Disclosure of Invention
The utility model aims to overcome the not enough of prior art, the problem of main solution can carry out inseparable, firm centre gripping to the part for providing a spring clamp material instrument, can prevent that the condition that drops or the centre gripping is fastened inadequately that appears in the clamping process from appearing.
The purpose of the utility model is realized like this: the clamping cavity is formed in the chuck, an inserting hole for inserting an external rod piece is formed in the chuck, offset seams are formed in the side wall of the clamping cavity, a sliding groove is further formed in the side wall of the clamping head, and a clamping hoop for fastening is connected in the sliding groove in a sliding mode.
Furthermore, one side still is equipped with the draw-in groove in the spout, the centre gripping hoop inside wall is connected with the fixture block with draw-in groove looks adaptation.
Still further, the outer side wall of the clamping hoop is provided with a plurality of anti-skidding protrusions.
Furthermore, the diameter of the opening at the lower end of the clamping cavity is larger than the inner diameter of the clamping cavity, and the diameter of the upper end of the clamping cavity is smaller than the inner diameter of the clamping cavity.
Furthermore, a threaded hole is formed in the upper end of the chuck.
The technical effects of the utility model: when using this device to carry out the centre gripping to the part, aim at the part that needs the centre gripping with the lower extreme of chuck, then cup joint it in the centre gripping intracavity, the biasing seam makes the centre gripping arc board of the formation symmetry setting in centre gripping chamber carry out the centre gripping to the part, the centre gripping hoop that slides after the centre gripping and be located the chuck upper end outside moves to the opposite side, it fastens and protects the position department of chuck lower extreme clamping part in the draw-in groove to move suitable position department rotation centre gripping hoop messenger its inner wall's fixture block card, the centre gripping stability of improvement device and its life.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The present invention will be described in detail with reference to the accompanying drawings.
The utility model provides a spring clamp material instrument, includes chuck 1, grip chamber 2 has been seted up in the chuck 1, set up on the chuck 1 and supply outside member male jack 3, set up offset seam 4 on the 2 lateral walls in grip chamber, still be equipped with spout 5 on the 1 lateral wall of holding head, sliding connection has the centre gripping hoop 6 of fastening usefulness in the spout 5.
As shown in fig. 1-4, when clamping is performed to the invisible part during use, the lower end of the chuck 1 is aligned to the part to be clamped, and then the part is sleeved into the clamping cavity 2, the clamping cavity 2 forms two groups of symmetrically arranged clamping arc plates by the arrangement of the offset seam 4, the part can be clamped by using the plastic deformation of the clamping arc plates, the clamping hoop 6 positioned at the upper end of the chuck 1 slides after clamping, and the clamping hoop is moved to the other end to fasten the clamped part again, so that the part can be prevented from falling off on the one hand, and on the other hand, the chuck 1 can be prevented from being irreversibly deformed under the clamping in long-time use, and the situation that the clamping is not fastened stably enough or can not be used again in the subsequent use is caused.
According to the utility model discloses an embodiment, one side still is equipped with draw-in groove 7 in the spout 5, 6 inside walls of centre gripping hoop are connected with the fixture block 8 with draw-in groove 7 looks adaptation. The centre gripping hoop 6 is when sliding, spout 5 can be spacing to it, convenient operation on the one hand, on the other hand can prevent the skew of centre gripping hoop 6, move centre gripping hoop 6 to suitable draw-in groove 7 position department as required at the in-process of in-service use, then rotate centre gripping hoop 6 and make in fixture block 8 can the joint draw-in groove 7, realize the spacing of centre gripping hoop 6, the setting of a plurality of draw-in grooves 7 can adapt to the part of various specifications more, when 2 clamping components in centre gripping chamber, further fastening is carried out to centre gripping hoop 6.
According to an embodiment of the present invention, the outer side wall of the clamping hoop 6 is provided with a plurality of anti-slip protrusions 9. The anti-slip protrusions 9 can facilitate the operation and rotation of an operator in the operation process, so that the position of the clamping hoop 6 can be adjusted.
