DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0024] First embodiment:

[0025] like Figure 1-4 As shown, the utility model provides a thorn-proof pruning knife for a soapberry tree, comprising: a pruner 100, a cavity is arranged in the pruner 100, a rod sheath 103 is arranged in the cavity, the rod sheath 103 is embedded in the inner cavity of the pruner 100, a scabbard 107 and a fixed blade 108 are fixedly installed at one end of the rod sheath 103 through a positioning bolt, and one end of the rod sheath 103 is detachably connected to a handle 104 through a pre-tightening bolt 106, one end of the handle 104 is connected to a fixing plate 110 through a spring member 109, the fixing plate 110 is fixedly installed at the bottom end of the pruner 100, and a positioning assembly 300 is further arranged on the end side of the pruner 100, the positioning assembly 300 comprises a positioning plate 301 fixed to the upper end of the pruner 100, the positioning plate 301 is detachably installed on the pruner 100 through the positioning bolt, and limiting cavities 302 are further arranged on both sides of the positioning plate 301, and a protective assembly 300 is inserted into the limiting cavity 302 Component 200, the protection component 200 includes a protection frame 201 inserted into the limiting cavity 302, and the handle 104 and the fixed plate 110 are surrounded in the protection frame 201. During actual installation, the staff first fixes the positioning plate 301 to the end side of the trimmer 100 through the positioning bolt, and then engages the moving block 202 provided on the protection frame 201 into the notch provided on the positioning plate 301, and then installs the limiting plates 303 and the adjusting rod 203 at both ends, so that the adjusting rod 203 passes through the moving block 202 provided on the protection frame 201. After installation, when the trimmer is dealing with branches full of soapberry thorns, he only needs to hold the handle 104, and through the compression of the handle 104, the scabbard 107 is driven to retract, and the scabbard 107 is cooperated with the fixed blade 108 to shorten the diagonal thorns. At this time, the protection frame 201 can also prevent the horn thorns around the branches from being scratched.

[0026] By cooperating with the multiple parts in the protective assembly 200, the handle 104 and the fixing plate 110 can be protected by surrounding. By protecting the handle 104 and the fixing plate 110, when the pruning personnel deal with the barbs on the soapberry tree, the soapberry thorns can be prevented from causing injuries to the pruning personnel during the pruning process. At the same time, a protective pad 105 is provided on the end side of the handle 104. The protective pad 105 is a silicone structure, which can reduce the hard feeling of the pruning personnel when holding it.

[0027] Second embodiment:

[0028] like Figure 4 As shown, the protective frame 201 is composed of two blocks, and a moving block 202 is also provided on the protective frame 201. The moving block 202 is welded to the protective frame 201, and the moving blocks 202 at both ends are connected through an adjusting rod 203, and one end of the adjusting rod 203 is fixed on the limiting plate 303. In actual use, due to the different hand sizes of the trimmers, the trimmers rotate the adjusting rod 203, and the rotation of the adjusting rod 203 drives the moving block 202 to move, and the movement of the moving block 202 drives the protective frame 201 to move left and right.

[0029] By using the movable block 202 in cooperation with the adjusting rod 203, the distance between the left and right protective frames 201 can be adjusted. By adjusting the distance between the left and right protective frames 201, in actual use, since the hand sizes of the trimmers are different, by adjusting the left and right distance between the protective frames 201, it can be suitable for different trimmers, making the trimmer 100 have a wider range of application.

[0030] Third embodiment:

[0031] like Figure 4 As shown, the adjustment rod 203 is a positive and negative thread structure, and the protective frame 201 is symmetrically embedded in the limiting cavity 302 provided in the positioning plate 301 through the moving block 202. The adjustment rod 203 is a positive and negative thread structure. In actual use, the adjustment rod 203 is set as a positive and negative thread structure. During actual adjustment, the protective frames 201 at both ends can be adjusted synchronously, which is convenient for the trimmers to adjust without the need for two adjustments at both ends. At the same time, through the synchronous adjustment, the protective frames 201 at both ends can be kept symmetrical, preventing the staff from affecting the work efficiency due to the left-right asymmetry of the protective frame 201 when holding the handle 104.

[0032] Fourth embodiment:

[0033] like Figure 1-2As shown, a notch 102 is further provided on the end side of the trimmer 100, and a pre-tightening bolt 106 is provided on the outer end side of the trimmer 100. When the scabbard 107 needs to be replaced due to long-term use, the staff can loosen the pre-tightening bolt 106 by twisting the pre-tightening bolt 106 to achieve the separation of the handle 104 from the rod sheath 103. At this time, the rod sheath 103 can be pulled out, and then the scabbard 107 provided on the rod sheath 103 can be disassembled and replaced.

[0034] The detachable installation of the pre-tightening bolt 106 and the rod sheath 103 facilitates the subsequent replacement of the scabbard 107. At the same time, the inner cavity of the trimmer 100 can be cleaned by pulling out the rod sheath 103, thereby preventing a large amount of dust from accumulating in the inner cavity after long-term use, thereby affecting the sliding of the rod sheath 103 inside.

[0035] Fifth embodiment:

[0036] like Figure 1-3 As shown, slide bars 111 are also provided at both ends of the rod sheath 103, and slide grooves are provided at both ends of the inner cavity of the trimmer 100. The rod sheath 103 moves left and right in the slide groove provided in the trimmer 100 through the slide bars 111. In actual use, when the trimmer holds the handle 104 by hand, the slide bars 111 provided at both ends of the rod sheath 103 move back and forth on the slide groove provided in the trimmer 100.

[0037] By using the slide bars 111 provided at both ends of the rod sheath 103 in conjunction with the slide groove provided on the trimmer 100, in actual use, the cooperation between the slide bars 111 and the slide groove can reduce the friction when the rod sheath 103 moves, thereby making the movement of the rod sheath 103 smoother and making it easier for the trimmer to hold it.

[0038] Sixth embodiment:

[0039] like Figure 2 , Figure 4 As shown, weight-reducing cavities 204 are provided at both ends of the protective frame 201, and the opening sizes of the weight-reducing cavities 204 at both ends are the same, and grooves 101 are also provided at both ends of the trimmer 100. In actual use, the weight-reducing cavities 204 provided at both ends of the protective frame 201 and the grooves 101 provided at both ends of the trimmer 100 can reduce the overall weight of the trimmer 100, making it easier for the trimmer to hold it.

[0040] Working principle: During the actual installation, the staff first fixes the positioning plate 301 on the end side of the trimmer 100 through the positioning bolts, and then engages the moving block 202 provided on the protective frame 201 into the notch provided on the positioning plate 301, and then installs the limit plates 303 and the adjusting rod 203 at both ends, so that the adjusting rod 203 passes through the moving block 202 provided on the protective frame 201. After the installation, when the trimmer is dealing with the branches full of soapberry thorns, he only needs to hold the handle 104, and through the compression of the handle 104, the scabbard 107 is driven to retract, and through the cooperation of the scabbard 107 and the fixed blade 108, the diagonal thorns are cut short. At this time, the protective frame 201 can also prevent the corner thorns around the branches from being scratched.

[0041] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
