Fig. 1 is overall structure schematic diagram of the present utility model;

Fig. 2 is pull-type handle side structural representation of the present utility model.

Number in the figure explanation: 1, lower platen, 2, top board, 3, stage clip, 4, torsion spring, 5, large rivet one, 6, pull-type handle, 7, support tooth, 8, little rivet, 9, triangle turnup structure, 10, screw dodges groove, 11, the handle that tilts, 12, large rivet two, 13, dodge groove two, 14, large rivet three.

The specific embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.

Shown in Fig. 1 and Fig. 2, pull-type bolt device, comprise lower platen 1, lower platen 1 both sides, below are provided with rotatable support tooth 7, support tooth 7 middle parts are fixing by little rivet 8, and rotatable around little rivet, and support tooth 7 inside top are also conflicted and are connected with torsion spring 4, make two support tooth 7 tops have all the time an outside active force, wherein torsion spring 4 is set on the large rivet 1 being fixed on lower platen 1;

Lower platen 1 inside is also connected with pull-type handle 6 by stage clip 3, described stage clip 3 is S type spring, S type spring is flat shape, not high to the space requirement between lower platen 1 and pull-type handle 6, can well be arranged on inside, reduce small product size, and stage clip 3 one end are connected with pull-type handle 6, the other end is fixedly connected with the large rivet 2 12 being fixed on lower platen 1, can give 6 one downward continuous action power of pull-type handle like this;

Pull-type handle 6 bottoms are positioned at lower platen 1 one sides and are vertically installed with triangle turnup structure 9, conflict and be connected with the support tooth 7 of described lower platen 1 both sides, below respectively in triangle turnup structure 9 inclined-planes, both sides, when pull-type handle 6 pulls, triangle turnup structure 9 rises thereupon, support tooth 7 bottoms are along with its inclined-plane glides, obtain an outside active force, and pull-type handle 6 tops are provided with the inclination handle 11 of 30 °, be convenient to user and pull pull-type handle 6, its angle is difficult for excessive, for example, while becoming vertical, will certainly form hook formation, easily be hooked to miscellaneous part, wherein on handle 11 surfaces that tilt, be provided with anti-slip tank, in order to avoid cause slippage when operation,

On lower platen 1, be also covered with top board 2, top board 2 tops are connected with large rivet 2 12, middle part is connected with large rivet 1, bottom is connected with large rivet 3 14, the parts that arrange on lower platen 1 are well covered between, wherein on pull-type handle 6, in order to dodge large rivet 2 12 and large rivet 1, to turn round and look to arrange, dodge groove 2 13 and dodge groove 1, leave space surplus, also define the motion bound of pull-type handle 6.

The operation principle of the present embodiment is as follows:

Bolt device described in the utility model can effectively coordinate existing socket to use, during original state, pull-type handle 6 is by the downward active force of stage clip 3, bottom is close to lower platen 1 lower bottom part all the time, support tooth 7 tops are by the outside tension force of torsion spring 4, two ends stretch out in lower platen 1 both sides, and support tooth 7 bottoms are close on the inclined-plane of triangle turnup structure 9.

During use, directly bolt device described in the utility model is touched and insert socket, socket latch edge is touched at support tooth 7 tops, obtains a power to the inside, and the rear retraction of extruding torsion spring 4 is downward along socket latch wall, behind in-position, looses one's grip.

Finish using in the time of need to extracting, pull out

handle

11,6, pull-type handle moves upward, the downward active force of 3 pairs of pull-type handles 6 of stage clip becomes large, in this simultaneously, motion due to pull-type handle 6, support tooth 7 bottoms on 9 liang of inclined-planes of its triangle turnup structure rise on inclined-plane and position on inclined-plane declines, making to support tooth 7 bottoms moves laterally, support tooth 7 is by the setting of little rivet 8, top is motion to the inside, and bounces back in lower platen 1 to 4 one active forces of torsion spring, so just can smoothly latch be extracted.

Extract after latch, unclamp handle 11, the active force of 3 pairs of pull-type handles 6 of stage clip is discharged, pull-type handle 6 is moved downward, after moving downward, its triangle turnup structure 9 declines thereupon, and inwardly moving with inclined-plane by the outside tension force of torsion spring 4 in support tooth 7 bottoms, is back to initial position.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
