Detailed Description

In order to facilitate understanding of the invention, the invention will be described more fully hereinafter with reference to the accompanying drawings, in which several embodiments of the invention are shown, but which can be embodied in many different forms and are not limited to the embodiments described herein, but which are provided so as to render the disclosure of the invention more thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present; when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present; the terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; as used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Example 1

Referring to fig. 1-2, the locking device of this embodiment includes a handle head 110 and a slot 130 movably connected to the handle head 110, a handle head through hole 111 is penetratingly disposed in the handle head 110, a handle 120 is penetratingly disposed in the handle head through hole 111, an opening 140 is disposed on a side of the slot 130 away from the handle head 110, and a shape of the opening 140 is adapted to a shape of a component to be locked. The slot 130 is circumferentially provided with a plurality of through slot through holes 131. Two opposite clamping ends 132 are disposed at two sides of the opening 140, and the clamping ends 132 include two parallel sections 133 and an arc-shaped section 134, and two parallel sections 133 are disposed at two ends of the arc-shaped section 134.

The locking device of this embodiment drives handle head 110 and draw-in groove 130 through handle 120 and carries out synchronous rotation and lock the work piece, because handle head 110 and draw-in groove 130 swing joint, when using in the less region in space, can lift handle head 110 off, directly cooperate with handle 120 through draw-in groove through-hole 131 in draw-in groove 130 and carry out centre gripping locking to the work piece that needs centre gripping locking, can satisfy the demand of locking the clamp in narrow and small space, the practicality strengthens greatly.
