One end of the inner side of the mounting base 1 is slidably connected with a top pressure plate 34 which contacts with the two locking clamps 31 to drive the two locking clamps 31 to disengage from the clearance groove 33. The top pressure plate 34 is a U-shaped structure, and the two vertical sections of the top pressure plate 34 contact with the locking clamps 31. One end of the top pressure plate 34 is hinged with a pneumatic component 4 for driving the top pressure plate 34 to slide.

[0022] The pneumatic assembly 4 is used to drive the top pressure plate 34 to slide, so that the top pressure plate 34 contacts the two locking clips 31 and applies a thrust thereto, which causes one end of the two locking clips 31 to approach each other, and also causes the two locking clips 31 to disengage from the corresponding clearance grooves 33, while the other ends of the two locking clips 31 move away from each other, so that the first tension spring 32 is stretched to accumulate elastic potential energy. At this time, the two locking clips 31 lock the frame, so that the mounting seat 1 remains fixed to the frame, thereby achieving quick installation and locking of the mounting seat 1. Among them, the pneumatic component 4 includes a connecting sleeve 41, one end of the connecting sleeve 41 is fixedly connected to the top pressure plate 34, the other end of the connecting sleeve 41 is slidably connected to a fixing rod 42, one end of the fixing rod 42 is fixedly connected to the inner wall of the mounting seat 1, a tension spring 43 is sleeved on the fixing rod 42, one end of the tension spring 43 is in contact with the connecting sleeve 41, the other end of the tension spring 43 is in contact with the inner wall of the mounting seat 1, the tension spring 43 is in a stretched state, the diameter of the tension spring 43 is smaller than the outer diameter of the connecting sleeve 41, a connecting pin 45 is fixedly connected to the outer side of the connecting sleeve 41, one end of the connecting pin 45 is rotatably connected to a rotating plate 44, a limiting groove 46 that slides with the connecting pin 45 is provided on the rotating plate 44, one end of the rotating plate 44 is hinged with a connecting rod 48, and the end of the connecting rod 48 away from the rotating plate 44 is provided with a pneumatic pusher 47 for driving the connecting rod 48 to move. The pneumatic push piece 47 drives the connecting rod 48 to move, causing the rotating plate 44 to rotate, which changes the position of the limiting groove 46. At this time, under the action of the tension spring 43, the connecting pin 45 can slide along the limiting groove 46, causing the connecting sleeve 41 to slide, which changes the position of the top pressure plate 34.

[0023] Among them, the pneumatic pusher 47 includes a cylinder 471, one end of the cylinder 471 is hinged to the inner wall of the mounting base 1, the output end of the cylinder 471 is hinged to the connecting rod 48, the air inlet of the cylinder 471 is fixedly connected to the first air duct 472, the first air duct 472 is fixedly connected to the solenoid valve 473, the inlet end of the solenoid valve 473 is fixedly connected to the second air duct 474, the inlet end of the second air duct 474 is fixedly connected to the micro air pump 475, and the micro air pump 475 is fixedly connected to the inner side of the mounting base 1.

At this time, the two locking clamps 31 lock the frame, so that the mounting seat 1 and the frame remain fixed, which realizes the rapid installation and locking of the mounting seat 1;

[0025] When unlocking, the output end of the cylinder 471 is extended by controlling the solenoid valve 473, so that the rotating plate 44 rotates, and the connecting pin shaft 45 slides along the limit groove 46 to the other end of the limit groove 46, which causes the top pressure plate 34 to disengage from the two locking clamps 31. At this time, the first tension spring 32 releases potential energy, so that the ends of the two locking clamps 31 that are in contact with the frame move away from each other, thereby causing the locking clamps 31 to disengage from the frame, thereby achieving rapid contact of the mounting seat 1.
