Description

Technical Field

[0001] This utility model relates to the field of cutting tools, and in particular to a compact push knife. Background Technology

[0002] Tiles now play an important role in home decoration as a building material. Tile pushers are commonly used tile cutting equipment. On the decoration site, tile pushers can be used to cut large tiles into multiple tiles of the target size to meet different decoration requirements.

[0003] The patent with publication number CN207267295U shows a new type of single-rail carriage for a tile cutting machine. In this case, the plastic card holder has a groove on its card slot surface and the outer side of the groove wall is arc-shaped. The opening end face of the groove wall is flat. The connection between the plastic card holder and the connecting shaft mounted on the bearing is not stable. The plastic card holder and the connecting shaft are prone to shaking, which causes the pusher to not slide in a straight line when in use. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a compact pusher that solves the issue of easy wobbling between the card holder and the connecting shaft, which prevents the pusher from sliding linearly during use.

[0005] The technical solution adopted by this utility model is as follows: a compact pusher includes a support plate, a first support shell, a second support shell, a guide plate, a placement plate, a cutting device, and a measuring device. The first support shell and the second support shell are mounted on the support plate, and the guide plate is mounted on the first support shell and the second support shell. The cutting device is slidably connected to the guide plate, and the measuring device is mounted on one side of the support plate. The placement plate is mounted on the support plate. The cutting device includes a first half-shell, a second half-shell, a rotating shell, a pressure plate, and a cutter head. The rotating shell is provided with a handle and is rotatably connected to the first half-shell and the second half-shell. The pressure plate and the cutter head are disposed on the rotating shell. The first half-shell and the second half-shell are each equipped with a mounting seat. The mounting seat is provided with an installation opening. The opening width of the installation opening is smaller than the diameter of the installation opening. A connecting shaft is connected to the installation opening. A first rotating component is disposed on the connecting shaft. When the first half-shell and the second half-shell slide on the guide plate, the first rotating component rolls on the side of the guide plate.

[0006] With the above technical solution, after the connecting shaft is installed in the mounting port on the mounting tool holder, the mounting port limits the connecting shaft, preventing the connecting shaft from shaking in the mounting port and making it difficult for the connecting shaft to detach from the mounting port.

[0007] Furthermore, the first half-shell and the second half-shell are provided with slots, and the card holder is fitted into the slots.

[0008] With the above technical solution, the card holder fits snugly into the socket, ensuring a tight fit and preventing the card holder from easily becoming loose.

[0009] Furthermore, the card holder is provided with a protrusion, and the edge of the insertion port is provided with a card groove, the protrusion and the card groove being fitted together.

[0010] With the above technical solution, the protrusion and the card slot fit together, the connection between the card holder and the card slot is more stable, and the card holder is not easy to detach from the socket.

[0011] Furthermore, the number of protrusions on a single card holder is at least two, and the protrusions on a single card holder are symmetrically arranged on both sides of the card holder.

[0012] The above technical solution makes the connection between the card holder and the socket tighter, preventing the card holder from shaking on the socket.

[0013] Furthermore, the card holder and the socket are arranged in groups, and multiple groups of the card holder and the socket are provided on the first half shell and the second half shell.

[0014] With the above technical solution, each card holder is connected to a connecting shaft, and each connecting shaft is equipped with a first rotating component. Multiple first rotating components on the first half shell and the second half shell roll on the side of the guide plate, so that the entire cutting device can slide better on the guide plate.

[0015] Furthermore, the edge of the socket is provided with a clearance opening, which avoids the connecting shaft.

[0016] The above technical solution facilitates the installation of the connecting shaft.

[0017] Furthermore, both the first half-shell and the second half-shell are provided with limiting blocks, which are located on both sides of the connecting shaft.

[0018] The above technical solution prevents the connecting shaft from wobbling up and down.

[0019] Furthermore, the first half-shell and the second half-shell are connected to a mounting rod, and the mounting rod is provided with a second rotating member. When the first half-shell and the second half-shell slide on the guide plate, the second rotating member rolls on the upper and lower sides of the guide plate.

