[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1-5The utility model provides the following technical solutions: a portable hand-held laser rust remover, comprising a laser rust remover body 1, a connecting line 7 connected to the side wall of the laser rust remover body 1, a handle 6 connected to the end of the connecting line 7 away from the laser rust remover body 1, a probe 3 is provided at the end of the handle 6 away from the connecting line 7, an adjustment mechanism 4 is provided between the probe 3 and the handle 6, a suspension component 5 is provided between the laser rust remover body 1 and the handle 6, and a protective component 2 is provided on the periphery of the adjustment mechanism 4.

[0024] Specifically, the suspension assembly 5 includes a support rod 51, a fastening member 52, a connecting seat 53, a limiting rod 54 and a placement ring 55. The support rod 51 is connected to the side wall of the laser rust removal machine body 1. One end of the support rod 51 is connected to the placement ring 55. Both sides of one end of the placement ring 55 are connected to the connecting seat 53. A limiting rod 54 is connected between the two connecting seats 53. The side wall of the limiting rod 54 is provided with a fastening member 52.

[0025] By adopting the above technical solution, after the device is used, under the action of the rotating shaft, one end of the limit rod 54 is rotated away from one of the connecting seats 53, and then the handle 6 is placed inside the placement ring 55, and then under the action of the rotating shaft, one end of the limit rod 54 is rotated and overlapped into one of the connecting seats 53. At the same time, the fastening member 52 is then abutted against the handle 6. The handle 6 can be hung and placed using the support rod 51 and the placement ring 55, and then the connecting line 7 can be hung and placed to avoid wear of the connecting line 7 when dragging on the ground.

[0026] Specifically, the pressing member 52 includes a pressing sleeve 521, a connecting spring 522, a moving rod 523 and a pressing plate 524. The side wall of the limiting rod 54 is connected to the pressing sleeve 521, the moving rod 523 is inserted into the inner part of the pressing sleeve 521, the connecting spring 522 is connected between the pressing sleeve 521 and the moving rod 523, and the end of the moving rod 523 away from the pressing sleeve 521 is connected to the pressing plate 524.

[0027] By adopting the above technical solution, after one end of the limiting rod 54 is rotated and overlapped into one of the connecting seats 53, the clamping plate 524 moves due to the squeezing action of the handle 6. The movement of the clamping plate 524 drives the moving rod 523 to move inside the clamping sleeve 521. The moving rod 523 moves to squeeze the connecting spring 522. The clamping plate 524 can be used to clamp and fix the handle 6 to ensure the stability of the handle 6.

[0028] Specifically, both sides of the end of the moving rod 523 close to the abutting sleeve 521 are connected to the limiting sliders, and a limiting sliding groove is provided on the inner side wall of the abutting sleeve 521 at the position corresponding to the limiting slider.

[0029] By adopting the above technical solution, the movement of the moving rod 523 drives the limit slider to move inside the limit slide groove. When the limit slider moves to fit the side wall of the limit slide groove, the limit slider is blocked and stops moving, thereby preventing the moving rod 523 from continuing to move, preventing the moving rod 523 from detaching from the tight sleeve 521.

[0030] When the present embodiment is used and the laser rust removal operation needs to be performed, the laser rust removal machine body 1 is first moved to the operation state, and then the handle 6 is held by hand to drive the probe 3 to perform the rust removal operation. During the rust removal process, the angle of the probe 3 can be adjusted by the adjustment mechanism 4, thereby facilitating the rust removal operation at different positions. After the rust removal operation is completed, the clamping plate 524 is moved in the direction of the clamping sleeve 521, and then, under the action of the rotating shaft, one end of the limiting rod 54 is rotated away from one of the connecting seats 53, and then the handle 6 is placed inside the placement ring 55, and then, under the action of the rotating shaft, one end of the limiting rod 54 is rotated and overlapped inside one of the connecting seats 53, and then the clamping plate 524 is loosened, and the connecting spring 522 loses the external force and returns to its original state to drive the moving rod 523 to move, and the moving rod 523 drives the clamping plate 524 to move and fit the handle 6, and the handle 6 can be suspended and placed by using the support rod 51 and the placement ring 55, and then the connecting line 7 can be suspended and placed to avoid wear of the connecting line 7 caused by mopping on the ground;

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the protective assembly 2 includes a first protective half cover 21 and a second protective half cover 22. The first protective half cover 21 is provided on one side of the outer periphery of the adjustment mechanism 4, and the second protective half cover 22 is provided on the other side of the outer periphery of the adjustment mechanism 4. Protective pads are connected to the inner side walls of the first protective half cover 21 and the second protective half cover 22.

[0033] Specifically, the protective assembly 2 further includes a tightening screw 23, a plug-in block 24 and a plug-in frame 25. The plug-in frame 25 is connected to both sides of one end of the adjustment mechanism 4. The plug-in block 24 is connected to the side walls of the first protective half cover 21 and the second protective half cover 22 at positions corresponding to the plug-in frame 25. A tightening screw 23 is connected to one side of the plug-in frame 25.

