Spreader

This creation is related to the spreader, and in particular to a spreader for replacing the brake caliper for disassembly and assembly applications.

Press, the current brake cylinder will gradually become convex as the brake pads become thinner. When the brake pads wear to a certain extent and must be replaced, the pump shaft must be rotated and pressurized to restore the original. The distance can be replaced by a new brake car. The first known car repairs are related to the brakes, brakes, pistons, etc., which need to be disassembled on both sides of the axial side, usually through the board and the push plate. The tools are respectively abutted against the end face of the piston, and by rotating the threaded rod, the pedal and the push plate can be pushed to facilitate the replacement.

Please refer to the Republic of China Patent No. M407134 "Brake Cylinder Traction Tool Structure", which comprises a gun-shaped seat, a clamping portion and a main shaft portion, wherein the gun-shaped seat is a hollow main cylinder The side is provided with a fixed handle and a trigger handle is disposed, the flap of the upper end of the trigger handle enters the main cylinder, and the clamping portion is installed in the main cylinder and can be elastically advanced and retracted, and includes a tube inner front tube and a first clamping block group. a second clamping block group and a positioning cylinder, wherein the left and right sides of the front cylinder are clamped by the airfoil and can be driven, and the corresponding contact surface of the front inner cylinder and the first clamping block has inner and outer corresponding taper, and the second clamping block group Then, the positioning cylinder has a corresponding taper inside and outside, and the outer side of the main cylinder is exposed with a buckle that is combined with the positioning cylinder. The main shaft of the main shaft portion penetrates the main cylinder and the clamping portion, so that the first and second clamping blocks can engage the outer side of the main shaft; The front handle of the pipe is moved forward, and the inner and outer taper are combined to form an inner and outer taper fit, and the inner diameter of the first clamp block is controlled to be engaged to engage the main shaft, so that the main shaft can be pushed by a small distance with the trigger handle each time, second The clamping block bites the main shaft to provide a back-stop effect to prevent back-off And quickly replace the brakes to make the film.

The above is a brake disassembly aid of a conventional type, but its use is in the form of a grip type structure, so it is more suitable to operate in a one-hand grip manner, but it is often necessary to use a grip to reach the brake caliper. Need to apply considerable force, so it is easy to cause construction workers to exercise In addition, the brake caliper dismounting structure of the grip type is a progressive push-type device of the connecting rod. When the operation stroke is to the end, the release structure must be designed to return to the unpressed state, so The design of the structure is slightly more complicated.

In view of this, the creator has been engaged in the development of related industries for many years, and has in-depth discussions on the problems faced by existing brake disassembly devices, and actively seeks solutions. After long-term research and development, he has finally succeeded in creating A spreader structure, in particular, is a spreader structure applied to a brake caliper disassembly and assembly application, and has the characteristics of simple structure and easy application of force.

The main purpose of this creation is to provide a spreader for replacing the brake caliper disassembly and assembly application, and having the characteristics of simple structure and easy application of force.

In order to achieve the above object, the present invention provides a spreader comprising a built-in seat, a first outer expansion plate, a second outer expansion plate and a transmission unit.
