[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] See also Figure 1-Figure 5 The handheld electrical appliance with a retractable charging head includes a handheld portion 1, a torsion piece 2 and a joint portion 3. A linkage structure is provided between the joint portion 3 and the torsion piece 2. The torsion piece 2 can rotate relative to the handheld portion 1 and, through the linkage structure, the head portion 3 can be retracted toward the inside of the handheld portion 1 or extended toward the outside of the handheld portion 1. The user can extend the joint portion 3 outward or retract it inward by rotating the torsion piece 2. The operation is simple, the chance of damage to the joint portion 3 can be reduced, and the overall appearance of the electrical appliance is more beautiful.

[0025] In this embodiment, the handheld electrical appliance may be an earphone charging compartment, which is generally used to store wireless Bluetooth earphones and charge the wireless Bluetooth earphones.

[0026] Furthermore, the linkage structure includes a socket 21 and a connecting rod 4, the socket 21 is arranged at the inner side position of the torsion member 2 corresponding to the hand-held part 1, the connecting rod 4 is connected and fixed to the joint part 3, a protruding block 41 is provided on the outer side of the connecting rod 4, and a guide groove 211 corresponding to the protruding block 41 is provided on the inner side of the socket 21, and the guide groove 211 is spirally arranged along the inner wall of the socket 21. The torsion member 2 makes a circumferential motion relative to the connecting rod 4 to enable the protruding block 41 to slide along the guide groove 211, and the protruding block 41 slides along the guide groove 211 to cause the connecting rod 4 to be received into the socket 21 or extended out of the socket 21, and the receiving of the connecting rod 4 into the socket 21 or extending out of the socket 21 can cause the joint part 3 to be received toward the inner side of the hand-held part 1 or extended toward the outer side of the hand-held part 1.

[0027] Furthermore, two protruding blocks 41 symmetrically arranged in the radial direction are provided on the outer side of the connecting rod 4, and two guide grooves 211 corresponding to the two protruding blocks 41 are provided in the socket 21. The protruding blocks 41 and the guide grooves 211 are connected and matched one by one, so as to further improve the stability of the connecting rod 4 when it is received into the socket 21 or extended out of the socket 21.

[0028] Furthermore, a limiting structure is provided on the hand-held part 1 or the torsion member 2 for limiting the movement of the connecting rod 4 or the joint part 3 toward the inner side of the hand-held part 1. After the joint part 3 is extended out of the outer side of the hand-held part 1, the joint part 3 will not retract into the inner side of the hand-held part 1 due to the plug-in action, thereby ensuring that the user can use the joint part 3 normally.

[0029] Furthermore, the limiting structure includes a shell limiting portion 11 disposed on the handheld portion 1 and a rod limiting portion 42 disposed on the connecting rod 4. The connecting rod 4 extends outward from the insertion hole 21 so that the rod limiting portion 42 squeezes the shell limiting portion 11 to elastically deform, until the rod limiting portion 42 passes through the shell limiting portion 11 to reset the shell limiting portion 11. The shell limiting portion 11 abuts against the rod limiting portion 42 at a position toward the inside of the handheld portion 1. The shell limiting portion 11 cooperates with the rod limiting portion 42 to play a blocking effect when the joint portion 3 is stored inside the handheld portion 1, so that the head joint portion will not retract to the inside of the handheld portion 1 due to the plugging action. When the joint portion 3 needs to be stored inside the handheld portion 1, it is only necessary to increase the twisting force of the torsion member 2, that is, the pulling force generated by the torsion member 2 on the connecting rod 4 is greater than the elastic deformation force of the extrusion block, so that the joint portion 3 can be stored inside the handheld portion 1.

[0030] Furthermore, a limiting rib 12 is provided on the hand-held portion 1, and the limiting rib 12 is arranged along the circumference of the inner wall of the hand-held portion 1. A limiting groove 22 corresponding to the limiting rib 12 is provided on the torsion piece 2. The torsion piece 2 can rotate relative to the hand-held portion 1 so that the limiting rib 12 and the limiting groove 22 are slidably matched. The matching of the limiting rib 12 and the limiting groove 22 can keep the relative axial position of the torsion piece 2 and the hand-held portion 1 unchanged, thereby improving the stability of the torsion piece 2 when rotating relative to the hand-held portion 1.

[0031] Furthermore, a plurality of limiting ribs 12 and limiting grooves 22 are respectively distributed on the hand-held portion 1 and the torsion member 2 . The limiting ribs 12 and the limiting grooves 22 are connected and matched one by one, so as to further improve the stability of the torsion member 2 when rotating relative to the hand-held portion 1 .

[0032] Furthermore, the connector portion 3 is a charging connector, which is a USB charging connector and can be used to charge electrical appliances.

[0033] Furthermore, a handle portion 23 is provided on the outer side of the twisting member 2 corresponding to the hand-held portion 1. The handle portion 23 is extended in the length extension direction of the twisting member 2. The handle portion 23 enables the user to twist the twisting member 2 more easily, further simplifying the user's operation.

[0034] Furthermore, a hanging hole 231 is provided on the handle portion 23 , and the hanging hole 231 passes through the handle portion 23 in a horizontal direction. The hanging hole 231 can be used to hang ornaments or pendants, making the product more beautiful as a whole and more convenient to carry.

[0035] The above embodiments are only preferred embodiments of the present invention, and the present invention may have other embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope set by the claims of this application.
