Further include that the elastic thrust device in the screw side being used to that screw to be pushed to travel forward is set, and/or is arranged in the silk
Female other side is for pulling the elastic tension apparatus that screw travels forward.
Wherein, the elastic thrust device includes compression spring, and the compression spring sleeve is set on the lead screw of the screw side.
Wherein, the elastic tension apparatus includes tension spring, and the tension spring is sheathed on the lead screw of the screw other side.
Wherein, the U-shaped setting of the holder, and be provided with and be used for and the screw both end phase on the two side of the holder
The bearing of cooperation.
Wherein, one end of the lead screw is connected by shaft coupling with the drive shaft of the rotary drive mechanism.
Wherein, the rotary drive mechanism includes motor and the gearbox that is connected with the drive shaft of the motor, described
The main shaft of gearbox is connected with one end of the lead screw by the shaft coupling.
Wherein, the other side of the screw is provided with the push rod for pushing load to travel forward.
Wherein, the load is the piston rod being arranged in the push rod end.
Beneficial effects of the present invention：The present invention includes lead screw and the matched screw of the lead screw and the screw both end
Matched holder and it is arranged and is used to drive the rotary drive mechanism of lead screw rotation in described lead screw one end, further includes
The elastic thrust device in the screw side being used to that screw to be pushed to travel forward is set, and/or is arranged another in the screw
Side is for pulling the elastic tension apparatus that screw travels forward.When rotary drive mechanism driving lead screw rotation, it is arranged in lead screw
On screw under the action of elastic thrust device and/or elastic tension apparatus, it is negative when travelling forward will effectively to reduce screw
Power is carried, and then effectively reduces the power consumption of rotary drive mechanism, the present invention can effectively reduce the power consumption of rotary drive mechanism, increase
Load thrust.
