Abstract

The utility model provides a tong which is mainly additionally provided with a pivoting part between a clamping part and a grab handle part of the tong. The pivoting part mainly combines a concave pivoting groove and a convex pivoting block by a screwing element, and causes the concave pivoting groove and the convex pivoting block to keep in the state of rotation. The structural strength of the pivoting part is enhanced by the pivoting mode of the concave pivoting groove and the convex pivoting block, and the failure of the tong is prevented. The pivoting part is provided with a clamping hole and a topping element in order to prevent the grab handle part or the clamping part from optionally swinging. The tong is converted into a properly operating type by the structure to fit different operating space.

Description

Clamp

[technical field]

The utility model relates to a kind of hand-held tool, is meant a kind of clamp especially, and it can adapt to different usage spaces and become different operational configurations and use, and is more suitable for the narrow space operation.

[background technology]

General clamp all includes a clamping section and a shank part, and when controlling this shank part, the folding that can control this clamping section comes the clamping object.The clamping section of existing clamp and shank part are a straight line to be arranged, and wrist flex operation in use causes the injury of so-called carpal tunnel syndrome (carpal tunnelsyndrome) easily, and is unfavorable for operating in narrow space or the confined space to the user.

Recently, the appearance of novel clamp is arranged again, No. 474238 (denomination of invention is: the clamp that is suitable for narrow space) disclosed as the TaiWan, China patent announcement, its mainly on the shank part of clamp two ends respectively form a L shaped pivoting part, and on the clamping section of clamp, form corresponding L shaped pivoting part, and by a pivot shank part and clamping section are pivoted, make the two become rotating sheathed relation; Yet, the mode of the pivoting part design of this existing clamp is not desirable to the greatest extent, because of the pivoting part of shank part and clamping section all L-shaped, and the contact-making surface between the L shaped pivoting part has only a side, only be suitable for the switching power that provides unidirectional, for needs just, reverse for the clamp of turn object, the structural strength deficiency of this pivoting part causes damage easily.

[utility model content]

Main purpose of the present utility model is to provide a kind of narrow space that is suitable for, and the high clamp of structural strength, and it can be adjusted to different configurations, adapting to various narrow space,

For achieving the above object, the utility model adopts following technical scheme: set up a pivoting part between the clamping section of clamp and shank part, this pivoting part mainly closes a spill pivot groove and a convex pivot agllutination with a screw tightening, and make it keep rotating state, and pivoting part is provided with clip hole and the top part of pulling, and prevents that like this shank part or clamping section from arbitrarily rocking.

Owing to adopted above-mentioned technical scheme, the utlity model has following advantage: make clamp can be transformed into suitable operational configurations by above-mentioned structure, to adapt to different operating spaces; Strengthen the structural strength of pivoting part in the pivot joint mode of spill pivot groove and convex pivot piece, prevent the clamp fault.The utility model is a kind of innovation and creation that quite have practicality and progressive in fact, quite is worth industrial circle to be promoted, and makes society know.

[specific embodiment]

The utility model relates to a kind of clamp, sees also Fig. 1 to shown in Figure 3, and this clamp 1 mainly comprises a clamping section 10, a pivoting part 20 and a shank part 30, wherein:

These clamping section 10 movable foldings are with the clamping object, and this shank part 30 grips the application of force for the user, and this is the architectural feature that generally has clamp now, is not emphasis of the present utility model place, does not repeat them here.

This pivoting part 20 comprises a pair of spill pivot groove 21, a pair of convex pivot piece 22, a pair of screw tightening 23, a pair of pad 24, a pair of top part 25 of pulling; This spill pivot groove 21 forms in an end of clamping section 10, and the left and right sides of spill pivot groove 21 is provided with pivot hole 210, and forms a room 211 in the bottom side of spill pivot groove 21; This convex pivot piece 22 slightly is a half round post, and convex pivot piece 22 axially on be formed with a perforation 220, upwards then be formed with several clip holes 221 in the footpath of convex pivot piece 22; This top part 25 of pulling is made up of an elastic component and a steel ball.

The utility model is in when assembling, is that the part 25 of being pulled in the top is earlier inserted in the room 211 of spill pivot groove 21, and pad 24 placed perforation 220 outer rims of convex geosynclinal block; Then convex pivot piece 22 is inserted in the spill pivot groove 21, makes the top part 25 of pulling be with clip hole 221 and engage shape, and make pad 24 be limited between spill pivot piece and the spill pivot groove 21; Penetrate the pivot hole 210 of spill pivot groove 21 and the perforation 220 of convex pivot piece 22 with screw tightening 23, and be inserted in pad 24 and be fixed at last in the pivot hole 210, make pivoting part 20 with clamping section 10 and shank part 30 pivots knot, and be rotating state, and the pivoting part 20 of the utility model clamp is with a spill pivot groove 21 sheathed convex pivot pieces 22, so can obtain best structural strength, and can avoid because of the not enough worry that generates fault of pivoting part 20 structural strengths.

See also Fig. 4 to shown in Figure 6, the utility model is by the design of pivoting part 20, and can make clamping section 10 and shank part 30 adjust different angles, and after adjusting required angle, can and push up the part 25 of pulling by clip hole 221 suitable clip power is provided, preventing that clamping section 10 and shank part 30 from arbitrarily rocking, and cause the unnecessary puzzlement of user.

The utility model palpus lay special stress on a bit, clamp of the present utility model can make its whole structure more perfect, especially in the quite limited field of the development space of this type of tool body scope, real symbolic animal of the birth year is when estimable, so the utility model definitely meets the requirement of progressive.

By last explanation as can be known, the utility model clamp can be transformed into different modes of operation, uses to adapt to various narrow space, and meets ergonomic designs.

Above said content is only for being used for explaining preferred implementation of the present utility model; be not that attempt is done any pro forma restriction to the utility model in view of the above; therefore; all have in that identical inventive concept is following do relevant any modification of the present utility model or variation; all must be included in the category of the utility model intention protection; wherein as shown in Figure 7; this screw tightening also can change by a pivot (23 ') to be replaced; and the effect of bringing into normal play; in addition; this spill pivot groove also can be arranged at shank part, and this convex pivot piece is arranged at the clamping section.