[0020] By using the above technical solution, the friction between the first and second half-shells and the guide plate is reduced, allowing the entire cutting device to slide better on the guide plate.

[0021] Furthermore, the first half-shell is provided with a first notch and a second notch, and the second half-shell is provided with a third notch and a fourth notch. The opening formed by the first notch and the third notch, and the opening formed by the second notch and the fourth notch, can both allow the guide plate to pass through.

[0022] Through the above technical solution, the opening formed by the first notch and the third notch, and the opening formed by the second notch and the fourth notch, form a channel, and the first half shell and the second half shell can slide on the guide plate without shaking.

[0037] See Figures 1-4A compact push knife includes a support plate 1, a first support shell 2, a second support shell 3, a guide plate 4, a placement plate, a cutting device 6, and a measuring device 7. The first support shell 2 and the second support shell 3 are mounted on the support plate 1, and the guide plate 4 is mounted on the first support shell 2 and the second support shell 3. The cutting device 6 is slidably connected to the guide plate 4. The measuring device 7 is mounted on one side of the support plate 1, and the placement plate is mounted on the support plate 1. The cutting device 6 includes a first half-shell 601, a second half-shell 602, a rotating shell 603, a pressure plate 604, and a cutter head 605. The rotating shell 603 is provided with a handle 6031, and the rotating shell 603 rotates. The pressure plate 604 and the cutter head 605 are connected to the first half shell 601 and the second half shell 602, respectively, and are mounted on the first half shell 601 and the second half shell 602. The first half shell 601 and the second half shell 602 are equipped with a retainer 606, and the retainer 606 is provided with a mounting port 6061. The opening width of the mounting port 6061 is smaller than the diameter of the mounting port 6061. The mounting port 6061 is connected to a connecting shaft 607, and a first rotating member 608 is provided on the connecting shaft 607. When the first half shell 601 and the second half shell 602 slide on the guide plate 4, the first rotating member 608 rolls on the side of the guide plate 4.

[0038] The measuring device 7 includes a mounting plate 701, a scale 702, and a slide rod 703. The mounting plate 701 is mounted on the support plate 1, the scale 702 is set on the mounting plate 701, and the slide rod 703 slides on the two mounting plates 701. After the connecting shaft 607 is in the mounting port 6061 on the mounting tool holder 606, the mounting port 6061 limits the connecting shaft 607 to prevent the connecting shaft 607 from shaking on the mounting port 6061, and the connecting shaft 607 is not easy to detach from the mounting port 6061.

[0039] The first rotating component 608 is preferably a bearing.

[0040] See Figures 3-6 The first half-shell 601 and the second half-shell 602 are provided with an insertion port 609, and the card holder 606 is fitted into the insertion port 609.

[0041] The card holder 606 fits snugly into the socket 609, ensuring a tight fit and preventing the card holder 606 from becoming loose in the socket 609.

[0042] See Figures 3-7 The card holder 606 is provided with a protrusion 6062, and the edge of the insertion port 609 is provided with a card groove 610, and the protrusion 6062 and the card groove 610 are fitted together.

[0043] The protrusion 6062 fits into the slot 610, making the connection between the card holder 606 and the slot 610 more secure, and the card holder 606 is less likely to detach from the socket 609.

[0044] See Figure 7There are at least two protrusions 6062 on a single card holder 606, and the protrusions 6062 on a single card holder 606 are symmetrically arranged on both sides of the card holder 606.

[0045] The connection between the card holder 606 and the socket 609 is tighter to prevent the card holder 606 from wobbling on the socket 609.

[0046] See Figure 3 and Figure 4 Card slots 606 and sockets 609 are arranged in groups, and multiple groups of card slots 606 and sockets 609 are arranged on the first half shell 601 and the second half shell 602.

[0047] Each card holder 606 is connected to a connecting shaft 607, and each connecting shaft 607 is provided with a first rotating component 608. Multiple first rotating components 608 on the first half shell 601 and the second half shell 602 roll on the side of the guide plate 4, so that the entire cutting device 6 can slide better on the guide plate 4.