[0034] By adopting the above technical solution, the plug-in blocks 24 on the first protective half-cover 21 and the second protective half-cover 22 are respectively plugged into the two plug-in frames 25 on the adjustment mechanism 4, and then the tightening screw 23 is rotated to rotate and move it to fit the side wall of the plug-in block 24. The plug-in block 24 is tightened and fixed by the tightening screw 23, thereby realizing the connection operation of the first protective half-cover 21 and the second protective half-cover 22 with the adjustment mechanism 4, and facilitating the disassembly and assembly operation of the first protective half-cover 21 and the second protective half-cover 22.

[0035] When this embodiment is used, the plug-in blocks 24 on the first protective half-cover 21 and the second protective half-cover 22 are respectively plugged into the two plug-in frames 25 on the adjusting mechanism 4, and then the tightening screw 23 is rotated to rotate and move it to fit the side wall of the plug-in block 24. The plug-in block 24 is tightened and fixed by the tightening screw 23, so that the first protective half-cover 21 and the second protective half-cover 22 can be connected to the adjusting mechanism 4, which facilitates the disassembly and assembly of the first protective half-cover 21 and the second protective half-cover 22. When the handle 6 is subsequently held to drive the probe 3 to perform rust removal operation, under the action of the first protective half-cover 21 and the second protective half-cover 22, rust can be prevented from splashing onto the operator's hand holding the handle 6, thereby preventing the operator's hand from being contaminated or even injured.

[0036] The structure and principle of the adjustment mechanism 4 composed of an equipment frame, a connecting column, a transmission shaft, a gear, a transmission bar, a rack, a spring a, a pressing bar, a transmission groove, a connecting bar, a support sheet, a spring b, and a touch button in the utility model have been disclosed in a portable hand-held laser rust remover disclosed in Chinese patent application No. 202322725367.7. Its working principle is: an equipment frame is provided on the probe 3, a transmission shaft in the equipment frame, a transmission bar is fixedly connected to the transmission shaft, the probe 3 is fixedly mounted on the transmission bar, a gear is sleeved on the transmission shaft, a spring a is fixedly connected in the equipment frame, a rack is provided on the spring a which meshes with the gear for transmission, a connecting column is provided on the rack, a pressing bar for pressing the rack is fixedly connected to the end of the connecting column, a transmission groove is provided on the rack, a connecting bar slidably connected to the transmission groove is fixedly connected to the bottom end of the connecting column, and the end of the spring a is connected to the connecting column. The connecting strip is fixed, and a touch button for controlling the probe switch is installed on the inner wall of the equipment frame. Two springs b are fixed to the inner wall of the equipment frame, and the ends of the two springs b are fixed to a support piece. The connecting strip is located obliquely above the support piece, and the adjacent corners of the connecting strip and the support piece are arc-shaped. When in use, press the pressing strip, and the connecting strip at the bottom of the connecting column contacts the support piece to move it toward the touch button. Then the support piece contacts the touch button, and then the probe 3 can be started, so that the probe 3 emits a laser to remove rust from the workpiece. When the angle needs to be adjusted to remove rust from the workpiece, continue to press the pressing strip, and the connecting strip contacts the bottom wall of the transmission groove to drive the rack to move downward, and then the angle can be adjusted, so that the angle can be adjusted and the laser can be emitted when pressing a single pressing strip. The operation is convenient, which is conducive to improving the operating comfort of the equipment.

[0037] The working principle and usage process of the present invention are as follows: the present invention inserts the plug-in blocks 24 on the first protective half cover 21 and the second protective half cover 22 into the two plug-in frames 25 on the adjusting mechanism 4 respectively, and then rotates the tightening screw 23 to make it rotate and move to fit the side wall of the plug-in block 24, and uses the tightening screw 23 to tighten and fix the plug-in block 24, so as to realize the connection operation of the first protective half cover 21 and the second protective half cover 22 with the adjusting mechanism 4, which is convenient for realizing the disassembly and assembly operation of the first protective half cover 21 and the second protective half cover 22. When laser rust removal operation is required, the laser rust removal machine body 1 is first moved to the use operation, and then the handle 6 is held by hand to drive the probe 3 to perform rust removal operation. During the rust removal process, under the action of the first protective half cover 21 and the second protective half cover 22, rust can be prevented from splashing onto the operator's hand holding the handle 6, thereby preventing the operator from operating the machine. The hands of the workers are contaminated or even injured. At the same time, the angle of the probe 3 can be adjusted by the adjustment mechanism 4, which facilitates the removal of rust at different positions. After the rust removal operation is completed, the clamping plate 524 is moved in the direction of the clamping sleeve 521, and then under the action of the rotating shaft, one end of the limit rod 54 is rotated away from one of the connecting seats 53, and then the handle 6 is placed inside the placement ring 55, and then under the action of the rotating shaft, one end of the limit rod 54 is rotated and overlapped inside one of the connecting seats 53, and then the clamping plate 524 is loosened, and the connecting spring 522 loses the external force and returns to its original state, driving the moving rod 523 to move. The movement of the moving rod 523 drives the clamping plate 524 to move and fit the handle 6. The handle 6 can be suspended and placed using the support rod 51 and the placement ring 55, and then the connecting line 7 can be suspended and placed to avoid wear and tear of the connecting line 7 caused by dragging on the ground.
