into the inside of the nozzle 12, and a handle 20 is fixedly connected to the top end of the pull rod 19.

[0033] Specifically, the outer shell 13 is used to fix and protect the internal parts. The sliding rod 14 is used to control and limit the movement direction of the plug rod 16, ensuring that the plug rod 16 can only move back and forth without random movement or wobbling. The two ends of the spring 15 are fixed. By compressing the spring 15, the normal operation of the plug rod 16 is ensured. The connecting rod 17 is used to compress the spring 15. Under the limitation of the outer shell 13, the baffle 18 can only move up and down. The pull rod 19 is connected to the baffle 18, and a handle 20 is fixed at its top for convenient pulling of the pull rod 19.

[0034] Working principle: When working, to fix the electronic circuit board, first control the motor 2 to rotate through an external power supply. The motor 2 drives the first gear 3 to rotate. Through the meshing between the first gear 3 and the second gear 5, the rotating rod 4 is driven to rotate. The two turntables 6 connected to the rotating rod 4 will rotate accordingly, pulling the push rod 7 to drive the clamping plate 9 to move towards the middle together under the limitation of the limiting rod 8, firmly clamping the electronic circuit board to ensure that the electronic circuit board does not move randomly or wobble, facilitating the operation of workers. When not in use for a long time, the glue remaining inside the nozzle 12 will solidify and cause blockage, and the nozzle 12 will be scrapped. At this time, it is necessary to replace the nozzle 12 in time to avoid affecting the work process. First, pull the handle 20. The handle 20 drives the pull rod 19 to move upward, causing the baffle 18 to drive the connecting rod 17 to be straightened. The connecting rod 17 pulls the plug rod 16 out of the nozzle 12 to achieve unlocking, and then remove the old nozzle 12 and replace it with a new one. At this time, release the handle 20. Under the limitation of the sliding rod 14, the spring 15 pushes the plug rod 16, pushing the plug rod 16 out and reinserting it into the nozzle 12 to achieve quick replacement.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
