Abstract

The utility model relates to a new type of holding device, which is composed of a main body for holding and a fixed crossarm provided with a chute. The main body mainly comprises a screw cap, a handle connected movably with the top of the screw cap, a slide rod slipping proportionally with the chute and an end nip. A clip-tongue is extended from the end nip is in the direction of the fixed crossarm to assist the fixed crossarm to clamp a workpiece. A screw and a pylome are arranged on the slide rod. A concave hole and a screw are also arranged at the joint between the end nip and the slide rod. A locating rod is connected with the pylome and the concave hole of the end nip. A threaded rod connecting slide rod and the screw of the end nip are cooperated with the screw cap. A spring is arranged between the slide rod and the end nip on the threaded rod. The utility model has the advantages of easy operation, tight and firm clamping for plate and convenience.

Description

Novel clamping device

Technical field:

The utility model relates to a kind of anchor clamps, especially refers to be used for the clamping device of two or two above sheet materials of clamping.

Background technology

What at present, be suitable for that clamping device that building board uses adopts is such structure: as shown in Figure 2: clamping device main body 1 ' is Type,

Type main body sheer pole 1 ' 2 little being inclined upwardly, cross tube 1 ' 1 is offered a screw, and in addition, a screw rod 2 ' top flexibly connects one handle 3 ', and described screw rod 2 ' passes

The screw of type main body.During clamping sheet material, turning handle 3 ', screw rod 2 ' drops to an appropriate location, realize the screw rod lower surface with

Type main body sheer pole 1 ' 2 shared clamping sheet materials.Like this clamping device of structure, the clamping contact-making surface of realization is very little, in the use, is easy to generate displacement between the sheet material, has influenced the machining accuracy of later process or caused between sheet material and sheet material combine closely, become flexible the clamping process complex operation.

Summary of the invention:

At the existing deficiency that exists, the utility model provides a kind of novel clamping device, its purpose be to provide a kind of simple to operation, sheet material clamping closely, carefully and neatly done, locate reliable novel clamping device.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

Novel clamping device, comprise the clamping main body and offer the fixedly crossbearer of chute, the clamping master mainly comprises nut, be movably connected on the handle of nut top end, the slide block and the end folder that match and slide with described chute, end folder extends a clip tongue to fixing crossbearer direction, cooperate fixedly crossbearer clamping work pieces, described slide block has been opened a screw and a through hole, the end folder is also offered shrinkage pool and screw with slide block concord place, through hole on a positioning rod connection slide block and the shrinkage pool on the end folder, one is connected the screw on slide block and the end folder with screw rod that above-mentioned nut matches, described screw rod is at the spacing place sheathed spring of slide block with the end folder.

The usefulness of technique scheme is:

Fixedly crossbearer presss from both sides with large tracts of land clamping sheet material with end, the common support that adds expansion link and screw rod is stressed, the suffered chucking power of sheet material is more even, combination closely between the sheet material, can be because of the increase of handle rotation to the sheet material chucking power, and the inconsistent phenomenon between generation sheet material, in addition, fixedly crossbearer has been formulated multiple dimensions, and the user can look the length of sheet material and select the fixedly crossbearer that is fit to board dimension for use, like this, fixedly can use a plurality of clamping bodies simultaneously on the crossbearer at one, it is balanced that the chucking power of each receptor site of sheet material reaches easily, and sheet material just is difficult for loosening, locatees reliable and simple to operate.

Description of drawings:

Below with accompanying drawing the utility model is described in detail:

Fig. 1 is the utility model structural upright schematic diagram;

Fig. 2 is the prior art constructions schematic perspective view.

The specific embodiment:

As shown in Figure 1, novel clamping device, comprise clamping main body 2 and offer the fixedly crossbearer 1 of chute 11, clamping main body 2 mainly comprises nut 21, be movably connected on the handle 22 of nut 21 top ends, the slide block 23 and the end folder 24 that match and slide with described chute 11, end folder 24 extends a clip tongue 241 to fixing crossbearer 1 direction, cooperate fixedly crossbearer 1 clamping work pieces, a screw and a through hole have been opened on the described slide block 23, end folder 24 is also offered shrinkage pool and screw with slide block 23 concords place, a positioning rod 25 connects the through hole on the slide block 23 and holds the shrinkage pool that presss from both sides on 24, one is connected the screw on slide block 23 and the end folder 24 with screw rod 26 that above-mentioned nut 21 matches, described screw rod 26 is at the spacing place sheathed spring 27 of slide block 23 with end folder 24.During use, release handle 22, end folder 24 spaces out to the spacing that is fit to clamp sheet material in the effect of spring 27 with slide block 23, slide block 23 cover snaps in the chute of fixing crossbearer 1, and slide block 23 slides into the position that is suitable for clamping, turning handle 22, end folder 24 rises, with the fixing crossbearer 1 common sheet material that clamps.The fixedly crossbearer 1 of the clamping device of this new structure has been formulated multiple dimensions, the user can look the length of sheet material and select the fixedly crossbearer 1 that is fit to board dimension for use, like this, fixedly can use a plurality of clamping bodies 2 simultaneously on the crossbearer 1 at one, because fixedly crossbearer 1 presss from both sides 24 with large tracts of land clamping sheet material with end, add that expansion link 25 is stressed with the common support of screw rod 26, the suffered chucking power of sheet material is even, combination closely between the sheet material, in the time of can not rotating because of handle 22 to the increase of sheet material chucking power, and the dislocation between generation sheet material, loosening phenomenon, the location of sheet material is more reliable and operate simple and convenient.

Claims

1, novel clamping device, it is characterized in that: described clamping device comprises the clamping main body and offers the fixedly crossbearer of chute, the clamping main body mainly comprises nut, be movably connected on the handle of nut top end, the slide block and the end folder that match and slide with described chute, end folder extends a clip tongue to fixing crossbearer direction, cooperate fixedly crossbearer clamping work pieces, described slide block has been opened a screw and a through hole, the end folder is also offered shrinkage pool and screw with slide block concord place, through hole on a positioning rod connection slide block and the shrinkage pool on the end folder, one is connected the screw on slide block and the end folder with screw rod that above-mentioned nut matches, described screw rod is at the spacing place sheathed spring of slide block with the end folder.
