Problems solved by technology
[0003] For a long time, the structure of bolts and nuts has been the choice of most users due to its convenient structure, low cost and good effect. However, the process of installing or disassembling the bolts and nuts is relatively long; in addition, Bolts are screwed together with hexagonal nuts using threaded rods. Due to the insufficient pressure of the nuts against the locked object, the locking structure may become loose or even fall off from time to time.

Embodiment Construction
[0023] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0024] Such as figure 1 with figure 2 As shown, the present invention is a fast slot locking device, which mainly includes a talons 2 , a talons ejector rod 5 , a main cavity 1 and a slot 9 matching with the talons 2 .
[0025] In the specific structure, refer to figure 1 , figure 2 with image 3 , The talons 2 are composed of two talons blocks, and are hinged to the head end of the adapter 4 through the talons shaft 3 at the same time. The outer contour of the talons 2 in contact with the main cavity 1 is a smooth curve, which is convenient for the expansion and contraction of the talons.
[0026] refer to figure 1 , figure 2 , Figure 4 with Figure 5 , the front end of the adapter 4 is provided with a hinge hole, which is hinged with the claw shaft 3, and has a circular groove at the end. The axial direction of the clamp ejector r...

The invention discloses a quick locking device with a clamping groove. The quick locking device with the clamping groove comprises a claw plier and the clamping groove matched with the claw plier, theclaw plier is hinged to the head end of an adapter through a claw plier shaft, the tail end of the adapter is connected with the head end of a claw plier ejector rod, a rotating handle is installed at the tail end of the claw plier ejector rod, the claw plier ejector rod and the claw plier are both located in a main cavity body, a penetrating through hole for the claw plier to stretch out and retract in is formed in the side wall of the front portion of the main cavity body, an internal thread is arranged on the inner side wall of the front portion of the main cavity body, and an external thread matched with the internal thread of the main cavity body is arranged on the outer wall of the front portion of the claw plier ejector rod. Through the threaded fit of the claw plier ejector rod and the main cavity body, the claw plier is controlled to extend out of and retract into the penetrating through hole by rotating the rotating handle, and therefore the purpose of locking and clamping is achieved. The quick locking device with the clamping groove is simple in clamping, convenient to machine and convenient to realize quick mounting and dismounting.
Description
technical field [0001] The invention belongs to the technical field of fixture design, and in particular relates to a fast card slot locking device. Background technique [0002] The locking device is generally used to detachably lock two or more parts temporarily, and is generally used in the processing and assembly of workpieces and other scenarios. At present, the most used and convenient locking device is generally a combination of bolts and nuts. structure. [0003] For a long time, the structure of bolts and nuts has been the choice of most users due to its convenient structure, low cost and good effect. However, the process of installing or disassembling the bolts and nuts is relatively long; in addition, Bolts are threaded rods and hexagonal nuts are screwed together. Due to the insufficient pressure of the nut against the locking object, the locking structure may become loose or even fall off from time to time. Contents of the invention [0004] In order to over...
