Description

Technical Field

[0001] The utility model relates to the technical field of gardening equipment, in particular to a tool for removing shrubs and thorns. Background Art

[0002] In order to maintain the beauty of the garden, workers often pull out dead shrubs. The traditional methods include: using a shovel to manually pull out the dead shrubs, or using manpower to pull them out. The traditional pulling method not only requires manual operation, but also consumes a lot of physical energy from the workers, especially when pulling out some stubborn shrubs.

[0003] Through searching, it was found that the prior art has the announcement number: CN112335350B. When encountering a shrub, the clamping part one and the clamping part two can be opened to clamp the shrub. In order to further clamp the shrub, the double-headed hydraulic rod can be controlled by the control button to further clamp the shrub. The user uses the pointed end as a fulcrum and holds the rod body upward to pull out the shrub. If the root system of the shrub to be pulled out is deep and the user is not strong enough to pull it out, the supporting hydraulic rod can be placed on the ground. By controlling the control button, the shrub can be pulled out under the joint action of the user and the supporting hydraulic rod. The extension rod can be further pulled out to extend the lever arm to provide greater pulling force.

[0004] Although the above products have good removal effects, the use of hydraulic rods not only makes the product structure complicated but also increases the overall weight of the product, thereby affecting its promotion. Utility Model Content

[0005] The purpose of the utility model is to provide a bush and thorn removal tool to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shrub thorn removal tool, comprising a bracket, a crowbar rotatably mounted on the bracket; a chuck is provided at the end of the crowbar facing the shrub, and a linkage shaft is also provided inside the crowbar; the chuck comprises a first clamping plate and a second clamping plate; the second clamping plate slides on a guide column provided on the first clamping plate through a slider provided; a connecting piece is also provided inside the slider, and the connecting piece is threadedly matched with an externally threaded column provided on the linkage shaft through an internally threaded hole provided; the guide column is movably connected to the crowbar through a connecting portion provided; a sliding groove is also provided on the guide column, and the connecting piece slides in the sliding groove.

DETAILED DESCRIPTION

[0020] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0021] See also Figure 1-6 The utility model provides an embodiment of a shrub thorn removal tool, comprising a bracket 4, on which a pry bar 1 is rotatably mounted; a chuck 3 is provided at one end of the pry bar 1 facing the shrub, and a linkage shaft 7 is also provided inside the pry bar 1; the chuck 3 comprises a first clamping plate 31 and a second clamping plate 32; the second clamping plate 32 slides on a guide column 39 provided on the first clamping plate 31 through a slider 33 provided; a connecting piece 36 is also provided inside the slider 33, and the connecting piece 36 is threadedly matched with an external threaded column 8 provided on the linkage shaft 7 through an internal threaded hole 35 provided; the guide column 39 is movably connected to the pry bar 1 through a connecting portion 30 provided; a slide groove 38 is also provided on the guide column 39, and the connecting piece 36 slides in the slide groove 38.

[0022] To sum up, after the chuck 3 clamps the bush, the other end of the crowbar 1 is pressed. At this time, the crowbar 1 can easily pull out the bush by using the lever principle under the action of the bracket 4. Since the second clamping plate 32 can slide on the first clamping plate 31 under the action of the linkage shaft 7, the first clamping plate 31 and the second clamping plate 32 do not need to use hydraulic equipment in the process of clamping the bush, thereby reducing the overall weight of the equipment and simplifying the structure of the equipment to facilitate the promotion of the equipment; in particular: with the continuous rotation of the linkage shaft 7, the clamping force between the two clamping plates can be continuously strengthened, thereby ensuring that the bush will not fall off during the pulling out process. At the same time, the two clamping plates are open structures, so that the two clamping plates can contact the bush over a large area and can clamp larger bushes, so as to further improve the bush removal efficiency and scope of application of the equipment.

[0023] In addition, in order to facilitate the installation and replacement of the chuck 3, the connecting portion 30 is adapted to be connected with the plug 6 provided at the end of the crowbar 1 through the slot 34 provided; therefore, the assembly or disassembly of the chuck 3 and the crowbar 1 can be completed by plugging and unplugging; and after assembly, a bolt is passed through the connecting portion 30 and pressed against the plug 6 to enhance the structural strength of the chuck 3 and the crowbar 1 after connection. Among them, the cross-sections of the plug 6 and the slot 34 are both polygonal, such as hexagonal; therefore, the problem of the chuck 3 rotating on the crowbar 1 can be prevented by the cooperation between the plug 6 and the slot 34. In addition, after the slider 33 is installed on the guide column 39, the connecting portion 30 is welded to the guide column 39.

[0024] Since the slider 33 is also provided with a mounting groove 37, and the connecting member 36 passes through the mounting groove 37 and the slide groove 38 and slides in the guide column 39, therefore, when the external threaded column 8 on the linkage shaft 7 is connected with the internal threaded hole 35, as the linkage shaft 7 rotates, the slider 33 can be reliably caused to slide along the guide column 39. At the same time, when the two ends of the connecting member 36 pass through the slider 33 and are connected to the nut, the assembly and fixation of the connecting member 36 is facilitated.

[0025] On the basis of the above scheme, since the end of the crowbar 1 away from the chuck 3 is also provided with a driving part 2, and the driving part 2 is connected to the connecting column 9 provided on the linkage shaft 7 through the provided mounting hole 10, through the above method, the user can cause the linkage shaft 7 to rotate through the driving part 2, and at the same time, in order to ensure the reliable output of power between the driving part 2 and the linkage shaft 7, the connecting column 9 is connected to the mounting hole 10; wherein the cross-sections of the connecting column 9 and the mounting hole 10 are both polygonal, for example, hexagonal. In addition, after the driving part 2 is connected to the connecting column 9, a bolt can also be used to penetrate the driving part 2 and tighten it on the connecting column 9 to prevent the driving part 2 from falling off during use.

[0026] Furthermore, since the bracket 4 is connected to the support seat 5 by an axle pin, and the crowbar 1 slides in the support seat 5, the crowbar 1 can slide along the support seat 5 to adjust the torque of the crowbar 1, thereby further reducing the user's physical expenditure.

[0027] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
