That is, the positioning structure 152 and the main structure 130 can be connected and fixed through screws 153 to avoid shaking.

In this embodiment, the main structure 130 is in the form of an annular structure, and the upper side of the main structure 130 is connected to the positioning structure 152 . The lower side of the main structure 130 includes a plurality of through holes 131 , the suction cup 160 is corresponding to the through hole 131 , and the suction cup 160 is deeply installed in the through hole 131 via a mounting portion 162 (please refer to FIGS. 4A to 4D ). The number of suction cup nuts 140 is equivalent to the number of through holes 131 , and the suction cup nuts 140 cover the through holes 131 . The suction cup connecting rod 170 is disposed in the space surrounded by the annular structure of the main structure 130 . The suction cup connecting rod 170 includes a suction cup pull rod 170a and a connecting rod body 171, and the connecting rod 151 is connected to the connecting rod body 171.

In detail, most of the connecting rod 151 is located in the tubular connecting structure 150, and the connecting rod 151 is provided through the bottom 112 of the handle structure 110, the tubular connecting structure 150 and the main structure 130, and the two ends of the connecting rod 151 are respectively Use nuts to connect and fix the pull handle 120 and the connecting rod body 171 . In addition, connect The rod 151 can move up and down relative to the handle structure 110, the tubular connecting structure 150 and the main body structure 130. Therefore, when the user pulls the pulling handle 120 upward, the connecting rod body 171 can be pulled through the connecting rod 151 . In addition, both ends of the connecting rod body 171 are connected to the suction cup 160 via the suction cup pull rod 170a. The suction cup pull rod 170a passes through the through hole 131, the suction cup nut 140 and the connecting rod body 171 and are connected and fixed to each other to drive the suction cup 160 to move up and down. Please refer to FIGS. 4A to 4D , FIGS. 4A and 4B are schematic diagrams of the suction cup, FIG. 4C is a schematic diagram of the suction cup installation, and FIG. 4D is a schematic cross-sectional view of the suction cup. The suction cup includes a mounting part 162. The mounting part 162 is a tubular structure and forms a ventilation hole 161, and the ventilation hole 161 penetrates the suction cup 160. The suction cup 160 extends into the through hole 131 through the mounting portion 162 and is installed on the main structure 130 (see Figure 4C).

Further, please refer to FIG. 4D , the suction cup pull rod 170 a respectively includes a pull rod body 173 , a piston 172 , a blocking block 174 and a spring 175 . The tie rod body 173 penetrates the through hole 131 , the suction cup nut 140 and both ends of the connecting rod body 171 respectively. One end of the tie rod body 173 is provided with a piston 172 , and the other end is a blocking block 174 , and the piston 172 is against the ventilation hole 161 . Moreover, when the handle structure 110 is pressed down, the suction cup 160 adsorbs the object 10, and when the piston 172 abuts against the ventilation hole 161, the piston 172 can seal the ventilation hole 161 to keep the gas in the suction cup 160 from interacting with the external environment. In this way, when the suction cup 160 adsorbs an object, the pressure difference between the inside and outside of the suction cup 160 can be maintained, and the adsorption effect of the suction cup 160 can be maintained.

The blocking block 174 is in contact with the connecting rod body 171 , and the diameter of the blocking block 174 is larger than the diameter of the tie rod body 173 . Therefore, when the user pulls the pulling handle 120 upward so that the connecting rod body 171 is pulled up by the connecting rod 151, the blocking block 174 is pushed to pull the pulling rod body 173 and the piston 172, further causing the piston 172 to move upward away from the vent hole 161. As a result, the vent hole 161 is no longer sealed. One end of the spring 175 is connected to the inner hole 141 of the suction cup nut 140, and the other end is connected to the piston 172. When the piston 172 is pulled by the user to move upward, the spring 175 is compressed. When the user's pulling force disappears, that is, when the user releases the handle 120, the elastic force of the spring 175 can push the piston 172 back to the original position, that is, the position where the vent hole 161 is sealed.

Please refer to FIGS. 5A to 5C , which are schematic diagrams of the operation of the piston. Please refer to FIG. 5A first. When using the suction cup operating device 100 of this embodiment, the user first aligns the suction cup 160 with the adsorbed object 10 and presses down the handle structure 110. At this time, the suction cup 160 will be pressed down. The air inside 160 will be squeezed out from the edge of suction cup 160 . After the air is extruded from the space covered by the suction cup 160, because the air pressure in the space covered by the suction cup 160 is less than the air pressure outside the space covered by the suction cup 160, the suction cup 160 is pressed by the external atmospheric pressure and adheres. on the adsorbed object 10.

Please refer to Figure 5B. When the suction cup 160 is adsorbed on the adsorbed object 10, the air pressure in the suction cup 160 will be less than the atmospheric pressure of the external environment. At this time, the piston 172 is against and seals the ventilation hole 161, and is holding the suction cup 160 for adsorption. Effect. Next, please refer to FIG. 5C . When the connecting rod body 171 is pulled by the connecting rod 151 and moves upward, the blocking block 174 and the pull rod body 173 are pushed to move upward, further driving the piston 172 to move. At this time, since one end of the spring 175 is connected to the fixed suction cup nut 140, the upward moving piston 172 will compress the spring 175. When the piston 172 leaves the ventilation hole 161, the ventilation hole 161 is no longer sealed, and the air from the external environment will enter the inside of the suction cup 160 from the hole on the suction cup nut 140 and the ventilation hole 161, causing the air pressure in the suction cup 160 to further increase to The atmospheric pressure of the external environment is the same, thereby releasing the suction force of the suction cup 160 on the adsorbed object 10 . Subsequently, when the upward pulling force of the connecting rod body 171 stops, that is, when the user releases the pull handle 120, the elastic force of the spring 175 causes the piston 172 to return to the vent hole 161 (ie, the state in FIG. 4).

Please refer back to Figure 1. Therefore, when using the suction cup operating device 100, the user only needs to hold the handle structure 110, align the suction cup 160 with the adsorbed object 10, and apply downward pressure on the suction cup operating device 100, so that the suction cup 160 can be adsorbed. The object 10 is adsorbed, thereby moving the object 10 being adsorbed. To put down the adsorbed object 10, the user further pulls the handle 120 in the handle structure 110, and then pulls the suction cup connecting rod 170 through the connecting rod 151 in the tubular connecting structure 150, thereby pulling the piston 172 in the suction cup 160 to open it. The ventilation hole 161 releases the suction force of the suction cup 160, and the adsorbed object 10 can be put down. In the above operation, the user does not need to squat or bend down to complete. Compared with the traditional hand-held suction cup, which requires bending down to operate the suction cup 160, the suction cup operating device 100 of the present invention can absorb the adsorbed object 10 in a more labor-saving and convenient manner.

The invention is described above, but it is not intended to limit the scope of the patent rights claimed for this invention. The scope of patent protection shall depend on the appended patent application scope and its equivalent fields. Any changes or modifications made by those with ordinary knowledge in the art without departing from the spirit or scope of this patent shall be equivalent changes or designs completed within the spirit disclosed in this invention, and shall be included in the following patent application scope. within.
