Abstract

The invention discloses a tractor capable of sending out an overload warning. The tractor capable of sending out the overload warning comprises a housing, a fixing hook and a moving hook, wherein a first hanging ring and a sliding chute is arranged in the housing, a gear rack is installed on one side wall of the housing, a wire winding portion is arranged on the other side wall of the housing, a gear matched with the gear rack in engagement mode is connected with the gear rack, the gear is arranged on a sliding block in rotation mode, a second hanging ring, a rotating ring and a positioning block are arranged on the sliding block, the positioning block is arranged in the sliding chute in sliding mode, a spring is arranged between the first hanging ring and the second hanging ring, a round dial plate is fixedly connected with the sliding block, a scale mark, a first contact point and a second contact point are arranged on the round dial plate, the gear is fixedly connected with a rotation body, a pointer is arranged on the rotation body, a contact blade is arranged on the pointer, a fixed pulley and a wire outlet are arranged at the bottom of the housing, and a battery portion is arranged on the housing. Compared with the prior art, the tractor capable of sending out the overload warning is simple in structure and low in manufacturing cost, can display pulling force applied to a cable, and has a warning function, and furthermore can send out the overload warning so as to remind a user to be careful when the pulling force is overlarge.

Description

Technical field [0001] The invention belongs to the field of automobile tractors, and in particular relates to an overload warning tractor. Background technique [0002] Nowadays, cars have become a kind of transportation that has become more and more popular for human travel. When a car breaks down, most of them will ask friends or other vehicle drivers to support nearby, usually using simple nylon rope or other materials. Rope towing, commonly known as soft towing. Soft towing often generates instantaneous huge force due to the start or sudden acceleration of the tractor. This is easy to pull the cable, which will cause unexpected consequences. Summary of the invention [0003] In view of the deficiencies in the prior art, the present invention provides an overload warning tractor, which has a simple structure and low manufacturing cost, can display the tensile force of the cable, and has an alarm function. When the tensile force is too large, an alarm can be issued. Remind...
