A tie rod is connected, tie rod is arranged in the direction of fall side on first inclined-plane, and bolt connects with unification spring and the plug connections
It connects and is fixed together, which is equipped with mutually matched with the first inclined-plane of pin base towards one end of pin base
Second inclined-plane, the bolt and plug connections are fixed in the fixing sleeve.
Further, the plug connections are equipped with a pin hole, and the bolt is equipped with lockhole corresponding with the pin hole, should
Bolt and plug connections are fixed on by an axis pin in the fixing sleeve.
Further, the bolt is equipped with a gear wall, and the bolt connecting seat is equipped with a baffle, one end of the spring
It is resisted against on gear wall, the other end is held on baffle.
Further, the utility model bolt position limiting structure further includes a connector sleeve, the top of connector sleeve and the fixing sleeve
Secure fit together, is equipped with a partition board in the connector sleeve, the top of partition board forms upper chamber, and the lower section of partition board has for adjusting
The lower chambers of pole setting, the pin base are arranged on partition board, and partition board is equipped with the location hole passed through for the bolt.
With the above structure, the utility model bolt position limiting structure be by the way that the first inclined-plane is arranged on pin base,
Second inclined-plane is set on plug connections, by the mutual lifting for realizing bolt on two inclined-planes so that bolt with it is fixed
The limit or separation in position hole, it is very easy to use.When the utility model is used, the fixing sleeve is fixed, by one end of bolt
It is caught under the action of the spring to the elongated slot of protrusion pin base, at this time the of the first inclined-plane of pin base and bolt connecting seat
Two inclined-planes are combined together, and bolt is located at the one end of elongated slot far from tie rod, when releasing the limit of bolt and elongated slot, are pulled and are drawn
Item, make pin base toward tie rod direction move, pin base move when, the first inclined-plane can squeeze plug connections second tiltedly
Face, so that the second inclined-plane is driven bolt, up mobile and compressed spring relieves slotting until being moved in elongated slot on the bottom end of bolt
The limit of pin.When unclamping tie rod, bolt has a downward power always under the action of the spring, is limited again convenient for bolt
Position.

Specific implementation mode
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
As shown in Figure 1 to Figure 4, the utility model discloses a kind of bolt position limiting structure comprising a pin base 1, a bolt
Connector 2, a bolt 3, a fixing sleeve 4.As shown in each figures, the utility model can also further comprise a connecting seat 5.
The pin base 1 is equipped with a short slot 11, and the bottom of short slot 11 is equipped with an elongated slot 12 passed through for bolt 3, this is inserted
Sell pedestal 1 and be equipped with the first inclined-plane 13 in the side of short slot 11, connect a tie rod 6 on the pin base 1, the setting of tie rod 6 this
The direction of fall side on one inclined-plane 13.
The plug connections 2 connect to the fixation bolt 3, the bolt 3 with unification spring 7 and the plug connections 2
It connects and is fixed together, as shown in Figure 1, the plug connections 2 are equipped with a pin hole 21, the bolt 3 is equipped with and the pin hole 3
Corresponding lockhole 31 is additionally provided with the gear wall 32 of 7 one end of spring described in a backstop, one end of bolt 3 and the bolt bottom on bolt 3
