Mechanical brake structure of pruning scissors

Abstract

The invention discloses a mechanical brake structure of a pair of pruning scissors. The mechanism brake structure comprises a brake rod, the lower end of the brake rod is linked with a brake device, a brake rod return spring is arranged at the lower part of the brake rod, a brake cap is arranged at the upper end of the brake rod, a pull sheath is arranged outside the brake rod, a protruding salient point is arranged in the middle of the upper plane of the pull sheath and props against the lower plane of the brake cap, a microswitch for on of a circuit of the pruning scissors is arranged above the brake cap, a stay rope mechanism is connected on the left side of the pull sheath and is controlled by a switching trigger arranged on a rear handle of the pruning scissors, and a rotating support structure is connected below the pull sheath and is controlled by a front grip arranged on a front handle. The mechanical brake structure has the following beneficial effects that: the rear handle rotates to be combined with a stay rope, so as to guarantee the reliability of the braking action of the switching trigger on the rear handle; and the risk that one hand of a user touches a moving blade while the other hand operates is avoided, therefore, the safety of the operation of the user is guaranteed.

Description

technical field [0001] The present invention relates to pruning shears with mechanical brakes. Background technique [0002] Pruning shears are a tool commonly used in the garden and landscaping industry to trim tree branches. The mechanical brake pruning shears have a shorter braking time than electronic braking and are more stable and reliable, so the user's operation is safer. At the same time, the mechanical brake will cause less damage to the motor, and the life of the whole machine will be longer, which is very popular among customers. However, there are still some defects in the mechanical brake structure currently on the market: the brake is invalid; the switch trigger is laborious to operate; the internal structure is not compact enough, resulting in a large and bulky appearance; the front and rear handles are fixed, and the grip position and angle cannot be humanized. , Uncomfortable operation for a long time, etc. Contents of the invention [0003] The technic...
