[0014] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model.

[0015] like Figure 1 and Figure 2 As shown, this specific embodiment adopts the following technical scheme: it includes a tooling body 1, a replacement positioning base plate 2, a clamping plate 3 and a positioning plate 4; a replacement positioning base plate 2 is movably provided in the slot in the tooling body 1, and a plurality of positioning grooves 2-1 with a trapezoidal cross section are provided on the upper surface of the replacement positioning base plate 2, and a product 13 is arranged in the positioning groove 2-1, and a reference panel 12 is fixed behind the slot in the tooling body 1, and the rear end of the product 13 is arranged in abutment with the reference panel 12; the clamping plate 3 and the positioning plate 4 are both movably mounted above the tooling body 1, and the opening on the positioning plate 4 is movably provided. A locating pin 5 is provided, and the lower end of the locating pin 5 is movably connected to the circular hole in the product 13; the two ends of the clamping plate 3 are installed on the tooling body 1 by means of guide studs 6 and locking nuts 8, and a spring 7 is sleeved on the guide studs 6 at a position below the two ends of the clamping plate 3; a number of pressing pins 9 corresponding to the product 13 are movably provided in the clamping plate 3; the upper end of the pressing pin 9 is threadedly connected with an adjusting nut 10, and a spring 2 11 is sleeved on the pressing pin 9 at a position below the clamping plate 3, and the two ends of the spring 2 11 are respectively set in contact with the lower end cap of the pressing pin 9 and the bottom surface of the clamping plate 3.

[0016] When using the utility model, first place the product 13 in the positioning groove 2-1, then place the replacement positioning base plate 2 together with the product 13 into the slot in the tooling body 1, and make the rear end of the product 13 abut against the reference panel 12; then place the positioning plate 4 above the product 13 (the two ends of the positioning plate 4 are mounted on the upper edges of both sides of the tooling body 1), and make the lower end of the positioning pin 5 dock with the circular hole in the product 13, so as to adjust the circular hole of the product 13 to face upward, and after all products 13 are adjusted in turn, adjust the adjusting nut 10 on the clamping plate 3 to adjust the clamping stroke of a single pressure pin 9 to ensure uniform force; then rotate the locking nut 8 on the top of the guide stud 6 to push the clamping plate 3 down, realize the clamping operation on the product 13, and finally start wire cutting of the waist-shaped groove.
