[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-4 As shown, this utility model provides a technical solution: a retractable and foldable protective railing for the transmission belt of a circular saw, including a base plate 1, and further comprising:

[0034] The protective component 3 includes a first guide groove 31 set on the top of the base plate 1. A clamping rod 32 is slidably arranged in the first guide groove 31. A knob 36 is set on the outside of the first guide groove 31. A second guide groove 33 is opened on the top of each clamping rod 32. A protective rail body 34 is slidably arranged in the second guide groove 33. When the protective component 3 is working, the first guide groove 31 provides sliding guidance for the clamping rod 32. When the clamping rod 32 is operated to clamp inward, it drives the protective rail body 34 in the second guide groove 33 to expand and unfold. At the same time, through structural connection, the dustproof plate 35 is pulled upward. The protective rail body 34 blocks danger and the dustproof plate 35 blocks debris, achieving the dual effect of protection and dust prevention.

[0035] The blowing assembly 7 includes a sliding groove 71 located on the top of the base plate 1 away from the protective assembly 3. A movable groove 72 is slidably disposed on the top of the sliding groove 71, and a blowing fan 73 is slidably disposed on the top of the movable groove 72. When the blowing assembly 7 is working, the sliding groove 71 provides a sliding path for the movable groove 72. The movable groove 72 carries the blowing fan 73 and can adjust its lateral position. The blowing fan 73 changes its longitudinal position by sliding, flexibly blowing away waste and cooling it.

[0036] Furthermore, such as Figures 1-3 As shown: A dustproof plate 35 is provided at the bottom of the guardrail body 34. The top of the dustproof plate 35 is provided with a slot. The dustproof plate 35 is slidably connected to the guardrail body 34 through the slot. When the guardrail body 34 is unfolded or retracted, the dustproof plate 35 slides with the guardrail body 34 through the top slot and rises and falls synchronously with the guardrail to block the debris generated by cutting and achieve the dustproof protection effect.

[0037] The above solutions also have equipment storage issues, such as... Figure 3 As shown: In this solution, a storage groove 37 is provided on one side of the base plate 1. The base plate 1 is slidably connected to the dustproof plate 35 through the storage groove 37. The storage groove 37 on one side of the base plate 1 and the dustproof plate 35 are slidably engaged. The dustproof plate 35 can be pushed into the storage groove 37 for storage, which makes it easier to save space when the protective component 3 is folded.

[0038] Working principle: such as Figures 1-4 As shown, the support box 2 at the bottom of the base plate 1 provides stable support to ensure smooth operation of the equipment; the feed bin 8 at the top of the base plate 1 is used to place the workpiece, and the circular saw body 5 performs cutting operations in the feed bin 8. The waste generated from cutting falls directly into the feed bin 8 and is guided to the waste bin 6 at the bottom for centralized collection. The baffle plate 4 on the side of the base plate 1 away from the feed bin 8 not only prevents excessive movement of the workpiece, but also intercepts the waste that splashes during the cutting process. Together with the waste bin 6, it achieves efficient blocking and collection of waste. In the protective component 3, the first guide groove 31 provides sliding guidance for the clamping rod 32. After the knob 36 is loosened, the clamping rod 32 is operated to clamp inward, which drives the protective rail body 34 in the second guide groove 33 to expand and unfold. At the same time, the structure is linked. Pulling the dustproof plate 35 upwards, the guardrail body 34 forms a physical barrier to prevent the operator from coming into contact with the transmission belt. The dustproof plate 35 slides and rises and falls with the guardrail body 34 through the top slot, blocking the debris generated by cutting and achieving the dual effect of protection and dust prevention. When not in use, the dustproof plate 35 can be pushed into the storage slot 37 on one side of the base plate 1 for storage, saving the folding space of the protective component 3. In the blowing component 7, the sliding slot 71 provides a lateral sliding path for the moving slot 72. The moving slot 72 carries the blowing fan 73 and can adjust its lateral position. The blowing fan 73 slides longitudinally on the moving slot 72 to change its position. By flexibly adjusting the blowing angle and position, the waste in the working area is quickly removed and the equipment is cooled.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
