Abstract

The utility model relates to a clamping device, comprising a fixed clamping block, a movable clamping block which is sheathed on the fixed clamping block through a slide plate and moves along the fixed clamping block, etc. The slide plate is sheathed with a right regulating clamp plate and a left regulating clamp plate; a right handed extension spring is added between the upper end of the right regulating clamp plate and a fixed clamp plate; the upper end of an expansion handle which can rotate around a fixed point is arranged on one side of the upper end of the right regulating clamp plate; the right regulating clamp plate can be driven to move left when the expansion handle is wrenched; a pressure spring is added between the left regulating clamp plate and the fixed clamping block; the upper end of a clamping handle which can rotate around the fixed point is arranged on one side of the lower end of the left regulating clamp plate; the left regulating clamp plate can be driven to move left when the clamping handle is wrenched. As the slide plate of the movable clamping block of the utility model is longer, the clamping opening has a great regulating range; as the clamping handle and the expansion handle are used, the clamping force can be conveniently regulated, and the operation is easy, convenient and labor-saving.

Description

Binding clasp

The utility model relates to a kind of anchor clamps.

At present the normal anchor clamps that use of people mostly are spring clip or screw clamps, and these anchor clamps generally all exist folder mouthful adjustable range little and operational sequence is loaded down with trivial details, the shortcoming that wastes time and energy.

The purpose of this utility model is to provide a kind of easy and simple to handle and folder mouthful big anchor clamps of adjusting range.

The purpose of this utility model is achieved in that the utility model comprises that one is decided fixture block and is sleeved on by slide plate that decide on the fixture block can be along deciding moving fixture block that fixture block moves etc., be set with a right clamp and the left side of transferring on the slide plate and transfer clamp, the right side is transferred the upper end of clamp and is decided to add between the clamping plate dextrad extension spring, can be arranged on right clamp upper end one side of transferring around the upper end of opening handle that fixing point rotates, pull and open handle, can promote the right clamp of transferring is moved to the left, transfer clamp on a left side and decide to add between the fixture block stage clip, the upper end of the clamping lever that can rotate around fixing point is arranged on the side that the clamp lower end is transferred on a left side, pulls clamping lever and can promote a left side and transfer clamp to be moved to the left.

The utility model so its folder mouthful adjusting range is big, adopts clamping lever and the size of opening the conveniently adjusted clamping force of handle owing to the slide plate of moving fixture block is longer, and easy and simple to handle, laborsaving.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model releasing orientation schematic diagram.

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

As shown in Figure 1, pull and open handle 12, opening handle 12 rotates around fixing point 10, the upper end of opening handle 12 promotes the right clamp 11 of transferring left, the right clamp 11 of transferring is when the effect of extension spring 13 moves right, and as shown in Figure 2, right accent clamp 11 upper and lower bayonet sockets block slide plate 3 drive slide plates 3 and move right, moving fixture block 2 and decide that distance becomes greatly between the fixture block 1, anchor clamps open; As shown in Figure 1, hold and decide fixture block handle 7, when pulling clamping lever 8, clamping lever 8 rotates around fixing point 9, the left clamp 5 of transferring of the upper end promotion of clamping lever 8 is moved to the left, and the bayonet socket up and down of left at this moment accent clamp 5 blocks the moving fixture block 2 of slide plate 3 drives and is moved to the left, and finishes clamping process.As shown in Figure 2, when unclamping clamping lever 8, because the utility model is at clamping lever 8 with decide to add spring 6 between the fixture block handle 7, clamping lever 8 resets like this, and left side accent clamp 5 moves to right under stage clip 4 acts on and resets.

Claims (2)

1, a kind of binding clasp, it is characterized in that it comprise one decide fixture block (1) and by slide plate (3) be sleeved on decide on the fixture block (1) can along decide fixture block (1) mobile move piece (2) etc., be set with a right clamp (11) and the left side of transferring on the slide plate (3) and transfer clamp (5), the right side is transferred the upper end of clamp (11) and is decided to add between the clamping plate (1) dextrad extension spring (13), can be arranged on right clamp (11) upper end one side of transferring around the upper end of opening handle (12) that fixing point (10) rotates, pull and open handle (12), can promote dk transfers clamp (11) to be moved to the left, transfer clamp (5) on a left side and decide to add between the fixture block (1) stage clip (4), the upper end of the clamping lever (8) that can rotate around fixing point (9) is arranged on the side that clamp (5) lower end is transferred on a left side, pulls clamping lever (8) and can promote a left side and transfer clamp (5) to be moved to the left.

2, a kind of binding clasp according to claim 1 is characterized in that at clamping lever (8) and decides to add between the fixture block handle (7) spring (6).
