[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figure 1 The present invention provides a multi-angle positioning auxiliary device for leather cutting, comprising: three support columns 1, a leather body 2 on the upper surface of the three support columns 1, a positioning structure 3 on the upper surface of the three support columns 1, and a collection structure 4 on the inner wall of the base plate 301.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The positioning structure 3 includes a base plate 301, which is fixedly connected to three support columns 1. An auxiliary groove 302 is formed inside the base plate 301, and a fixing column 303 is fixedly connected inside the auxiliary groove 302. A connecting plate 304 is fixedly connected to the upper surface of the fixing column 303.

A slip ring 309 is slidably connected to the arc surface of the limiting columns 306. A spring 310 is fitted onto the arc surface of the limiting columns 306, with both ends of the spring 310 connected to the slip ring 309 and the connecting plate 304 respectively. 4. Fixed connection: The arc surface of the limiting post 306 is movably connected to the extrusion plate 307. Several positioning rods 308 are fixedly connected to the lower surface of the extrusion plate 307. The two extrusion plates 307 are fixedly connected to the moving plate 312. The upper end of the two limiting posts 306 is fixedly connected to the top plate 320. The upper surface of the top plate 320 is fixedly connected to the connecting rod 315. The side of the connecting rod 315 away from the top plate 320 is fixedly connected to the motor 316. The output end of the motor 316 is fixedly connected to the rotating column 313. The rotating column 313 is rotatably connected to the top plate 320. The inner wall of the rotating column 313 is threaded with the lead screw 314. The end of the lead screw 314 away from the rotating column 313 is fixedly connected to the moving plate 312. The upper surface of the extrusion plate 307 is fixedly connected to the handle 317. When personnel need to cut the leather body 2, the two extrusion plates 307 can be moved to position the leather body 2, preventing it from moving during the cutting process and thus improving work efficiency. An anti-slip sleeve 318 with a hollow circular cross-section is fixedly connected to the arc surface of the handle 317. The anti-slip sleeve 318 increases the friction between the personnel's hand and the handle 317, preventing slippage during movement. A guide block 311 is fixedly connected to the lower end of the positioning rod 308. The guide block 311 guides the positioning rod 308, facilitating its sliding into the inner wall of the positioning hole 305. A protective pad 319 with a rectangular cross-section is fixedly connected to the lower surface of the extrusion plate 307. The protective pad 319 protects the leather body 2, preventing direct contact between the extrusion plate 307 and the leather body 2. The positioning rod 308 is made of stainless steel. The stainless steel rod has high strength and good wear resistance, which can prevent the positioning rod 308 from deforming during short-term use;

[0033] In the embodiments of this utility model, please refer to Figure 4 and Figure 5The collecting structure 4 includes a chute 41, which is formed on the base plate 301. A slider 42 is slidably connected to the inner wall of the chute 41. A connecting groove 43 is formed on the inner wall of the slider 42. An auxiliary block 44 is slidably connected to the inner wall of the connecting groove 43. An mounting block 45 is fixedly connected to the upper surface of the auxiliary block 44. A collecting frame 46 is fixedly connected to the side of the mounting block 45 away from the base plate 301. This allows for the collection of waste generated during the cutting process of the leather body 2. When the collecting frame 46 is full, it is easy for personnel to empty the waste, thereby improving the ease of operation. An auxiliary handle 47, which is U-shaped, is fixedly connected to the side of the collecting frame 46 away from the base plate 301. The auxiliary handle 47 allows personnel to easily move the collecting frame 46, further improving the ease of operation.

[0034] The working principle of the multi-angle positioning auxiliary device for leather cutting provided by this utility model is as follows: When a person needs to position the leather body 2, the person can first move the leather body 2 so that it is placed on the base plate 301. Then, the person uses the anti-slip sleeve 318 to rotate the handle 317. The anti-slip sleeve 318 can increase the friction between the person's hand and the handle 317, preventing slippage during the movement of the handle 317. Then, the handle 317 drives the extrusion plate 307 to rotate. The extrusion plate 307 drives the protective pad 319 and several positioning rods 308 to rotate. The positioning rods 308 drive the guide block 311 to rotate. The guide block 311 can guide the positioning rods 308, making it easier for the positioning rods 308 to slide into the inner wall of the positioning hole 305 until the two extrusion plates 307 rotate to a position that matches the leather body 2. Then, the person starts the motor 316. The output end drives the rotating column 313 to rotate, the rotating column 313 drives the lead screw 314 to move away from the motor 316, the lead screw 314 drives the moving plate 312 to move away from the motor 316, the moving plate 312 drives the two extrusion plates 307 to move downward, the extrusion plates 307 drive several positioning rods 308, protective pads 319 and handles 317 to move downward, the extrusion plates 307 drive the spring 310 to retract, wherein the positioning rod 308 is a stainless steel rod, the stainless steel rod has high strength and good wear resistance, which can prevent the positioning rod 308 from deforming during short-term use until the positioning rod 308 slides into the inner wall of the positioning hole 305. During the process of the positioning rod 308 sliding in the inner wall of the positioning hole 305, until the two protective pads 319 abut against the leather body 2, wherein the protective pads 319 can protect the leather body 2 and prevent the extrusion plate 307 from directly contacting the leather body 2.

[0035] Additionally, when personnel are cutting the leather body 2, they can first move the auxiliary handle 47, which moves the collection frame 46. The auxiliary handle 47 facilitates the movement of the collection frame 46, improving operational convenience. Then, the collection frame 46 moves the mounting block 45, which in turn moves the auxiliary block 44. The auxiliary block 44 then moves the slider 42, which slides along the inner wall of the groove 41 until the collection frame 46 reaches the appropriate position. Personnel can then collect the cut waste material by placing it into the inner wall of the collection frame 46. When the collection frame 46 is full, personnel can move the auxiliary handle 47 upwards, which moves the collection frame 46 upwards. The collection frame 46 then moves the waste material and the mounting block 45 upwards, and the mounting block 45 moves the auxiliary block 44 upwards until the auxiliary block 44 completely slides out of the inner wall of the connecting groove 43. At this point, personnel can empty the waste material from the collection frame 46.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
