Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastering devices, and more specifically, to a plastering device. Background Art
[0002] In the existing technology, there are some limitations in the design of the plastering device, which affect its use efficiency and the user's operating experience.
[0003] Firstly, the structural design of most plastering devices is relatively fixed, which means that the position of the handle cannot be flexibly adjusted. This design defect has an adverse effect because different construction environments and the needs of constructors may require the handle to be in different positions for easy operation and force application. The fixed-structure plastering device cannot adapt to these changes, thus limiting its applicability in different situations.
[0004] Secondly, the handle in the prior art is usually fixedly installed on one side of the plastering board. This design is not convenient for quick disassembly and connection. When the handle is damaged or needs to be replaced, the user often has no choice but to discard the entire plastering device, which not only increases costs but also causes waste of resources. In addition, since each person's hand size and holding habits are different, the requirements for handle length and thickness will also vary. The fixedness of the existing handle design limits the flexibility of users to choose suitable handles according to personal preferences and needs, which undoubtedly reduces the applicability and user satisfaction of the plastering device.
[0005] In addition, although some existing devices attempt to use some mechanisms to achieve rapid disassembly and assembly of the handle, these mechanisms are often simple in structure and cannot ensure a stable connection. During use, this unstable connection may cause the handle to shake, affecting the accuracy and efficiency of the operation. What is more serious is that this shaking may cause the handle to fall off one side of the plastering board, which not only interrupts the construction process, but may also cause safety accidents and harm to construction workers.

[0035] The diameter of the clearance groove 20 is slightly larger than the diameter of the limiting rod 19 .
[0036] In this embodiment, when the handle 2 needs to be replaced, the matching sleeve 18 is first rotated so that the matching sleeve 18 drives the return block 15 to move, and then the return block 15 cooperates with the fixed block 17 to squeeze the spring 16, and at the same time, the matching sleeve 18 drives the limit rod 19 and the first push spring 23 to move. When the limit rod 19 and the clearance groove 20 are in position, the control plate 3 is pushed downward, and the control sleeve drives the clearance groove 20 to move, so that the limit rod 19 passes through the limit groove, and then the control plate 3 and the matching sleeve 18 cooperate to squeeze the first push spring 23, and then The rear control panel 3 drives the connecting rod 4 to slide along the sliding groove 5, and the control panel 3 drives the lower pressing sleeve 11 to move through the connecting rod 4. Due to the chamfered structural design of the inner wall of the lower pressing sleeve 11 and the rounded structural design of one end of the adapter rod 13, the inner wall of the lower pressing sleeve 11 will press the adapter rod 13 into the installation groove 9, and the adapter rod 13 will squeeze the second push spring 10 connected to one side, and then the handle 2 is pulled outward to pull the fixing rod 7 out of the fixing sleeve 8, and then the fixing rod 7 connected to one end of the replaced handle 2 is inserted Into the fixing sleeve 8, due to the inclined structural design of the guide platform 6, during the insertion process, the inner wall of the guide platform 6 squeezes the adapter rod 13, so that the adapter rod 13 enters the installation groove 9 and squeezes the second push spring 10. When the fixing rod 7 is fully inserted into the fixing groove, the control plate 3 is released, and the first push spring 23 pushes the control plate 3 to reset, so that the control plate 3 drives the lower pressing sleeve 11 to reset through the connecting rod 4, and then one end of the adapter rod 13 loses the limit of the inner wall of the lower pressing sleeve 11, and then the second push spring 10 pushes the adapter rod 13 to reset, so that The adapter rod 13 is engaged with one side of the adapter sleeve 12 through the adapter groove 14. When the control sleeve is completely reset, the spring 16 pushes the return block 15 to reset, and then the return block 15 drives the matching sleeve 18 to reset, so that the matching sleeve 18 drives the limit rod 19 and the first push spring 23 to reset, and then the position of the limit rod 19 and the position of the give way groove 20 no longer correspond, so that the limit rod 19 forms a stable support for the control panel 3 to prevent the control panel 3 from driving the pressure sleeve 11 to move, thereby ensuring the stability of the connection structure while realizing the rapid replacement of the handle 2.
