The invention relates to a novel trimming machine manipulation brake crank which includes a base (1), a cover (3), an operation handle (2), an operation handle torsion spring (8), a stop ring (4), a stop ring torsion spring (9), a stop ring buffer ring (10), a brake steel wire (5) and a steel wire jacket (6). The base (1) and the cover (3) are arranged in a front and back involution way; an operation groove (13) of the operation handle is arranged in the middle of the top of the involution part of the base (1) and the cover (3); the handle part of the operation handle (2) extends out of the cavity through the operation groove (13) of the operation handle, a steel wire jacket penetrating hole (14) is arranged on the left side of the involution part of the base (1) and the cover (3), the steel wire jacket (6) penetrates into the cavity formed by the base (1) and the cover (3), while the brake steel wire (5) penetrates into the cavity from the steel wire jacket (6). An installation column (1.3) of the operation handle is convexly arranged in the center of the base (1), the stop ring (4) and a locating pin shaft (1.6) are arranged on the right side of the base (1) and the cover (3), the stop ting torsion spring (9) is sheathed on the stop ring (4), and the stop ring buffer ring (10) is sheathed on the locating pin shaft (1.6). The manipulation brake crank has simple and compact structure, convenient operation and high sensitivity.
Description
(1) Technical field [0001] The invention relates to a trimming machine, in particular to a novel trimming machine operating brake handle. It belongs to the technical field of trimming machinery. (2) Background technology [0002] Before the present invention is made, between the base and the cover of traditional novel edge trimmer manipulation brake lever, be fixedly connected with some set screws. The positioning between the handle and the base is carried out by several positioning files. There is no stop buffer ring next to the stop ring, and the buffer effect is played by springs and the like. Its structure is relatively complicated, the connection is relatively cumbersome, and the manipulation sensitivity is not high. (3) Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, provide a kind of simple in structure, compact, easy to operate and high sensitivity novel edge trimmer control brake handle. [000...
