The end of the first clamping block is provided with a first pipe groove 421, the end of the second clamping block 550 is provided with a second pipe groove 551, and the first pipe groove 421 and the second pipe groove 551 cooperate to form the pipe hole 1. By replacing the first clamping block and the second clamping block 550 of different sizes of the pipe hole 1, the device can adapt to straws of different sizes, and the applicability of the device is improved. The notch of the first pipe groove 421 is extended and provided with an outwardly expanded guide hole 422, which facilitates the operator to put the straw into the first pipe groove 421, and improves the fixing efficiency of the straw. The inner wall of the pipe hole 1 is provided with a layer of self-adhesive silica gel. The self-adhesive silica gel is a common adhesive with high adhesion and difficulty in leaving glue. The self-adhesive silica gel can strengthen the fixation of the pipe hole 1 to the straw.

[0026] As shown in Figure 4 、 5 , the clamp seat 400 and the clamp block assembly 500 are further provided with a buckle mechanism 2. Through the buckle mechanism 2, the clamp seat 400 and the clamp block assembly 500 can be quickly fixed or opened, and the efficiency of fixing the straw is improved. The clamp block assembly 500 comprises a clamp block main part 510 and a clamp block auxiliary part 530 connected with each other, the clamp block main part 510 is hinged to the end of the clamp seat 400, and the clamp block auxiliary part 530 is connected with the end of the clamp seat 400 through the buckle mechanism 2. The buckle mechanism 2 comprises a first hooking part 411 arranged at the front end of the clamp seat 400, one side of the clamp block auxiliary part 530 is provided with a second hooking part 531 matched with the first hooking part 411, the clamp block main part 510 is provided with a containing groove 511, the containing groove 511 is provided with a spring 512, the end of the containing groove 511 is provided with a cover plate 520, the cover plate 520 is provided with a through hole 521, the diameter of the through hole 521 is smaller than that of the containing groove 511, the end of the clamp block auxiliary part 530 is connected with a pressing block 540, the pressing block 540 comprises a pressing part 541 and a sliding part 542, the pressing part 541 is located in the containing groove 511 and slides and presses the spring 512, and the sliding part 542 slides on the through hole 521. The cover plate 520 can prevent the spring 512 from falling off, and at the same time, the clamp block main part 510 and the clamp block auxiliary part 530 can be stably connected together.

[0027] The accommodating groove 511 provides displacement space for the pressing block 540, and when the clamping block assembly 500 is fixed to the clamping seat 400, the first hooking part 411 and the second hooking part 531 can be hooked together by moving the clamping block assembly 500 towards the clamping seat 400, thereby clamping the suction tube. During the connection of the first hooking part 411 and the second hooking part 531, the first hooking part 411 and the second hooking part 531 are pressed against each other, and the end of the first hooking part 411 and the end of the second hooking part 531 are provided with inclined surfaces, which drive the second hooking part 531 to move the clamping block sub-piece 530 to one side.

The accommodating groove 511, the pressing part 541, the through opening 521 and the sliding part 542 are all quadrilateral structures, which can effectively prevent relative rotation between the clamping block sub-piece 530 and the clamping block main piece 510, thereby avoiding interference with the fixing work. In actual application, only the through opening 521 and the sliding part 542 need to be designed as polygonal structures, so that the clamping block main piece 510 and the clamping block sub-piece 530 cannot rotate relative to each other. The clamping block sub-piece 530 is further provided with a groove matched with the sliding part 542 on the side connected with the pressing block 540, thereby preventing relative rotation between the pressing block 540 and the clamping block sub-piece 530.
