Description

A kind of electric shrub and hedge trimmer

Technical field

The utility model relates to a kind of electric shrub and hedge trimmers.

Background technique

The Chinese invention patent of Patent No. 201510072074.0 discloses a kind of electric pruner comprising scissors Ontology, the front end of the scissors ontology are equipped with the cutting blade and ledger-plate that are flexibly connected；The tail end of the scissors ontology is connected with Shell；The driving device for pushing the cutting blade operation is equipped in the shell；The bottom of the shell is equipped with trigger；The drive Dynamic device includes motor, epicyclic gearbox, gear set and power module；Described motor one end is electrically connected with the power module, The other end is mutually driven with the epicyclic gearbox；The epicyclic gearbox is mutually driven with the gear set.Using of the present invention Electric pruner, the characteristics of there is transmission energy be big, noise is small, and blade is readily replaceable, long service life；But this kind of electricity The ledger-plate and cutting blade of dynamic shrub and hedge trimmer are often can't clip during trimming to pollard, and branch is easy between the two It slips and falls off, it is inconvenient for operation, it is time-consuming and laborious.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of electric shrub and hedge trimmers that can preferably clamp branch.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of electric shrub and hedge trimmer, including setting Ledger-plate component and cutting blade in body front end, the ledger-plate component include cutter hub and are adapted with the cutting blade Anvil block, the cutter groove for accommodating the cutting blade is offered on the anvil block.

The further preferred scheme of the utility model are as follows: arc-shaped, the described anvil of the shape of the upper surface of the anvil block The front end of block is provided with anti-slip part compatible with the blade of the cutting blade.

The further preferred scheme of the utility model are as follows: the height of the front end of the anvil block is higher than in the anvil block Between height at portion.

The further preferred scheme of the utility model are as follows: when pruning, be clipped in the cutting blade and described to poll Between anvil block, to the first point of contact between poll and the cutting blade and to second between poll and the anvil block Point of contact is connected to form reference line, at the first point of contact and the first tangent line and said reference straight line that the cutting blade is tangent the The first angle of friction that one vertical line is formed is α, to which there are the first critical friction angle, the degree of α between poll and the cutting blade Degree of the number less than the first critical friction angle.

The further preferred scheme of the utility model are as follows: at the second point of contact and the second tangent line that the anvil block is tangent with it is upper The second angle of friction for stating the second vertical line formation of reference line is β, to critical there are second between poll and the anvil block Angle of friction, the degree of the degree of β less than the second critical friction angle.

The further preferred scheme of the utility model are as follows: the anvil block is fixed at the knife by lock screw On body.

The further preferred scheme of the utility model are as follows: the upper surface of the anvil block offers anti-skidding toothrow, enhancing tree Branch horizontal friction force, further strengthens antiskid effect.

Compared with prior art, the utility model has the advantage of cutting blades and anvil block designs with unique shape, increases Add the frictional force between branch and blade, i.e., so that the degree of α is less than the degree at the first critical friction angle, the degree of β is less than The degree at two critical friction angles, will generate locking phenomenon between branch and cutting blade, anvil block, to poll will not from blade it Between skid off, play anti-skidding effect, pollard is more time saving and energy saving.

Specific embodiment

The utility model is described in further detail below in conjunction with figure embodiment.

Embodiment one: as shown in Figure 1-3, a kind of electric shrub and hedge trimmer, the ledger-plate component 2 including 1 front end of body is arranged in With cutting blade 3, ledger-plate component 2 includes cutter hub 21 and anvil block 22 compatible with cutting blade 3, is offered on anvil block 22 for holding Receive the cutter groove 23 of cutting blade 3, the shape of the upper surface of anvil block 22 is arc-shaped, and the front end of anvil block 22 is provided with the knife with cutting blade 3 The compatible anti-slip part 24 of sword, the height of the front end of anvil block 22 are higher than the height at the middle part of anvil block 22, when pruning, wait cut tree Branch 5 is clipped between cutting blade 3 and anvil block 22, to the first point of contact between poll 5 and moving knife 3 and to poll 5 and anvil block The second point of contact between 22 is connected to form reference line m, at the first point of contact and the first tangent line a1 and above-mentioned base that cutting blade 3 is tangent The first angle of friction that the first vertical line a2 of line of collimation m is formed is α, to which there are the first critical frictions between poll 5 and cutting blade 3 Angle, the degree of α less than the first critical friction angle degree, at the second point of contact and the second tangent line b1 and above-mentioned base that anvil block 22 is tangent The second angle of friction that the second vertical line b2 of line of collimation m is formed is β, to which there are the second critical frictions between poll 5 and anvil block 22 Angle, less than the degree at the second critical friction angle, anvil block 22 is fixed on cutter hub 21 by lock screw 25 for the degree of β.

Embodiment two: as illustrated in figures 4-5, other structures are the same as example 1, the difference is that: anvil block 22 Upper surface offers anti-skidding toothrow 26.

Working principle: by adjusting the shape and angle of blade, Lai Zengjia frictional force is anti-skidding to achieve the purpose that, that is, wants Make the degree of α less than the degree at the first critical friction angle, the degree of the degree of β less than the second critical friction angle, branch and moving knife Locking phenomenon will be generated between piece, anvil block, just will not therefrom be skidded off to poll, realized anti-skidding.

A kind of electric shrub and hedge trimmer provided by the utility model is described in detail above, it is used herein specifically A example is expounded the principles of the present invention and embodiment, and the above embodiments are only used to help understand originally Utility model and core concept.It should be pointed out that for those skilled in the art, it is practical new not departing from this Under the premise of type principle, several improvements and modifications can be made to this utility model, these improvement and modification also fall into this reality With in novel scope of protection of the claims.
