the hydraulic cylinder is arranged in the cavity of the guide main body, and the head of the hydraulic rod is connected with the side wall of the guide main body;

the fixing base, fixing base fixed mounting is close to the one end of first hook plate in the slide rail main part, the afterbody fixed connection of pneumatic cylinder is on the fixing base, still be connected with the joint on the fixing base, thereby connect and provide drive power to the pneumatic cylinder fuel feeding through connecting oil pipe and oil pump. Further one end fixed mounting of slide rail main part has the bounding wall, the bounding wall is the type of falling U and wraps up the slide rail main part, second hook plate fixed mounting is in the bounding wall upper end.

Furthermore, a first clamping groove is formed in the first hook plate, a second clamping groove is formed in the second hook plate, and the first clamping groove and the second clamping groove are arranged oppositely.

Further the direction main part is through seting up connecting hole and hydraulic stem bolted connection on the lateral wall.

The first clamping groove and the second clamping groove are circular, and the centers of circles of the first clamping groove and the second clamping groove are on the same straight line.

The utility model has the advantages that:

compared with the prior art the utility model discloses a characteristics lie in providing a simple structure's tightener to through seting up the draw-in groove on the hook plate, utilize the draw-in groove to connect the track round pin, thereby make two hook plates tighten up relatively through the oil pump fuel feeding and make the track round pin drive the track plate tighten up, tighten up the effect better, and labour saving and time saving.

Detailed Description

It should be noted that the terms "first" and "second" in the present invention are not intended to limit the number or the installation sequence, but only to distinguish the names of the components, and the terms "left, right, up and down" in the claims and the description are used to better describe the drawings, and when the position of the retractor is changed in practice, the terms "left, right, up and down" should be changed accordingly.

Referring to the drawings specifically, an oil pump 1 is connected with an oil pipe 12, the other end of the oil pipe 12 is connected with a hydraulic cylinder 8 through a joint 2 on a connecting fixing seat 7, the hydraulic cylinder 8 is installed in a cavity 6.5 of a guide main body 6.3, the front end of a hydraulic rod 9 forms a bolt connection through a connecting hole 6.2 on a side wall 10 of the guide main body 6.3, so that the hydraulic rod 9 can push the guide main body 6.3 to move by supplying oil through the oil pump 1, a first hook plate 6.1 is installed at one open end of the cavity 6.5 on the guide main body 6.3, the guide main body 6.3 and the first hook plate 6.1 form a guide assembly 6, the guide main body 6.3 on the guide assembly 6 is penetrated in a penetrating cavity 5.5 of a rail main body 5.3 on the rail assembly 5, the guide main body 6.3 can move left and right in the penetrating cavity 5.5, a chute 11 for the first hook plate 6.1 to move is formed on the upper end face of the rail main body 5.3, one, the enclosing plate 5.2 is in an inverted U shape and wraps the slide rail main body 5.3, the enclosing plate 5.2 is fixedly connected with a second hook plate 5.1, the other end of the slide rail main body 5.3 is used for the guide main body 6.3 to penetrate, the side wall 10 of the guide main body 6.3 faces the second hook plate 5.1, and the fixed seat 7 is connected with an opening of the slide rail main body 5.3, which is close to the through cavity 5.5 of the first hook plate 6.1; first draw-in groove 6.4 has been seted up on first hook plate 6.1, second draw-in groove 5.4 has been seted up on second hook plate 5.1, first draw-in groove 6.4 and second draw-in groove 5.4 are circular and relative setting, first draw-in groove 6.4 and the centre of a circle of second draw-in groove 5.4 are in same straight line, it should be understood that the draw-in groove sets up circularly for more convenient with the track round pin laminating, but set up to any shape or not use the draw-in groove all can, as long as can satisfy two relative track round pins realize tightening up then all fall into the scope of protection of above-mentioned claim.
