Abstract

The utility model relates to an improved structure of a spring clamp. A positioning mechanism with an elastic clamping latch is arranged between two handles of the spring clamp to make the spring clamp additionally provided with an auxiliary positioning mechanism in biting and clamping operation to avoid the condition that a clamping device is loosened in the process of biting and clamping. Thus the clamping positioning function of the spring clamp is increased.

Description

Spring clip improves structure

The utility model relates to a kind of spring clip and improves structure, it is spring clip to be improved be designed to have a location mechanism between two handles, make spring clip in the interlock operation of construction, produce the situation that slippage is unclamped in the time of can not interlock taking place suddenly, make spring clip have more progressive.

According to general employed at present spring clip; though its moulding is various; but at its constructional design; but all be similar; its elastic force that only depends on spring is in interlock; and after interlock, do not design any assist location mechanism; especially use when the operation of two planks dos processing is lived in interlock; regular meeting is bigger because of the thickness of plank; when making its vibrations in cutting or boring or PROPEL big; will make the mouth part position of spring clip slide disengagement suddenly and influence construction, and make the user feel very puzzlement.The inventor in view of this, carried out many-sided research, finally develop a kind of improvement structure, it is provided with between two handles of spring clip has an assist location mechanism, make spring clip in the action of interlock, really can reach interlock completely and fix, and more known spring clip structure tool progressive and practicality.

Therefore, main purpose of the present utility model is to provide a kind of spring clip to improve structure, can make spring clip in the use, increases to have an assist location mechanism, make its sting in the folder operation firm more really.

The utility model relates to a kind of spring clip and improves structure, it is characterized in that, between two handles of spring clip, be provided with and have a location mechanism, this detent mechanism is by a sleeve, one axis body arrange in pairs or groups a tenon and one the compression spring constitute, wherein, the top of sleeve is in conjunction with the inner edge surface suitable position place that is fixed on handle, it has an inner diameter volume, after can being fixed on the inner edge surface suitable position place of handle for the end limit combination of axis body, but its other end limit then embedding is inserted in the internal diameter of this sleeve, again, the opening part position, one end limit of sleeve and axis body intercalation is had a chimb by moulding, can articulate for base limit end with tenon, and the compression spring of arranging in pairs or groups is arranged between the base limit of sleeve outer edge limit and tenon, on the base limit of tenon, then be provided with and have an aperture, this aperture is bigger slightly than axis body external diameter, it is by the setting of compression spring, can make tenon handle in the spring clip in application of force pressed state not following time, make the inner edge surface in aperture be supported and stop axis body, and when the tenon handle application of force is pushed, made the inner edge surface and the axis body in aperture discharge immediately, make it to become and have one and help detent mechanism.

Below accompanying drawing is briefly explained:

Fig. 1 is D structure figure of the present utility model;

Fig. 2 is planar configuration figure of the present utility model;

The planar configuration figure that Fig. 3 locatees behind the clamping plank for the utility model.

For structure of the present utility model and function are further understood, cooperate following accompanying drawing to be described in detail as follows below:

See also Fig. 1 to shown in Figure 3, the utility model is at two handles 11 of spring clip 1,12 settings have a location mechanism 2, this detent mechanism 2 is by a sleeve 21, one axis body, 22 collocation one tenons 23 and a compression spring 24 constitute, wherein, the top of sleeve 21 is in conjunction with the inner edge surface suitable position place that is fixed on handle 11, it has an internal diameter 211 spaces, after can being fixed on the inner edge surface suitable position place of handle 12 for the end limit combination of axis body 22, but its other end limit then embedding is inserted in the internal diameter 211 of this sleeve 21, again, sleeve 21 is had a chimb 212 with the opening part position, an end limit of axis body 22 intercalations by moulding, can articulate for base limit end 231 with tenon 23, and the compression spring 24 of arranging in pairs or groups is arranged on 232 on the base limit of sleeve 21 outer edge limits and tenon 23, tenon 23, then design on its base limit 232 and have an aperture 2321, this aperture 2321 is bigger slightly than axis body 22 external diameters, it is by the setting of compression spring 24, can make two handles 11 of spring clip 1,12 when the normal condition of the general not application of force, make under the effect that this tenon 23 can outwards stretch at the compression elasticity of compression spring 24, make the aperture 2321 on the tenon 23 base limits 232 crooked, contact abrasion state and have one with 22 of axis bodies by the inner edge surface 2322 in this aperture 2321, so that two handles 11, located for 12, otherwise, when the handle 230 of tenon 23 is made progress by the application of force, moment can make on aperture 2321 and the sleeve 21 on the tenon 23 base limits 232 internal diameter 211 both present parastate, and the limit emaciated face of the inner edge surface 2322 that makes aperture 2321 and axis body 22 from, make two handles 11,12 form and can free upper and lower displacement move, once when again the power that applies at handle 230 places of this tenon 23 being discharged, can make two handles 11,12 have at once and stop the bamboo shoot anchor point in a flash.Under the spatial arrangement of above-mentioned each member, can make spring clip 1 in the use, as long as push the application of force to tenon handle 230 with finger, just can make 11,12 of two handles present movable state of controlling, once the application of force on the finger is when decontroling, will have the bamboo shoot of stopping anchor point, as brake gear, very convenient practicality.

In sum, owing to the utlity model has above-described good characteristic, make it on manipulating, give the usefulness that does not have for existing spring clip and have progressive, make it to become a product that has a practical value.

Claims (1)

1, a kind of spring clip improves structure, it is characterized in that, between two handles of spring clip, be provided with and have a location mechanism, this detent mechanism is by a sleeve, one axis body arrange in pairs or groups a tenon and one the compression spring constitute, wherein, the top of sleeve is in conjunction with the inner edge surface suitable position place that is fixed on handle, it has an inner diameter volume, after can being fixed on the inner edge surface suitable position place of handle for the end limit combination of axis body, but its other end limit then embedding is inserted in the internal diameter of this sleeve, again, the opening part position, one end limit of sleeve and axis body intercalation is had a chimb by moulding, and arrange in pairs or groups one the compression spring be arranged between the base limit of sleeve outer edge limit and tenon, on the base limit of tenon the setting have an aperture, this aperture is bigger slightly than axis body external diameter.
