DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a plastic product processing tool, comprising a tool body 1, a U-shaped tool holder 2 and a quick-release structure 3, the top end of the tool body 1 is inserted into the inner side of the U-shaped tool holder 2, and the quick-release structure 3 is arranged between the tool body 1 and the U-shaped tool holder 2;

[0019] The quick-release structure 3 includes a through-block 31, a socket 32, a through-hole 33, a cylindrical groove 34, a cylindrical shaft block 35 and a limit baffle 36. The top surface of the tool body 1 is penetrated with a through-hole 33 corresponding to the through-block 31, and the two side surfaces of the U-shaped tool holder 2 are penetrated with sockets 32 corresponding to the through-block 31. The through-block 31 is inserted into the socket 32 ​​and penetrates the through-hole 33. The two ends of the through-block 31 are respectively located in the two sockets 32 on the two side surfaces of the U-shaped tool holder 2. The through-block 31 can connect the tool body 1 and the U-shaped tool holder 2 together. The top of the U-shaped tool holder 2 is penetrated with a cylindrical groove 34, and a cylindrical shaft block 35 is rotatably installed in the cylindrical groove 34. The two ends of the cylindrical shaft block 35 are respectively penetrated to the U-shaped tool holder The two side surfaces of the rack 2 and the two side surfaces of the U-shaped tool holder 2 are both provided with limit baffles 36, and the ends of the cylindrical shaft block 35 are fixedly connected to the limit baffles 36, and the bottom ends of the limit baffles 36 cover the insertion hole 32, which can stably block and limit the penetration block 31 to ensure the installation stability of the tool body 1. The quick-release structure 3 also includes an inner groove 37 opened inside the cylindrical shaft block 35, and a spring 38 and a hemispherical telescopic block 39 are arranged in the inner groove 37. The hemispherical telescopic block 39 is movably installed in the inner groove 37 through the spring 38. A circular card hole 310 corresponding to the hemispherical telescopic card block 39 is opened on the top surface of the U-shaped tool holder 2, and the top end of the hemispherical telescopic card block 39 pops out into the circular card hole 310, which can be used for the circular card hole 310. The cylindrical shaft block 35 has the effect of locking and limiting, ensuring that the limiting baffle 36 can stably block the penetration block 31. If the tool body 1 is to be removed later, it is only necessary to push the two limiting baffles 36 with force to make the cylindrical shaft block 35 rotate in the cylindrical groove 34, and make the top of the hemispherical telescopic block 39 gradually squeezed into the inner groove 37 until the top of the hemispherical telescopic block 39 is squeezed out of the circular clamping hole 310, so that the cylindrical shaft block 35 and the limiting baffle 36 can rotate smoothly, thereby rotating the limiting baffle 36 away from the opening of the socket 32. At this time, the penetration block 31 can be pulled out, and the tool body 1 can be directly disassembled from the U-shaped tool holder 2. When the tool body 1 is installed later, it is only necessary to first remove the tool The top of the tool body 1 is inserted into the inner side of the U-shaped tool holder 2, and the insertion hole 32 and the through hole 33 are aligned, and then the through block 31 is inserted into the insertion hole 32 and passes through the through hole 33, so that the tool body 1 and the U-shaped tool holder 2 can be connected together. At this time, the limit baffle 36 is rotated, and the hemispherical telescopic block 39 can be rotated to the circular clamping hole 310 together with the cylindrical shaft block 35. At this time, the top of the hemispherical telescopic block 39 will be inserted into the circular clamping hole 310 under the push of the spring 38, thereby engaging and limiting the cylindrical shaft block 35 and the limit baffle 36. At this time, the bottom end of the limit baffle 36 can cover and block the insertion hole 32, thereby blocking and limiting the through block 31, thereby ensuring the installation stability of the tool body 1.

[0020] Among them, the bottom end of the spring 38 is fixed to the bottom inner wall of the inner groove 37, and the top end of the spring 38 is welded and fixed to the bottom surface of the hemispherical telescopic block 39 to ensure the installation stability of the spring 38. The bottom end of the circular card hole 310 is connected to the cylindrical groove 34.

[0021] Among them, the U-shaped tool holder 2 is slidably installed at the bottom of the base plate 4, and a cylinder 5 is installed on the top of the base plate 4, and the piston rod at the bottom end of the cylinder 5 passes through the bottom of the base plate 4 and is fixed to the U-shaped tool holder 2. Guide plates 21 are welded and fixed to the left and right end surfaces of the U-shaped tool holder 2, and two guide rods 41 corresponding to the guide plates 21 are provided at the bottom of the base plate 4, and the guide plates 21 are slidably sleeved on the guide rods 41. After the cylinder 5 is started, the U-shaped tool holder 2 will move down with the tool body 1, so that the bottom end of the tool body 1 contacts the plastic product, and the cutting processing of the plastic product can be realized.

[0022] Example 2

[0023] See also Figures 1 to 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that it can assist the positioning of the tool body 1 during the early installation of the tool body 1.

[0024] Specifically, it also includes a positioning structure, which is arranged between the tool body 1 and the U-shaped tool holder 2. The positioning structure includes a rubber seat 23, a strip positioning protrusion 24 and a strip positioning groove 11. Rubber seats 23 are installed on the inner walls of both sides of the U-shaped tool holder 2. The surface of the rubber seat 23 is provided with a strip positioning protrusion 24. The top surface of the tool body 1 is provided with a strip positioning groove 11 corresponding to the strip positioning protrusion 24. The strip positioning protrusion 24 is embedded in the strip positioning groove 11. When installing the tool body 1, the operator will push the top of the tool body 1 into the inner side of the U-shaped tool holder 2 and align the through hole 33 with the insertion hole 32. At the same time, the strip positioning protrusion 24 will be squeezed into the strip positioning groove 11, thereby playing a certain auxiliary positioning effect on the tool body 1. At this time, it is more convenient for the operator to perform the penetration operation of the penetration block 31, preventing the insertion hole 32 and the through hole 33 from being offset during the penetration process of the penetration block 31.

[0025] Among them, the inner walls on both sides of the U-shaped tool holder 2 are provided with embedding grooves 22, and one end of the rubber seat 23 is embedded and installed in the embedding groove 22 to provide stable installation of the rubber seat 23. The rubber seat 23 and the strip-shaped positioning protrusion 24 are an integrated structure, both of which are made of rubber material. At the same time, a circular through hole is also opened on the surface of the rubber seat 23, so that the strip-shaped positioning protrusion 24 has sufficient deformation space when squeezed.

[0026] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
