Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, specifically a jigsaw. Background Technology

[0002] A jigsaw can cut curved paths on sheet metal. When cutting near the edge, if there is an obstruction next to the cutting position, the saw blade often cannot reach the intended cutting point. This is because the distance between the front end of the bottom support plate of the jigsaw and the saw blade is too large. When the support plate comes into contact with the obstruction, the machine cannot continue to move forward. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a jigsaw.

[0004] The objective of this utility model can be achieved through the following technical solutions: A jigsaw, comprising: The main body has a cutting saw blade; A support assembly is mounted on the main body. The support assembly includes a support plate and two support portions slidably disposed on the support plate. The two support portions are disposed on both sides of the support plate, and the two support portions and the support plate form an opening through which the cutting saw blade passes. The support portions are connected to the support plate via an elastic component, wherein the support portions are capable of moving back and forth in the cutting direction of the cutting saw blade.

[0005] In the aforementioned jigsaw, a guide channel is provided on the support plate, and a sliding part is provided on the support portion, the sliding part passing through the guide channel.

[0006] In the above-mentioned jigsaw, the elastic component is a tension spring, a first connecting part is provided on the free end of the sliding part, a second connecting part is provided on the support plate, one end of the tension spring is fixedly connected to the first connecting part, and the other end of the tension spring is fixedly connected to the second connecting part.

[0007] In the above-mentioned jigsaw, the end of the sliding part is provided with a limiting part, which can abut against the outer end wall of the guide channel.

[0008] In the above-mentioned jigsaw, the main body includes a housing portion, the housing portion having a grip portion, the tension spring being located below the grip portion, and the tension spring being located within the orthographic projection of the housing portion.

[0009] In the aforementioned jigsaw, the tension spring is located on the side of the support plate away from the cutting saw blade.

[0010] In the aforementioned jigsaw, the support portion is provided with a movement indicator with a two-way arrow.

[0011] Compared with the prior art, this application has the following advantages: Traditional jigsaws, due to their fixed support plate, cannot advance when encountering obstructions, resulting in the saw blade not being able to cut to the intended position. However, the support of this jigsaw is slidable and equipped with elastic components, which can avoid obstructions and allow the saw blade to smoothly reach the intended cutting point near the edge, greatly expanding the cutting range of the jigsaw in complex working conditions.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0014] like Figures 1 to 3 As shown, a jigsaw includes: a main body 2 and a support assembly 3. The main body 2 has a cutting saw blade 21. The support assembly 3 is mounted on the main body 2 and includes a support plate 31 and two support parts 32 slidably disposed on the support plate 31. The two support parts 32 are disposed on both sides of the support plate 31, and the two support parts 32 and the support plate 31 form an opening 4 through which the cutting saw blade 21 passes. The support parts 32 are connected to the support plate 31 through an elastic assembly 5. The support parts 32 are capable of moving back and forth in the cutting direction of the cutting saw blade 21.

[0015] In this application, the cutting saw blade 21 cuts materials such as wood and plastic through reciprocating motion, while the support component 3, as a key auxiliary structure, provides a stable support foundation for the whole machine cutting.

[0016] Two support parts 32 are distributed on both sides of the support plate 31, and together with the support plate 31, they form an opening 4 for the saw blade to pass through. When cutting near the edge and where there is an obstruction, if the support plate 31 touches the obstruction during its advancement, as the machine continues to apply force in the cutting direction, the obstruction will generate a reverse thrust on one or both support parts 32. At this time, the support part 32, through its sliding connection with the support plate 31, retracts inward along the cutting direction, allowing the cutting saw blade 21 to get closer to the obstruction. When the cutting is completed and the machine moves away from the obstruction or the thrust disappears, the stretched elastic component 5 will drive the support part 32 to move in the opposite direction and return to its initial position.

[0017] Traditional jigsaws, due to the fixed support plate 31, cannot advance after encountering an obstruction, resulting in the saw blade not being able to cut to the predetermined position. However, the support part 32 of this jigsaw is slidable and, in conjunction with the elastic component 5, can avoid obstructions, allowing the saw blade to smoothly reach the predetermined cutting point near the edge, greatly expanding the cutting range of the jigsaw in complex working conditions.

[0018] Specifically, the support plate 31 is provided with a guide channel 311, and the support part 32 has a sliding part 321, which passes through the guide channel 311.

[0019] The guide channel 311 provides a unique and fixed movement path for the sliding part 321 of the support part 32, effectively restricting the support part 32 to only reciprocate linearly along the cutting direction of the cutting saw blade 21, and preventing the support part 32 from shifting laterally, tilting or getting stuck when under force.

[0020] Specifically, the elastic component 5 is a tension spring, a first connecting part 3211 is provided on the free end of the sliding part 321, a second connecting part 312 is provided on the support plate 31, one end of the tension spring is fixedly connected to the first connecting part 3211, and the other end of the tension spring is fixedly connected to the second connecting part 312.

[0021] The tension characteristics of the tension spring can generate a continuous and predictable reset traction force on the support part 32. When the support part 32 moves inward along the guide channel 311 under the thrust of the obstruction, the tension spring is stretched synchronously and stores elastic potential energy; once the thrust disappears, the return force of the tension spring will drive the sliding part 321 to smoothly reset along the guide channel 311, which helps the support part 32 to accurately return to the initial support position each time, and avoids the support stability of subsequent cutting due to reset deviation.

[0022] Specifically, the end of the sliding part 321 is provided with a limiting part 3212, which can abut against the outer end wall of the guide channel 311.

[0023] When the tension spring resets the support part 32, the limiting part 3212 can form a rigid abutment with the outer end wall of the guide channel 311, effectively limiting the extreme position of the support part 32 sliding outward along the cutting direction, and ensuring that the two support parts 32 always maintain a symmetrical and uniform initial support posture.

[0024] Furthermore, the first connecting part 3211 is provided on the limiting part 3212.

[0025] Specifically, the main body 2 includes a housing portion 22, which has a grip portion 221. A tension spring is located below the grip portion 221 and is located within the orthographic projection of the housing portion 22.

[0026] The design ensures that during use, the hand should be held as far away from the tension spring as possible while gripping the grip part 221 to avoid injury from contact with the tension spring.

[0027] Specifically, the tension spring is located on the side of the support plate 31 away from the cutting saw blade 21.

[0028] Specifically, the support part 32 is provided with a movement indicator 322 with a two-way arrow.

[0029] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0030] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0031] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0032] The specific embodiments described herein are merely illustrative examples of this utility model.
