Abstract
The invention relates to a simple G-shaped clamp. The simple G-shaped clamp comprises a clamp body, a movable head, a screw and a handle. The clamp body comprises a mounting portion and a clamping portion, the mounting portion is provided with a through hole, the screw penentrates the through hole, the movable head is arranged at one end of the screw right facing the clamping portion, the screw is movably connected with the other end of the screw through a pin shaft, the inner wall of the through hole is provided with an arc-shaped groove, an arc-shaped block with a thread is identical with the groove in shape and arranged in the same, the arc-shaped block is connected with the groove through a spring, the bottom of the groove is provided with a threaded hole communicated with the through hole, a stud is arranged in the threaded hole and penetrates the threaded hole and the spring to contact with the arc-shaped block, and the tail end of the stud is provided with a knob. By adopting the technical scheme, the stud is screwed by rotating the knob, and the thread of the arc-shaped block is meshed with the thread of the screw, so that the simple G-shaped clamp is locked or otherwise is unlocked. The simple G-shaped clamp is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of fixture, be specifically related to a kind of simple and easy G word folder.
Background technology
G word folder is a kind of hardware & tools that workpiece, module etc. for clamping various shape play the G font of fixation.Existing G word folder comprises clamp and screw rod, screw rod is threaded with the internal thread hole of clamp installation portion, during holding workpiece, by continuous rotary screw, thus by piece-holder between the segmented head and the clamping part of clamp of screw rod, such clamping efficiency comparison is low.In addition, when screw rod and internal thread hole excesssive gap, screw thread is easily impaired, and the service life of G word folder can reduce greatly.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of simple and easy G word folder.
Realize technical scheme of the present invention as follows:
A kind of simple and easy G word folder, comprise clamp, segmented head, screw rod, handle, described clamp comprises installation portion and clamping part, installation portion has through hole, described screw rod places in through-holes, described segmented head be arranged on screw rod just to one end of clamping part, described handle is flexibly connected by bearing pin with the other end of screw rod, described through-hole wall is provided with arc groove, the arc block identical with groove shapes is provided with in groove, arc block surface is provided with the screw thread matched with screw flight, in groove, and there is the stroke space being convenient to the activity of arc block between arc block and screw mandrel screw rod, arc block is connected by spring with between groove, bottom portion of groove is provided with the screwed hole be communicated with through hole, stud is provided with in screwed hole, stud is placed through screwed hole, in spring, and contact with arc block, the end of stud is provided with knob.
Further, described screwed hole is arranged on bottom portion of groove central authorities.
Have employed above-mentioned scheme, make screwing up stud by turning knob, and then make arc block screw thread want to engage with screw flight, thus realize the locking of simple and easy G word folder; Otherwise, then unlock.Structure of the present invention is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is installation portion structure schematic diagram in Fig. 1;
Fig. 3 be in Fig. 2 A-A to structural representation;
In figure, 1 is clamp, and 2 is screw rod, and 3 is handle, and 4 is segmented head, and 5 is clamping part, and 6 is installation portion, and 7 is arc groove, and 8 is arc block, and 9 is spring, and 10 is stud, and 11 is knob, and 12 is screwed hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, 2, 3, a kind of simple and easy G word folder, comprise clamp 1, segmented head 4, screw rod 2, handle 3, described clamp comprises installation portion 6 and clamping part 5, installation portion has through hole, described screw rod places in through-holes, described segmented head be arranged on screw rod just to one end of clamping part, described handle is flexibly connected by bearing pin with the other end of screw rod, described through-hole wall is provided with arc groove 7, the arc block 8 identical with groove shapes is provided with in groove, arc block surface is provided with the screw thread matched with screw flight, in groove, and there is the stroke space being convenient to the activity of arc block between arc block and screw mandrel screw rod, arc block is connected by spring 9 with between groove, bottom portion of groove is provided with the screwed hole 12 be communicated with through hole, stud 10 is provided with in screwed hole, stud is placed through screwed hole, in spring, and contact with arc block, the end of stud is provided with knob 11.
When not using, under the action of the spring, arc block does not contact with screw rod; During use, workpiece is placed between clamping part and segmented head, makes stud go deep in screwed hole by screwing knob, engaging with screw flight under the promotion of the stud of arc block, thus realize locking.Otherwise arc block, realizes unlocking away from screw rod in the effect of spring.
The setting of handle, is conducive to operator and holds.The present invention only has in use, to be engaged and realizes locking, reduce screw thread loss percentage, improve the service life of G word folder by arc block with screw flight.
Further, described screwed hole is arranged on bottom portion of groove central authorities, and stud is placed through in screwed hole, spring, can guarantee that arc block contacts with the stable of screw rod.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
