[0030] In this embodiment, the PIN part 9 is in a columnar structure as a whole. In order to better fix the PIN part 9 and allow the inner diameter of the PIN part 9 to vary within a certain range, in this embodiment, the fixing groove 4 is a V-shaped groove.

[0031] In this embodiment, one end of the PIN part 9 is plugged into the fixing hole 2, and the other end is fixed by a pressing plate assembly. The pressing plate assembly can simultaneously press the other ends of multiple PIN parts 9 downward to achieve a batch fixing effect.

[0032] Specifically, the pressure plate assembly includes a connecting seat 5 fixedly disposed on the base 3, a cantilever pressure plate 6 rotatably connected to the connecting seat 5, a buckle 7 rotatably connected to the base 3, and a clamping assembly 8 disposed on the cantilever pressure plate 6; wherein the buckle 7 is an elastic buckle.

[0033] In this embodiment, the connection seat 5 and the buckle 7 are respectively fixed to the two sides of the base 3, so that one end of the cantilever pressure plate 6 can rotate around the connection seat 5, and the other end can be fixed by the buckle 7.

[0034] In this embodiment, the above-mentioned clamping assembly 8 includes a cantilever back plate 81 arranged on the upper side of the cantilever pressure plate 6, and the cantilever back plate 81 is connected to the cantilever pressure plate 6 by multiple bolts. The cantilever back plate 81 is fixedly connected to one side close to the cantilever pressure plate 6 with multiple clamping units, and the clamping unit includes a spring 82, and the other end of the spring 82 is fixedly connected with a pressure pin 83, and the pressure pin 83 is used to fix the PIN part 9 in the loading and fixing groove 4; it can be understood that the setting quantity of the above-mentioned springs 82 and pressure pins 83 should correspond to the fixing groove 4 and / or the fixing hole 2.

[0035] It should be noted that a space for arranging the spring 82 and the pressing pin 83 should be reserved in the cantilever pressing plate 6, and the interior of the cantilever pressing plate 6 may be hollow or have corresponding holes / grooves.

[0036] During actual use of the utility model, first, the buckle 7 is separated from the overlapping portion on the cantilever pressing plate 6 to open the cantilever pressing plate 6; then the PIN part 9 is placed in the fixing hole 2 and the fixing groove 4; after the PIN part 9 is placed, the cantilever pressing plate 6 is lowered, and the pressing pin 83 acts on the PIN part 9 to reliably fix it in the fixing groove 4, and the cantilever pressing plate 6 is fixed by the buckle 7 and the overlapping portion, thereby realizing batch fixation of the PIN parts 9.

[0037] In order to prevent the end of the pressure pin 83 from acting on the PIN part 9 and causing damage, in this embodiment, a flexible pad is further provided at the end of the pressure pin 83.
