[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 3 The utility model provides a technical solution: a jig for drilling deep holes in plastics, comprising a clamping block 1, a positioning groove 2 being provided on the clamping block 1, a plastic product 3 being placed in the positioning groove 2, a movable adjustment block 4 being provided on the left side of the clamping block 1, the movable adjustment block 4 being connected to a locking screw 5, and the locking screw 5 being connected to the clamping block 1 through a thread.

[0017] A limiting plate 101 is fixed on the clamping block 1, and the limiting plate 101 contacts the plastic product 3 to achieve a limiting effect. The clamping block 1 is symmetrically provided with arc grooves 102 above and below, and the arc grooves 102 are connected to the positioning groove 2; the positioning groove 2 and the plastic product 3 are nested, and the depth of the positioning groove 2 is greater than the thickness of the plastic product 3; the movable adjustment block 4 is evenly spaced on the clamping block 1, and there is a one-to-one correspondence between the movable adjustment block 4 and the locking screw 5; a strip groove 401 is provided on the movable adjustment block 4, and the strip groove 401 and the locking screw 5 are slidingly connected, and the movable adjustment block 4 can be locked with the clamping block 1 by the locking screw 5; a pressing head 402 is also fixed on the movable adjustment block 4, and the pressing head 402 contacts the plastic product 3 to achieve a limiting effect, and a rubber protective pad is bonded to the contact surface of the pressing head 402 and the plastic product 3;
