However, the key structure in the existing dust collector has some defects, one type is a structure in which each key is independently arranged, a special fixing structure needs to be arranged for each key, the manufacturing cost is high, the assembly process is complex, and the improvement of the production efficiency is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems existing in the prior art, the utility model provides a key assembly and use dust collector of this subassembly can realize two kinds of functions through a set of key assembly, and simple structure, the equipment and the use of being convenient for.

In order to achieve the above purpose, the technical scheme of the utility model has:

a key assembly, comprising: the key comprises a first mounting structure, a second mounting structure, a fixing ring, a key body and a trigger unit;

the first mounting structure is used for fixing the position of the fixing ring;

the fixing ring comprises a ring body provided with an opening and a first cross beam, and the first cross beam stretches across the opening to be connected with two opposite sides of the ring body;

the key body is arranged in the opening through the second mounting structure and comprises a second cross beam which is abutted against the first cross beam; under the action of external force, the key body is positioned at two ends of the second cross beam and can swing within the range limited by the second mounting structure by taking the first cross beam as a fulcrum;

the triggering unit is acted by two ends of the key body to respectively trigger different functions.

There are some defects in the button among the prior art, the utility model provides a button subassembly provides the structure of easily assembling. The first mounting structure is used for mounting and fixing the fixing ring on equipment or machinery needing to use the key assembly; the fixing ring is connected with the key body, so that the whole key assembly forms a relatively complete structure, and can be directly installed and fixed when needing to be installed on equipment or a machine for use; the first crossbeam that spanes the opening on the ring body in the stationary ring has divided into the opening two parts that are used for realizing two kinds of functions respectively, and when the button body was installed among the opening, the second crossbeam on the button body supported and form the oscillating axle that supports button body both ends wobbling on first crossbeam, and when the button body both ends received external force to press respectively, thereby both ends inwards swung respectively and acted on respectively in order to trigger different functions at the unit. More importantly, the first cross beam and the second cross beam in the scheme can ensure that two ends of the key body cannot be pressed down simultaneously, and one function can be realized by only pressing one end of the key body at one time; on the other hand has still considered key assembly often less, is difficult to realize the problem of the operation in shaft hole is filled in to the pivot, adopts first crossbeam and second crossbeam to support wobbling mode and has compared general pivot and shaft hole structure, and is simple more convenient in the installation, can realize fast assembly.
