Description

Technical Field

[0001] This utility model relates to the field of hose cutting technology, and in particular to a PVC hose cutting device. Background Technology

[0002] PVC hoses are widely used in agricultural irrigation, industrial fluid transportation, building drainage, and domestic water supply due to their flexibility, corrosion resistance, and low cost. In practical applications, hoses often need to be precisely cut according to installation requirements. Traditional cutting tools (such as utility knives and ordinary hand saws) suffer from uneven cuts and low efficiency, while specialized dovetail saws, with their unique tooth design (such as dovetail-shaped tooth distribution), can achieve fast cutting with smooth cuts and are gradually becoming the mainstream tool.

[0003] Most commercially available dovetail saws currently use a fixed design, consisting of a one-piece molded saw blade and a rigid handle. While this structure ensures stability during cutting, it has significant drawbacks: inconvenient storage (the saw blade is typically 30-50cm long, making it difficult to fit into standard toolboxes or confined workspaces, and it is prone to tangling with other tools during transport); safety hazards (exposed saw teeth can easily scratch the operator or damage other items during transportation or storage); and reduced durability (long-term exposure of the saw teeth makes them susceptible to deformation from external impacts, affecting cutting accuracy). To address these issues, we propose a PVC flexible hose cutting device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PVC hose cutting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A PVC hose cutting device includes a handle and a saw. A rectangular groove is laterally formed at the bottom left side of the handle, and a support rail is inserted inside the rectangular groove. A fixing component is fixedly inserted inside the support rail. Another set of rectangular grooves is formed at the top of the handle, and a threaded rod is inserted inside the top rectangular groove. The bottom end of the threaded rod is fixedly connected to a fixing frame, and the bottom end of the fixing frame is fixedly connected to the top end of the fixing component. A saw is inserted inside the left side of the support rail, and the saw is fixedly connected to the support rail by screws.

[0007] Preferably, the surface of the threaded rod is fitted with a threaded sleeve, and the bottom end of the threaded sleeve is fixedly connected with a fixing ring, the diameter of which is greater than the width of the rectangular groove at the top of the handle.

[0008] Preferably, a fixing rod is horizontally fixed inside the fixing frame, and a movable block is sleeved on the surface of the fixing rod. The two ends of the movable block are hinged to elastic cards. Limiting grooves are evenly formed on both sides of the rectangular slide groove at the top of the handle. The elastic card is inserted into the limiting groove. The elastic card has a V-shaped structure. When it is squeezed by external force, it deforms and stores elastic potential energy. After the external force is released, it quickly returns to its original shape. The movement trajectory of the component is controlled by the deformation direction to realize the positioning function of unfolding / folding. The thin-plate design occupies little space and can be embedded in narrow mechanical gaps.

[0009] Preferably, springs are symmetrically sleeved on both sides of the fixing rod, and one end of the spring is fixedly connected to the inner wall of the fixing frame, while the other end of the spring is fixedly connected to the side wall of the movable block.

[0010] Preferably, the right side surface of the handle has a rectangular opening, and the edges of the rectangle are chamfered.

[0011] Preferably, an L-shaped groove is provided on the inner right side of the handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device has an inner cavity inside the handle. By pulling the threaded rod, the saw can be moved into the inner cavity, thus serving a storage function. When the device is not in use, the saw can be stored inside for protection, solving the problems of inconvenient storage, safety hazards, and reduced durability, thereby improving the practicality of the device.

[0014] 2. This device features a limiting groove on the inner wall of the handle, into which an elastic card is inserted to limit the movement of the cutter before fixing it. This facilitates the movement of the threaded sleeve to contact the top of the handle and complete the fixing process, thus improving the practicality of the device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A PVC hose cutting device includes a handle 1 and a saw 2. A rectangular groove is horizontally opened at the bottom left side of the handle 1, and a support rail 3 is inserted inside the rectangular groove. A fixing component 4 is fixedly inserted inside the support rail 3. Another set of rectangular grooves is opened at the top of the handle 1, and a threaded rod 5 is inserted inside the top rectangular groove. The bottom end of the threaded rod 5 is fixedly connected to a fixing frame 8, and the bottom end of the fixing frame 8 is fixedly connected to the top end of the fixing component 4. The saw 2 is inserted inside the left side of the support rail 3, and the saw 2 is fixedly connected to the support rail 3 by screws.

[0022] Furthermore, refer to Figure 2 It can be seen that the surface of the threaded rod 5 is fitted with a threaded sleeve 6, and the bottom end of the threaded sleeve 6 is fixedly connected with a fixing ring. The diameter of the fixing ring is larger than the width of the rectangular groove at the top of the handle 1. During use, rotating the threaded sleeve 6 pushes the fixing ring to abut against the top of the handle 1, thereby achieving the function of limiting the fixed frame 8.

[0023] Furthermore, refer to Figure 2 It can be seen that a fixing rod 9 is horizontally fixed inside the fixed frame 8, and a movable block 11 is sleeved on the surface of the fixing rod 9. The two ends of the movable block 11 are hinged to elastic cards 7. The inner walls of the rectangular slide groove at the top of the handle 1 are evenly divided into limit grooves. The elastic card 7 is inserted into the limit groove. During use, the elastic card 7 can achieve the function of limiting, preventing the fixed frame 8 from shaking and facilitating auxiliary fixation.

[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that springs 10 are symmetrically sleeved on both sides of the fixing rod 9, and one end of the spring 10 is fixedly connected to the inner wall of the fixing frame 8, and the other end of the spring 10 is fixedly connected to the side wall of the movable block 11. During use, the elastic force of the spring 10 itself helps to push the elastic card 7 to reset and insert it into the inside of the limiting groove to achieve fixation.

[0025] Furthermore, refer to Figure 4 It can be seen that a rectangular opening is provided on the right side surface of the handle 1, and the edges of the rectangle are chamfered. During use, it is convenient for workers to hold the handle, and the chamfering can also play a protective role in preventing injury from friction between fingers.

[0026] Furthermore, refer to Figure 4 It can be seen that there is an L-shaped groove on the inside right side of the handle 1. During use, the elastic card 7 moves and abuts against the inner wall of the L-shaped groove, thereby achieving the function of limiting the position.

[0027] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, when the worker is cutting the PVC hose, according to the attached... Figure 2 As shown, first rotate the threaded sleeve 6. The threaded sleeve 6 moves upward along the surface of the threaded rod 5, and the fixing ring moves away from the surface of the handle 1. The fixing frame 8 is released from its limit. At this time, pull the threaded sleeve 6 to the left. The movement of the threaded sleeve 6 drives the elastic card 7 to move. The movement of the elastic card 7 drives the support guide rail 3 to move. The support guide rail 3 drives the saw piece 2 to move. When the saw piece 2 has completely moved out of the interior of the handle 1, rotate the threaded sleeve 6 in the opposite direction. The threaded sleeve 6 moves along the surface of the threaded rod 5 and pushes the fixing ring to reset. At this time, the fixing frame 8 is limited, and the saw piece 2 is fixed, which facilitates the use of the device. When the saw piece 2 needs to be replaced, use a screwdriver to remove the screw connecting the saw piece 2 and the support guide rail 3. After replacing the saw piece 2, reconnect the saw piece 2 and the support guide rail 3 with screws. When the work is completed, repeat the above operation and pull the saw piece 2 to reset. The operation is completed. The above is the complete working principle of this utility model.
