Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example 1, such as Figure 1 As shown, this embodiment discloses a portable dual suction cup suction device, including two fixed handles 1 that are symmetrically arranged on the left and right sides. The two fixed handles are connected by a handle 10. A housing 2 is fixedly installed at the bottom of each fixed handle. A rubber suction cup 3 is installed at the bottom of the housing, and the size of the rubber suction cup is larger than the outer diameter of the housing so that the rubber suction cup can adhere more firmly.

[0026] An opening is made at the top of the housing, and a vertical connecting rod 4 is installed inside the opening, such as... Figure 3 As shown, the bottom of the vertical connecting rod 4 is fixedly connected to the rubber suction cup 3, and the top is hinged to the rotating bracket 7. A movable handle 8 is installed on the top of the rotating bracket, and the two movable handles are connected by a pull handle 80.

[0027] like Figure 2 As shown, a wire threaded sleeve 11 is provided on the contact surface between the fixed handle and the housing 2. A countersunk hole is provided on the housing opposite to the wire threaded sleeve, and a cross-head countersunk screw 12 passing through the countersunk hole is screwed into the wire threaded sleeve. The wire threaded sleeve helps to make the connection between the fixed handle and the housing more secure and reliable. The countersunk hole prevents the cross-head countersunk screw from protruding from the inner surface of the housing, thus not affecting the normal operation of the vertical connecting rod. The screw connection between the fixed handle and the housing facilitates disassembly and is convenient and quick.

[0028] like Figure 4 As shown, a glued joint 40 is threaded onto the bottom of the vertical connecting rod 4, making the connection between the two more secure and reliable. The glued connection between the rubber suction cup and the glued joint increases the strength and stability of the connection, extends its service life, and helps keep the upper and lower surfaces of the rubber suction cup parallel to the inner and outer surfaces of the housing.

[0029] A helical spring 41 is installed between the adhesive plate and the housing to allow the movable handle to return to its original position. The helical spring is fitted onto the vertical connecting rod.

[0030] A protective plate 5 is installed at the top of the housing, opposite the rotating bracket, with holes for the vertical connecting rod to pass through. The protective plate prevents the outer surface of the housing from being scratched by the rotation of the rotating bracket.

[0031] Holes are made in opposite positions on the vertical connecting rod and the rotating bracket, and the rotating shaft 6 is inserted into these holes to hinge the vertical connecting rod and the rotating bracket together for quick disassembly. Figure 5 As shown, a protrusion is provided at one end of the rotating shaft 6, and a retaining ring 61 is installed at the other end. During installation, the end of the rotating shaft without the protrusion is first inserted into the hole of the vertical connecting rod and the rotating bracket, and the vertical connecting rod and the rotating bracket are threaded together. Then, the retaining ring is installed on this end. The axial displacement of the rotating shaft is restricted by the cooperation of the protrusion and the retaining ring, thereby improving the stability and reliability of the hinged connection between the vertical connecting rod and the rotating bracket.

[0032] like Figure 6 As shown, a wire thread insert 81 is provided on the contact surface between the movable handle and the rotating bracket 7. A countersunk hole is provided on the rotating bracket opposite to the wire thread insert, and a cross-head countersunk screw 82 passing through the countersunk hole is screwed into the wire thread insert. The wire thread insert helps to make the connection between the movable handle and the rotating bracket more secure and reliable, and the countersunk hole prevents the cross-head countersunk screw from protruding from the lower surface of the rotating bracket. The screw connection between the movable handle and the rotating bracket facilitates disassembly and is convenient and quick.

[0033] Four semi-circular protrusions are provided on the fixed handle, and four grooves are provided on the movable handle. The four semi-circular protrusions and four grooves are positioned opposite each other and cooperate with each other to prevent fingers from being pinched during operation.

[0034] Except for the wire thread insert 11, wire thread insert 81, rubber suction cup 3, and helical spring 41, all other components are made of 316L stainless steel to improve the corrosion resistance, structural stability, and service life of the suction device.
