[0016] In the diagram, 1 is the broom handle; 2 is the brush holder; 2a is the connecting part; 3 is the connecting seat; 3a is the hinge part; 4 is the steel ball; 5 is the limiting groove; 6 is the spring; and 7 is the spring seat. Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-2As shown, this utility model discloses a rotatable broom, including a broom handle 1 and a brush holder 2. A connecting seat 3 is provided between the broom handle 1 and the brush holder 2. The brush holder 2 is mounted on the connecting seat 3 and can rotate. The broom handle 1 is detachably mounted on the connecting seat 3. A limiting structure for the rotation of the brush holder 2 on the connecting seat 3 is provided between the brush holder 2 and the connecting seat 3. The limiting structure includes a steel ball 4 provided on the connecting seat 3 and a plurality of limiting grooves 5 provided on the brush holder 2. When the brush holder 2 rotates on the connecting seat 3, the steel ball 4 falls into the corresponding limiting groove 5 on the brush holder 2 for rotation limitation.

[0019] Specifically, the broom base 2 and the broom handle 1 are rotatably connected by a connecting seat 3. During use, the angle of the broom base 2 can be adjusted according to needs, which can not only adapt to the cleaning of the ground, but also to the cleaning of walls or corners, effectively improving the practicality of the broom.

[0020] like Figure 1 and Figure 2 As shown, this utility model discloses a rotatable broom, wherein the brush holder 2 has a circular connecting part 2a, and the connecting seat 3 is provided with a hinge part 3a with a downward-facing notch. The circular connecting part 2a of the brush holder 2 is assembled in the hinge part 3a of the connecting seat 3 and is hinged by a pin.

[0021] Specifically, when the circular connecting part 2a of the brush holder 2 is hinged and rotated in the hinge part 3a of the connecting seat 3, the outer edge of the circular connecting part 2a of the brush holder 2 is adjacent to the top plate of the recess of the hinge part 3a of the connecting seat 3.

[0022] The limiting grooves 5 are distributed on the outer edge of the circular connecting part 2a of the brush holder 2 and are spaced apart along the circumferential direction of the circular connecting part 2a.

[0023] Specifically, five limiting grooves 5 are provided on the outer edge of the circular connecting part 2a of the brush holder 2, with two adjacent limiting grooves 5 spaced apart.

[0024] A through hole is provided on the top plate of the recess of the hinge part 3a of the connecting seat 3. The steel ball 4 is disposed in the through hole and part of the steel ball 4 passes through the through hole and is located in the recess of the hinge part 3a on the connecting seat 3.

[0025] Specifically, the function of the steel ball 4, which partially passes through the through hole and is located in the recess of the hinge portion 3a on the connecting seat 3, is that the portion of the steel ball 4 is located in the recess of the hinge portion 3a to correspond and lock with the limiting groove 5 of the circular connecting portion 2a. When the connecting seat 3 and the circular connecting portion 2a rotate, the steel ball 4 is rotated and limited in the middle.

[0026] The connecting seat 3 is a hollow cylindrical structure. A spring 6 is installed inside the connecting seat 3. The spring 6 acts elastically on the steel ball 4, causing the steel ball 4 to elastically abut against the through hole in the top plate.

[0027] Specifically, the steel ball 4 can be displaced and adjusted by the elastic resistance of the spring 6, making it convenient to use.

[0028] A spring seat 7 is provided inside the connecting seat 3, and a positioning rod 8 is provided on the spring seat 7. The spring 6 is sleeved on the positioning rod 8 on the spring seat 7.

[0029] Specifically, during the spiral advance and spiral retraction of the broom handle 1, the synchronous rotation and lifting of the spring seat 7 are ensured. The spring 6, which is sleeved on the positioning rod 8 on the spring seat 7, can effectively prevent the spring 6 from being displaced, twisted, or deformed when it is performing elastic resistance.

[0030] The outer wall of the spring seat 7 is provided with an external thread, and the inner wall of the connecting seat 3 is provided with an internal thread. The external thread of the spring seat 7 is screwed onto the internal thread of the connecting seat 3.

[0031] Specifically, the purpose of this setting is to effectively adjust the axial displacement of the spring seat 7 in the connecting seat 3 through the helical engagement of the external thread of the spring seat 7 and the internal thread of the connecting seat 3, thereby further adjusting the elastic force of the spring 6.

[0032] In practice, when it is necessary to adjust the angle of the brush holder 2, the brush holder 2 is manually rotated. The rotation of the brush holder 2 drives the connecting part 2a to rotate, and the steel ball 4 is given a radial thrust through the limiting groove 5, causing the steel ball 4 to disengage from the limiting groove 5. At this time, the spring 6 is in a compressed state, and the brush holder 2 continues to rotate. When the next limiting groove 5 is aligned with the position of the steel ball 4, the spring 6 squeezes the steel ball 4 to move into the limiting groove 5. The above steps are repeated to complete the angle adjustment of the brush holder 2. The angle adjustment of the brush holder 2 is convenient and improves the practicality of the broom.
