[0030] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] The clamping assembly 5 includes a screw rod 51, one end of which is rotatably connected to one side of the inner wall of the rectangular frame 1, and the other end of the screw rod 51 passes through the inner wall of the rectangular frame 1 and is fixedly connected to a ratchet 52.

A rocker 55 is fixedly connected to the side wall of the ratchet 52, and a limiting mechanism 56 is provided on the side wall of the rectangular frame 1 at a position close to the periphery of the ratchet 52.

[0035] It should be noted that: Figure 5 As shown, when the screw rod 51 rotates clockwise, the splint 53 will move along the screw rod 51 toward the vertical plate 2. When the screw rod 51 rotates counterclockwise, the splint 53 will move away from the vertical plate 2, thereby cooperating with the vertical plate 2 to clamp the finishing material. During the movement of the splint 53, the splint 53 slides on the limit rod 54. The limit rod 54 prevents the splint 53 from rotating when the screw rod 51 drives the splint 53 to rotate.

[0036] Among them, four through grooves 49 are penetrated through the inner wall of the first tube body 44, a stopper 410 is arranged in the first tube body 44, four connecting blocks 411 are fixedly connected to the stopper 410, the connecting blocks 411 penetrate through the through grooves 49 and are fixedly connected to the inner wall of the through hole 43, a first spring 412 is installed inside the first tube body 44, and two ends of the first spring 412 are respectively fixedly connected to the side wall of the stopper 410 and one side of the inner wall of the first tube body 44.

[0038] Among them, the clamping mechanism 48 includes a socket 481 opened on the L-shaped fixing frame 46, the inner wall of the socket 481 is provided with a plurality of second sliding grooves 482, a clamping block 483 is slidably installed in the second sliding groove 482, and limiting grooves 484 are symmetrically opened on both sides of the inner wall of the second sliding groove 482, and limiting blocks 485 are arranged on both sides of the clamping block 483, the limiting blocks 485 extend into the limiting grooves 484 and are slidably connected with the limiting grooves 484, a second spring 486 is fixedly connected to the side wall of the limiting block 485, and the other end of the second spring 486 is fixedly connected to one side of the inner wall of the limiting groove 484, a groove 487 is provided on one side of the clamping block 483, a sliding rod 488 is fixedly connected in the groove 487, an extrusion block 489 is slidably connected to the sliding rod 488, a third spring 4810 is fixedly connected to the bottom of the extrusion block 489, and the other end of the third spring 4810 is fixedly connected to the bottom of the inner wall of the groove 487.

[0039] The clamp block 483 is externally sleeved with a ring 4811 , the ring 4811 is externally threadedly connected with a screw ring 4812 , and the bottom of the screw ring 4812 is fixedly connected to the top of the L-shaped fixing frame 46 .

[0040] It should be noted that: Figure 4 As shown, since the clamp block 483 is a trapezoidal design that is narrow at the top and wide at the bottom, and the inner wall of the ring 4811 fits the outer wall of the clamp block 483, when the ring 4811 rotates and moves downward, the side wall of the clamp block 483 is squeezed by the inner wall of the ring 4811, causing the clamp block 483 to slide in the second slide groove 482 and move toward the center of the socket 481. At this time, the second spring 486 is compressed. When the ring 4811 rotates and moves upward, the second spring 486 stretches and pushes the clamp block 483 away from the center of the socket 481, thereby resetting it.

[0041] Among them, the limiting mechanism 56 includes a block 561 fixed on the side wall of the rectangular frame 1, a resistance block 562 is slidably installed in the block 561, and the side wall of the rectangular frame 1 is fixedly connected with an ear plate 563 at a position close to the block 561. A push rod 564 is arranged through the side wall of the ear plate 563, and the push rod 564 is slidably connected to the ear plate 563. One end of the push rod 564 is fixedly connected to one side of the resistance block 562, and the other end of the push rod 564 is fixedly connected to a first shift plate 565. A fourth spring 566 is sleeved on the outside of the push rod 564, and the fourth spring 566 is fixedly connected to one side of the resistance block 562 and the side wall of the ear plate 563 respectively.

[0042] Among them, a slot 567 is opened on the top of the resistance block 562, the top of the block body 561 is fixedly connected to the frame body 568, a pin head 569 is slidably connected inside the frame body 568, the bottom of the pin head 569 passes through the top of the block body 561 and is slidably connected to the block body 561, the top of the pin head 569 is fixedly connected to the fifth spring 5610, the other end of the fifth spring 5610 is fixedly connected to the top of the inner wall of the frame body 568, and the side wall of the pin head 569 is fixedly connected to the second shift plate 5611.

[0043] A pair of notches 101 are provided on the top of the rectangular frame 1 , and a plurality of transport rollers 102 are rotatably connected to the notches 101 .

[0044] Example:

[0045] like Figure 1 As shown in FIG. 7 , in this embodiment, the device is first placed horizontally on the ground, the marker pen 6 is passed through the insertion hole 481 from the bottom of the L-shaped fixing frame 46, and then the ring 4811 is rotated, and the ring 4811 moves downward, so that the clamping block 483 slides in the second slide groove 482 and moves toward the center of the insertion hole 481, thereby clamping the marker pen 6 through the squeezing block 489.

