Referring to fig. 1 to 5, a handle provided by an embodiment of the present invention is shown, which includes a housing 1 and a rotor 2. Wherein, the shell 1 is provided with a gap 11, specifically, the shell 1 is substantially in a flat and long strip shape, the gap 11 is provided at one side of the shell 1 in the width direction, and the gap 11 can be directly used for opening a beer bottle cap when necessary. The rotating body 2 is positioned in the shell 1 and is rotatably connected with the shell 1, at least two functional parts are arranged in the circumferential direction of the rotating body 2, each functional part can expose the notch 11 in an alternative mode along with the rotation of the rotating body 2, and the height difference between the notch 11 and the shell 1 can be filled when at least one functional part is exposed out of the notch 11; when any functional part is exposed out of the notch 11, the rotating body 2 can be locked or unlocked with the shell 1.

In the above arrangement, since there are at least two functional portions, the function of the handle can be increased, that is, the function of holding the handle itself can be realized, and other functions can be realized by the functional portions. In addition, because at least one functional part can fill and level up the difference in height between breach 11 and the casing 1 when exposing breach 11, so the utility model discloses a handle can prevent that the user from going into breach 11 with the finger card when using, avoids causing the potential safety hazard. When any functional part is exposed out of the notch 11, the rotating body 2 can be locked or unlocked with the shell 1, so that the use reliability can be ensured, and the influence on normal use caused by the rotation of each functional part in use is avoided.

In order to further explain the utility model discloses a how avoid the potential safety hazard, now take the functional part to have two as the example, one of them functional part is made the bayonet type of opening the beer bottle, and another functional part is made flat-plate-like, and flat-plate-like edge is unanimous with the edge orbit of casing 1, so the user can expose flat-plate-like functional part breach 11 when need not opening the beer bottle to fill out the difference in height between breach 11 and the casing 1 to avoid user's finger card to go into in breach 11.

Of course, the number of the functional parts can be increased according to the requirement, for example, the number of the functional parts can be three, one of the functional parts is in a bayonet shape for opening beer bottles, the other functional part is in a screwdriver shape for screwing, the third functional part is in a flat plate shape, and the flat plate-shaped edge is consistent with the edge track of the shell 1.

In a preferred embodiment, at least one of the functional parts is a bayonet 21 for opening the closure. That is, the utility model has at least one bayonet 21 for opening the beer bottle cap in addition to at least one functional part for filling the height difference between the gap 11 and the shell 1.

Preferably, referring to fig. 6-7, the housing 1 is provided with an unlocking button, the unlocking button includes a button portion 17 located outside the housing 1 and a clamping post 18 located inside the housing 1, the button portion 17 can control the clamping post 18 to clamp or release the clamping with the rotating body 2, when the clamping post clamps with the rotating body 2, the rotating body 2 is locked with the housing 1, that is, the rotating body 2 and the housing 1 cannot rotate relatively, and when the clamping post releases the clamping with the rotating body 2, the rotating body 2 is unlocked with the housing 1, that is, the rotating body 2 and the housing 1 can rotate relatively.

Specifically, the rotating body 2 is provided with the same number of clamping holes 24 corresponding to the functional parts one by one, and the clamping posts 18 can extend into the corresponding clamping holes 24 and withdraw from the corresponding clamping holes 24. When the clamping column 18 extends into the corresponding clamping hole 24, the rotating body 2 and the shell 1 can not rotate relatively, and when the clamping column 18 exits from the corresponding clamping hole 24, the rotating body 2 and the shell 1 can rotate relatively.

Referring to fig. 7, the button 17 has an elastic hook 171, and when the elastic hook 171 of the button 17 is pressed leftward, the elastic hook 171 is disengaged from the housing 1, and at this time, the button 17 is pulled upward, thereby moving the latch 18 out of the latch hole 24. On the contrary, when the locking post 18 needs to be inserted into the locking hole 24, only the button portion 17 needs to be pushed downward, at this time, the elastic hook 171 is locked with the housing 1, and the locking post 18 extends into the corresponding locking hole 24 along with the downward pushing of the button portion 17.

Of course, in addition to the above-described manner, the button portion 17 can be engaged with the catch 18 in the same manner as the cap of a ballpoint pen is engaged with a refill, and when the button portion 17 is pressed, the catch 18 moves downward into the catch hole 24, and when the button portion 17 is pressed again, the catch 18 moves upward to exit the catch hole 24.

Preferably, referring to fig. 3-5, the number of the functional parts is two, one of the functional parts is made into a bayonet shape for opening beer bottles, the other functional part is made into a flat plate shape, the edge of the flat plate shape is consistent with the edge track of the shell 1, a limiting column 22 and two elastic convex parts 23 are arranged on the rotating body 2 along the circumferential direction, and the two convex parts 23 are respectively arranged at two sides of the limiting column 22; two clamping grooves 14 are formed in the shell 1, and the two clamping grooves 14 are arranged along the circumferential direction of the rotating body 2; when one functional part is exposed out of the notch 11, one protruding part 23 is suitable for being clamped into one clamping groove 14, and the side, where the protruding part 23 is located, of the limiting column 22 is suitable for being abutted against the outer wall of the clamping groove 14; when the other functional part is exposed out of the notch 11, the other protruding part 23 is suitable for being clamped into the other clamping groove 14, and at the moment, the side of the limiting column 22 where the other protruding part 23 is located is suitable for being abutted against the outer wall of the other clamping groove 14. By the abutting of the limiting column 22 and the outer wall of the clamping groove 14, the excessive rotation of the rotating body 2 along one direction can be avoided, and the use reliability can be ensured. And the lug boss 23 has elasticity, so that a user can forcibly rotate the rotating body 2 in the opposite direction to make the lug boss 23 come out of the catch 14 so as to unlock.

Preferably, the housing 1 is further provided with a socket 15, and the socket 15 is used for accommodating a pull ring of a pop can. For a user who has too long nails or wears fingernails, the user can easily pull up the pull ring of the can through the insertion opening 15 of the case 1, thereby opening the can.
