Abstract
Disclosed is a quick-change gripping head of a lig saw, which is designed for solving problems of loose and unreliable clamping and rather difficult demounting of similar well-known products. The quick-change gripping head comprises a reciprocating lever, a gripping head, a turn knob and a saw blade, and has the design points that the gripping head is inserted into one section of the reciprocating lever, the inserted section is fixedly connected with the gripping head, the gripping head is arranged in the turn knob, a slot of the gripping head coming out from the turn knob is fixedly connected with an elastic damping ring, pressing blocks are disposed on the inclined plane of the gripping head, and the saw blade is positioned between the two pressing blocks. The saw blade is inserted through the rotation of the turn knob, then a cylindrical pin is compressed and stressed under the acting force of a spring, and the resultant force is formed at both sides of the saw blade along the inclined plane, therefore the saw blade is clamped. When changing the saw blade, a wrench is pulled toward the opposite direction and rotated by 90 degrees by pressing the second arrow head, a clamping piece loosens the pressing blocks under the action of a slope while pushing the cylindrical pin to move upwards, namely, the turn knob is restored toward the opposite direction, thereby changing the saw blade. The quick-change gripping head is applied to the quick changing and clamping of a plurality of curve saw blades, and has advantages of reliable clamping, convenient demounting and rather low cost.
Description
Technical field
The utility model relates to a kind of sweep-saw quick chuck.
Background technology
Known like product sweep-saw quick chuck publishes in Chinese patent literature, but most design clamping reliabilities owes firmly, difficult the dismounting, and relative cost is higher.Often can only use a kind of saw blade of specification, and structural design exists certain defective.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of sweep-saw quick chuck to this area, and purpose is to make it can solve the clamping reliability to owe firmly, difficult dismounting, and relative cost is higher, technical problem that can only the single specification saw blade of clamping.The purpose of this utility model is to realize by the following technical solutions.
A kind of sweep-saw quick chuck, this quick chuck comprises reciprocating lever, chuck, knob, saw blade, its main points are that one section of reciprocating lever is inserted chuck, inserting section fixedlys connected with chuck, chuck is arranged in the knob, is provided with the slope in knob, and it is fixedly connected by circlip that chuck exposes the draw-in groove of knob, briquetting is arranged at the inclined-plane of chuck, and its effect is to make the chuck of insertion play the effect of guiding when knob rotates.Saw blade places between two briquettings.
The side of the knob of described sweep-saw quick chuck is provided with spanner, in the square hole of briquetting straight pin is set, and boss is with fastener, and fastener is fixedlyed connected with the boss that exposes chuck end.
In the described reciprocating lever of described sweep-saw quick chuck gland is set, the top of gland is provided with spring, spring base, and the middle part of gland is equipped with saw blade.
By above-mentioned technical scheme,, there are the saw blade of step or wheel chair access saw blade to clamp owing to form chucking power in the saw blade both sides.Therefore, be applicable to quick change, the clamping of multiple curve saw blade.It is reliable to have clamping, convenient disassembly, lower-cost characteristics.Be applicable to the sawing of various materials, market prospects are good.

The specific embodiment
Embodiment of the present utility model is to be assembled into example.In conjunction with Fig. 1～Fig. 8, spring base 11, spring 10, gland 8 are packed in the reciprocating lever 1 successively.Two straight pins 7 are respectively charged in the square hole 18 of briquetting 6, and 15 bottoms, inclined-plane of the symmetrical chuck 2 of packing into are on the reciprocating lever 1 of packing into together again, fixing with the reciprocating lever and the chuck welding of this section then.Two fasteners 9 are inserted in respectively on the boss 17 of briquetting 6, and first arrow 12 of knob 3 is played the effect of vertical indication, aim at the centre of one fastener 9, and are inserted on the chuck 2, and circlip 5 snaps in the draw-in groove 20.Knob 3 is pulled spanner 14 by second arrow, 13 directions, and promotion straight pin 7 moved up when horizontal half-twist, fastener drove briquetting 6 under the effect on inclined-plane 15, inserted saw blade 4, and knob 3 is resetted in the other direction.Straight pin 7 is stressed in the active force lower compression of spring 10, and 15 pairs of saw blade 11 both sides form and make a concerted effort along the inclined-plane, clamp saw blade.And saw blade is as the elastic force of loosening a little spring, and promptly spring stretches and gives " supply " again, makes saw blade be in clamped condition all the time.Then pull spanner 14 in the opposite direction by second arrow 13 when changing saw blade, half-twist, fastener promote straight pin 7 in the loosening briquetting 6 and move up under the effect on slope 19, are about to knob 3 resetting round about, change saw blade 4.The end of described reciprocating lever 1 is mounted in the casing of sweep-saw.
