All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-10, a convenient-to-use can opener for a round-mouth can comprises a fixed sleeve 1, wherein the fixed sleeve 1 is made of plastic, two movable grooves 2 are formed in the inner wall of the fixed sleeve 1, springs 3 are adhered to the inner bottom walls of the movable grooves 2, the springs 3 play a role in resetting the rotating sleeve 6, movable blocks 4 are adhered to the tops of the springs 3, the moving range of the movable blocks 4 in the movable grooves 2 is larger than the sum of the thicknesses of a turntable 7 and a slideway 8, so that when the springs 3 push the movable blocks 4 to the tops of the movable grooves 2, the turntable 7 and the slideway 8 can be completely accommodated in the fixed sleeve 1 to prevent a cutter 11 from hurting a person, a fixed bearing 5 is welded between the two movable blocks 4, and the fixed bearing 5 plays a role in fixedly supporting the rotating sleeve 6.

The inner side of the fixed bearing 5 is welded with a rotating sleeve 6, the bottom of the rotating sleeve 6 is provided with a through hole corresponding to the gear 12, an auxiliary bearing is installed in the through hole, the bottom of the rotating sleeve 6 is welded with a turntable 7, the turntable 7 is rectangular, the turntable 7 is positioned on the inner side of the fixed sleeve 1 when not in use and extends out of the fixed sleeve 1 when in use, two slide ways 8 are installed at the bottom of the turntable 7, the length of each slide way 8 is not less than half of the length of the turntable 7, racks 9 are movably connected in the slide ways 8, clamping blocks 10 are welded on the opposite sides of the two racks 9, one ends of the clamping blocks 10 far away from the racks 9 are connected with rollers in a rolling manner, anti-skidding lines are arranged on the outer sides of the rollers, the friction force between the rollers and the can cover is increased, the slippage is prevented, the shape of the clamping blocks 10 is arc-shaped, so that the two rollers are positioned on the same horizontal straight line, and can cover can generate an anticlockwise rotating force when the rollers clamp the can cover, the bottom of clamp splice 10 is seted up and is had the mounting groove corresponding with cutting knife 11, and the inside of mounting groove is rotated and is connected with cutting knife 11, and the cutting edge department of cutting knife 11 is provided with the sawtooth, improves the cutting effect.

A gear 12 is engaged between the two racks 9, when the gear 12 rotates clockwise, the two clamping blocks 10 are closed tightly, when the gear 12 rotates anticlockwise, the two clamping blocks 10 are opened tightly, the gear 12 extends to the inner side of the rotating sleeve 6, only the part of the gear 12, which is positioned at the bottom of the fixed rotating disc 7, is provided with teeth, the two sides of the top of the rotating sleeve 6 are provided with clamping grooves 13, the bottom wall of each clamping groove 13 is provided with an inclined plane for clamping a clamping rod 18, the top of the gear 12 is welded with an adjusting shaft 14, the adjusting shaft 14 is inserted in the rotating sleeve 6, the top of the adjusting shaft 14 is provided with a slot 15, the depth of the slot 15 is smaller than the length of a screw rod 19, the inner side of the slot 15 is welded with two fixing rods 16, the fixing rods 16 extend into screw grooves of the screw rod 19, the two sides of the top of the adjusting shaft 14 are provided with rotating grooves 17, the clamping rod 18 is fixed in the rotating grooves 17 through damping shafts, so that the angle of the clamping rod 18 can be conveniently adjusted, the screw rod 19 is inserted in the slot 15, the top of the screw rod 19 is fixedly connected with a handle, so that the screw rod 19 can be conveniently pulled down.

When opening the iron can, according to can bore size earlier, stir card pole 18 upwards and make it break away from draw-in groove 13, drive regulating spindle 14 through card pole 18 and rotate, regulating spindle 14 passes through gear 12 and drives two racks 9 and slide in slide 8, makes the cutting knife 11 on two clamp splice 10 remove to suitable position, puts the device on the can again, makes fixed cover 1 sticis on the border at can top.

The clamping rod 18 is clamped into the clamping groove 13, the adjusting shaft 14 and the rotating sleeve 6 are fixed together, the screw rod 19 is pressed downwards through the handle, and the two fixing rods 16 are positioned in the screw grooves of the screw rod 19, so when the screw rod 19 is vertically pressed downwards, the two fixing rods 16 need to slide in the screw grooves, the fixing rods 16 drive the rotating sleeve 6 to rotate around the screw rod 19 through the adjusting shaft 14, and the rotating sleeve 6 drives the rotating disc 7 to rotate.

The screw rod 19 is pressed downwards, because friction force exists between the fixed rod 16 and the screw rod 19, the fixed rod 16, the adjusting shaft 14 and the rotating sleeve 6 are pressed downwards when rotating around the screw rod 19, the adjusting shaft 14 and the rotating sleeve 6 move downwards, the rotating sleeve 6 presses the spring 3 to move downwards a little distance along the movable groove 2 through the movable block 4, and the cutting knife 11 at the bottom of the rotary disc 7 is tightly attached to the top of the can.

Thus, when the rotary table 7 rotates, the cutting knife 11 rolls on the iron sheet at the top of the can to cut off the top cover of the can, then the clamping rod 18 is shifted upwards again to be separated from the clamping groove 13, the screw rod 19 has a downward force under the influence of gravity, therefore, according to the principle, the adjusting shaft 14 and the gear 12 both receive a clockwise rotating force, the two clamping blocks 10 generate a relative resultant force through the rack 9, and when the fixed sleeve 1 is held and lifted upwards, the two cutting knives 11 clamp the cut top cover of the can to take out the top cover of the can.

When the glass bottle can is opened, the clamping rod 18 is firstly shifted upwards to be separated from the clamping groove 13, then the can cover is placed between the two clamping blocks 10, the screw rod 19 is pressed downwards to tighten the clamping blocks 10, the roller is tightly attached to the can cover, the screw rod 19 is continuously pressed downwards, and when the tightening force between the two roller wheels is greater than the friction force, an anticlockwise rotating force is generated to unscrew the can cover.
