Preferably, the living hinge support has two guide shaft holes arranged at intervals, so that the cam shaft can move between the two guide shaft holes in the vertical direction.
Preferably, the camshaft is mounted between the two guide shaft holes through a key connection, so that the clamping arm can rotate within 180 degrees from top to bottom.
Preferably, both cams of the cam shaft have two symmetrical side edges in parallel relation to the extending direction of the clamp arm, so that the clamp arm can only rotate to two fixed angles vertically upwards or vertically downwards.
Preferably, powerful magnets are arranged at the tail ends of the clamping arms and the corresponding attachment objects.
Preferably, the strong magnet is a rubidium magnet type strong magnet.
In the embodiment of the invention, the traditional attachment object is fixedly connected with the clamp arm, the clamp arm mechanism is in movable hinge connection, and the clamp arm can rotate at a large angle by taking a hinge as a center, so that the situation that a user clamps too many too thick objects to cause the clamp arm to be broken or deformed is avoided; the tail ends of the clamping arms and the corresponding attachment objects are provided with powerful magnets which can provide sufficient friction in a clamping state so as to prevent the clamping arm mechanisms from falling off; the arm clamping mechanism has the anti-breaking property, so that arm clamping fragments are not easily generated in the using process of the young children, the possibility that the children swallow tiny objects is further reduced, the using safety of products is improved, and the arm clamping mechanism is also suitable for other objects with the arm clamping mechanism.

Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1-6, fig. 1 is a schematic view of a movable hinge type anti-break arm 5 mechanism according to the present invention, which includes an attached object 1, a cam shaft 2, a movable hinge support 3, a fastening structure 4, an arm 5, a telescopic mechanism 6, and a strong magnet 7; the activity hinge support 3 sets up block 5 mechanism tops of arm, the upper end of block arm 5 is passed through the camshaft with 3 normal running fit of activity hinge support, fastening structure 4 sets up 3 downside of activity hinge support and with depend on 1 fixed connection of object, telescopic machanism 6 sets up block arm 5 is kept away from the one end of camshaft, powerful magnet 7 sets up telescopic machanism 6 is kept away from the one end of block arm 5.
As shown in fig. 2, when the clamp arm 5 works and is in a clamping state, the camshaft is positioned at the upper part of the living hinge support 3, and the clamp arm 5 is in a vertical state under the action of the fastening mechanism, and the strong magnet 7 arranged at the tail end of the clamp arm 5 and corresponding attached object 1 can provide sufficient friction force to prevent the clamped object from falling off in the clamping state; as shown in fig. 3, when the latch arm 5 is in the non-clamping operating state, the cam shaft is located at the lower portion of the living hinge support 3, and the latch arm 5 can be retracted to a length short enough to prevent the latch arm 5 from extending too much in the non-clamping operating state, and only if the length of the latch arm 5 is small enough, the arm of force of the latch arm 5 is short enough to prevent the latch arm 5 from being broken due to too large moment; as shown in fig. 4, when the user uses an improper use mode, a large force is applied to the clip arm 5, and the clip arm 5 is separated from the constraint of the fastening mechanism by the moment of the clip arm 5 to perform a rotation motion around the hinge.
As for the camshaft, as shown in fig. 6, at both ends of the living hinge support 3, the camshaft may make a rotational motion, and the cam may move to the other end along the guide hole only when the cam direction coincides with the guide hole direction, and may continue to rotate only after reaching the other end; the cam shaft is in key connection with the clamp arm 5, so that the angle of the cam is consistent with that of the clamp arm 5.
