Description

Improved structure of fixture with enlarged clamping distance

The present invention provides a technical field of a jig, in particular, a technically improved jig-enhanced structure having an enlarged clamping distance, wherein the clamping portion is provided with an extension arm, and the working end of the operating handle is half-arranged to be a flat cover. Assembly and mold demolding is fast.

According to the first figure, the conventional jig includes a clamp provided with two operating handles 11. The two operating handles 11 are mutually interlocked, and one end is provided with a holding end, and the positioning device is mounted on the two holding ends. During the other end, the other end of the operating handle 11 is provided with an axial slot 12 which is offset to the opposite sides and which does not have a alignment. The clamping jaw is provided with a clamping block and an extending arm 13 extending from the inner surface of the clamping block. The extension arm 13 is inserted into the axial slot 12 of the clamp to adjust the size of the clamp by the extension or retraction of the extension arm 13, and a radial slot 14 is formed in the handle 11. The locking member 15 is inserted into the elastic member 16, the locking member 15 and the elastic member 16 are provided for the extension arm 13 to be assembled therethrough.

However, when the operating handle 11 forms the radial slot 14 and the axial slot 12, since the two slots of the radial slot 14 and the axial slot 12 are slots in different directions, the two slots are formed in the switch. When the mold is used, it must be divided into two The second action can be formed, which has the disadvantages of low speed, increased cost and insufficient competitiveness.

In addition, when the operating handle 11 is assembled and formed, its radial slot 14 is for the locking member 15 and the elastic member 16 to be inserted radially, and the extending arm 13 is inserted by the axial slot 12, and the locking member 15 must be elasticized. The component 16 is threaded into the extension arm 13, however, the aforementioned assembly of the fastener 15 and the elastic member 16 into the extension arm 13 is an assembly mode of the scorpion image. Since the extension arm 13 is inserted into the axial slot 12, the fastener 15 and the elastic member 16 are assembled in an invisible mode, and the assembly process is slow.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, the consumers are eagerly awaiting, and the relevant industry must strive to develop the goal and direction of breakthrough.

The author of this creation provides a designer of a modified structure with an enlarged clamping distance.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, the implementation method and the schema are as follows: See the second to sixth figures, this creation provides an expansion The clamping distance improving structure comprises: a first and second operating handles 20, 30 respectively comprising a working end 21, 31, a pivoting portion 22, 32 and a holding end 23, 33, the working end 21, 31 and the pivoting portions 22, 32 form the rear half A when integrally formed, so that the first and second operating handles 20, 30 form the pivoting portions 22, 32 of the rear half A are pivotally connected to each other and pivoted Positioning a first elastic member 40 and a shaft member 41 at the same time, a positioning device 50, the positioning device 50 is obliquely mounted between the first and second operating handles 20, 30, and the main working end 21, 31 is the front half B. The clamping portion 70 includes a clamping block 72 at one end and a clamping portion 71. The clamping block 72 is fixed at the other end to an extending arm 73. Therefore, the extending arm 73 of the clamping portion 70 and A second or three elastic members 42 and 43 are assembled in a planar manner on the working end 31 and the rear half A can be viewed at a glance. In the assembly, the two fixing bolts 81, 82 in the form of wedge-shaped levers are fixed to the cover body 60 to the rear half A of the working end 21, so that the assembly can be fast and accurate, and the production is advantageous, and the demoulding of the mold production only needs one action. It can be achieved, and it will be faster to improve the market competitiveness.

The improved structure of the clamp with the enlarged clamping distance, wherein the first and second operating handles 20, 30 working end 21, 31 to the rear half portion A of the pivoting portion 22, 32 are provided with a plurality of recessed slots 24 and recessed slots 24 ribs 25, With the recessed grooves 24 and the ribs, the materials can be reduced, the weight can be reduced, and the structure can be strengthened.

Referring to the third and fourth figures, when used as a clamp, the positioning device 50 between the first operating handle 20 and the second operating handle 30 is released, and the first elastic member 40 is immediately stretched to the shape of the two jaws 71, 72. (As shown in the fourth figure), when the two handles are gripped by the first operating handle 20 and the gripping ends 23, 33 of the second operating handle 30, the two jaws 71, 72 are clamped to each other. And the positioning device 50 is capable of maintaining the clamped state of the two jaws 71, 72. At this time, the two extension arms 73 are retracted into the inside of the working end 21.

Referring to the fifth and sixth figures, when the clamping distance is to be expanded, the two extending arms 73 must be pulled out, and the clamping distance between the two clamping jaws 71, 72 is doubled by the length of the two extending arms 73. When the extension arm 73 is pulled out, the second or third elastic members 42, 43 still hold the two extension arms 73, and the two wedge-type locking bolts still retain the two extension arms 73 at any time.

It can be seen from the above that the improved structure of the fixture with the extended clamping distance is indeed the first in the industry and meets the novel requirements of the new patent, and its comprehensive innovative design meets the progressive requirements of the new patent. The clamping arm is provided with an extension arm, and the working end of the operating handle is half-designed as a separate cover body, which can achieve planar assembly and mold demolding fast, and is suitable for better industrial utilization.
