Abstract

The invention discloses a novel technical scheme of a steel wire clamp and provides a torsional spring with an additional handle. Junior-grade infants can easily and conveniently use the torsional spring, meanwhile several pages for facilitating page turning are also effectively constrained under the restraining effect of an embedded-clamped sharp-corner structure, and reading is very convenient and without difficulty. The technical scheme is that the torsional spring with the additional handle comprises a handle-free torsional spring, wherein the handle-free torsional spring is of a structure free of a front-arranged handle ring, the middle-section position is sleeved by a trapezium clamp block in an isosceles shape through a pair of clamp spring mantle cavities, the arc-shaped upwarping additional handle adhered with an anti-slipping rubber pad is designed on the trapezium clamp block, and meanwhile an embedded-clamped sharp angle formed by the lower edge position of the upwarping additional handle and the downward-inclining handle-free torsional spring.

Description

Torsion spring with auxiliary handle

Technical field:

The invention belongs to stationery apparatus field, specifically refer to the band of device on standing book clamp The torsion spring of auxiliary handle.

Background technology:

Publication No. CN1850517A, publication date on October 25th, 2006, invention (patent No. 200610081698X, authorized announcement date is to create entitled standing book clamp On July 22nd, 2009) Chinese invention patent project, disclose one read book auxiliary Instrument standing book clamp, it can position the page of the book of any edition type, simultaneously reliably Also having and book is supported the function faced upward, the design is drawn by one group of arranged side by side two piece is flexible Bar, the wire clip (torsion spring) of band forward handle circle at two ends, the sliding sleeve of square piece shape and The leg assembly of back side device is constituted, and main body telescopic lever can stretch, be convenient for carrying； When actually used, user is needed to utilize thumb food two finger of oneself by contact wire clip On handle circle and the force that matches of the tail end of wire clip, with the spring support in spring coil as axle The heart pulls open in the book-page clip opened is entered jaws by the wire clip at two ends respectively to be implemented to clamp Operation, this intrinsic wire clip and mode of operation thereof are for being grown up and older What inconvenience, moreover, intrinsic steel wire is not had for the user of relatively senior class The thinly scattered penetrating succinct moulding of folder is also advantageous to watch the content on page, but It is then to have for the vast more lower child of main foreigner tourists using this apparatus Many inconvenience and discomfort: owing to their hands is less, power is the least, original design steel wire Press from both sides is longer to the distance of tail end from handle circle (original design numbered 12) so that he Operation seem inconvenient because of painstaking, and cripetura this apart from the folder affecting wire clip Hold effect；It addition, several pages of pages reserved for flipbook is convenient the most also can be because of himself Elasticity and lacking effectively control structure and shift impact without authorization and read, these problems are all Need to improve and eliminate.

Summary of the invention:

The purpose of the present invention is aiming at the deficiency of above-mentioned original design wire clip and improves The torsion spring of new technical scheme band auxiliary handle of a kind of wire clip formed, it can be by Aforesaid problem and inconvenience are mitigated or eliminated.

The technical scheme is that and be achieved in that: it comprises stockless torsion spring, described stockless Torsion spring is the structure without forward handle circle, and a pair jump ring mantle cavity card is passed through at section position wherein It is cased with a trapezoidal fixture block in isosceles shape, trapezoidal fixture block is designed with curved upwarping The auxiliary handle being pasted with antiskid glue cushion of shape, the lower edge of the auxiliary handle simultaneously upwarped An inlay card wedge angle is formed between position and the stockless torsion spring having a down dip.

The invention has the beneficial effects as follows that lower child can be allowed to use is the lightest Convenient, meanwhile, several pages of pages reserved for flipbook is convenient also can be because of inlay card horn structure The effect of controlling and by operative constraint, read the most smoothly.

Accompanying drawing illustrates:

Fig. 1 is the state of facing lower plane design sketch (partly cuing open) of the design.

Fig. 2 is the left view planar effect picture (partly cuing open) of the design.

Fig. 3 is top view.

In each figure, 1 is stockless torsion spring, and 2 is auxiliary handle, and 3 is antiskid glue cushion, 4 For jump ring mantle cavity, 5 is trapezoidal fixture block, and 6 is inlay card wedge angle.

Detailed description of the invention:

Stockless torsion spring 1 as shown in Figure 1, Figure 3 preferably uses spring steel wire nest system to process, Its modeling structure is essentially identical with intrinsic wire clip, specifically comprises left end (front end) Jaws, the jig arm at position, stage casing and the spring coil of right-hand member (tail end), the most unmatched install The handle circle part of meter；The most trapezoidal fixture block of remainder 5 of the design, auxiliary handle 2 grades the most preferably use and set the mode production and processing being molded into moulding, as shown in Figure 1, Figure 2, Fig. 3 institute Show, at the back side two waist lower edge of a plate object in isosceles trapezoid inwardly downward in curly Process columnar jump ring mantle cavity 4 fixture block 5 in echelon do not closed, this trapezoidal fixture block The angle state of two jig arm at incline direction and position, stockless torsion spring 1 stage casing of two waists Match, so trapezoidal fixture block can be turned round with stockless by the jump ring mantle cavity under it The spring arm position of spring tightly wears blocks, and reaches firmly to be assembled；At trapezoidal fixture block On front end (left end) be designed with curved upwarp shape be pasted with the additional of antiskid glue cushion 3 Handle 2, the lower edge position of the auxiliary handle simultaneously upwarped and the stockless torsion spring stage casing having a down dip An inlay card wedge angle 6 is formed, as shown in Figure 1 between steel wire.Time specifically used, due to attached Add handle and be arranged on the position, stage casing of stockless torsion spring so that the little hands operation of child becomes Easily many；Meanwhile, that reserves for downward flipbook is convenient is not clipped under jaws Several pages of pages can also embed or left end or right-hand member inlay card wedge angle 6 wedge angle in, it is special Controlling of different structure acts on and by operative constraint, brings the most conveniently for reading page turning.

Claims (1)

1. the torsion spring of a band auxiliary handle, it comprises the stockless torsion spring without forward handle coil structures, it is characterized in that described stockless torsion spring section position wherein is covered with a trapezoidal fixture block in isosceles shape by a pair jump ring mantle cavity, trapezoidal fixture block is designed with the curved auxiliary handle being pasted with antiskid glue cushion upwarping shape, between lower edge position and the stockless torsion spring having a down dip of the auxiliary handle simultaneously upwarped, forms an inlay card wedge angle.
