Description
Technical Field
The invention relates to the field of garden tools, in particular to a pair of self-garden shears.
Background
In the landscaping maintenance process, pruning branches by using garden shears is often needed; and the plant is of a great variety in gardens, and the branch of various kinds of plants often differs great, then when adopting fixed gardens to cut and prune, meet comparatively durable branch, and its pruning process often is comparatively labouring.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a hydraulic power-assisted garden shears, which can automatically extend a force arm under the condition of a large shearing resistance, so as to reduce the shearing difficulty and save labor during the shearing process.
The technical scheme adopted by the invention for solving the technical problems is as follows: the hydraulic power-assisted garden shears comprise two mutually hinged shear halves; each scissor half part comprises a cutter head and a knife handle; the knife handle comprises a main rod body and a holding part; the upper end of the main rod body is fixed with the tool bit; a shaft channel is formed in the main rod body along the axis, the upper end of the shaft channel is closed, and the lower end of the shaft channel penetrates through the lower end face of the main rod body; the holding part comprises a porous cylinder body with through holes distributed on the peripheral wall, an oil conveying rod inserted into the shaft channel extends upwards from the porous cylinder body along the axis of the porous cylinder body, and the end part of the oil conveying rod is connected with a sliding plug matched with the shaft channel; the oil conveying rod and the sliding plug are provided with oil conveying shaft holes for communicating the shaft channel and the porous cylinder body; the outer part of the porous cylinder body is also surrounded with a cylindrical cavity capable of deforming in the radial direction, and hydraulic oil which is communicated with the cylindrical cavity, the porous cylinder body, the oil conveying shaft hole and the shaft channel is sealed in the cylindrical cavity, the porous cylinder body, the oil conveying shaft hole and the shaft channel; the upper end of the porous cylinder body is fixedly connected with a sleeve, and the sleeve is sleeved on the peripheral surface of the main rod body.
Preferably, the cylindrical cavity is constructed of rubber.
Preferably, a tension spring is connected between the sliding plug and the bottom of the shaft channel, so that the oil delivery rod can automatically retract after being pulled out, and the surface tension of the cylindrical cavity is maintained by the tension spring, and the surface of the cylindrical cavity is prevented from fluctuating.
The invention has the beneficial effects that: this hydraulic pressure helping hand formula gardens are cut when cutting the branch, if the shearing resistance is great, then the user is great to the pressure of handle of a knife portion of gripping, at this moment, will make the hydraulic oil in the portion of gripping inject into more in the shaft path to outwards pass oil transmission pole makes the whole length of handle of a knife obtain extending, thereby increases user's the application of force arm of force, in order to reduce the operation degree of difficulty, makes the pruning process keep at the level of less effort.

FIG. 3 is a schematic view of the embodiment of FIG. 1 showing the structure of the tool shank in a second state.
Detailed Description
In the embodiment shown in fig. 1-3, the hydraulically assisted garden shears comprise two mutually articulated shear halves 1a, 1 b; each scissor half part comprises a cutter head and a knife handle; the knife handle comprises a main rod body 11 and a holding part 12; the upper end of the main rod body 11 is fixed with the cutter head; a shaft channel 110 is formed in the main rod body 11 along the axis, the upper end of the shaft channel 110 is closed, and the lower end of the shaft channel penetrates through the lower end face of the main rod body 11; the holding part 12 comprises a porous cylinder 121 with through holes distributed on the peripheral wall, an oil delivery rod 122 inserted into the shaft channel 110 extends upwards from the porous cylinder 121 along the axis of the porous cylinder, and the end part of the oil delivery rod is connected with a sliding plug 123 matched with the shaft channel 110; an oil delivery shaft hole (not marked) for communicating the shaft channel 110 and the porous cylinder 121 is formed in the oil delivery rod 122 and the sliding plug 123; a cylindrical cavity 124 capable of deforming in the radial direction is further surrounded outside the porous cylinder 121, and hydraulic oil which is communicated with each other is sealed in the cylindrical cavity 124, the porous cylinder 121, the oil delivery shaft hole and the shaft channel 110; the upper end of the porous cylinder 121 is further fixedly connected with a sleeve 125, and the sleeve 125 is sleeved on the outer circumferential surface of the main rod body 11.
In the garden shears, the cylindrical cavity 124 is made of rubber, and the rubber has high hardness to meet the requirement of good hand feeling, but needs to be elastically deformed under the action of high pressure. A tension spring is connected between the sliding plug 123 and the bottom of the shaft passage 110, so that the oil delivery rod 122 can automatically retract after being pulled out.
Under the condition that the holding part 12 of the hydraulic power-assisted garden shears is not pressurized at all, the holding part 12 is filled with hydraulic oil, the hydraulic oil in the axial channel 110 is in the minimum state, so that the oil conveying rod 122 is completely inserted into the axial channel 110, and the handle of the garden shears is in the first state shown in fig. 2, namely the shortest state; and in the process of cutting branches, if the cutting resistance is large, the pressure of a user on the handle holding part 12 is large, at the moment, the degree of transverse compression of the cylindrical cavity 124 of the holding part 12 is large, so that hydraulic oil in the holding part 12 is injected into the shaft channel 110 more, the oil conveying rod 122 is pushed outwards, the whole length of the handle is extended, namely, the second state shown in fig. 3 is realized, the force application arm of the user is increased at the moment, the operation difficulty is reduced, and the trimming process is kept at a labor-saving level.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
