Description

High security garden shearer

Technical field

The utility model relates to garden instrument fields, more specifically, it relates to a kind of high security garden shearer.

Background technique

Currently, the tree strain of Chinese garden planting is more, therefore many nutrients can be consumed when branch is too big, extra bough Item is cut, and consumption will be reduced, and is conducive to tree and is grown tall, and also to keep ornamental trees more beautiful and clean.Therefore it often needs Branch is trimmed, and when fruit tree catches pest and disease damage, cut off the big branch fallen ill, can be reduced the destruction of insect pest.

Present people's pollard is especially larger thicker branch, generally all with common gardens shear, this garden Woods shear is relatively suitable for shearing thinner branch, and needs to expend biggish manpower for thicker branch and go to cut, and cut Being easy to skid after the coarse branch contact of knife makes branch be detached from clipped position；Therefore shear effect is bad.

Utility model content

For the deficiency that the prior art arrives, the utility model aim is to provide a kind of high security garden shearer, has more Strong shear effect.

To achieve the above object, the utility model provides the following technical solutions:

A kind of high security garden shearer, including two blades that are hinged, two blades are connected separately with one He of handle Handle two；It is characterized by also including there is crowbar, one end of the crowbar is provided with pry head；It is opened up on the handle one There is the through slot through its side wall, the stress item of the through slot is provided through on the side wall of the handle two；In the stress The tooth socket abutted with the pry head is offered on the side wall of item, the one end of the crowbar with pry head is supported with the handle one side wall It connects.

So set, pry head is connected in tooth socket, by pulling crowbar, pry head is set to pull stress item, and because of crowbar end Portion is connected to handle one side wall, thus close handle one and handle two further with cutting blade tightly, until object to be cut is cut, it is real The shearing of object is now cut to hardly possible.

Further setting: the stress item is arc-shaped setting, and the center of circle is overlapped with the hinge joint of two blades.

So set, the setting of stress item is arc-shaped, make to remain unchanged when it passes through through slot with through slot both sides spacing, Guarantee that high security garden shearer is smooth in movement, does not occur stuck.

Further setting: the contact surface that the crowbar is abutted with two side wall of handle is arc-shaped setting.

So set, arc-shaped contact surface makes at crowbar end and one relative motion of handle, reducing friction resistance, together When prevent it is stuck.

Further setting: being provided with the double wedge for clamping object to be cut at the blade of two blades, described convex It puts the first edge on a knife or a pair of scissors tooth two sides.

So set, by adding double wedge, in blade closing course, double wedge will object clamping be cut, do not influencing to shear It prevents object to be cut from skidding while function with respect to blade, keeps shearing more stable.

Further setting: it is greater than from the double wedge to the knife edge angular the blade end from the double wedge to described Knife edge angular between insert tip.

So set, making blade have stronger structure strong by increasing double wedge to the knife edge angular between blade end Degree.

Further setting: be serrated setting from the double wedge to the blade the blade end.

Be arranged such: by the way that blade setting is serrated, tip is easier to enter to save shearing more wait cut in object Power, while preventing object to be cut from skidding with respect to blade.

Further setting: extension rod is threaded on the handle one and the handle two.

So set, convenient for carrying out shearing work in higher position, while increasing the arm of force by adding extension rod, reaching To labour-saving effect.

Further setting: the rod cavity that grafting is slid for the handle one and the handle two is provided on the extension rod.

So set, extension rod is socketed on handle one and handle two by setting rod cavity, to realize to extension rod Storage, reduce occupied space.

Further setting: the spacing block set abutted against is provided on the handle one and the handle two.

So set, limiting the rotational angle of blade by abutting two convex blocks, make blade will not in closure rear knife edge It is staggered because corner is excessive.

In summary: pry head being connected in tooth socket, by pulling crowbar, so that pry head is pulled stress item, and because of crowbar end Portion is connected to handle one side wall, thus close handle one and handle two further with cutting blade tightly, until object to be cut is cut, it is real The shearing of object is now cut to hardly possible；By adding double wedge, in blade closing course, double wedge will object clamping be cut, do not influencing to shear It prevents object to be cut from skidding while function with respect to blade, keeps shearing more stable；By adding extension rod, convenient in higher position Shearing work is carried out, while increasing the arm of force, reaches labour-saving effect.

Specific embodiment

High security garden shearer is described further referring to figs. 1 to Fig. 4.

A kind of high security garden shearer, as shown in Figure 1, including the blade 1 that two panels is hinged, two blades 1 are fixed respectively It is connected with handle 1 and handle 23；The spacing block set 12 abutted against is provided on handle 1 and handle 23.

As shown in Figure 1, the double wedge 9 of triangle is provided on the blade of 1 blade 1 of blade in close hinged place, double wedge 9 Two sides are put the first edge on a knife or a pair of scissors processing.In conjunction with Fig. 2, be serrated setting from double wedge 9 to the blade 1 end of blade, and from double wedge 9 to blade Knife edge angular between 1 end is greater than from double wedge 9 to the knife edge angular 1 tip of blade.

As shown in Figure 1, high security garden shearer is also equipped with crowbar 4, it is provided on handle 1 through the logical of its side wall Slot 6, is fixedly installed the stress item 7 for slipping through through slot 6, being arc-shaped on the side wall of handle 23, and circle is located at two knives The hinged place of piece 1；The tooth socket 8 of triangle is provided on the exterior arc surface of stress item 7.In conjunction with Fig. 3, one end of crowbar 4 is arranged There is the pry head 5 abutted with tooth socket 8, the end of crowbar 4 is arc-shaped setting and the contact surface abutted with 23 side wall of handle is in circular arc Shape setting.

As shown in figure 4, being respectively connected with extension rod 10 on handle 1 and handle 23, specifically, extension rod 10 is provided with Rod cavity 11 is provided with internal screw thread on the inner wall of rod cavity 11, in handle 1 and handle 23 for 23 grafting of handle 1 and handle End be provided with external screw thread.Anti-skid chequer is provided on the peripheral wall of extension rod 10.

The course of work: when needing to cut thicker branch, branch is caught between the double wedge 9 of two blades 1, pry head 5 is supported It connects in tooth socket 8, by pulling crowbar 4, pry head 5 is made to pull stress item 7, and because 4 end abutment of crowbar is in one 2 side wall of handle, Tight to make handle 1 and 23 band cutting blade 1 of handle further close, until object to be cut is cut, difficult poll is cut in realization Operation is cut, labour-saving effect is reached.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
