Description

Technical Field

[0001] The utility model belongs to the field of blade structures, and particularly relates to a quick-installation safety blade. Background Art

[0002] As the last wire-cutting tool in the manual zongzi-wrapping production process, the wire-cutting tool is an essential part. In current production, in traditional wire cutting, a utility knife is fixed on the workbench, and the wire is cut by the direct action of the wire and the blade. The cutting edges of the previously used wire-cutting tools are directly exposed, which is not only vulnerable to corrosion and oil stains, but also poses a major safety hazard. After the zongzi is wrapped and the wire is tied, the worker needs to cut the wire on the wire reel. In this operation, due to the operator's long-term repetition of a single wire-cutting action, it is easy to be in a fatigued working state, and at the same time, it is extremely easy to be scratched by the exposed cutting edge, even causing serious safety accidents.

[0019] Preferred embodiment.

[0020] This embodiment provides a quick - installation safety blade 130, which includes a fixed seat, a tool holder and a blade 130. The tool holder is arranged at the upper end of the fixed seat. The tool holder includes a tool rest 110, a first support plate 120 and a first cylinder 140. The tool rest 110 is arranged at the upper end of the first support plate 120. The tool rest 110 is C - shaped. The blade 130 is arranged in the middle of the C - shaped opening of the tool rest 110. The first cylinder 140 is arranged at the lower end of the first support plate 120. The fixed seat includes a second support plate 210 and a second cylinder 220. The second cylinder 220 is arranged at the upper end of the second support plate 210. The first cylinder 140 matches the second cylinder 220.

[0021] Furthermore, a first installation cylinder 150 is arranged inside the first cylinder 140. A first spring 170 and a first ejector rod 160 are arranged inside the first installation cylinder 150. One end of the first spring 170 is connected to the first ejector rod 160, and the other end of the first spring 170 is connected to the first cylinder 140. A first through - hole 141 is arranged at the lower end of the first cylinder 140. The first through - hole 141 matches the first installation cylinder 150. A first positioning hole 221 is arranged at the lower end of the second cylinder 220. The first positioning hole 221 matches the first ejector rod 160.

[0022] Furthermore, a first chute 222 is arranged at the upper end of the second cylinder 220. The upper end of the first chute 222 is connected to the opening of the second cylinder 220. The lower end of the first chute 222 is connected to the first positioning hole 221. The depth of the first chute 222 gradually increases from top to bottom.

[0023] Further, the fixing base includes a third support plate 230. A first guide rod 240 is provided at the lower end of the second support plate 210. A first guide hole is provided at one corner of the third support plate 230. The first guide hole matches the first guide rod 240. Second through holes 231 are provided at the other three corners of the third support plate 230. Three first threaded holes 211 are provided on the second support plate 210. The first threaded holes 211 correspond to the second through holes 231 one by one. The fixing base includes three first screw rods 260. One end of the first screw rod 260 passes through the second through hole 231 and is connected to the first threaded hole 211.

[0024] Further, the fixing base includes a second spring 250 and a first baffle 241. The first baffle 241 is arranged at the lower end of the first guide rod 240. The second spring 250 is sleeved on the first guide rod 240. The second spring 250 is located between the first baffle 241 and the third support plate 230.

[0025] Working principle: First, place the fixing base on one side of the workbench. Place the second support plate 210 on the upper end of the support guardrail of the workbench. Then rotate the third support plate 230 to the lower end of the support guardrail. The second spring 250 presses against the third support plate 230 to closely adhere to the lower surface of the support guardrail. Then use the first screw rod 260 to pass through the second through hole 231 and connect it to the first threaded hole 211 to fix the fixing base on the support guardrail. Then place the tool holder on the upper end of the fixing base. Insert the first cylinder 140 into the second cylinder 220. The first spring 170 presses against the first ejector rod 160. The first ejector rod 160 is ejected out of the first through hole 141 and the first ejector rod 160 is moved downward along the first chute 222, so that the first ejector rod 160 is snapped into the first positioning hole 221, thereby fixing the tool holder. Among them, the depth of the first chute 222 gradually increases from top to bottom, which can prevent the tool holder from shaking up and down. With the limitation of the first positioning hole 221, the stability of the tool holder can be ensured. At the same time, when the tool holder needs to be removed, a certain force can be applied to take it out. Finally, through the blade 130 provided on the tool rest 110, the wire cutting action can be completed.
