The placement groove 13 has notches 15 on the left and right sides for fingers to insert. The notches 15 extend from the outer end face of the handheld rod 12 to the bottom of the placement groove 13, making it easy for the user to insert their fingers into the notches 15, grab the brush rod 11 hidden in the placement groove 13, and rotate it into a straight rod structure for the user to use.

[0032] The brush rod 11 is provided with a limiting structure limiting the rotation range between the brush rod 11 and the handheld rod 12, the brush rod 11 is a straight rod structure after being unfolded relative to the handheld rod 12, the limiting structure includes a limiting surface 121 provided on the handheld rod 12 and a bottom surface provided on the brush rod 11, after the brush rod 11 is rotated to the limit relative to the handheld rod 12, the bottom surface of the brush rod 11 contacts the limiting surface 121, which can avoid the brush rod 11 being rotated too much, and the handle 1 is unfolded as a straight rod structure for facilitating the user to use.

[0033] The adapter 16 is protruded on the limiting surface 121, the shaft 162 is protruded outward on both sides of the adapter 16, the rotating groove 111 is upwardly opened on the bottom surface of the brush rod 11, the rotating groove 111 is opened on the outer side to facilitate the adapter 16 to be clamped on the outer side, the sink hole 113 is provided on both sides of the rotating groove 111, so that the shaft 162 is pressed to elastically deform the side wall of the rotating groove 111 and then enters the sink hole 113, so as to realize the rotation connection between the brush rod 11 and the handheld rod 12.

[0034] The limiting structure further includes the clamping belt 112 protruded on the inner side wall of the rotating groove 111, the adapter 16 is provided with the avoiding groove 161 on the back for placing the clamping belt 112 after the brush rod 11 is rotated, the end surface of the clamping belt 112 and the avoiding groove 161 is contacted on the upper side, which further limits the rotation range.

[0035] Specifically, the brush rod 11 and the handheld rod 12 are provided as the rotation connection to realize the folding function of the handle 1, after the brush rod 11 is hidden in the placing groove 13, the overall space is saved, the handle 1 is facilitated to be placed and carried, even to be packed and mailed, and the brush head 2 of the toothbrush is provided as a separate body from the handle 1, the brush head 2 is installed or removed on the handle 1 in a detachable manner, so that the existing disposable balloon toothbrush only needs to replace the brush head 2, without replacing the handle 1 part, which saves the material and the purchase cost of the user.
