protrusions 11 can be correspondingly clamped into the limiting grooves 4, if the brake lever switch main body 1, the brake lever main body 2 and the fastening piece 3 deflect due to the reasons that screws are loosened, the screws slide threads occur and violent vibration and the like during the running of a vehicle in a jolt, thereby influence is caused to the control of a user on the brake crank switch, at the moment, a gap is formed between the limiting clamping plate 9 and the internal thread ring 5, the triangular bulge 11 is difficult to be completely clamped inside the limiting groove 4, along with the aggravation of the conditions, the brake crank switch main body 1, the brake crank main body 2 and the fastening piece 3 still have movable deflection, so that the reinforcing screw is not needed or the screw is replaced, the user can adjust and reinforce the brake crank switch main body 1, the brake crank main body 2 and the fastening piece 3 at any time, the trouble of finding tools is avoided, the cost of purchasing parts is also avoided, the adjusting reinforcement is as follows, the user still twists the twisting block 12 to drive the rotating handle 16 to rotate, finally pushes the two limiting clamping plates 9 to be tightly attached to the metal handle 15, the triangular bulge 11 is completely clamped in the inner cavity of the limiting groove 4, and the adjusting reinforcement of the brake crank switch main body 1, the brake crank main body 2 and the fastening piece 3 is realized, the brake crank switch main body 1, the brake crank main body 2 and the fastener 3 are prevented from movably deflecting on the metal handle 15, and meanwhile, the positioning nut 13 needs to be correspondingly adjusted, wherein when the connecting push plate 7 moves towards the direction of the limiting clamping plate 9 under the limitation of the swing tracks of the two limiting clamping plates 9 and the space between the two limiting clamping plates 9, the four movable connecting rods 8 can make reasonable and flexible changes along with the actual moving tracks and the actual conditions without influencing the movement of the connecting push plate 7 and the limiting clamping plates 9, the prior art is described above, and too much description is omitted, so the technical scheme adopts the technical scheme that the two limiting clamping plates 9 are arranged in the fastener 3 and matched with the triangular protrusions 11 on the inner sides of the limiting clamping plates 9, and the limiting grooves 4 on the metal handle 15 are combined into a buckling structure which is firmly buckled on the metal handle 15, thereby can restrict metal handle 15 and rotate in the inside of brake lever main part 2 and fastener 3, that is to say restriction brake lever switch main part 1, brake lever main part 2 and fastener 3 rotate on metal handle 15's surface, make the brake lever switch also be difficult for appearing deflecting even in violent vibrations, and even fastening screw appears not hard up also can adjust the laminating degree of spacing cardboard 9 and metal handle 15 through rotating threaded pin 6, thereby promote the compactness of spacing cardboard 9 and metal handle 15 lock joint, thereby guarantee the compactness and the fastness of brake lever switch installation, guarantee that the brake lever switch is located initial installation position all the time, avoid appearing the angular deviation, guarantee that the user can accurate operation brake lever switch, also can promote user's use travelling comfort, avoid the user to appear "the hand and foot is unforgettable" condition in the operation in-process of riding, thereby promote driving safety, it explains that, set nut 13 is in the in-process of screwing up, can form an outward pulling force to threaded pin 6, and threaded pin 6 is with internal thread 5 threaded connection, consequently under set nut 13 is difficult to realize the internal thread 6 of internal thread of internal thread 6, make internal thread 6 internal thread of internal thread 6 fix a position pin 5.

The inside of brake lever switch main part 1 is provided with metal handle 15, metal handle 15 is located the inboard of brake lever main part 2 and fastener 3, the spacing recess 4 with protruding 11 looks adaptations of triangle is seted up to one side that the surface of metal handle 15 is close to fastener 3, metal handle 15 and two spacing cardboard 9 looks adaptations.

Specifically, offer of spacing recess 4 on the metal handle 15 for the spacing cardboard 9 of joint, in the adjustment reinforcement of installation and later stage, the card that the triangle on the spacing cardboard 9 is protruding 11 corresponds is gone into in spacing recess 4, so just can restrict brake lever switch main part 1, brake lever main part 2 and fastener 3 and deflect at the surperficial activity of metal handle 15, thereby guarantee brake lever switch main part 1, the fastness and the stability of brake lever main part 2 and fastener 3.

The surface of the metal handle 15 is sleeved with a rotary handle 16, and the inner side of the rotary handle 16 is integrally provided with a long convex strip 20 matched with the limiting groove 4.

Specifically, the rotation handle 16 is divided into an inner layer structure and an outer layer structure, the inner layer structure is used for installing the fixed rotation handle 16, the deviation of the rotation handle 16 based on the axial angle of the metal handle 15 is avoided, the outer layer structure is used for realizing the normal function of the rotation handle 16, the long raised line 20 is arranged in the inner layer structure, so that the rotation handle 16 can be limited to deflect, the situation that the control force is too large or too small when a user operates and starts a vehicle is avoided, the driving safety of the user is improved, and it needs to be explained that the inner layer rotation handle 16 and the outer layer rotation handle 16 adopt a movable connection mode.

The rotating handle 16 is rotatably installed on the brake crank switch main body 1, the surface of the rotating handle 16 is provided with anti-skid lines, and the rotating handle 16 is sleeved on the metal handle 15.

Specifically, the outer surface of the rotary grip 16 is provided with anti-slip lines, so that when a user holds the rotary grip 16 to work, the friction between the palm and the rotary grip 16 can be increased, and an anti-slip effect is achieved.

The inboard movable mounting of brake lever main part 2 has hand brake lever 17, one side of brake lever main part 2 is run through and is provided with brake cable 19, the one end fixed connection of brake cable 19 is on hand brake lever 17, one side integrated into one piece of brake lever main part 2 is connected with rear-view mirror mount pad 18, the internal thread mounting hole is seted up at the top of rear-view mirror mount pad 18.

Specifically, add on the brake lever main part 2 and be equipped with rear-view mirror mount pad 18, reserve the mounted position for the rear-view mirror for the brake lever switch more conveniently installs the rear-view mirror in subsequent equipment, it is convenient for user's installation work to provide, it needs to explain that, the concrete installation technology of brake cable 19 is prior art, and the text is not explained too much.

The number of the limiting grooves 4 is not less than five, and the limiting grooves 4 are distributed on the surface of the metal grip 15 in a fan shape.

Specifically, the position that spacing recess 4 set up will be located the one side towards fastener 3, and a plurality of spacing recesses 4 are fan-shaped distribution, so two triangle-shaped protruding 11 on the spacing cardboard 9 can be smooth the card go into spacing recess 4 in, realize spacing to the brake lever switch, prevent that the brake lever switch from deflecting.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
