In order to achieve the above object, the utility model uses technical solution below：
The rotation that a kind of ellipse release shaft includes the interconnecting piece being connected with the handle that declutches and is connected with the interconnecting piece
The cross section in portion, the rotation section is ellipse.
Preferably, the ratio between the short axle of the ellipse of the rotation cross section and long axis are 1:2-1:3.
It is further preferred that the ratio between the short axle of the ellipse of the rotation cross section and long axis are 1:2.7.
Preferably, positioning port and limiting slot are additionally provided between the interconnecting piece and the rotation section.
Preferably, the connecting hole being connected with the handle that declutches is additionally provided on the interconnecting piece.
The utility model additionally provides a kind of drum brake, including the handle that declutches, cylinder, positioned at the cylinder both ends
Quiet core, the coil in the cylinder and dynamic core and the release shaft being connected with the handle that declutches, the release shaft turn
Between the dynamic core, the release shaft is oval release shaft as described above in dynamic portion.
Preferably, be provided on the cylinder with the matched positioning device of the positioning port and with the limiting slot phase
The limiting device of cooperation.
It is further preferred that the limiting device include the elastic component being connect with the cylinder and positioned at the elastic component with
Between limiting slot and with the matched ball of the limiting slot.
Compared with prior art, the utility model is beneficial in that：The oval release shaft tradition of the utility model
Release shaft, the part contacted with dynamic core use cambered surface, avoid the case where causing cutting to armature component when declutching manually, solution
It has determined release shaft stuck phenomenon so that the operation of brake is more safe and reliable.

Wherein：Release shaft -1, interconnecting piece -11, connecting hole -12, positioning port -13, limiting slot -14, rotation section -15 are declutched
Handle -2, cylinder -3, quiet core -4, coil -5 move core -6, elastic component -71, ball -72.
Specific implementation mode
The utility model preferred embodiment is described in detail below in conjunction with the accompanying drawings.
As shown in Figs 1-4, the utility model additionally provides a kind of drum brake, including the handle 2 that declutches, cylinder 3, is located at
The quiet core 4 at 3 both ends of cylinder, 3 coil 5 and dynamic core 6 and the release shaft 1 being connected with the handle 2 that declutches in cylinder, release shaft
1 is located between two dynamic cores 6.
Release shaft 1 includes the interconnecting piece 11 being connected with the handle 2 that declutches and the rotation section 15 being connected with interconnecting piece 11, rotation
The cross section in portion 15 is ellipse, i.e., the release shaft 1 in the present embodiment is oval release shaft 1.
The ratio between the short axle of the ellipse of 15 cross section of rotation section and long axis are 1:2-1:3, the preferred rotation section of the present embodiment 15
The ratio between the short axle of the ellipse of cross section and long axis are 1:2.7.
As shown in Fig. 2, the matched connection in 2 lower end of handle that is additionally provided with and declutches in the present embodiment, on interconnecting piece 11
The lower end in hole 12, the handle 2 that declutches passes through connecting hole 12, then runs through the lower end for the handle 2 that declutches with bolt, and will declutch handle 2
It is connected with release shaft 1.
It is additionally provided with positioning port 13 and limiting slot 14 between interconnecting piece 11 and rotation section 15, is provided with and positions on cylinder 1
Mouthful 13 matched positioning devices and with 14 matched limiting device of limiting slot.As shown in Fig. 2, the positioning in the present embodiment
Device is the matched retainer plate of positioning port, and limiting device includes the elastic component 71 connect with cylinder 3 and positioned at elastic component 71
Between limiting slot 14 and with 14 matched ball 72 of limiting slot, with ensure declutch handle rotation drive release shaft rotation when not
The offset of release shaft position can be brought.Elastic component 71 in the present embodiment is and 72 matched spring of ball.
The course of work of the drum brake of the utility model described briefly below when declutching：
Under brake state, the length direction of rotation section 15 connects with two pieces of dynamic cores 6 on oval release shaft 1
It touches.When needing to declutch manually, the handle 2 that declutches is rotated, and then oval release shaft 1 is driven to rotate, rotation section 11, which drives, to be rotated
Portion 15 rotates, and the part that rotation section 15 is contacted with dynamic core 6 gradually becomes its width direction by the length direction of rotation section 15, two pieces
It moves the distance between core 6 gradually to increase, finally dynamic core 6 is ejected outward, completes operation of declutching.Due to what is be in contact with dynamic core 6
The length direction of rotation section 15 causes to cut when avoiding manual declutch to being that arc is excessive when width direction transition to armature component
The case where cutting solves release shaft stuck phenomenon so that brake is more safe and reliable when using.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this,
It is all according to equivalent change or modification made by the spirit of the present invention essence, should all cover the scope of protection of the utility model it
