Embodiment

The utility model is further elaborated below in conjunction with the accompanying drawings：

With reference to shown in Fig. 1 and Fig. 2, tool includes：Pallet 1, reinforcing plate 2, multiple fixture blocks 3 and multiple shell fragments 4.Reinforcing plate 2 It is bonded with pallet 1.Pallet 1 has multiple fixing holes 11, multiple paster holes 12, multiple first grooves 13, multiple second grooves 14 With multiple 3rd grooves 15.Pallet 1 is run through in fixing hole 11 and paster hole 12, and the first groove 13 is located at the front of pallet 1, and second is recessed The groove 15 of groove 14 and the 3rd is located at the back side of pallet 1.

As shown in figure 3, the first groove 13 is in " scholar " font, each first groove 13 has a cannelure 131, one the One transverse groove 132 and second transverse groove 133.First transverse groove 132 passes through the middle part of cannelure 131, the second transverse groove 133 Through one end of cannelure 131.

As shown in figure 4, pallet 1 also has multiple first through hole 101 and multiple second through holes 102.Cannelure 131 it is another End is connected by first through hole 101 with the second groove 14, and the both ends of the first transverse groove 132 pass through the second through hole 102 and two respectively Individual 3rd groove 15 connects.

With reference to shown in Fig. 3, Fig. 4 and Fig. 5, there is back-off 31 and boss 32 on fixture block 3, back-off 31 is located at one end of fixture block 3, Boss 32 is located at the middle part of fixture block 3.Fixture block 3 is located in cannelure 131, and the other end of fixture block 3 is extended to by first through hole 101 In second groove 14.

Shell fragment 4 includes：One elastic ring 41 and two elastic support arms 42.Elastic ring 41 is embedded in back-off 31, elastic support arm 42 are extended in the 3rd groove 15 from elastic ring 41 by the second through hole 102, and are abutted with the inwall of the 3rd groove 15.