[0037] See also Figure 1-2 As an implementation of the adjustment device: the adjustment device includes a slide rail 24, a slide groove 25 and a support frame 26, the slide rail 24 is fixedly connected to one side of the plastering board 1, the slide groove 25 is opened on the inner side of the support frame 26, and the support frame 26 is slidably set on one side of the plastering board 1 through the slide groove 25 and the slide rail 24.
[0038] Screw rods 27 are symmetrically arranged on both sides of the slide rail 24 , and the screw rods 27 are detachably installed in the support frame 26 through threads.
[0039] Knobs 28 are symmetrically provided on both sides of the support frame 26 , and the knobs 28 are fixedly connected to one end of the screw rod 27 .
[0040] More specifically, when the position of the handle 2 needs to be adjusted, the knobs 28 provided on both sides of the support frame 26 are first rotated respectively. The knobs 28 drive the screw rod 27 to rotate, so that the screw rod 27 moves along the thread line, and then the other end of the screw rod 27 no longer presses the slide rail 24, and then the support frame 26 is pushed, so that the support frame 26 slides along the slide rail 24 through the slide groove 25.

At the same time, the control plate 3 drives the lower pressing sleeve 11 to move through the connecting rod 4. Due to the chamfered structural design of the inner wall of the lower pressing sleeve 11 and the rounded structural design of one end of the adapter rod 13, the inner wall of the lower pressing sleeve 11 will press the adapter rod 13 into the installation groove 9. At the same time, the adapter rod 13 will squeeze the second push spring 10 connected to one side. Then the handle 2 is pulled outward, the fixing rod 7 can be pulled out of the fixing sleeve 8, and then the fixed rod 7 connected to one end of the replaced handle 2 can be connected to the fixing sleeve 8. The rod 7 is inserted into the fixing sleeve 8. Due to the inclined structural design of the guide platform 6, during the insertion process, the inner wall of the guide platform 6 squeezes the adapter rod 13, so that the adapter rod 13 enters the installation groove 9 and squeezes the second push spring 10. When the fixing rod 7 is fully inserted into the fixing groove, the control plate 3 is released, and the first push spring 23 pushes the control plate 3 to reset, so that the control plate 3 drives the lower pressing sleeve 11 to reset through the connecting rod 4, and then one end of the adapter rod 13 loses the limit of the inner wall of the lower pressing sleeve 11, and then the second push spring 10 pushes the adapter rod 13 to reset. The adapter rod 13 is engaged with one side of the adapter sleeve 12 through the adapter groove 14. When the control sleeve is completely reset, the spring 16 pushes the return block 15 to reset, and then the return block 15 drives the matching sleeve 18 to reset, so that the matching sleeve 18 drives the limit rod 19 and the first push spring 23 to reset, and then the position of the limit rod 19 and the position of the give way groove 20 no longer correspond, so that the limit rod 19 forms a stable support for the control panel 3 to prevent the control panel 3 from driving the lower pressure sleeve 11 to move, thereby ensuring the stability of the connection structure while realizing the rapid replacement of the handle 2.
[0042] When the position of the handle 2 needs to be adjusted, first rotate the knobs 28 set on both sides of the support frame 26 respectively. The knobs 28 drive the screw rod 27 to rotate, so that the screw rod 27 moves along the thread line, and then the other end of the screw rod 27 no longer presses the slide rail 24, and then push the support frame 26, so that the support frame 26 slides along the slide rail 24 through the slide groove 25. When it moves to the appropriate position, rotate the knob 28 in the opposite direction so that the other end of the screw rod 27 presses the two sides of the slide rail 24 again, so that the support frame 26 is firmly installed on one side of the plastering board 1, thereby achieving the purpose of adjusting the position of the handle 2.
