[0025] Please refer to Figures 1-8 The utility model provides an embodiment: a sucking disc, including shell 1, one side of shell 1 is connected with the soft body of sucking disc 2 set up, and the other side of shell 1 is equipped with the sliding piece 5 that is linked with the soft body of sucking disc 2, shell 1 is still equipped with dial block 3, and dial block 3 is connected with sliding piece 5 through the linkage shaft 6 set up, through the rotation of dial block 3 on shell 1, sliding piece 5 is moved upwards to make the soft body of sucking disc 2 linked with sliding piece 5 and be adsorbed on the contact surface or separate from the contact surface.

[0026] In summary, when the finger part presses the knob 3, the end of the knob 3 is pressed against the shell 1, and as the finger part continues to exert force, the end of the knob 3 will rotate with the point of contact with the shell 1 as the fulcrum, so that the sliding member 5 can easily and easily cause the soft body 2 of the suction cup to deform, realize the suction cup and the contact surface. Based on this, the setting of the knob can greatly reduce the pressure of the fingers, and at the same time, it can also avoid the discomfort caused by excessive force of the fingers.

[0027] In order to improve the adsorption force of the soft body 2 of the suction cup, the shell 1 facing the soft body 2 of the suction cup is also provided with a first pressure ring 10 and a second pressure ring 11, and the first pressure ring 10 and the second pressure ring 11 are concentrically arranged; wherein the outer end of the second pressure ring 11 extends towards the soft body 2 of the suction cup and protrudes from the shell 1. When the first pressure ring 10 and the second pressure ring 11 are pressed on the soft body of the suction cup, the space formed by the inner side of the first pressure ring 10 can make the soft body 2 of the suction cup have enough deformation space, and under the joint action of the two pressure rings, the soft body 2 of the suction cup can be reliably pressed on the contact surface. Especially, the second pressure ring 11 protrudes from the shell 1, so that the second pressure ring 11 can intervene in advance to press the soft body 2 of the suction cup for the first time, and then the first pressure ring 10 intervenes to press the soft body 2 of the suction cup again. By using successive compaction, the internal negative pressure space of the soft body 2 of the suction cup can be reliably and durably maintained, so as to enhance the stability of the device on the contact surface; specifically, the distance between the outer end of the second pressure ring 11 and the opposite surface of the shell 1 is 1-2 mm. When the distance between the two is 1.3 mm, the adsorption force between the soft body 2 of the suction cup and the contact surface reaches the optimum.

[0028] On the basis of the above-mentioned scheme, the shell 1 is also provided with a guide rod 13, and the knob 3 is also provided with a sliding groove 30, which slides along the guide rod 13 to guide the rotation of the knob 3 on the shell 1. Therefore, when the sliding groove 30 slides along the guide rod 13, the rotation direction of the knob 3 is controlled, so that the knob 3 can stably and reliably drive the sliding member 5 to move. Wherein, the guide rod 13 can be integrally formed with the shell 1, or can be movably installed on the shell 1, that is, the guide rod 13 is first processed and formed, and then inserted into the hole provided on the shell 1. In addition, the lower part of the shell 1 is also provided with a plug-in part 15, at this time two shells 1 are inserted from both ends of the hook to fix the hook on the contact surface.

[0029] Further, one end of the dial block 3 is provided with a dial groove 31, and the other end of the dial block 3 is provided with a force arm 32; wherein the linkage shaft 6 passes through the force arm 32 to install the sliding piece 5 on the dial block 3, and rotates on the shell 1 through one end of the force arm 32, so that the dial block 3 drives the sliding piece 5 to move upward or downward. The setting of the dial groove 31 is also convenient for the user to pick up the dial block 3 with the fingers. When the fingers pick up the dial block 3, pull the dial block 3 counterclockwise to move the sliding piece 5 upward, so as to separate the soft body 2 of the suction cup from the contact surface. In addition, the outside of the connecting part 22 is also sleeved with a spring 4, so that when the dial block 3 rotates counterclockwise, the spring 4 can be used to enlarge the gap between the soft body 2 of the suction cup and the facing surface of the shell 1, so that the soft body 2 of the suction cup is separated from the two compression rings, and the external air source enters the vacuum area formed by the soft body 2 of the suction cup, to release the adsorption force between the soft body 2 of the suction cup and the contact surface.

[0030] Wherein, the soft body 2 of the suction cup is also provided with a connecting part 22, and the two sides of the connecting part 22 are also provided with a protruding part 20, and one end of the connecting part 22 passes through the guide groove 14 provided on the shell 1, and the protruding part 20 is connected with the hook body 55 provided on the sliding piece 5. Therefore, the soft body 2 of the suction cup can realize stable and reliable linkage relationship with the sliding piece 5.

[0031] At the same time, the hook body 55 is provided with a brake part 51 and a guide part 52, and a limiting groove 54 is arranged below the guide part 52; wherein the protruding part 20 slides between the brake part 51 and the limiting groove 54 through the first arc surface 21. Therefore, when the sliding piece 5 moves downward, the protruding part 20 moves along the guide part 52 to the brake part 51, to make the soft body 2 of the suction cup deform; on the contrary, when the sliding piece 5 moves upward, the protruding part 20 slides from the brake part 51 to the guide part 52, and under the action of the spring 4, the protruding part 20 completely enters the limiting groove 54, so that the soft body 2 of the suction cup can be completely separated from the two compression rings, and the limiting groove 54 can also prevent the protruding part 20 from separating from the hook body 55. Especially, the setting of the first arc surface 21 can reduce the friction resistance between the sliding piece 5 and the soft body 2 of the suction cup.

[0032] In order to improve the structural strength of the sliding piece 5, the upper end of the hook body 55 is further provided with a supporting part 50; at the same time, the supporting part 50 is provided with a insertion hole 56 for facilitating the insertion of the linkage shaft 6, so that the insertion of the linkage shaft 6 is facilitated; wherein the insertion hole 56 is preferably a waist-shaped slot; so that the linkage shaft 6 can ensure reliable linkage between the dial block 3 and the sliding piece 5 without interfering with the power transmission between the dial block 3 and the sliding piece 5; in particular, since the supporting part 50 is further provided with a third arc surface 53, the interference between the dial block 3 and the sliding piece 5 during mutual rotation can be further reduced, so that the sliding piece 5 does not generate a large resistance to the dial block 3 during smooth rotation of the dial block 3, so that the rotation of the dial block 3 is smooth and smooth, and the dial block 3 rotates on the shell 1 through the second arc surface 33.

[0033] Therefore, the first arc surface 21, the second arc surface 33 and the third arc surface 53 can reduce the interference between parts during power transmission, so that the power transmission between parts is smoother, and the device can reduce the force output of the user's fingers during use, so that the device has the advantages of smooth operation, stable operation and small operation force.

[0034] In order to make the sliding piece 5 as much as possible to promote the soft body 2 of the suction cup to generate a larger negative pressure space, the shell 1 is further provided with a guide surface 12; wherein when the sliding piece 5 moves upward, the side of the sliding piece 5 facing the soft body 2 of the suction cup slides along the guide surface 12. Based on this, when the sliding piece 5 slides upward along the guide surface 12, the soft body 2 of the suction cup can be stretched as much as possible to the inside of the shell 1 under the action of the sliding piece 5, so that the negative pressure space formed by the soft body 2 of the suction cup is increased.
