The gap 2b can be designed to have a suitable size according to the size of the load, so that the load cannot directly fall out of the gap 2 b.

Moreover, the load holding barrel 2 is also provided with a load detector 22 for detecting whether the load is thrown out or not, and the functionality of the device is enhanced. Specifically, the load detector 22 is a photoelectric sensor, and includes a signal emitter 221 and a signal receiver 222 respectively disposed at two sides of the load accommodating barrel 2, the signal emitter 221 and the signal receiver 222 are disposed oppositely, the load accommodating barrel 2 is provided with two signal passing holes, and the two signal passing holes respectively correspond to positions where the signal emitter 221 and the signal receiver 222 are located. If the load in the load receiving tub 2 is thrown, the infrared rays emitted from the signal emitter 221 pass through the two signal passing holes and are received by the signal receiver 222. If the load receiving tub 2 has a load therein, the infrared rays emitted from the signal emitter 221 are blocked by the load. Whether the load is thrown is detected by whether the load blocks the infrared rays emitted from the signal emitter 221, that is, the signal receiver 222 cannot receive the infrared rays.

The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and the technical effects of the present invention should be all included in the protection scope of the present invention as long as the technical effects are achieved by any of the same or similar means.
