The utility model aims at providing a simple structure, easy to assemble, the reliable forked tail slot type locking device of locking.
The utility model discloses a solve through following technical scheme: the device includes dovetail main part and dovetail seat, is equipped with locking mechanism wherein in the dovetail seat, and locking mechanism mainly comprises latch segment slide, activity latch segment, the latch segment slide is arranged in to the activity latch segment, be equipped with spring groove and straight line groove on the latch segment, countersunk screw passes straight line groove and fixes whole locking mechanism in the dovetail seat, spring groove head is equipped with the screw, and the spring one end is being connected through holding screw top, and the countersunk screw is being held against to the spring other end, latch segment slide head is equipped with the through-hole that corresponds with the spring groove, and holding screw is in simultaneously and is active state in this through-hole, latch segment upper portion is equipped with the inclined plane, dovetail seat upper portion is equipped with the screw, corresponds the cooperation through locking screw and latch segment upper portion inclined plane.
Furthermore, the lower end of the locking screw is circular.
Furthermore, the tail part of the locking block is an inclined plane which is parallel to a dovetail inclined plane of the dovetail seat.
Further, the width of the straight groove is larger than the diameter of the countersunk head screw.
The utility model has the advantages that:
1. the utility model discloses a locking screw screws, locking screw sinks, and circular head is near the latch segment inclined plane to promote the latch segment removal, the latch segment afterbody is along with removing, and the reliability of forked tail locking device locking has been improved to the part of treating in the dovetail of chucking.
2. The utility model discloses the advantage is in placing the spring inside the latch segment, and the operation after the locking screw of unscrewing reduces the latch segment to the position of not working hour, has improved forked tail locking device's practicality.
3. The utility model discloses the small and exquisite compactness of forked tail locking device overall structure, latch segment afterbody processing requirement is low, has the advantage of the manufacturing of being convenient for, can extensively be used for all kinds of devices that need the forked tail locking, improves forked tail locking device's popularity.

Detailed Description
The invention will be further explained with reference to the drawings of the embodiments.
As shown in the figure, the device comprises a dovetail groove main body 1 and a dovetail seat 2, wherein a locking mechanism is arranged in the dovetail seat 2, the locking mechanism mainly comprises a locking block sliding seat 3 and a movable locking block 4, the movable locking block 4 is arranged in the locking block sliding seat 3, the locking block 4 is provided with a spring groove 5 and a straight groove 6, a countersunk screw 7 passes through the straight groove 6 to fix the whole locking mechanism in the dovetail seat 2, the head of the spring groove 5 is provided with a screw hole, through the clamping screw 8 supporting one end of the spring 9 and the counter screw 7 supporting the other end of the spring 9, the head of the locking block sliding seat 3 is provided with a through hole 11 corresponding to the spring groove 5, the clamping screw 8 is in a movable state in the through hole 11, the upper portion of the locking block 4 is provided with an inclined surface 12, the upper portion of the dovetail seat 2 is provided with a screw hole 10, and the locking screw 14 is correspondingly matched with the inclined surface 12 on the upper portion of the locking block 4. The lower end of the locking screw 14 is round; the tail part of the locking block 4 is an inclined surface 16 which is parallel to a dovetail inclined surface of the dovetail seat 2; the width of the straight groove 6 is larger than the diameter of the countersunk head screw 7.
When the dovetail groove locking device is operated, firstly, a part to be machined is arranged in the dovetail groove, the locking screw 14 sinks, the circular head part abuts against the inclined surface 12 of the locking block, the locking block 4 is pushed to move, the tail part of the locking block 4 moves along with the movement of the locking block to clamp the part to be machined arranged in the dovetail groove, and the dovetail groove locking device achieves the purpose of locking, at the moment, one end of the spring 9 abuts against the fixed countersunk screw 7, when the locking block 4 moves in the dovetail groove to clamp the part to be machined arranged in the dovetail groove, the fastening screw 8 fixed on the locking block 4 moves, and the spring 9 is compressed, so that the spring 9 is in a compressed state; after the locking screw 14 is unscrewed, the locking block 4 is restored to the non-operating state under the action of the spring.
To sum up, this forked tail slot type locking device relies on countersunk screw 7 to install on dovetail seat 2, and forked tail locking device dismantles and simple to operate is swift, effectively improves forked tail slot type locking device's convenience, reliability, practicality. The dovetail groove type locking device is small and compact in overall structure, low in requirement for machining the tail part of the locking block 4, convenient to machine and manufacture, capable of being widely applied to various devices needing dovetail locking, and capable of improving the universality of the dovetail locking device.
