As shown in fig. 7, after the angle of the adjusting pipe is adjusted to a set angle, the locking nut is screwed to move toward the connecting sleeve, the locking nut is separated from the outer sleeve until the locking nut is locked on the outer wall of the connecting sleeve, so that the screw and the eccentric wheel are locked and fixed on the connecting sleeve, and at this time, the rocking handle cannot drive the screw to rotate. Although the angle of the chuck can be adjusted according to the requirement, the requirement of actual clamping can be facilitated, and the adaptability is improved; but also brings the problems that in the operation process, the angle of the adjusting pipe and the chuck is changed due to the fact that an operator touches or collides the rocking handle carelessly and the driving screw rod rotates, so that the normal operation of the operation is influenced, and even the operation fails; in order to solve the problem, the scheme is provided with a locking and anti-misoperation rotating mechanism, and particularly, after the angle of the adjusting pipe is adjusted to a set angle, the adjusting pipe is locked on the outer wall of the connecting sleeve through a locking nut, so that the angle of the adjusting pipe is locked; more importantly, at this moment, lock nut and outer axle sleeve separation, outer axle sleeve can rotate for outer polished rod, the rocking handle can not drive screw rotate, so, even appear operating personnel touching or colliding the rocking handle carelessly in the operation process, can not drive screw rotate yet (although lock nut locks on adapter sleeve's outer wall, the nut can't be toward adapter sleeve internal rotation, but still can be toward adapter sleeve external rotation), thereby can avoid in the operation process, because of operating personnel touching or colliding the rocking handle carelessly, and drive screw rotates, make the angle of regulating tube and chuck change, and influence the operation and normally go on, lead to the problem of operation failure even.
The outer wall of the connecting sleeve where the threaded hole is located is provided with a boss, the end face of the boss is perpendicular to the axis of the screw, and the threaded hole penetrates through the boss. When the locking nut is locked on the outer wall of the connecting sleeve, the end face of the locking nut is tightly pressed on the end face of the boss, so that the locking nut is locked on the outer wall of the connecting sleeve.
Further, as shown in fig. 7, the detachable clip applier further comprises a mis-operation prevention locking mechanism 7. The anti-misoperation locking mechanism comprises a return spring 7.3, an annular limiting groove 7.1 arranged on the push rod, a first guide hole and a second guide hole which are arranged on the side wall of the connecting sleeve, a sliding guide rod 7.2 arranged in the first guide hole in a sliding manner, a sliding limiting rod 7.4 arranged in the second guide hole in a sliding manner, and a connecting piece 7.5 for connecting the sliding guide rod and the sliding limiting rod. The axes of the screw rod, the sliding guide rod and the sliding limiting rod are parallel. The sliding guide rod and the sliding limiting rod are positioned on the same side of the locking nut. The first end of the sliding guide rod is abutted against the end face of the locking nut under the action of the return spring, and the second end of the sliding guide rod, the sliding limiting rod and the connecting piece are located on the same side of the push rod. The sliding limiting rod and the locking nut are positioned on two sides of the push rod. In this embodiment, the reset spring is a tension spring, the tension spring and the connecting piece are located on the same side of the connecting sleeve, one end of the tension spring is connected with the connecting piece, and the other end of the tension spring is connected with the outer wall of the connecting sleeve.

When the outer shaft sleeve is locked and fixed on the end stop block by the locking nut, the sliding limiting rod is inserted into the annular limiting groove under the action of the reset spring.
In actual operation, irregular operation may exist, after the angle of the chuck is adjusted to a set angle, the operation forgets to lock the locking nut on the outer wall of the connecting sleeve (the locking nut keeps the outer sleeve locked and fixed on the end stop block), so that the angle of the chuck cannot be locked in the operation process, and the problem that the angle of the adjusting pipe and the chuck is changed due to the fact that an operator touches or collides the rocking handle carelessly and the driving screw rotates in the operation process, so that the normal operation is influenced, and even the operation fails cannot be solved; to this end, the present solution provides a locking mechanism against incorrect operation, to solve this problem, in particular,
in actual operation, if the operation is carried out according to the specification, after the angle of the chuck is adjusted to a set angle, the locking nut is locked on the outer wall of the connecting sleeve, and at the moment, the sliding limiting rod is positioned on the outer side of the annular limiting groove, so that the angle of the adjusting pipe can be locked, and the situation that an operator touches or collides the rocking handle carelessly to drive the screw rod to rotate in the operation process can be avoided; the sliding limiting rod is positioned on the outer side of the annular limiting groove, so that the clamp handle cannot be influenced to drive the push rod to move along the outer sleeve to drive the clamp head to open and close, and the clamping function of the clamp head is realized;
if the operation is not standard, after the angle of the chuck is adjusted to a set angle, the operation forgets to lock the locking nut on the outer wall of the connecting sleeve, at the moment, the sliding limiting rod is inserted into the annular limiting groove under the action of the reset spring, so that the position of the push rod is locked by the sliding limiting rod, an operator cannot drive the push rod to move along the outer sleeve through the clamp handle, cannot drive the chuck to open and close, and cannot work the clamp applying tool; therefore, an operator is reminded that the operation is not standard and the locking nut is not locked on the outer wall of the connecting sleeve, so that the operator can lock the locking nut on the outer wall of the connecting sleeve according to the standard operation; thereby effectively solve probably to have the operation of irregularity in actual operation, after the chuck angle modulation to the set angle, the operation has forgotten the problem of locking lock nut on adapter sleeve's outer wall.
In this embodiment, the connector is located outside the connection sleeve. The first end of the sliding guide rod is provided with a hemispherical bulge, and the hemispherical bulge is propped against the end face of the locking nut under the action of the reset spring.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
