Portable adjustable sucker

[0015] The present invention will be further described in detail below with reference to the drawings and specific embodiments: take this as an example to further describe the application.

[0016] This embodiment provides a portable adjustable suction cup, including: an upper suction cup and a lower suction cup; the upper suction cup is provided with suction grooves inside, and locking grooves are provided on both sides of the upper suction cup, and the suction holes a are distributed on the upper suction cup On the bottom plate of the bottom plate, upper suction cup guide grooves are provided on both sides of the bottom of the bottom plate; both sides of the lower suction cup are provided with convex edges, which are respectively located in the corresponding upper suction cup guide grooves, and the suction holes b are distributed on the bottom plate of the lower suction cup An upper suction cup fixing handle is provided at one end of the upper suction cup, a lower suction cup fixing handle is provided at one end of the lower suction cup, the upper suction cup fixing handle is provided with screw holes a, and the lower suction cup fixing handle is provided with a set of screw holes b , The fixing screw passes through the screw hole a and one of the screw holes b to fix the upper suction cup and the lower suction cup. There are locking screw holes a around the upper suction cup, and the locking screw holes a are connected to the locking groove; there are a set of locking screw holes b around the lower suction cup, and the locking screws pass through the locking screw holes a. Lock the upper suction cup and the lower suction cup with the corresponding locking screw hole b. There are multiple rows of suction holes a uniformly distributed on the bottom plate of the upper suction cup; multiple rows of suction holes b are uniformly distributed on the bottom plate of the lower suction cup, and the number of each row of suction holes b increases sequentially from both sides to the middle. The suction hole a and part of the suction hole b form a connected suction hole. The number of lower suction cup locking screw holes b corresponds to the number of lower suction cup screw holes b. Different lower suction cup screw holes b correspond to different lower suction cup locking screw holes b; different screw holes b correspond to different suction cup widths; according to different sizes of flexibility On the circuit board, the suction holes b of the corresponding size are arranged on the lower suction cup.

[0017] In this application, the upper suction cup is fixed on the suction cup holder; the suction length of the suction cup is fixed, and the width of the suction cup can be adjusted according to the front and back movement of the lower suction cup. Insert the lower suction cup along the upper suction cup guide groove and adjust the bottom according to the required width Position the suction cup so that the lower suction cup screw hole b is aligned with the upper suction cup screw hole a, and the fixing screw passes through the upper suction cup screw hole a and the lower suction cup screw hole b to fix the position of the lower suction cup, and at the same time the corresponding lower suction cup suction hole b coincides with the upper suction hole a to control the suction width of the suction cup. Then use the locking screw to lock the upper and lower suction cups.

[0018] The above are only to create preferred specific implementations of the present invention, but the scope of protection created by the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the present invention The created technical solution and its inventive concept shall be replaced or changed equivalently, and shall be covered by the protection scope of the invention.
