Detailed Description
Example 1:
referring to fig. 1-4, a conveniently assembled power-off brake crank comprises a brake crank base 1, a handle 2 and a power-off switch 3, wherein the handle 2 is rotatably connected with the brake crank base 1, and the rotatable connection structure of the handle 2 and the brake crank base 1 is known in the art, so that the details are not repeated herein. One end of the handle 2 extends into the accommodating cavity 11. In addition, the brake lever base 1 is integrally formed of aluminum.
The brake lever base 1 is provided with a receiving cavity 11, and the receiving cavity 11 is provided with a wire outlet hole 12, wherein the wire outlet hole 12 is positioned in the reverse direction of the handle 2 (positioned on the other side of the brake lever base 1). The inner wall of the accommodating cavity 11 is provided with a clamping groove 13. Still be equipped with through-hole 14 on the brake lever base 1, the elastic barrier 4 after fixing with draw-in groove 13 is located the axial direction of through-hole 14, and the setting of through-hole 14, when needs are dismantled, the instrument stretches into in the through-hole 14, changes the deformation state that the elastic barrier 4 was blockked, removes the fixed state that the elastic barrier 4 was blockked 4 and draw-in groove 13, forms the dismantlement.
