Description

The structure that is used for the locking cutter of power shovel
Technical field
The utility model relates to a kind of structure of cutter, relates to a kind of structure that is used for the locking cutter of power shovel specifically, and existing power shovel adopts this structure can realize that the power shovel cutter packs into fast and pin and take out fast.
Background technology
Power shovel is a kind of electric tool that reciprocating cutter is housed, and generally is to be used for wood carving, to root out paint or to root out the unnecessary solidified glue in surface etc. when finishing.Power shovel in use according to the purpose difference of work, often often will be changed cutter.For guarantee power shovel in use cutter can not drop out, to reach the purpose of safe handling, existing power shovel generally is to adopt screw, spring pressuring plate or screw chuck structure to solve this problem both at home and abroad, and above-mentioned existing solution is not complex process or changes inconvenience, is exactly that effect is bad.
Summary of the invention
The technical problems to be solved in the utility model is exactly that existing power shovel is in the problems referred to above that exist aspect the replacing cutter, for people provide a kind of structure that is used for power shovel locking cutter that realizes changing safely, fast the power shovel cutter.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model is made up of front rest, back tool rest, pin, spring, push pedal; Front rest and back tool rest are positioned on the same axis, and it axially is equipped with the passage that passes for cutter; Back tool rest vertically is provided with a cavity, the pin of outer casing spring end insert this cavity, the other end props up push pedal; The lower section of push pedal is triangular in shape, and by moving forward and backward of push pedal, under the cooperation of spring, pin can move up and down along the cavity of back tool rest.
For make the push pedal that is installed on the power shovel shell can opposite shell slide again can be on shell relative positioning, outside projection respectively on two sides identical of push pedal top with its direction of motion, the inboard of aforementioned two projections respectively has a dead slot.Corresponding with the projection in the push pedal, the relevant position that the power shovel shell is used to install the position of push pedal has the locating slot that matches with shape for lugs in the push pedal.
For the quick replacing that realizes cutter and fixing, have a hole similar to the cross sectional shape of pin to the corresponding site of the matching used cutter of the utility model.
The utility model is simple in structure, and is easy to implement, applicable to various power shovels, can easily realize the quick replacing and the locking of cutter.

The specific embodiment
Describe the details and the working condition of power shovel locking cutter structure in detail below in conjunction with accompanying drawing.
Referring to Fig. 1 to Fig. 4, the utility model is made up of front rest 6, back tool rest 5, pin 2, spring 3, push pedal 4; Front rest 6 is positioned on the same axis with back tool rest 5, and it axially is equipped with the passage that passes for cutter; Back tool rest 5 vertically is provided with a cavity, the pin 2 of outer casing spring 3 an end insert this cavity, the other end props up push pedal 4; The lower section of push pedal 4 is triangular in shape, and by moving forward and backward of push pedal 4, under the cooperation of spring 3, pin 2 can move up and down along the cavity of back tool rest 5.
Each projection 7 that outside cross section is triangular in shape on two sides identical with its direction of motion of the top of push pedal 4, the inboard of two projections respectively has a dead slot 9 in the push pedal 4.Corresponding with the projection in the aforementioned push pedal 4, the both sides that the power shovel shell is used to install the position of push pedal respectively have two locating slots that match with shape for lugs in the push pedal 4.The effect of the dead slot 9 of two projections, 8 inboards is can make when push pedal 4 is pushed it under the pushing of power shovel shell and produce deformation in the push pedal 4, thereby two projections 8 in the push pedal 4 can be in two locating slots in the power shovel shell 7 be deviate from; When push pedal 4 promotes to put in place, two projections 8 on it can under the effect of the screen resilience that dead slot 9 produces, enter again on the power shovel shell corresponding another to locating slot 7 in.
Referring to Fig. 6, in order to match with pin 2, the corresponding site of matching used cutter has a hole similar to the cross sectional shape of pin 2.
When the utility model is in Fig. 1 and Fig. 3 state, push pedal 4 is positioned at high-order relatively, two projections on it are positioned at and are positioned at two high-order relatively locating slots on the power shovel shell, pin 2 resilience and also be in relatively high-orderly under the effect of spring 3, cutter 1 can pass front rest 6 and back tool rest 5 and inserted and put in place this moment.
Referring to Fig. 5 when push pedal 4 is pushed down and makes that the utility model is in Fig. 2 and Fig. 4 state, push pedal 4 is in relative low level, two projections 8 on it are positioned at two locating slots 7 that are positioned at relative low level on the power shovel shell, pin 2 inserts in the cavity of cutter 1 under the extruding of push pedal 4 simultaneously, thereby pins cutter 1.
When needing to take out cutter 1,, can easily cutter be taken out when making the utility model be in Fig. 1 or Fig. 3 state as long as will draw in the push pedal 4.
