The convex block of body bottom.
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.
The utility model has the beneficial effects that the utility model is by being inserted into criss-cross convex block into the second through-hole, from
And using the precession of turn bar or gear rack ontology is screwed out under conditions of not destroying gear rack body surface screw thread, and pass through limit spiral shell
Bolt limits the position of convex block, prevents convex block from deviating from from gear rack ontology.
The feature and advantage of the utility model 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 utility model, including gear rack ontology 1, caging bolt 2 and turn bar
3, the outside of the gear rack ontology 1 is equipped with external screw thread, is equipped with interconnected 11 He of first through hole in 1 top of gear rack ontology
Second through-hole 12, the inner wall of second through-hole 12 are equipped with internal screw thread, the outside of the screw rod 23 of the caging bolt 2 be equipped with
The external screw thread that the internal screw thread of second through-hole 12 matches, the caging bolt 2 is interior to be equipped with third through-hole 22, and the turn bar 3 wraps
Include the convex block 32 of 31 bottom of the body of rod 31 and the body of rod, the section of the convex block 32 is cross, the shape of the first through hole 11 with
The shape of convex block 32 matches, and the diameter of second through-hole 12 is greater than the width of first through hole 11, the first through hole 11
Width is greater than the diameter of the body of rod 31, and the caging bolt 2 is spun in the second through-hole 12 of gear rack ontology 1, the turn bar 3
Convex block 32 pass through caging bolt 2 third through-hole 22 be inserted in the first through hole 11 of gear rack ontology 1, the gear rack ontology 1
Bottom be equipped with guide part 13, upper several protrusions and recessed of being staggeredly equipped on the outside of the screw head 21 at the top of the caging bolt 2
