The utility model discloses a wire spool device for stabilizing the wire direction of a spring machine, and relates to the technical field of spring machines, the wire spool device comprises a wire spool assembly, a Z-axis adjusting assembly, a rotation adjusting assembly, a Y-axis adjusting assembly and an assembly plate, the Y-axis adjusting assembly is fixedly arranged on the assembly plate, the rotation adjusting assembly is arranged on the Y-axis adjusting assembly, and the Z-axis adjusting assembly is fixedly arranged on the Y-axis adjusting assembly. The Z-axis adjusting assembly is arranged on the rotary adjusting assembly, and the wire spool assembly is arranged on the Z-axis adjusting assembly; the wire spool assembly comprises a wire guide block, a fixing disc, a wire spool and a plurality of wire guide assemblies, a plurality of first adjusting grooves are formed in the fixing disc, the first adjusting grooves are arranged in a circumferential array with the center of the fixing disc as the circle center, and one wire guide assembly is arranged in each first adjusting groove; according to the utility model, the wire entering the spring machine is more stable and does not swing, the processing precision of the spring machine is improved to a certain extent, and the yield of finished springs is improved.

The application discloses a traffic cone pretreatment device automatic folding and unfolding system, a folding and unfolding vehicle and a folding and unfolding method. The automatic folding and unfolding system comprises a guide rail base, a guide rail frame, a pretreatment device, an electric push rod I and an electric push rod II. The guide rail base is connected with a vehicle frame and is installed on a sliding rail of the guide rail frame and slides up and down through the electric push rod I. A hinged base II of the guide rail frame is hinged with the pretreatment device, a hinged base I is hinged with the electric push rod II, the other end of the electric push rod II is hinged with the first guide rod end of the pretreatment device, the electric push rod II drives the pretreatment device to swing, the automatic folding and unfolding system of the pretreatment device is installed on the side of the vehicle and is wholly stored under the vehicle frame during driving, so that the system does not exceed the width of the vehicle. The multi-stage rotary support limiting structure can effectively reduce the horizontal folding and unfolding space of the device, realize a large telescopic stroke, ensure the stability of the included angle between the guide rod and the first guide rod and prevent swinging. The electromagnetic lock locking mechanism ensures sufficient ground clearance during driving.

The invention discloses an adjustable gearbox bearing puller which comprises a main rod, a sliding hammer, a pressing sleeve and a claw assembly. One end of the main rod is in threaded connection with the pressing sleeve and the claw assembly in sequence; the sliding weight is arranged on the main rod in a sliding and sleeving mode and detachably connected. The opening and closing of the hook claws are independently adjusted through the independent pressing sleeve, the hook claws do not deviate after being positioned and can be self-locked after being locked, the hook claws do not loosen or pop up in the pulling-out process, safety is remarkably improved, clamping is firm, and safety and reliability are achieved.
