Description

TECHNICAL AREA

[0001] The present utility model relates to a saw, in particular a length-adjustable multi-functional saw. STATE OF THE ART

[0002] Conventional saws are generally limited in their multifunctionality and length adjustability. The blade length is typically fixed and cannot be adapted to different tasks. In practice, various work scenarios often require blades of different lengths. For example, longer blades are suitable for large cuts, while shorter blades are better for fine work. The fixed blade length restricts the saw's applications. To perform various tasks, users must purchase multiple saws or blades of different lengths, increasing operating costs. The blade tension of conventional saws is usually adjusted manually, or the blade is secured using a simple locking mechanism.However, with long-term use, these methods can easily lead to loose or unstable mounting. Loose saw blades impair the cutting accuracy and efficiency of the saw and increase operational uncertainty. In high-precision or high-intensity cutting processes, loose saw blades can even pose a safety risk. CONTENTS OF THE PRESENT USE SAMPLE

[0003] The technical problem to be solved by the present utility model is to provide a length-adjustable multi-functional saw in order to remedy an existing problem in the prior art.

[0004] The length-adjustable multi-function saw according to the present utility model is realized by a technical solution in which the multi-function saw comprises a saw body and a saw blade;

[0005] The saw body is provided with a mounting seat at one end, and a length adjustment structure is provided at the other end of the saw body; one end of the saw blade is arranged on the mounting seat, and the other end of the saw blade is arranged on the mounting end of the length adjustment structure.

[0006] A preferred technical solution consists in the length adjustment structure being provided on a mounting groove at the other end of the saw body; the length adjustment structure comprising a movable block and a threaded rod; The mounting groove is provided with a guide groove on one side; and the movable block is provided through the guide groove; the movable block is provided with a guide hole, and the threaded end of the threaded rod is arranged in the guide hole; the movable block is provided with a slot, and an adjusting screw is provided in the slot; the adjusting screw is connected to the threaded end of the threaded rod, and the saw blade is attached to the movable block, and by turning the adjusting screw the movable block is driven to extend and retract in order to adapt to the length of the saw blade.

[0007] A preferred technical solution consists in a clamping seat being rotatably provided on a rotary groove at the other end of the saw body, and a connecting rod being attached to the inside of the clamping seat by means of a rotary shaft, and one end of the connecting rod being rotatably connected to the threaded rod, so that the saw blade is clamped by turning the clamping seat.

[0008] A preferred technical solution is to provide the saw body with a grip groove to facilitate handling of the saw body.

[0009] A preferred technical solution is to provide the mounting seat and the movable block each with a positioning post in a different orientation, and to attach the saw blade to the positioning post, so that mounting in a different position is possible.

[0010] The advantageous effects of the present utility model are as follows: In the present utility model, the movable block and the threaded rod are arranged so that the length of the saw blade can be adjusted within a certain range according to actual needs in order to meet the size requirements of different saw blades; by turning the adjusting screw, the movable block is driven to extend and retract in order to enable precise adjustment of the length of the saw blade and to improve the usability of the saw;

[0011] In the present utility model, the arrangement of the clamping seat and connecting rod at the opposite end of the saw body makes it possible to effectively tension the saw blade and ensure that the saw blade always remains in a tensioned state. This prevents the saw blade from loosening during use, which would impair the cutting performance. BRIEF DESCRIPTION OF THE DRAWING

[0014] With the exception of mutually exclusive features and / or steps, all features or steps of the procedure or process disclosed in this description can be combined in any way.

[0015] As in Fig. 1 to Fig. Figure 3 shows a length-adjustable multi-function saw of the present utility model comprising: a saw body 1 and a saw blade 13;

[0016] The saw body 1 is provided at one end with a mounting seat 2, and at the other end of the saw body 1 a length adjustment structure is provided; one end of the saw blade 13 is arranged on the mounting seat 2, and the other end of the saw blade 13 is arranged on the mounting end of the length adjustment structure.

[0017] In the present embodiment, the length adjustment structure is provided on a mounting groove 3 at the other end of the saw body 1 to adapt to the length of the saw blade; the length adjustment structure comprises a movable block 4 and a threaded rod 5;

[0018] The mounting groove 3 is provided on one side with a guide groove 6; and the movable block 4 is provided through the guide groove 6; the movable block 4 is provided with a guide hole 7, and the threaded end of the threaded rod 5 is arranged in the guide hole 7; the movable block 4 is provided with a slot 8, and an adjusting screw 9 is provided in the slot 8; the adjusting screw 9 is connected to the threaded end of the threaded rod 5, and the saw blade 13 is attached to the movable block 4, and by turning the adjusting screw 9 the movable block 4 is driven to extend and retract in order to adapt to the length of the saw blade 13.

[0019] In order to tension the saw blade, in the present embodiment a clamping seat 14 is rotatably provided on a rotary groove 10 at the other end of the saw body 1, and a connecting rod 15 is attached to the inside of the clamping seat by means of a rotary shaft 16, and one end of the connecting rod is rotatably connected to the threaded rod 5, so that the saw blade 13 is tensioned by turning the clamping seat.

[0020] To facilitate handling of the saw, the saw body 1 in the present embodiment is provided with a grip groove 11. This makes handling the saw body 1 easier.

[0021] To facilitate the mounting of the saw blade at different angles, in the present embodiment the mounting seat 2 and the movable block 4 are each provided with a positioning post 12 in different orientations, and the saw blade 13 is attached to the positioning post 12, so that mounting in a different position is possible.

[0022] In the present utility model, the movable block and the threaded rod are arranged in such a way that the length of the saw blade can be adjusted within a certain range according to actual needs in order to meet the size requirements of different saw blades;

[0023] Turning the adjusting screw drives the movable block to extend or retract, allowing for precise adjustment of the saw blade length and improving the saw's usability. Positioning the clamping seat and connecting rod at the other end of the saw body effectively tensions the saw blade, ensuring it remains under tension at all times. This prevents the saw blade from loosening during use, which would impair cutting performance.

[0024] The foregoing merely represents one specific embodiment of the present utility model. However, the scope of protection of the present utility model is not limited thereto. All modifications or replacements not resulting from creative work should be covered by the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be subject to the scope of protection limited by the claims.
