When the user needs to stop the car, the first recess 2041 cooperates with the fixing column 101, so that the brake wrench 2 is in a self-locking state, and there is no need to hold the brake wrench 2 tightly all the time. The structure is simple and easy to use.

[0027] Specifically, the brake wrench 2 includes a first rotating support angle 201, which extends to one end to form a handle position 202, and the first rotating support angle 201 extends upward to the other end to form a second rotating support angle 203, and the second rotating support angle 203 extends toward the handle position 202 to form a sliding position 204, and the first recessed position 2041 is arranged on the sliding position 204, and the handle seat 1 includes a handle position 105, and the handle position 105 is bent downward to form an accommodating position 102, and the accommodating position 102 extends downward to form a first mounting position 103, and a second mounting position 104 is arranged on the side of the accommodating position 102, and a second support position 1021 is arranged in the accommodating position 102, and the fixed column 101 is arranged on the side of the second support position 1021, and the first support position 1022 is arranged below the fixed column 101, and the second rotating support angle 203 is rotatably arranged on the second support position 1021, and the first rotating support angle 201 is rotatably arranged on the first support position 1022.

[0028] A placement hole 205 and a second recess 206 are provided above the first rotating support angle 201, and a first slot 207 is provided between the placement hole 205 and the second recess 206; a second slot 1023 is provided below the second support position 1021, the second slot 1023 is connected to the third slot 1024, and a limiting hole 1025 is provided below the third slot 1024. The first slot 207, the second slot 1023, the third slot 1024 and the limiting hole 1025 are connected to each other, and the placement hole 205 is used to install the round head end of the brake line, and the line end of the brake line passes through the first slot 207, the second slot 1023, the third slot 1024 and the limiting hole 1025 in sequence to extend outward.

[0029] like Figure 3 As shown, when only braking is needed, the handle position 202 is rotated upward, and the second rotating support angle 203 uses the second support position 1021 as a fulcrum to rotate the first rotating support angle 201 in the opposite direction, and the brake operation is achieved by pulling the brake line through the brake wrench 2, such as Figure 4As shown, when parking is required, the handle 202 only needs to be turned downward, and the first rotating support angle 201 takes the first supporting position 1022 as a fulcrum, so that the second rotating support angle 203 rotates in the opposite direction around the inner wall of the accommodation position 102, so that the first concave position 2041 is clamped on the fixing column 101, and the brake wrench 2 pulls the brake line to realize the self-locking operation, as shown in FIG. Figure 5 As shown, when it is necessary to contact the self-locking state, just rotate the handle position 202 upward, and the first rotating support angle 201 uses the first support position 1022 as a fulcrum to allow the second rotating support angle 203 to rotate in the opposite direction around the inner wall of the accommodating position 102, so that the first recessed position 2041 and the fixed column 101 are disengaged from the clamping state, and the second rotating support angle 203 is pressed against the second support position 1021 to achieve the reset of the brake wrench 2.

[0030] The outer wall of the accommodation position 102 is provided with reinforcing ribs 1026, which effectively enhance the strength of the accommodation position 102 and make the handle seat 1 structure more stable.
