The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of unmanned plane actuator head, comprise actuator axle 6, actuator head, rubber coating 7 and car bonnet 8, described actuator axle, actuator head, rubber coating and car bonnet coaxially connect successively, start one end that axial organ is coaxially packed in actuator head, the other end of this actuator head press-fits rubber coating, this rubber coating inside is shaped with taper sheath spring cylinder, this taper elasticity sleeve set is fixed on the end of car bonnet, actuator axle drives the rotation of actuator head, actuator head drives resilient sleeve, and resilient sleeve is by frictional force drives car bonnet synchronous rotary.
The innovative point of present patent application is:
The structure of described actuator head is as shown in accompanying drawing 1 to 5, comprise adapter sleeve shell 3, actuator connection pipe 1, axis hole 4, jackscrew 5 and chute 2, adapter sleeve shell is the cylinder barrel shaped structure that axial one end is shaped with coaxial blind hole, this adapter sleeve other end end face is coaxially fixedly mounted with or is shaped with an actuator connection pipe, this actuator connection pipe is coaxially shaped with an axis hole for being connected with actuator axle, the actuator connection pipe outer wall of this axis hole one side is radially provided with a jackscrew, the sphere of this jackscrew is fitted in a side of actuator axle, for the fixing axial location of actuator axle before engine starting,