[0046] Then, the roller 47 of the measuring component 4 is made to contact the wall to be measured, and the finishing material is placed on the top of the rectangular frame 1. Then the staff rotates the ratchet 52 clockwise through the rocker 55. The clockwise rotation of the ratchet 52 drives the screw 51 to rotate synchronously. The rotation of the screw 51 causes the splint 53 to move along the screw 51 toward the vertical board 2. The side wall of the splint 53 contacts one side of the finishing material and pushes it to move toward the vertical board 2 until the other side of the finishing material contacts the side wall of the vertical board 2. Then the screw 51 stops rotating. At this time, the splint 53 cooperates with the vertical board 2 to complete the clamping and fixing of the finishing material. The front end of the resistance block 562 of the limiting mechanism 56 is inserted into the tooth groove of the ratchet 52, thereby preventing the ratchet 52 from rotating, thereby preventing the screw 51 from rotating and causing the splint 53 to move, affecting the clamping firmness.

[0047] It should be noted that: when the finishing material moves on the top of the rectangular frame 1, due to the effect of friction, it will drive a number of transport rollers 102 set on the top of the rectangular frame 1 to rotate, and the transport rollers 102 will cause the top of the rectangular frame 1 and the bottom of the finishing material to roll and rub against each other, thereby avoiding scratching the finishing material when the finishing material moves on the top of the rectangular frame 1.

[0048] After the facing material is clamped and fixed, the staff turns the knob 415 fixedly connected to the top of the screw 414, so that the screw 414 pushes the pressure plate 416 to move downward. When the bottom of the pressure plate 416 hits the top of the marker pen 6, since the extrusion block 489 hits the marker pen 6, the marker pen 6 drives the extrusion block 489 to slide downward along the slide bar 488, and at the same time, the third spring 4810 is compressed, and the pressure plate 416 continues to move downward until the lower end of the marker pen 6 hits the top of the facing material.

[0049] From the above, it can be seen that: the clamping mechanism 48 can be used to install marker pens 6 of different sizes on the measuring component 4, thereby improving the adaptability of the marker pens 6, and the clamping mechanism 48, in cooperation with the extrusion block 489, the slide bar 488 and the third spring 4810, allows the marker 6 to move up and down in the socket 481 in a fixed state, thereby reserving the space required for finishing materials of different thicknesses, and can also adjust the resistance force between the marker 6 and the top of the finishing material to improve drawing clarity.

[0050] Then the staff member holds the handle 421 and pushes the slider 41 to move along the first slide groove 3, thereby driving the measuring assembly 4 to move. The roller 47 connected to one end of the second tube body 45 is rotated to contact the special-shaped wall and roll along the wall contour. In this process, the first tube body 44 slides in the through hole 43 of the mounting block 42 according to the wall contour. When the roller 47 moves from the concave part of the wall contour to the protruding part of the wall contour, the roller 47 pushes the second tube body 45 to move toward the mounting block 42, thereby driving the first tube body 44 to slide in the same direction in the through hole 43. At the same time, the side wall of the stopper 410 and the inner wall of the first tube body 44 The first spring 412 fixedly connected to one side of the wall is compressed. When the roller 47 moves from the protruding part of the wall contour to the recessed part of the wall contour, the first spring 412 stretches, pushing the first tube body 44 to drive the second tube body 45 to move toward the wall, so that the roller 47 always contacts the wall. While the roller 47 moves along the wall contour, the marker pen 6, driven by the first tube body 44, moves synchronously on the top of the finishing material, thereby drawing the contour of the special-shaped wall on the top of the finishing material, and the staff then cuts the finishing material according to the contour line of the special-shaped wall drawn on the finishing material.

[0051] From the above, it can be seen that: through the cooperation of the measuring component 4 and the marking pen 6, the precise size can be drawn on the top of the finishing material according to the contour of the special-shaped wall, which is convenient for scheme design and ground paving construction, and avoids the problem of loose connection between the finishing material and the special-shaped wall due to poor measurement accuracy, which affects the construction quality. In addition, the measurement operation of this device is simple and can effectively improve the measurement efficiency.

[0052] When the measurement is completed, the finishing material needs to be removed. First, the staff pulls the first dial plate 565 to make the push rod 564 drag the resistance block 562 in the block body 561 toward the ear plate 563 and compress the fourth spring 566. When the slot 567 opened at the top of the resistance block 562 moves to below the pin head 569, the pin head 569 is inserted into the slot 567 under the push of the fifth spring 5610, so that the front end of the resistance block 562 is disengaged from the tooth groove of the ratchet 52. At this time, the staff can rotate the ratchet 52 counterclockwise through the handle 421 to make the screw rod 51 drive the splint 53 to move toward the ratchet 52, thereby loosening the clamping of the finishing material, making it easier for the staff to remove the finishing material.

[0053] It should be noted that: when the facing material is in a clamping state, the ratchet 52 needs to be limited, and the staff pushes the second shift plate 5611 upward so that the second shift plate 5611 drives the pin head 569 to slide upward in the frame 568 and compresses the fifth spring 5610, so that the pin head 569 is disengaged from the slot 567 at the top of the resistance block 562. When the pin head 569 is disengaged from the slot 567, the fourth spring 566 compressed on one side of the resistance block 562 stretches and pushes the resistance block 562 to move toward the ratchet 52, so that the front end of the resistance block 562 is inserted into the tooth groove of the ratchet 52, thereby limiting the ratchet 52, and then maintaining the clamping force of the splint 53 and the vertical plate 2 on the facing material.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention.
