Come, extraneous impurity is not easily accessible, and impurity is not had will operate hole plug, when needing operation bolt to rotate, by operation instrument
Block is contradicted, and applies active force, spring stress compression so that block is entered in putting hole, can pass through operation instrument
Realize the rotation of bolt.
The utility model is further arranged to：Sliding block, the head and the spiral shell are provided with the side wall of the block
The slideway slid for the sliding block is provided with bar.
By using above-mentioned technical proposal, the combination of sliding block and slideway can realize the position restriction to block, and block exists
Stress can keep stable glide direction during being moved, be difficult to be stuck.
The utility model is further arranged to：The slideway to distance of the head away from described screw rod one end is equal to institute
Sliding block is stated to distance of the block away from described screw rod one end.
By using above-mentioned technical proposal, distance of the slideway to head away from screw rod one end is equal to sliding block to block away from spiral shell
The distance of bar one end so that under the action of the spring, the end face that can be retained stop when sliding block slides onto slideway top and head
End face it is concordant, realize good sealing process, and block will not protrude from head, will not take the space in the external world.
The utility model is further arranged to：Include in the screw rod and set positioned at the slideway away from described head one end
The supporting part put.
By using above-mentioned technical proposal, supporting part is set in screw rod, the position to sliding block can be realized by supporting part
Put restriction, so that the moving range of limit stop, the operation instrument made is entered can stably be supported in manipulation hole, be easy into
Row operation.
The utility model is further arranged to：Limited post is provided with the putting hole, one end of the spring is set in
On the limited post.
By using above-mentioned technical proposal, limited post is provided with putting hole, one end of spring is set on limited post
The restriction of position is realized, spring is not susceptible to position skew, improves the stability supported to block.
The utility model is further arranged to：Connecting pole is provided with the block, one end of the spring is set in institute
State on connecting pole.
By using above-mentioned technical proposal, set connecting pole to be combined with one end of spring on block, realize to spring
Position restriction, is not susceptible to position skew, so as to improve support effect of the spring to block between spring and block.
In summary, the utility model has the advantages that：It is provided with head and screw rod and handle hole UNICOM
Putting hole, and spring and block are set in putting hole, block can be supported under the action of the spring, so that will behaviour
It is closed as hole, is difficult to be blocked by impurity.Sliding block on the wall of block side is combined with slideway, and lifting block is in moving process
Stability, is difficult to be stuck, and sliding scope of the sliding block in slideway be defined so that block carry out sealing process when, energy
It is enough concordant with the end face on head, when operation instrument is inserted into handle hole, stable support can be carried out by baffle plate.
