[0030] As shown in the figure, Figures 2-3 The clamping piece 33 includes a left clamping arm 331, a right clamping arm 332 and a mounting column 15, a torsion spring 333 is arranged between the left clamping arm 331 and the right clamping arm 332, the left clamping arm 331, the torsion spring 333 and the right clamping arm 332 are sleeved on the mounting column 15, under the condition of no external force, the left clamping arm 331 and the right clamping arm 332 are clamped to each other through the torsion spring 333, the clamping portions of the left clamping arm 331 and the right clamping arm 332 are formed with a clamping opening 334 for clamping the inflation port end 21, the lower ends of the clamping portions of the left clamping arm 331 and the right clamping arm 332 are provided with a clamping tooth 335, the inflation port end 21 is provided with an annular clamping groove 22 matched with the clamping tooth 335, the upper end surface of the clamping tooth 335 is an inclined surface, and the upper and lower end surfaces of the annular clamping groove 22 are both inclined surfaces, so as to facilitate locking or unlocking of the air pipe 2 by the clamping piece 33, the upper end of one side of the clamping portions of the left clamping arm 331 and the right clamping arm 332 is provided with an opening, the inflation port end 21 is pushed to the opening side to press the left clamping arm 331 and the right clamping arm 332, and at the same time, the clamping tooth 335 is pressed, and the left and right clamping arms are respectively opened to the left and right under the action of force.

[0031] It should be noted that when the inflation port end 21 is clamped by the clamping piece 33, the clamping tooth 335 is located in the annular clamping groove 22, the lower end of the inflation port end 21 extends out of the clamping piece 33 and presses the pressing plate 31, the spring 32 is compressed under the action of force, and the pressing block 313 presses the switch 16.

[0032] As shown in the figure, Figure 3 The lower ends of the clamping portions of the left clamping arm 331 and the right clamping arm 332 are provided with a guide opening, and the two sides of the pressing plate 31 are symmetrically provided with a guide block 311 matched with the guide opening to play a guiding role, the side surfaces corresponding to the guide opening and the guide block 311 are both inclined surfaces in the same direction as the movement direction of the left clamping arm 331 or the right clamping arm 332, so as to ensure that the left and right clamping arms 332 are not hindered when rotating, and the left and right clamping arms 332 are respectively rotated to the left and right sides around the mounting column 15 when being opened under the action of force.

[0033] As shown in the figure, Figure 3 , Figure 6 The lower end of the pressing plate 31 is recessed with a recess 312, and one end of the spring 32 extends into the recess 312. The bottom of the pressing groove 13 is provided with a positioning column 131, and the other end of the spring 32 is sleeved on the positioning column 131 to prevent the spring 32 from coming out.

[0034] like Figure 5 As shown, the air pump 1 has a top cover 11 at its upper end, which covers the clamping member 33. The top cover 11 has a locking slot 111, which is larger than the air inlet end 21 of the air tube 2. The top cover 11 is marked with patterns indicating locking and unlocking. The unlocking pattern corresponds to the opening side of the clamping part. The air tube 2 can be unlocked by moving the air inlet end 21 in the unlocking direction.

[0035] When the air pump 1 is needed, manually move the air inlet end 21 towards the unlock mark indicated by the lock 111. At this time, the left clamping arm 331, the right clamping arm 332, and the locking teeth 335 are compressed. The left clamping arm 331 and the right clamping arm 332 rotate to the left and right sides respectively around the mounting post 15. The air inlet end 21 loses the clamping force of the clamping member 33, and the spring 32 presses the pressure plate 31. The pressure plate 31 pushes out the air inlet end 21, completing the unlocking of the air tube 2. At the same time, the pressure plate 31 drives the pressure block 313 to move upward, no longer compressing the actuating spring of the switch 16. The actuating spring no longer presses the contact point, that is, the switch 16 is turned on, the power is turned on, and the air pump 1 is started.

[0036] When the inflation port end 21 is clamped by the clamping member 33, the locking teeth 335 are located in the annular locking groove 22, the lower end of the inflation port end 21 extends out of the clamping member 33 and presses the pressure plate 31, the spring is compressed, and the pressure block 313 presses the switch 16.

[0037] After use, insert the air inlet end 21 of the air tube 2 into the clamping port 334 through the locking port 111 and press it down. The upper inclined surface of the locking tooth 335 is subjected to the squeezing force. The left clamping arm 331 and the right clamping arm 332 are subjected to the force and rotate to both sides with the mounting post 15 as the center. When the air tube 2 is inserted into the position corresponding to the locking tooth 335 in the annular groove 22, the left clamping arm 331 and the right clamping arm 332 lose the squeezing force of the air inlet end 21 and are clamped under the action of the torsion spring 333. The air inlet end 21 is clamped by the clamping member 33. At this time, the lower end of the air inlet end 21 extends out of the clamping member 33 and squeezes the pressure plate 31. The spring 32 is compressed by the force, and the pressure block 313 moves down with the pressure plate, squeezing the action spring of the switch 16. The action spring presses the contact point, that is, the switch 16 is closed and the air pump 1 stops working.

[0038] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
