The purpose of this utility model provides a kind of Grass shears, makes that to change assembling between its set of blades and cutter head, handgrip body very easy, can be convenient to change set of blades, can effectively avoid existing Grass shears to assemble the economic loss that toilet not produces because of changeing.

In order to achieve the above object, the utility model provides a kind of Grass shears, comprise the cutter head of assembling set of blades and hold the handgrip body of control usefulness, set of blades comprises knife section and fixed blade, one connecting rod interconnects set of blades with the control bar of holding of handgrip body: it is characterized in that: the end face that cutter head one end engages with the handgrip body is established the groove that plugs together that stays an interval, the cutter head end face is provided with through hole, and this cutter head is sealed set of blades in the bottom, and proper being with handgrip body bottom flushes; And the handgrip body is established class's end of protrusion in the central authorities of the end face that engages with cutter head, this class's end has central axis hole for placing connecting rod, the rod end head is controlled in holding of the knife section of connecting rod connection set of blades and handgrip body, this class's end aligns insert group in cutter head, and in plugging together groove, this is sticked in the scrobicular ring of class's end with a spacer, the fixed blade end of set of blades is locked in the cutter head bottom, will plug together the trench bottom sealing.

Described Grass shears is characterized in that: this spacer can be U-shaped.

Grass shears of the present utility model, the characteristic that it is maximum, promptly be that 20 of cutter head 10 and handgrip bodies are easy insert group, cooperate the insert group engaging of U-shaped spacer 14, make the purpose that reaches easy positioning combination, and the fixed blade 13 of set of blades is enclosed sealed by the bottom, makes the bottom of cutter head 10 be the smooth assembling of sealing, can prevent to take place after spacer 14 is by the bottom insert group puzzlement of loose or dislocation really, reach safety lock dress, firmly in conjunction with effect; When using the back that knife cut passivation situation takes place, just after can be easily the locking bolt 15 of fixed blade 13 being unloaded, can make U-shaped spacer 14 withdraw from clamped position, whole group cutter head 10 just can be taken apart in simple and easy separation, make things convenient for the dismounting of connecting rod 23 and knife section 12, can unload set of blades is complete, sharpen again or renew assembling, need not whole clipper abandoned and renew, can receive the economic effect of practical symbol again.So easy separation plug-in card design with whole group cutter head 10, it really can improve the convenience of assembling and make the actual assembled technology significantly reduce, and cutter head 10 is circular arc usually, when when assembling if the formula that is forced into the by force insert group operation to commonly use is easy to destroy whole cutter head 10 appearance surfaces, more and need special instrument auxiliary, extremely inconvenient, and Grass shears simple and convenient assembly of the present utility model, simple and easy assembling, the purpose that meets the circulation maintenance or change the outfit and use of changeing after more convenient day.

In sum, Grass shears of the present utility model, it cooperates with the default class's end that protrudes that the U-shaped spacer is simple and easy inserts fixed closing, and the assembling location technology between cutter head and handgrip body is significantly simplified, the set of blades of being more convenient for change maintenance.
