Or gear rack ontology is screwed out, and the position of convex block is limited by caging bolt, prevent convex block from deviating from from gear rack ontology.
To achieve the above object, the invention proposes a kind of easily stubborn type gear racks, including gear rack ontology, caging bolt and turn
Bar, the outside of the gear rack ontology are equipped with external screw thread, and the first through hole being interconnected and the are equipped in gear rack ontology top
Two through-holes, the inner wall of second through-hole are equipped with internal screw thread, and the outside of the screw rod of the caging bolt is equipped with and the second through-hole
The external screw thread that matches of internal screw thread, be equipped with third through-hole in the caging bolt, the turn bar includes the body of rod and body of rod bottom
The convex block in portion.
Preferably, the section of the convex block is cross, the shape of the first through hole is matched with the shape of convex block.
Preferably, the diameter of second through-hole is greater than the width of first through hole, the width of the first through hole is greater than
The diameter of the body of rod.
Preferably, the caging bolt is spun in the second through-hole of gear rack ontology, the convex block of the turn bar passes through limit
The third through-hole of position bolt is inserted in the first through hole of gear rack ontology.
Preferably, the bottom of the gear rack ontology is equipped with guide part.
Preferably, being staggeredly equipped with several protrusions and groove on the outside of the screw head at the top of the caging bolt.
Preferably, the upper end of the body of rod is equipped with groove, adhere to rubber sleeve in the groove, the rubber sleeve it is outer
Side is uniformly provided with several tread plates.
Preferably, the body of rod and convex block are integrally formed.
Beneficial effects of the present invention: the present invention is by being inserted into criss-cross convex block into the second through-hole, thus not breaking
Using the precession of turn bar or gear rack ontology is screwed out under conditions of bad gear rack body surface screw thread, and is limited by caging bolt convex
The position of block prevents convex block from deviating from from gear rack ontology.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.

[specific embodiment]
Refering to fig. 1 to Fig. 7, a kind of easily stubborn type gear rack of the present invention, including gear rack ontology 1, caging bolt 2 and turn bar 3, institute
The outside for stating gear rack ontology 1 is equipped with external screw thread, is equipped with interconnected first through hole 11 and second in 1 top of gear rack ontology
Through-hole 12, the inner wall of second through-hole 12 are equipped with internal screw thread, and the outside of the screw rod 23 of the caging bolt 2 is equipped with and second
The external screw thread that the internal screw thread of through-hole 12 matches, the caging bolt 2 is interior to be equipped with third through-hole 22, and the turn bar 3 includes bar
The convex block 32 of 31 bottom of body 31 and the body of rod, the section of the convex block 32 are cross, the shape and convex block of the first through hole 11
32 shape matches, and the diameter of second through-hole 12 is greater than the width of first through hole 11, the width of the first through hole 11
Greater than the diameter of the body of rod 31, the caging bolt 2 is spun in the second through-hole 12 of gear rack ontology 1, the turn bar 3 it is convex
The third through-hole 22 that block 32 passes through caging bolt 2 is inserted in the first through hole 11 of gear rack ontology 1, the bottom of the gear rack ontology 1
Portion is equipped with guide part 13, is above staggeredly equipped with several protrusions and grooves, institute on the outside of the screw head 21 at the top of the caging bolt 2
